title: Causes of death of diabetic patients in the past 10 years and their ECG findings.
abstract: We investigated the causes of death of 98 subjects with diabetes mellitus over the past 10 years at our hospital. As was expected, the cause with the highest incidence (48.0%) was vascular disease including cerebral vascular disease (20.4%), coronary heart disease (15.3%), aortic disease and miscellaneous (3.1%), followed by malignant tumors (39.8%), infectious diseases (4.1%) and other diseases. Only one patient died from diabetic coma. The abnormal ECG findings of these patients were analyzed according to the Minnesota Code and 57%, 31%, 26%, 24%, 19% of them showed arrhythmias, ST-T abnormalities, LVH, VPC, and abnormal Q-wave, respectively. These findings showed no statistical difference between diabetics and non-diabetics. Abnormal p-wave, especially LA-load was found more often in diabetics (35%) than in non-diabetics (21%). Q-T interval corrected by Bazett's formula (Q-Tc) was 430 +/- 3.03 (M +/- SEM) msec in diabetics and it was significantly longer (p less than 0.01) than 417 +/- 3.73 msec in patients with other diseases.
