RESUMEN
La seguridad para determinar el índice tobillo-brazo con método Doppler o con un aparato automático convencional de medir la presión arterial no está bien establecida cuando realizan la determinación médicos con poca experiencia. Para evaluar la eficacia diagnóstica de cada método en este grupo profesional, calculamos mediante angiografía la sensibilidad, la especificidad y los valores predictivos positivo y negativo en 158 piernas de 85 pacientes con síntomas de claudicación intermitente. Del total de piernas analizadas, 131 (83%) presentaron obstrucción significativa. El método oscilométrico mostró sensibilidad del 97%, especificidad del 89%, valor predictivo positivo del 98% y valor predictivo negativo del 86%. El método Doppler mostró sensibilidad del 95%, especificidad del 56%, valor predictivo positivo del 91% y valor predictivo negativo del 68%. Los resultados indican que el equipo automático de presión arterial tiene mejor rentabilidad diagnóstica cuando realizan la prueba médicos no especialmente entrenados en el manejo de la sonda Doppler (AU)
ABSTRACT
Relatively little is known on how the Doppler method compares with oscillometric measurement using a conventional automatic blood pressure device to determine the ankle-brachial index, when determinations are performed by physicians with little experience. To assess the diagnostic efficacy of both methods in this professional group, we calculated their sensitivity, specificity, and positive and negative predictive value in 158 legs of 85 patients with symptoms of intermittent claudication. Angiography was used as the gold standard. Of the legs examined, 131 showed significant arterial obstruction. The oscillometric method showed 97% sensitivity, 89% specificity, 98% positive predictive value, and 86% negative predictive value. The Doppler method showed 95% sensitivity, 56% specificity, 91% positive predictive value, and 68% negative predictive value. This study suggests that the automatic blood pressure equipment has greater diagnostic accuracy when the test is performed by physicians not specifically trained to use the Doppler probe (AU)
