Objectives:

To describe the cardiac manifestations in the acute phase of patients with Kawasaki disease treated in a third level Children’s hospital in Mexico City, Mexico.

Methods:

A cross-sectional study was conducted in patients with a diagnosis of Kawasaki disease treated in this hospital from August 1995 to December 2016. Information included patient demographics, clinical features, treatment used, electrocardiographic findings, extra-coronary echocardiographic findings, and the development of coronary artery aneurysms in the acute phase of the disease.

Results:

The study included 508 cases of Kawasaki disease, with a mean age at diagnosis of

37.64 ± 35.56 months (range from 2 to 200 months). Almost two-thirds (65.4%) of the patients were male, with a male/female ratio of 1.88:1. Complete Kawasaki disease was diagnosed in 79.2% of cases. Almost all cases (92.4%) received intravenous immunoglobulin.

Twenty-eight patients (5.5%) developed arrhythmias, ST changes developed in 29 patients (5.6%), and 5 patients presented with ischaemic changes.

In the initial echocardiographic evaluation, 51 patients (9.9%) were diagnosed with myocar- ditis, 72 patients (14.0%) with pericarditis and 77 cases (15.0%) developed pericardial effusion. Coronary artery anomalies were detected in 169 cases (32.9%). 32 cases were diagnosed as giant coronary aneurysms. Four patients died from cardiac complications in the acute phase of the disease.

Conclusions:

There has been an increase in the diagnosis of Kawasaki disease in Mexico. They presented with more cardiac complications than reported in literature. An increased knowledge of Kawasaki disease is required in Mexico in order to establish the cardiac outcomes of this group of patients.
