Echocardiographic Assessment of Young Male Draft-Eligible Elite Hockey Players Invited to the Medical and Fitness Combine by the National Hockey League.

The "athletic heart" is characterized by hypertrophy and dilation of the heart, in addition to functional and electrical remodeling. The aim of this study was to provide reference 2-dimensional (2DE) and 3-dimensional (3DE) echocardiographic measurements in a large database on draft-eligible elite ice hockey players and to determine the frequency of occult cardiac anomalies in this cohort of athletes. In this prospective cohort study, we performed a comprehensive cardiac assessment of the 100 top draft picks selected by the National Hockey League.

DPP-4 inhibition attenuates cardiac dysfunction and adverse remodeling following myocardial infarction in rats with experimental diabetes.

Aims: Following myocardial infarction (MI), individuals with diabetes have a two-fold increase in the risk of heart failure, due in part to excessive loss of cardiac microvasculature. Endothelial integrity and restitution are mediated in part by stromal cell-derived factor-1α (SDF-1α), a chemokine that is elaborated by ischemic tissue but rapidly degraded by dipeptidyl peptidase-4 (DPP-4). Accordingly, we hypothesized that inhibiting this enzyme may confer benefit following myocardial infarction in the diabetic setting beyond its effect on glycemia.
