ObjectiveTo investigate the efficacy of psychocardiology mode in the treatment of coronary heart disease complicated with insomnia using Meta-analysis. MethodPublished articles in Chinese and English meeting the inclusion and exclusion criteria of this study were retrieved from CNKI, VIP Database, Wanfang Database, China Biomedical Literature Database, PubMed, Embase, and the Cochrane Library from the database establishment to April 2022, and the RevMan 5.4.1 software was used for a Meta-analysis which aimed to evaluate the efficacy of psychocardiology mode in the treatment of coronary heart disease complicated with insomnia according to indexes of both insomnia and coronary heart disease. ResultsA total of 21 randomized controlled trials involving 2 272 patients were included, of which 12 articles were of relatively high quality. The Meta-analysis results showed that in terms of insomnia, the intervention group (psychocardiology mode treatment) had a lower Pittsburgh Sleep Quality Index (PSQI) score (MD=-3.55, 95% CI ［-4.17, -2.93］, P＜0.05), a higher excellent and good rate of sleep quality (OR=4.38, 95% CI［2.86, 6.72］, P＜0.05), and a higher effective rate in treating insomnia (OR=3.70, 95% CI［1.70, 8.05］, P＜0.05) than the control group; in terms of coronary heart disease, the intervention group had lower frequency of angina pectoris attack (MD=-3.47, 95% CI［-4.18, -2.76］, P＜0.05), shorter angina pectoris duration (MD=-3.07, 95% CI［-3.86, -2.27］, P＜0.05), and decreased cardiac troponin I level (MD=-0.13, 95% CI［-0.18, -0.09］, P＜0.05) and incidence of cardiovascular adverse events (OR=0.18, 95% CI［0.10, 0.33］, P＜0.05) than the control group. ConclusionPatients with coronary heart disease and insomnia who have received psychocardiology mode therapy have better improvements in both insomnia and coronary heart disease than those who have received conventional coronary heart disease treatment.
