Therapeutic strategies to modulate gut microbial health: Approaches for sarcopenia management.

Sarcopenia is a progressive and generalized loss of skeletal muscle and functions associated with ageing with currently no definitive treatment. Alterations in gut microbial composition have emerged as a significant contributor to the pathophysiology of multiple diseases. Recently, its association with muscle health has pointed to its potential role in mediating sarcopenia. The current review focuses on the association of gut microbiota and mediators of muscle health, connecting the dots between the influence of gut microbiota and their metabolites on biomarkers of sarcopenia. It further delineates the mechanism by which the gut microbiota affects muscle health with progressing age, aiding the formulation of a multi-modal treatment plan involving nutritional supplements and pharmacological interventions along with lifestyle changes compiled in the review. Nutritional supplements containing proteins, vitamin D, omega-3 fatty acids, creatine, curcumin, kefir, and ursolic acid positively impact the gut microbiome. Dietary fibres foster a conducive environment for the growth of beneficial microbes such as Bifidobacterium, Faecalibacterium, Ruminococcus, and Lactobacillus. Probiotics and prebiotics act by protecting against reactive oxygen species (ROS) and inflammatory cytokines. They also increase the production of gut microbiota metabolites like short-chain fatty acids (SCFAs), which aid in improving muscle health. Foods rich in polyphenols are anti-inflammatory and have an antioxidant effect, contributing to a healthier gut. Pharmacological interventions like faecal microbiota transplantation (FMT), non-steroidal anti-inflammatory drugs (NSAIDs), ghrelin mimetics, angiotensin-converting enzyme inhibitors (ACEIs), and butyrate precursors lead to the production of anti-inflammatory fatty acids and regulate appetite, gut motility, and microbial impact on gut health. Further research is warranted to deepen our understanding of the interaction between gut microbiota and muscle health for developing therapeutic strategies for ameliorating sarcopenic muscle loss.

Cardiovascular profile drugs and the state of periodontal tissues

People with CVD, mostly over 50 years of age, regularly take medications such as beta-blockers (BBs), angiotensin-converting enzyme inhibitors (ACEIs), calcium channel blockers (CCBs), angiotensin II receptor blockers (ARBs), statins and acetylsalicylic acid (ASA). Periodontal tissue disease (PTD) occurs in the age group 35–44 years in 60% of cases, in the group of people 65–74 years – about 70%, that is, in that period of life when cardiovascular disease (CVD) begins to develop and progress. Some cardioprotective drugs, such as antihypertensives, cause xerostomia. Medication-induced xerostomia is one of the common causes of oral health problems in older adults who are on long-term drug therapy. Xerostomia is a common debilitating condition that causes problems such as dysphagia, loss of taste, and oral pain, as well as increasing the risk of tooth decay and oral infections. Drug-induced gingival overgrowth is an abnormal hypertrophy of the gingiva that can be caused by a number of medications, including calcium channel blockers. Drug-induced gingival overgrowth is characterized by the accumulation of connective tissue that primarily affects the anterior regions of the upper and lower jaw, and also causes problems with oral hygiene, which leads to susceptibility to infections and periodontal disease and can lead to tooth loss. Anticoagulants used in CVD due to the risk of bleeding require special approaches in the prevention and therapy of periodontal tissue disease. The possibilities of using statins in PTD due to their pleiotropic properties, independent of hypolipidemic action. The review article is devoted to the influence of drugs of cardiovascular profile on the state of periodontal tissues and mechanisms of development of side effects, as well as the possibilities of using statins taking into account their pleiotropic effects.

Mitochondrial Reactive Oxygen Species Dysregulation in Heart Failure with Preserved Ejection Fraction: A Fraction of the Whole

Heart failure with preserved ejection fraction (HFpEF) is a multifarious syndrome, accounting for over half of heart failure (HF) patients receiving clinical treatment. The prevalence of HFpEF is rapidly increasing in the coming decades as the global population ages. It is becoming clearer that HFpEF has a lot of different causes, which makes it challenging to find effective treatments. Currently, there are no proven treatments for people with deteriorating HF or HFpEF. Although the pathophysiologic foundations of HFpEF are complex, excessive reactive oxygen species (ROS) generation and increased oxidative stress caused by mitochondrial dysfunction seem to play a critical role in the pathogenesis of HFpEF. Emerging evidence from animal models and human myocardial tissues from failed hearts shows that mitochondrial aberrations cause a marked increase in mitochondrial ROS (mtROS) production and oxidative stress. Furthermore, studies have reported that common HF medications like beta blockers, angiotensin receptor blockers, angiotensin-converting enzyme inhibitors, and mineralocorticoid receptor antagonists indirectly reduce the production of mtROS. Despite the harmful effects of ROS on cardiac remodeling, maintaining mitochondrial homeostasis and cardiac functions requires small amounts of ROS. In this review, we will provide an overview and discussion of the recent findings on mtROS production, its threshold for imbalance, and the subsequent dysfunction that leads to related cardiac and systemic phenotypes in the context of HFpEF. We will also focus on newly discovered cellular and molecular mechanisms underlying ROS dysregulation, current therapeutic options, and future perspectives for treating HFpEF by targeting mtROS and the associated signal molecules.

