摘要Background Stable angina pectoris is a common subtype of coronary heart disease.Patients suffer from chest tightness,chest pain and crushing pain under the inducement of fatigue and emotional agitation.This study aims to investigate the effect of exercise training guidance based on action research on exercise endur-ance and readmission rate of patients with stable angina pectoris.Methods A retrospective study was con-ducted on 60 patients with stable angina pectoris due to coronary heart disease admitted to our hospital from February 2020 to November 2023.Patients were divided into a control group of 29 cases(receiving conven-tional exercise training guidance)and a guidance group of 31 cases(receiving action research-based exercise training guidance).Both groups received continuous training for one month.A comparison was made between the exercise endurance indicators[6-minute walk test distance(6MWT),peak oxygen consumption(peakVO2),anaerobic threshold(AT),exercise duration(ED)],quality of life,and readmission rate within 6 months after intervention in both groups.Results After 1 month of intervention,6MWT,peakVO2,AT and ED were in-creased in both groups,and those in the guidance group were higher than those in the conventional group(P＜0.05).The score of quality of life(The 36-item shot-form health status survey,SF-36)in both groups was in-creased,and the guidance group scored higher than the conventional group(P＜0.05).The readmission rate of patients in the guidance group was 6.45％,which was lower than that in the conventional group(27.59％)(P＜0.05).Conclusions The application of action research-based exercise training guidance in patients with sta-ble angina pectoris due to coronary heart disease has significant effects,improving exercise endurance,signifi-cantly improving quality of life,and reducing readmission rate,thus having practical value.[S Chin J Cardiol 2024;25(3):162-168]
