Cardiovascular risk factors and kidney transplantation: a retrospective analysis

Abstract Introduction Cardiovascular disease (CVD) poses a significant risk to end-stage kidney disease (ESKD) patients and remains the leading cause of morbidity and mortality among kidney transplant (KT) recipients. With a global rise in ESKD patients dependent on dialysis, transplant programs face growing pressure to consider candidates with a greater burden of CVD for KT despite potential long-term risks. Enhancing pre-KT cardiac risk assessment is crucial to prevent cardiovascular complications post-transplant and meet the demand for KT globally. Purpose High-quality studies evaluating pre-KT cardiovascular risk factors in patients with ESKD are lacking. Our study aims to evaluate the association between pre-KT cardiovascular risk factors and the development of major adverse cardiac events (MACE) post-KT. Methods This retrospective cohort study of ESKD patients at a tertiary center consisted of consecutive patients referred for cardiovascular assessment prior to KT between January 2013 and January 2023. Clinical and demographic data prior to KT and outcomes 1-year post-KT were extracted. Patients who underwent multi-organ transplantation were excluded. The primary endpoint was MACE, defined as all-cause death, myocardial infarction (MI), ischemic stroke, coronary revascularization, heart failure requiring hospitalization, and cardiac resuscitation. Results A total of n=233 patients were referred for cardiac evaluation prior to KT. Of these, n=145 (62%) patients had a KT, n=69 (30%) patients died pre-KT, and n=19 (8%) patients were removed from the transplant program. Of the n=143 KT recipients that met our inclusion criteria, 122 (85%) were free of MACE, while 21 (15%) met the primary endpoint in the year following KT. Patients with MACE were significantly older (mean age = 65 vs. mean age = 59, p < 0.001), and more likely to have coronary artery disease (85.7% vs. 50.8%, p = 0.01), cardiomyopathy (42.9% vs. 17.2%, p = 0.04), smoking history (71.4% vs. 46.7%, p = 0.04), and diabetes (85.7% vs. 49.2%, p = 0.02). Furthermore, deceased donor KT was associated with a greater likelihood of MACE (85.0% vs. 57.5%, p = 0.02) compared to living donor recipients. There were no significant differences with respect to left ventricular ejection fraction, diagnosis of heart failure, or prior MI between MACE and non-MACE groups (p > 0.17 for all). Conclusion Among pre-KT patients with CVD, there is a high mortality rate (30%) prior to KT. Following a successful KT, 15% of patients experienced MACE within 1-year. Our findings underscore the urgency of developing strategies to facilitate timely kidney transplantation, particularly in light of the anticipated rise in demand for kidney transplants. The elevated incidence of major adverse events in the year following a successful KT emphasizes the necessity of collaborative care by cardiologists and nephrologists for these patients, and the need for further studies to improve long-term outcomes.

The effects of conjugated linoleic acid supplementation on cardiovascular risk factors in patients at risk of cardiovascular disease: A GRADE-assessed systematic review and dose-response meta-analysis.

The present systematic review and meta-analysis sought to evaluate the effects of conjugated linoleic acid (CLA) supplementation on cardiovascular risk factors in patients at risk of CVD. Relevant studies were obtained by searching the PubMed, SCOPUS and Web of Science databases (from inception to January 2023). Weighted mean differences (WMD) and 95% CI were pooled using a random-effects model. Heterogeneity, sensitivity analysis and publication bias were reported using standard methods. A pooled analysis of 14 randomised controlled trials (RCT) with 17 effect sizes revealed that CLA supplementation led to significant reductions in body weight (WMD: -0·72 kg, 95% CI: -1·11, -0·33, P < 0·001), BMI (WMD: -0·22 kg/m2, 95% CI: -0·44, -0·00, P = 0·037) and body fat percentage (BFP) (WMD: -1·32 %, 95% CI: -2·24, -0·40, P = 0·005). However, there was no effect on lipid profile and blood pressure in comparison with the control group. In conclusion, CLA supplementation may yield a small but significant beneficial effect on anthropometric indices in patients at risk of CVD. Moreover, CLA seems not to have adverse effects on lipid profiles and blood pressure in patients at risk of CVD. It should be noted that the favourable effects of CLA supplementation on anthropometric variables were small and may not reach clinical importance.