Healthcare performance for patients with heart failure in Iran: addressing the tip of the iceberg.

Chronic diseases, such as heart failure with reduced ejection fraction (HFrEF), remain significant factors in the healthcare burden in Iran. Healthcare systems must have comprehensive data on the current usage, costs, and quality of care to tackle these challenges and formulate strategic plans effectively. The study included 209 patients with a mean age of 58 years (SD = 16.5) who met the inclusion criteria of having an ejection fraction of less than 40% and a confirmed diagnosis of HFrEF. This study used nationally representative data to assess the healthcare usage, costs, and quality of HFrEF management in Iran. The most used services were medication dispensing (76%) and outpatient visits (53%), while rehabilitation (3%) and homecare (2%) were used less frequently. The annual per-patient direct medical cost was $1,464, with $308 (21%) paid out-of-pocket (OOP). Hospitalization accounted for most of the total cost (68%), and pharmacy expenses comprised the largest portion of OOP payments (46%). Echocardiography was performed for 91.1% of patients upon admission. Only 71.6% of patients had arrangements for a cardiology visit within seven days following hospital discharge. Additionally, only 67.5% of patients received prescriptions for angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, and 85% were prescribed beta-blockers. Patients with heart failure in Iran face challenges in accessing adequate cardiac care, including a lack of care continuity and advanced cardiac services. The study provided an essential benchmark for future healthcare reform.

The role of beta blockers in the treatment of cardiovascular diseases

Beta-blockers are used to treat various cardiovascular diseases, including hypertension and chronic heart failure. They act by suppressing the effects of catecholamines through various pathways and affect heart rate, strength, and renin release, providing antihypertensive and anti-ischemic effects. The individual effects of various drugs on clinical outcomes in this group were determined according to characteristics of the patient, underlying disease, and type of beta-blocker used. In recent years, beta-blockers have faced a serious obstacle when new guidelines on hypertension suggest their use as second-line therapy after angiotensin converting enzyme inhibitors, angiotensin receptor blockers and slow calcium channel blockers in the absence of clear indications. In fact, these recommendations were based on meta-analyses that showed that beta-blockers have fewer beneficial effects on overall mortality, cardiovascular events, and brain stroke. In addition, according to currently available data, the appointment of beta-blockers for diseases such as heart failure with preserved ejection fraction and stable coronary heart disease can cause more harm than good outcomes. Bisoprolol is a beta-blocker with the highest selectivity for beta1-adrenergic receptors, which determines the rare frequency of side effects that develop because of its use. This review presents current data on the use of beta-blockers for treating cardiovascular diseases, with an emphasis on the use of bisoprolol.

PHARMACOLOGICAL STRATEGIES TO PREVENT CARDIOVASCULAR EVENTS IN HIGH-RISK PATIENTS

INTRODUCTION: Cardiovascular diseases (CVDs) remain the leading cause of global mortality, and high-risk patients, such as those with a history of myocardial infarction, diabetes, uncontrolled hypertension, or severe dyslipidemia, are especially vulnerable to adverse cardiovascular events. Pharmacological strategies aimed at preventing these events in high-risk patients are essential to reduce morbidity and mortality associated with CVDs. These strategies include the use of antiplatelet agents, statins, angiotensin-converting enzyme inhibitors (ACEIs), and beta-blockers, which have shown efficacy in the secondary prevention of events such as myocardial infarction and stroke. OBJECTIVES: Given the importance of this topic, this study aims to explore the most effective pharmacological strategies to prevent cardiovascular events in patients considered at high risk. The study aims to elucidate the main drugs used, their mechanisms of action, as well as the relevance of their clinical application for the reduction of fatal and non-fatal cardiovascular events in these patients. METHODOLOGY: The study was developed based on an integrative literature review, based on searches in the Virtual Health Library (VHL), PubMed and SciELO databases. The search terms used included: “Cardiovascular prevention”, “High-risk patients”, and “Pharmacological strategies”. Articles published in the last five years were selected to ensure the relevance and timeliness of the information. RESULTS: Pharmacological strategies to prevent cardiovascular events in high-risk patients include the use of antiplatelet agents such as aspirin, which reduces platelet aggregation and prevents arterial thrombosis. Statins, which reduce LDL cholesterol levels, have been shown to significantly reduce the risk of myocardial infarction and stroke. In addition, ACE inhibitors and beta-blockers have shown benefits in patients with heart failure and hypertension, reducing cardiovascular mortality. Individualizing treatment, considering the comorbidities and characteristics of each patient, is essential to optimize clinical results. CONCLUSION: Pharmacological strategies play a crucial role in the prevention of cardiovascular events in high-risk patients. The combination of medications such as antiplatelet agents, statins, ACE inhibitors and beta-blockers, when applied individually and according to clinical guidelines, can significantly reduce the incidence of serious cardiovascular events. Awareness of the importance of the correct use of these therapies and adherence to treatment are essential to improve the quality of life and increase the longevity of patients.

Retrospective Analysis of Factors Influencing the Hemoglobin Level-increasing Effect of Sodium-glucose Co-transporter-2 Inhibitors.

