Prognostic value of multislice computed tomography and gated single-photon emission computed tomography in patients with suspected coronary artery disease.

摘要: Objectives This study was designed to determine whether multislice computed tomography (MSCT) coronary angiography has incremental prognostic value over single-photon emission myocardial perfusion imaging (MPI) in patients with suspected artery disease (CAD). Background Although MSCT is used for the detection of CAD addition MPI, its unclear. Methods In 541 (59% male, age 59 ± 11 years) referred further cardiac evaluation, both and MPI were performed. The following events recorded: all-cause death, nonfatal infarction, unstable angina requiring revascularization. Results 517 (96%) an interpretable MSCT, significant (MSCT ≥50% stenosis) detected 158 (31%) patients, abnormal (summed stress score [SSS]: ≥4) observed 168 (33%) patients. During follow-up (median 672 days; 25th, 75th percentile: 420, 896), event occurred 23 (5.2%) After correction baseline characteristics a multivariate model, emerged as independent predictor MPI. annualized hard rate (all-cause mortality infarction) none or mild Conclusions provides Combined anatomical functional assessment may allow improved risk stratification.
