A frequency power measure is determined () based on the signal strength of a first frequency window of a period in the diastole, an amplitude of the fourth heart sound is determined () based on the plurality of heart sounds and the plurality of segments, and an indication of a heart rate variability is determined () based on the plurality of heart sounds. The indication of the risk for coronary artery disease is then determined () based on the frequency power measure, the amplitude of the fourth heart sound, and the indication of the heart rate variability.
