| Popis: | AIM: To study the impact of angiotensinogen (AGT) and angiotensin II receptor type 1 (AGTR1) gene polymorphisms on the development and course of chronic heart failure (CHF) in patients with coronary heart disease (CHD)/MATERIAL AND METHODS: Two hundred and twenty-six patients (149 men and 77 women; mean age 55.9±5.8 years) with CHF were examined. Genotypes were identified by the restriction fragment length polymorphism analysis of polymerase chain reaction products. A control group comprised 136 subjects (63 men and 73 women; mean age 53.6±4.8 years) without signs of cardiovascular diseases, as evidenced by the examination/RESULTS: The T allele of the M235T polymorphism in the AGT gene was found to be associated with the development and unfavorable course of CHF in patients with CHD. At the same time, carriage of the M allele of the M235T polymorphism in the AGT gene reflected the favorable course of this disease. That of the C allele and A/C genotype of the A1166C polymorphism in the AGTR1 gene was associated with the development of CHF and the A allele and A/A genotype manifested themselves as protective factors. According to the severity of CHF and the nature of its course, the distribution of frequencies of the genotypes and alleles of the A1166C polymorphism in the AGTR1 gene showed no significant differences between the patient groups/CONCLUSION: There were associations of the polymorphisms of the AGT gene (the M235T polymorphic marker) and the AGTR1 gene (the A1166C polymorphic marker) with the development of CHF in patients with CHD. |
