title: Relation of markers of inflammation (C-reactive protein, fibrinogen, von Willebrand factor, and leukocyte count) and statin therapy to long-term mortality in patients with angiographically proven coronary artery disease.
abstract: We evaluated a possible interaction between statins and inflammation in 1,246 patients with angiographically diagnosed coronary artery disease. Four different inflammatory markers were determined: high, sensitive C-reactive protein (hs-CRP) (p = 0.001), fibrinogen (p = 0.006), von Willebrand factor (p = 0.006), and leukocyte count (p = 0.03); these levels were significantly higher among the 88 patients who died of cardiac causes during follow-up (median 2.9 years) than among survivors. In a multivariate backward stepwise Cox regression mode, only hs-CRP was evaluated to be a significant predictor of death from coronary artery disease. This prediction was lost in statin-treated patients. Compared with patients receiving statin medication, patients without statins did not have increased cardiac mortality (even when low-density lipoprotein [LDL] levels were >125 mg/dl) when hs-CRP levels were not elevated. In contrast, patients without statins and elevated hs-CRP (top quartile) had a 2.3-fold increase in risk for fatal coronary events, independent of LDL levels. In conclusion, only elevated hs-CRP was selected as an independent predictor of death. Statin therapy is associated with elevated hs-CRP, with a risk reduction for fatal coronary events, independent of LDL levels; this, in part, may be explained by the anti-inflammatory effects on atherosclerosis.