In several studies, Sodium-glucose co-transporter-2 inhibitors (SGLT2i) have been reported to increase hemoglobin (Hb) levels. In a study in which Hb levels were compared between patients who received SGLT2i and dipeptidyl peptidase-4 inhibitors, some patients exhibited increased Hb levels (>1.0 g/dl), whereas some exhibited unchanged Hb levels. Notably, several factors may influence the Hb-increasing effect of SGLT2i. This study aimed to analyze the factors influencing the Hb-increasing effect of SGLT2i. Type 2 diabetes patients were divided into three groups: SGLT2i (SGLT2i only group, n=36), those receiving a combination of SGLT2i and angiotensin-converting enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARBs) (SGLT2i+ACEi/ARBs group, n=32), and those not receiving these drugs (control group, n=49). We retrospectively analyzed Hb changes in these groups. Kaplan-Meier curves compared Hb changes from SGLT2i initiation to day 63, with an Hb increase defined as ≥0.5 g/dl. In addition, sex, age, ACEi/ARBs, estimated glomerular filtration rate, and hematocrit levels were analyzed using Cox proportional hazards as factors influencing Hb-increasing events. Hb-increasing event rates were 61%, 41%, and 20% in the SGLT2i only, SGLT2i+ACEi/ARBs, and control groups, respectively. The Kaplan-Meier curves showed significantly higher Hb-increasing event rates in the SGLT2i only group than in the control and SGLT2i+ACEi/ARBs groups. In the Cox proportional hazards model, ACEi/ARBs use was associated with a 39% reduction in the incidence of Hb-increasing events. SGLT2i exhibit a Hb-increasing effect, which may be reduced by ACEi/ARBs.

Clinicopathological Features of Membranous Nephropathy Complicated by IgA Nephropathy: A Retrospective Analysis of Seven Cases.

Aims/Background Both membranous nephropathy (MN) and immunoglobulin A nephropathy (IgAN) are immune complex-mediated glomerular diseases, but the concurrent occurrence of these two conditions in the same patient is not common, a phenomenon that is currently not supported by clinical data in terms of treatment and prognosis. This study explores the clinical and pathological characteristics, as well as the treatment outcomes, of patients affected by MN and IgAN simultaneously. Methods The clinical data, pathological features, and diagnostic and therapeutic information of seven cases of MN complicated by IgAN, treated between December 2015 and December 2022, were retrospectively analyzed. Results Among the seven cases, there were two male and five female patients, with an average age of 57.3 ± 9.2 years. All patients presented with clinical manifestations of proteinuria and edema upon admission, with an average 24-hour urine protein of 3716.6 ± 1519.4 mg/24 h. Phospholipase A2 receptor (PLA2R) expression was detected in all seven cases, and nephrotic syndrome was clinically diagnosed in five cases. Additionally, all seven cases showed microscopic hematuria, with intermittent gross hematuria in two cases. All seven patients included in this study underwent renal biopsy. After disease staging, the patients had MN stages I-III and IgAN stages II-III. Pathological findings revealed abnormal glomerular basement membrane (GBM) and diffuse immunoglobulin G (IgG) deposition in the subepithelial space, predominantly of the IgG4 subtype. Simultaneously, there was diffuse mesangial zone deposition of immunoglobulin A (IgA) to varying degrees, co-localization of complement component C3 and IgA, and mesangial cell proliferation. Treatment strategies included angiotensin-converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) in combination with steroids or immunosuppressive therapies such as tacrolimus, cyclophosphamide, and rituximab. After 2-6 months of treatment, all patients achieved complete remission with a favourable prognosis. Conclusion MN accompanied by IgAN tends to occur more frequently in middle-aged and elderly individuals, with a relatively low incidence. The latent feature of the comorbidities manifests as a form of IgAN superimposed on the background of MN. Utilizing ACEI or ARB in combination with steroids or various immunosuppressive therapies represents a potentially effective treatment strategy.

Significant regression of left ventricular hypertrophy in patient with arterial hypertension during antihypertensive treatment with perindopril and atorvastatin

Left ventricular hypertrophy (LVH) in arterial hypertension (AH) is one of the modifiable risk factors for cardiovascular events and serves as a justified goal for antihypertensive therapy. The article presents follow-up of a 60-year-old female with AH, hyperlipidemia, and discovered of LVH on the data of electrocardiography and echocardiography. In addition to the SokolowLyon and Cornell voltage criteria, the baseline echocardiographic examination revealed and increase in thickness of the ventricular septum and the left ventricular (LV) posterior wall, an increase in LV myocardial mass and LV myocardial mass index. The patient was recommended to take a drug of the class of angiotensin converting enzyme inhibitors perindopril and atorvastatin. The patient regularly received therapy and periodically underwent repeated echocardiographic examinations. After 40 months follow-up there are a significant decrease in septal hypertrophy (from 1.22 to 0.76 cm, -37.7%), LV posterior wall (from 1.05 to 0.49, -53.3%), as well as LV myocardial mass (from 197.9 to 96 g, -51.5%) and LV myocardial mass index (from 111.18 to 59.11 g/ m2, -51.5%). Thus, during the entire period of follow-up, the LV mass decreased almost twice. There was a decrease in the size of the left atrium, the relative wall thickness, with the same parameters of LV volumes, characteristics of systolic and diastolic function. Among the favorable factors contributing to significant LVH regression, high adherence to treatment, the efficacy of angiotensin converting enzyme inhibitors and the possible antihypertrophic influence of atorvastatin are discussed.

