title: [Polymorphic markers I/D and G7831A of angiotensin-I-converting enzyme gene and left ventricular hypertrophy in patients with essential hypertension].
abstract: OBJECTIVE
  To elucidate possible association of angiotensin-I-converting enzyme (ACE) gene polymorphic markers I/D and G7831A with left ventricular hypertrophy (LVH) in patients with essential hypertension.
  
  
  METHODS
  Patients with essential hypertension (n=123, 37 with and 86 without LVH, mean age 59.15+/-1.19 years).
  
  
  METHODS
  Left ventricular (LV) mass was determined echocardiographically by Devereux method. Alleles and genotypes of ACE gene polymorphic markers were identified by polymerase chain reaction.
  
  
  CONCLUSIONS
  There was no association between I/D marker of ACE gene and LVH. Carriers of A allele compared with carriers of G allele of G7831A marker had significantly higher LV mass (284.1+/-10.20 g, and 248.5+/-14.42 g, respectively, p=0.033) and LV mass index (151.7+/-5.23 g/m2 and 131.0+/-6.74 g/m2, respectively; p=0.02). Among patients with LVH frequency of A allele was significantly higher than among patients without LVH (0.401 and 0.230, respectively; p=0.0065, OR=2.116 [1.197-3.7481]). Using binary logistic regression model we have found that presence of LVH was linked with age, sex and maximal systolic blood pressure (BP). Such factors as smoking, maximal diastolic BP, ordinary systolic and diastolic BP, duration of hypertension, coronary artery disease and diabetes were not related to LV mass index. Using multifactorial logistic regression model we have found that the presence of A allele of G7831A polymorphic marker of ACE gene, age and maximal systolic BP could be considered as independent risk factors of LVH.
