A Systematic Review
Objective: To evaluate the current prophylactic strategies against CIN in patients with STEMI treated by primary percutaneous coronary intervention. Background: Contrast-induced nephropathy (CIN) is the third leading course of acute renal failure and a recognized complication to cardiac catheterization. CIN is associated with increased risk of cardiac adverse events and mortality, and recent studies point at the risk of developing a transient or persistent renal dysfunction. Patients with ST-elevation myocardial infarction treated by primary percutaneous coronary intervention have a markedly increased risk of developing CIN. At present no strategy is universally accepted in the prevention of CIN in the acute setting of primary percutaneous coronary intervention. Method: We performed a systematic search in Pubmed and EMBASE and ended up including nine randomised clinical trials; six studies of N-acetylcysteine, one study of early and late hydration regimens, one study of recombinant human brain natriuretic peptide and one study comparing a low-osmolar contrast agent with an iso-osmolar contrast agent. Results: Recombinant human brain natriuretic peptide and the regimens of hydration significantly reduced the incidence of CIN and administration of N-acetylcysteine in one of the six studies significantly reduced the occurrence of CIN. The iso-osmolar contrast agent was not proven to be superior to the low-osmolar contrast agent in terms of preventing CIN. Conclusion: Preliminary studies are promising but further studies are needed before any prevention strategy against CIN can be recommended in routine care of patients undergoing primary percutaneous coronary intervention for STEMI.