Comparison of Traditional and Intensive Cardiac Rehabilitation on Dietary Behavior and Clinical Risk Factor Outcomes

Purpose: The objective of this study was to assess differences in dietary behavior and clinical risk factor outcomes and explore predictors of change among patients participating in traditional and Pritikin intensive cardiac rehabilitation (CR). Methods: This secondary analysis of cardiac registry data from 2015 to 2021 included patients participating in traditional CR (n = 420) or Pritikin intensive CR (n = 1005) at a single hospital site. Dietary behavior outcomes included the Rate Your Plate measure, while clinical risk factor outcomes included fasting lipids, blood pressure, anthropometrics, functional outcomes, and psychosocial assessment. Analysis of covariance examined a difference in Rate Your Plate scores between CR groups. Multivariate analysis of covariance was used to determine differences in clinical risk factor variables between CR groups. Predictors of change in dietary behavior and clinical risk factors were determined through multiple bivariate linear regression models within each CR group. Results: Both CR programs led to significant improvements though more change was observed among Pritikin intensive CR participants in dietary behavior, anthropometrics, and fasting lipids. Status as a current or recent smoker was not a significant predictor of dietary behavior. Male sex, status as a current or recent smoker, beta-blockers, and angiotensin-converting enzyme inhibitors prescribed were not significant predictors of total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, or non–high-density lipoprotein cholesterol for traditional and Pritikin intensive CR groups. There were not significant predictors of blood pressure, body mass, or waist circumference. Conclusion: Although participation in either CR program yielded cardiometabolic benefits, Pritikin intensive CR patients exhibited significantly greater improvements in dietary behavior and clinical risk factors.

Unveiling the slow digestion and peptide profiles of polymerised whey gel via heat and TGase crosslinking: An in vitro/vivo perspective

Polymerised whey is widely used in dairy products and can affect digestibility when its high-molecular-weight aggregates and gel structure are modified. This study investigated the digestibility, peptide profiles and satiety of modified whey protein isolate (MWPI) pre-heated with transglutaminase. Results showed that 43.06 % of MWPI was digested during the 4-h in vitro digestion, indicating a slow digestion rate. Compared with whey protein isolate (WPI), MWPI yielded 103 peptides with higher abundance following in vitro digestion, including 17 angiotensin-converting enzyme inhibitors and 1 dipeptidyl peptidase-4 inhibitor. Visual analytics indicated differential peptides located at distinct α-helix and β-sheet of β-lactoglobulin, α-lactalbumin and bovine serum albumin. MWPI gavage extended stomach retention time, decreased intestinal propulsion rate from 75.60 % (WPI group) to 33.72 % in 30 min and enhanced satiety within 120 min compared with WPI. Overall, whey polymerisation modulates protein–enzyme interactions, releasing different peptides and enhancing satiety.

5-year valve academic research consortium-3 outcomes and predictors of mortality in a 10-year Asian transcatheter aortic valve implantation registry

Abstract Background Transaortic valvular implantation (TAVI) has revolutionised the management of aortic stenosis (AS). Uptake in Asia has caught up in recent years, after an initial lag due to expensive cost, limited subsidies, and scarce accessibility. Hence, longitudinal outcomes of TAVI remain largely unknown in Asian patients. Purpose This study aims to present the 5-year mortality endpoints in an Asian cohort followed up over a decade. Methods 253 patients with symptomatic severe aortic stenosis status post TAVI were retrospectively enrolled at a tertiary academic hospital from 2010-2021. The main outcomes were defined as short-term (30-day), mid-term (1-year) and long-term (5-year) all-cause mortality. Baseline demographics, procedural findings and clinical outcomes were analysed. Kaplan-Meier curves and multiple Cox regression analyses were constructed. Results The mean age was 75.2 + 10.2 years. 120 (47.4%) patients were female and 167 (66%) were Chinese. 168 patients (66.7%) received balloon-expandable valves, 80 patients (31.7%) underwent self-expandable valves, and 4 patients (1.6%) had mechanical-expandable valves. Malignancy was associated with worse short-term mortality at 30-days (HR 3.65, p = 0.054), while pulmonary disease and previous stroke were associated with worse long-term mortality at 5-years (HR 2.27, p = 0.012 and HR 2.02, p = 0.064). Worse all-cause mortality at 30-days, 1-year and 5-years were associated with high NT-Pro BNP levels (HR 1.04, p = 0.046; HR 1.05, p = 0.002 and HR 1.04, p < 0.001), the presence of peripheral arterial disease (PAD) (HR 4.32, p = 0.056; HR 4.48, p = 0.006 and HR 2.43, p = 0.023) and chronic kidney disease (CKD) (HR 6.19, p = 0.006; HR 6.77, p < 0.001 and HR 2.09, p = 0.008). Society of Thoracic Surgery (STS) score (HR 1.11, p = 0.001; HR 1.13, p < 0.001 and HR 1.12, p < 0.001) and Valve Academic Research Consortium (VARC) III endpoints of acute kidney injury (AKI) (HR 6.68, p = 0.047, HR 10.8, p < 0.001 and HR 6.99, p < 0.001), cardiogenic shock (HR 26.3, p < 0.001, HR 12.0, p < 0.001 and HR 4.29, p = 0.011) and structural complications (HR 40.3, p < 0.001, HR 18.1, p < 0.001 and HR 5.18, p = 0.008) were associated with worse all –cause mortality at time-points of 30-days, 1-year and 5-years respectively. On multivariate analyses adjusted for comorbidities and outcomes, STS score and structural complications were independent predictors of 30-day, 1-year, and 5-year all-cause mortality (HR 1.16; p = 0.003, HR 1.09, p = 0.003 and HR 1.10, p < 0.001) and (HR 62.7, p < 0.007; HR 18.9, p < 0.001 and HR 10.6, p = 0.001) respectively. Angiotensin converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) use was protective of survival within 1-year (HR 0.37, p = 0.022). Conclusions STS score and VARC III endpoints of structural complications were reliable predictors of all-cause mortality in Asian patients with TAVI. ACE inhibitor and ARB use was protective against mortality at 1-year.Cox regression analysesKaplan-Meier curves

