Pharmacotherapy as an Augmentation to Bariatric Surgery for Obesity.

A global obesity pandemic is one of the most significant health threats worldwide owing to its close association with numerous comorbidities such as type 2 diabetes mellitus, arterial hypertension, dyslipidemia, heart failure, cancer and many others. Obesity and its comorbidities lead to a higher rate of cardiovascular complications, heart failure and increased cardiovascular and overall mortality. Bariatric surgery is at present the most potent therapy for obesity, inducing a significant weight loss in the majority of patients. In the long-term, a substantial proportion of patients after bariatric surgery experience a gradual weight regain that may, in some, reach up to a presurgical body weight. As a result, anti-obesity pharmacotherapy may be needed in some patients after bariatric surgery to prevent the weight regain or to further potentiate weight loss. This article provides an overview of the use of anti-obesity medications as an augmentation to bariatric surgery for obesity. Despite relatively limited published data, it can be concluded that anti-obesity medication can serve as an effective adjunct therapy to bariatric surgery to help boost post-bariatric weight loss or prevent weight regain.

#2061 Perirenal fat thickness as a potential marker for cardiovascular risk in chronic kidney disease: the influence of vitamin D analogs

Abstract Background and Aims Patients with CKD show high cardiovascular complication rates. There are classical cardiovascular risk factors, such as obesity, dyslipidemia, and diabetes; however, other cardiovascular disease risk factors are associated with mineral metabolism disorders (phosphorus, hyperparathyroidism, etc.) typically appear in CKD. Due to their pleiotropic effects, vitamin D analogs, such as cholecalciferol, calcitriol, or paricalcitol, have proven effective in controlling bone mineral disease secondary to CKD and cardiovascular pathologies. On the other hand, visceral adiposity has been shown as a risk factor in the general population and in patients with CKD. Specifically, the fat deposited in regions such as the epicardium generates a complex autocrine and paracrine hormonal mechanism that has been associated with cardiovascular complications. Although it has not been widely evaluated, the adipose tissue surrounding the kidneys (perirenal fat [PRF]) could provide additional information of interest in the CKD population. The aim of the study is to assess the relationship between cardiovascular disease, PRF, and the effect of therapeutic interventions for bone and mineral metabolism in patients with CKD. Method This prospective observational and cross-sectional study was designed to evaluate the usage of vitamin D analogs in patients with CKD, focusing on cardiovascular history and PRF accumulation. All the patients were evaluated at the outpatient clinic in Consuelo Hospital in Valencia Spain (January-November 2022). Eighty-three patients with different grades of CKD (G1A1 to G5A3 not on dialysis) were included and follow-up for 24 months. All the patient's data from electronic medical and analytical records were entered into a protocol sheet. The patients that meet the inclusion criteria (eGFR ≤90 or>15 ml/min/1.73 m2; age ≥18 years at the time of signing informed consent, and a life expectancy higher than 1 year) were eligible to participate in the study. As exclusion criteria, patients with an active inflammatory process such as infection, active cancer, or other inflammatory states were excluded beyond those mentioned in inclusion. Patients with an AKI, ADPKD, or CKD requiring RRT were also excluded. Patients were discriminated according to their history of cardiovascular disease (coronary artery disease, stroke, and peripheral vascular disease) and the use of Vitamin D analogs (Cholecalciferol, Calcitriol, and Paricalcitol). The thickness of the PRF was measured in centimeters (cm) through a B-mode ultrasound with a 3.5-MHz convex transductor (Alpinion®; Alpinion Medical Systems, Korea). Patients underwent a bilateral renal ultrasound, and the kidneys were measured anteroposteriorly, transversally, and longitudinally. PRF was measured in the distal third between the cortex and the hepatic border and/or spleen. Results The mean age of the patients was 58.3 ± 16 years. Patients with a cardiovascular disease history showed significantly higher levels of urea (62.0 vs 45.2 mg/dl, p < 0.05), uric acid (5.5 vs 4.3 mg/dl; p < 0.03), intact parathyroid hormone (iPTH) (186.2 vs 65.2 pcg/dl; p0.05) and decreased eGFR (53.55 vs 89.00 ml/min/1.73 mts2). The mean PRF thickness (0.99 vs 0.80 cm; SD ± 0.30; p0.05) was also observed to be elevated with respect to the group who had no previous cardiovascular events (Fig. 1). Moreover, this group showers higher levels (1.2 vs 7.1; p < 0.005) of CRP. Those patients on oral treatment with Paricalcitol (1 mcg/day) had lesser PRF accumulation than those treated with Cholecalciferol (1000 IU/day) or Calcitriol (0.5 mcg/day) (p < 0.05) (Fig. 2). It was not adjusted for confounding factors such as weight, height, or BMI. Conclusion These results show a close relationship between the presence of cardiovascular disease history and a higher accumulation of PRF. The mechanisms by which paricalcitol could influence the decrease in PRF are so far unknown, however, some studies have shown an association between PTH elevation and obesity. Finally, achieving a decrease in the latter could reduce visceral adipose tissue, thus reducing the cardiovascular risk in CKD-affected patients.

