Sex Disparity in the In-Hospital Outcomes of Patients with Kidney Disease Admitted for Myocardial Infarction: Insights from a Large National Database.

INTRODUCTION: There is limited evidence as to the effect of sex on the outcomes of patients admitted for ST-elevation myocardial infarction (STEMI) who have a concomitant diagnosis of chronic kidney disease (CKD) and end-stage renal disease (ESRD). We aimed to determine if there are differences in the outcomes between males and females in these patient populations. METHODS: Data were obtained from the National Inpatient Sample database and patients were selected using the International Classification of Diseases, Ninth and Tenth Revision (ICD-9 and -10) codes. Hospitalizations for patients with CKD who had STEMI from 2012 to 2020 were included. The primary outcome of interest was in-hospital mortality. Secondary outcomes evaluated included ischemic stroke, major bleeding complications, pressor requirement, permanent pacemaker implantation, percutaneous coronary intervention, coronary artery bypass grafting, surgery, pericardiocentesis, mechanical circulatory support, and mechanical ventilation. RESULTS: A total of 1,283,255 STEMI patients without CKD, 158,715 STEMI patients with CKD, and 22,690 STEMI patients with ESRD were identified and analyzed. Among patients with STEMI and CKD, females demonstrated higher in-hospital mortality compared to male counterparts (16.7% vs. 12.7%, aOR = 1.13, 95% CI: 1.05-1.21, p < 0.01). While there was no sex difference in the in-hospital mortality among STEMI patients with ESRD, female patients in this group were less likely to receive coronary artery bypass grafting and mechanical circulatory support. CONCLUSION: Increased in-hospital mortality rates were shown for females admitted for STEMI with CKD. Among patients with ESRD who had STEMI, females were less likely to receive coronary artery bypass grafting and mechanical circulatory support. Further research needs to be conducted to better explain this said difference in outcomes.

Evaluating the safety profile of semaglutide: an updated meta-analysis.

BACKGROUND: Semaglutide is increasingly used in the management of type 2 diabetes mellitus and obesity. Ensuring the safety of this medication is crucial for its clinical use. This meta-analysis evaluates the safety profile of semaglutide across patient populations and treatment durations. METHODS: Randomized controlled trials assessing the safety of semaglutide vs. placebo, with specified treatment durations were identified. The primary outcome was occurrence of any cardiovascular adverse events. Secondary outcomes included sudden cardiac death, adverse events leading to death, adverse events, gastrointestinal side effects, occurrence of hypoglycemia, and new-onset neoplasm. RESULTS: A total of 23 studies met the inclusion criteria with a combined sample size of 57,911 participants. The meta-analysis revealed that the adverse event associated with semaglutide is gastrointestinal in nature (nausea and vomiting). No significant differences were observed between semaglutide and comparator groups. CONCLUSION: Semaglutide appears to have a favorable safety profile across diverse patient populations and treatment durations, supporting its continued use in the management of type 2 diabetes mellitus and obesity. It is generally well-tolerated, with a low incidence of adverse events. Clinicians should be aware of these findings and monitor patients accordingly. Further long-term studies are warranted to assess the safety of semaglutide in clinical practice.

The Roles of Non-Pharmacologic and Emerging Pharmacologic Management of Non-alcoholic Fatty Liver Disease and Sarcopenia: A Narrative Review.

Non-alcoholic fatty liver disease (NAFLD) is one of the most prevalent causes of chronic liver disease worldwide which is often seen in patients with metabolic abnormalities such as those with obesity and insulin resistance. On the other hand, sarcopenia is a generalized and progressive skeletal muscle disorder characterized by low muscle strength, low muscle quality, low physical performance, or a combination of the three. Both disease entities share several underlying risk factors and pathophysiologic mechanisms. These include: (1) cardiometabolic overlaps such as insulin resistance, chronic systemic inflammation, decreased vitamin D levels, sex hormone modifications; (2) muscle-related factors such as those mitigated by myostatin signaling, and myokines (i.e., irisin); and (3) liver-dysfunction related factors such as those associated with growth hormone/insulin-like growth factor 1 Axis, hepatokines (i.e., selenoprotein P and leukocyte cell-derived chemotaxin-2), fibroblast growth factors 21 and 19 (FGF21 and FGF19), and hyperammonemia. This narrative review will examine the pathophysiologic overlaps that can explain the links between NAFLD and sarcopenia. Furthermore, this review will explore the emerging roles of nonpharmacologic (e.g., weight reduction, diet, alcohol, and smoking cessation, and physical activity) and pharmacologic management (e.g., roles of ß-hydroxy-ß-methylbutyrate, branched-chain amino acid supplements, and testosterone therapy) to improve care, intervention sustainability, and acceptability for patients with sarcopenia-associated NAFLD.

