Associação do índice tornozelo-braquial e claudicação intermitente em portadores de doença pulmonar obstrutiva crônica.

Abstract

Background: Chronic Obstructive Pulmonary Disease (COPD) is characterized by progressive airflow limitation resulting from abnormal inflammatory response to inhaled harmful particles and severe systemic dysfunction. COPD patients have a high prevalence of cardiovascular disease and claudication can be indicator symptom of peripheral arterial disease (PAD). The Ankle-Brachial Index (ABI) it is useful method for detecting changes in peripheral blood flow. Objective: To evaluate the association between PAD and intermittent claudication in patients with COPD. Methodo: correlational study evaluating COPD patients with stage II to IV (GOLD) of both sex. Claudication evaluated by questionnaire of Edimburgo and the ABI was measured in arms and legs through sphygmomanometer and portable Doppler vascular. Results: Sample (n = 51) aged 63.08 ± 6.9 years and body mass index 26.5 ± 6.5 kg / m². There was a prevalence of 33,3% of patients with PAD (n = 17, 04 claudication), 29,4% classified as borderline (n = 15, 6 being lame) and 37.3% normal for the presence of peripheral vascular disease (n = 19, 06 claudicant). 41.2% (n = 21) reported pain or discomfort in the legs and 31.4% (n = 16) reported claudication, of which 08 with Grade 1 and 08 with Grade 2. There was no correlation between borderline ABI and PAD ( r = 0,177e p = 0.332) and the occurrence of intermittent claudication. Conclusion: Detected prevalence of 62,7% of peripheral artery disease or predisposition to it in patients with COPD evaluated, and there was not, however, an association between the ABI and the occurrence of claudication.
