Brief summary

This study aims to evaluate a new, non-invasive method for detecting coronary artery disease (CAD) using seismocardiography (SCG) and gyrocardiography (GCG). These techniques measure small vibrations on the chest caused by the heartbeat using highly sensitive sensors. The goal is to determine whether this method, using the CardioClin device, can accurately detect CAD compared to standard tests like coronary calcium scans (CAC-CT), CT angiography (CCTA), and invasive coronary angiography (ICA). Patients who are already scheduled for one of these standard tests will also undergo SCG/GCG testing. The study will compare results to see if the new method provides a reliable, cost-effective, and radiation-free alternative for diagnosing CAD. This research could help improve early detection of heart disease without the need for invasive procedures.

Interventions

DEVICESeismocardiography (SCG) and Gyrocardiography (GCG) Diagnostic Testing

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.
