Properties of transmitral and aortic flow velocities of 32 patients were compared with 17 controls in order to evaluate systolic and diastolic abnormalities in systemic hypertension. It was observed that early and filling peak velocities and their rates were abnormal in hypertensive patients in transmitral flow samples determined by Doppler. It was ascertained that there was a significant increase in AVP (p<0.0005) and a significant decrease in E/A ratio (p<0.0005). In addition, decrease in compliance with rapid filling and increase in atrial filling time (AET) with a greater atrial volume percentile (AFV/TFV) were found (p<0.05,p<0.0005). Increase in isovolumic relaxation time (IRT) (p<0.0005) and decrease in rapid filling index (RFI) were observed from other diastolic function data (p<0.0005). An increase in aortic peak velocity and peak gradient was found. On the other hand, it was observed that the systolic function parameters, peak acceleration (PA), isovolumic index (IVI) and left ventricular ejection time index (LVETI) increased significantly (pa<0.0005,p<0.005,p<0.005; respectively). In both groups, in respect to age, aortic peak velocity increased, E/A rate decreased. In hypertensive patients, early and Iate diastolic peak velocities and their rates and peak aortic velocity were found abnormal. These values when correlated with age were abnormal in both groups. Cardiac functional abnormalities can be detected noninvasively by Doppler.
