What this trial studies

This observational clinical study aims to validate the CLAiR AI software's ability to identify elevated atherosclerotic cardiovascular disease (ASCVD) risk by analyzing retinal images from two different camera models. Participants aged 40-75 will have their retinal images and clinical biomarker data collected to compare the CLAiR algorithm's predictions against the established PCE risk score. The study seeks to determine the sensitivity and specificity of the CLAiR model in classifying individuals as having elevated or non-elevated ASCVD risk over the next decade.

Who should consider this trial

Good fit: Ideal candidates are adults aged 40-75 who are willing to participate and provide informed consent.

Not a fit: Patients with a known history of atherosclerotic cardiovascular disease or those currently on cholesterol-lowering medications will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a non-invasive method for early identification of individuals at high risk for cardiovascular diseases.

How similar studies have performed: Other studies have shown promise in using AI for cardiovascular risk assessment, but this specific approach is novel.
