Efficacy and safety of new oral anticoagulants combined with antiplatelet drugs in the treatment of coronary heart disease: Systematic evaluation and meta‐analysis

Objective To analyze the efficacy and safety of antiplatelet drugs combined with new oral anticoagulants (noac) in the treatment of coronary atherosclerotic heart disease (CAD). Methods The randomized controlled trials of noac combined with antiplatelet therapy in Cochrane, CNKI, PubMed, EMBASE, Wanfang, Google Scholar, and Baidu library were searched using the literature database. Two researchers independently searched and screened to ensure the consistency of the results, and the literature was summarized and analyzed by Revman 5.3 software. Results Five research results were included. The results showed that the incidence of mace [95% CI 0.75-0.95, or = 0.84,p = .04], the incidence of major and minor bleeding [95% CI 1.25-5.16, or = 2.54,p = .01], the mortality of cardiovascular disease [95% CI 0.78-0.96, or = 0.86, p = .05], the total mortality [95% CI 0.79-0.95, or = 0.87, p = .003], and the incidence of myocardial infarction in patients with CAD treated with noac and antiplatelet drugs [95% CI 0.77-0.95, or = 0.85, p = .004] was lower than that treated with antiplatelet drugs alone, and the difference was statistically significant (p < .05); the incidence of fatal bleeding [95% CI 0.81-2.08, or = 1.30, p = .28], the incidence of stroke [95% CI 0.50-1.03, or = 0.71, p = .07], and the incidence of intracranial hemorrhage [95% CI 1.02-2.56, or = 1.61, p = .06]. There was no significant difference with antiplatelet drugs alone (p > .05). Conclusion Noac combined with antiplatelet drugs can reduce mace, total mortality, the incidence of myocardial infarction, and cardiovascular mortality in patients with CAD, but may increase the risk of bleeding.
