This study was conducted to explore whether the renin C-5312T, angiotensin II type 1 receptor A1166C, and angiotensin-converting enzyme I/D polymorphisms were associated with ambulatory blood pressure (BP) and central hemodynamics in an untreated hypertensive population. A total of 471 participants with no previous treatment for raised BP were eligible for the study. Ambulatory and central BP were measured. DD carriers had the highest daytime systolic/diastolic BP, nighttime systolic BP, 24-hour systolic BP, and 24-hour diastolic BP values, whereas carriers of DD had higher central systolic BP and augmentation index compared with those with the II genotype. Multivariate regression analysis demonstrated that DD genotype was independently associated with 24-hour systolic BP, 24-hour diastolic BP, central systolic BP, and central augmentation index. There was an independent association of the angiotensin-converting enzyme polymorphism with central and ambulatory BP in Chinese patients with hypertension. [ABSTRACT FROM AUTHOR]
