Analysis of correlation between acute myocardial infarction with ABO blood type in patients with diabetes

Abstract

Objective To study the relationship between acute myocardial infarction with the distribution of ABO blood type antigen in patients with diabetes. Methods 2 052 patients with diabetes were selected.All patients had blood type records.The patients were divided into A blood type group(n=625), B blood type group(n=548), AB blood type group(n=204), O blood type group(n=675). Records were analyzed for the incidence of acute myocardial infarction. Results (1)The incidence rate of acute myocardial infarction in the A blood type group was 9.44%, which in the B blood type group was 8.03%, whith in the AB blood type group was 6.86%, which in the O blood type group was 5.19%, there was significant difference among the four groups(χ2=9.02, P<0.05). (2)For patients with diabetes, the incidence rate of acute myocardial infarction in the A blood type group was 9.44%, which was significantly higher than 6.52% in the non-A blood type group, the difference was statistically significant(χ2=5.41, P<0.05). (3)For patients with diabetes, the incidence rate of acute myocardial infarction in the non-O blood type group was 8.50%, which was significantly higher than 5.19% in the O blood type group, the difference was statistically significant(χ2=7.24, P<0.05). Conclusion There is a correlation between acute myocardial infarction with ABO blood type in patients with diabetes.For patients with diabetes, the patients with A blood type develop acute myocardial infarction more often than patients with non-A blood type, patients with blood type non-O develop acute myocardial infarction more often than patients with blood type O.
