Abstract:
Objective: To explore the relationship between plasma level of N terminal pro brain natriuretic peptide (NT-proBNP) and severity of coronary artery lesion in patients with coronary heart disease (CHD). Methods: A total of 206 patients suspected CHD, who admitted from Jan 2010 to Jun 2012 in our department and underwent coronary angiography (CAG), were divided into single vessel coronary disease group (n=54), double-vessel coronary disease group (n=52), multi-vessel coronary disease group (n=67) and normal group (n=33), according to CAG examination; and divided into acute myocardial infarction (AMI) group (n=45), unstable angina pectoris (UAP) group (n=91), stable angina pectoris (SAP) group (n=43) and normal group (n=27) according to clinic symptom. All patients received measurement for NT-proBNP, creatine kinase-isoenzyme (CK-MB) and cardiac troponin I (cTnI). Stenotic severity of coronary artery lesion was evaluated using Gensini score method. Data of all groups were analyzed statistically. Results: Compared with SAP group and normal group, there was significant increase in plasma level of NT-proBNP [(2.28±0.22) vs. (2.18±0.69) vs. (2.94±0.24) vs. (2.74±0.15), P<0.01 or P<0.05] in AMI group and UAP group. Compared with normal group, there was significant increase in plasma level of NT-proBNP [ (2.07±0.43) vs. (2.44±0.38) vs. (2.69±0.34) vs. (2.98±0.28), P<0.05] in single, double and multi-vessel coronary disease groups. Plasma level of NT-proBNP was positively correlated with Gensini score (r=0.51, 0.67, 0.73 respectively in single, double and multi-vessel coronary disease group, P<0.05 all). Conclusion: NT-proBNP concentration can be regard as an index predicting severity of coronary artery lesion.
