Aging effects on myocardial hypertrophic response and coronary circulation in pressure-overload.


We examined the effect of age on capacity for myocardial hypertrophy, pressure-generating ability and coronary circulation after imposition of pressure-overload. Marked right ventricular and cellular hypertrophy was observed 1 week after pulmonary artery constriction in the developmental phase of rats (2 months of age) and after 3 weeks in the young-adult… (More)
