چکیده
BACKGROUND: Atherosclerosis is the commonest cause of vascular disease which can involve peripheral and/or cardiac vessels. This study was conducted to evaluate the possible link between Ankle-Brachial Index (ABI) and coronary vessel involvement in patients with stable angina. METHODS: This cross-sectional study was conducted in ۲۰۰۸ on ۱۲۰ individuals who were hospitalized in Chamran Heart Center and underwent coronary angiography. A questionnaire was completed to obtain demographic information, history of previous heart disease and smoking. Body height and weight, as blood pressure on hand and foot were measured. The patients underwent angiography and the extent of coronary involvement (> ۷۵%) was determined. After۱۲-۱۴-hour of fasting, blood sugar was obtained to measure total cholesterol, triglyceride, low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C). The Ankle Brachial Pressure Index (ABI) was calculated as the ratio of the blood pressure in the ankles to the blood pressure in the arms. The data were analyzed by SPSS-۱۵ using ANOVA, T-Student test, Spearman's rank correlation coefficient, and discriminant analysis. RESULTS: Samples were ۴۶ women (۳۸.۳۳%) and ۷۴ men (۶۱.۶۷%) with a mean age of ۵۵.۵۰ ± ۱۰.۴۹. Mean and SD of ABI in men and women was ۰.۷۲ ± ۰.۲۰ and ۰.۸۰ ± ۰.۱۹ with no significant difference (p = ۰.۰۱۲). The correlation between ABI and extent of coronary involvement was ۰.۴۷ (p < ۰.۰۰۰۱). The group with lower ABI had the highest levels of coronary involvement (triple vessel, p < ۰.۰۵). CONCLUSION: ABI had a significant relationship with the degree of coronary involvement and a significant predictive value. Therefore ABI seems to be a reliable indicator of high coronary risk. Keywords: Ankle to brachial index, Coronary involvement, Stable angina.کلیدواژه ها
