Usefulness of risk scores and predictors of atrial fibrillation recurrence after elective electrical cardioversion.

INTRODUCTION: Electrical cardioversion (ECV) is a frequently used procedure for restoring sinus rhythm in atrial fibrillation (AF); however, the rate of recurrence is high. The identification of patients at high risk of recurrence could influence the decision-making process. The present study evaluates the predictive value of risk scores in atrial fibrillation recurrence after elective electrical cardioversion. METHODS: Unicentric, observational, and prospective study of adult patients who have undergone an elective ECV as rhythm control strategy between July 2017 and September 2022. RESULTS: From the 283 analyzed patients (mean age 63.95 ± 10.76212, 74.9% male); 99 had paroxysmal AF (35%) and 159 (59%) presented AF recurrence during a follow-up of 6 months. In patients with post-ECV AF recurrence, the period of time from diagnosis until the performance of the procedure was longer (393 ± 891 vs. 195 ± 527, p = .02). No paroxysmal AF (71.3% vs. 57.8%, p = .02) and LA dilatation with >40 mL/m2 (35.9% vs. 23.3%, p = .02) volumes were more frequent within these patients. AF recurrence was more frequent in patients who had previous ECV (HR = 1.32; 95% CI: 1.12-2.35; p = .01) and more than 1 shock to recover sinus rhythm (HR = 1.62; 95% CI: 1.07-1.63; p = .01). The SLAC, ALARMEc, ATLAS, and CAAP-AF scores were statistically significant, although with a moderate predictive capacity for post-ECV recurrence. CONCLUSIONS: Risk scores analyzed showed a modest value predicting AF recurrence after ECV. Previous ECV, and greater difficulty in restoring SR were independent predictors of recurrence.

[Differences among renin-angiotensin system inhibitor drugs in prognosis of hypertense patients with COVID-19]. / Diferencias entre fármacos inhibidores del sistema renina-angiotensina en pacientes hipertensos ingresados por COVID-19.

Introduction: Concerns have been raised about Renin-angiotensin system inhibitors (RASi) in patients with COVID-19. Although recent trials have proved its security, evidence regarding intrinsic differences between RASi is lacking, especially in patients with arterial hypertension. Our objective was to analyse the prognosis of hypertense patients who received angiotensin converting enzyme inhibitors (ACEi) or angiotensin-2 receptor blockers (ARBs) and were hospitalized due to COVID-19. Materials and methods: 392 consecutive patients with hypertension and COVID-19 were analyse. Incidence of the combined event (death or mechanical ventilation need) was the primary endpoint. Secondary, incidence of each event and time to event were analysed. Results: 155 received ACEi and 237 ARBs. During the hospitalization, the combined event was observed in the 31,6 % of patients. No differences were observed between those previously treated with ACEi and ARBs (33.5 vs. 30.9%; p = 0.51). In the survival analysis, no differences were observed regarding time to combined event (p = 0.91). In-hospital mortality was similar in both groups (32.3 vs. 29.1%; p = 0.51), as well as the need of mechanical ventilation (3.2 vs. 5.9%; p = 0.23). Conclusions: The type of RASi was not associated with in-hospital major events in patients with arterial hypertension hospitalized due to COVID-19.

Introducción: Han surgido dudas sobre la seguridad de los fármacos inhibidores del sistema renina-angiotensina (SRA) en pacientes con enfermedad por coronavirus 2019 (COVID-19). Aunque estudios recientes han demostrado la seguridad de este grupo de fármacos, la evidencia sobre la comparativa de los diferentes fármacos inhibidores del SRA es escasa, sobre todo en pacientes hipertensos. Nuestro objetivo fue analizar el pronóstico de los pacientes hipertensos tratados con inhibidores de la enzima convertidora de angiotensina (IECA) o antagonistas del receptor de angiotensina II (ARA II) que presentaron COVID-19. Materiales y métodos: Se analizaron 582 pacientes hipertensos con COVID-19. Se registró la incidencia del evento combinado de muerte o necesidad de ventilación mecánica invasiva (VMI) durante la hospitalización. De forma secundaria, se analizó la incidencia de eventos de manera independiente y se realizó un análisis de supervivencia para analizar el tiempo hasta los eventos. Resultados: 155 pacientes recibían tratamiento previo con IECA y 237 con ARA II. Durante la hospitalización por COVID-19, se observó una incidencia del evento combinado del 31.6%. No se detectaron diferencias entre los pacientes que recibían tratamiento con IECA y los tratados con ARA II (33.5 vs. 30.9%; p = 0.51). En el análisis de supervivencia, no se hallaron diferencias en el tiempo hasta el evento combinado (p = 0.91). La mortalidad intrahospitalaria fue similar en ambos grupos (32.3 vs. 29.1%; p = 0.51), así como la necesidad de VMI (3.2 vs. 5.9%; p = 0.23). Conclusiones: El tipo de inhibidor del SRA no se asoció a diferencias pronósticas significativas entre los pacientes hipertensos ingresados con COVID-19.

