Further study details as provided by Coloplast A/S:

Primary Outcome Measures:
  • Sensitivity versus 1-specificity as a function of cut-off values on the 'Cardiac Noise Marker' scale here under Sensitivity by suitable cut-off value on the 'Cardiac Noise Marker' scale and Specificity with same cut-off value. [ Time Frame: The first testday ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Observed differences in distribution of 'Cardiac Noise Marker' within three sub-groups. [ Time Frame: The first testday ] [ Designated as safety issue: No ]

Estimated Enrollment: 350

Groups/Cohorts Assigned Interventions
Patients referred to CAG. Device: Acoustic recording.
Aquiring acoustic signals from heart patients.
Other Name: Acarix CAD device.

Detailed Description:

Acoustic information from the heart is obtained from patients suffering from Coronary Artery Disease. The acoustic signals are evaluated as indicators for CAD.