Glucagon-like peptide-1 receptor agonists modestly reduced blood pressure among patients with and without diabetes mellitus: A meta-analysis and meta-regression.

AIM: The cardiovascular benefits provided by glucagon-like peptide-1 receptor agonists (GLP-1RAs) extend beyond weight reduction and glycaemic control. One possible mechanism may relate to blood pressure (BP) reduction. We aim to quantify the BP-lowering effects of GLP1-RAs. METHODS: A comprehensive database search for placebo-controlled randomized controlled trials on GLP-1RA treatment was conducted until December 2023. Data extraction and quality assessment were carried out, employing a robust statistical analysis using a random effects model to determine outcomes with a mean difference (MD) in mmHg and 95% confidence intervals (CIs). The primary endpoint was the mean difference in systolic BP (SBP) and diastolic BP. Subgroup analyses and meta-regressions were done to account for covariates. RESULTS: Compared with placebo, GLP-1RAs modestly reduced SBP [semaglutide: MD -3.40 (95% CI -4.22 to -2.59, p < .001); liraglutide: MD -2.61 (95% CI -3.48 to -1.74, p < .001); dulaglutide: MD -1.46 (95% CI -2.20 to -0.72, p < .001); and exenatide: MD -3.36 (95% CI -3.63 to -3.10, p < .001)]. This benefit consistently increased with longer treatment durations. Diastolic BP reduction was only significant in the exenatide group [MD -0.94 (95% CI -1.78 to -0.1), p = .03]. Among semaglutide cohorts, mean changes in glycated haemoglobin and mean changes in body mass index were directly associated with SBP reduction. CONCLUSION: Patients on GLP-1RA experienced modest SBP lowering compared with placebo. This observed effect was associated with weight/body mass index reduction and better glycaemic control, which suggests that BP-lowering is an indirect effect of GLP-1RA and unlikely to be responsible for the benefits.

Sex differences in trends and in-hospital outcomes of acute myocardial infarction in patients with familial hypercholesterolemia: insights from a large national database.

BACKGROUND: Sex differences in clinical outcomes following acute myocardial infarction (AMI) are well known. However, data on sex differences among patients with familial hypercholesterolemia (FH) are limited. We aimed to explore sex differences in outcomes of AMI among patients with FH from a national administrative dataset. RESEARCH DESIGN AND METHODS: We utilized the National Inpatient Sample to identify admissions with a primary diagnosis of AMI and a secondary diagnosis of FH. Our primary outcome of interest was in-hospital mortality; secondary outcomes were performance of percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), respiratory complications, use of inotropes, use of mechanical circulatory support (MCS), bleeding complications, transfusion and facility discharge. We adjusted for demographics (model A), comorbidities (model B), and intervention (model C). RESULTS: Between October 2016 and December 2020, 5,714,993 admissions with a primary diagnosis of AMI were identified, of which 3,035 (0.05%) had a secondary diagnosis of FH. In-hospital mortality did not differ between men and women (Model C, adjusted OR = 0.85; 95% CI 0.28-2.60, p = 0.773). There was no sex difference in the secondary outcomes. CONCLUSION: Despite generally being older and having more comorbidities, women with FH fair equally with men with FH in terms of mortality during AMI admission.

Sex differences in trends and outcomes of acute myocardial infarction with mechanical complications in the United States.

BACKGROUND: Mechanical complications (MC) are rare but significant sequelae of acute myocardial infarction (AMI). Current data on sex differences in AMI with MC is limited. METHODS: We queried the National Inpatient Sample database to identify adult patients with the primary diagnosis of AMI and MC. The main outcome of interest was sex difference in-hospital mortality. Secondary outcomes were sex differences in the incidence of acute kidney injury (AKI), major bleeding, use of inotropes, permanent pacemaker implantation (PPMI), performance of percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), surgery (VSD repair and MV surgery), pericardiocentesis, use of mechanical circulatory support (MCS), ischemic stroke, and mechanical ventilation. RESULTS: Among AMI-MC cohort, in-hospital mortality was higher among females compared to males (41.24% vs 28.13%: aOR 1.39. 95% CI 1.079-1.798; p = 0.01). Among those who had VSD, females also had higher in-hospital mortality compared to males (56.7% vs 43.1%: aOR 1.74, 95% CI 1.12-2.69; p = 0.01). Females were less likely to receive CABG compared to males (12.03% vs 20%: aOR 0.49 95% CI 0.345-0.690; p < 0.001). CONCLUSION: Despite the decreasing trend in AMI admission, females had higher risk of MC and associated mortality. Significant sex disparities still exist in AMI treatment.

Efficacy and Safety of Colchicine for the Prevention of Postoperative Atrial Fibrillation Among Patients Undergoing Major Cardiothoracic Surgery: A Meta-analysis and Meta-regression of Randomized Controlled Trials.

