Abstract
The role of impaired diastolic function in determining the pathophysiology of congestive cardiomyopathy was only recently appreciated. In the present study, echocardiography and Doppler cardiography were used to determine changes in cardiac size and transmitral filling dynamics over a 1-year period in patients with congestive cardiomyopathy and determine the effect of captopril on these changes. The study population consisted of 27 patients with congestive heart failure in spite of therapy with digitalis and diuretics (NYHA class 3.2). Fifteen patients were started on placebo and 12 on captopril. Noninvasive evaluation was performed at 6-month intervals. Left ventricular size and left ventricular ejection fraction did not change significantly in either group. Forward stroke volume improved significantly only in patients on captopril compared to placebo (p < 0.05). No significant changes in transmitral flow dynamics were observed in the placebo group whereas the captopril-treated group showed a decrease in the peak velocity, flow velocity integral and rate of rapid filling wave (E) and an increase in the peak, integral and rate of filling during atrial contraction (A). The E/A ratio did not change significantly over time in the placebo group, whereas a reduction in the ratio was noted in the captopril-treated patients. These changes are sustained over 1 year with concomitant improvement in stroke volume, exercise duration and functional class.
