Abstract

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.
