Abstract:
Objective To evaluate the influence of percutaneous coronary intervention (PCI) on NT-proBNP and Hs-CRP level of the elderly with coronary heart disease. Methods Twenty-four patients who underwent PCI, and thirty patients who underwent coronary angiography (CAG) were enrolled in this study. Plasma NT-proBNP and Hs-CRP concentrations before and at 0, 1 h, 24 h and 72 h after PCI were assayed in all patients. Results There were no significant difference in plasma NT-proBNP level at baseline level between the PCI and CAG group, and also no significant change in the CAG group after the procedure. Plasma NT-proBNP level was increased significantly from 231.31?233.52 pg/mL to the peak concentration of 663.75?614.93 pg/mL at 24 h after PCI. Statistical differences were observed between the baseline levels and at 24 h as well as 72 h after the operation in the PCI group. Plasma NT-proBNP concentrations also showed significant differences between the PCI and CAG group at each time point after the procedures. Remarkable elevation in plasma Hs-CRP level was observed at 72 h after procedure in all patients. Conclusion Elevation of plasma NT-proBNP concontrations might be induced by transient myocardial ischemia in PCI. NT-proBNP may be a marker of myocardial ischemia and may be useful to detect untypical ischemia in the elderly. Plasma Hs-CRP increased at 72 h after PCI and CAG, which may be related to inflammation reaction induced by vessel puncture.
