About

The CARDIOSTORY.TN study is a prospective observational study at Sahloul University Hospital (Sousse, Tunisia) evaluating the CardioStory device for distinguishing heart failure (HF) from other causes of acute dyspnea.

Background: Dyspnea is common in emergencies, and differentiating cardiac from non-cardiac causes is often delayed by the limits of echocardiography and BNP tests. CardioStory is a rapid (~2 minutes), non-invasive tool that measures cardiac filling pressure, a key HF marker.

Objectives:

Primary: Assess CardioStory's diagnostic accuracy.

Secondary: Compare it with echocardiography and NT-proBNP, evaluate ease of use, and measure time to diagnosis.

Methods:

Adults (≥18) with acute dyspnea (<7 days) included; unstable or traumatic/allergic cases excluded.

CardioStory results will be compared to standard diagnostics.

Sample size: 850 patients over 12 months.

Outcome: If accurate, CardioStory could be a fast, practical diagnostic tool for emergency settings.

Enrollment: 650 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
