A study on evaluation of heart function after percutaneous coronary intervention by real-time three-di-mensional echocardiography / 心血管康复医学杂志

ABSTRACT

Objective:To explore application value of real-time three-dimensional echocardiography (RT-3DE ) for heart function evaluation after percutaneous coronary intervention (PCI) .Methods:Clinical data of 45 patients with coronary heart disease (CHD) collected from Jan 2013 to Jan 2014 in our hospital were enrolled .All patients received selective coro-nary angiography (CAG) and PCI .Another 45 healthy cases undergoing physical examination during the same period were selected as normal control group .End-diastolic volume (EDV) ,end-systolic volume (ESV) ,left ventricular ejection frac-tion (LVEF) ,peak ejection rate (PER) and peak filling rate (PFR) were measured by RT-3DE and two-dimensional echo-cardiography (2DE) respectively and compared between two groups .Results:In normal control group ,there were no sig-nificant differences in all indexes between two measuring methods ,P>0.05 all;in CHD group ,compared with 2DE meas-ured value ,there were significant rise in EDV [ (130.6 ± 30.3) ml vs .(152.5 ± 35.2) ml] ,ESV [ (75.2 ± 21.8) ml vs . (94.1 ± 22.5) ml] ,PER [(2.41 ± 0.47) vs .(2.81 ± 0.39)] and PFR [(1.85 ± 0.25) vs .(2.13 ± 0.31)] ,and significant reduction in LVEF [ (45.8 ± 5.2)% vs .(41.6 ± 4.9)% ] in RT-3DE ,P<0.01 all;on one week ,one month and three months after PCI ,EDV and ESV gradually reduced ,LVEF ,PER and PFR gradually rose in CHD group with significant difference ,P<0.05 or <0.01 .Conclusion:RT-3DE can perform direct ,accurate and quantitative evaluation on heart form and function before and after PCI ,which is a reliable ,fast ,simple and new method evaluating PCI therapeutic effect in CHD patients .
