Abstract

Background:

Exercise capacity (EC) is the most powerful predictor of the presence and prognosis of coronary artery disease. EC is most commonly assessed by history taking.

Purpose:

To investigate how accurately patients and doctors predict patient EC.

Methods:

Prospective, multi-centre cohort study of 113 patients. Patients and referring doctors were asked to predict EC in METs from a list of activities (figure 1).

Results:

Patient demographics: 42% female, mean age 55, Indigenous Australians 26% (versus 11.3% of Cairns). Doctors: registrar (54%), cardiologist (18%), general practitioner (13%), general physician (9%), junior doctor (6%). Correlation with stress testing: Good correlation: 0.8. Patients: 0.49-0.47 (p<0.001), female/older patients were better. Doctors: 0.22-0.25, better for patients with diabetes/asthma.

Conclusion:

Doctor clinical questioning and patient reported EC has a poor correlation with actual EC in patients referred for a clinically indicated EST
