Diagnostic Accuracy Of Seismocardiography for Coronary Artery Disease

Improvement of Diagnostic Accuracy of Seismocardiography and Gyrocardiography for Non-Invasive Coronary Artery Disease Diagnosis: A Comparison With Coronary Artery Calcium Computed Tomography, Coronary Computed Tomography Angiography, and Invasive Coronary Angiography

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.

Inclusion Criteria:

• Aged 18 years or older.
• Suspected CAD, based on clinical evaluation.
• Able to provide informed consent.

Exclusion Criteria:

• Pregnant or breastfeeding women.
• Presence of implanted cardiac devices (e.g., pacemakers, implantable cardioverter defibrillators) that may interfere with SCG/GCG signal acquisition.
• Severe arrhythmias that may affect signal interpretation.
• Inability to maintain required testing positions (supine and sitting).
• Medical conditions preventing informed consent (e.g., severe cognitive impairment).