Pregnancy protection in women of child-bearing age prescribed ACE inhibitors, ARBs or statins - A nationwide cohort study

Abstract Background Cardiometabolic disorders, including hypertension, type-2 diabetes, and hyperlipidemia are increasingly prevalent among younger people. Consequently, women of child-bearing age may be prescribed renin-angiotensin system (RAS) inhibitors and statins. Both angiotensin converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are known teratogens. Statins are considered possibly teratogenic. In Denmark, ACEIs and ARBs have a ‘Do not use’ recommendation in pregnancy while statins ‘Should not be used’ in pregnancy. Previous studies have reported widespread use of RAS inhibitors without concomitant contraception among women of child-bearing age. This study investigated the situation in Denmark. Purpose To examine prescribing patterns of RAS inhibitors and statins alongside use of concomitant contraception among women of child-bearing age in Denmark. Methods Using nationwide Danish registers, women aged 15–50 years initiating ACEIs, ARBs and statins during 1995–2021 were identified and use of concomitant contraception was evaluated. Contraception was categorized as oral pill, implant, intrauterine device (IUD), or non-use. The duration of protection was assumed to be 1 year for oral contraceptives, 2 years for implants and 4 years for IUDs. Where multiple types of contraceptives were retrieved by individual patients, they were categorized as taking the contraceptive retrieved most recently. Data on non-prescription contraceptives were unavailable, e.g., condoms. Women unable to conceive due to infertility were excluded. Results 79 547 women (median age: 44 years; [interquartile range (IQR): 39–47]) on ACEIs, 64 326 women (median age: 44 years [IQR: 38–48]) on ARBs, and 71 499 women (median age: 45 years [IQR: 40–48]) on statins were included (Figure 1). Correspondingly, 69.1%, 62.8%, and 73.5% were not on contraceptives when starting treatment. Among women prescribed contraception: 70.2%/56.2%/63.1% were on oral contraceptives, 25.3%/30.9%/26.6% had IUDs and 4.5%/12.9%/10.3% had implants, respectively (Figure 1). Younger patients aged 15–29 years were least likely to be unprotected with 41.8%/29.7%/33.4% being unprotected. Among women aged 25 to 35 years the percentage of unprotected women was 51.3%/41.1%/47.7%. Older patients were more likely to have IUDs. Conclusion Substantial numbers of women of child-bearing age were prescribed ACEIs, ARBs and statins from 1995–2021. Most were not prescribed contraceptives. The lack of prescribed pregnancy protection was prevalent even among the youngest women aged 15–29 years and women aged 25 to 35 years, who are the most likely to become pregnant—inferring a potential risk of teratogenic exposure during pregnancy (Figure 2). Subsequent studies should investigate the extent of exposure to ACEIs, ARBs, and statins during pregnancy and the impact of the exposure on pregnancy outcomes.Figure 1 Contraceptive useFigure 2 Study rationale

What does routinely-collected electronic health record data tell us about the use of heart failure medication among older people in Wales? Making progress but could do better

