Effect of Early Respiratory Function Training Combined with Stage Rehabilitation Plan on Cardiopulmonary Reserve in Patients with Myocardial Infarction after PCI Recanalization
Objective:To investigate the effect of early respiratory function training combined with stage rehabilitation program on cardiopulmonary function in patients with acute myocardial infarction(AMI)who underwent recanalization after percutaneous coronary intervention(PCI).Methods:ln this study,a prospective randomized clinical trial was conducted to select 97 AMI patients who received PCI from July 2019 to December 2021 and whose coronary target vessel recanalization standard reached thrombolysis in myocardial infarction(TIMI)level 3.According to the random number table method,the patients were divided into combined group(48 cases)and conventional group(49 cases).The patients in combined group received early respiratory function training combined with stage rehabilitation plan to implement postoperative rehabilitation,and the patients in conventional group only received general clinical rehabilitation guidance and early respiratory function training.The cardiac function index,cardiopulmonary exercise test index,Seattle Angina Rating Scale(SAQ)score,and 6-minute walking distance between the two groups were compared.Results:After intervention,the left ventricular ejection fraction(LVEF)of combined group was higher than that of conventional group,and the left ventricular end-systolic volume(LVESV)and left ventricular end-diastolic volume(LVEDV)were lower than those of conventional group,and the differences were statistically significant(P＜0.05).After intervention,the peak oxygen uptake(peak VO2),peak work rate(peak WR),oxygen consumption of anaerobic threshold value(VO2AT),and 6-minute walking distance of the combined group were greater than those of the conventional group,and the differences were statistically significant(P＜0.05).After the intervention,the degree of physical activity limitation,the satisfaction with disease treatment,and the total score of SAQ in combined group were higher than those in conventional group,and the differences were statistically significant(P＜0.05).Conclusion:Early respiratory function training combined with stage rehabilitation plan can significantly improve the cardiopulmonary function and quality of life of patients with AMI after PCI.
