A Comprehensive Review on the Electrocardiographic Manifestations of Cardiac Sarcoidosis: Patterns and Prognosis.

PURPOSE OF REVIEW: Cardiac sarcoidosis (CS) refers to cardiac involvement in sarcoidosis and is usually associated with worse outcomes. This comprehensive review aims to elucidate the electrocardiographic (ECG) signs and features associated with CS, as well as examine modern techniques and their importance in CS evaluation. RECENT FINDINGS: The exact pathogenesis of CS is still unclear, but it stems from an abnormal immunological response triggered by environmental factors in individuals with genetic predisposition. CS presents with non-cardiac symptoms; however, conduction system abnormalities are common in patients with CS. The most common electrocardiographic (ECG) signs include atrioventricular blocks and ventricular tachyarrhythmia. Distinct patterns, such as fragmented QRS complexes, T-wave alternans, and bundle branch blocks, are critical indicators of myocardial involvement. The application of advanced ECG techniques such as signal-averaged ECG, Holter monitoring, wavelet-transformed ECG, microvolt T-wave alternans, and artificial intelligence-supported analysis holds promising outcomes for opportune detection and monitoring of CS. Timely utilisation of inexpensive and readily available ECG possesses the potential to allow early detection and intervention for CS. The integration of artificial intelligence models into ECG analysis is a promising approach for improving the ECG diagnostic accuracy and further risk stratification of patients with CS.

Evaluating the role of ivabradine in acute decompensated heart failure: A systematic review and meta-analysis.

BACKGROUND: Acute decompensated heart failure (ADHF) presents a significant global health challenge, with high morbidity, mortality, and healthcare costs. The current therapeutic options for ADHF are limited. Ivabradine, a selective inhibitor of hyperpolarization-activated cyclic nucleotide-gated (HCN) channels, has emerged as a potential therapy for ADHF by reducing the heart rate (HR) without negatively affecting myocardial contractility. However, the evidence regarding the efficacy and safety of ivabradine in patients with ADHF is limited and inconsistent. This meta-analysis aimed to evaluate the efficacy and safety of ivabradine for ADHF based on observational studies. METHODS: A systematic literature search was conducted following PRISMA guidelines to identify relevant observational studies comparing ivabradine with placebo in adult patients with ADHF. Data were pooled using a random-effects model, and heterogeneity was assessed. The risk of bias was evaluated using the Newcastle-Ottawa Scale. RESULTS: Four observational studies comprising a total of 12034 patients. Meta-analysis revealed that ivabradine significantly reduced all-cause mortality (RR: 0.66, 95 % CI: 0.49-0.89, p < 0.01) and resting HR (MD: -12.54, 95 % CI: -21.66-3.42, p < 0.01) compared to placebo. However, no significant differences were observed in cardiovascular mortality, hospital readmission for all causes, changes in LVEF, or changes in LVEDD. Sensitivity and publication bias assessments were conducted for each outcome. CONCLUSION: Ivabradine may be beneficial for reducing mortality and HR in patients with ADHF. However, its impact on other clinical outcomes such as cardiovascular mortality, hospital readmission, and cardiac function remains inconclusive. Further research, particularly well-designed RCTs with larger sample sizes and longer follow-up durations, are warranted.

Air pollution and cardiovascular health in South Asia: A comprehensive review.

Air pollution is a pressing environmental health concern, with a growing impact on developing nations, particularly in South Asia. Extensive research has linked air pollution to various diseases, including cardiovascular diseases (CVDs). In South Asia, air pollution is a critical issue, with a high concentration of the world's most polluted cities and widespread exposure to particulate matter (PM2.5) exceeding World Health Organization (WHO) guidelines. WHO reports that outdoor and indoor air pollution together claim 7 million lives annually. Fine particulate matter (PM2.5) and ground-level ozone are prominent culprits. South Asia, with 60 % of its population exposed to hazardous pollution levels, is home to 37 of the world's 40 most polluted cities. PM2.5 concentrations in South Asia often exceed WHO guidelines by up to 20 times. Air pollution in this region, driven by factors such as crop stubble burning, is a leading cause of CVD. Studies in the region have revealed a significant correlation between PM2.5 levels and CVDs, with fine particles originating from sources like industrial emissions and traffic playing a central role in cardiovascular health deterioration. Exposure to PM2.5 leads to oxidative stress, inflammation, and hypercoagulability, increasing the risk of conditions such as ischemic heart disease and stroke. In South Asia, the burden of CVDs associated with air pollution is substantial, with millions of premature deaths attributed to outdoor and indoor air pollution. To mitigate this crisis, a multifaceted approach is essential, encompassing public awareness, air quality regulation, cleaner energy sources, and measures to reduce crop stubble burning. Additionally, further research is crucial to understanding the complex relationship between air pollution and CVDs in South Asia, as it offers avenues for prevention and control, potentially saving lives and improving public health in the region.

