OBJECTIVES
Recent studies suggest that brain natriuretic peptide (BNP) is associated with the prognosis of coronary heart disease. We studied the relationship between BNP and left ventricular (LV) end-diastolic pressure and the number of involved coronary arteries in patients with chronic coronary artery disease.

STUDY DESIGN
The study included 100 patients (30 women, 70 men; mean age 56 years; range 37 to 78 years) who underwent coronary angiography for definite or suspected coronary artery disease. Before angiography, baseline serum samples were obtained for plasma BNP, and LV end-diastolic pressure was measured. The patients were classified in three groups as normal (n=35), one-vessel disease (n=16) and multivessel disease (n=49).

RESULTS
The incidence of diabetes mellitus and the levels of BNP and fasting blood glucose were significantly higher, and LV end-diastolic pressure and the mean heart rate were significantly increased in multivessel disease. Vessel involvement was significantly correlated with BNP (r=0.463, p<0.001), LV end-diastolic pressure (r=0.745, p<0.001), and fasting blood glucose (r=0.235, p<0.05). Correlation between BNP and LV end-diastolic pressure was highly significant (r= 0.72, p<0.001). Multivariate linear regression analysis showed LV end-diastolic pressure as the only independent determinant of increased BNP levels (r=0.762, p<0.001).

CONCLUSION
Increased plasma BNP levels are associated with increased LV end-diastolic pressure and increased vessel involvement in patients with chronic coronary artery disease.