Pituitary Apoplexy: Comorbidities, Management and Outcomes. A Spanish Observational Multicenter Study

Abstract Background Pituitary apoplexy (PA) is the paradigm of endocrine and neurosurgical emergency. Objective To evaluate the comorbidities, risk factors, clinical presentation, pituitary apoplexy score (PAS) and the outcomes of surgical vs. conservative management of PA in Spain. Methods Spanish multicenter, observational study of 301 patients with acute PA. Statistical analyses compared risk factors, clinical presentation and outcomes between the surgical and conservative treatment groups, adjusting for potential confounders. The prevalence of cardiovascular risk factors in patients with pituitary apoplexy was compared with the Spanish population and with patients with non-functioning pituitary adenomas. Results Median age was 59.3 years, 201 (66.8%) were men and non-functioning adenomas (77.9%) were the most common tumor type. The prevalence of diabetes (20.3% vs 13.9%, p&amp;lt;0.01), hypertension (48.8% vs 33.4%, p&amp;lt;0.01) and dyslipidemia (44.2% vs 23.3%, p&amp;lt;0.01), exceeded the Spanish age-adjusted population prevalence. Overall, 209 (69.4%) underwent surgery and 92 (30.6%) received conservative treatment. Surgical patients had larger tumors (26.2 vs 21.0 mm, p&amp;lt;0.01), chiasmal compression more frequently (77.2% vs 53.4%, p&amp;lt;0.01) and higher values of PAS. In the follow-up, while there were no statistically significant differences in anterior pituitary hormonal deficits between treatments, permanent vasopressin deficiency was more frequent after surgery (14.8% vs 3.3%, p&amp;lt;0.01). Conclusion There is a high burden of cardiovascular risk factors among patients with PA suggesting that metabolic factors may play a potential role in the development of PA. This underscores the need for comprehensive management of these conditions in addition to treating the apoplexy itself in this population. Surgical management has a relevant place in PA approach mainly in patients with higher PAS. However, it leads permanent vasopressin deficit more frequently than conservative approach.

Prevalence of risk factors in cardiovascular patients in a Caribbean country: Age and sex differences

Background/objectivesCardiovascular disease (CVD) is the leading cause of death worldwide, however little is known about the prevalence of risk factors in the Caribbean country of Trinidad and Tobago. This study investigates the prevalence of major cardiovascular risk factors in patients with CVD in Trinidad and Tobago between two age groups – <60 years and ≥60 years – and determines if the prevalence differed with sex. MethodsMedical records of 151 patients with CVD admitted to a private hospital in Trinidad and Tobago between January 2015 and March 2021 were analyzed. Patients were divided by sex, and into two age groups: <60 years (young) and ≥60 years (elderly). Chi-squared and Mann-Whitney U tests were used to analyze five major cardiovascular risk factors: hypertension, diabetes, smoking, hypercholesterolaemia, and family history of coronary heart disease (CHD). ResultsIt was found that the prevalence of hypertension was higher in the elderly group, while smoking, hypercholesterolaemia and family history of CHD were more common in males than in females. The prevalence of different risk factors varied with sex in the age groups: diabetes and family history of CHD in the <60 age group, and smoking and hypercholesterolaemia in the ≥60 age group. These risk factors were more prevalent in males than in females within the age groups. Additionally, the mean age of females in the ≥60 age group was found to be greater than that of males in the same age group. ConclusionsAge and sex differences were observed in the prevalence of major CVD risk factors, which may influence the management of CVD in Trinidad and Tobago. Intervention strategies, such as health education and counselling programmes that are age- and sex-specific, are recommended.

Evaluation of the relationship between dietary acid load and cardiovascular risk factors in patients with type 2 diabetes: a case-control study.

