RV reserve abnormalities in CAD may reflect LV rather than isolated RV ischemia; leaves open independent prognostic value of exercise RV assessment.
Does upright bicycle exercise reveal abnormal right ventricular ejection fraction responses in patients with coronary artery disease?
Abnormal right ventricular reserve during exercise is common in coronary artery disease and appears to be primarily driven by the concomitant left ventricular response rather than proximal right coronary stenosis.
Berger et al. (1979) studied this question.
