A 34-year-old woman at 18 weeks' gestation experienced shortness of breath and palpitations after receiving her first dose of doxorubicin for right-sided invasive ductal breast carcinoma. Telemetry monitoring found frequent runs of nonsustained ventricular tachycardia that was treated with metoprolol tartrate. No further arrhythmias occurred with subsequent doses of chemotherapy.

Women with obstructive coronary artery disease (CAD) have a relatively lower quality of life (QoL) compared to men, but our understanding of sex differences in QoL in ischemia with no obstructive coronary artery disease (INOCA) is limited. We conducted a survey of patient members of INOCA International with an assessment of self-reported health measures. Functional capacity was retrospectively estimated using the Duke Activity Status Index (DASI), assessing levels of activities performed before and after INOCA symptom onset.

Introduction: Educational attainment is an important social determinant of health (SDOH) for cardiovascular disease (CVD). However, the association between educational attainment and all-cause and CVD mortality has not been longitudinally evaluated on a population-level in the US, especially in individuals with atherosclerotic cardiovascular disease (ASCVD). In this nationally representative study, we assessed the association between educational attainment and the risk of all-cause and cardiovascular (CVD) mortality in the general adult population and in adults with ASCVD in the US.

Ischemia with no obstructive arteries (INOCA) is defined as patients with angiographic evidence of ischemia but no obstructive coronary artery disease (CAD) at coronary angiography. INOCA is estimated to be prevalent is 3-4 million individuals with a female predominance. INOCA is composed of different endotypes including: microvascular dysfunction, vasospasm and a combination of the 2.

Background: There is limited information available regarding evidence of ischemia with no obstructive coronary arteries (INOCA) and quality of life.

Purpose: To determine associations between INOCA and self-reported physical, social, and mental health.

Methods: We conducted a survey of all members (n = 1579) of the INOCA International patient support group.

Giant cell arteritis (GCA) is an inflammatory cranial and/or extracranial vasculitis. Although cranial GCA is widely recognized, extracranial GCA is underdiagnosed because of its nonspecific and atypical presentations. We report a case of asymptomatic extracranial GCA with ascending thoracic aortopathy discovered incidentally during surgical mitral valve repair.

Article Synopsis
  • Loperamide can cause heart problems by blocking potassium channels, which slows down the heart's electrical signals and may lead to serious arrhythmias like long QT syndrome.
  • A case study highlighted a 25-year-old woman with a history of sudden cardiac arrest and opioid use, showcasing how loperamide triggered dangerous heart rhythms due to an underlying condition called apical hypertrophic cardiomyopathy (AHCM).
  • It's crucial to investigate structural heart issues in patients with sudden cardiac arrest, as this can identify potential risks and allow for better treatment options, including genetic assessment for those with AHCM.

Background: Achalasia is an uncommon disease treated by decreasing the lower esophageal sphincter resting pressure. This study compared the safety and efficacy of esophago-gastric myotomy via laparoscopic, robotic, and per-oral endoscopic approaches.

Methods: A retrospective review of data on patients with achalasia or other esophageal dysmotility disorder undergoing laparoscopic, robotically assisted, or per-oral endoscopic myotomy (POEM) procedures between 2013 and 2017 was performed.
