Abstract |
As the indication of percutaneous coronary intervention (PCI) has expanded to the more difficult and complicated
cases, frequent restenosis is still expected after PCI. According to AHA/ACC guideline of the present time, routine
use of myocardial perfusion single photon emission tomography (SPECT) is not recommended after coronary
intervention, but symptom itself or exercise EKG is not enough for the detection of restensis or for the prediction
of event-free survival. In high risk and/or symptomatic subjects, direct coronary angiography is required.
Myocardial perfusion SPECT could detect restenosis in 79% of the patients if performed 2 to 9 months after PCI.
Reversible perfusion decrease in the myocardial perfusion SPECT is known to be the major prognostic indicator of
major adverse cardiac event in PCI patients and also the prognosis is benign in the patients without reversible
perfusion decrease. Though the cumulated specificity is 79% in the literature and optimal timing of myocardial
perfusion SPECT is in controversy, SPECT is recommended even in asymptomatic patients at 3 to 9 months after
PCI. Considering the evidences recently reported in the literature, myocardial perfusion SPECT is useful for risk
stratification and detection of coronary artery restenosis requiring re-intervention in the asymptomatic patients
after PCI.(Korean J Nucl Med 39(2):114-117, 2005) |
