Abstract

Objective: Angiotensin converting enzyme (ACE) is a key enzyme in angiotensin II production which causes myocardial hypertrophy and hyperplasia. In this study we aimed to investigate the relation between ACE I/D gene polymorphism and left ventricular mass (LVM), dimensions and systolic functions calculated by mitral annular motion (MAM) in young healthy male subjects.Methods: Complete echocardiographic examination was performed in 49 male healthy subjects (mean age 22.9±2.1 years) consisting of 18 ACE DD, 18 ACE DI and 13 ACE II genotypes. We calculated LVM and mass index (LVMI) by M-Mode echocardiography. The systolic MAM was recorded at 4 sites (septal, lateral, anterior, and posterior) by M-mode echocardiography and the MAM-ejection fraction (EF) was calculated from above four sites. Ejection fraction was also calculated by Simpson’s method. Results: There was no significant difference among the three genotypes according to age, body mass index, systolic and diastolic blood pressure and heart rate. Interventricular septum (IVS) and left ventricular posterior wall (LVPW) diastolic thickness, LVM and LVMI were found significantly different among 3 ACE genotypes. Those measurements were higher in DD genotype in comparison to the DI and II genotypes. There was no significant difference among the three genotypes according to EF-MAM and EF by Simpson’s method.Conclusion: In young healthy male subjects having ACE DD genotype, even though LVM and LVMI were within normal limits, their measurements were found to be higher than in subjects with ACE DI and II genotypes respectively. There was no difference among the three genotypes according to left ventricular systolic functions.

Özet

Amaç: Anjiyotensin dönüştürücü enzim (ADE) ile oluşan anjiyotensin II (AII), özellikle anjiyotensin reseptör I üzerinden miyokardda hipertrofi ve hiperplaziye neden olmaktadır. Bu çalışmada ADE DD, DI ve II genotiplerine sahip sağlıklı genç erkeklerde sol ventrikül kitlesi ve boyutları ile mitral annuler hareket (MAH) yöntemiyle sistolik fonksiyonlar ve aralarındaki ilişki araştırılmıştır.Yöntemler: On sekiz ADE DD, 18 ADE DI ve 13 ADE II genotiplerine sahip toplam 49 sağlıklı genç erkekte (ortalama yaş 22.9±2.1 yıl) tam ekokardiyografik inceleme yapıldı. M-mod ekokardiyografi ile sol ventrikül kitlesi (SVK) ve SVK indeksi (SVKİ) hesaplandı. Apikal dört ve iki boşluk pencerelerinde septal, lateral, anteriyor ve posteriyor sistolik MAH ölçümleri yapıldı ve ejeksiyon fraksiyonu (EF) hesaplandı (EF-MAH%). Ayrıca Simpson kuralına göre de sol ventrikül hacimleri ile EF (%) ölçümleri yapıldı. Bulgular: Üç grup arasında yaş, beden kitle indeksi, sistolik ve diyastolik kan basınçları ile kalp hızları açısından anlamlı fark yoktu. Interventriküler septum (İVS) kalınlığı, sol ventrikül arka duvar (SVAD) kalınlığı, SVK ve SVKİ ölçümleri, ADE DD, DI ve II genotipleri arasında anlamlı olarak farklı saptandı. Bu ölçümler, ADE DD genotipinde diğer iki gruba göre anlamlı olarak daha yüksekti. Sol ventrikül ejeksiyon fraksiyonu ise, gerek sistolik MAH yöntemiyle ve gerekse Simpson kuralına göre üç ADE genotipi arasında anlamlı fark oluşturmadı.Sonuç: Anjiyotensin dönüştürücü enzim DD genotipine sahip sağlıklı genç erkeklerde, İVS, SVAD kalınlıkları ile SVK ve SVKİ artmasa bile ADE DI ve II genotipleri gruplarına göre anlamlı olarak daha fazla olmaktadır. Sol ventrikül sistolik fonksiyonlarında ise üç genotip grubu arasında anlamlı fark oluşmamaktadır.
