WebSep 6, 2024 · Milrinone is a medication indicated for cardiac support in patients with acute heart failure, pulmonary hypertension, or chronic heart failure. It improves cardiac contractility (inotropy) and cardiac relaxation (lusitropy) and induces vasodilation. It has the overall effect of increased cardiac output, improved left ventricle-arterial coupling ... WebIsoproterenol is an extremely potent β 1 - and β 2- agonist that possesses no α-stimulating properties. Therefore isoproterenol increases heart rate, automaticity, and contractility and dilates both venous capacitance and arterial vessels. It may be a good choice for heart-rate maintenance in a denervated nonpaced transplanted heart.
Web1. Preload. Definition: the stretch of the cardiomyocytes at the end of diastole. It is often referred to as ventricular filling or the volume in the left ventricle at the end of diastole (LVEDV). The definition of preload is significantly different from the way that preload is typically talked about clinically.
