To evaluate the prognosis in 57 patients with old myocardial infarctions, 201Tl myocardial scintigraphy and 99mTc-HSA gated blood pool scan had been done as a 5-year follow up study.
We subdivided into two groups; group I (over 60 years) and group II (under 60 years) . Cardiac index (CI) and right ventricular ejection fraction (RVEF) did not change significantly, however left ventricular ejection fraction (LVEF) changed significantly (p<0.05) .
Corelationship between CAG score and ΔLVEF by handgrip exercise test was y=-1.34x+3.61 (n=44, r=-0.400, p<0.01) . Otherwise, Tl defect ratio between first and final examination did not show the significant change in two groups. In conclusion, nuclear examination (cardiac function and myocardial blood flow) is significant to evaluate the prognosis in patients with myocardial infarction.
