Meta AnalysisThe role of statins in the prevention of contrast induced nephropathy: a meta-analysis of 8 randomized trials.
Contrast induced nephropathy (CIN) is a common complication of coronary angiography/angioplasty. Prevention is the key to reduce the incidence of CIN and it begins with appropriate pre-procedural management. Statins have been shown to possess pleiotropic effects (anti-oxidant, anti-inflammatory and anti-thrombotic properties) and their effects on CIN were assessed in several studies with conflicting results. ⋯ Benefits were both observed with high-dose short-term statins [OR 95% CI 0.44 (0.30-0.65), p < 0.0001; p het = 0.16] and low-dose statins, [OR 95% CI 0.58 (0.39-0.88), p = 0.010; p het = 0.90]. By meta-regression analysis, no significant relationship was observed between benefits from statin therapy and patient's risk profile (p = 0.26), LDL cholesterol (p = 0.4), contrast volume (p = 0.94) or diabetes rate (p = 0.38). This meta-analysis showed that among patients undergoing coronary angiography/percutaneous intervention the use of short-term statins reduces the incidence of CIN, and therefore is highly recommended even in patients with low LDL-cholesterol levels.
