OBJECTIVE: To investigate the effect of early home-based cardiac rehabilitation (CR) exercise on the prognosis of patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI).
METHODS: The clinical data of 115 patients with AMI in our hospital were collected retrospectively. All patients underwent PCI and were divided into group A (n=57) and group B (n=58) according to postoperative intervention. Patients in group A only received routine rehabilitation guidance, while those in group B received early home-based CR exercise. The incidence of postoperative complications, cardiac function index, 6-minute walking distance (6MWD), cardiac antioxidant index, exercise endurance index and quality of life score were compared between the two groups before and after intervention.
RESULTS: Compared with those in group B, patients in group A showed a lower incidence of postoperative complications (17.54% vs. 3.45%, P<0.05). After intervention, group A had lower left ventricular ejection fraction (LVEF), left ventricular end systolic diameter (LVESD) and left ventricular end diastolic diameter (LVEDD), longer 6MWD, higher total antioxidant capacity (T-AOC) and superoxide dismutase (SOD), lower malonaldehyde (MAD), higher exercise duration (ED), anaerobic threshold (AT) and VO2 and higher scores of quality of life than group B (P<0.05).
CONCLUSION: Early home-based CR exercise in patients with AMI after PCI can improve cardiac function, reduce the incidence of postoperative complications as well as enhance cardiac antioxidant capacity, exercise ability and quality of life.
