IntroductionThe objective of this study was to analyze the temporal trends and demographic/geographical disparities in acute myocardial infarction (AMI)-related mortality among individuals aged 15 and older across the United Sates (US).Material and methodsWe evaluated death records from 1999 to 2020 that were obtained from the CDC WONDER database. Age-adjusted mortality rates (AAMRs) per 100,000 persons and annual percent changes (APC) were computed, with stratification by year, sex, race/ethnicity, and geographic region.ResultsBetween 1999 and 2020, 3,016,546 AMI-related deaths were reported in the United States. The overall AAMR was 51.9 per 100,000 (95% CI: 51.8–52.0). Over the course of the study, the crude mortality rate (CMR) increased with age. Males exhibited a consistently higher overall annual AAMR (67.4, 95% CI: 67.3, 67.5) than females (39.5, 95% CI: 39.4, 39.6). In comparison to other races, Black (or African American) people had the highest death rates, with an AAMR of 58.9 (95% CI: 58.7, 59.1). The South region mortality rate (AAMR = 57.7; 95% CI: 57.6, 57.8) was higher than that of the Northeast, Midwest, and West. Specifically, Kentucky had the highest death rate (87.7, 95% CI: 87.0, 88.3), followed by Missouri (80.3, 95% CI: 79.8, 80.8) and Mississippi (85.6, 95% CI: 85.0, 86.6).ConclusionsDuring the period from 1999 to 2020, males, Black/African American adults and those living in the South and other nonmetropolitan areas of the country typically had the highest AAMRs.
Hypertrophic cardiomyopathy (HCM) is an autosomal dominant disorder with risk of sudden cardiac death (SCD) in children and adolescents. Mavacamten, also referred to as MYK-461, a myosin inhibitor of cardiac myocytes is studied in symptomatic HCM. The safety and efficacy of this medication is not well studied in pooled meta-analysis. Online database search was performed from inception to September 2023. We selected randomized clinical trials that compared Mavacamten with placebo/guideline medical treatment for HCM. We studied safety outcomes (Serious adverse events (SAEs), treatment emergent adverse events (TEAs) and Atrial fibrillation). Functional status of patients was assessed as New York Heart Association (NYHA) Classification improvement of at least + 1 grade, Kansas City Cardiomyopathy Questionnaire Clinical Summary Score (KCCQ-CSS) change from baseline). Relative risk ratios were used in randomized model using Review Manager Version 5.4 statistical software. A total of 4 RCTs comprising 503 patients were included in meta-analysis. On random effect model, we found that HCM patients that received Mavacamten had significant symptomatic improvement as depicted by improvement in NYHA class by at least + 1 grade (RR = 2.15; P < 0.0001) and KCCQ CSS score improvement (MD = 8.38; P < 0.00001) as compared to placebo arm. There was no statistically significant difference in SAEs (RR = 0.87; P = 0.69) and atrial fibrillation onset (RR = 0.80; P = 0.73) between HCM and placebo arm. The studies had low heterogeneity/publication bias. Mavacamten can improve symptoms in HCM patients, and can be additive to other alternative regimen in HCM patients with no statistical significance of risk of SAE or atrial fibrillation onset as compared to placebo.
Heart failure is a growing global health concern with high mortality and morbidity. Beta-blockers, mineralocorticoid receptor antagonists, and angiotensin-converting-enzyme inhibitors are the treatments of choice for worsening clinical symptoms. In early 2021, the FDA approved a new oral soluble guanylate cyclase stimulator, Vericiguat, for the treatment of chronic heart failure. To evaluate the efficacy and safety of this approved drug, we conducted a systematic review of the available randomized controlled trials (RCTs). A literature search was conducted using PubMed, The Cochrane Library, and Clinicaltrials.gov from inception to June 6, 2022, without any language restriction. The systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. The quality of the included studies was checked using the Cochrane Risk-of-Bias tool. After a thorough literature search, 7 studies met our pre-defined criteria and were therefore included in this review. Our review suggests that vericiguat was better in preventing all causes of death, cardiovascular death, and hospitalizations due to heart failure irrespective of the atrial fibrillation status of the patients and was even beneficial for patients with NT-proBNP levels up to 8000 pg/ml. The safety of the vericiguat, according to our review, is not up to the standards, especially with a higher dosage of vericiguat. Despite all of this, vericiguat can be a breakthrough in the treatment of heart failure as it has great potential to improve the disease severity.
INTRODUCTION:Sydenham's chorea (SC), prevalent in developing countries and occasionally affecting developed ones, poses a clinical challenge due to the lack of systematic guidelines for diagnosis and treatment. Resulting from Group A Beta-Hemolytic Streptococcus infection, SC presents various symptoms. This review aims to collect and evaluate available data on SC management to propose a cohesive treatment plan. METHODS:We searched PubMed, the Cochrane Library, Google Scholar, and ClinicalTrials.gov for literature on SC management from inception until 24th July 2022. Studies were screened by titles and abstracts. Cochrane Collaboration's Risk of Bias tool (RoB-1) assessed Randomized Controlled Trials, while the Risk of Bias In Non-randomized Studies of Interventions (ROBINS-I) tool evaluated nonrandomized studies. RESULTS:The review includes 11 articles assessing 579 patients. Excluding one study with 229 patients, of the remaining 550 patients, 338 (61.5%) were females. Treatments used were dopamine antagonists in 118 patients, antiepileptics in 198, corticosteroids in 134, IVIG in 7, and PE in 8 patients. Dopamine antagonists, particularly haloperidol, were the primary treatment choice, while valproic acid (VPA) was favored among antiepileptics. Prednisolone, a corticosteroid, showed promising results with weight gain as the only side-effect. Our review emphasizes the importance of immunomodulators in SC, contrasting previous literature. CONCLUSION:Despite limitations, dopamine antagonists can serve as first-line agents in SC management, followed by antiepileptics. The role of immunomodulators warrants further investigation for conclusive recommendations.
