Mortality risk factors in patients with SARS-CoV-2 infection and atrial fibrillation: Data from the SEMI-COVID-19 registry. / Factores de riesgo de mortalidad en pacientes con infección por SARS-CoV-2 y fibrilación auricular: datos del registro SEMI-COVID-19.

INTRODUCTION: Atrial fibrillation and associated comorbidities pose a risk factor for mortality, morbidity and development of complications in patients admitted for COVID-19. OBJECTIVES: To describe the clinical, epidemiological, radiological and analytical characteristics of patients with atrial fibrillation admitted for COVID-19 in Spain. Secondarily, we aim to identify those variables associated with mortality and poor prognosis of COVID-19 in patients with atrial fibrillation. METHODS: Retrospective, observational, multicenter, nationwide, retrospective study of patients hospitalized for COVID-19 from March 1 to October 1, 2020. Data were obtained from the SEMI-COVID-19 Registry of the Spanish Society of Internal Medicine (SEMI) in which 150 Spanish hospitals participate. RESULTS: Between March 1 and October 1, 2020, data from a total of 16,461 patients were entered into the SEMI-COVID-19 registry. 1816 (11%) had a history of atrial fibrillation and the number of deaths among AF patients amounted to 738 (41%). Regarding clinical characteristics, deceased patients were admitted with a higher heart rate (88.38 vs. 84.95; P>0.01), with a higher percentage of respiratory failure (67.2 vs. 20.1%; P<0.01) and high tachypnea (58 vs. 30%; P<0.01). The comorbidities that presented statistically significant differences in the deceased group were: age, hypertension and diabetes with target organ involvement. There was also a higher prevalence of a history of cardiovascular disease in the deceased. On multivariate analysis, DOACs treatment had a protective role for mortality (OR: 0.597; CI: 0.402-0.888; P=0.011). CONCLUSIONS: Previous treatment with DOACs and DOACs treatment during admission seem to have a protective role in patients with atrial fibrillation, although this fact should be verified in prospective studies.

Introducción: La fibrilación auricular y las comorbilidades asociadas a ella suponen un factor de riesgo de mortalidad, morbilidad y desarrollo de complicaciones en los pacientes ingresados por COVID-19. Objetivos: Describir las características clínicas, epidemiológicas, radiológicas y analíticas de los pacientes con FA ingresados por COVID-19 en España. De forma secundaria, se pretende identificar aquellas variables que se asocian con mortalidad y mal pronóstico de la COVID-19 en pacientes que presentan FA. Métodos: Estudio retrospectivo, observacional y multicéntrico de ámbito nacional de pacientes hospitalizados por COVID-19 desde el 1 de marzo al 1 de octubre de 2020. Los datos fueron obtenidos del Registro SEMI-COVID-19 de la Sociedad Española de Medicina Interna (SEMI) en el que participan 150 hospitales españoles. Resultados: De un total de 16.461 pacientes en el registro SEMI-COVID-19, 1.816 (11%) tenían antecedente de FA y el número de fallecidos entre los pacientes con FA ascendió a 738 (41%). En cuanto a la clínica, los pacientes fallecidos ingresaron con una frecuencia cardíaca mayor (88,38 vs 84,95; p > 0,01), con mayor porcentaje de insuficiencia respiratoria (67,2% vs 20,1%; p < 0,01) y mayor taquipnea (58% vs 30%; p < 0,09). En el análisis multivariante, el tratamiento con ACOD tuvo un papel protector para la mortalidad por infección por COVID 19 (OR:0,597; IC (0,402-0,888; p = 0.011). Conclusiones: El tratamiento previo con ACOD como el tratamiento con ACOD durante el ingreso parecen tener un papel protector en los pacientes con FA, aunque este hecho debería ser comprobado con estudios prospectivos.

Heart failure and in-hospital mortality in elderly patients after elective noncardiac surgery in Spain.

