Abstract Acute STEMI is the most serious presentation of CAD carrying the most hazardous consequences and it is caused by occlusion of major coronary artery with primary goal in the management to start reperfusion therapy as early as possible. Tc99m-Sistamibi scan is the gold standard for assessing the size of infarction before and after reperfusion, despite the radiation hazard it poses. The aim of the work is to assess the ability of modified Selvester QRS score to predict myocardial salvage in patients with acute ST-elevation myocardial infarction after primary coronary intervention. This study was conducted on thirty patients presented to Ain Shams university hospital by acute STEMI eligible for reperfusion therapy within the period between September 2010 and July 2011. All patients underwent primary PCI after diagnostic coronary angiography; the IRA was identified and treated using bare metal stents ± pre-dilatation by balloons according to discretion of treating physician. Before primary PCI all patients were given an intravenous dose of Tc-99m labeled sestamibi (20-30 mCi) then, after primary intervention 1st SPECT image was taken within 6 hours from the time of injection of the radioactive material to assess the initial size of the perfusion defect prior to reperfusion (myocardium at risk). |
