Who Is At Risk for Giant Cell Arteritis?
GCA affects mostly older people. It is rarely found in anyone younger than 50 years old and is more common around age 70. Women are twice as likely as men to have GCA.
People with northern European ancestry, particularly Scandinavian, are more likely to develop GCA. GCA is rare in Asians and African-Americans.
Polymyalgia rheumatica (PMR) is an inflammatory disorder involving pain and stiffness in the shoulder and usually the hip. People with PMR are also at increased risk for GCA. PMR can also occur with severe infections and the use of high doses of antibiotics.
