AI Article Synopsis
- A case study presents a 44-year-old pregnant woman with no prior vascular risk factors who developed a spontaneous dissecting aneurysm in her circumflex coronary artery.
- Spontaneous coronary artery dissection is rare, particularly affecting women, especially in the postpartum period, with the left anterior descending artery being the most commonly involved.
- Theories explaining this condition during pregnancy include arterial wall changes, hemodynamic factors, and contributions from immune cells leading to injury in the arterial wall.
Article Abstract
We describe a case of spontaneous dissecting aneurysm of the circumflex coronary artery in a 44-year-old primigravida at term with no vascular risk factors. Spontaneous coronary artery dissection is a very rare condition with a greater prevalence in women, postpartum in particular. The left anterior descending artery is the most frequently affected. Histologically, the most common finding is a hematoma occupying the outer third of the media, resulting in complete compression of the true lumen. Arterial wall changes during pregnancy together with hemodynamic factors, a lytic action of protease released from eosinophils, and intimal tears are the main hypotheses considered to explain the etiology of spontaneous coronary artery dissection.

Racial disparities in extended venous thromboembolism prophylaxis after hysterectomy.
PLoS One
January 2025
Robert Wood Johnson Medical School, Rutgers University, New Brunswick, NJ, United States of America.
Background: Venous thromboembolism (VTE) is a significant preventable cause of postoperative morbidity and mortality after major abdominopelvic surgery that calls for extended VTE prophylaxis (eVTEp). Literature suggests that significant racial disparities may exist in post-operative care.
Objective: The study sought to examine if racial disparities exist in the administration of eVTEp after hysterectomy in a statewide collaborative.
β2-Adrenergic Receptor Agonist Clenbuterol Protects Against Acute Ischemia/Reperfusion-Induced Arrhythmia by Regulation of Akt/eNOS/NO/Cx43 Signaling Pathway.

Ventricular arrhythmias induced by ischemia/reperfusion injury limits the therapeutic effect of early reperfusion therapy for acute myocardial infarction. This study investigated the protective effects of the β2-adrenergic receptor (β2-AR) agonist clenbuterol against ischemia/reperfusion-induced arrhythmias and the underlying mechanism. Anesthetized rats were subjected to 10-min left coronary artery occlusion and 10-min reperfusion in vivo.

Atherosclerosis is one of the leading causes of ischemic cardiovascular disease worldwide. Recent studies indicated that vascular smooth muscle cells (VSMCs) play an indispensable role in the progression of atherosclerosis. Exosomes derived from mesenchymal stem cells (MSCs) have demonstrated promising clinical applications in the treatment of atherosclerosis.
