Cardiovascular event risk estimated by myocardial perfusion SPECT combined with clinical data

Myocardial scintigraphy plays important roles in the diagnosis of coronary artery disease, prognostic risk stratification, and determination of the treatment policy. Recently, several large-scale clinical trials reported that coronary intervention was not necessarily advantageous for preventing future cardiac events in patients with stable angina. This review summarizes how we can estimate cardiac event risks based on Japanese Assessment of Cardiac Events and Survival Study by Quantitative Gated SPECT (J-ACCESS), and describes that the combination of scintigraphy and other clinical features leads to more accurate stratification of prognosis and the determination of subsequent treatment policy.
