ABSTRACT

Objective:To investigate the long effect of pereutaneous coronary intervention(PCl)on heart rate variability(HRV) in patients with coronary artery disease(CAD),and to evaluate the prognosis of patients with CAD receiving PCI.Methods:To choose 32 patients confirmed by coronary arteriography and suitable for PCl,and to choose 32 control patients with non-CAD confirmed by coronary arteriography,HRV indices were analyzed hefore PCI and Iweek,Imonth,3months,6months,lyear after PCI.Results:HRV indices were decreased in patients with CAD,HRV was lower in patients in lweek after PCI than that before PCI,HRV was gradually increased in lmonth and there was significantly improved in 6months after PCI,and nearly to the level of control group in one year.Conclusion:HRV is low in the patients with CAD,there is slightly decreased in the early stage of PCl,but the long effect of PCI on heart rate variability can be observed.