Abstract Background European Society of Cardiology 2021 guidelines recommend 4 pillars of treatment to reduce mortality for those with heart failure (HF) and reduced ejection fraction (HFrEF): pillar 1) angiotensin converting enzyme inhibitor (ACE-I)/angiotensin receptor blocker (ARB)/angiotensin receptor-neprilysin inhibitor (ARNI), pillar 2) beta-blocker (BB), pillar 3) mineralocorticoid receptor antagonist (MRA), pillar 4) sodium-glucose co-transporter 2 inhibitor (SGLT2i). When there is heart failure with preserved ejection fraction (HFpEF), guidelines recommend diuretics to alleviate congestion and treatment of risk factors such as hypertension and diabetes. Prior to 2021, United Kingdom guidelines did not include SGLT2i. Purpose To examine how HF treatment is recorded in routinely-collected electronic health record (EHR) data for older people in Wales, and to explore how that has changed since 2015. Methods We conducted a retrospective, population-level, observational study using linked anonymised EHR data in Wales (2015-22). 737,230 individuals were aged 65y+ in the study period (21.5% of population in 2022). Of these, 65,010 had a code for heart failure in their primary or secondary care records. We excluded 13,990 individuals with fewer than 12 months data pre- or post-diagnosis. We looked forward, from HF diagnosis, for codes associated with specific medications. Results The final cohort comprised 51,020 individuals aged 65y and over with a diagnosis of heart failure between 2015-2022. Incidence and prevalence of heart failure increased across the study period (1.4-1.5% and 8.5-9.1% respectively). Preceding cardiovascular diagnoses included hypertension (69.5%), atrial fibrillation (36.7%), myocardial infarction (30.5%), coronary artery disease (25.7%), and valve disease (17.7%). Diabetes (41.7%), chronic kidney disease (30.9%) and cancer (26.4%) were the most common comorbidities. The subtype of HF (HFrEF or HFpEF) was only evident in 5,850. Treatments recorded most often were loop diuretics, ACE-I, and BB (Table 1). SGLT2i codes increased in 2020/2021(Figure 1). At 10-12 months post diagnosis, the proportion with simultaneous pillar combinations was; 27.4% 1 + 2, 12.5% 1, 2 + 3, and only 2% 1, 2, 3 + 4. Conclusions In Wales, there is a need to improve the coding of HF subtype in primary care records. We suggest interpreting data with the assumption that approximately half of the cohort are likely to have HFrEF. While the cohort proportion on ACE-I or beta-blockers may be appropriate, the proportion with more than 1 simultaneous pillar of treatment recorded appears low. The use of SGLT2i in codes is increasing. These results are important in evaluating health service delivery and in establishing baseline data from which to monitor improvements.

Comorbidities, pharmacologic interventions, and mechanical interventions associated with mortality in isolated diastolic left heart failure: lessons from a national database.

Diastolic heart failure may be noted in paediatric patients with CHD, cardiomyopathy, or malignancies requiring chemotherapy, but the available data are scarce, and often derived from adult trials or based on theoretic or anecdotal evidence. Data between 2016 and 2021 were obtained from Pediatric Health Information System database. Patients <18 years of age with isolated diastolic heart failure admitted to ICU at some point during admission were included. They were divided into patients with and without inpatient mortality. Patients' demographics, comorbidities using ICD-10 codes, and pharmacologic interventions were also recorded. Univariate analysis was done in demographics, comorbidities, pharmacologic interventions, and mechanical interventions between admissions with and without mortality. Multivariable logistic regression was done for inpatient mortality and multivariable linear regression was done for total hospital length of stay in survivors. Isolated diastolic heart failure comprised 0.5% of critically ill paediatric patients. A total of 121 (5%) experienced mortality among the 2,273 admissions in the final analyses. Milrinone and angiotensin converting enzyme inhibitor were found to be associated with decreased mortality. Increasing age and diuretics were associated with decreased total hospital length of stay in survivors. In the cohort studied, isolated diastolic left heart failure has a 5% mortality. Several comorbidities and interventions are associated with increased mortality with milrinone and angiotensin converting enzyme inhibitors being associated with decreased risk of mortality. When only admissions with survival to discharge are considered, older age and diuretics are associated with lower total hospital length of stay.

Understanding the benefits of renin-angiotensin-aldosterone system inhibitors and influence of hyperkalaemia on their prescription: a UK survey of healthcare professionals' views and practice

Abstract Background Renin–angiotensin–aldosterone system inhibitors (RAASi) improve outcomes in heart failure with reduced ejection fraction (HFrEF) and they should be increased to the maximally tolerated dose. However, their use is often hindered by hyperkalaemia leading to discontinuation or down titration. Purpose Assess perceptions of primary and secondary healthcare professionals regarding benefits of RAASi according to indication and, in the context of developing hyperkalaemia, to identify barriers to optimal utilisation, and to explore options for improving management protocols, specifically in HFrEF. Methods An electronic survey was distributed in primary and secondary care setting in Hampshire, UK, to evaluate knowledge about benefits of RAASi, clinical response to varying level of potassium (K+), and decision-making using several clinical scenarios. Hyperkalaemia was graded into mild (serum K+ 5.5 – 5.9 mmol/L), moderate (serum K+ 6.0 – 6.4 mmol/L) or severe (serum K+ ≥ 6.5 mmol/L). Results Between November 2021 and January 2023, 300 questionnaires were completed by 274 (91%) physicians (varying grades of seniority), 22 (7%) non-medical prescribers, and 4 (1%) pharmacists. 80% were working in secondary care across different specialities (31 working in cardiology and 15 in nephrology). The majority were aware of prognostic benefit of angiotensin converting enzyme inhibitors (ACEi) in patients with HFrEF although this was lower for mineralocorticoid receptor antagonists (MRA) (Fig 1). Fewer than 2/3 of respondents were aware of impact of ACEi on symptoms. In the presence of mild hyperkalaemia, 75% and 88% of healthcare professionals would stop or reduce ACEi and MRA, respectively. In moderate or severe hyperkalaemia, this increased to 96% and 97%, respectively (Fig 2A-B). When considering the scenario of a patient with HFrEF who had ACEi stopped due to K+ 5.9 mmol/L, the potassium at which the responder would consider re-starting the ACEi ranged from 77% when potassium level &amp;lt; 5.5 mmol/L to 1% in moderate or severe hyperkalaemia (Fig 2C). 74% of healthcare professionals were familiar with local hyperkalaemia management protocol and 93% supported dedicated training on RAASi dose adjustment and hyperkalaemia management. Conclusion This survey, across a broad range of healthcare professionals, shows uncertainties around knowledge of benefits of RAASi in patients with HFrEF and there is sizeable variation in the prescribing response to degrees of hyperkalaemia. Given the voluntary nature of the survey, it is plausible that these data are biased towards individuals with greater understanding. Regardless, there is a need for continued education with a goal of improving patient-centred care.

