Although peripheral arterial disease (PA) is an important clinical marker of cardiovascular morbimortality, the rate of under-diagnosis is unknown. Our aimed to know the proportion of patients underdiagnosed of PA and the associated factors.3786 patients49 years old, randomly selected, were studied. PA was diagnosed by means of the ankle-brachial index (ABI0, 9). Underdiagnosed was considered when ABI0, 9 and when they were not diagnosed of PA in the clinical record. We also determined the presence of intermittent claudication (IC) defined by Edinburgh's questionnaire.7,6% had an ABI0, 9 (IC95% 6.7-8.4). Of these patients 80.7%, were underdiagnosed, although the 29.3% had IC. PA underdiagnosis was low in current smokers or former smokers (OR 0.20; IC95% 0.07-0.59), if IC (OR 0.40; IC95% 0.18-0.89), if ABI between0.7 and 0.5 (OR 0.36; IC95% 0.16-0.81) or0,5 (OR 0.04; IC95 % 0.01-0.20), being higher in70 years (OR 3.12; IC95% 1.12-8.67).PA underdiagnosis is high, especially in old patients. It is necessary to reach consensus criteria for the practice of the ABI in the general population. |