Diets high in dietary acid load are thought to be associated with metabolic diseases. However, the number of studies examining the relationship between dietary acid load and metabolic diseases in Turkey is insufficient. The aim of this study was to investigate the relationship between cardiovascular disease risk factors and dietary acid load in individuals with type 2 diabetes. In this case-control study, 51 participants aged 30-65 years with type 2 diabetes and 59 participants in the control group were included. Blood pressure and biochemical findings were measured. Anthropometric measurements and body composition measurements were made. Dietary intake was assessed using a 3-day (1 day on weekends, 2 days on weekdays) food consumption record. Dietary acid load scores, including potential renal acid load (PRAL) and net endogenous acid production (NEAP), were calculated based on dietary intake. NEAP and PRAL scores were categorized as low and high according to the median value. Smoking status, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), trigylceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL), waist-hip ratio (WHR), waist-to- height ratio (WtHR), hemoglobin and fat mass (%) were evaluated as cardiovascular risk factors. The cut-off values of PRAL and NEAP were 3.61 and 44.78 mEq/d, respectively. After adjustment for various covariates, a significant positive association between PRAL and TG levels was observed in the diabetic group [odds ratio (OR), 5.98; 95% CI, 1.45-24.67; p = 0.013]. In contrast, a negative association was found between PRAL and SBP in the control group [odds ratio (OR), 0.21; 95% CI, 0.05-0.83; p = 0.026]. However, these associations were not observed for NEAP values in either group. A higher PRAL value was consistently associated with higher TG level, but other cardiovascular risk factors were not. More longitudinal and interventional studies are needed to better establish a causal effect between dietary acid load and cardiovascular risk factors in individuals with diabetes.

Relationship between Oral Lichen Planus and Cardiovascular Disease of Atherosclerotic Origin: Systematic Review and Meta-Analysis.

Background/Objectives: Oral lichen planus (OLP) is a chronic inflammatory autoimmune disease of the oral mucosa that affects between 0.5% and 2% of the general population. In the last decade, several studies have associated cardiovascular diseases (CVDs) with some inflammatory skin diseases such as oral lichen planus, demonstrating the presence of dyslipidemia in these pathologies. The objective of this work is to review whether patients with OLP show higher dyslipidemia and CRP levels compared to a healthy control population without OLP. Methods: Searches were carried out in Medline, Scopus, and Cochrane. The studies had to perform a histopathological diagnosis for OLP and the patients could not take any medication to treat this disorder. Non-lichenoid reactions were included. Results: After an initial search that provided us with 254 papers, this number was reduced to 10 articles after a detailed evaluation. All of them were case-control studies that compared the presence of analytical cardiovascular risk factors in patients affected by OLP and in healthy subjects. Conclusions: There is no scientific evidence of the possible association between OLP and CVDs. The only association we can prove is the one between OPL and CVD risk factors, especially those related to the lipid profile. More studies are needed in order to evaluate this relationship in patients diagnosed with CVDs.

High prevalence of erectile dysfunction in male patients with acute stroke was associated with age but not to modifiable cardiovascular risk factors

BackgroundErectile dysfunction (ED) and stroke share common risk factors, and symptoms of ED often precede the development of clinical cardiovascular disease (CVD). However, little is known about how ED is...

Adherence to optimal medical therapy and control of cardiovascular risk factors in patients after ST elevation myocardial infarction in Mexico.

In developing countries, there is a notable scarcity of real-world data on adherence to optimal medical therapy (OMT) and its correlation with major cardiovascular adverse events (MACEs) after ST-elevation myocardial infarction (STEMI). Our study focuses on addressing this gap by evaluating adherence to OMT, examining its influence on the risk of MACEs after STEMI, and assessing subsequent cardiovascular risk factor control in Mexico. We conducted a prospective observational study of post-STEMI patients after hospital discharge. Adherence to treatment was assessed over a median of 683 days (interquartile range: 478-833) using the Simplified Medication Adherence Questionnaire (SMAQ). Patients were followed up for 4.5 years to monitor MACEs (cardiovascular death, cardiogenic shock, recurrent myocardial infarction, and heart failure). We included 349 patients with a mean age of 58.08 years (±10.9), predominantly male (89.9%). Hypertension (42.4%), smoking (34.3%), type 2 diabetes mellitus (31.2%), obesity (22.92%), and dyslipidemia (21.4%) were highly prevalent. Adherence to OMT per SMAQ was 44.7%. The baseline clinical characteristics of adherent and non-adherent patients did not significantly differ. OMT prescription rates were as follows: acetylsalicylic acid, 91.1%; P2Y12 inhibitors, 76.5%; and high-intensity statins, 86.6%. While non-adherent patients had a numerically higher rate of MACEs (73 vs. 49 first events), there was no statistically significant difference (hazard ratio 1.30, 95% confidence interval 0.90-1.88). In this real-world study of patients after STEMI, we observed low adherence to OMT, a low proportion of global cardiovascular risk factor control, and a numerically higher incidence of recurrent major adverse cardiovascular events in non-adherent patients. Strategies to improve adherence to OMT and risk factor control are needed.

