Objective  To investigate the efficicy of early cardiac rehabilitation procedures in treating patients after percutaneous coronary intervention.

  Methods  From August 2016 to August 2017, 51 patients underwent routine intervention forpercutaneous coronary intervention were selected as control group. From September 2017 to September 2018, 51 patients with early cardiac rehabilitation procedures for percutaneous coronary intervention were selected as observation group. The cardiac function before and after treatment, quality of life and the incidence rate of adverse cardiovascular events after 6 months of operation were compared between two groups.

  Results  After 2 weeks of intervention, the left ventricular ejection fraction (LVEF) in the observation group was significantly higher than that in the control group, and the levels of left ventricular end-systolic volume (LVESV), left ventricular end-diastolic volume (LVEDV) and wall motion integral index (WMSI) were significantly lower than those in the control group (P < 0.05). After 2 weeks of intervention, the scores of physiological function, physical pain, physiological function, emotional function, social function, energy, general health status and mental health in the observation group were significantly higher than those in the control group (P < 0.05). The incidence rate of malignant arrhythmia in the observation group was significantly lower than that in the control group (P < 0.05).

  Conclusion  Early cardiac rehabilitation procedures can improve cardiac function of patients with percutaneous coronary intervention, improve quality of life, and reduce cardiovascular adverse events.