[Cardiovascular disease after COVID-19 infection in elderly patients. Results of annual follow-up of a cohort of survivors]. / Enfermedad cardiovascular tras infección por SARS-CoV-2 en pacientes ancianos. Resultados del seguimiento anual de una cohorte de supervivientes.

INTRODUCTION: Although the effects of SARS-CoV-2 infection on the cardiovascular system is well known in the acute phase, the cardiovascular impact of the elderly population surviving COVID-19 respiratory infection after 1 year of follow-up has not been sufficiently studied. METHODS: Observational registry of 240 elderly patients (75 years or older), consecutively admitted for COVID-19 respiratory infection and survivors of the same, between March 1 and April 30, 2020, at the Hospital General Universitario de Ciudad Real. The incidence of major cardiovascular events [MACE] (cardiovascular death [CD], acute coronary syndrome [ACS], cerebrovascular disease [CVD], venous thromboembolic disease [VTE] and heart failure [HF]) was prospectively analysed. RESULTS: The mean age was 83.75±5.75 years. After a mean follow-up of 352.2±70.4 days, 13.8% of patients died and 9.6% had MACE, the most frequent being heart failure, with no differences in severity or overall course of acute illness. In the multivariate Cox regression model, the risk of developing MACE was higher in patients with chronic obstructive pulmonary disease and (HR 4.29; 95%CI 1.62-11.39; P=.003) and loop diuretic (HR 2.99; 95%CI 1.27-7.07; P=.01). CONCLUSIONS: In elderly COVID-19 survivors, the incidence of MACE after one year of follow-up is high, the main manifestation being heart failure.

[Mortality and associated prognostic factors in elderly and very elderly hospitalized patients with respiratory disease COVID-19]. / Mortalidad y factores pronósticos asociados en pacientes ancianos y muy ancianos hospitalizados con infección respiratoria COVID-19.

INTRODUCTION: Elderly patients with COVID-19 has a worse clinical evolution, being more susceptible to develop serious manifestations. The differences between the elderly and very elderly population, mortality and associated prognostic factors of SARS-CoV-2 infection have not been enough studied yet. METHODS: An observational study of 416 elderly patients admitted consecutively to Hospital General Universitario de Ciudad Real for COVID-19 respiratory infection from March 1st to April 30th, 2020. Data were collected including patient demographic information, medical history, clinical characteristics, laboratory data, therapeutic interventions and clinical outcomes during the hospitalization and after discharge, until June 15, 2020 with the aim of analyzing mortality, and associated prognostic factors. RESULTS: The mean age was 84.43±5.74 years old; elderly patients (75-84 years) were 50.2% of the sample and very elderly (≥85 years) the remaining 49.8%. In Cox regression model, mortality rate was higher in very elderly group (HR = 2.58; 95% CI: 1.23-5.38; P = .01), hypertensive (HR = 3, 45; 95% CI: 1.13-10.5; P = .03) and chronic kidney disease patients (HR = 3.86; 95% CI: 1.3-11.43; P = .02). In contrast, calcium antagonists (HR = 0.27; 95% CI: 0.12-0.62; P = .002) and anticoagulant therapy during hospitalization (HR = 0.26; 95% CI: 0.08 0, 83; P = .02) were associated with a longer time free of mortality. CONCLUSIONS: Mortality rate was higher in very eldery patients compared with eldery; and in hypertensive and chronic kidney disease patients. Anticoagulation therapy and calcium chanel bloquers treatment during hospitalization were associated with a higher survival in the short-term follow-up in patients hospitalized with COVID-19.

Comparative analysis between the use of renin-angiotensin system antagonists and clinical outcomes of hospitalized patients with COVID-19 respiratory infection.

INTRODUCTION: Hypertension has been associated with worse outcomes in patients with COVID-19 infection, so concerns have been raised about the possibility that inhibitors of the renin-angiotensin system (RAS) could influence the prognosis of these patients. METHODS: This is an observational study of 921 consecutive patients admitted with COVID-19 respiratory infection to Hospital General Universitario Ciudad Real from March 1 to April 30, 2020. Following data were collected including patient demographic information, medical history, clinical characteristics, laboratory data, therapeutic interventions during the hospitalization and clinical outcomes. RESULTS: The mean age was 78 years, and 59.2% of patients had a history of hypertension. Patients with previous treatment with RAS inhibitor (42.4%) showed lower risk of the primary composite endpoint (mortality or need for invasive mechanical ventilation). Treatment with RAS inhibitor (both outpatient treatment and during hospitalization) had neither effect on mortality nor need for invasive ventilation. There were no differences in time-to-event analysis between groups. CONCLUSIONS: RAS inhibitor treatment prior to admission in patients with COVID-19 respiratory infection was associated with lower risk of the primary composite endpoint and did not show neither impact on mortality nor need for invasive mechanical ventilation, even if these drugs were prescribed during hospitalization.

