Abstract

Objectives: To conduct a systematic review and meta-analysis of studies examining the impact of periprocedural intravenous morphine on clinical outcomes in patients undergoing primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI). Background: Morphine analgesia may reduce the absorption of co-prescribed P2Y12 antagonists attenuating platelet inhibition. The impact of periprocedural intravenous morphine on clinical outcomes in patients undergoing PCI for STEMI is not well defined. Methods: Analysis of the electronic databases of MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, Web of Science and ClinicalTrials.gov for association of peri-PCI intravenous morphine use with in-hospital or 30-day myocardial infarction (MI) (primary outcome) and in-hospital or 30-day mortality. Results: A total of 11 studies were included for systematic review. One study was a randomized controlled trial, 10 were observational studies. Five studies including 3,748 patients were included in meta-analysis of in-hospital or 30-day MI. Within this group, patients were treated concurrently with ticagrelor (n = 2,239), clopidogrel (n = 1,256) and prasugrel (n = 253). There was no significant association of in-hospital or 30-day MI with intravenous morphine (odds ratio 1.88; 95% confidence interval [CI] 0.87–4.09; I2 0%). Across seven studies and 5,800 patients, no increased risk of mortality at the same composite time endpoint was evident (odds ratio 0.70; 95% CI 0.40–1.23; I2 19%). Conclusions: Periprocedural intravenous morphine administration was not associated with adverse short-term clinical outcomes in patients undergoing primary PCI for STEMI. Further randomized trial data are needed to evaluate the pharmacologic interaction between morphine and P2Y12 antagonists with clinical outcomes.
