Topic: Risk, prevention and care in population studies
Background Impaired exercise tolerance during formal testing is predictive of perioperative complications. However, for most patients, formal exercise testing is not indicated, and exercise tolerance is assessed by history. Objective To determine the relationship between self-reported exercise tolerance and serious perioperative complications. Methods Our study group consisted of 600 consecutive outpatients referred to a medical consultation clinic at a tertiary care medical center for preoperative evaluation before undergoing 612 major noncardiac procedures. Patients were asked to estimate the number of blocks they could walk and flights of stairs they could climb without experiencing symptomatic limitation. Patients who could not walk 4 blocks and climb 2 flights of stairs were considered to have poor exercise tolerance. All patients were evaluated for the development of 26 serious complications that occurred during hospitalization. Results Patients reporting poor exercise tolerance had more perioperative complications (20.4% vs 10.4%; P Conclusion Self-reported exercise tolerance can be used to predict in-hospital perioperative risk, even when using relatively simple and familiar measures.

Key findings
- Results Patients reporting poor exercise tolerance had more perioperative complications (20.4% vs 10.4%; P Conclusion Self-reported exercise tolerance can be used to predict in-hospital perioperative risk, even when using relatively simple and familiar measures.
Why it matters
This study found that patients reporting poor exercise tolerance had more perioperative complications, but it does not address dementia or Alzheimer's disease. It is not relevant to treating, curing, or preventing Alzheimer's disease.
