Abstract

Patients with different forms of systemic vasculitis experience long-term morbidity and mortality caused by cardiovascular disease due to premature atherosclerosis. Epidemiologic reports of patients with GCA suggest that long-term mortality in this disease is not increased compared with the general population of the same age. The risk of a stroke, however, in particular in the vertebrobasilar territory, is increased. In addition, the occurrence of aortic aneurysmal disease and aortic dissection is also clearly increased in GCA. Mortality due to ischaemic heart disease, however, is not increased. In Takayasu arteritis accelerated atherosclerosis has been clearly documented both clinically and in autopsy reports. Atherosclerotic plaques in the carotid artery may be present in the carotid arteries especially in patients with a documented history of arteritis involving the carotid artery. It is controversial whether Kawasaki disease is associated with accelerated atherosclerosis. Young adults with a history of Kawasaki disease may have abnormal brachial artery reactivity, increased carotid IMT values and increased arterial stiffness. At autopsy examinations of KD patients, however, no significant atherosclerotic lesions are detected and carotid IMT measurements were found to be clearly different from those in young adults with familiar hypercholesterolaemia, suggesting that the remodeling process in KD is different from atherosclerosis. In ANCA-associated vasculitis (AAV), an increased mortality as a consequence of cardiovascular disease is well-documented. In these patients the relative risk for coronary heart disease is two- to fourfold that in control subjects. In addition, a similar relative risk has been found for stroke. Diabetes, hypertension, dyslipidemia, abdominal obesity (metabolic syndrome), impaired renal function, persistent proteinuria and increased production of C-reactive protein are common risk factors for premature atherosclerosis in patients with systemic vasculitis. Furthermore, cholesterol and its modifications play a pivotal role in the pathogenesis of accelerated atherosclerosis in vasculitis. The (preventive) therapy for accelerated atherosclerosis in systemic vasculitis is based on an aggressive approach against inflammation and against risk factors of premature atherosclerosis such as smoking, inactivity, obesity and unhealthy diet. In addition, patients should be treated with angiotensin-converting enzyme inhibitors and/or angiotensin receptor-1 blockers for hypertension and statins for dyslipidemia. Finally, low dose acetylsalicylic acid should be prescribed in patients with large vessel vasculitis, i.e., both in GCA and TA, who do not have contraindications for ASA.
