Pulmonary Hypertension in Left Heart Disease

Patients referred to the cardiac catheterization laboratory for invasive right heart catheterization for any reason.

Symptomatic HFpEF, defined by signs and symptoms of HF (dyspnea, fatigue), normal left ventricular (LV) EF (≥50% within 12 months of enrollment), and objective evidence of HF fulfilling at least one of the following criteria: Prior hospitalization for decompensated HF treated with intravenous diuretics; Invasively verified HFpEF defined by pulmonary capillary wedge pressure (PCWP) of ≥15 mmHg at rest and/or ≥25 mmHg during exercise; Clinical diagnosis of HFpEF that does not meet criteria i. or ii. but verified with NTproBNP>300 pg/ml in sinus rhythm or >900 pg/ml in AF; H2FPEF score ≥6 or HFA-PEFF score≥5 according to current guidelines.

Symptomatic HFrEF, defined by defined by signs and symptoms of HF (dyspnea, fatigue) and reduced EF (<50%).

Symptomatic valvular heart disease (VHD), defined by signs and symptoms of HF (dyspnea, fatigue) in tandem with clinically significant aortic or mitral valve disease (regurgitation and/or stenosis).
