Many patients worry about having another SCAD. The latest data suggests around one in 10 patients will have a recurrence over a five to 10-year follow-up period. Which means 90% of patients do not have another SCAD. Studies also suggest that injuries to the heart after a recurrence are small so outcomes are usually good.
Some SCAD patients are concerned that if they have a SCAD in their 20s, 30s or 40s, they are at risk of having another one when they reach menopause age. There is no detailed statistical analysis on this, but SCAD experts say they haven’t seen any signals that people who have their first SCAD when they are younger are at more risk of a recurrence when they’re approaching menopause. The follow-up hasn’t been done for long enough to provide any solid information on this, however.
At the moment there is no clinical trial evidence to point to advice or preventative measures that may reduce the risk of having another SCAD. Blood pressure control is important, as is having strategies for managing stressful situations when they arise. Stress can't be avoided but learning techniques to help reduce its impact can be beneficial.

Symptoms & Diagnosis...
Recurrence
Around 10% of patients will have more than one SCAD, but research suggests the outcomes are good. Controlling blood pressure and stress is important
SCAD and Genetics
SCAD is not caused by a single gene, but research is starting to uncover genetic risk factors for SCAD
Clinic Referrals
Many patients find it helpful to be referred to a SCAD specialist to discuss treatment and further tests if they are needed
