Ankle-brachial Index and associated factors in individuals with coronary artery disease

Abstract

Objective: Analyzing the association between ABI and the main risk factors for coronary artery disease in coronary patients. Methods: Were selected 156 adult patients from a hospital in Maceio, Alagoas. Were evaluated with risk factors age, obesity, hypertension, diabetes mellitus, smoking, and dyslipidemia. PAOD screening was performed by the ankle-brachial index (ABI). The Mann-Whitney, chi-square, and Fisher's exact tests were used. Confidence Interval of 95% and a significance of 5%. Results: 67.3% (n=105) males, 52.6% (n=82) elderly, 23.1% (n = 34) obese, 72.4% 6% (n=113) hypertensive, 34.6% (n=54) diabetics, 53.2% (n=83) smokers, 34.6% (n=54) dyslipidemic and 70.5% (n=110) with a family history of CAD. 16.7% (n=26) of the individuals presented PAOD. Three factors were associated with PAOD: age group ≥ 60 years (OR:3.656; p=0.005), diabetes mellitus (OR:2.625; p=0.024) and hypertension (OR:5.528; p=0.008). No significant difference was observed in the variables smoking, dyslipidemia, family history of CAD, and obesity. Conclusion: The independent risk factors for PAOD were age, diabetes mellitus, and systemic arterial hypertension.
