Heart rate recovery after exercise and long-term prognosis in Algerian patients with coronary artery disease - 09/01/21
Résumé |
Background |
The long-term prognostic value of heart rate recovery (HRR) has been incompletely documented in patients with coronary artery disease (CAD). We sought to confirm the prognostic value of HRR in Algerian cohort with stable CAD.
Methods |
We identified 720 patients with baseline exercise stress testing data. HRR was measured at 3minutes post exercise during a passive recovery. Clinical outcomes were evaluated according to HRR in both threshold and continuous models.
Results |
Median long-term follow-up was 3.7 years. HRR<45 beats per minute (Bpm) most appropriately differentiated non survivors from survivors and was associated with an increased risk of all-cause death (adjusted hazard ratio=1.17; P=0.001). Increasing HRR was associated with a lower risk of all-cause (adjusted hazard ratio=0.93 per 10 Bpm;) and cardiovascular (CV) mortality (adjusted hazard ratio=0.94 per 10 Bpm;).
Conclusions |
HRR at 3minutes independently predicts long-term all cause and CV mortality in patients with stable CAD. Measurement of HRR at 3minutes during passive recovery can be used as a complementary tool to identify patients with a higher total and CV risk.