Continuous Glucose Monitoring in Older Adults: What We Know and What We Have Yet to Learn.

To assess the growing use of continuous glucose monitoring (CGM) systems by older adults and explore additional areas integration that could benefit adults with frailty. The use of CGM devices has expanded rapidly in the last decade. This has been supported by substantial data showing significant benefit in glycemic metrics: hemoglobin A1c improvements, less hypoglycemia, and improved quality of life. However, sub-populations, such as older persons, exist where available data are limited. Furthermore, frail older adults represent a heterogeneous population with their own unique challenges to the management of diabetes. This group has some of the poorest outcomes related to the sequela of diabetes. For example, hypoglycemia resulting in significant morbidity and mortality is more frequent in older person with diabetes than in younger persons with diabetes. We present a concise literature review on CGM use in the older adult as well as expand upon glycemic and nonglycemic benefits of CGM for patients, caregivers, and providers. Retrospective analysis of inpatient glycemic data of 16,935 older adults with Type 2 diabetes mellitus at Atrium Health Wake Forest Baptist indicated those with fraility managed with insulin or sulfonylurea had the highest rates of delirium (4.8%), hypoglycemia (3.5%), cardiovascular complications (20.2%) and ED visits/hospitalizatoins (49%). In addition, we address special consideration of specific situations including inpatient, palliative and long term care settings. This review article summarizes the available data for CGM use in older adults, discusses the benefits and obstacles with CGM use in this population, and identifies areas of future research needed for improved delivery of care to older persons with diabetes.

Clinical characteristics of new-onset diabetes after liver transplantation and outcomes.

We aimed to identify the characteristics of new-onset diabetes after liver transplantation (LT) (NODAT) and investigate its impacts on post-transplant outcomes. Adult LT patients between 2014 and 2020 who used tacrolimus as initial immunosuppression and survived 3 months at least were evaluated. Patients who developed NODAT within 3 months after LT were classified as NODAT group. Also, patients were further classified as history of diabetes before LT (PHDBT) and non-diabetes (ND) groups. Patient characteristics, post-LT outcomes, and cardiovascular and/or pulmonary complications were compared. A total of 83, 225, and 263 patients were classified into NODAT, PHDBT, and ND groups. The proportion of cholestatic liver disease and rejection within 90 days were higher in NODAT group. Mean serum tacrolimus concentration trough level in the first week after LT was 7.12, 6.12, and 6.12 ng/mL (p < 0.001). Duration of corticosteroids was significantly longer in NODAT compared to PHDBD or ND (416, 289, and 228 days, p < 0.001). Three-year graft and patient survival were significantly worse in NODAT than ND (80.5% vs. 95.0%, p < 0.001: 82.0% vs. 95.4%, p < 0.001) but similar to PHDBT. Adjusted risks of 3-year graft loss and patient death using Cox regression analysis were significantly higher in NODAT compared to ND (adjusted hazard ratio [aHR] 3.41, p = 0.004; aHR 3.61, p = 0.004). Incidence rates of cardiovascular or pulmonary complications after LT in NODAT were significantly higher than ND but similar to PHDBT. Higher initial tacrolimus concentration and early rejection might be risk factors for NODAT. NODAT was associated with worse post-transplant outcomes.

A Retrospective Clinical Study on Cardiovascular Complications from Colorectal Cancer.

To investigate the incidence and risk factors of cardiovascular complications amongst patients with colorectal cancer (CRC). A retrospective cohort study was conducted on 2085 patients diagnosed with CRC in two tertiary hospitals in China between 2015 and 2020. The patients' medical records were reviewed to identify cardiovascular complications, including myocardial infarction, heart failure, stroke, hypertension, coronary heart disease, heart failure, and arrhythmia. The incidence rate of cardiovascular complications was calculated, and Cox proportional hazards regression analysis was used to identify risk factors. Of the 2085 CRC patients, 329 (15.8%) experienced cardiovascular complications during the follow-up period, with an incidence rate of 17.4 cases per 1000 person-years. The risk was significantly higher in patients who were older than 60 years (adjusted hazard ratio [HR] 2.04, 95% confidence interval [CI] 1.22-3.41), had a higher level of low-density lipoprotein cholesterol (LDL-C) (adjusted HR 2.32, 95% CI 1.31-4.10), had higher levels of serum C-reactive protein (CRP) (adjusted HR 1.57, 95% CI 1.21-2.04), or who underwent chemotherapy or radiotherapy. CRC patients with cardiovascular complications had significantly higher levels of oxidative stress markers, including malondialdehyde (MDA) (5.8 ± 1.2 μmol/L vs. 3.4 ± 0.9 μmol/L, p < 0.001), lower levels of superoxide dismutase (SOD) (85.2 ± 15.6 U/mg protein vs. 112.5 ± 21.3 U/mg protein, p < 0.001), and lower levels of glutathione peroxidase (GPx) (15.6 ± 3.2 U/mg protein vs. 20.4 ± 4.1 U/mg protein, p < 0.001) compared to those without complications. A progressive increase was observed in the proportion of CRC patients with cardiovascular complications over time, rising from 10% in the first year to 38% by the tenth year of follow-up. Cardiovascular complications pose a high risk in CRC patients, particularly amongst older patients and those with higher levels of LDL-C or CRP. Regular monitoring of cardiovascular function should be considered in the management of patients with CRC.

