Explanation and Clinical Context Echocardiography hemodynamics integrates Doppler derived flow, structural measurements, and chamber velocities to estimate stroke volume, cardiac output, filling pressure, and right atrial pressure. LVOT VTI with a measured LVOT diameter yields stroke volume using the continuity principle. Inferior vena cava size and respiratory variation provide an estimate of right atrial pressure a
EPIPHANY Index (Pulmonary Embolism in Cancer): Explanation and Clinical Context The EPIPHANY Index is a prognostic tool developed for patients with active cancer who present with pulmonary embolism. It estimates the risk of 30-day serious complications, including mortality, hemodynamic instability, or need for intensive care interventions. The score integrates clinical parameters available at presentation: oxygen sat
ESC/ERS 2022 Pulmonary Arterial Hypertension Risk Table: Explanation and Clinical Context The ESC/ERS 2022 Risk Table provides a multiparametric assessment model for estimating the 1-year mortality risk in patients with pulmonary arterial hypertension (PAH). It integrates clinical, functional, biomarker, and hemodynamic data to categorize patients into Low (<5%), Intermediate (5–20%), or High (>20%) risk groups. Key
ESCAPE Trial Hemodynamic Congestion Index: Rationale, clinical meaning, and evidence The Hemodynamic Congestion Index (HCI) implemented here is the simple sum of right atrial pressure (RAP) and pulmonary capillary wedge pressure (PCWP): HCI = RAP (mmHg) + PCWP (mmHg). This index was derived from analyses of the ESCAPE trial dataset and related secondary analyses that examined whether a single composite invasive press
EuroSCORE Calculator EuroSCORE: Comprehensive Explanation and Clinical Context The European System for Cardiac Operative Risk Evaluation, or EuroSCORE, is a validated clinical tool designed to estimate operative mortality in patients undergoing cardiac surgery. It incorporates demographic factors, comorbidities, hemodynamic status, and specific cardiac or surgical risk features. The model was originally derived from
