Tc-99m-MIBI in Patients with Obstructive Coronary Artery Disease: Correlation between Quantitative Coronary Angiography and

To correlate myocardial perfusion scintigraphy (MPS) with Tc-99m-MIBI and adenosine infusion using quantitative coronary angiography (QCA) and intravascular ultrasound (IVUS). METHODS Seventy patients with coronary artery disease (CAD) referred for myocardial perfusion scintigraphy (MPS) with MIBI and adenosine were studied. Clinical, electrocardiographic (ECG), and scintigraphic fi ndings were correlated with variables of visual and quantitative angiographic analysis, as well as to those of IVUS. RESULTS The mean age of patients was 60.6 years, and 39 were male. Coronary angiography showed percentage of diameter stenosis ( % DS) of 49.94 % in 105 arteries
