Everything at the point of decision.

Three ACC Appropriate Use Criteria documents, fully transcribed and cross-checked. Landmark trials at fellow depth. Calculators validated against published worked examples.

Appropriate Use Criteria

Diagnostic testing and coronary revascularization, scenario by scenario — the 2023 CCD multimodality, 2017 SIHD, and 2016 ACS documents. Guided flows or full tables, every modality rating side by side.

Evidence library

Landmark trials summarized at study-companion depth — question, design, result, and what it means at the bedside — each linked to the AUC scenarios it informs. New trials are added over time.

Calculators

PREVENT, GRACE, cath-lab hemodynamics, valve areas, lipids, perioperative risk and more — every formula validated against its published worked example and computed entirely on device.

Rigor you can check

Only reproducible, published models are implemented — proprietary scores link out, never cloned. Two-tier input plausibility limits catch typos and unit errors before they become wrong answers.

Privacy

iCath collects nothing.

No accounts, no analytics, no ads, no tracking. Every calculator is stateless — nothing you enter is ever stored or transmitted. Patient data never touches the app, by design.

Made by a cardiologist,
for cardiologists.

iCath is written and maintained by Weston Hickey, MD, FACC, FSCAI — an interventional cardiologist in Houston. Every rating, summary, and formula is checked against its primary source.
