Abstract
Introduction: The Ankle Brachial Index (ABI) is a noninvasive and effective measure in the evaluation of peripheral vascular disease, also being indicative of atherosclerosis. This measure is based on the ratio of ankle systolic pressure values to ipsilateral arm systolic pressure. ABI values below 0.90 are considered risk factors for coronary and cerebrovascular diseases and for the presence of high cardiovascular risk. Objective: To describe the ABI and risk factors (RF) of participants in a cross-sectional sample of diabetic and hypertensive patients at high cardiovascular risk. Method: After analyzing a group of 147 high-risk cardiovascular patients, 25.9% of hypertensive diabetic patients (n = 38) were selected for ABI and the demographic profile analysis, related to the presence of brain and/or cardiovascular events (CVD). To evaluate the project, a cross-sectional descriptive analysis of data collected through questionnaires and anthropometric evaluation was used Results: Of the 38 subjects (57.9% women), with a mean age of 63 ± 9 years, other RF history were found: physical inactivity (73.7%); dyslipidemia (63.2%); family history of cardiovascular diseases (60.5%); reports of previous cardiovascular events, myocardial infarction and / or stroke (71.1%); overweight (34.2%); obesity (36.8%) and smoking (7.9%). When comparing the ITB values found in the subgroup with CVD (n = 27) and without CVD (n = 11), we observed values of 1.00 (0.73-1.25) x 1.02 (0.68- 1.13), respectively, with significant difference between the groups by the chi-square Monte Carlo analysis (p 0.13), although with a small analysis sample. Conclusion: In a population with a high cardiovascular profile, with multiple risk factors, the assessment of ABI was a risk marker in the presence of previous CVD, and should be a method to be encouraged in daily clinical practice as a possible marker of cardiovascular risk in the diabetic population.
