Eur J Prev CardiolPublished

  • Prospective cohort study
  • nationwide population-based
  • inverse probability-weighted

Authors' conclusion

Aerobic exercise maintenance after PCI was associated with a reduced risk of cardiovascular events in patients with diabetes, with a moderate amount of exercise providing maximal benefit.

Study context

Population
Patients with DM undergoing Percutaneous Coronary Intervention (PCI), Korean National Health Insurance System
Participants
8,225 patients
Exposure
Aerobic exercise habit change before vs after PCI
Outcome
Major adverse cardiovascular events (MACE):
  • All-cause death
  • MI
  • Revascularization
  • HF
Follow-up
Mean 4.9 years

Main finding

As reported in the abstract

Each group vs persistent non-exercisersAdjusted hazard ratio (95% CI)
Exercise maintainers
0.78(0.71–0.86)
Exercise discontinuers
0.88(0.79–0.98)
New exercisers
0.89(0.80–1.00)

Observational data: associations, not effects.

Further findings

Amount of aerobic exercise and adverse outcomes

J-curve relationship; lowest risk at 1000-1499 MET-min/week
Benefits diminished with ≥1500 MET-min/week
