Abstract:

Objective To investigate the characteristics and correlation between peak oxygen uptake (VO2peak) and heart rate recovery (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 VO2peak. Their characteristics and CPET parameters including VO2peak, 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 analysis showed that VO2peak 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, VO2peak demonstrated a significant inverse correlation with HRR, the lower the VO2peak, the more delays of HRR.
