Effect of Novel Cardiac Rehabilitation Training on Cardiac Function in Patients with Acute Myocardial Infarction after PCI Based on Enhanced Recovery After Surgery

ObjectiveTo investigate the effect of novel cardiac rehabilitation training on cardiac function in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI) based on enhanced recovery after surgery (ERAS).MethodsA total of 92 AMI patients admitted to the cardiology department of Dongying District People's Hospital from May 2020 to May 2023 were selected and randomly divided into control group and experimental group using a random number table method, with 46 patients in each group. Both groups received standardized symptomatic treatment and PCI surgery after admission. The control group received routine cardiac rehabilitation training in addition to the standardized treatment. On the basis of standardized treatment and routine cardiac rehabilitation training, the experimental group was given a new type of cardiac rehabilitation training based on ERAS. Peak power (PP), left ventricular end-systolic diameter (LVESD), and left ventricular ejection fraction (LVEF) were measured using a color echocardiography diagnostic instrument before training, after one month of training, and after three months of training; Cardiopulmonary Exercise Testing were used to assess exercise endurance, including exercise duration (ED), peak oxygen uptake (VO2), and anaerobic threshold (AT); N-terminal pro-brain natriuretic peptide (NT-proBNP) was measured using the Roche Cobas e411 chemiluminescence analyzer; superoxide dismutase (SOD) activity was measured using the xanthine oxidase method; malondialdehyde (MDA) expression level was measured using the thiobarbituric acid colorimetric method; total antioxidant capacity (T-AOC) was measured using the phenanthrene colorimetric method; expression levels of interleukin-18 (IL-18), nucleotide-binding oligomerization NOD-like receptor protein 3 (NLRP3), and interleukin-1β (IL-1β) were measured using the enzyme-linked immunosorbent assay, and expression level of nuclear factor kappa B (NF-κB) was measured using the enzyme-linked immunosorbent assay. Cardiopulmonary function was evaluated with the 6-Minute Walk Test (6MWT). The Myocardial Infarction Dimensional Assessment Scale (MIDAS) was used to evaluate the patients' quality of life.ResultsCompared with those before training, PP and LVEF increased in both groups after one month and three months of training (P
