    AimsWe aimed to analyse the association between right haemodynamic parameters, right ventricular (RV) dysfunction parameters, and outcomes in patients with preserved ejection fraction (EF).Methods And ResultsRetrospective analysis of right haemodynamic (systolic pulmonary pressure and end-diastolic pulmonary pressure based on tricuspid regurgitation (TR) velocity at pulmonary valve opening time), and RV parameters including size (end-diastolic and end-systolic area), function (RV fractional area change, Tei index, Tricuspid Annular Plane Systolic Excursion, and speckle tracking derived free wall strain), from 557 consecutive patients with preserved EF [EF ≥ 50%; age 64.9 + 20; 52% female; co-morbidity Charlson index 4.7 (2.9, 6.4)]. All cause and cardiac mortality were retrospectively analysed and correlated to echo haemodynamic and co-morbid parameters. TR velocity at pulmonary valve opening time and calculated end-diastolic pulmonary artery pressure were obtainable in 71% of patients. The best haemodynamic univariate predictor of mortality was calculated end-diastolic pulmonary artery pressure [hazard ratio 1.06 (1.04-1.07); P < 0.0001], superior to TR peak velocity and systolic pulmonary artery pressure. Elevated end-diastolic pulmonary artery pressure was associated with all cause and cardiac mortality even when adjusted for all significant clinical (age, gender, and Charlson index), and echo (stroke volume index, left atrial volume index, systolic pulmonary pressure, E/e', and Tei index) parameters. Tei index was superior to all other RV functional parameters (P < 0.05 for all parameters).ConclusionTR velocity at pulmonary valve opening time and calculated end-diastolic pulmonary artery pressure are obtainable in most patients, and add prognostic information on top of clinical and routine haemodynamic and diastolic parameters.Published on behalf of the European Society of Cardiology.
