Dataset for: Ventriculo-Arterial Coupling Detects Occult RV Dysfunction in Chronic Thromboembolic Pulmonary Vascular Disease

Chronic thromboembolic disease (CTED) is sub-optimally defined by a mean pulmonary artery pressure (mPAP) 0.68 and Ees/Ea < 0.68 sub-groups demonstrated constant RV stroke work but lower stroke volume (87.7±22.1 vs. 60.1±16.3mL respectively, p=0.006) and higher end-systolic pressure (36.7±11.6 vs. 68.1±16.7mmHg respectively, p<0.001). Lower Ees/Ea in CTED also correlated with reduced exercise ventilatory efficiency. Low Ees/Ea aligns with features of RV maladaptation in CTED both at rest and on exercise. Characterisation of Ees/Ea in CTED may allow for better identification of occult RV dysfunction.
