Low risk of coronary heart disease in female type II diabetic subjects with diabetic relatives.
Possible risk factors for cardiovascular disease were studied in 52 type II diabetic subjects, 19 with and 33 without a history of coronary heart disease (CHD). None of the recognized risk factors, such as hypertension, hyperlipidaemia, smoking and blood glucose imbalance, could be related to CHD. However, all female patients with CHD were lacking a family history of diabetes, while seven of nine female diabetic subjects without a history of CHD had diabetes in the family (p less than 0.02). This was confirmed in a second study of 150 type II diabetic subjects; CHD was more common among female patients without compared to those with diabetes in the family; 9/38 and 1/28, respectively (p less than 0.03). Diabetes increases the risk of CHD, and it does so for women more than it does for men. The finding of a possible low CHD risk in female diabetic subjects with diabetes in the family supports the hypothesis of genetic factors being important for the pathogenesis of cardiovascular disease in diabetes mellitus.
