[Giant coronary aneurysms in infants with Kawasaki disease]. / Aneurismas coronarios gigantes en lactantes con enfermedad de Kawasaki.

INTRODUCTION: Kawasaki disease (KD) is an acute vasculitis of unknown origin and predominant in males. The long-term effects of the disease depend on whether there are coronary lesions, particularly aneurysms. The prognosis of patients with giant aneurysms is very poor due to their natural progression to coronary thrombosis or severe obstructive lesions. OBJECTIVES: A series of 8 cases is presented where the epidemiology and diagnostic methods are described. The treatment of the acute and long-term cardiovascular sequelae is also reviewed. METHODS: A descriptive analysis was conducted on patients admitted to the Paediatric Cardiology Unit of La Fe University Hospital (Valencia) with KD and a coronary lesion. RESULTS: More than one artery was involved in all patients. Although early diagnosis was established in only two cases, none of the patients had severe impairment of ventricular function during the acute phase. Treatment included intravenous gammaglobulin and acetylsalicylic acid at anti-inflammatory doses during the acute phase. A combination of dual antiplatelet therapy and corticosteroids was given in cases of coronary thrombosis. The silent aneurysms continue to persist. CONCLUSIONS: KD is the most common cause of acquired heart disease in children. The delay in diagnosis is associated with a greater likelihood of coronary lesions that could increase the risk of cardiovascular events in adulthood. Thus, this subgroup requires close clinical monitoring for a better control of cardiovascular risk factors over time.

Long-term prognosis of chronic kidney disease in non-ST elevation acute coronary syndrome treated with invasive strategy. / Pronóstico a largo plazo de la enfermedad renal crónica en el síndrome coronario agudo sin elevación del segmento ST tratado con estrategia invasiva.

BACKGROUND AND AIM: Patients with chronic kidney disease (CKD) have an increased risk of adverse cardiovascular outcomes after non-ST elevation acute coronary syndrome (NSTEACS). However, the information available on this specific population, is scarce. We evaluate the impact of CKD on long-term prognosis in patients with NSTEACS managed with invasive strategy. METHODS: We conduct a prospective registry of patients with NSTEACS and coronary angiography. CKD was defined as a glomerular filtration rate < 60ml/min/1,73m2. The composite primary end-point was cardiac death and non fatal cardiovascular readmission. We estimated the cumulative probability and hazard rate (HR) of combined primary end-point at 3-years according to the presence or absence of CKD. RESULTS: We included 248 p with mean age of 66.9 years, 25% women. CKD was present at baseline in 67 patients (27%). Patients with CKD were older (74.9 vs. 63.9 years; P<.0001) with more prevalence of hypertension (89.6 vs. 66.3%; P<.0001), diabetes (53.7 vs. 35.9%; P=.011), history of heart failure (13.4 vs. 3.9%; P=.006) and anemia (47.8 vs. 16%; P<.0001). No differences in the extent of coronary artery disease. CKD was associated with higher cumulative probability (49.3 vs. 28.2%; log-rank P=.001) and HR of the primary combined end-point (HR: 1.94; CI95%: 1.12-3.27; P=.012). CKD was an independent predictor of adverse cardiovascular outcomes at 3-years (HR: 1.66; CI95%: 1.05-2.61; P=.03). CONCLUSIONS: In NSTEACS patients treated with invasive strategie CKD is associated independently with an increased risk of adverse cardiovascular outcomes at 3years.

Aneurismas coronarios gigantes en lactantes con enfermedad de Kawasaki / Giant coronary aneurysms in infants with Kawasaki disease

Introducción: La enfermedad de Kawasaki (EK) es una vasculitis aguda de causa desconocida, predominante en el sexo masculino. Los efectos de la enfermedad a largo plazo dependen de la existencia de lesiones coronarias -aneurismas-, siendo el pronóstico de los pacientes con aneurismas gigantes sombrío, ya que en su evolución natural pueden presentar trombosis coronaria o lesiones obstructivas severas. Objetivos: Describimos las características de una serie de 8 pacientes lactantes con EK y severa afectación coronaria. Se describen la epidemiología y los métodos diagnósticos, y se revisa el tratamiento de la fase aguda, así como las secuelas cardiovasculares a largo plazo. Métodos: Se realizó un análisis descriptivo de pacientes ingresados en el Servicio de Cardiología Pediátrica del Hospital Universitario La Fe (Valencia) por EK con afectación coronaria. Resultados: En todos los casos se objetivó la afectación de más de una arteria. El diagnóstico se instauró precozmente en solo 2 casos, a pesar de ello, ningún paciente presentó deterioro grave de la función ventricular durante la fase aguda. El tratamiento incluyó gammaglobulina por vía intravenosa y ácido acetilsalicílico en dosis antiinflamatorias durante la fase aguda. En los casos de trombosis coronaria se asociaron doble antiagregación y corticoides. Las lesiones aneurismáticas silentes persisten hasta el momento actual. Conclusiones: La EK es la causa más común de enfermedad cardiaca adquirida en niños. El retraso en el diagnóstico se asocia a mayor frecuencia de lesiones coronarias, que podrían incrementar el riesgo de eventos cardiovasculares en la edad adulta, precisando este subgrupo un seguimiento clínico estrecho con control de los factores de riesgo cardiovascular a largo plazo (AU)

Pronóstico a largo plazo de la enfermedad renal crónica en el síndrome coronario agudo sin elevación del segmento ST tratado con estrategia invasiva / Long-term prognosis of chronic kidney disease in non-ST elevation acute coronary syndrome treated with invasive strategy

Introducción y objetivo: Los pacientes con enfermedad renal crónica (ERC) presentan mayor riesgo de eventos adversos cardiovasculares tras un síndrome coronario agudo sin elevación del segmento ST (SCASEST). Sin embargo, la información disponible en esta población específica es escasa. Evaluamos el efecto de la ERC en el pronóstico a largo plazo de pacientes con SCASEST tratados con estrategia invasiva. Métodos: Registro prospectivo de pacientes con SCASEST y coronariografía. Definimos ERC como una tasa de filtrado glomerular < 60ml/min/1,73m2. La variable de valoración final fue el combinado de muerte y reingreso cardiovasculares (nuevo síndrome coronario agudo, insuficiencia cardíaca e ictus no fatales). Estimamos la probabilidad acumulada, estratificada por ERC, y la relación entre esta y la tasa de riesgo del evento combinado a 3 años. Resultados: Incluimos a 248 pacientes, con media de edad de 66,9 años; el 25% eran mujeres. Los 67 casos (27%) con ERC fueron mayores (74,9 vs. 63,9 años; p < 0,0001) y con más prevalencia de hipertensión (89,6 vs. 66,3%; p < 0,0001), diabetes (53,7 vs. 35,9%; p = 0,01), historia de insuficiencia cardíaca (13,4 vs. 3,9%; p = 0,006) y anemia (47,8 vs. 16%; p < 0,0001). Sin diferencias en la extensión de la enfermedad coronaria. La ERC se asoció a mayor probabilidad (49,3 vs. 28,2%; log-rank p = 0,001) y tasa de riesgo del evento combinado (HR ajustada: 1,94; IC 95%: 1,12-3,27; p = 0,012). La ERC fue predictor independiente de eventos (HR: 1,66; IC 95%: 1,05-2,61; p = 0,03). Conclusiones: En pacientes con SCASEST tratados con estrategia invasiva, la ERC se asocia de manera independiente a mayor riesgo de eventos cardiovasculares a 3 años (AU)
