Risk factors related to cardiovascular complications in children diagnosed with Kawasaki disease in Northwestern Mexico

Kawasaki disease (KD) is an acute systemic vasculitis of small and medium vessels, which occurs primarily in children; it manifests itself as a febrile syndrome coupled with vasculitis data and can cause coronary artery abnormalities in 25% of untreated patients. The objective of this study was to describe the clinical behavior and to identify risk factors for cardiovascular complications in pediatric patients with KD, in a second level hospital in Northwestern Mexico.Under a case series design, we studied pediatric patients with diagnosis of KD. We measured clinical variables, laboratory values and the presence of cardiac complications; the probability of risk was determined with odds ratio (OR) and the association with chi squared test.12 patients were included, and the female gender predominated; the mean age of presentation of KD was 2 years. The clinical presentation was complete in 100 % of the cases and patients also presented atypical manifestations. 50% of the patients studied had cardiovascular complications, the most common of which was coronary disease (33%). The variables male gender, age under 2 years and anemia reported OR of 5.5 and 10 to present cardiovascular complications.Cardiovascular complications of KD are frequent (more than 30%). Male gender, age under 2 years and anemia increase the probability of risk for the presence of cardiovascular complications.
