[Correlation between ABO and Rh blood groups, serum cholesterol and ischemic heart disease in patients undergoing coronarography].

Unlabelled: The associations of the ABO- and Rh-blood groups, the serum cholesterol and the extent of the coronary artery disease were examined in 653 patients who underwent coronary angiography between 1980 and 1985 in the Hungarian Institute of Cardiology.
Conclusions: 1. among the patients with positive coronarography blood group A was more frequent and blood group 0 was less frequent than in the Hungarian population, 2. in the blood group 0 the left main stenosis, in the blood group AB the single-vessel-disease was significantly more frequent, 3. the mean serum cholesterol level was almost identical in the ABO-blood groups, but in the Rh-negative patients it was significantly higher, showed no difference according to age, but closely correlated with the extent of coronary artery disease.
