Clinical Trial Summary

The study will test the ability a novel wearable sensor based on a smartphone app (Precordior CardioSignal app) in combination with a sensor device (Suunto Movesense sensor) to non-invasively measure cardiac motion and function.

Description:

Heart Failure (HF) is a syndrome where the heart is unable to pump or fill adequately to meet the circulatory needs of the body. The main purpose of this study is to test the ability a novel wearable sensor based on a smartphone app (Precordior CardioSignal app) in combination with a sensor device (Suunto Movesense sensor) to non-invasively measure cardiac motion and function. The phone and sensor are positioned on the chest and echocardiography is used as a gold standard to assess cardiac mechanics including myocardial strain, cardiac torsion, diastolic filling characteristics, hemodynamics including pressure estimates and stroke volume.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Heart failure detection	Test the ability of the Precordior sensor to detect heart failure with reduced ejection fraction, heart failure with preserved ejection fraction and pulmonary hypertension compared to control participants. An additional comparison will be made to individuals without signs, diagnosed, or suspected HF who will be undergoing CCTA due to suspected CAD.	Baseline to Day 2
Secondary	Detection of differences in myocardial mechanics between admission and discharge	The ability of the Precordior sensor to detect differences in myocardial mechanics as defined my myocardial longitudinal strain, hemodynamics and torsion analysis from admission and discharge.	up to 2 weeks (during admission) and 2 to 14 weeks (during follow-up visit).
