Improving prediction of coronary artery disease using arterial stiffness measurements

Pulse Wave Velocity and Machine Learning for Prediction of Coronary Artery Disease by Coronary CT Angiography - the Heart Waves Study

Observational Danderyd Hospital · NCT06734247

This study is testing if using a new method that measures how stiff your arteries are can help doctors better predict coronary artery disease in patients who might have it.

What this trial studies

This observational study aims to evaluate how device-estimated pulse wave velocity and machine learning techniques can enhance the prediction of symptomatic coronary artery disease in stable patients. It focuses on patients with suspected coronary artery disease who are undergoing coronary computer tomography angiography (CCTA). The study will compare traditional pre-test probability assessments with a new risk factor-weighted clinical likelihood method to improve risk estimation. By integrating non-invasive measurements of arterial stiffness, the study seeks to refine the decision-making process for further investigations.

Who should consider this trial

Good fit: Ideal candidates are stable patients aged 30 to 70 years with suspected symptomatic coronary artery disease who are undergoing CCTA.

Not a fit: Patients with known coronary artery disease or significant cardiac or pulmonary conditions that could explain their symptoms may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate predictions of coronary artery disease, potentially reducing unnecessary invasive procedures for patients.

How similar studies have performed: Other studies have shown promise in using machine learning and non-invasive measures for cardiovascular risk assessment, indicating a potential for success in this approach.
