Overview
Brief Summary
In this study the ability of smartphone sensors (accelerometer and gyroscope) to identify patients with heart failure will be studied.
Detailed Description
Heart Failure (HF) is a condition where heart is unable to maintain adequate volume of blood in circulation corresponding to prevailing physiological demand. Gyrocardiography is a technique that utilizes micro electromechanical sensors (MEMS), accelerometer and gyroscope, to detect vibrations and rotation of thorax caused by cardiac motion. The main purpose of this study is to test the ability of an app of a smartphone with embedded motion sensors, positioned on the chest which measures the movements and function of the heart, to identify patients with different types of heart failure and their characteristics, as compared with clinical diagnosis. Echocardiography will also be used to confirm changes in cardiac cardiac mechanics including strain, cardiac torsion, diastolic filling characteristics.

Outcomes
Primary Outcomes
HF specific motion sensor characteristics validation against echocardiography and other clinical features
Time Frame: From the hospital admission to study closure visit, on average 15 weeks
The study aims to validate HF specific characteristics obtained with accelerometer (m/s2) and gyroscope (degree/s) against the current gold standard, detailed echocardiography examination in individuals already diagnosed with HF. Data of anonymised subjects without diagnosed or suspected HF will be used as controls to study the detection of HF.
Secondary Outcomes
- HF decompensation specific motion sensor characteristics validation(14 weeks)
