Quartile ranges: Q1 <11.84; Q2 11.84 to 38.30; Q3 38.30 to 100.35; Q4 >100.35 pg/ml. BNP = B-type natriuretic peptide.

Adjustment was performed in four consecutive models as outlined. The traditional risk factors (RFs) (models 2 to 4) comprised age, gender, a history of hypertension, diabetes, smoking status, body mass index, and high-density lipoprotein (the last two parameters entered the model as continuous variables). Presence of multivessel disease and therapy with angiotensin-converting enzyme inhibitors and statins entered the Cox regression analysis as clinical variables (models 2 to 4). BNP = B-type natriuretic peptide; CRP = C-reactive protein; EF = angiographically determined left ventricular ejection fraction.

View larger version (16K): [in a new window]   Figure 3 Hazard ratio associated with an increase of one standard deviation in the outlined variables. Model 1 is adjusted for age and gender. Model 2 additionally includes traditional risk factors (a history of hypertension, diabetes, smoking status, body mass index, and high density lipoprotein as continuous parameter) and clinical variables (multivessel disease and therapy with angiotensin-converting-enzyme inhibitors and statins). In addition, the adjusted areas under the receiver operating characteristics curve (AUC) are provided for the four variables assessed in the Cox regression model. It has to be noted that the final model included only 767 patients because of missing data for ejection fraction and C-reactive protein. Abbreviations as in Figure 2.
