title: [The use of pulsed Doppler in the evaluation of diastolic function in acute ischemic cardiopathy].
abstract: We report the alterations of the left ventricular diastolic function studied with pulsed Doppler echocardiography. We measured different parameters of the transvalvular mitral blood flow in four patients with Unstable Angina Pectoris and six patients with Acute Myocardial Infarction. The results of these patients were compared with the results of a control group of twelve normal subjects. All subjects of study had no previous history of cardiovascular disease. The studied parameters were the acceleration and deceleration half times (t1(2a)/t1(2d), respectively), the diastolic deceleration slope (PD), the maximum velocity of the atrial filling and rapid filling quotient (A/E), and the first third diastolic fraction (FD). We found significant difference in the mean value of the A/E and the FD between the normal subjects and 80% of the patients with Ischemic Heart Disease. We also found significant difference in the other studied parameters between the normal and Unstable Angina groups. We concluded that Acute Ischemic Heart Disease causes significant anomalies of the left ventricular diastolic function and that pulsed Doppler echocardiography is a good method to demonstrate it.
