NO
To investigate whether a washout rate (WR) obtained from myocardial scintigrams predicts severity of myocardial infarction and prognosis after percutaneous coronary intervention (PCI). The effect of cardiac rehabilitation on WR was also assessed.

2.Myocardial planner images
Planner images obtained in the early and delayed phase after tracer injection
3.Myocardial single photon emission computed tomography (SPECT)
Short-axis SPECT images at rest
4.Gated SPECT
Left ventricular (LV) end systolic and diastolic volumes, LV ejection fraction, LV diastolic function
1.Planner images in the lower
extremities (using 99mTc-MIBI)
Images in the upper and lower thighs obtained at the early phase after tracer injection
2.Cardiopulmonary exercise testing
Systolic and diastolic blood pressures at rest, at warming up, during exercise, at peak exercise and cooling down, pulse, a respiratory rates (RR), minute ventilation (VE), oxygen uptake (VO2), a carbon dioxide production rate (VCO2), the relation between ventilation and VO2 (VE/ VO2), the relation between ventilation and VCO2 (VE/VCO2), anaerobic threshold (AT), peak VO2, VE/VCO2 slope, VO2/WR, end-tidal oxygen tension pressure (PETO2), end-tidal carbon dioxide pressure (PETCO2)

Not applicable |
Male and Female
Patients with acute myocardial infarction confirmed by coronary angiography and those who were successfully treated with PCI in the acute phase were enrolled.
Patients who had acute coronary syndrome within the last half year, those with severe hepatic and/or renal impairment, those with inappropriate arrhythmia, such as premature ventricular contraction (PVC) and atrial fibrillation, for electrocardiography-gated SPECT data collection, and small heart patients.

Evaluation:
Nowadays, serum CK, CK-MB, and serum troponin are used to predict severity and prognosis in patients with acute myocardial infarction. BNP is also known as a reliable indicator of heart failure; however, BNP is not an independent prognostic indicator for severity of acute myocardial infarction. BNP levels correspond to severity of injuring in infarct area and LV diastolic function; BNP together with LVEF is useful to predict prognosis after the onset of acute myocardial infarction. Meanwhile, WR, which is obtained at the early and delayed phase after 99mTc-MIBI injection, correlates with severity of heart failure and impaired myocardium. It has been reported that WR obtained from 123I-BMIPP scintigrams has the similar results. Accordingly, WR obtained from 99mTc-MIBI scintigrams may become a predictor of severity and prognosis after treatment in acute myocardial infarction patients.
