Outcomes of Kawasaki disease with giant coronary aneurysms: a single-centre study in southwest China
Published online by Cambridge University Press: 08 June 2020
Abstract
Giant coronary aneurysms are the most severe complications of Kawasaki disease. There are few reports of outcomes from China. Most previous studies were based only on absolute aneurysmal dimensions. The aim of the present study was to catalog the outcomes of Kawasaki disease with giant coronary aneurysms in southwest China based on absolute dimensions and the z-score adjusted for body surface area.
All patients diagnosed with giant coronary aneurysms (z-score ≥ 10 or absolute dimension ≥ 8 mm) between December, 2002 and December, 2018 were included. We retrospectively analysed patient characteristics and clinical data from 38 patients with giant coronary aneurysms. Over a median follow-up period of 30.5 months (range from 1.7 months to 22.3 years), including patients in chronic phase who had been diagnosed prior to 2002, eight patients had myocardial infarction, including two deaths and one patient with coronary artery bypass grafting. The 1-, 2-, and 5-year event-free rates were 0.63, 0.63, and 0.53 for thrombosis, respectively, and 0.86, 0.81, and 0.81 for major adverse cardiac events, respectively. The 1-, 2-, and 5-year regression-free rates were 0.94, 0.85, and 0.67, respectively. A total of 73.7% of patients remained active.
In the early stages of Kawasaki disease, patients with giant coronary aneurysms often experience major cardiovascular events; however, they are also likely to have normalisation of the coronary internal luminal diameter. With long-term anticoagulation, close cardiologic monitoring, and prompt thrombolytic therapy, most patients can achieve disease-free periods.
