| Objective:To investigate the effect of individualized exercise therapy guided by 6-minute walking test on cardiac function, quality of life and short-term prognosis in patients with coronary heart disease without revascularization.Methods:The patients who were hospitalized in the Department of Cardiology of our hospital and confirmed by coronary angiography that there was at least one or more coronary artery stenosis more than 75%, but not given vascularization of the coronary artery were selected for study. They were divided into routine drug therapy group (group A) and routine drug therapy plus exercise rehabilitation group (group B). Patients in group B received rehabilitation exercise guided by 6 minute walk test. The quality of life, cardiac function and prognosis of the two groups were compared after treatment for 8 weeks.Results:After 8 weeks of treatment, the heart failure rate, recurrent myocardial infarction rate and mortality were significantly lower in group B than in group A (P<0.05). After treatment, the resting wall motion scores and quality of life scores in the two groups significantly decreased as compared with those at the time of discharge (P<0.05), and those in the group B decreased more obviously than in the group A (P<0.05); the left ventricular ejection fraction in the two groups and the distance of 6 min walking test were significantly improved as compared with those at the time of discharge (P<0.05), and those in the group B were improved more obviously than in the group A.Conclusion: The individualized exercise therapy guided by 6 minute walk test can obviously improve the heart function, quality of life and the short term prognosis of patients with coronary heart disease without revascularization. |
