RESUMO
Cardiovascular complications are major sources of morbidity and mortality in hypertensive patients. To assess the prevalence of anatomical and functional abnormalities of the heart in such patients, we studied total 67 sujects with systemic hypertension and hypertensive cardiovascular disease by echocardiography. Accordingly normal values of echocardiography from 27 control subjects, we found each significant change(p<0.05). of the septal thickness, left ventricular mass, mitral valve E-F slope and aortic dimension on the both groups, but functional measurements did only show significant change on the hypertensive cardiovascular group in contrast to hypertensive subjects group. The prevalence of the echocardiographic abnormalities on the simple hypertensive subjects group who have no abnormal 12-lead E.C.G. or Chest X-rays are orderly 14 subjects(64%) on the aortic root dimension, 9 subjects (41%) on the left ventricular posterior free-wall thickness and 7 subjects(32%) on the septal thickness. These findings demonstrated a high prevalence of cardiac abnormalities in a population of asymptomatic hypertensive subjects. And these abnormalities can be detected well by echocardiography before they were otherwise apparent.
