but heart failure most commonly first begins with left ventricular /systolic failure, which leads to right ventricular failure although signs of heart failure may become more evident with right ventricular failure. Systolic failure (Pumping) Most heart failure derives from systolic failure, or the inability of the heart to

in right heart chamber dimensions. However, less than optimal right ventricular (RV)–arterial coupling may already cause a decreased aerobic exercise capacity by limiting maximum cardiac output. In more advanced stages, RV systolic function cannot remain matched to afterload and dilatation of the right heart chamber progressively develops.

Normal myocardial function in severe right ventricular volume overload hypertrophy. Am J Physiol Heart Circ Physiol 280: H11–H16, 2001.—Severe left ven-tricular volume overloading causes myocardial and cellular contractile dysfunction.

Ventricular remodeling
left ventricular hypertrophy, and diabetes mellitus are the most common culprits leading to heart failure [3,4]. The transition from an index event to overt heart failure is not well understood, but the different causes of cardiac remodeling share common molecu-lar, biochemical, and mechanical pathways. Remod-
