Do right and left ventricular myocardial perfusion reserves correlate with right ventricular function and pulmonary hemodynamics in patients with pulmonary arterial hypertension?
Reduced myocardial perfusion reserve is inversely correlated with RV workload and ejection fraction, suggesting it may contribute to RV dysfunction in PAH.
Biventricular vasoreactivity is significantly reduced with PAH and inversely correlated with RV workload and ejection fraction, suggesting that reduced myocardial perfusion reserve may contribute to RV dysfunction in patients with PAH.
Vogel‐Claussen et al. (Sat,) studied this question.
