This is a prospective multi-center clinical trial. Using the CAD-det, acoustic and electrical cardiac data will be collected from participants with intermediate pretest probability of CAD who are referred to invasive coronary angiography (ICA). The CAD-det recording will be administered prior to the scheduled ICA procedure. The data collected by CAD-det will be processed using AusculSciences' Data Analysis Application (DAA) to produce a patient's indication for CAD.
The purpose of the study is to collect acoustic, ECG, and clinical data from consenting participants, so that AusculSciences can perform analysis on the sounds produced by the heart and determine the accuracy of the CAD-det System for detecting CAD.
