Prevalência de doença arterial obstrutiva periférica em idosos na cidade de Santa Cruz/RN

Abstract

Aim: to evaluate the prevalence of peripheral arterial occlusive disease (PAOD) in elderly in the city of Santa Cruz/RN. Methods: individuals of both genders, aged between 60 and 80 years registered at the Primary Care Facility of Santa Cruz were invited to participate of the study. The ankle brachial index (ABI) was collected using a portable vascular eco Doppler. Clinical and social- demographic information was collected using and structured evaluation form. Diabetes and arterial hypertension diagnosis were confirmed by clinical diagnosis and the use of medication for the disease. Data were collected at FACISA/UFRN. Results: 106 elderly were recruited for the study, 77,36% females and 22,64% males. Mean age was 68,1±5,08 years. When arterial obstruction was assessed it was found that 22,64% of the individuals showed ABI <0.9, being most of them from female gender. Most of the participants were white being 64,15% of the total sample. The highest prevalence was found on black people with 25%. When risk factors were assessed we found that 27,58% and 31,03% of the subjects with diabetes and arterial hypertension diagnosis, respectively, showed ABI < 0.9. Conclusion: among the sample 21,76% showed ABI < 0.9 indicating the presence of peripheral arterial occlusion. Intrinsic risk factors found in the study were female gender and black skin. Besides that, individuals with diabetes and hypertension showed higher prevalence of occlusion compared to healthy individuals. Thus, assessed risk factors may have direct inference in the disease prevalence and ABI showed to be efficient on assessing the presence of PAOD.
