About

CSWG App

This medical app provides three distinct calculators for clinical decision-making in cardiogenic shock. It helps assess shock stage, mortality risk, invasive hemodynamic parameters, and shock phenotypes for optimized patient care.

Highlights
  • Shock Stage Calculator
  • Invasive Hemodynamics Calculator
  • Congestion Profile Tracking
  • Shock Phenotype Calculator
  • Mortality Rate Predictions
  • Hemodynamic Parameter Calculations

The CSWG App is a comprehensive tool with three distinct parts and provides valuable calculators to assist clinical decision-making. Part 1: Cardiogenic Shock Working Group Shock Stage Calculator The first page of the app features the Cardiogenic Shock Working Group Shock Stage Calculator. This calculator utilizes the CSWG-SCAI shock stage classification system to determine the severity of cardiogenic shock. It provides an accurate assessment of the shock stage, along with the predicted mortality rate for each stage. Additionally, the calculator presents separate mortality predictions for myocardial infarction-related cardiogenic shock (MI-CS) and heart failure-related cardiogenic shock (HF-CS). Furthermore, it offers a predicted probability of stage escalation. Part 2: Invasive Hemodynamics Calculator The second page of the app houses the Invasive Hemodynamics Calculator. This powerful tool enables healthcare professionals to calculate various important parameters related to hemodynamics. With this calculator, users can determine parameters such as cardiac output using the Fick method, cardiac index, cardiac power output, cardiac power index, pulse pressure, aortic pulsatility index, systemic vascular resistance, mean pulmonary artery pressure, right atrial pressure/pulmonary capillary wedge pressure, pulmonary artery pulsatility index, right ventricular stroke work index, transpulmonary gradient, and diastolic pulmonary gradient. Additionally, the calculator generates a graph that plots left heart filling pressure (PCWP) and right heart filling pressure (CVP or RAP) to aid in the classification of parameters into categories such as "LV congestion," "RV congestion," "Hypovolemic," and "BiV Congestion." Part 3:Congestion Profile Tracking Plot left heart filling pressure (PCWP) and right heart filling pressure (CVP or RAP) to aid in the classification of parameters into categories such as "LV congestion," "RV congestion," "Hypovolemic," and "BiV Congestion." Plot points longitudinally to see trends over time. Part 4: CSWG-SCAI Shock Phenotype Calculator The final part of the app is the CSWG-SCAI Shock Phenotype Calculator. This calculator is designed to determine the shock phenotype based on specific characteristics and clinical indicators. It classifies the shock phenotype into three categories: phenotype I (non-congested), phenotype II (cardio-renal), and phenotype III (cardiometabolic). Additionally, the calculator provides a predicted in-hospital mortality rate for each phenotype, aiding clinicians in risk stratification and treatment planning. The CSWG App for iOS consolidates essential calculators and predictive capabilities in a user-friendly interface, offering a valuable resource for healthcare professionals involved in the management of cardiogenic shock. By facilitating accurate assessments, providing hemodynamic insights, and assisting in the determination of shock phenotypes, this app aims to optimize patient care and outcomes in the challenging context of cardiogenic shock. Please note that this app only presents data published in the literature and should not be a substitute for clinical decision making. The treating clinician/team should use their judgement and experience in clinical decision making.

CathPal is a comprehensive hemodynamic calculator for cardiac catheterization. Built by a cardiologist, for cardiologists. IMPORTANT — MEDICAL DISCLAIMER CathPal is an educational and decision-support tool intended for use by licensed healthcare professionals trained in cardiac hemodynamics. It is not a medical device. It does not diagnose disease, prescribe treatment, or replace clinical judgment. All calculated values must be interpreted in the context of the individual patient by a qualified physician. No clinical decision should be made based on the output of this app alone. If you are not a healthcare professional, do not use this app to make decisions about your own health or the health of another person. Always consult a qualified physician in addition to using this app and before making any medical decision. Never disregard professional medical advice or delay seeking it because of information obtained from this app. In an emergency, call your local emergency number immediately. All formulas, reference ranges, and thresholds in CathPal are drawn from peer-reviewed literature and professional society guidelines. Full citations — including the 2022 ESC/ERS Pulmonary Hypertension Guidelines, the 2020 ACC/AHA Valvular Heart Disease Guideline, and the original Gorlin, Hakki, LaFarge, Flamm, PAPi (Korabathina), CPO (Fincke), ARI (Sinning), and SCAI cardiogenic shock publications — are listed inside the app under "Disclaimer & References" and alongside each formula in the Equations view. Enter your catheterization data and instantly compute Fick and thermodilution cardiac output, pulmonary and systemic vascular resistance, RV performance indices, Gorlin and Hakki valve areas, and complete shunt quantification — all with an EMR-ready evaluation report you can copy and paste directly into the chart. HEMODYNAMIC CALCULATIONS • Fick cardiac output with LaFarge VO₂ estimation • Thermodilution CO with multi-run averaging • PVR, SVR, PVRI, SVRI (Wood units and dyn·s·cm⁻⁵) • PAPi, RVSWI, CPO, CPI — shock and RV performance indices • Pulmonary hypertension classification (2022 ESC/ERS criteria) • Cardiac index, stroke volume, stroke volume index VALVE AREAS • Gorlin equation for aortic (AVA) and mitral (MVA) valve areas • Hakki simplified formula (CO/√gradient) • AFib mode with per-beat averaging (up to 10 beats) • Automatic SEP and DFP calculation from ejection/filling times SHUNT QUANTIFICATION • Full oximetry run with step-up detection and localization • Qp/Qs ratio with absolute flow calculations • Shunt-adjusted PVR and SVR • Eisenmenger physiology warning SMART FEATURES • Auto-tab between pressure fields for rapid data entry • Quality checks flag impossible values and common entry errors • Algorithmic interpretation based on published guidelines • EMR-ready evaluation report with plain text (EHR) toggle • Dark mode support WORKS OFFLINE No account required.

Verdict

The call

The clearest difference is price: CSWG App at Free against CathPal's $4.99. CSWG App also leads on ratings volume (12 vs 2) and iOS requirement (16.0 vs 18.0). CathPal's advantage is update cadence (daily vs every 5 days). On rating, ads, in-app purchases and device support there is nothing between them.
