Increase in left ventricular chamber stiffness in patients with non-insulin dependent diabetes mellitus.
Indices of left ventricular ejection and diastolic filling were measured by cineventriculography in 11 patients with non-insulin dependent diabetes mellitus without significant coronary stenosis and 11 control subjects without diabetes mellitus. Indices of left ventricular ejection, such as ejection fraction and peak ejection rate, were the same in the two groups. The left ventricular end-diastolic volume index and the rapid filling volume index were significantly smaller, the peak filling rate was lower, the left ventricular end-diastolic pressure was higher and the modulus of left ventricular chamber stiffness was larger in the diabetic patients than in the control subjects. These results indicate that left ventricular chamber stiffness is increased in patients with non-insulin dependent diabetes mellitus.
