Treadmill egzersiz elektrokardiyografi testinde izole inferior bölge ST çökmeleri saptanan hastalarda dobutamin stres ekokardiyografi testi ile iskeminin değerlendirilmesi
Abstract
Treadmill egzersiz stres testinde (TMET) izole inferior ST segment depresyonu olan hastalarda, koroner iskemiyi tanımada dobutamin stres ekokardiyografi testinin (DSET) uygunluğu ile duyarlılık, özgüllük, pozitif ve negatif öngörü değerlerini araștırmayı amacladık.YÖNTEMÇalıșmaya, TMET’de inferior bölgede, ST segmentinin J noktasından 80 ms sonra ≥1 mm down sloping veya horizontal çökmeleri olan, 70 erkek hasta alındı. Bütün hastalara yaşa özgü maksimal kalp hızının en az %85’ine ulaşana kadar DSET uygulandı. DSET sonrası 15±5 gün içinde, koroner dolaşımı değerlendirmek için altın standart test olarak selektif koroner anjiyografi ve ventrikulografi yapıldı.BULGULARHastaların ortalama yaşları 52±9’du. Koroner anjiyografide 28 hastada vasküler stenoz ( bir damarda ≥ %50) belirlendi. DSET bunların 23’ünde pozitif ve 5’inde negatifti. DSET pozitif hastalar 16 tek damar ve 7 iki damar hastalığından oluşuyordu. Koroner anjiyografi 42 hastada normaldi (stenoz yoktu ya da %50’den azdı). Bu hastaların 39’unda DSET negatifti. Ancak, vasküler stenozu olmayan (
Assessment of ischemia by using dobutamine stress echocardiography test in patients with isolated ST depression in inferior leads demonstrated during channel treadmill exercise electrocardiography test
Abstract
AIMWe aimed to evaluate the diagnostic sensitivity, specificity, positive and negative predictive value of dobutamine stress echocardiography test (DSET) in the diagnosis of cardiac ischemia in patients with isolated inferior ST segment depressions in treadmill exercise stress test (TMET).METHODSSeventy male patients with horizontal or down sloping of ≥1 mm ST segment depressions, 80 msc after J point in inferior leads during TMET were included in the study. DSET was applied to all patients until at least an 85% of age specific maximal heart rate was reached. A selective coronary ventriculographic examination as a gold standard to evaluate the coronary circulation was performed within 15±5 days of the DSET.RESULTSThe mean age of the patients was 52±9 years. Vascular stenosis (≥ 50% of a vessel) was demonstrated in the angiographic examination of 28 patients. DSET was positive in 23 and negative in 5 of these cases. DSET positive patients consist of 16 single vessel and 7 two vessel diseases. Coronary angiography examination was normal in 42 of the patients (without stenosis or stenosis of
