Abstract

Lower extremity arterial disease is a condition with varying frequency in different populations. Accurate diagnosis of lower extremity arterial disease with noninvasive means is an important clinical issue. Ankle brachial index is regarded as the most sensitive tool in the detection of this disease. This study aimed to examine the sensitivity and specificity of Edinburgh claudication questionnaire in detecting lower extremity arterial disease diagnosed by the ankle brachial index test in a group of Turkish adults. Subjects aged 50 years or older (n=200) were first filled the Edinburgh claudication questionnaire to assess leg symptoms and underwent ankle brachial index measurement at the same visit. Edinburgh claudication questionnaire detected claudication in 27 (13.5%) individuals and a low ankle brachial index was found in 19 (9.5%) subjects. Edinburgh claudication questionnaire did not sufficiently identify those peripheral artery disease cases diagnosed by ankle brachial index (sensitivity: 31.6%, specificity: 88.4%, positive and negative predictive values: 22.2% and 92.5%, respectively). Low sensitivity but high specificity and negative predictive values of Edinburgh claudication questionnaire in this Turkish sample suggested that this test as a screening tool only in asymptomatic subjects to confirm the absence of lower extremity arterial disease without measuring ankle brachial index.

Özet

Alt ekstremite arteriyel hastalığı toplumlara göre değişen sıklıklarda karşılaşılan bir durumdur. Alt ekstremite arteriyel hastalığının non-invaziv yöntemlerle doğru bir şekilde tanısının konulabilmesi önemli bir klinik sorundur. Ayak bileği kol basınç indeksi ölçümü bu hastalığın tanısında bilinen en duyarlı tanı aracıdır. Bu çalışmanın amacı ayak bileği kol basınç indeksi ile alt ekstremite arteriyel hastalığı tanısı konulmuş erişkin bir Türk toplumunda, Edinburgh Klodikasyon Anketi'nin hastalığı saptamadaki duyarlılık ve özgüllüğün belirlenmesidir. Çalışmaya 50 yaş ve üzerindeki 200 olgu dahil edildi. Katılımcılara Edinburgh klodikasyon anketi uygulandıktan sonra aynı vizitte ayak bileği kol basınç indeksi ölçümü yapıldı. Anket sonucunda 27 (%13,5) katılımcıda klodikasyon saptanırken 19 (%9,5) katılımcıda ayak bileği kol basınç indeksi düşük saptandı. Ayak bileği kol basınç indeksi ile tanı konulan periferik arter hastalarını saptamada Edinburgh klodikasyon anketi yetersiz kaldı (Duyarlılık %31,6; Özgüllük%88,4; pozitif ve negatif prediktif değerler %22,2 ve %92,5). Edinburgh klodikasyon anketinin düşük duyarlılığa rağmen, yüksek özgüllük ve yüksek negatif prediktif değere sahip olması, bu anketin sadece asemptomatik olgularda, ayak bileği kol basınç indeksi ölçümü yapmadan alt ekstremite arteriyel hastalığı olmadığının tespit edilmesinde tarama testi olarak kullanılabileceğini gösterdi.
