REVEAL 2.0 Risk Score: Explanation and Clinical Context The REVEAL 2.0 Risk Score (Registry to Evaluate Early and Long-term PAH Disease Management 2.0) is a validated and widely used prognostic model developed to estimate 1-year mortality in patients with pulmonary arterial hypertension (PAH). It is based on the large U.S. REVEAL registry and integrates demographic, clinical, laboratory, echocardiographic, and hemody
REVEAL Lite 2 Risk Score: Explanation and Clinical Context REVEAL Lite 2 is a simplified, non-invasive risk assessment tool for patients with pulmonary arterial hypertension (PAH). It is derived from the original REVEAL 2.0 registry and validated to provide reliable prediction of 1-year mortality using only six readily available clinical variables: WHO Functional Class, systolic blood pressure, heart rate, 6-minute w
Right Atrial Pressure Estimation Using IVC Diameter and Collapse Estimating right atrial pressure is an essential part of echocardiographic assessment because it directly influences the calculation of pulmonary artery systolic pressure and provides insight into right sided cardiac filling. The widely adopted method is based on the diameter of the inferior vena cava and its collapsibility with inspiration. A small ven
