Effect of elective percutaneous coronary intervention on left ventricular function in patients with coronary artery disease.

Coronary artery disease is one of the most common causes of mortality and morbidity across the world. Its treatment includes medical treatment, coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI). The purpose of this study was to investigate the effect of PCI on echocardiographic findings of left ventricular (LV) systolic and diastolic function. 115 patients with coronary artery disease candidate for PCI were enrolled to our study. Echocardiography was done before PCI, the day after and 3-6 months later. LV systolic and diastolic function were measured and recorded. Echocardiographic finding compared with repeated measurement analysis. Mean age of the patients was 57.8 ± 8.38 years. The mean ejection fraction (EF) was (%40.52 ± 6.36) before, (%41.83 ± 7.14) the day after, and (%44.0 ± 7.89) 3-6 months after PCI. Diastolic dysfunction were mild to moderate before PCI, which in %74 (86 patients) were improved to mild dysfunction the day after PCI but not changed 3-6 months later (P<0.0001). PCI improved LV ejection fraction, and LV diastolic function in our patient's population.
