Why the study?
Does moderate supine exercise improve the sensitivity of systolic time intervals in detecting disordered hemodynamics in patients with coronary artery disease?
Population
65 subjects, comprising 33 normal subjects and 32 age- and sex-matched patients with coronary artery disease
Comparison
3 minutes of moderate supine exercise vs Resting state
Design
Cross-sectional
Follow-up
Immediately following 3 minutes of exercise

Exercise STI offers no added sensitivity in CAD; reinforces clinical assessment and leaves open any role for updated noninvasive indices.
Does moderate supine exercise improve the sensitivity of systolic time intervals in detecting disordered hemodynamics in patients with coronary artery disease?
Systolic time intervals measured during exercise do not provide additional sensitivity over resting measurements for detecting hemodynamic abnormalities in patients with coronary artery disease.
McConahay et al. (1972) studied this question.
