Koroner arter hastalıklarının tanısında dobutamin stres radyonüklid ventrikülografi

Bu çalışmada dobutamin stres radyonüklid ventrikülo grafinin (RNV) koroner arter hastalıkları (KAH) tanısındaki değeri araştırıldı. Çalışmaya koroner arter hastalığı şüphesi olan toplam 48 hasta dahil edildi. Bu hastaların yapılan anjiografilerinde 26 tanesinde KAH tespit edildi ve bunların 24'ü erkek, 2'si kadın olmak üzere yaş ortalaması 53.5±13.3 idi. Koroner arter hastalığı olmayan 22 hastanın ise 3'ü kadın, 19'u erkek ve yaş ortalaması 44.4±11.0 idi (p

Dobutamine stress radionuclide ventriculography for the detection of coronary artery disease

The value of dobutamine stress radionuclide ventriculography in the diagnosis of coronary artery disease (CAD) was investigated in this study. Forty-eight patients with suspected CAD were included in this study. Twenty-six (24 males, 2 females, mean age: 53.5±13.3 years) had angiographically proven CAD. The remaining 22 cases(19 males, 3 females) without CAD had a mean age of 44.4±11.0 years. Twenty minutes after the injection of 2 mg stannous pyrophosphate, 20 mCi Tc-99m-pertechnetate was administered i.v. and basal radionüklid ventrikülography (RNV) study was performed on left anterior oblique position. Then, dobutamine infusion was carried out at each 10 µgr/kg/min dose increment from 10 to a maximum of 40 µgr/kg/min throughout 10 minutes. RNV images were taken at the last 5 minutes of each dobutamine infusion. In patient with CAD, ejection fraction (EF) after dobutamine infusion was increased by 4.6 % of the basal value, whereas this value was 18.6% in patients without CAD (p