Impact of very low carbohydrate ketogenic diets on cardiovascular risk factors among patients with type 2 diabetes; GRADE-assessed systematic review and meta-analysis of clinical trials

ObjectiveThis study was designed to evaluate the impact of VLCKD on cardiovascular risk factors in patients with T2DM.MethodsUntil March 2024, extensive searches were conducted on PubMed, Scopus, Web of Science, Embase, and other relevant databases. The purpose was to identify clinical trials examining the impact of VLCKD on glycemic control, lipid profile, and blood pressure. The GRADE (Grading of Recommendations Assessment, Development, and Evaluation) method was used to assess the evidence’s degree of certainty.ResultsOur initial search found a total of 2568 records and finally 29 trials were included in final analysis. Our results showed that adherence from VLCKD led to significant reduction in fasting blood sugar (WMD= -11.68 mg/dl; 95% CI: -18.79, -4.56; P = 0.001), HbA1c (WMD= -0.29; 95% CI: -0.44, -0.14; P < 0.001), HOMA-IR(WMD= -0.71; 95% CI: -1.14, -0.29; P = 0.001), insulin (WMD= -1.45; 95% CI: -2.54, -0.36; P = 0.009), triglyceride (WMD= -17.95; 95% CI: -26.82, -9.07; P < 0.001), systolic blood pressure (WMD= -2.85, 95% CI: -4.99, -0.71; P = 0.009) and diastolic blood pressure (WMD= -1.40; 95% CI: -2.66, -0.13; P = 0.03). We also found a significant increase in high-density lipoprotein (HDL) level after adherence from VLCKD diet (WMD = 3.93, 95% CI: 2.03, 5.84; P = 0.000). We couldn’t find any significant differences between groups in term of LDL and total cholesterol levels.ConclusionPeople following a VLCKD experience a more significant improvement in cardiovascular risk factors when compared to individuals on control diets.

Gastric Bypass vs Diet and Cardiovascular Risk Factors

Roux-en-Y gastric bypass (RYGB) is associated with reduced cardiovascular (CV) risk factors, morbidity, and mortality. Whether these effects are specifically induced by the surgical procedure or the weight loss is unclear. To compare 6-week changes in CV risk factors in patients with obesity undergoing matching caloric restriction and weight loss by RYGB or a very low-energy diet (VLED). This nonrandomized controlled study (Impact of Body Weight, Low Calorie Diet, and Gastric Bypass on Drug Bioavailability, Cardiovascular Risk Factors, and Metabolic Biomarkers [COCKTAIL]) was conducted at a tertiary care obesity center in Norway. Participants were individuals with severe obesity preparing for RYGB or a VLED. Recruitment began February 26, 2015; the first patient visit was on March 18, 2015, and the last patient visit (9-week follow-up) was on August 9, 2017. Data were analyzed from April 30, 2021, through June 29, 2023. VLED alone for 6 weeks or VLED for 6 weeks after RYGB; both interventions were preceded by 3-week LED. Between-group comparisons of 6-week changes in CV risk factors. Among 78 patients included in the analyses, the mean (SD) age was 47.5 (9.7) years; 51 (65%) were women, and 27 (35%) were men. Except for a slightly higher mean (SD) body mass index of 44.5 (6.2) in the RYGB group (n = 41) vs 41.9 (5.4) in the VLED group (n = 37), baseline demographic and clinical characteristics were similar between groups. Major atherogenic blood lipids (low-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol, apolipoprotein B, lipoprotein[a]) were reduced after RYGB in comparison with VLED despite a similar fat mass loss. Mean between-group differences were -17.7 mg/dL (95% CI, -27.9 to -7.5), -17.4 mg/dL (95% CI, -29.8 to -5.0) mg/dL, -9.94 mg/dL (95% CI, -15.75 to -4.14), and geometric mean ratio was 0.55 U/L (95% CI, 0.42 to 0.72), respectively. Changes in glycemic control and blood pressure were similar between groups. This study found that clinically meaningful reductions in major atherogenic blood lipids were demonstrated after RYGB, indicating that RYGB may reduce CV risk independent of weight loss.