Obesity, Cardiovascular Disease, and the Promising Role of Semaglutide: Insights from the SELECT Trial.

Cardiovascular disease (CVD) is a leading global cause of death, with preventable risk factors like obesity contributing most to it. Obesity's association with CVD originate from factors like inflammation, insulin resistance, and altered lipid profiles. Obesity also raises the risk of atrial fibrillation (AF) and sudden cardiac death. Semaglutide, a GLP-1 receptor agonist, initially used for weight loss and diabetes, emerged as a breakthrough in CVD prevention. The SELECT trial assessed semaglutide's impact on major adverse cardiovascular events (MACE). In this double-blind, placebo-controlled trial, 17,604 adults with CVD and obesity were given a weekly 2.4 mg dose of semaglutide or placebo. The trial observed a significant 20% reduction in MACE risk for those receiving semaglutide, demonstrating its potential in obesity-associated CVD prevention. This shift marks a transformative approach to obesity management and CVD prevention. However, further research is needed to fully comprehend semaglutide's cardiovascular benefits and potential risks.

Hypertension and Lorundrostat: Key Discoveries From the TARGET-HTN Trial.

Hypertension, characterized by persistent high blood pressure levels, is a major global health concern, contributing significantly to the risk of cardiovascular diseases (CVD) and overall mortality. It is classified into primary and secondary hypertension, with its prevalence steadily increasing due to ageing populations and unhealthy lifestyle factors. The World Health Organization (WHO) reports a staggering rise in hypertension cases, affecting one in 3 adults worldwide, doubling from 1990 to 2019. A significant development in the field of hypertension treatment is the Target-HTN trial, which investigated the efficacy of lorundrostat, an aldosterone synthase inhibitor, in reducing systolic blood pressure. This trial involved 2 cohorts. Cohort 1, comprising patients with suppressed plasma renin activity and elevated serum aldosterone levels, showed promising results. Lorundrostat doses of 100 mg and 50 mg administered once daily led to substantial reductions in systolic blood pressure compared to a placebo group. Cohort 2, although considered exploratory, also exhibited a notable reduction in systolic blood pressure with a 100 mg once-daily dose of lorundrostat. In conclusion, the Target-HTN trial has demonstrated that lorundrostat, an aldosterone synthase inhibitor, holds promise as an innovative therapeutic approach for reducing systolic blood pressure, especially in hypertensive patients with suppressed plasma renin activity and elevated serum aldosterone levels. These findings advocate for the initiation of Phase 3 trials to further validate the safety and efficacy of lorundrostat in a larger and more diverse patient population.

Safety and Efficacy of Hypoxia-Inducible Factor-Prolyl Hydroxylase Inhibitors vs. Erythropoietin-Stimulating Agents in Treating Anemia in Renal Patients (With or Without Dialysis): A Meta-Analysis and Systematic Review.

Hypoxia-inducible factor-prolyl hydroxylase domain inhibitors (HIF-PHIs) are a novel group of drugs used to treat renal anemia, but their benefits vary among different trials. Our meta-analysis aims to assess the safety and efficacy of HIF-PHI versus erythropoiesis-stimulating agents (ESA) in managing anemia among patients with chronic kidney disease (CKD), regardless of their dialysis status. PubMed, Embase, and Google Scholar were queried to discover eligible randomized controlled trials (RCTs). To quantify the specific effects of HIF-PHI, we estimated pooled mean differences (MDs) and relative risks (RR) with 95% CIs. Our meta-analysis involved 22,151 CKD patients, with 11,234 receiving HIF-PHI and 10,917 receiving ESA from 19 different RCTs. The HIF-PHI used included roxadustat, daprodustat, and vadadustat. HIF-PHI yielded a slight but significant increase in change in mean hemoglobin (Hb) levels (MD: 0.06, 95% CI (0.00, 0.11); p = 0.03), with the maximum significant increase shown in roxadustat followed by daprodustat as compared to ESA. There was a significant decrease in efficacy outcomes such as change in mean iron (MD: -1.54, 95% CI (-3.01, -0.06); p = 0.04), change in mean hepcidin (MD: -21.04, 95% CI (-28.92, -13.17); p < 0.00001), change in mean ferritin (MD: -16.45, 95% CI (-27.17,-5.73); p = 0.03) with roxadustat showing maximum efficacy followed by daprodustat. As for safety, HIF-PHI showed significantly increased incidence in safety outcomes such as diarrhea (MD: 1.3, 95% CI (1.11, 1.51); p = 0.001), adverse events leading to withdrawal (MD: 2.03, 95% CI (1.5, 2.74), p = 0.00001) among 25 various analyzed outcomes. This meta-analysis indicates that HIF-PHIs present a potentially safer and more effective alternative to ESAs, with increased Hb levels and decreased iron usage in CKD patients without significantly increasing adverse events. Therefore, in these patients, we propose HIF-PHI alongside renal anemia treatment.
