Abstract:
Objective:To investigate effects of resistance exercise on exercise tolerance,cardiac function and somati-zation symptoms in patients with stable coronary artery disease(SCAD).Methods:SCAD patients without heart failure,who were diagnosed with coronary angiography or coronary CTA in Second Affiliated Hospital of Baotou Medical College,Inner Mongolia University of Science & Technology between June 2020 and June 2022 were select-ed.They were enrolled into groups according to voluntary principle,and 47 cases and 58 cases were finally included in control group and resistance exercise group respectively.Both groups exercised for 12 weeks according to the ex-ercise prescription.Exercise tolerance was assessed using peak oxygen uptake(VO2peak)and anaerobic threshold;left ventricular diastolic function was assessed using cardiac echocardiography mitral early-diastolic peak flow ve-locity/late-diastolic peak flow velocity(E/A);and mental health was assessed using Somatization Symptom Self-rating Scale(SSS).The occurrence of serious cardiovascular adverse events was compared between two groups after 24-week follow-up.Results:Compared with before exercise,after 12-week exercise,there were significant rise in VO2 peak[(17.53±3.92)ml·min-1·kg-1 vs.(20.35±3.70)ml·min-1·kg-1],anaerobic threshold[(11.60±3.40)ml·min-1·kg-1 vs.(12.62±3.16)ml·min-1·kg-1],E peak[(0.63±0.14)mm/s vs.(0.70±0.16)mm/s]and E/A ratio[(0.80±0.14)vs.(0.91±0.24)];and significant reductions in resting heart rate[(76.21±12.70)beats/min vs.(74.36±9.87)beats/min]and SSS score[10.00(5.00,22.25)points vs.9.50(3.00,21.00)points]in resistance exercise group(P＜0.01 all).Compared with the control group,VO2 peak[(18.59±3.93)ml·min-1·kg-1 vs.(20.35±3.70)ml·min-1·kg-1]and E/A ratio[(0.82±0.22)vs.(0.91±0.24)]were significantly higher in resistance exercise group after 12 weeks(P＜0.05 both).After 24-week follow-up,there was no significant difference in incidence rate of serious cardiovascular adverse events between two groups(P=1.000).Conclusion:Resistance exercise can significantly increase exercise tolerance,improve cardiac diastolic function and psychological health in patients with coronary artery disease.