Cardiovascular Risk Factors and Disparities in Management of Embolic Stroke: A Western Sydney Perspective

Ischaemic stroke remains one of the leading causes of death and disability worldwide. The population of Western Sydney has a unique demographic with lower socioeconomic status and a culturally and linguistically diverse population. This study aims to investigate the demographics and cardiovascular risk factors of patients in Western Sydney, focusing on the prevalence and profile of cardioembolic (CE) strokes and embolic strokes of undetermined source (ESUS). Prospective data were collected in 463 patients with ischaemic stroke presenting to a tertiary centre in Western Sydney, who underwent predischarge transthoracic echocardiography. Patients with haemorrhagic strokes or unclear stroke diagnosis were excluded. Analysis of stroke subtype (CE, ESUS, or non-embolic) and clinical characteristics was performed based on age, gender, and prior atrial fibrillation (AF) prevalence. Of the 463 patients, 147 (32%) had CE strokes, and 147 (32%) had ESUS. Cardioembolic (CE) strokes were associated with older age (≥65 years) and a history of congestive cardiac failure. Older patients had higher rates of hypertension, ischaemic heart disease, AF, and congestive heart failure. History of AF was present in 67 patients (14.5%); however, only 51% received anticoagulation before admission despite a low bleeding risk. The transthoracic echocardiography characteristics of ESUS/non-embolic strokes differed from those of CE strokes; 20% of patients with ESUS had an enlarged left atrium, suggesting a subset of patients with ESUS with a left atrial myopathy. Patients with ischaemic stroke in Western Sydney have a high prevalence of cardiovascular risk factors which were often undertreated. Half of the patients with prior AF did not receive anticoagulation despite low bleeding risk, indicating a gap in optimal stroke prevention. There were distinct echocardiographic characteristics among stroke subtypes. Further analysis of left atrium parameters may provide greater insights into the pathogenesis and prevention of embolic strokes.

Coronary Stenosis in a Patient Under Pazopanib Therapy: A Case Study

Tyrosine kinase inhibitors have transformed therapeutic approaches to cancer, marking a major advance in oncology. This article presents the clinical case of a 59-year-old moroccan patient with metastatic clear cell kidney cancer treated with pazopanib, who developed a cardiac vascular accident through coronary stenosis after 24 months of treatment with pazopanib. The main objective of this article is to illustrate the side effects of anti-angiogenic drugs and the crucial importance of monitoring these toxicities, particularly those of vascular origin, in order to prevent serious complications that could compromise the prognosis of a patient, regardless of the cancer disease itself. This case highlights the need for regular assessment of cardiovascular risk factors in patients receiving treatment with pazopanib, as well as increased vigilance for the appearance of signs or symptoms suggesting hematological or hepatic toxicities. Early and appropriate management of toxicities is essential to optimize the safety and effectiveness of renal cancer treatment with pazopanib, while preserving the patient's cardiovascular health.

Managing cardiovascular risk factors in patients with chronic kidney disease: pharmacological and non-pharmacological interventions in the Copenhagen CKD Cohort.

Although cardiovascular morbidity and mortality are substantial in patients with chronic kidney disease (CKD), guideline-directed treatment of cardiovascular risk factors remains a challenge. Observational, cross-sectional study including patients aged 30-75 years with CKD stage 1-5 without kidney replacement therapy from a tertiary hospital outpatient clinic. Data were obtained through patient interview, clinical examination, biochemical work-up, and evaluation of medical records and prescription redemptions. Guideline-directed treatment was evaluated as pharmacological interventions: antihypertensive and lipid-lowering therapy including adverse effects and adherence estimated as medication possession ratio (MPR); and non-pharmacological interventions: smoking status, alcohol consumption, body mass index (BMI), and physical activity. The cohort comprised 741 patients, mean age 58 years, 61.4% male, 50.6% CKD stage 3, 61.0% office blood pressure ≤140/90mmHg. Antihypertensives were prescribed to 87.0%, median number of medications 2 (IQR 1;3), 70.1% received renin-angiotensin system inhibition, 25.9% reported adverse effects. Non-adherence (MPR<80%) was present in 23.4% and associated with elevated blood pressure (OR 1.53 (95% CI 1.03;2.27)) and increased urinary albumin excretion, P<0.001. Lipid-lowering treatment was prescribed to 54.0% of eligible patients, 11.1% reported adverse effects, and 28.5% were non-adherent, which was associated with higher LDL cholesterol, P=0.036. Overall, 19.2% were current smokers, 16.7% overconsumed alcohol according to Danish health authority recommendations 69.3% had BMI≥25kg/m2, and 38.3% were physically active <4 hours/week. Among patients prescribed antihypertensives, 51.9% reported having received advice on non-pharmacological interventions. Improved management of cardiovascular risk in patients with CKD entails intensified medical treatment and increased focus on patient adherence and non-pharmacological interventions.

