ABSTRACT

Myocardial hypertrophy is an adaptative mechanism that allows systolic parietal stress to normalize when the heart has to contract against a higher normal pressure (systolic overload), or the diastolic stress when the normal diastolic volume is higher (diastolic overload). That allows the heart to maintain a normal cardiac waste before such hemodynamic overloads. When neurohumoral mechanisms (adrenergic and renin-angiotensin-aldosterone system) are activated by any reason, myocardial interstice augments its collagen tissue and that causes diastolic dysfunction, myocardial ischemia and cardiac failure.
