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).
