Abstract

Recently, the proportion of cardiovascular disease as a cause of death in diabetics is in ever increasing tendency.
Present study is designed to evaluate the change of myocardial performance by the effect of microangiopathy of diabetics.
The measurements of systolic time intervals were obtained from simultaneous high speed recordings(100mm/sec) of electrocardiography, phonocardiography, and carotid pulse tracing in diabetics(male 26, female 31).
1. As the diabetic retinopathy got severe, shortening of LVET and prologation of PEP were noted, but QS2 showed no significant change.
2. PEP/LVET ratio fo diabetics without diabetic retinopathy was significantly higher than that of normal control(p<0.01).
3. PEP/LVET ratio of diabetics with diastolic blood pressure under 95mmHg was significantly higher than that of normal control group(p<0.01), and PEP/LVET ratio of diabetics with diastolic blood pressure over 96mmHg was significantly higher than that of normal control and that of diabetics with diastolic blood pressure under 95mmHg(p<0.01).
4. PEP/LVET ratio of diabetics with proliperative retinopathy was significantly higher than that of normal control and that of diabetics with mild diabetic retinopathy(p<0.01), but this result was not conclusive because of the small case number.
