Why the study?

Improper exercise can increase cardiovascular risk in older patients with coronary heart disease, highlighting the need for clinical evidence on CPET-guided cardiac rehabilitation after PCI.

Does CPET-guided cardiac rehabilitation improve exercise tolerance in older persons (≥75 years) with coronary heart disease after PCI?

Structured PICO

Does CPET-guided cardiac rehabilitation improve exercise tolerance in older persons (≥75 years) with coronary heart disease after PCI?

Population

403 older persons (aged ≥75 years, mean age 80.5±4.3, 75.6% male) with coronary heart disease who underwent successful percutaneous coronary intervention (PCI) and CPET-guided cardiac rehabilitation. Exclusion criteria included positive exercise ECG, NYHA class III-IV, malignant arrhythmia, valvular heart disease, and history of CABG.

Intervention

Cardiopulmonary exercise testing (CPET)-guided cardiac rehabilitation, with individualized exercise intensity prescribed using the anaerobic threshold heart rate ±5 bpm. Recommended moderate-intensity continuous aerobic exercise (walking, cycling, swimming) 3-5 days per week for 30-60 minutes per day.

Outcome

Change in patients' exercise tolerance, represented by VO2peak and other CPET parameters during the follow-up periodsurrogate

Limitations

Single-centre study with limited generalizability
Retrospective design without prospective interventional research
Included patients had few comorbidities and were able to cooperate, which may not apply to those with multiple comorbidities or bedridden status
High amount of missing data regarding quality-of-life scores (SF-36)

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

May support safer CPET-guided rehab in older post-PCI patients; leaves open need for RCTs to confirm benefit.