INTRODUCCIÓN: La presencia de hipertensión arterial se asocia con peor pronóstico en pacientes con COVID-19, y se ha sugerido que el uso de inhibidores del eje renina-angiotensina puede influir en el pronóstico de los pacientes. MÉTODOS: Registro observacional de 921 pacientes consecutivos ingresados por infección respiratoria COVID-19 entre el 1 de marzo y el 30 abril de 2020 en el Hospital General Universitario de Ciudad Real. Se registraron datos clínicos y analíticos, intervenciones terapéuticas y desarrollo de eventos durante el ingreso hospitalario. RESULTADOS: La mediana de edad fue de 78 años y el 59,2% tenían hipertensión arterial. Aunque el perfil clínico fue más desfavorable en el grupo de pacientes con prescripción previa de IECA o ARA2 respecto al resto, los primeros presentaron menor riesgo de desarrollo del evento primario combinado (mortalidad total o necesidad de soporte ventilatorio invasivo). Asimismo, el empleo previo al ingreso o durante el mismo de estos fármacos mostró un efecto neutro sobre la mortalidad total y sobre la necesidad de ventilación mecánica invasiva. En el análisis de supervivencia no se observó mayor riesgo de presentar más precozmente ninguno de los eventos registrados. CONCLUSIONES: La prescripción previa al ingreso por infección respiratoria COVID-19 de inhibidores del eje renina-angiotensina se asoció a un menor riesgo de desarrollo del evento primario combinado y a un efecto neutro sobre la mortalidad total y sobre la necesidad de ventilación mecánica invasiva.

Acute myelitis and SARS-CoV-2 infection. A new etiology of myelitis?

The etiological agent of coronavirus disease-19 (COVID-19), SARS-coronavirus-2 (SARS-CoV-2), emerged in Wuhan, China, and quickly spread worldwide leading the World Health Organization (WHO) to recognize it not only as a pandemic but also as an important thread to public health. Beyond respiratory symptoms, new neurological manifestations are being identified such as headache, ageusia, anosmia, encephalitis or acute cerebrovascular disease. Here we report the case of an acute transverse myelitis (TM) in a patient with SARS-CoV-2 infection detected by the nasopharyngeal swab technique but not in cerebrospinal fluid (CSF) analysis. Anti-herpes simplex virus (HSV) 1 and varicella-zoster IgM antibodies were not detected in serum samples and spinal and brain magnetic resonance imaging (MRI) showed no abnormal findings. This case remarks that COVID-19 nervous system damage could be caused by immune-mediated mechanisms.

Impact of Treatment with Renin-Angiotensin System Inhibitors on Clinical Outcomes in Hypertensive Patients Hospitalized with COVID-19.

INTRODUCTION: Concerns have been raised about the possible harmfulness of angiotensin-converter enzyme inhibitors (ACEi) and aldosterone receptor blockers (ARB) in patients with COVID-19. However, few data from a European population have been published, especially from hypertensive patients. AIM: To study the association between ACEi or ARB treatments and major adverse outcomes during hospitalisation in COVID-19 patients. METHODS: We studied 545 consecutive hypertensive patients admitted to our institution due to COVID-19 with respiratory involvement. We analysed the incidence of combined event (death or mechanical ventilatory support) during hospitalisation, as well as the time to independent events. RESULTS: 188 (34.5%) patients presented the combined endpoint. 182 (33.4%) patients died, and 21 (3.9%) needed mechanical ventilatory support. Patients with previous treatment with ACEi or ARB presented similar incidence of the combined endpoint during hospitalisation (31.6% vs. 41.8%; p = 0.08), with a lower all-cause mortality rate (30.4% vs. 41.2%; p = 0.03) compared with those without prior treatment. Use of ACEi or ARB was not independently associated with lower incidence of the combined endpoint [Adjusted OR 0.675 (95% CI 0.298-1.528; p = 0.146)], but it was associated with lower mortality [Adjusted OR 0.550 (95% CI 0.304-0.930; p = 0.047)]. CONCLUSIONS: The use of ACEi or ARB was associated with less incidence of all-cause death during hospitalisation among hypertensive patients admitted with COVID-19 respiratory infection.
