The effect of left ventricular systolic function on maximal aerobic exercise capacity in asymptomatic patients with coronary artery disease.
Why the study?
Does left ventricular exercise reserve correlate with maximal aerobic exercise capacity in asymptomatic patients with coronary artery disease?
Population
27 asymptomatic patients with coronary artery disease able to attain true VO2max, mean age 50 +/- 10 years.

Implication
LV exercise reserve may refine capacity assessment over resting EF in asymptomatic CAD; hypothesis-generating for prognostic validation.
Structured PICO

P
Population
27 asymptomatic patients with coronary artery disease able to attain true VO2max, mean age 50 +/- 10 years.
I
Intervention
Maximal treadmill exercise testing with gated cardiac blood pool imaging
O
Outcome
Maximal O2 uptake (VO2max) and its correlation with left ventricular systolic function (ejection fraction at rest, peak exercise, and exercise reserve)surrogate
In asymptomatic patients with coronary artery disease, maximal aerobic exercise capacity is strongly determined by left ventricular exercise reserve rather than resting ejection fraction.
