Abstract

The value of a quantitative analysis of the regional systolic and diastolic function in analyzing the myocardial effects of drugs directly administered into coronary vessels was assessed in patients with aortic stenosis during an infusion of an ACE-inhibitor in the left main trunk. The computation of the changes in regional areas, of regional peak filling rate, of an index of regional chambcr stiffness and of the changes in regional area during tsovolumic relaxation revealed a selective improvement of myocardial diastolic function in the perfused territory. As this improvement remained undetected when the global indices of LV function were examined, it is concluded that regional wall motion analysis is indispensable to correctly assess the effects of intracoronary drug administration.
