ObjectiveTo investigate the postnatal risk of Kawasaki disease and coronary complications from a nationwide birth cohort in Taiwan, a country with the third-highest incidence of Kawasaki disease worldwide.Study designWe enrolled children born between 2000 and 2009 with complete postnatal medical care records for 2000-2014 in the Taiwan national database.ResultsOut of a total of 2â150â590 live births, we identified 6690 (62.6% boys) patients with Kawasaki disease. The onset was mostly (93.9%) within the first 5 years of life (median, 16 months; 38% during infancy), but was rare within the first 3 months of life. The overall cumulative incidence of Kawasaki disease by age 5 years was 2.78â° (3.33â° for boys and 2.17â° for girls; Pâ<â.001) and exhibited an increasing trend with birth year (from 2.28â° for 2000 to 3.67â° for 2009). The incidence ratio was 1.535 in boys and 1.055 in each increasing year. Kawasaki disease recurred more often in younger patients (cumulative incidence, 2.3% in infants vs 1.7% in children aged 1-4 years). Coronary complications occurred in 16.2% of the patients, including 4 cases of acute myocardial infarction (3 occuring during the acute stage and 1 occurring 5 years later). The probability of a major cardiac event (infarction, undergoing percutaneous coronary intervention or coronary artery bypass grafting, or death) by adolescence was 1.9%.ConclusionsThe postnatal risk of Kawasaki disease was 3â°-4â° and increased with every birth year. Patients with Kawasaki disease are at substantial risk for a major cardiac events during childhood.
