Abstract:
Objective To evaluate the outcome of incomplete revasculariszation by percutaneous coronary intervention (PCI) in elderly patients with coronary artery disease.Methods Data of 48 patients (age≥75 years old) underwent incomplete coronary revascularization during the period from 2008 to 2011 were collected.Their data before PCI and the 6 months follow-up results were comparatively analyzed.Results Six months after incomplete coronary revascularization,the LVEF was higher than that before revascularization ((48.10 ± 7.19)％ vs (39.82 ± 8.23)％) and BNP declined significantly ((575.17 ± 67.27) ng/L vs (793.57 ± 87.53)ng/L).T peak-T end (Tp-Te) √RR and Tp-Te/QT also declined significantly (Tp-Te √RR:(96.38 ± 10.79)ms vs (147.81 ± 17.32)ms;Tp-Te/QT:(0.25 ±0.05) vs (0.30 ±0.07)) (P ＜0.05).Six months after PCI,LVEDV and LVESV were higher than those before surgery,but there was no significant difference(P ＞ 0.05).Conclusion Incomplete coronary revascularization can improve heart function and stability of cardiac electrophysiology in elderly patients with coronary artery disease,but it can not prevent the development of left ventricular remodeling.
