Abstract

BACKGROUND
To assess the valve of stress scintigraphy in patients with left bundle branch block(LBBB), patients with LBBB underwent stress scintigraphy, coronary angiography and left ventriculography. METHOD: Exercise(n=12) or pharmacology(n=1) scintigraphy, coronary angiography and left ventriculography were performed in 13 patients(12 men and 1 woman, aged 53-81 years) with LBBB. RESULT: 1) All patients had anteroseptal defects on scintigram. 2) Among these, 3 patients(23%) did not have any significant coronary artery stenosis on coronary angiogram. CONCLUSION: Stress scintigraphic change may not help much in the detection of coronary artery disease(CAD) in patients with LBBB.
