Genetic causes of spontaneous coronary artery dissection
Official title: Genetic Investigations in Spontaneous Coronary Artery Dissection (SCAD)
Run by Mayo Clinic · NCT01427179 · Data updated 2026-11-12
This project will test whether inherited or new gene changes cause spontaneous coronary artery dissection in adults with SCAD and their biological relatives.

Is this trial a fit for you?
✓Likely a good fit
Adults with one or more confirmed episodes of SCAD who can give informed consent, and their biological parents or relatives with fibromuscular dysplasia, arterial aneurysm, or arterial dissection willing to provide samples.
✕Probably not a fit
People without angiographic confirmation of SCAD or those unable to provide informed consent or a blood/saliva sample are unlikely to benefit from participation.

What this trial studies
The study creates a genomic DNA and plasma biobank from adults with angiographically confirmed SCAD and from their biological parents and affected relatives. Researchers will search for inherited and de novo mutations and look for common genetic variants that increase SCAD risk using genomic analyses. Participants are identified both retrospectively and prospectively, with diagnosis confirmed by coronary angiogram review before consent and sample collection. Long-term goals include defining molecular mechanisms and developing biomarkers to improve prediction and prevention of SCAD.
Why it matters
Potential benefit: If successful, this work could enable genetic tests and biomarkers to identify people at higher risk for SCAD and support family screening and prevention strategies.
How similar studies have gone: Some prior genetic and genome-wide studies have found risk loci suggesting a genetic contribution to SCAD, but comprehensive inherited and de novo mutation analysis remains relatively novel.
