Hipertensión pulmonar tromboembólica crónica en España: una década de cambio / Chronic thromboembolic pulmonary hypertension in Spain: a decade of change

Introducción y objetivos El tratamiento de la hipertensión pulmonar tromboembólica crónica (HTPTEC) ha evolucionado en la última década. Sin embargo, apenas se dispone de información sobre el impacto de estos logros en la población general a escala nacional. Este estudio se diseñó para describir las características de los pacientes con HTPTEC en España en la última década. Métodos Se recogieron prospectivamente datos epidemiológicos, clínicos y pronósticos de los pacientes con HTPTEC consecutivos incluidos en el registro español REHAP desde el 1 de enero de 2007 al 31 de diciembre de 2018. Se evaluaron las diferencias entre diferentes periodos de tiempo, estableciendo 2013 como fecha de referencia para el análisis. Se calculó la puntuación de propensión para la intervención mediante un modelo multivariable de regresión logística. Resultados Se incluyó a 1.019 pacientes; se remitió a 659 (64,4%) a un centro nacional de referencia en HTPTEC. Del total, se seleccionó a 350 (34,3%) para cirugía y a 97 (9,6%) para tratamiento percutáneo. Entre los pacientes diagnosticados entre 2007 y 2012 hubo más frecuencia de muerte que entre los diagnosticados de 2013 en adelante (HR=1,83; IC95%, 1,07-3,15; p=0,027). En el grupo de pacientes ajustado por el modelo de puntuación de propensión, las resistencias vasculares pulmonares basales y la distancia recorrida en el test de 6 min de marcha también fueron determinantes del pronóstico (respectivamente, HR=1,24; IC95%, 1,15-1,33; p=0,011, y HR=0,93; IC95%, 0,90-0,97; p=0,001). Las tasas de supervivencia de los pacientes que se sometieron a un procedimiento intervencionista (trombendarterectomía pulmonar o angioplastia con balón de arterias pulmonares) resultaron llamativamente altas. Conclusiones Durante la última década, el diagnóstico y el pronóstico de la HTPTEC han mejorado de manera considerable. La gravedad de la enfermedad al diagnóstico determinó el perfil de riesgo. ...

Introduction and objectives Chronic thromboembolic pulmonary hypertension (CTEPH) treatment has evolved in the last decade. However, there is scarce information on the long-term impact of this progress in a real-life population at a national level. This study was designed to analyze the characteristics of CTEPH patients in Spain over the last decade. Methods We prospectively collected epidemiological, clinical, and prognostic data from CTEPH patients consecutively included in the Spanish REHAP registry from January 1, 2007, to December 31, 2018. We evaluated differences over time, establishing 2013 as the reference date for analysis. Propensity scores for interventional treatment were calculated using a multivariable logistic regression model. Results A total of 1019 patients were included; 659 (64.4%) were evaluated at a national CTEPH center. Overall, 350 patients (34.3%) were selected for surgery and 97 (9.6%) for percutaneous treatment. Patients diagnosed between 2007 and 2012 died more frequently than those diagnosed from 2013 onward (HR, 1.83; 95%CI, 1.07-3.15; P=.027). Within the subgroup of patients adjusted by propensity score, baseline pulmonary vascular resistance and the 6-minute walk test distance also determined the outcome (HR, 1.24; 95%CI, 1.15-1.33; P=.011; and HR, 0.93; 95%CI, 0.90-0.97; P=.001, respectively). High survival rates were found in patients who underwent an invasive procedure (pulmonary endarterectomy or balloon pulmonary angioplasty). Conclusions CTEPH diagnosis and prognosis have consistently improved in the last decade. Baseline disease severity determines the risk profile. Patients who undergo pulmonary endarterectomy or balloon pulmonary angioplasty have better outcomes. (AU)

Mortalidad hospitalaria y reingresos por insuficiencia cardiaca en España. Un estudio de los episodios índice y los reingresos por causas cardiacas a los 30 días y al año / In-hospital mortality and readmissions for heart failure in Spain. A study of index episodes and 30-day and 1-year cardiac readmissions

