Managing carotid plaque stability with statins and folic acid

Official title: A Prospective, Exploratory, Cohort Clinical Study Comparing the Effects of Oral Statins With or Without Folic Acid on Carotid Plaque Stability.

Run by Ruijin Hospital · NCT07680595 · Data updated 2026-11-12

This study tests whether adding folic acid to statin therapy helps stabilize carotid plaques in adults with plaque who have not had endarterectomy or stenting.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–75 with ultrasound- or CTA-confirmed carotid plaque and no prior carotid surgery or stenting, willing to participate for six months and comply with follow-up.

Probably not a fit

Patients with prior carotid interventions, severe organ impairment, malignancy, autoimmune or psychiatric conditions, or women who are pregnant or lactating may not benefit or participate.

What this trial studies

This prospective cohort study investigates the effect of folic acid on carotid plaque stability in patients receiving statin therapy. Participants are assigned to two groups: statin alone and statin plus folic acid, to explore potential benefits on plaque stability over six months. Eligibility includes adults 18–75 with ultrasound- or CTA-confirmed carotid plaque and no prior carotid interventions. The study uses imaging and blood tests to monitor changes in plaque characteristics and risk markers. Conducted in Shanghai, it aims to inform future randomized trials on folic acid supplementation in this patient population.

Why it matters

Potential benefit: If successful, adding folic acid to standard statin therapy could further reduce stroke risk by promoting plaque stability.

How similar studies have gone: Prior evidence suggests folic acid can reduce stroke risk in hypertensive patients, supporting exploration in plaque stability, though this specific approach is exploratory in plaque management.
