Methods One hundred and five patients with CHD and normal ventricular function were enrolled. Blood samples for assessment of NT-proBNP and cTn-T were collected before and after PCI. Results The mean left ventricular ejection fraction was 60.3 ± 5.3%. After revascularization, the level of lgNT-proBNP was signifi-cantly reduced (2.40 ± 0.44 vs 2.23± 0.43, P 〈 0.001). Subgroup analysis showed that the level of lgNT-proB-NP ws consistently decreased in different clinical classifications (stable angina: 45, unstable angina: 31 and acute myocardial infarction: 29) and target-vessel revascularization (left anterior descending artery: 30, left cir-cumflex artery: 26 and right coronary artery: 49), and in 99 patients without elevation of post-procedural cTn- T, but it showed a trend of non-significant increase in 6 patients with elevated cTn-T. Conclusions Our study demonstrates that successful PCI reduces plasma NT-proBNP concentration in patients with CHD and normal ven-tricular function. This implicates that the impact of PCI should be considered in the interpretation of NT-proBNP change in clinical practice, and further studies are necessary to investigate the direct and/or indirect effect of myocardial ischemia on BNP/NT-proBNP.展开更多
