Effect of statins therapy prior to percutaneous coronary intervention.
Many previous studies have demonstrated that statins pre-treatment before percutaneous coronary intervention (PCI) reduced myocardial infarction (MI) in statin-naive patients with both stable angina and acute coronary syndrome. However, clinical benefit of statins is controversial as some studies have shown different results. A search of MEDLINE, EMBASE using the term statins AND PCI, statins AND percutaneous coronary intervention. The review was limited to articles published in English between January 1990 and July 2011. Most trials noted that statins pretreatment before PCI in patients are associated with risk reduction of periprocedural myocardial infarction (PMI) and major adverse cardiovascular events (MACE). The mechanisms underlying this protective action of statins possibly attribute to the pleiotropic effects. However, controversial results were also reported in some trials that early use of statins before PCI did not influence occurrence of PMI or long-term clinical outcomes. Statins therapy among PCI patients seems to be associated with a significant mortality advantage at early and long-term follow-up. However, currently early statins use before intervention still cannot serve as a routine strategy of treatment. Further large-scale randomized studies are critically required to demonstrate the importance of early treatment with statins in pre-PCI.
