Acoustic detection of coronary artery disease

Coronary artery disease, CAD, is the result of accumulation of fat, cholesterol and calcium into plagues within the walls of the coronary arteries supplying the heart muscle with oxygen and nutrients. One in four of all deaths by CAD is sudden and asymptomatic and thus occurs without prior warning symptoms.
A new technology for detecting CAD at an early stage was conceived by researchers at Aalborg University: Postdoc Samuel Schmidt, Assistant Professor Claus Graff and Associate Professor Johannes Struijk from the Medical Informatics Group of this department, and was further developed together with researchers from Acoustics and the company Coloplast. The system, detecting murmur in the heart sound, is based on advanced microphones and algorithms as the murmur only makes up 1/1000 of the sound of the heart beat.
The technology was put into production as the CADScor System by the company Acarix, which has just raised a venture capital of 27 mill. DKK for further development and marketing.

Dept. of Health Science and Technology (Institut for Medicin og Sundhedsteknologi)

The mission of the department is to establish and disseminate technological and medical competencies within the health scene “from cell to system”.

The department is the largest medical technology environment in Denmark – measured in researchers, publications, students, and turnover.
