Final answer:
Polymyalgia rheumatica (PMR) is the disease most closely associated with a high risk of giant cell arteritis, a condition that causes inflammation of arterial walls.
Step-by-step explanation:
Which of the following diseases is associated with a high risk of giant cell arteritis? Among the conditions listed, Polymyalgia rheumatica (PMR) is closely associated with giant cell arteritis. PMR is an inflammatory disorder that causes muscle pain and stiffness, mostly in the shoulders and hips, and can often co-occur with giant cell arteritis, an inflammation of the lining of the arteries. In clinical practice, patients with PMR are monitored for symptoms of giant cell arteritis, which include headache, jaw claudication, and visual disturbances, due to the significant risk of comorbidity.
