Sub-clinical diabetic cardiomyopathy - assessment by systolic time intervals

Left ventricular performance in diabetics wit he at hypertension, ischemic Tie art disease, or clinical evidence of other heart diseases was assessed by systolic time intervals and echo-cardiography. The PEP/ LVET ratio was 3.48% higher in diabetics than in controls. There was good correlation of abnormality of PEP/LVET ratio with duration of diabetes. There was no correlation with age of patient or severity of diabetes. There was good correlation between abnormal PEP/LVET and incidence of retinopathy and nephropathy. This suggests the possibility of the presence of subclinical diabetic cardiomyopathy in these individuals.
