  Background: Rest-Redistribution thallium(R-RD Tl) imaging has high negative predictive value (NPV) but low positive predictive value (ppv) for the prediction of recovery of regional myocardial dysfunction after revascularization (Rev). Combining myocardial perfusion (MP) and functional data with nitrate-enhanced gated SPECT MIBI (GSM) at rest appears to be a promising approach for viability detection. Aim of the Study: Differentiate between clinical and academic viability. Methods: Total of 66 patients with CAD underwent R-RD Tl,2 sets of resting GSM using 2 MIBI injections, and echocardiography at rest andafter low dose dobutamine (LDD). One hour before GSM2, trimetazidine (TMZ) andnitrate, had been given. All pts had their echo repeated after (Rev) as a golden standard for clinical viability one year later. Myocardia.. Read More»
