Good adherence to evidence-based medications in stable coronary artery disease was associated with a lower risk of all-cause mortality (risk ratio 0.56; 95% CI 0.45-0.69).
Meta-Analysis (n=106,002)
Does good medication adherence reduce mortality and cardiovascular events in patients with stable coronary artery disease?
Good adherence to evidence-based medications in stable coronary artery disease is associated with significantly reduced risks of all-cause mortality, cardiovascular mortality, and cardiovascular hospitalization or myocardial infarction.
Effect estimate: risk ratio 0.56 (95% CI 0.45-0.69)
Background Long-term use of evidence-based medications is recommended by international guidelines for the management of stable coronary artery disease, however, non-adherence to medications is common. This meta-analysis aims to systematically evaluate the impact of medication adherence on clinical outcomes in patients with stable coronary artery disease. Methods Articles from January 1960-December 2015 were retrieved from the MEDLINE and EMBASE databases without any language restriction. A meta-analysis was performed to investigate the risk ratios of all-cause mortality, cardiovascular mortality, and myocardial infarction/hospitalization between groups with good medication adherence and poor medication adherence. Studies were independently reviewed by two investigators. Data from eligible studies were extracted, and the meta-analysis was performed using R Version 3.1.0 software. Results A total of 10 studies were included in the analysis, with a total of 106,002 coronary artery disease patients. The results showed that good adherence to evidence-based medication regimens, including β-blockers, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, antiplatelet drugs, and statins, was related to a lower risk of all-cause mortality(risk ratio 0.56; 95% confidence interval: 0.45-0.69), cardiovascular mortality(risk ratio 0.66; 95% confidence interval: 0.51-0.87), and cardiovascular hospitalization/myocardial infarction(risk ratio 0.61; 95% confidence interval: 0.45-0.82). Conclusions This meta-analysis confirms the significant impact of good medication adherence on clinical outcomes in patients with stable coronary artery disease. More strategy and planning are needed to improve medication adherence.
Du et al. (Fri,) conducted a meta-analysis in stable coronary artery disease (n=106,002). Good medication adherence vs. Poor medication adherence was evaluated on all-cause mortality (risk ratio 0.56, 95% CI 0.45-0.69). Good adherence to evidence-based medications in stable coronary artery disease was associated with a lower risk of all-cause mortality (risk ratio 0.56; 95% CI 0.45-0.69).
