Recent research has identified genetic variants that confer a higher risk of having a SCAD, but it is not caused by a single gene in the same way hereditary diseases are. These genetic variants can be likened to the 'hand of cards' we're dealt at birth (our genetic make-up) – each person will have a different combination of many common variants and it is this combination that can increase the risk of having a SCAD.

SCAD and Genetics

Children of SCAD patients will have a different combination, which means the risk of them having a SCAD is very low. It is not currently recommended that other family members have genetic screening unless the SCAD patient has symptoms of other conditions that are hereditary.

Some of the genetic variants are related to the integrity of tissues within the arterial wall and to blood clotting. And there seems to be a genetic risk factor for higher blood pressure in many SCAD patients, so controlling blood pressure is important.
