Cardiac Contractility

Meaning

Cardiac Contractility, clinically referred to as inotropy, represents the intrinsic strength and force generation capacity of the heart muscle, independent of changes in ventricular filling pressure or afterload. This fundamental mechanical property of the myocardium is a key determinant of stroke volume and overall cardiac output, directly reflecting the heart’s pumping efficiency. Maintaining optimal contractility is absolutely crucial for ensuring robust systemic circulation and the efficient delivery of oxygen and regulatory hormones to all peripheral tissues, which is vital for metabolic and hormonal wellness.
