Angiotensin II type 1 receptor gene A1166C polymorphism was not associated with acute coronary syndrome in an Iranian population

الملخص EN

Background : There are very limited data for Iranian populations on the predisposing genetic factors for acute coronary syndrome (ACS).

Objectives : The objective of the present study was to investigate the association of the angiotensin II type 1 receptor (AT1R) gene polymorphism and ACS in an Iranian population.

Patients and Methods : This cross-sectional study was conducted among 263 subjects (97 men and 166 women).

Patients (n = 128) aged 30 - 80 years with chest pain were recruited from the emergency department of Ghaem Hospital (Mashhad, Iran).

A 12-lead electrocardiograph plus creatine kinase MB (CK-MB) levels were used as the basis for the diagnosis of myocardial ischemia.

The control group was selected from age-matched healthy subjects (n = 135).

Non-enzymatic kits were used for extraction of DNA from blood samples.

Polymerase chain reaction (PCR) was performed to amplify the DNA fragments.

For restriction fragment length polymorphism (RFLP) determination, the DdeI enzyme was used to digest the amplified DNA fragments.

Statistical analyses were performed using SPSS version 13.0.

Results : There wasnostatistical difference in the genotype frequency of patients and healthy subjects with regard to age and gender (P > 0.05).

Conclusions : The AT1R A1166C polymorphism appeared not to be associated with the presence of ACS in the population studied.
