Abstract:
Objective To investigate the characteristics and correlation between peak oxygen uptake(VO?peak)and heart rate recov-ery(HRR)during cardiopulmonary exercise test(CPET)in patients with coronary borderline lesions.Methods From January,2022 to January,2024,183 patients with coronary borderline lesions in Beijing Bo'ai Hospital were divided into low cardiorespiratory fitness(LCF)group(n=61),moderate cardiorespiratory fitness(MCF)group(n=62)and high cardiorespiratory fitness(HCF)group(n=60)based on VO?peak.Their characteristics and CPET parameters including VO?peak,exercise-phase heart rate(HR1,HR2,HR3),and post-exercise heart rate recovery(HRR1,HRR2,HRR3)were analyzed.Results After adjusting for age and body mass index,analysis of covariance showed that the peak heart rate,HR1,HR2 and HR3 were the lowest in LCF group(F>5.388,P<0.01).Repeated-measures analysis of variance showed that the inter-and intra-group effects were significant in HRR(F>14.561,P<0.001).Partial correlation analy-sis showed that VO?peak positively correlated with HRR1(r=0.404,P<0.001),HRR2(r=0.379,P<0.001)and HRR3(r=0.425,P<0.001).Conclusion In patients with coronary artery borderline lesions,VO?peak demonstrated a significant inverse correlation with HRR,the lower the VO?peak,the more delays of HRR.
