A naturally occurring mutation in ATP synthase subunit c is associated with increased damage following hypoxia/reoxygenation in STEMI patients.

Cell Rep 2021 Apr;35(2):108983

Maria Cecilia Hospital, GVM Care & Research, 48033 Cotignola, Ravenna, Italy; Department of Medical Sciences, Section of Experimental Medicine, Laboratory for Technologies of Advanced Therapies (LTTA), University of Ferrara, 44121 Ferrara, Italy. Electronic address:

Preclinical models of ischemia/reperfusion injury (RI) demonstrate the deleterious effects of permeability transition pore complex (PTPC) opening in the first minutes upon revascularization of the occluded vessel. The ATP synthase c subunit (Csub) influences PTPC activity in cells, thus impacting tissue injury. A conserved glycine-rich domain in Csub is classified as critical because, when mutated, it modifies ATP synthase properties, protein interaction with the mitochondrial calcium (Ca) uniporter complex, and the conductance of the PTPC.

Stat Med 2021 Apr 13. Epub 2021 Apr 13.

The Biostatistics Center, Department of Biostatistics and Bioinformatics, The George Washington University, Rockville, Maryland, USA.

Time-to-event outcomes are common in clinical studies. For example, the time to a first major adverse cardiovascular event (MACE, defined as CVD death, nonfatal myocardial infarction, or stroke) is a commonly used outcome in cardiovascular outcome trials. Owing to the lengthy time frame and other factors, the high costs of conducting such studies has been identified as one of the major obstacles in conducting clinical trials in the United States.

Management of left ventricular thrombus: a narrative review.

Ann Transl Med 2021 Mar;9(6):520

Heart Failure/Cardiac Transplantation Program, University of California, San Diego, CA, USA.

Left ventricular thrombus (LVT) is a serious complication of acute myocardial infarction (MI) and also non-ischemic cardiomyopathies. We performed a narrative literature review, manual-search of reference lists of included articles and relevant reviews. Our literature review indicates that the incidence of LVT following acute MI has decreased, probably due to improvement in patient care as a result of better and earlier reperfusion techniques.