Prevalence and target attainment of traditional cardiovascular risk factors in patients with systemic lupus erythematosus: a cross-sectional study including 3401 individuals from 24 countries

Systemic lupus erythematosus (SLE) is characterised by increased cardiovascular morbidity and mortality risk. We aimed to examine the prevalence of traditional cardiovascular risk factors and their control in an international survey of patients with systemic lupus erythematosus. In this multicentre, cross-sectional study, cardiovascular risk factor data from medical files of adult patients (aged ≥18) with SLE followed between Jan 1, 2015, and Jan 1, 2020, were collected from 24 countries, across five continents. We assessed the prevalence and target attainment of cardiovascular risk factors and examined potential differences by country income level and antiphospholipid syndrome coexistence. We used the Systemic Coronary Risk Evaluation algorithm for cardiovascular risk estimation, and the European Society of Cardiology guidelines for assessing cardiovascular risk factor target attainment. People with lived experience were not involved in the research or writing process. 3401 patients with SLE were included in the study. The median age was 43·0 years (IQR 33-54), 3047 (89·7%) of 3396 patients were women, 349 (10.3%) were men, and 1629 (48·1%) of 3390 were White. 556 (20·7%) of 2681 patients had concomitant antiphospholipid syndrome. We found a high cardiovascular risk factor prevalence (hypertension 1210 [35·6%] of 3398 patients, obesity 751 [23·7%] of 3169 patients, and hyperlipidaemia 650 [19·8%] of 3279 patients), and suboptimal control of modifiable cardiovascular risk factors (blood pressure [target of <130/80 mm Hg], BMI, and lipids) in the entire SLE group. Higher prevalence of cardiovascular risk factors but a better blood pressure (target of <130/80 mm Hg; 54·9% [1170 of 2132 patients] vs 46·8% [519 of 1109 patients]; p<0·0001), and lipid control (75·0% [895 of 1194 patients] vs 51·4% [386 of 751 patients], p<0·0001 for high-density lipoprotein [HDL]; 66·4% [769 of 1158 patients] vs 60·8% [453 of 745 patients], p=0·013 for non-HDL; 80·9% [1017 of 1257 patients] vs 61·4% [486 of 792 patients], p<0·0001 for triglycerides]) was observed in patients from high-income versus those from middle-income countries. Patients with SLE with antiphospholipid syndrome had a higher prevalence of modifiable cardiovascular risk factors, and significantly lower attainment of BMI and lipid targets (for low-density lipoprotein and non-HDL) than patients with SLE without antiphospholipid syndrome. High prevalence and inadequate cardiovascular risk factor control were observed in a large multicentre and multiethnic SLE cohort, especially among patients from middle-income compared with high-income countries and among those with coexistent antiphospholipid syndrome. Increased awareness of cardiovascular disease risk in SLE, especially in the above subgroups, is urgently warranted. None.

Inflammation in ischemic stroke patients with type 2 diabetes – Part II: Potential therapeutic targets

Stroke is the leading cause of disability and the second leading cause of death worldwide. Diabetes mellitus is an important independent cardiovascular risk factor in patients, regardless of age, smoking habit, and hypertension. Approximately one-third of first-time ischemic stroke patients have diabetes. Inflammation is among the most important pathological mechanisms in atheroma formation, the damage cascades of the acute phase, as well as during the subacute and chronic phases after stroke. Diabetes, as a common risk factor for stroke, is often present for a long time before a stroke occurs, causing low-grade inflammation, and disrupting the proper functioning of the neurovascular units. These proinflammatory processes and maladaptive immune mechanisms are further accelerated after cerebral ischemia and worsen the stroke outcome in diabetic patients. Clinical treatments for ischemic stroke are currently focused on restoring cerebral blood flow (reperfusion) in the acute phase, including thrombolysis and mechanical thrombectomy, which are not applicable to patients that fall outside of the treatment window and/or without large-vessel occlusion. There are few approved treatments targeting cellular injury caused by inflammation. There are even fewer data on effective treatment for diabetic stroke targeting inflammation. This paper presents the second part of a review focusing on the potential therapeutic targets in stroke patients with type 2 diabetes.

