Incidence and predictors of large-artery complication (aortic aneurysm, aortic dissection, and/or large-artery stenosis) in patients with giant cell arteritis: a population-based study over 50 years.

OBJECTIVE: To determine the incidence and predictors of large-artery complication (aortic aneurysm, aortic dissection, and/or large-artery stenosis) in patients with giant cell arteritis (GCA). METHODS: The cohort of all residents of Olmsted County, Minnesota, in whom GCA was diagnosed between January 1, 1950, and December 31, 1999, was followed up. The incidence of aortic aneurysm, aortic dissection, and large-artery stenosis was determined. Possible predictors and correlates of large-artery complication were assessed. RESULTS: Forty-six incident cases of large-artery complication (representing 27% of the 168 patients in the cohort) were identified. These included 30 incident cases (18%) of aortic aneurysm and/or aortic dissection. Of these cases, 18 (11%) involved the thoracic aorta, with aortic dissection developing in 9 (5%). There were 21 incident cases (13%) of large-artery stenosis. Fifteen patients (9%) had incident cervical artery stenosis, and 6 (4%) had incident subclavian/axillary/brachial artery stenosis. One patient (0.6%) had incident iliac/femoral artery stenosis attributable to GCA. Hyperlipidemia and coronary artery disease were associated with aortic aneurysm and/or dissection (P < 0.05 for both). Cranial symptoms (headache, scalp tenderness, abnormal temporal arteries) were negatively associated with large-artery stenosis (hazard ratio [HR] 0.10 [95% confidence interval (95% CI) 0.03-0.35, P < 0.0005]), as was a higher erythrocyte sedimentation rate (HR 0.80 [95% CI 0.67-0.95, P < 0.05] per 10 mm/hour). CONCLUSION: Large-artery complication is common in GCA. Increased awareness of large-artery complication in GCA, particularly early-occurring aortic dissection, may decrease associated mortality.

Mortality of large-artery complication (aortic aneurysm, aortic dissection, and/or large-artery stenosis) in patients with giant cell arteritis: a population-based study over 50 years.

OBJECTIVE: To determine the mortality of giant cell arteritis (GCA) with large-artery complication compared with that of GCA without large-artery complication. METHODS: An inception cohort of 168 residents of Olmsted County, Minnesota, in whom GCA was diagnosed between January 1, 1950, and December 31, 1999, was followed up. Mortality in patients with incident large-artery complication (aortic aneurysm, aortic dissection, and large-artery stenosis) was determined and compared with that in patients in whom large-artery complication did not develop. RESULTS: No difference in survival was observed between the total group of patients with any type of large-artery complication and patients without large-artery complication or the general population. However, mortality was markedly increased in the 9 patients in whom thoracic aortic dissection developed (median survival 1.1 years [interquartile range 0.2-7.8 years]) compared with that in all other patients with GCA (P < 0.001). No difference in survival was observed between the group of patients with either aortic aneurysm and/or dissection (thoracic and/or abdominal aorta) and the group with GCA without large-artery complication. Survival of patients with GCA and large-artery stenosis was not different from that of patients with GCA without large-artery complication. CONCLUSION: Thoracic aortic dissection in GCA is associated with markedly increased mortality. Overall, mortality in the whole group of patients with GCA with large-artery complication was similar to that in patients with GCA without large-artery complication.
