Abstract Acute Myocardial infarction is a serious event that caries a significant morbidity and mortality (Grines et al, 1993). Risk stratification after AMI is one of the clinical application of MPI (Pollok et al, 1992). The combination of clinical and stress MPI provided greater prognostic information that did the combination of clinical and angiographic data alone (Palmas W et al, 1995). Several recent studies demonstrated that stress MPI retains its predictive value in AMI patients receiving thrombolysis (Heller GV et al,1997). Stress MPI is well able to risk stratification of patients after uncomplicated MI and can in many cases preclude the need for cardiac catheterization (Mahmarian JJ et al., 2004). It is now clear that patients with normal stress MPI have a benign prognosis with an event rate (death or nonfatal MI) of less than 1% per year. On the other hard, the risk increases in patients who have abnormal scans (Iskandrian As et al, 1993). |
