The impact of percutaneous coronary intervention on left heart failure in patients with coronary heart disease

Objective To explore the impact of percutaneous coronary intervention (PCI) on left heart failure in patients with coronary heart disease.Methods Sixty-two patients with coronary heart disease combined with left heart failure underwent PCI (PCI group)were studied,and 60 patients with the similar condition treated by drugs were served as control(control group).Both the two groups were detected by echocardiography before and six months after received treatment.Left ventricular end-diastolic diameter (LVDd),left ventricular end-systolic diameter (LVDs),left ventricular ejection fraction (LVEF),left ventricular fractional shortening (FS) and NYHA grading according to clinical manifestation were compared.Results LVDd,LVDs,LVEF,FS and NYHA grading were all improved 6 months after treatment in two groups.Aforementioned indexes of heart function in PCI group were significantly improved than those in control group(all P0.01).Conclusions The left ventricular function in patients with coronary heart disease is significantly improved after PCI.