Inflammation in ischemic stroke patients with type 2 diabetes – Part I: Atherosclerosis formation, acute ischemia, post-stroke infection, and long-term sequelae

How much protected? Assessment of cardiovascular risk factors in patients with previous cardiovascular events admitted for acute coronary syndrome

How much protected? Assessment of cardiovascular risk factors in patients with previous cardiovascular events admitted for acute coronary syndrome

Lipid Profiles and Atrial Fibrillation in Ischemic Stroke Patients Treated with Thrombectomy: Experience from a Tertiary Italian Stroke Hospital.

To assess acute lipid profiles, atrial fibrillation and other cardiovascular risk factors in patients undergoing treatments by thrombectomy (EVT) with acute ischemic stroke (AIS). We performed a retrospective analysis of the lipid profile and vascular risk factor in 1639 consecutive patients with acute ischemic stroke between January 2016 and December 2021. To assess lipid profiles, laboratory tests, including total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG), were obtained the day after admission. We also examined the association between lipid profile, AF and EVT in multivariate logistic regression analysis. Median age of patients was 74 years, 54.9% were males (95% CI 52.5-57.4%), and 26.8% (95% CI, 24.7-29.0%) had AF. EVT patients (n = 370; 22.57 %; 95% CI, 20.6-24.7) showed no difference in age (median 73 years (IQR; 63-80) versus 74 years (IQR; 63-82)), HbA1c levels (median 5.8 (IQR; 5.4-6.2) versus 5.9 (IQR; 5.4-6.4)), TG/HDL ratio (median 2.40 (IQR; 1.65-3.48) versus 2.51 (IQR; 1.73-3.64)), diabetes (OR 0.82; 95% CI 0.61 to 1.08), hypertension (OR 0.87; 95% CI 0.68 to 1.12) and obesity (OR 1.06; 95% CI 0.78 to 1.42) compared to non-EVT patients. Conversely, EVT patients showed lower levels of TC (160 mg/dl (IQR; 139- 187) versus 173 mg/dl (IQR; 148-202); p <0.001), LDL-C (105 mg/dl (IQR; 80-133) versus 113 mg/dl (IQR; 88-142); p <0.01), TG (98 mg/dl (IQR; 76-126) versus 107 mg/dl (IQR; 85-139); p <0.001), non-HDL-C (117 mg/dl (IQR; 94-145) versus 127 mg/dl (IQR; 103-154); p <0.001), HC (8.3 mmol/l (IQR; 6-11) versus 10 mmol/l (IQR; 7.3-13.5); p <0.001) than non-EVT patients. Multivariate logistic regression analysis showed an independent association of EVT with TC (OR 0.99, 95% CI 0.98-0.99), AF (OR 1.79, 95% CI 1.34-2.38), age (OR 0.98, 95% CI 0.96-0.99), and NIHSS (OR 1.17, 95% CI 0.14-1.19). Total cholesterol and all cholesterol-related measures were significantly lower in patients undergoing thrombectomy than in other stroke patients. Conversely, we found that AF was significantly high in patients with EVT, suggesting that hypercholesterolemia could be mainly linked to small-vessel occlusion stroke while large vessel occlusion (LVO) stroke could show different causes. AIS patients may have different pathogenesis and their understanding may improve the discovery of specific and tailored preventive treatments.

Liver fibrosis is associated with left ventricular remodeling: insight into the liver-heart axis

