Mechanisms of exercise-related neurocardiogenic syncope and the relationship between resting and dynamic cardiac testing.
Cardiol Young
January 2025
Department of Pediatrics, University of Cincinnati College of Medicine, Cincinnati, OH, USA.
Objective: Syncope is common among pediatric patients and is rarely pathologic. The mechanisms for symptoms during exercise are less well understood than the resting mechanisms. Additionally, inert gas rebreathing analysis, a non-invasive examination of haemodynamics including cardiac output, has not previously been studied in youth with neurocardiogenic syncope.

Department of Health and Care Professions, Faculty of Health and Life Sciences, University of Exeter, Exeter, U.K.;
Background: Coronary artery disease (CAD), primarily caused by atherosclerosis, is a leading cause of death, presenting as angina or myocardial infarction. Advances in cardiac imaging, angiography, and procedures like percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) surgery have improved early detection and management of this condition. This report presents the case of a man who experienced worsening exertional chest pain and discomfort while at rest.

Introduction: Venous thromboembolism (VTE) rarely presents with dizziness as the primary complaint, which can delay diagnosis. We report a rare case of dizziness as the chief complaint for a clot-in-transit and extensive bilateral pulmonary emboli.
Case Description: A 70-year-old woman presented to the emergency room (ER) with dizziness and a fall, without reporting loss of consciousness.
Meta-Analysis on the Racial Disparity of Outcomes Following Alcohol Septal Ablation in Hypertrophic Cardiomyopathy.
Cardiol Rev
November 2024
Department of Internal Medicine, University of Pittsburgh Medical Center, Harrisburg, PA.
Hypertrophic cardiomyopathy (HCM) is a prevalent cardiac condition that often leads to heart failure, exertional syncope, and sudden cardiac death. Despite the availability of various treatments for HCM, such as septal reduction therapy through surgical septal myectomy or alcohol septal ablation (ASA), disparities in access to care and treatment outcomes persist, particularly among marginalized racial and ethnic groups. These disparities underscore the importance of understanding the influence of race, ethnicity, and regional factors on the management and outcomes of HCM, necessitating a closer examination of whether access to ASA and its associated benefits is equitably distributed across diverse populations.

Severe heatwaves can lead to extremely high environmental temperatures and a spurt of cases of heat-related illnesses and heatstroke. The incidence of such heat-related medical emergencies was much higher in 2024 compared to previous years throughout North and Central India.
