Title: The Effect of PCI on Left Ventricular Systolic function in patients with left Ventricular dysfunction and CTO and collateral circulation
Abstract: Objective:To evaluate the effect of percutaneous coronary intervention(PCI)on improvenent of left ventricular systolic function in patients with chronic total occlusion(CTO)and collateral circulation and left ventricular dysfunction.Methods:From January 2001 to December 2003,36 patients with chronic total occlusion and collateral cirulation and left ventricular dysfuction by coronary artery angiography were enrolled in this study. 30 cases were treated by PCI, in which 24 successful cases were listed as relink group,6 unsuccessful cases and 6 not PCI′s cases were listed as non-link group.The two dimensional echocardiography(2DE) was performed on each patients before and after PCI.Results:The clinical symptoms and the LVEF of the 24 successful cases were better than those before PCI, and three months later the improvenent became much more apparent. Compared with the non-link group, the LVEF also improved apparently.Concluison:The patients with left ventriculas dysfunction and CTO and collateral circulation could get benefit from PCI.
