Participants in this arm will undergo seismocardiography (SCG) and gyrocardiography (GCG) testing using the CardioClin device, a non-invasive diagnostic tool designed to assess coronary artery disease (CAD). The device uses high-precision accelerometers and gyroscopic sensors to measure the mechanical vibrations of the heart.

All participants are already scheduled for standard diagnostic procedures such as coronary artery calcium computed tomography (CAC-CT), coronary computed tomography angiography (CCTA), or invasive coronary angiography (ICA). SCG/GCG testing will be performed before these standard procedures, with measurements taken in both supine and sitting positions.

The goal is to compare the diagnostic accuracy of CardioClin SCG/GCG recordings against traditional imaging methods to assess its potential as a non-invasive alternative for CAD detection.

This intervention involves the use of Seismocardiography (SCG) and Gyrocardiography (GCG) Diagnostic Testing, a non-invasive technique that records mechanical vibrations of the chest caused by heart activity using high-precision accelerometers and gyroscopes. Unlike traditional imaging techniques such as coronary artery calcium computed tomography (CAC-CT), coronary computed tomography angiography (CCTA), and invasive coronary angiography (ICA), this method does not require radiation exposure (unlike CAC-CT and CCTA), is completely non-invasive and does not require contrast agents (unlike ICA), and provides real-time cardiac mechanical activity measurements rather than anatomical imaging.
