Do Kawasaki disease patients without coronary artery abnormalities need a long-term follow-up? A myocardial single-photon emission computed tomography pilot study.

Objective: To determine the frequency and risk factors for long-term myocardial perfusion scintigraphy abnormalities in patients with Kawasaki disease (KD).

Methods: A cohort of patients with KD at least 3 years after disease onset and with persistent coronary artery aneurysms (CAA) (group 1) or without CAA (group 2) underwent stress-rest myocardial single-photon emission computed tomography (SPECT). Clinical and laboratory parameters at disease onset were considered to assess their predictive value for the development of myocardial perfusion abnormalities.
