Cardiovascular risk-enhancing factors and coronary artery calcium in South Asian American adults: The MASALA study.

Objectives: The 2018 and 2019 U.S. guidelines for the management of cholesterol and primary prevention of atherosclerotic cardiovascular disease (ASCVD) recommend consideration of cardiovascular risk-enhancing factors (REFs), including South Asian ancestry, to refine ASCVD risk estimation.

ST-segment Elevation Myocardial Infarction Resulting from Stent Thrombosis in Contemporary Real-World Practice.

Stent thrombosis (ST) is a rare but devastating complication after percutaneous coronary intervention. Newer generation drug-eluting stents (DES) and newer antiplatelet therapies have been shown to decrease the incidence of ST, but we continue to observe ST-segment elevation myocardial infarction (STEMI) due to ST in contemporary practice. A retrospective analysis of 527 patients who presented with STEMI was performed; 57 patients (11%) with angiographically confirmed ST were compared with the patients with STEMI due to de novo lesion.

Activin C antagonizes activin A in vitro and overexpression leads to pathologies in vivo.

Activin A is a potent growth and differentiation factor whose synthesis and bioactivity are tightly regulated. Both follistatin binding and inhibin subunit heterodimerization block access to the activin receptor and/or receptor activation. We postulated that the activin-beta(C) subunit provides another mechanism regulating activin bioactivity.