Cumulative incidence and mortality rate of cardiovascular complications due to laboratory-confirmed influenza virus infection: A systematic review and meta-analysis.

Influenza infection is associated with cardiovascular complications that range significantly in presentation and severity. The cumulative incidence of cardiovascular complications due to laboratory-confirmed influenza, however, is not reported in the literature. We conducted a systematic review and random-effects meta-analysis to evaluate the cumulative incidence and mortality rate of influenza virus-related cardiovascular complications in hospitalized patients. We searched the PubMed and EMBASE databases for studies reporting acute myocardial infarction (AMI), heart failure (HF), arrhythmia of any kind, stroke or transient ischemic attack (TIA), and myocarditis in hospitalized patients with laboratory-confirmed influenza virus infection. Prospective studies, retrospective cohort studies, and randomized controlled trials (RCTs) were included in the analysis. We followed the PRISMA checklist and used 95% confidence intervals (CIs) to report meta-analysis outcomes. This study was registered on PROSPERO (CRD42023427849). After retrieving 2803 studies, we identified 19 studies (18 observational and 1 RCT) with relevant data, and we included 6936 patients in our analysis, of whom 690 (9.9%) developed a cardiovascular outcome of interest. The cumulative incidence of HF was 17.47% (95% CI: 5.06%-34.54%), arrhythmia of any kind 6.12% (95% CI: 0.00%-21.92%), myocarditis 2.56% (95% CI: 0.66%-5.38%), AMI 2.19% (95% CI: 1.03%-3.72%), and stroke or TIA 1.14% (95% CI: 0.00%-4.05%). The in-hospital mortality rate from cardiovascular events was 1.38% (95% CI: 0.00%-4.80%). Cardiovascular complications occur in patients with influenza virus infection, with the cumulative incidence of specific cardiac manifestations varying considerably (1.51%-17.47%). Preventive strategies and close clinical monitoring after infection remain a priority.

Prevalence of chronic kidney disease in the Netherlands and its cardiovascular and renal complications

BackgroundKnowledge on prevalence, comorbidities and consequences of chronic kidney disease (CKD) is mandatory to estimate the potential of cardiovascular risk management on a population level. We studied the prevalence of CKD with or without type 2 diabetes mellitus (T2D) and/or heart failure and its cardiorenal complications in The Netherlands.MethodsA descriptive cross-sectional and longitudinal cohort study was performed, using data from the Dutch PHARMO Data Network. Prevalence of CKD at a single time point was determined by a recorded diagnosis or by ≥ 2 estimated glomerular filtration rate (eGFR) measurements and urine albumin/creatinine ratio (UACR) that define CKD. A representative group of adults with CKD was included in a longitudinal analysis to study cardiorenal complications. Those were followed until first complication, end of study or death, whichever occurred first.ResultsThe prevalence of CKD was 8.9% in a representative population of 2,187,962 adult Dutch individuals. The average age of persons with CKD was 72 years, 57% were female, 19.9% had T2D, 7.7% heart failure, and 3.0% both T2D and heart failure. In the longitudinal analysis, cerebrovascular events (11/1,000 person-years), hospitalizations for heart failure (10/1,000 person-years), myocardial infarction (5.5/1,000 person-years), and hospitalization for CKD (6.2/1,000 person-years) were the most common first cardiorenal complications. People with CKD with T2D and/or heart failure generally had higher rates of cardiovascular or renal complications or mortality than people with CKD without these comorbidities.ConclusionThe prevalence of CKD in The Netherlands is 8.9%. People with T2D or heart failure, or both, in addition to CKD, had numerically higher mortality and cardiorenal complication rates than people without these comorbidities. Optimizing up-to-date cardiovascular risk management in these high-risk individuals may provide health benefits.

Combined therapy with SGLT2i and GLP-1ra improves cardiovascular prognosis in a population with diabetes and overweigh or obesity. A real-world clinical practice study

