    The study analyzed heart rate recovery (HRR) and oxygen uptake (VO₂) recovery in 200 patients with stable coronary artery disease (CAD).

  • 2

    Significant correlations were found between HRR at 1 minute and both ΔVO₂ values and VO₂ recovery indices, indicating interdependence of recovery metrics.

  • 3

    Distinct recovery phenotypes were identified, revealing heterogeneity in post-exercise recovery dynamics among CAD patients.

  • 4

    The Good HRR–Poor VO₂ phenotype exhibited significantly lower VO₂ recovery compared to the Poor HRR–Good VO₂ phenotype.

  • 5

    The study suggests that integrated assessment of HRR and VO₂ recovery may enhance characterization of recovery before cardiac rehabilitation.
