Abstract

Background - Patients with chronic stable angina are poorly characterized in terms of biomarkers that help in the assessment of prognosis. We investigated whether plasma levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) may be used as a prognostic marker in patients with chronic stable angina treated with coronary stenting. Methods and Results - Plasma levels of NT-proBNP were measured in 1059 patients with chronic stable angina and coronary angiographic confirmation of significant coronary artery disease. The primary end point of the study was mortality. After a median of 3.6 years (interquartile range, 3.3 to 4.5 years), there were 106 deaths. Kaplan-Meier estimates of 5-year mortality were 4.7% in the first quartile, 7.8% in the second quartile, 11.4% in the third quartile, and 32.7% in the fourth quartile of NT-proBNP (P<0.001). A Cox proportional hazards model showed that NT-proBNP was the strongest correlate of mortality (adjusted hazards ratio [HR], 5.83 [95% confidence interval: 2.07 to 16.44] for the fourth versus the first quartile). A similar prognostic value of NT-proBNP was demonstrated for cardiovascular mortality (HR, 5.98 [1.55 to 23.13] for the fourth versus the first quartile) and for patients with New York Heart Association class I and II (HR, 6.03 [2.07 to 17.52] for the fourth versus the first quartile). Conclusions - Circulating levels of NT-proBNP are a strong prognostic biomarker for patients with chronic stable angina.
