title: Hypertension and the heart.
abstract: Sustained increase in arterial pressure causes left ventricular hypertrophy and adversely affects all myocardial compartments: myocytes, interstitium, and coronary vasculature. Ventricular hypertrophy significantly increases the risk for cardiovascular morbidity and mortality in hypertensive disease. Impairments in coronary circulation and ventricular fibrosis, which are an essential part of hypertensive disease, contribute to that increased risk. This report discusses the mechanisms of hypertension-induced myocardial collagen accumulation and impairments in coronary hemodynamics. Particular attention is given to the interaction of hypertension and aging because aging aggravates hypertensive changes and the incidence of hypertension increases with aging. The effect of therapy on hypertension-induced ventricular fibrosis and impairment in coronary hemodynamics and the risk associated with these changes are also discussed.
