ABSTRACT
Objective: To explore value of exercise stress test guiding aerobic exercise rehabilitation in patients with myocardial infarction.Methods: A total of 102 patients with myocardial infarction in recovery were selected.According to random number table, they were randomly and equally divided into routine rehabilitation group (received routine rehabilitation guidance) and aerobic exercise rehabilitation group (received aerobic rehabilitation exercise in guidance of exercise stress test).Amount of exercise, hemodynamic parameters and psychological state were compared between two groups.Results: After treatment, amount of exercise: compared with routine rehabilitation group, there were significant rise in amount of exercise[(6.79±0.58)METs vs.(7.42±0.69)METs], maximum heart rate[(126.27±5.26) beats/min vs.(138.18±5.81) beats/min], heart rate blood pressure product[(221.87±21.46) vs.(244.85±23.09)]and exercise duration[(10.36±1.36) min vs.(11.18±1.45) min]in aerobic rehabilitation group, P<0.05 or <0.01;hemodynamic parameters: compared with routine rehabilitation group, there were significant rise in cardiac output[(5.36±0.57) L/min vs.(5.72±0.68) L/min], cardiac index[(2.96±0.53) L min-1 m-2 vs.(3.25±0.52) L min-1 m-2], stroke volume[(73.16±8.47) ml vs.(78.12±9.14) ml]in aerobic exercise rehabilitation group, P<0.05 all;psychological state: compared with routine rehabilitation group, there were significant reductions in scores of Hamilton rating scale for anxiety[HAMA, (9.74±3.26) scores vs.(6.35±1.18) scores]and Hamilton rating scale for depression[HAMD, (14.83±4.58) scores vs.(10.56±3.27) scores]in aerobic exercise rehabilitation group, P<0.05 both.Conclusion: Exercise stress test guiding aerobic exercise rehabilitation can help to improve exercise function and hemodynamic indexes, alleviate the negative mood, then promote patients recover.
