Trusted for over 15 years by heart rhythm professionals worldwide, epTools is a collection of useful tools for the evaluation of heart rhythm disorders. It is available on iPhone and iPad devices. Resources include algorithms used to localize arrhythmia substrates and reference guides to assist in the identification and, management of cardiac rhythm disorders and tools to calculate commonly used measurements and risk scores. Peer-reviewed algorithms are implemented by tools via an intuitive user interface. References are provided. Tools guide the user or AI through a series of questions to arrive at an answer while providing a graphical visualization of their progress and result of their analysis. Use of the save path to image feature allows users to save an image of the current decision path when using many of the decision analysis tools included. These images, which appear in the photo album, may be useful to communicate findings with colleagues.

About

DAPT Risk Calculator

This tool helps clinicians assess the risk and benefit of continuing dual antiplatelet therapy (DAPT) for patients at least 12 months post-PCI. It provides a numerical DAPT Risk Score and calculates the percentage risk for key cardiovascular events.

Highlights
  • DAPT Risk Score calculation
  • Risk/benefit analysis for DAPT continuation
  • Percentage risk for MI
  • Percentage risk for Stent Thrombosis/MACCE
  • Percentage risk for Bleeding
Features
Read full description

The ACC DAPT Risk Calculator provides clinical decision support for clinicians evaluating the continuation of DAPT therapy for patients at least 12 months post-PCI procedure, and the risk/benefit of continuing or discontinuing DAPT. The App provides a DAPT Risk Score as a numerical value between -2 and +9, where a Higher DAPT scores suggest that the benefit/risk ratio with prolonged DAPT may be favorable. Conversely, lower DAPT scores suggest that the benefit/risk ratio with prolonged DAPT is NOT favorable. The clinical decision support tool also calculates the percentage of risk for three end points: - Myocardial infarction (MI) - Stent thrombosis, major adverse cardiovascular and cerebrovascular events (MACCE) - Bleeding

Verdict

The call

The clearest difference is price: DAPT Risk Calculator at Free against epTools's $19.99. DAPT Risk Calculator also leads on iOS requirement (13.0 vs 16.0). epTools's advantage is ratings volume (519 vs 2) and update cadence (every 4 months vs every 17 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
