We report an unusual case of coronary-multivascular, small coronary artery embolism by atheromatous elements originating in a plaque in the main right coronary artery of a 52-year-old man who died of acute thrombotic occlusion of the severely stenotic left anterior descending vessel. The embolized arteries showed the characteristic multiphasic inflammatory changes of different ages previously described in arteries occluded by this material. The myocardium supplied by the involved channels showed ischemic damage of varying ages. Both these observations indicate that the multiple emboli had been discharged at different times, rather than as a single shower. Finally, we make a plea for the use of the correct term "erosion" rather than "ulcer" for the lesion that is the source of the invasive obstructions.

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.
