    Abstract:
    To determine if impairment of left ventricular filling is influenced by acute myocardial infarction in patients with arterial hypertension, left ventricular diastolic function was assessed by pulsed doppler echocardiography in 46 patients (pts) subdivided into four groups (Gr): G.1 (n = 12 pts) with acute myocardial infarction and hypertensive heart disease. G.2 (n = 12 pts) acute myocardial infarction without arterial hypertension. G.3 (n = 10 pts) arterial hypertension without history of coronary artery disease. G.4 (n = 12 pts) healthy subjects. Coronary angiography and left ventricular cineangiogram was performed in 24 pts (G.1 + G.2). Peak mitral flow velocity (cm/s) in early diastole (E), atrial systole (A), A/E and int A/int E ratios were measured by pulsed doppler. Age and heart rate were statistically similar in all groups. No difference was found among G.1 and G.2 in ejection fraction, and left ventricular segmental kinetic. (tables; see text) Conclusion left ventricular filling is impaired in pts with arterial hypertension and in pts with acute myocardial infarction; acute myocardial infarction increase the impairment of left ventricular diastolic function in pts with hypertensive heart disease.
