Abstract:
Objective To explore the relationship of plasma level of B-type natriuretic peptide (BNP) with cardiovascular risk,the severity of coronary heart disease(CHD),and the short-term prognosis in patients with type 2 diabetes. Methods 154 patients with type 2 diabetes,of them 95 cases complicated with CHD and 65 with hyper-tension were selected in this study. The CHD patients were diveded into 3 groups: AMI(n=32), UAP(n=33) and SAP(n=30). The relationship of the plasma BNP levels with cardiovascular risks, with each coronary heart disea-ses,were observed. The patients were followed up for 6 months to study the predicting role of BNP on the death in pa-tients accompanied with CHD. Results The plasma BNP level was (397.34±217.79) ng/L, which was correlated with age, CRP, hypertension and CHD (r=0.631,0.672, 0.762,0.857, P<0.05 for each);the plasma BNP levels increased with age(r=0.896,P<0.01):(57.6±12.3) ng/L in patients <50 years old,(146.2±53.4)ng/L in patients 50≤and < 59 years old, (388.4±67.5) ng/in patients 60≤and < 69 years old, and (423.8±132.6) ng/L in patients≥70 years old (P<0.01 or P<0.05). The plasma BNP levels, was higher in patients with hyper-tension than that in patients without hypertension [(314.7±125.3) ng/L vs (136.8±98.7) ng/L, P<0.01];Higher in patients with CHD than that in patients without CHD [(425.03±200.80)ng/L vs (37.64±21.57) ng/L,P<0.01)]. The short-term prognosis of patients with CHD was correlated with the levels of BNP, and BNP levels≥485 ng/L may be an independent predicting factor for cardiac death within one month. Conclusions Plas-ma levels of BNP were associated with some cardiovascular risks,which may be one of biomarkers for cardiovascular risks in patient complicated with CHD.
