Brief Summary:

Measuring cardiac contractility is commonly realized with gold standard echocardiography or MRI. Portable devices to measure this contractility are not available as for rhythm and electric function assessment. The new Kinocardiography technology could provide a non invasive and portable tool to measure contractility.

This device records the electric and mechanic function of the heart. With electrodes and adequate electronics, ECG is recorded. 6 degrees of freedom accelerometers are also included in the device to measure the micro accelerations of the body at the body surface when the device is placed on the skin. Using physics principles and adequate calibration, those accelerations allow the investigators to calculate parameters such as kinetics energies related to heart contractility. Kinocardiography is a non invasive and portable technology.

Arm Intervention/treatment
Experimental: HFrEF: Heart failure - reduced ejection fraction
Patients with heart failure and reduced ejection fraction (around 35%).
Device: Kinocardiography

This device records the electric and mechanic function of the heart. With electrodes and adequate electronics, ECG is recorded. 6 degrees of freedom accelerometers are also included in the device to measure the micro accelerations of the body at the body surface when the device is placed on the skin. Using physics principles and adequate calibration, those accelerations allow us to calculate parameters such as kinetics energies related to heart contractility.

During a standard appointment for a patient suffering from a cardiac condition with/without heart failure, the cardiologist will monitor the heart of the patient with the Kino device (examination lasting a few minutes with the patient lying down on a bed). Data will be matched between the control group and the experimental group.


Active Comparator: Control
Patients with a cardiac condition but a normal ejection fraction (>45%), without heart failure. The patients from the HFrEF group will be matched with patients from the control group for sex, age, BMI and cardiovascular treatment.

Primary Outcome Measures :
  1. Total heart kinetic energy [ Time Frame: 1 hour ]
    Computed according to the micro accelerations of the body at the body surface. The hypothesis is that the investigators will observe a lower total heart kinetic energy for the HFrEF group in comparison to paired control patient group.


Secondary Outcome Measures :
  1. Ratio of torsional kinetic energy over total kinetic energy [ Time Frame: 1 hour ]
    Computed according to the micro accelerations of the body at the body surface. The hypothesis is that the investigators will observe a lower ratio of torsional kinetic energy over total kinetic energy for HFrEF group in comparison to paired control group.
