Bijan Zamani, Firouz Amani, Faranak Hadeei


Background: Regarding the high prevalence, the increasing trend of acute coronary syndrome (ACS), the importance of etiological studies of diseases and the existence of some reports on the role of blood groups in the development of diseases, including IHD, in order to study the blood groups in patients with acute coronary syndrome and other factors, this research was conducted in Ardabil.

Methods: This is a descriptive study that was carried out from March 2016 to May 2017 in a Hospital of Ardabil on 500 patients selected randomly from patients admitted to cardiac care unit of Hospital. The criteria for entering the study were: All subjects over the age of 30 and both sexes were males and females who had myocardial infarction (MI), unstable angina (UA) based on history, examination, serial electrocardiography and measurement cardiac enzymes are given by a specialist physician and they are willing to participate in the study. Then, in the checklist for each patient, the blood type ABO and RH, the age, sex, and risk factors of the disease such as hypertension, diabetes, obesity, consumption smoking, high blood lipids, and family history of premature stenosis were extracted from the patient records and then analyzes by statistical methods in SPSS.19.  

Results: Of all patients, 60.2% were male and the mean age was 62.28 years. Hypertension with 61.6%, smoking with 37.4%, and hyperlipidemia with 23.4% were the most common risk factors among patients. The blood groups A and A+ were the most common type of blood type, but due to the higher prevalence of A blood group in healthy individuals living in Ardabil, there was no significant relation between ACS and blood groups.

Conclusions: Results showed that blood groups did not show a meaningful relationship with the incidence of ACS and did not find any association between severity of this syndrome and blood groups.
