Abstract:
BACKGROUND:The effects of initial tests on long-term events have been unknown. PATIENTS AND METHODS:In this observational retrospective study, we analyzed the effects of initial noninvasive tests by myocardial perfusion imaging (MPI) and computed tomography angiography (CTA) on long-term major adverse cardiac events (MACEs) among patients with suspected coronary artery disease during a median follow-up of 8.1 years (interquartile range: 7.7-8.9). RESULTS:Sex difference in the rate of abnormal findings on initial tests was observed in both the MPI (female vs. male: 32.6 vs. 55.5%; P<0.0001) and CTA groups (30.6 vs. 47.9%; P<0.0001). Early revascularization in the MPI was significantly lower than that in the CTA (16 vs. 23%; P=0.0005). A total of 109 MACEs (39 of 1830 patients during the original follow-up period and 70 of 616 patients during the extended follow-up period) occurred: 77 MACEs (6.4%) in the MPI group and 32 (5.1%) in the CTA group (adjusted hazard ratio for MPI: 0.78; 95% confidence interval: 0.50-1.23; P=0.29). In the total cohort, the risk-adjusted MACE rate in the females was ∼50% of the males. CONCLUSION:The long-term MACE rates did not differ between physician-referred initial tests of MPI and CTA despite a higher frequency of early revascularization in the CTA group. In this extended cohort, female sex was associated with a lower rate of positive findings and a lower MACE rate compared with the male sex.