ABSTRACT: The role of colchicine for the prevention of postoperative atrial fibrillation (POAF) after cardiothoracic surgery is not well-established. We aimed to evaluate its potential in preventing POAF using data from randomized controlled trials (RCTs). A literature search was performed to identify studies reporting POAF as an outcome after cardiac or thoracic surgery in adult patients randomized to either colchicine or placebo. Primary outcome measured was incidence of POAF. Secondary outcomes included gastrointestinal (GI) adverse effects, sepsis, and length of stay. Subgroup analyses based on treatment durations and type of surgery were also performed, as well as regression analyses to control for covariates. We identified a total of 5377 patients (colchicine = 2,689, placebo = 2688). Although colchicine use was associated with a significantly reduced risk of POAF, risk of GI adverse effects were significantly higher. The rates of infection and length of stay were similar across the groups. Subgroup analyses showed that colchicine was effective for POAF prevention in cardiac surgery, but not in thoracic surgery. Prevention of POAF and incidence of GI adverse effects were similar in short-term and long-term colchicine treatment. Colchicine significantly reduces the incidence of POAF in patients undergoing cardiac surgery, but not in thoracic surgery.

End-Of-Life Care for Patients With End-Stage Heart Failure, Comparisons of International Guidelines.

Heart failure (HF) is a chronic, debilitating condition associated with significant morbidity, mortality, and socioeconomic burden. Patients with end-stage HF (ESHF) who are not a candidate for advanced therapies will continue to progress despite standard medical therapy. Thus, the focus of care shifts from prolonging life to controlling symptoms and improving quality of life through palliative care (PC). Because the condition and prognosis of HF patients evolve and can rapidly deteriorate, it is imperative to begin the discussion on end-of-life (EOL) issues early during HF management. These include the completion of an advance directive, do-not-resuscitate orders, and policies on device therapy and discontinuation as part of advance care planning (ACP). ESHF patients who do not have indications for advanced therapies or those who wish not to have a left ventricular assist device (LVAD) or heart transplant (HT) often experience high symptom burden despite adequate medical management. The proper identification and assessment of symptoms such as pain, dyspnea, nausea, depression, and anxiety are essential to the management of ESHF and may be underdiagnosed and undertreated. Psychological support and spiritual care are also crucial to improving the quality of life during EOL. Caregivers of ESHF patients must also be provided supportive care to prevent compassion fatigue and improve resilience in patient care. In this narrative review, we compare the international guidelines and provide an overview of end-of-life and palliative care for patients with ESHF.

HIV-Associated Nephropathy in 2022.

Background: HIV-associated nephropathy (HIVAN) is a renal parenchymal disease that occurs exclusively in people living with HIV. It is a serious kidney condition that may possibly lead to end-stage kidney disease, particularly in the HIV-1 seropositive patients. Summary: The African-American population has increased susceptibility to this comorbidity due to a strong association found in the APOL1 gene, specifically two missense mutations in the G1 allele and a frameshift deletion in the G2 allele, although a "second-hit" event is postulated to have a role in the development of HIVAN. HIVAN presents with proteinuria, particularly in the nephrotic range, as with other kidney diseases. The diagnosis requires biopsy and typically presents with collapsing subtype focal segmental glomerulosclerosis and microcyst formation in the tubulointerstitial region. Gaps still exist in the definitive treatment of HIVAN - concurrent use of antiretroviral therapy and adjunctive management with like renal-angiotensin-aldosterone system inhibitors, steroids, or renal replacement therapy showed benefits. Key Message: This study reviews the current understanding of HIVAN including its epidemiology, mechanism of disease, related genetic factors, clinical profile, and pathophysiologic effects of management options for patients.

Takayasu's arteritis with giant left ventricular pseudoaneurysm presenting as heart failure.

Takayasu's arteritis (TA) is a vasculitis with a predilection for young women. Left ventricular pseudoaneurysm (PSA) in TA is a rare phenomenon. We report a 36 years old Filipina who presented with heart failure symptoms. Years prior, she had a recurrent fever, headache, myalgia and left arm claudication. On workup, a 2D echo revealed a left ventricular PSA with mural thrombus and moderate mitral regurgitation. Cardiac MRI further characterised the PSA with a sac diameter of 8×7.5×8.4 cm (CC×T×AP). Carotid Duplex Scan revealed total occlusion of the mid to distal right common carotid artery and left subclavian artery. She was started on immunosuppresants and guideline-directed medical therapy (GDMT) for heart failure and subsequently underwent successful endoventricular patch closure and mitral valve repair. This case highlights the importance of actively searching for cardiac complications of TA which although very rare, can dominate the clinical picture and may carry a dismal prognosis if left untreated.
