Frequency of Myocardial Infarction with the Frame of ABO Blood Group System
Keywords:ABO Blood group, Myocardial infarction
Background: The ABO blood group exhibits a blood cell surface protein and an endothelial cell-associated Willebrand factor, and there is evidence that the blood type of individuals can determine the risk of thrombosis in advance. Due to the importance and high prevalence of coronary artery disease, the association between myocardial infarction and ABO blood groups has not been proven, and there are even controversial.
Results. Aims: To determine the relationship between the ABO blood group and acute myocardial infarction.
Materials and Methods: It was a cross-sectional descriptive study carried out at the department of Transfusion Medicine, Bangabandhu Sheikh Mujib Medical University, Dhaka. A total of 384 patients with a history of infarction as the sample. Purposive sampling was applied for the selection of data. The collected data were organized and analyzed using SPSS-22.
Results: Mean age was 54.34±17.26 years, from 25-73 years. Most of the patients, 182 (47.4%) within the 45-65 age group. More than one-third of patients, 295 (76.8%), were male, and 89 (23.2%) patients were female; the male: female ratio was near about 3:1. The association of blood group between STEMI and NSTEMI patients in males and females patients was not statistically significant (p>0.05). However, the prevalence of MI in blood group O is more significantly associated with NSTEMI and STEMI patients than in all other ABO blood groups.
Conclusion: The study shows the relation between the ABO blood group and MI, where patients with the O group are more prone to STEMI and NSTEMI.
