RESUMO
Background: Currently, there is a spreading worldwide tendency to characterize health issues and to propose alternative solutions via the creation of computerized databases. The aim of this study was to present the results in a computerized database of pediatric cardiac surgeries developed under the auspices of the Mexican Association of Specialists in Congenital Heart Diseases (Asociación Mexicana de Especialistas en Cardiopatías Congénitas A.C) and coordinated by the collegiate group of Pediatric Cardiology and Surgery as petitioned by the National Institutes of Health and High Specialty Hospitals Coordinating Commission. Methods: We analyzed all cases registered in the database during a 1-year observation period (August 1, 2011 to July 31, 2012) by all major Health Ministry-dependent institutes and hospitals offering surgical services related to pediatric cardiopathies to the non-insured population. Results: Seven institutions participated voluntarily in completing the database. During the analyzed period, 943 surgeries in 880 patients with 7% reoperations (n = 63) were registered. Thirty-eight percent of the surgeries were performed in children <1 year of age. The five most common cardiopathies were patent ductus arteriosus (n = 96), ventricular septal defect (n = 86), tetralogy of Fallot (n = 72), atrial septal defect (n = 68), and aortic coarctation (n = 54). Ninety percent of surgeries were elective and extracorporeal circulation was used in 62% of surgeries. Global mortality rate was 7.5% with the following distribution in the RACHS-1 score categories: 1 (n = 4, 2%), 2 (n = 19, 6%), 3 (n = 22, 8%), 4 (n = 12, 19%), 5 (n = 1, 25%), 6 (n = 6, 44%), and non-classifiable (n = 2, 9%). Conclusions: This analysis provides a representative view of the surgical practices in cardiovascular diseases in the pediatric population at the national non-insured population level. However, incorporating other health institutions to the national registry database will render a more accurate panorama of the national reality in surgical practices in the population <18 years of age.
RESUMO
En la insuficiencia cardíaca la utilidad de los agentes vasodilatadores depende de su habilidad para disminuir la postcarga ventricular izquierda; este efecto no necesariamente persiste con el tratamiento prolongado. El presente estudio reporta la respuesta clínica de 16 pacientes con insuficiencia cardíaca congestiva. El estudio fue doble ciego con enalapril y/o placebo durante 24 semanas. Los diagnósticos fueron cardiomiopatía dilatada en seis, cardiopatía reumática en cinco, isquémica en cuatro e hipertensiva en uno. Dos pacientes en tratamiento con enalapril fallecieron de causa no cardíaca y una fue retirada del estudio por embarazo. En aquellos pacientes tratados con enalapril la clase funcional (HYHA) mejoró de 2.9/08 à 1.1/0.4 (p<0.001), y la capacidad de esfuerzo se incrementó de 545/171 a 888/160 segundos (p<0.01). La función sistólica ventricular izquierda evaluada por ecocardiograma y ventriculograma con Tc 99m, cardiomegalia radiológica y diámetros del ventrículo izquierdo en el ecocardiograma no mostraron cambios significativos. No existieron efectos colaterales, ni anormalidades de laboratorio. Se concluye que en este estudio, el enalapril produjo mejoría clínica sostenida en pacientes con insuficiencia cardíaca y fue bien tolerado durante el tratamiento prolongado
