Ankle/arm pressure index in asymptomatic middle-aged males: an independent predictor of ten-year coronary heart disease mortality.

Purpose of the study: to evaluate the predictive power of a reduced ankle/brachial pressure index (ABPI) (≤ .90) in an asymptomatic middle-aged male working population free of coronary heart disease.Materials and Methods: 2023 subjects forty to fifty-five years old were screened at their work place. Standard techniques were used. Blood was drawn in the fasting state. Ankle and brachial blood pressures were measured by Doppler signals and all measures were done by one observer, duly trained in epidemiologic methodologyResults: in univariate analysis, an ABPI ≤ .90 was significantly associated with age, total serum cholesterol, body mass index, smoking, and awareness of diabetes. In multi- variate analysis, it was associated with awareness of diabetes, age, Ln triglycerides (P=.073), and smoking (P=.088).Relative risks for reduced versus normal ABPI are 2.77 (P=.010), 4.16 (P=.011) and 4.97 (P=.006) for ten-year all causes, cardiovascular, and coronary mortality, respec tively. In a multiple logistic regres...