Abstract Background Prior clinical trials found diabetic patients treated with SGLT2i and/or GLP1ra had lower rates of cardiovascular complications. Purpose This study (CardioCHUS-T2D) sought to determine the association between initiation of SGLT2i, GLP1ra or both, and major cardiovascular complications or death in high risk diabetic patients. Materials and methods The CardioCHUS-T2D study was an observational study in which adults with type 2 diabetes, older than 65 years old and overweight or obesity were identified in a Galician health area. Patients prescribed an SGLT2i, GLP1ra or both over the last 5 years were matched base on antidiabetic treatment, duration of treatment, sex, age, diabetes duration, arterial hypertension, hyperlipidemia, CAD, HF, atrial fibrillation, CVA and peripheral artery disease (PAD) and were included on a regression Cox for determining the main variables associated with outcomes. After score matching, we selected 5132 patients who were taking SGLT2i, GLP-1ra or both. The data records were obtained from shared electronic patient dossier (EPD). Patients were classified in 3 groups according antidiabetic drugs, SGLT2i or/and GLP-1ra. During follow-up, after treatment intake, the main outcomes were recorded (hospitalization for coronary artery disease (CAD), heart failure (HF) or cerebrovascular accident (CVA) events, overall and cardiovascular death. Results The main clinical characteristics of patients regarding antidiabetic treatment are represented on table 1. No clinical relevant differences were observed between the group of patients treated with any of the monotherapies (SGLT2i or GLP-1ra) and the patients treated with the combined therapy. During the period of observation, the group of patients receiving the combined therapy (SGLT2 + GLP-1ra) were associated with a significant reduction in the risk of suffering heart failure (HF) events (composite of HF hospitalization and HF-related death): HR: 0,651 (95%CI: 0,457-0,927; p=0,017), and all-cause mortality (HR: 0,602 (95%CI:0,443-0,817; p=0,001) (Figure 1) without significative differences in cerebrovascular events. Conclusions In a real-world practice observational study (CardioCHUS-T2D) combined therapy with SGLT2i + GLP1ra in patients with T2D older than 65 years with overweight or obesity was associated with a significative reduction in major cardiovascular complications.Clinical characteristics of patientsKaplan-Meier curves

Abstract 14541: Pericardiocentesis is Associated With Higher Mortality in Patients With Pulmonary Hypertension

Background: Pericardiocentesis in patients with Pulmonary Hypertension (PH) and pericardial effusions has unclear benefits, as it has been associated with acute hemodynamic collapse and increased mortality. Data on in-hospital outcomes in this population is limited. Aims. Describe pericardiocentesis-related patient characteristics and in-hospital outcomes in patients with PH versus without. Methods: The National Inpatient Sample database was used to identify adult patients undergoing pericardiocentesis during hospitalizations between 2016 and 2020. Data were stratified between patients with and without PH. A multivariate regression model was used to estimate the association of PH with pericardiocentesis in-hospital outcomes, adjusting for statistically significant comorbidities. Results: A total of 95,665 hospitalizations with a procedure diagnosis of pericardiocentesis were included, of which 7,770 had PH. Patients with PH tended to be older (67 ± 15.7) and female (56%), had significantly higher rates of hypertension (79% vs 66%, P&lt;0.01), diabetes (26% vs 17%, P&lt;0.01), chronic lung disease (32% vs 23%, P&lt;0.01), chronic liver disease ( 15% vs 12%, P&lt;0.01), CKD ( 44% vs 25%, P&lt;0.01), and chronic heart failure (19% vs 10%, P&lt;0.01). Pericardiocentesis in PH was associated with higher in-hospital all-cause mortality, post-procedure shock, cardiogenic shock, cardiac arrest, and mechanical circulatory support compared to patients without PH. Those presenting with cardiac tamponade had higher odds of mortality, post-procedural shock, and mechanical circulatory support (Figure 1) compared to patients without PH. All P values were &lt; 0.001. Conclusion: PH was associated with higher mortality and a higher rate of cardiovascular complications in patients undergoing pericardiocentesis. Those presenting with tamponade had particularly worse outcomes. Further research on the outcomes of pericardiocentesis in these patients is needed.

A Comprehensive Echocardiographic Portrait of Adult Sickle Cell Disease Patients in the Modern Era

Background Cardiovascular complications, especially pulmonary hypertension, are a known cause of mortality in patients with sickle cell disease (SCD). With advances in medicine and the introduction of various disease-modifying medications, the incidence and prevalence of cardiovascular complications are poorly documented. Aim To determine rates of cardiovascular complications in patients with SCD in the modern era of disease-modifying medications in a single center. Method We performed a retrospective observational single-center study of patients with SCD: all genotyped and ≥16 years old who had a recent echocardiogram performed during the study period of 2019-2023. Demographics, echocardiogram results, and laboratory findings were collected and analyzed. Descriptive statistics are presented in percentages, medians, and interquartile ranges. An unpaired Student's t-test and Fisher's exact test were used to determine, where appropriate, the level of significant differences among continuous and categorical variables, respectively, with p value &amp;lt;0.05 considered statistically significant. Data was analyzed using GraphPad Prism version 9.0.2. Results As of June 2023, 80 patients (38 male and 42 female, median age 30 years) had undergone a routine transthoracic echocardiogram. Sixty-five patients had the HbSS genotype, 8 HbSC, and 7 HbSB null. Sixty-one patients had received at least one treatment, and 19 (24%) were on concurrent therapy. Hydroxyurea was the common SCD-modifying therapy that the patients received (51 patients), followed by L-glutamine and voxelotor (11 each) and crizanlizumab (9 patients). In total, 56 (70%) patients had at least one cardiac abnormality. The most common cardiac abnormality was left atrial dilatation (41%), followed by left ventricular hypertrophy (33%), right atrial dilation (24%), and left ventricular dilatation (23%). Pulmonary hypertension was present in 30 (38%) patients with tricuspid regurgitation velocity (TRV) ≥2.5 msec (Table 1). The cohort of patients with pulmonary hypertension tended to be older (median age 31 years, p=0.0357), have a higher creatinine level (median 0.8, p=0.0414), and have coexisting echocardiographic abnormalities such as left atrial dilatation (70% vs. 24%, p&amp;lt;0.0001) or right atrial dilatation (40% vs. 14%, p=0.0136) than SCD patients without pulmonary hypertension (Table 2). Conclusion We present a comprehensive echocardiographic assessment of patients with SCD. Despite advances in the treatment of SCD, there remains a high prevalence of cardiac involvement in SCD patients. We found out that 70% of the patients we reviewed had at least one cardiac abnormality on echocardiography. Left atrial dilatation and left ventricular hypertrophy were the most common cardiac abnormalities noted. Pulmonary hypertension was observed in 37.5% of patients with co-existing right and left atrial enlargement. Larger studies are needed to corroborate these findings.

