Abstract

Aims of the study has been the evaluation of morphological and functional aspects of left ventricle in subjects undergoing mild hypertension and sport adaptation effects. These evaluations have been carried out by Echo-Doppler both at rest and during sharp increase in after load induced by isometric stress. Together with the morphological parameters represented by mass index and by radius to thickness ratio, we have studied stroke volume and transmitral flow pattern assessing the maximum flow velocity during rapid filling phase (E), during atrial contraction phase (A) and their ratio (E/A). We have studied 31 male subjects from 39 to 60 (average 47) exercising twice or three times a week (in the main, aerobic sports such as road cycling). They were subdivided into two groups, the first included 16 subjects with mild hypertension (AP = 155 +/- 9/97 +/- 5 mmHg) the second included 15 normotensive subjects without known pathologies, comparable for age and body surface (AP = 125 +/- 15/77 +/- 10 mmHg). Hypertensive subjects exercising regularly, showed a mass index (164 +/- 42 g/m2) significantly higher than the controls (139 +/- 35 g/m2, P less than 0.01) but they ke a normal filling pattern at rest and similar stroke volume values. During isometric exercise instead, the velocities of E and A waves showed a different trend in the two groups with a higher reduction in E/A ratio in hypertensive subjects. The per cent decrease in this ratio turned out to be 15% in the control group and 33% in hypertensive subjects (P less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)
