Heart Health Assessment for Pulmonary Hypertension

Inclusion Criteria: * Patients referred to the cardiac catheterization laboratory for invasive right heart catheterization for any reason. * Left Heart Disease, defined as one (or more) of the following: * 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). Exclusion Criteria: * Patient inability or unwillingness to undergo noninvasive echocardiography, or if echocardiography would, in the opinion of the investigator, somehow compromise the quality of data acquisition for the clinical case. * WSPH Group 1 Pulmonary hypertension or PH (Pulmonary arterial hypertension; including congenital heart disease) * Group 3 PH (Hypoxia/Lung disease-related PH) * Group 4 PH (Thromboembolic PH) * Group 5 PH (Miscellaneous) * Clinically significant parenchymal lung disease, hypoxemia, or lung infection * Amyloid/infiltrative cardiomyopathy * Acute Myocarditis * Acute coronary syndrome or revascularization within 90 days * Use of PH-specific drugs * Constrictive pericarditis * High output heart failure * HF hospitalization within the preceding 30 days * Severe or greater aortic (AVA \< 1.0 cm2, Mean Gradient \> 40 mmHg) or severe mitral (MVA \< 1.0 cm) stenosis * Inability or unwillingness to exercise * Inadequate echocardiographic imaging windows * Inability or unwillingness to cooperate with breath holding
