It is a core physiology concept used to describe how strongly the ventricle can contract at a given preload and afterload. Clinically, Contractility is discussed in heart failure, shock, ischemia, and during use of inotropes. It is commonly inferred from bedside findings, echocardiography, and hemodynamic data rather than measured directly."}
