RESUMEN
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.

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.

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.

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.