Long-term continuation to pharmacological treatment for secondary prevention after a myocardial infarction: a register study

Abstract Background Pharmacological treatment for secondary prevention after acute myocardial infarction (MI) is crucial to prevent new events. Several studies report inconsistence and need for improvement of pharmacological treatment. Study follow-up is often less than 10 years and showing that continuation to drug treatment decreases with time. Objective To study long-term follow-up of nationally guideline recommended medical therapy (GDMT) for secondary prevention after a myocardial infarction. Method The study population consisted of individuals aged 18-84 years, who were hospitalized for a MI between January 2006 and December 2022 and were followed up to 16 years. The study subjects were identified through the National Inpatient Register and linked to the Prescribed Drug Register. Four classes of drugs were analyzed: antiplatelet/anticoagulant therapy, lowering therapy, betablockers and angiotensin converting enzyme inhibitors (ACEi)/angiotensin receptor blockers (ARB). Time-updated survival analyses were used to investigate the relationship between continuation of preventive pharmacological treatment and mortality and recurrent MI after an acute MI. Results A total number of 139 413 individuals (mean age 69.1±10.6) were included and 33.3% were female. At baseline 51.2% had hypertension, 21.5% diabetes mellitus and 15.2% heart failure. All prescriptions of GDMT were decreased significantly after hospitalization after MI and during first years and remained plateau (figure 1). During follow-up 55487 persons died (39.8%, event rate 5.81 per 100 person years [95% CI 5.76-5.86]). Medication with antiplatelets/anticoagulantia, ACEi/ARB and statins decreased risk of all cause-mortality and myocardial infarction [HR 0.83 [95% CI 0.79-0.86], p-value &amp;lt;0.001, HR 0,79 [95% CI 0.77-0.83], p-value &amp;lt;0.001, HR 0.70 [95% CI 0.67-0.73], p-value &amp;lt;0.001) respectively. Conclusion Pharmacological treatment as a part of secondary prevention remained greatly underutilized both shortly and during long-term after MI. Usage of antiplatelets or antigulantia, ACEi or ARB and statins decreased the risk of all-cause mortality and recurrent myocardial infarction.

Prognostic determinants in patients with heart failure with reduced ejection fraction after a first hospitalisation for acute heart failure. COMFE registry

Abstract Introduction The clinical characteristics and determinants for prognosis of patients with a first hospitalisation for heart failure (HF) with reduced left ventricular ejection fraction (LVEF &amp;lt;40%) are poor described and show heterogeneous results that need major investigation. Purpose The aim of our study was to identify the clinical characteristics, prognosis and their main determinants in a prospective registry of patients with HF and reduced LVEF with a first hospital admission for acute heart failure, prognosis and their main determinants in a prospective registry in these patients. Methods We carried out a prospective registry in 2 University Hospitals of patients admitted to cardiology department due to first-time HF hospitalisation with reduced LVEF. 231 admitted consecutively between March 2021 and September 2022 were included, with a mean follow-up of 381 days. Continuous variables were represented as median (interquartile range) and categorical variables as percentage %. A multivariate logistic regression was performed in which age, sex, comorbidities, treatment, rhythm at discharge and improvement in LVEF were included; and using the Wald method, the predictors of rehospitalization and/or death were identified. Data were analysed using SPSS v. 25.0. Results The main baseline characteristics are shown in Table 1. The population had a median age of 71 years, 75% were men, with a high prevalence of arterial hypertension (HBP) (69%) and hyperlipidemia (57%). Quadruple therapy (Na-Glucose cotransporter 2 inhibitor [SGLT2i], Beta-Blocker, mineralocorticoid receptor antagonist [MRA] and angiotensin receptor-neprilysin inhibitor [ARNI], angiotensin converting enzyme inhibitor [ACEi] or Angiotensin-II receptor blocker [ARB]) was achieved in 57% at discharge. The dynamics of NTproBNP was studied from admission to completed up-titration, observing an average reduction of 37% and 32% met the criteria for improved LVEF after. The etiology is described in Figure 1a, with ischemic heart disease being the most represented (31%). Multivariate Cox regression for the combined event of readmission/death from any cause showed that treatment with SGLT2i (OR 0,48 [CI 95%: 0,23-0,98 p:0,04]) and Beta-Blocker (OR 0,35 [CI 95%: 0,14-0,87 p:0,02]) at discharge and improved LVEF (OR 0,33 [CI 95%: 0,15-0,72 p:0,006]) were protective predictors against the event; but diabetes mellitus (DM) was a predictor of a worse prognosis (OR 2,9 [CI 95%: 1,52-5,5 p:0,001]) Fig. 1b. Conclusions Patients with a first admission for HF with reduced LVEF constitute a heterogeneous clinical group. Improvement in LVEF after drug up-titration and treatment with SGLT2i and Beta-blocker are independently associated with a better prognosis. Our findings may have implications for their clinical management.Table 1Figure 1

