| Popis: | Background Given the complex etiology and a limited amount of evidence, the medical treatment (including statin use) of myocardial infarction with non-obstructive coronary artery disease (MINOCA) remains uncertain. The objective of the present study was to evaluate the effect of statin therapy on major cardiovascular events (MACE) and mortality in MINOCA patients. Methods A systematic review and meta-analysis of time-to-event outcomes were performed from statin's studies therapy on MINOCA patients, reporting data from MACE or mortality, after searching the PubMed/MEDLINE, Embase, Science Direct, Scopus, Google Scholar, and Cochrane databases. The Meta-analysis Of Observational Studies (MOOSE) and the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines were used to check the reporting of observational studies. The quality of the included studies was assessed by two independent review authors using the Newcastle-Ottawa Scale (NOS). The summary effect of statin therapy on the endpoints were calculated. Measures of effect size were expressed as HRs, and the I2 statistic was calculated to quantify between-studies heterogeneity and inconsistency. A fixed-effects meta-analysis model and sensitivity analysis was then applied. The level of statistical significance was set at a 2-tailed alpha of 0.05. Results Six observational studies of statin therapy on MINOCA, involving a total of 11171 patients, were identified and considered eligible for analysis (9129 subjects received statin therapy while 2042 patients were part of the respective control arms). Quantitative analysis (5 studies were included) showed that statin use was associated with lower mortality (HR: 0.65; 95% CI: 0.56–0.75, I2: 0%). Also, the meta-analysis showed that statin therapy was associated with a lower incidence of MACE (HR: 0.78; 95% CI: 0.69–0.88, I2: 27%). Conclusion Our data suggest that in a population with MINOCA, the use of statin therapy results in significant reduction on MACE and mortality. These results must be confirmed in future clinical trials. Funding Acknowledgement Type of funding sources: None. Mortality and MACESensitivity analysis |