ObjectiveIn nonalcoholic fatty liver disease (NAFLD), liver fibrosis is the strongest predictor of adverse outcomes. We sought to investigate the relationship between liver fibrosis and cardiac remodeling in participants from the general population using magnetic resonance imaging (MRI), as well as explore potential mechanistic pathways by analyzing circulating cardiovascular biomarkers.MethodsIn this cross-sectional study, we prospectively included participants with type 2 diabetes and individually matched controls from the SCAPIS (Swedish CArdioPulmonary bioImage Study) cohort in Linköping, Sweden. Between November 2017 and July 2018, participants underwent MRI at 1.5 Tesla for quantification of liver proton density fat fraction (spectroscopy), liver fibrosis (stiffness from elastography), left ventricular (LV) structure and function, as well as myocardial native T1 mapping. We analyzed 278 circulating cardiovascular biomarkers using a Bayesian statistical approach.ResultsIn total, 92 participants were enrolled (mean age 59.5 ± 4.6 years, 32 women). The mean liver stiffness was 2.1 ± 0.4 kPa. 53 participants displayed hepatic steatosis. LV concentricity increased across quartiles of liver stiffness. Neither liver fat nor liver stiffness displayed any relationships to myocardial tissue characteristics (native T1). In a regression analysis, liver stiffness was related to increased LV concentricity. This association was independent of diabetes and liver fat (Beta = 0.26, p = 0.0053), but was attenuated (Beta = 0.17, p = 0.077) when also adjusting for circulating levels of interleukin-1 receptor type 2.ConclusionMRI reveals that liver fibrosis is associated to structural LV remodeling, in terms of increased concentricity, in participants from the general population. This relationship could involve the interleukin-1 signaling.Clinical relevance statementLiver fibrosis may be considered a cardiovascular risk factor in patients without cirrhosis. Further research on the mechanisms that link liver fibrosis to left ventricular concentricity may reveal potential therapeutic targets in patients with non-alcoholic fatty liver disease (NAFLD).Key PointsPreviously, studies on liver fibrosis and cardiac remodeling have focused on advanced stages of liver fibrosis.Liver fibrosis is associated with left ventricular (LV) concentricity and may relate to interleukin-1 receptor type 2.Interleukin-1 signaling is a potential mechanistic interlink between early liver fibrosis and LV remodeling.

#1299 The SGLT2 inhibitor canagliflozin, but not dapagliflozin or empagliflozin, ameliorates vascular calcification in a mouse model of nephrocalcinosis

Abstract Background and Aims Vascular calcification, defined as the abnormal deposition of minerals in blood vessels, is a major cardiovascular risk factor in patients with kidney failure. Sodium-glucose co-transporter 2 (SGLT2) inhibitors, commonly known as gliflozins, are a class of pharmaceutical compounds that have revolutionised the therapeutic management of type 2 diabetes. These drugs target the SGLT2 transporter, increasing glucose elimination through the urine, effectively lowering hyperglycaemia. In addition to their effect on blood sugar control, SGLT2 inhibitors have recently gained attention for potential cardiovascular benefits in patients with type 2 diabetes, chronic kidney disease (CKD) or established cardiovascular disease. Initially thought to be secondary to the promotion of urinary sodium and glucose excretion and weight loss, recent studies have also reported direct effects of gliflozins on the vascular compartment. Given the significant impact of vascular calcification on cardiovascular health in patients with kidney failure, the aim of this study was to investigate whether the three different SGLT2 inhibitors (canagliflozin, empagliflozin and dapagliflozin) could reduce the development of vascular calcification. Method Western blotting was used to investigate SGLT2 expression in mouse and human vascular smooth muscle cells (VSMC) and vascular explants. Human and mouse aortic VSMC and mouse aorta and human epigastric and iliac artery segments were treated with calcification medium supplemented with 1 or 5 µM of gliflozins. A nephrocalcinosis mouse model consisting of 2 weeks of high phosphorus diet (2%) in female DBA/2 mice was used in in vivo experiments. The animals were treated daily with the different gliflozins (3 mg/kg/j) by oral gavage. Calcium deposits were quantified using a quantitative colorimetric assay and alizarin red staining, blood and urine glucose levels were measured using a quantitative colorimetric assay and glomerular filtration rate (GFR) was measured using sinistrin-FITC excretion. Results We observed that SGLT2 is expressed in mouse and human vessels and vascular smooth muscle cells (VSMC). Treatment with canagliflozin, but not dapagliflozin or empagliflozin, reduced calcification in vitro, in human and mouse VSMC and ex vivo, in mouse aorta and human epigastric and iliac artery segments. The high phosphorus diet in mice led to nephrocalcinosis associated with impaired renal function as well as vascular calcification development in the aorta. In this model, although all 3 gliflozins showed efficacy in increasing urinary glucose excretion, blood glucose levels were not affected by gliflozins and renal function was not improved. However, canagliflozin, but not dapagliflozin or empagliflozin, significantly reduced vascular calcification in this nephrocalcinosis mouse model. Conclusion Our study demonstrated that canagliflozin reduces vascular calcification development, highlighting its potential as a therapeutic strategy. This protective effect was found to be drug-dependent and not class-dependent, as the other two SGLT2 inhibitors, dapagliflozin and empagliflozin, showed no significant effect on vascular calcification. Further studies are needed to understand the mechanisms and pathways involved and to determine whether the differential effect of the gliflozins is due to an off-target action of canagliflozin on other SGLT transporters.
