Myocardial Performance

Meaning

Myocardial Performance is a clinical measure of the functional capacity and efficiency of the heart muscle, the myocardium, specifically its ability to contract, relax, and maintain adequate cardiac output to meet the body’s physiological demands. In the context of hormonal health, this parameter is critically influenced by the balance of circulating hormones, particularly thyroid hormones, androgens, and estrogens, which exert direct trophic and regulatory effects on cardiac tissue. Optimal myocardial performance is a key determinant of cardiovascular longevity and systemic oxygen delivery. Assessment involves metrics like ejection fraction and diastolic function.
