Context: Patients with rheumatoid arthritis (RA) have a high prevalence of cardiovascular disease. Inflammation in RA could be associated with myocardial microvascular disease and in turn result in cardiac dysfunction.
Methods and Results: In order to assess the prevalence of myocardial microvascular dysfunction in patients with RA, the authors prospectively performed rest/vasodilator stress N-13 ammonia positron emission tomography (PET) and echocardiography in 76 patients with RA, but no clinical cardiovascular disease. Data on non-RA controls was retrospectively collected from patients (asymptomatic, n = 14 and symptomatic, n = 34)...