Sex-differences in prescription patterns of secondary prevention pharmacotherapy in patients with acute myocardial infarction: a 20-year perspective

Abstract Background Recent studies have demonstrated sex-related differences in secondary prevention pharmacotherapy in patients with acute myocardial infarction (AMI), although guidelines recommend the same preventive approach in both women and men. Purpose This study extends earlier work by examining temporal trends of prescribing practices of secondary prevention medications using contemporary data from a long-term period in Switzerland, with particular regard to sex inequalities. Methods For the purpose of this retrospective analysis of prospectively collected data in the Acute Myocardial Infarction in Switzerland (AMIS) Plus registry, optimal medical therapy (OMT) was defined as the combination of all five guideline-recommended medications in AMI at discharge: aspirin, P2Y12 inhibitors, lipid-lowering drugs, beta blockers, and angiotensin converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB). Uni- and multivariable logistic regression analyses were performed. Results A total of 34'612 patients (men n=25’913, 75%) hospitalised with AMI between 2003 and 2022 were included in the analysis. The mean age was 66±13 years and women were on average 7 years older than men. Despite having more comorbidities, women benefited less frequently from OMT than men (51% vs. 60%) across all age groups (all p&amp;lt;0.001), with the greatest gap occurring in patients &amp;lt;50 years of age. Within the 20-year study period, significant increases over time were observed in the singular prescription of all OMT components, except for beta blockers (p=0.2). This translated into a marked increase in OMT prescription irrespective of age and sex (from 36% to 60%), mainly due to greater prescription of dual antiplatelet therapy (DAPT, from 71% to 91%) and lipid-lowering drugs (LLD, from 69% to 93%). The sex-related gap in OMT disfavoring women showed a uctuating trend over the years (getting reduced from 14% in 2003 to 0.7% in 2016 to widen again to 12% in 2022) whereas there was a continuous narrowing over time regarding the combination of DAPT plus LLD, from 18% to 10% at the beginning and the end of the observation, respectively (Figure 1). In multivariable analysis, age (OR 0.99, 95%CI 0.98-0.99, p&amp;lt;0.001) and female sex (OR 0.90, 95%CI 0.85-0.95, p&amp;lt;0.001) were independent predictors of deficient OMT prescription, while the performance of percutaneous coronary intervention was identified as the strongest positive predictor favoring it (OR 4.85, 95%CI 4.49-5.24, p&amp;lt;0.001). Conclusion Although there has been a gradual increase in the prescription of OMT over time among both women and men, concerning sex disparities disfavoring women, and particularly young women, remained. Targeted programs to reduce sex-related differences in secondary prevention care are warranted.

Sodium-glucose co-transporter-2 inhibitors : a potential cardioprotective agent?

Abstract Background Sodium-glucose co-transporter-2 inhibitors (SGLT2i) are one of the cornerstones in the treatment of patients with heart failure (HF) , regardless the ejection fraction (EF) or the presence of diabetes mellitus (DM). Other types of medications used in the treatment of heart failure , like angiotensin converting enzyme inhibitors (ACEi) or beta-blockers (BB) have shown some degree of cardioprotection in high risk patients receiving cardiotoxic chemotherapy, but data on SGLT2i are very limited. Purpose To examine the possible differences in the development of anthracycline cardiotoxicity in diabetic patients receiving SGLT2i compared to those who don’t. Methods We retrospectively analysed the data from the oncological as well as hematological patients of our hospital. Group 1 (SGLT2) included patients with cancer who received anthracycline treatment and diabetes on treatment with SGLT2i. Group 2 (control) included patients with cancer who received anthracycline treatment and diabetes but with treatment other than SGLT2i. We recorded the basic demographic parameters, the development of cardiotoxicity (heart failure incidence, heart failure admissions, new cardiomyopathy [&amp;gt;10% decline in ejection fraction to &amp;lt;50%], and clinically significant arrhythmias) as well as the abnormal levels of troponin I (tnI) and natriuretic peptides (NTproBNP). Results Age, sex, ethnicity, cancer type, cancer stage, and other cardiac risk factors were similar between groups. The mean duration of the follow up was 2 years. In the SLT2 group were included 86 patients and in the control group 97. The rates of the cardiotoxicity events were recorded as follow : (SGLT2 vs control) Heart failure (7.4% vs 31.9%, p&amp;lt;0.01), heart failure admissions (3.4% vs 12.3%, p&amp;lt;0.05), new cardiomyopathy (6.1% vs 27.2%, p&amp;lt;0.05), arrhythmias (2.7% vs 24.3%, p&amp;lt;0.01), abnormal tnI levels (4.2% vs 14.7% , p&amp;lt; 0.01), abnormal NTproBNP levels (6.4% vs 30.9%, p&amp;lt;0.01) Conclusions SGLT2 inhibitors were associated with lower rate of cardiac events among patients with cancer and DM who were treated with anthracyclines. Further studies are needed in order to test the possible cardioprotective effects of SGLT2 inhibitors in patients at high cardiac risk treated with anthracyclines.