Decades of Improvement in Cardiovascular Morbidity and Mortality in Leukemia Patients Reversed in 2020: Covid? Novel Agents? Neither?

Introduction: The incidence of many types of leukemia increases with age. Intensive induction chemotherapy containing cytarabine and an anthracycline has been part of the upfront and salvage treatment of AML for decades. Regimens for the treatment of ALL are also often anthracycline-based. Anthracyclines are associated with a significant risk of cardiotoxicity including anthracycline-related left ventricular dysfunction. Comprehensive baseline evaluation of cardiac function and risk may lead to better risk stratification and selection of patients who are best suited to anthracycline-based therapy. With the advent of more effective, yet less chemo-intense regimens for the management of older or unfit adults with leukemia, for example hypomethylator and venetoclax-based combinations, which gained widespread use with their accelerated approval in November 2018, one would hypothesize decreased rates of cardiovascular complications associated with the treatment of adult leukemia. To further investigate this hypothesis, we performed a nationwide analysis for adults age 25 and older with leukemia of all types and their associated cardiovascular disease related mortality. Methods: We utilized the Wide-ranging Online Data for Epidemiologic Research from the CDC. Patients were identified using ICD codes: C91 (Lymphoid leukaemia, C92 (Myeloid leukaemia), C93 (Monocytic leukaemia), C94 (Other leukaemias of specified cell type), and C95 (Leukaemia of unspecified cell type) with an underlying cause of death I00-I99 (Diseases of the circulatory system). Data was reviewed between 1999 to 2020 and included patients who were aged ≥25. We analyzed the age adjusted mortality rate (AAMR) per 100,000 people and stratified the data by sex, race/ethnicity, and geographical location within the USA by census region. Results: There were a total of 19,368 cardiovascular related deaths in leukemia patients between 1999 and 2020. There has been a decreasing trend in overall mortality associated with cardiovascular diseases from 1999 to 2019, falling from 4.6 to 3.9 deaths per 100,000 people, with an annual percent change of -2.89% (Figure 1). Both sexes mirrored this trend, with female mortality rates improving from 3.4 to 2.7 (APC -3.26%) and male rates from 6.5 to 5.6 (APC -3.07%) between 1999 and 2019. In 2020, it was observed that leukemia patients had an increased cardiovascular related mortality: 4.5 AAMR overall, 3.0 AAMR in females, and 6.5 AAMR in males . There was not a statistically significant difference in mortality changes by race (Table 1). Conclusion: Our study reveals a decrease in mortality rates from cardiovascular disease in leukemia patients from 1999 to 2018 followed by a relatively sharp increase noted in 2020. The steady improvements noted from the early 2000s to the 2010s may be attributable to awareness of known toxicities that led to enhanced screening and active monitoring for cardiovascular complications. Electrocardiograms, echocardiograms, and cardiotoxic markers including troponins and natriuretic peptides have served as diagnostic and risk-stratification tools. In 2020 leukemia patients exhibited a sudden increase in mortality across all sub-groups. One may postulate that this is related to COVID-19-related complications/delays in treatment, however, another possible explanation may be incompletely recognized toxicities of novel therapeutics. Interestingly, preclinical data have demonstrated that venetoclax treatment resulted in cardiac damage as evidenced by major changes in histopathology and markedly elevated cardiac enzymes and hypertrophic genes markers. Moreover, a drastic increase in oxidative stress, as well as inflammatory and apoptotic markers, with a remarkable decline in the levels of Bcl-2 has been observed (AlAsmari et al Int J Mol Sci 2022). Clearly, continued monitoring and further exploration is needed to identify the reason or reasons for the noted 2020 phenomenon. Continued data collection in the post-Covid vaccine era is likely to help to further elucidate the reasons for the unexpected uptick in cardiovascular-related morbidity and mortality in our leukemia patients.

