Abstract

Computerized M-mode echocardiography was used to evaluate left ventricular anatomy and function in 20 patients with hypertension and diabetes mellitus, without signs of overt heart disease. A similar study was performed in 20 patients with hypertension of similar severity and duration and in 20 normal subjects. Mean posterior wall thickness and mean septal thickness were increased in hypertensive patients compared to normal (p <0.001), but diabetic patients had thicker septa with respect to nondiabetics (p <0.05). All hypertensive- diabetic patients had reduced peak lengthening rate and/or peak velocity of posterior wall thinning. Six of them also had reduced peak Vcf and/or peak velocity of posterior wall thick-ening. Only 9 of the 20 patients with hypertension alone had abnormal diastolic function; 4 out of these 9 also had abnormal systolic function. We conclude that diabetes causes more severe impairment of left ventricular function in patients with a similar degree of hyperten-sion. The more consistent abnormalities are reduced rate of dimension increase during filling and slower wall thinning, suggesting impaired left ventricular relaxation and distensibility.
