Myocardial hypertrophy is associated with progressive contractile dysfunction, increased vulnerability to ischemia-reperfusion injury, and is, therefore, a risk factor in cardiac surgery. During the progression of hypertrophy, a mismatch develops between the number of capillaries and cardiomyocytes per unit area, suggesting an increase in diffusion distance and the potential for limited supply of oxygen and nutrients. We hypothesized that promoting angiogenesis in hypertrophied hearts increases microvascular density, thereby improves tissue perfusion and substrate availability, maintains myocardial function, and improves postischemic recovery.
