[GENES ALLELE STATUS OF ANGIOTENSINCONVERTING ENZYME (I/D) AND ENDOTHELIAL NITRIC OXIDE SYNTHASE (894 G > T) IN PATIENTS WITH ACUTE CORONARY SYNDROME].

Abstract

The association of genes polymorphism of angiotensin-converting enzyme ACE (I/D) and endothelial nitric oxide synthase eNOS (894 G > T) with acute myocardial infarction (MI) among residents of North Bukovina region was evaluated. II/GG and ID/GG haplotypesre associated with more frequent presence of Q-MI, with localization on anterior wall and primary appearance. ID/TT, or II/TG haplotypes are associated with the presence of a severe re-Q-MI, with localization on the posterior wall. ID/TG variant is associated in 93.7% of cases with Q-MI, regardless of its location and times of occurrence. ID/TG increased relative risk of Q-MI by 2,93 times (OR = 4,79; P = 0,002), which confirmed the severity of the disease and increases the risk of MI inanterior and higher in posterior walls of the left ventricle (OR = 4.31; P = 0.007 and OR = 4.6; P = 0.005, respectively) increases the likelihood of the first Ml by 2.88 times (OR = 4.62; P = 0.003) and its re-occurrence or recurrence--by 2.67 times (OR = 4; P = 0.022). Mutations absence: in haplotypes (II/GG) is a protective factor of Q-MI appearance (OR = 0.19; P = 0.004) and makes the chances for the first MI the lowest in observed population (OR = 0.36; P = 0.045).
