The disorder affects about 1% of people with high blood pressure, including both children and adults. It is more common in younger adults, especially African American men. It also occurs in women with toxemia of pregnancy, and persons with kidney disorders or collagen vascular disorders.

You are at high risk for malignant hypertension if you have had kidney failure or renal hypertension caused by renal artery stenosis.
