The HeartAche project aims at early detection and prevention of coronary artery disease and detection of acute cardiac events. The project aims at developing a functioning cardiovascular monitoring ecosystem consisting of smart devices, add-on sensor modules for smart devices and a backend system. For end users, the visible part of the ecosystem would naturally be the smart device, which would give a comprehensible interpretation of measured data (i.e. vascular condition, cardiac motion, cardiac time intervals, and cardiovascular motion). The project aims to gather a comprehensive picture of the cardiovascular health condition by combining sonography, seismocardiography, electrocardiography and ballistocardiography signals to capture various facets of cardiovascular health
