Abstract:Objective To evaluate the impact of antidepressant drugs (SSRIs) on the efficacy and inflammatory factors in patients with coronary heart disease (CHD) with depression, and to provide modern pharmacological basis for antidepressant drugs in the treatment of CHD with depression.. Methods Data of China National Knowledge Infrastructure, Wanfang database, VIP database, PubMed, and the Cochrane Library database on randomized controlled trials about antidepressant drugs in the treatment of CHD with depression from the establishment of the database to December 2019 was researched, and the results that met the quality standards were analyzed with meta-analysis. RevMan5.3 software was used to perform the meta-analysis. Results A total of 1124 patients were included in 12 studies. Compared with the control group, meta-analysis showed that C-reactive protein [SMD = -0.85, (95% CI: -1.32, -0.37)], interleukin-6 [SMD = -1.22, (95% CI: -1.49, -0.95)], interleukin-8 [SMD = - 1.17, (95% CI: -1.48, -0.87)], and tumor necrosis factor-alpha [SMD = -2.04, (95% CI: -2.32, -1.75)] were decreased in the antidepressant drugs group. The treatment of antidepressant drugs group was superior to the control group [RR = 1.23, (95% CI: 1.01, 1.51)], the recurrence rate of myocardial infarction in the antidepressant group was lower than the control group [RR = 0.3, (95% CI: 0.12, 0.74)], and the score of depression scale was lower than that of the control group [SDS scale: SMD = -2.04, (95% CI: -2.87, -1.20); HAMD scale: SMD= -4.73, 95% CI: (-6.23, -3.23)], and the differences were statistically significant. Conclusions According to the existing literature, SSRIs antidepressant drugs do have certain effect on treating CHD with depression and effectively reduce the levels of CRP, IL-6, IL-8, and TNF-α.
