Aims: This study aimed to explore the rapid effects of dapagliflozin in heart failure with reduced ejection fraction (HFrEF).

Methods And Results: We studied the functional, echocardiographic, electrophysiological, lung ultrasound, ambulatory blood pressure (BP), microvascular and macrovascular function, and biochemical effects of 2 week treatment with dapagliflozin in 19 type 2 diabetic HFrEF patients in a double-blind, crossover, placebo-controlled trial. Dapagliflozin had no significant effect on clinical, functional, or quality of life parameters.

Background: Extreme levels of both strength and aerobic training result in increased left ventricular (LV) and right ventricular (RV) volumes and LV mass, a key component of athletes' heart. The aim of this study was to document temporal changes in the hearts of elite professional athletes (Australian Football League players) over a 2- to 6-year period.

Methods: Thirty-six Australian Football League players with 3.

High-dose dobutamine used in dobutamine stress echocardiography (DSE) has hemodynamically based side effects due to a variable combination of beta1 (inotropic) and beta2 (vasodilator) effects. Of concern is the development of an "empty ventricle syndrome" associated with intracavitary or outflow tract obstruction and resultant symptomatic hypotension. This study was undertaken to determine whether the concurrent administration of normal saline (N/S) would decrease symptoms, limit the development of left ventricular outflow tract (LVOT) obstruction and hypotension by maintaining left ventricular volume.