Pericardiocentesis Outcomes in Patients With Pulmonary Hypertension: A Nationwide Analysis from the United States

Pericardiocentesis (PC) in patients with pulmonary hypertension (PH) and pericardial effusions has unclear benefits because it has been associated with acute hemodynamic collapse and increased mortality. Data on in-hospital outcomes in this population are limited. The National Inpatient Sample database was used to identify adult patients who underwent PC during hospitalizations between 2016 and 2020. Data were stratified by the presence or absence of PH. A multivariate regression model and case-control matching was used to estimate the association of PH with PC in-hospital outcomes. A total of 95,665 adults with a procedure diagnosis of PC were included, of whom 7,770 had PH. Patients with PH tended to be older (aged 67 ± 15.7 years) and female (56%) and less frequently presented with tamponade (44.9% vs 52.4%). Patients with PH had significantly higher rates of chronic kidney disease, coronary artery disease, heart failure, and chronic lung disease, among other co-morbidities. In the multivariate analysis, PC in PH was associated with higher all-cause mortality (adjusted odds ratio [aOR] 1.40, confidence interval [CI] 1.30 to 1.51) and higher rates of postprocedure shock (aOR 1.53, CI 1.30 to 1.81) than patients without PH. Mortality was higher in those with pulmonary arterial hypertension than other nonpulmonary arterial hypertension PH groups (aOR 2.35, 95% CI 1.46 to 3.80, p <0.001). The rates of cardiogenic shock (aOR 1.49, 95% CI 1.38 to 1.61), acute respiratory failure (aOR 1.56, 95% CI 1.48 to 1.64), and mechanical circulatory support use (aOR 1.86, 95% CI 1.63 to 2.12) were also higher in patients with PH. There was no significant volume-outcome relation between hospitals with a high per-annum pericardiocentesis volume compared with low-volume hospitals in these patients. In conclusion, PC is associated with increased in-hospital mortality and higher rates of cardiovascular complications in patients with PH, regardless of the World Health Organization PH group.

EVALUATION OF THYROID PROFILE AND ITS PROGNOSTIC VALUE IN PATIENTS OF ACUTE CORONARY SYNDROME

Objective: The objective of the study is to study the association of thyroid dysfunction with acute coronary syndrome (ACS), its complications and duration of hospital stay. Methods: This prospective comparative study was done on 100 patients divided equally into ACS patients with control (normal thyroid function) and ACS patients with thyroid dysfunction admitted in a tertiary care center, Udaipur, Rajasthan with ACS during the period of February 2021–July 2022. We studied the prevalence, prognostic factor of thyroid hormone in these patients. Results: The mean ejection fraction of the control group was 51.16±11.72%, of hypothyroid group was 49.00±13.55% and of hyperthyroid group was 51.12±13.78%. 29 cases of cardiac failures, 38 cases of arrhythmias, and 32 cases of major adverse cardiac events were observed. 56% of patients required thrombolysis, out of which 67.86% were from the subclinical hypothyroid group. The mean hospital stay in control group was 4.53±1.55, in hypothyroid group was 5.27±1.84 and in hyperthyroid group was 7.00±1.92.18% mortality. Conclusion: Patients with acute myocardial infarction, initially develop alteration in thyroid hormone levels, which is possibly a compensatory mechanism to reduce the metabolic demand of the heart, by reducing myocardium contraction and cardiac output but may cause cardiac failure and higher rates of cardiovascular complications like arrhythmias and death in some of the patients. Thyroid dysfunctions in patients with ACS may also need a longer duration of intensive care and close monitoring during follow-up.

Outcomes of emergency colorectal surgery in elderly population.

To assess the outcomes of emergency colorectal surgeries in elderly patients over the age of 65 years. This is a retrospective chart review study. We studied 99 patients over the age of 65 years and 142 patients younger than 65 years who underwent emergency colorectal surgery at our institute. In this study, patient demographics, operative results, length of hospital stay, and survival were analyzed. Emergency colorectal surgery was performed on a total of 145 men and 96 women. Patients over the age of 65 years were found to have a significantly greater proportion of pulmonary, cardiac, and endocrine comorbidities (27.3%, 84.8%, and 65.7%, respectively). The mean length of hospital stay was 26.0±32.1 days in the group of elderly patients and 17.8±22.0 days in the group of patients under the age of 65. The length of postoperative hospital stay was significantly greater in the group of elderly patients with a p-value (0.00). The length of hospital stay in the intensive care unit was 8.86±17.1 days, which was longer in the group of elderly patients, while it was 3.65±11.4 days for the group of younger patients. However, after logistic regression, the difference in the length of post-operative hospital and intensive care unit stays between elderly and non-elderly patients was not statistically significant in elderly patients. Our study suggests that the elderly population are associated with longer hospital stay and higher rates of postoperative pulmonary and cardiovascular complications compared to those under the age of 65. However, after logistic regression, age by itself was not found to be an independent risk factor for worse outcome indicating that patient comorbidities as a whole increase the risk of worse outcomes. Therefore, the care of elderly patients undergoing emergency colorectal surgery should be individualized based on several factors rather than age alone.

