 Demographic characteristics of subjects according to ACE I/D genotypes

ACE genotype
II (n = 1473)ID (n = 3358)DD (n = 1883)
Continuous values are mean (SD). ACE, angiotensin converting enzyme; BP, blood pressure; HDL, high density lipoprotein; I/D, insertion/deletion; IMT, intima media thickness; MI, myocardial infarction.
*p<0.05 compared to II genotype; †hypertension defined as SBP⩾160 mm Hg or DBP⩾100 mm Hg or medication use; ‡MI verified by cardiologist, general practitioner, or electrocardiogram.
