Effect of High-Dose Statin Pretreatment on the Incidence of Periprocedural Myocardial Infarction in Patients Undergoing Percutaneous Coronary Intervention: Grading the Evidence Through a Cumulative Meta-analysis

Clin Cardiol. 2015 Nov;38(11):668-78. doi: 10.1002/clc.22471. Epub 2015 Oct 7.


Background: Previous studies have showed that high-dose statin pretreatment could reduce the incidence of periprocedural myocardial infarction (PMI) in patients undergoing percutaneous coronary intervention (PCI). However, previous analyses have not performed reliable grading of evidence.

Hypothesis: In previous analyses, it supposed that the high-dose statin pretreatment was effective in reduction of the rate of PMI. In this analysis, we evaluated the effect of high-dose statin pretreatment on the reduction of rate of PMI based on a cumulative meta-analysis and grading of evidence.

Methods: We assembled the relevant published randomized controlled trials that compared the efficacy of high-dose statin pretreatment prior to PCI. We evaluated the risk of PMI by a cumulative meta-analysis, with subgroups stratified by clinical classifications and different statin histories, and we conducted explicit grading of evidence.

Results: High-dose statin pretreatment caused a 55% reduction in PMI through this cumulative meta-analysis of 23 RCTs (odds ratio [OR]: 0.45, 95% confidence interval [CI]: 0.37-0.54). The effect of high-dose statin pretreatment was significant for the stable angina subgroup (OR: 0.42, 95% CI: 0.32-0.56), ACS subgroup (OR: 0.43, 95% CI: 0.29-0.64), and the mixed presentation subgroup (OR: 0.50, 95% CI: 0.36-0.70). In different statin therapy histories, high-dose statin pretreatment reduced incidence of PMI 55% in the statin-naive subgroup (OR: 0.45, 95% CI: 0.36-0.56) and 54% in the low-dose statin subgroup (OR: 0.46, 95% CI: 0.32-0.66). The GRADE system indicated that the overall evidence quality was moderate. This finding may strengthen the confidence in any recommendations.

Conclusions: High-dose statin pretreatment can reduce the rate of PMI, irrespective of either the clinical presentation or previous statin-treatment history. Importantly, the overall GRADE evidence quality was moderate.
