Spontaneous-Coronary-Artery-Dissection

What screening should I have after
a diagnosis of SCAD?
Abnormalities of the arteries throughout the body are common among SCAD patients,
and a condition known as fibromuscular dysplasia (FMD) has been seen in more than
60% of patients.
Fibromuscular dysplasia is a condition that weakens the artery walls making them
prone to tears or bulging. In FMD, patients can have abnormal blood vessels in many
parts of the body, including the heart, head and neck, and kidneys. It is recommended
that all patients with SCAD undergo blood vessel imaging from their head to pelvis to
screen for findings consistent with FMD at the time of diagnosis. This is done using noninvasive
imaging such as computed tomography angiography (CTA). If a patient has
FMD they should have a follow up at least once a year. Follow-up may include clinical
assessment, blood work and imaging. The timing and nature of imaging however, should
be individualized according to the severity of the disease and any symptoms.
There is no commercially available genetic screening test for SCAD, however this is an
active area of ongoing research.
Screening for connective tissue diseases including Marfan syndrome, Ehlers-Danlos
syndrome and Loey-Dietz syndrome, may be considered if you have other clinical signs or
symptoms consistent with these conditions.
Overall, we do not screen everyone for these conditions as they are rare. There is no
recommended screening for autoimmune or inflammatory disorders as there is no clear
association. Genetic counseling may be considered if there is a family history of inherited
arteriopathy such as Marfan syndrome or a history of aneurysms.
