ABSTRACT
RESUMEN Introducción: Las enfermedades cardiovasculares de la infancia constituyen un grupo heterogéneo de afecciones congénitas y adquiridas que representan una causa importante de morbilidad y mortalidad pediátricas. Objetivo: Describir clínica y epidemiológicamente a los pacientes pediátricos fallecidos por enfermedades cardiovasculares entre los años 2005 y 2017. Métodos: Estudio descriptivo transversal retrospectivo en los 117 pacientes pediátricos fallecidos con diagnóstico de enfermedades cardiovasculares en la provincia de Villa Clara, entre los años 2005 y 2017, con predominio del análisis documental como método de investigación. Resultados: Se obtuvo una tasa de mortalidad de 1,6 por cada 1000 nacidos vivos con tendencia a disminuir en el tiempo, con predominio de los fallecidos con piel blanca (70,09 %), y sin diferencias en cuanto al sexo. Fueron más frecuentes las cardiopatías congénitas (75,21 %) como coartación aórtica y transposición de grandes vasos. Entre las cardiopatías adquiridas fue la miocarditis la más frecuente (79,30 %). Se diagnosticaron en la primera semana de vida 48,70 % de los pacientes y recibieron tratamiento médico 63,25 % de los pacientes. Las causas de muerte más frecuentes fueron la propia cardiopatía congénita de base y la disfunción multiorgánica por sepsis en el grupo de las congénitas y en las adquiridas el shock cardiogénico. Conclusiones: Predominaron las cardiopatías congénitas fundamentalmente la coartación aórtica. La mayoría de los pacientes recibieron solo tratamiento médico y las principales causas directas de muerte fueron la propia cardiopatía congénita y la disfunción multiorgánica.
ABSTRACT Introduction: Children cardiovascular diseases constitute a heterogeneous group of congenital and acquired conditions that represent an important cause of pediatric morbidity and mortality. Objective: Describe clinically and epidemiologically pediatric patients who died of cardiovascular diseases between 2005 and 2017. Methods: A retrospective cross-sectional descriptive study was conducted in the 117 pediatric patients who died with a diagnosis of cardiovascular diseases in the Villa Clara province, between 2005 and 2017, with a predominance of documentary analysis as a research method. Results: A mortality rate of 1.6 per 1000 live births was obtained, with a tendency to decrease over time, with a predominance of those who died with white skin (70.09%), and without differences in sex. Congenital heart disease (75.21%) was more frequent, such as aortic coarctation and transposition of large vessels. Among the acquired heart diseases, myocarditis was the most frequent (79.30%). 48.70% of patients were diagnosed in the first week of life and 63.25% of patients received medical treatment. The most frequent causes of death were congenital heart disease itself and multi-organ dysfunction due to sepsis in the congenital group and in those acquired cardiogenic shock. Conclusions: Congenital heart disease predominated, mainly aortic coarctation. Most patients received only medical treatment and the main direct causes of death were congenital heart disease itself and multi-organ dysfunction.
ABSTRACT
It is unclear to which extent the higher mortality associated with hypertension in the coronavirus disease (COVID-19) is due to its increased prevalence among older patients or to specific mechanisms. Cross-sectional, observational, retrospective multicenter study, analyzing 12226 patients who required hospital admission in 150 Spanish centers included in the nationwide SEMI-COVID-19 Network. We compared the clinical characteristics of survivors versus non-survivors. The mean age of the study population was 67.5 ± 16.1 years, 42.6% were women. Overall, 2630 (21.5%) subjects died. The most common comorbidity was hypertension (50.9%) followed by diabetes (19.1%), and atrial fibrillation (11.2%). Multivariate analysis showed that after adjusting for gender (males, OR: 1.5, p = 0.0001), age tertiles (second and third tertiles, OR: 2.0 and 4.7, p = 0.0001), and Charlson Comorbidity Index scores (second and third tertiles, OR: 4.7 and 8.1, p = 0.0001), hypertension was significantly predictive of all-cause mortality when this comorbidity was treated with angiotensin-converting enzyme inhibitors (ACEIs) (OR: 1.6, p = 0.002) or other than renin-angiotensin-aldosterone blockers (OR: 1.3, p = 0.001) or angiotensin II receptor blockers (ARBs) (OR: 1.2, p = 0.035). The preexisting condition of hypertension had an independent prognostic value for all-cause mortality in patients with COVID-19 who required hospitalization. ARBs showed a lower risk of lethality in hypertensive patients than other antihypertensive drugs.