Effects of CRT on atrial and ventricular arrhythmias in patients with HF

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Cardiac resynchronization therapy (CRT) is an accepted treatment for patients with heart failure (HF). Cardiac arrhythmias present a significant and complex issue in this patient group. Evidence exploring the influence of CRT on cardiac arrhythmias rate variations is limited. Purpose Our research investigates the effectiveness of CRT in the treatment of existing and newly diagnosed atrial and ventricular arrhythmias, and impact of epicardial lead position on these arrhythmias rate variations, as well as on the CRT response. Methods This single-center, prospective, observational study included 75 consecutive patients admitted for CRT implantation over a 12-month period. All included patients had episodes of atrial and/or ventricular arrhythmias, diagnosed by 12-lead ECG or 24-hour Holter monitoring. Pre-procedural demographic characteristics were collected for all patients, including ECG records, NYHA functional class, echocardiographic assessment of left ventricular ejection function and questionnaire for quality-of-life. During device follow up atrial and ventricular arrhythmias appearance was monitored. Additional assessment of echocardiographic parameters, NYHA - functional class, quality of life and rate of major cardiovascular complications and rehospitalizations was performed. Results The mean age of the patients was 62.4 ± 10.3 years, with 74.6% male and 25.3% females. 72% had a non-ischemic HF etiology. Pre-procedural paroxysmal AF was present in 34.7%, persistent AF in 36%, PVCs in 32%, NSVT 16%, and VT in 18,7% patients. 55% of the included patients were responders to CRT. Our results showed decrease in rate of all ventricular arrhythmias, with significant reduction in the percentage of VT (p=0.003), regardless of CRT response. Significant reduction of PVCs and NSVT rate (p=0.012 &amp; p=0.024) was found in the responder group of patients. Regarding AF, our results showed a decrease in the number of AF events in both patient groups, however this was most visible in the responder patients with paroxysmal AF (p=0.057). In CRT responders, left ventricular pacing lead was most commonly located in a lateral branch vein of the CS with middle and mid/lateral position. In terms of quality of life and general condition of the patients, we noticed a significant improvement in the NYHA - functional class (p &amp;lt;0.001), as well as in both parts of the quality-of-life assessment questionnaire (p=0.0135, p&amp;lt;0.001). Conclusion CRT is an effective treatment for atrial and ventricular arrhythmias in HF patients, especially in responders to this therapy. LV epicardial lead position proved to be very important influence in the process of LV reverse remodeling, which is in direct correlation of the CRT responders and its effectiveness in reducing the rate of cardiac arrhythmias.

Major cardiovascular events and associated factors among routine hemodialysis patients with end-stage renal disease at tertiary care hospital in Somalia.

Cardiovascular complications are the most significant cause of death in patients undergoing routine hemodialysi (HD) with end-stage renal disease (ESRD). The main objective of this study is to determine the significant cardiac events and risk factors in patients undergoing routine hemodialysis in Somalia. We carried out a cross-sectional retrospective study in a single dialysis center in Somalia. Two hundred out of 224 were included. All of them had ESRD and were on hemodialysis during the study period between May and October 2021. The records of all patients were reviewed, and the following parameters were analyzed socio-demographic factors, risk factors for cardiovascular disease, and the presence of cardiovascular diseases. The mean age was 54 ± 17.5 years (range 18-88 years), and 106 (53%) patients were males. The prevalence of a cardiovascular disease among hemodialysis patients was 29.5%. Moreover, the distribution of cardiovascular diseases was different; heart failure was the most common, about 27.1%, followed by coronary artery disease (17%), pericarditis and pericardial-effusion (13.6%), dysrhythmia (10.2%), cerebrovascular-accident (8.5%), and peripheral vascular disease (3.4%). About 176 (88%) participants had at least one modifiable cardiovascular risk factor. The most common modifiable cardiovascular risk factor was hypertension (n = 45, 25.1%), followed by anemia (n = 28, 15.6%) and diabetes (n = 26, 14.5%). Younger (18-30) participants were six times less likely to have cardiovascular events among hemodialysis than older age 0.4 (0.11-1.12). Low prevalence rate of cardiovascular complications was confirmed in ESRD patients receiving hemodialysis in the main HD center in Somalia. Diabetes, anemia, and hypertension were the highest significant risk factors for CVD in HD patients with ESRD in Somalia.

Improving Detection Rates for Primary Aldosteronism.

Primary aldosteronism (PA), once considered a rare disease, is being increasingly recognized as an important cause of hypertension. It is associated with higher rates of cardiovascular complications compared to blood pressure-matched essential hypertension. Targeted treatments are available which can mitigate the excess cardiovascular risks and, in some cases, cure hypertension. Making a timely diagnosis of PA is, therefore, highly beneficial for patients. Furthermore, numerous studies from different parts of the world have found PA to be a relatively common disease that can affect patients in any stage of hypertension, regardless of their age or potassium levels. Despite this well-established data, the current rate of PA detection is appallingly low, much below its actual prevalence. This review explores the challenges that clinicians often face in diagnosing PA and offers strategies that may improve the detection of this potentially curable form of hypertension.