BACKGROUND: Patients with heart failure (HF) undergoing noncardiac surgical procedures is rising worldwide. This study was aiming at analyzing the impact of heart failure (HF) on the outcomes (mortality, complications, readmissions, and length of stay) of elderly patients undergoing elective major noncardiac surgical procedures in Spain. METHODS: A retrospective observational study of patients undergoing noncardiac surgery was conducted. The Minimum Basic Data Set (MBDS) was used to collect information about the demographic characteristics of patients discharged from hospitals of the Spanish National Health System (SNHS), variables related to patients' medical conditions and surgeries conducted during the episode. RESULTS: A total of 996,986 selected procedures in the discharge record were identified in the period 2007-2015. HF was recorded as a secondary diagnosis in 22,367 discharges (2.24%). The mean age of patients was 76.6±7.27 years, with a difference in patients without and with HF: 76.5 (95% CI: 76.47-76.50) vs 82.8 (95% CI: 82.71-82.90). The number of selected surgical procedures increased by 13.2% (117,487 in 2015 vs. 103,744 in 2007), and the proportion of presence HF as a comorbidity increased by 24.4% (2.4% in 2015 v 1.9% in 2007). The proportion of women was higher in the HF group: 53.2% (95% CI: 53.18-53.22) vs 64.3% (95% CI: 64.20-64.44), with a longer average length of stay: 7.9 (95% CI: 7.9-7.9) vs 14.9 (95% CI 14.7-15.0) days, and women had a higher proportion of comorbidities. HF was found to be an independent risk factor in-hospital mortality in the multilevel risk adjustment model (OR=2.3; 95% CI: 2.2-2.4). CONCLUSIONS: Patients with HF undergoing any of the selected surgical procedures are older; there was women predominance and there is also an important burden of comorbidities than patients without HF undergoing these surgical procedures. HF in the selected procedures, increasing in-hospital mortality, mean length of stay, and the occurrence of adverse events in the Spanish population. The percentage of patients with HF who underwent the selected surgical procedures increased in the study period.

Impact of Heart Failure on In-Hospital Outcomes after Surgical Femoral Neck Fracture Treatment.

BACKGROUND: Femoral neck fracture (FNF) is a common condition with a rising incidence, partly due to aging of the population. It is recommended that FNF should be treated at the earliest opportunity, during daytime hours, including weekends. However, early surgery shortens the available time for preoperative medical examination. Cardiac evaluation is critical for good surgical outcomes as most of these patients are older and frail with other comorbid conditions, such as heart failure. The aim of this study was to determine the impact of heart failure on in-hospital outcomes after surgical femoral neck fracture treatment. METHODS: We performed a retrospective study using the Spanish National Hospital Discharge Database, 2007-2015. We included patients older than 64 years treated for reduction and internal fixation of FNF. Demographic characteristics of patients, as well as administrative variables, related to patient's diseases and procedures performed during the episode were evaluated. RESULTS: A total of 234,159 episodes with FNF reduction and internal fixation were identified from Spanish National Health System hospitals during the study period; 986 (0.42%) episodes were excluded, resulting in a final study population of 233,173 episodes. Mean age was 83.7 (±7) years and 179,949 (77.2%) were women (p < 0.001). In the sample, 13,417 (5.8%) episodes had a main or secondary diagnosis of heart failure (HF) (p < 0.001). HF patients had a mean age of 86.1 (±6.3) years, significantly older than the rest (p < 0.001). All the major complications studied showed a higher incidence in patients with HF (p < 0.001). Unadjusted in-hospital mortality was 4.1%, which was significantly higher in patients with HF (18.2%) compared to those without HF (3.3%) (p < 0.001). The average length of stay (LOS) was 11.9 (±9.1) and was also significantly higher in the group with HF (16.5 ± 13.1 vs. 11.6 ± 8.7; p < 0.001). CONCLUSIONS: Patients with HF undergoing FNF surgery have longer length of stay and higher rates of both major complications and mortality than those without HF. Although their average length of stay has decreased in the last few years, their mortality rate has remained unchanged.
