Abstract:
OBJECTIVETo investigate the predictive value of elevated fibrinogen and high-sensitivity C-reaction protein (hs-CRP) level on cardiovascular events in patients with stable coronary artery disease (CAD).
METHODSFrom January 2002 to November 2002, 185 patients (aged 47 - 85 years) with stable CAD referred for coronary angiography were enrolled and divided into control-F (fibrinogen level < or = 4.0 g/L, n = 104) and elevated-F (fibrinogen level > 4.0 g/L, n = 81), or control-hs (hs-CRP < or = 3.0 mg/L, n = 99) and elevated-hs (hs-CRP> 3.0 mg/L, n = 86). Exclusion criteria included cardiomyopathy, New York Heart Association class IV congestive heart failure, recent myocardial infarction or coronary artery revascularization and cancer. During three years follow-up, cardiovascular death, myocardial infarction, congestive heart failure, stroke and other vascular events were assessed.
RESULTSA total of 21 cardiovascular nonfatal events and 10 cardiovascular deaths were observed. Cardiovascular events was significantly higher in patients in elevated-F group than that in control-F group [23.46% vs. 11.54%, cholesterol-, body mass index-, smoking-, and hypertension-adjusted relative risk 1.97, 95% CI (1.68 to 2.40), P < 0.05] and in elevated-hs group than in control-hs group [24.42% vs. 10.10%, adjusted relative risk 2.32, 95% CI (1.76 to 2.89), P < 0.05]. The relative risk of cardiovascular events for patients with fibrinogen > 4.0 g/L and hs-CRP > 3.0 mg/L was 3.84 (P < 0.05), 95% CI (2.80 to 4.99) compared with patients with fibrinogen < or = 4.0 g/L and hs-CRP < or = 3.0 mg/L.
CONCLUSIONBoth fibrinogen and hs-CRP are independent important predictors of cardiovascular nonfatal and fatal events in patients with stable CAD. Combination of elevated fibrinogen and hs-CRP increased their predictive value for cardiac events.