Introducción y objetivos: La insuficiencia cardiaca (IC) es un problema de salud significativo en España. Sin embargo, se dispone de pocos datos epidemiológicos sobre los ingresos hospitalarios por IC y el impacto de las características de los centros sanitarios en el pronóstico de estos pacientes. El objetivo de este estudio es identificar los factores relacionados con la mortalidad hospitalaria y los reingresos, así como analizar la relación entre las características de los hospitales y el pronóstico. Métodos: Estudio retrospectivo en el que se analizaron las altas con IC como diagnóstico principal en el Sistema Nacional de Salud español durante 2012, a través del Conjunto Mínimo Básico de Datos. Mediante análisis multivariable se obtuvieron la mortalidad ajustada por riesgo en el episodio índice y los reingresos por enfermedad cardiovascular a los 30 días y al año. Resultados: Se incluyó a 77.652 pacientes con IC, con una media de edad de 79,2+/-9,9 años. El 55,3% eran mujeres. La mortalidad hospitalaria durante el evento índice fue del 9,2% y se incrementó hasta el 14,5% a lo largo del año de seguimiento. La tasa de reingresos por enfermedad cardiaca fue del 32,6%. La mortalidad ajustada a 1 año resultó inferior entre los hospitales con mayor volumen de altas por IC (del 10,3+/-5,6% al 8,6+/-2,2%; p <0,001). La tasa de reingresos al año fue superior entre los hospitales de mayor volumen (del 32,3+/-3,7% al 33,7+/-4,5%; p=0,006). La existencia de un servicio de cardiología estructurado en el hospital se asoció con mejor pronóstico (mortalidad hospitalaria ajustada, el 9,9+/-3,8% frente al 9,2+/-2,4%; p <0,001). Conclusiones: El mayor volumen de altas por IC y la existencia de un servicio de cardiología en el hospital se asociaron con menor mortalidad hospitalaria

Introduction and objectives: Heart failure (HF) is a major health care problem in Spain. Epidemiological data from hospitalized patients are scarce and the association between hospital characteristics and patient outcomes is largely unknown. The aim of this study was to identify the factors associated with in-hospital mortality and readmissions and to analyze the relationship between hospital characteristics and outcomes. Methods: A retrospective analysis of discharges with HF as the principal diagnosis at hospitals of the Spanish National Health System in 2012 was performed using the Minimum Basic Data Set. We calculated risk-standardized mortality rates (RSMR) at the index episode and risk-standardized cardiac diseases readmissions rates (RSRR) and in-hospital mortality at 30 days and 1 year after discharge by using a multivariate mixed model. Results: We included 77 652 HF patients. Mean age was 79.2+/-9.9 years and 55.3% were women. In-hospital mortality during the index episode was 9.2%, rising to 14.5% throughout the year of follow-up. The 1-year cardiovascular readmissions rate was 32.6%. RSMR were lower among patients discharged from high-volume hospitals (> 340 HF discharges) (in-hospital RSMR, 10.3+/-5.6%; 8.6+/-2.2%); P <.001). High-volume hospitals had higher 1-year RSRR (32.3+/-3.7%; 33.7+/-4.5%; P=.006). The availability of a cardiology department at the hospital was associated with better outcomes (in-hospital RSMR, 9.9+/-3.8%; 9.2+/-2.4%; P <.001). Conclusions: High-volume hospitals and the availability of a cardiology department were associated with lower in-hospital mortality

Surface electrocardiogram detects signs of right ventricular pressure overload among acute-decompensated heart failure with preserved ejection fraction patients.

BACKGROUND: Pulmonary hypertension (PH) is a common finding among patients with heart failure and preserved ejection fraction (HFpEF) and contributes to develop right ventricular systolic dysfunction (RVSD). AIMS: We evaluated the diagnostic accuracy of Flowers and Horan electrocardiographic criteria to detect significant right ventricular pressure overload. METHODS: 123 patients were prospectively included. We used the Flowers and Horan (FH) ECG criteria to define RV enlargement (score >10). Echocardiographic measurements were performed blinded to the electrocardiographic results. RESULTS: Severe PH was found in 51.5%. Seventeen patients (16.5%) had a FH score >10 points. This was associated to RVSD (RR 2.66; 1.51-4.67 CI 95%, p=0.002), with 90.5% specificity and 34.4% sensitivity and to severe PH (RR 1.70; 1.16-2.50 CI 95%, p=0.028) with 91.9% specificity and 27.5% sensitivity. CONCLUSIONS: The ECG is a useful tool to classify HFpEF patients with echocardiographic signs of right ventricular pressure overload, in the absence of RBBB.

Cardiorenal syndrome: an unsolved clinical problem.

The clinical relevance of the bidirectional cross-talk between heart and kidney is increasingly recognized. However, the optimal approach to the management of kidney dysfunction in heart failure remains unclear. The purpose of this article is to outline the most plausible pathophysiologic theories that attempt to explain the renal impairment in acute and chronic heart failure, and to review the current treatment strategies for these situations.
