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.
• Age ≥ 18 years
Recent onset dyspnea (less than 7 days)
Informed consent obtained
• Age inferior to 18 years,
Severe comorbidity, hemodynamic compromise or immediate need for mechanical ventilation were exclusion criteria.
Dyspnea clearly of traumatic or allergic origin
