title: Association of angiotensin II type I and type II receptor genes polymorphisms with the presence of premature coronary disease and metabolic syndrome.
abstract: Premature coronary artery disease (PCAD) is known to have a particularly strong genetic component. We aimed to investigate the association between angiotensin II receptor type 1 (ATR1) or type II (ATR2) genes polymorphisms and PCAD with or without metabolic syndrome in males. 132 male patients with PCAD and 132 controls were included in the study. ATR1 and ATR2 genes polymorphisms were analyzed by polymerase chain reaction. The present study revealed that ATR1 CC genotype and ATR2 G allele increased the risk of PCAD by 2.9 and 1.3 respectively as well as they increased susceptibility to metabolic syndrome by 4.5 and 2.3 respectively. The present study proved that diabetes, smoking, obesity, total cholesterol, triglycerides, LDLc and HDLc were independent risk factors for the development of PCAD. We concluded that ATR1 CC genotype and ATR2 G allele increased the susceptibility of Egyptian males to have PCAD. The increased susceptibility to have metabolic syndrome could be one of the mechanisms leading to the development of PCAD in subjects carrying one or both of these polymorphisms.
