However, there is uncertainty regarding its usefulness in reducing major adverse cardiovascular events in stable chest pain patients. Methods: We have searched EMBASE, PubMed, and Cochrane Library (inception through May 24th, 2022) for randomized controlled trials (RCTs) evaluating CCTA versus ICA in stable chest pain. The Mantel-Haenszel method was used with Paule-Mandel estimator of tau2 and Hartung-Knapp-Sidik-Jonkman adjustment (given small number of the included studies) to calculate the risk ratio (RR) and 95% confidence interval (CI). Results: Three RCTs with a total of 5,393 patients were included in this study. There was no significant difference between CCTA and ICA in terms of myocardial infarction [RR: 1.12; 95%CI: 0.60; 2.09; I2:0%] [Figure ], stroke [RR: 0.52; 95%CI: 0.22; 1.24; I2:0%], all-cause mortality [RR: 1.83; 95%CI: 0.17; 20.18; I2:50%], or cardiovascular mortality [RR: 0.47; 95%CI: 0.02; 9.15; I2:0%]. Conclusion: This meta-analysis suggests that there is no difference between CCTA and ICA for stable chest pain evaluation in terms of myocardial infarction, stroke, all-cause mortality, or cardiovascular mortality.
