[Diagnostic value of left ventricular function after adenosine loading detected by gated myocardial perfusion imaging for prediction of major adverse cardiac events].
This study was aimed to analyze the value of the SPECT MPI to myocardial ischemia and cardiac function parameters in the CAD prognosis assessment. A total of 890 patients with suspected CAD underwent adenosine loading stress gated SPECT. At a mean follow-up of (2.3 +/- 0. 4) year, a total of 37 adverse events occurred, including 12 cardiac deaths and 25 nonfatal myocardial infarctions. Univariate Cox analysis showed that diabetes (wald 6.95, P < 0.01), SSS (wald 24.31, P < 0.001), EF (wald 17.14, P < 0.001), ESV (wald 8.58, P < 0.01) and EDV (wald 7.95, P < 0.01) were significant predictors of MACEs. Multivariate Cox analysis showed that SSS (wald 6.69, P < 0.05) and EF (wald 4.70, P < 0.05) were independent predictors. According to the results, SSS and EF are both independent predictors of MACEs.
