[Changes of left ventricular diastolic function in hypertensive patients with left atrial enlargement].
In order to find out the relationship between the left atrial enlargement and left ventricular diastolic function in hypertension, radionuclide ventriculography was performed in 45 hypertensive patients with normal left ventricular mass index(LVMI), including 23 with normal left atrium(Group I), 22 with left atrial enlargement(Group II), and 28 matched subjects as control(Group III). The results showed that the left ventricular diastolic function in Group I was normal, but abnormal in Group II. It is considered that left atrial enlargement and left ventricular diastolic dysfunction are the early signs of the hypertensive heart disease.