PO-04-156 INSIGHTS REGARDING OUTCOMES FOR COVID-19 HOSPITALIZATIONS WITH ADULT CONGENITAL HEART DISEASE (ACHD)

As of December 2022, SARS-CoV-2 coronavirus resulted in over 6 million deaths worldwide.[1] It was realized early into the pandemic, that COVID-19 significantly impacts the Cardiovascular system. [2] Patients with pre-existing cardiovascular comorbidities were particularly at higher risk of adverse outcomes during their hospitalizations. [3] Similarly, it can be safe to assume patients with adult congenital heart disease (ACHD) should considered a high-risk population for the development of severe COVID infection with increased rates of significant cardiovascular complications. Based on this reasoning and the paucity of data available on this topic using a large database, we sought to investigate the outcomes of patients with ACHD who were admitted to the hospital with COVID-19. The National Inpatient Sample database for 2020 was queried to identify adult hospitalizations with a primary diagnosis of COVID-19 and a secondary diagnosis of ACHD using International Classification of Diseases – 10 Clinical Modification (ICD-10-CM) codes. The primary outcome studied was inpatient mortality, while secondary outcomes included inpatient complications, mean length of stay (LOS), and total hospital charge (THC). Multivariate logistic and linear regression analyses were used to adjust for possible confounders and analyze the variables. Out of 1,050,045 COVID-19 hospitalizations registered, 2,425 (0.23%) had ACHD as a secondary diagnosis. Encounters with ACHD who were hospitalized with COVID-19 had significantly higher adjusted odds of inpatient mortality (Adjusted Odds Ratio [aOR]: 1.4, [95% CI: 1.05-1.88], p=0.022), Longer LOS (Mean 2.4 days, [95% CI: 1.35-3.40], p <0.001), and higher Total Hospital Charges (Mean $53,000, [95% CI: 20811-85190], p <0.001). A Forrest plot (Figure 1) demonstrates a graphical representation of the multivariate analysis of the significant in-hospital complications when adjusted for patient demographics, comorbidities, and hospital characteristics. Among COVID-19 hospitalizations, those with a history of congenital heart diseases had significantly worse outcomes in terms of in-hospital mortality, sepsis; the need for endotracheal intubation, mechanical ventilation, and vasopressors; developing acute kidney injury and pulmonary embolism, in addition to the longer length of stay, and higher total hospital charges.

Abstract 374: Sexual Dimorphism And Elabela Expression In Peripheral Artery Disease

Introduction: Elabela is a component of the apelinergic system known to regulate immune responses and has a cardiovascular protection role, including atherosclerosis. Peripheral artery disease (PAD) is the narrowing or blockage of larger arteries in the legs. Patients with PAD suffer from poor perfusion to their lower extremities, in addition to increased rates of cardiovascular complications. The role of sexual dimorphism in the immune system in the PAD is poorly understood. Our previous research suggests that Elabela may hold a gender-dependent protective role that can be used as immunotherapeutic. We hypothesized that in patients with PAD, expression of Elabela will be different between males and females, implicating in sexual dimorphism of the immune response, the disease outcome, and treatment. Methods: Blood samples were collected from PAD patients (n=8) and risk factor closely matched controls (n=8). PBMCs were isolated by gradient centrifugation. By flow cytometry, gating strategy on Elabela, and Elabela expressing leukocytes, using FlowJow software for analysis. Results: The results showed that there is a sexual difference in the expression of Elabela in both controls and patients with PAD. In general, males showed a high level of Elabela than females. PAD decreases Elabela expression in both males and females. Regarding Elabela expressing leukocytes, in female controls, there was no significant difference in leukocyte expression of Elabela as compared to PAD patients, while male controls demonstrated increased leukocyte expression of Elabela. Conclusions: Our findings suggest a potential role for Elabela in PAD. Importantly, these results also indicate a difference in Elabela expression based on sex dimorphism. Such differences could potentially be used as a biomarker in the diagnosis and prognosis of PAD along with therapeutic values.

Incidence of acute kidney injury after noncardiac surgery in patients receiving intraoperative dexmedetomidine: a retrospective study

BackgroundPostoperative acute kidney injury (AKI) is a common complication and is associated with increased hospital length of stay and 30 day all-cause mortality. Unfortunately, we have neither a defined strategy to prevent AKI nor an effective treatment. In vitro, animal, and human studies have suggested that dexmedetomidine may have a renoprotective effect. We conducted a retrospective cohort study to evaluate if intraoperative dexmedetomidine was associated with a reduced incidence of AKI. MethodsWe collected data from 6625 patients who underwent major non-cardiothoracic cancer surgery. Before and after propensity score matching, we compared the incidence of postoperative AKI in patients who received intraoperative dexmedetomidine and those who did not. AKI was defined according to the Kidney Disease Improving Global Outcomes (creatinine alone values) criteria and calculated for postoperative Days 1, 2, and 3. ResultsTwenty per cent (n=1301) of the patients received dexmedetomidine. The mean [standard deviation] administered dose was 78 [49.4] mcg. Patients treated with dexmedetomidine were matched to those who did not receive the drug. Patients receiving dexmedetomidine had a longer anaesthesia duration than the non-dexmedetomidine group. The incidence of AKI was not significantly different between the groups (dexmedetomidine 8% vs no dexmedetomidine 7%; P=0.333). The 30 day rates of infection, cardiovascular complications, or reoperation attributable to bleeding were higher in patients treated with dexmedetomidine. The 30 day mortality rate was not statistically different between the groups. ConclusionsThe administration of dexmedetomidine during major non-cardiothoracic cancer surgery is not associated with a reduction in AKI within 72 h after surgery.
