ABSTRACT
OBJECTIVES: Thromboinflammation, resulting from a complex interaction between thrombocytopathy, coagulopathy, and endotheliopathy, contributes to increased mortality in COVID-19 patients. MR-proADM, as a surrogate of adrenomedullin system disruption, leading to endothelial damage, has been reported as a promising biomarker for short-term prognosis. We evaluated the role of MR-proADM in the mid-term mortality in COVID-19 patients. METHODS: A prospective, observational study enrolling COVID-19 patients from August to October 2020. A blood sample for laboratory test analysis was drawn on arrival in the emergency department. The primary endpoint was 90-day mortality. The area under the curve (AUC) and Cox regression analyses were used to assess discriminatory ability and association with the endpoint. RESULTS: A total of 359 patients were enrolled, and the 90-day mortality rate was 8.9%. ROC AUC for MR-proADM predicting 90-day mortality was 0.832. An optimal cutoff of 0.80 nmol/L showed a sensitivity of 96.9% and a specificity of 58.4%, with a negative predictive value of 99.5%. Circulating MR-proADM levels (inverse transformed), after adjusting by a propensity score including eleven potential confounders, were an independent predictor of 90-day mortality (HR: 0.162 [95% CI: 0.043-0.480]) CONCLUSIONS: Our data confirm that MR-proADM has a role in the mid-term prognosis of COVID-19 patients and might assist physicians with risk stratification.

Nos complace presentar en REC: CardioClinics la cuarta edición de «Temas de actualidad en cardiología», correspondiente al año 2021. Este ha sido un año singular, en el que la enfermedad coronavírica de 2019 (COVID-19) ha estado presente durante los últimos meses y ha marcado pautas en la asistencia clínica e investigación cardiovascular. Sin embargo, a diferencia del primer año de pandemia, hemos asistido a un retorno paulatino y progresivo a la normalidad, en el que hemos convivido con la COVID-19 y en el que se ha continuado con la innovadora experiencia de comunicación y divulgación científica en formato virtual (como en el Congreso Europeo de Cardiología, 2021-Experiencia digital), a la vez que con el formato tradicional, mediante reuniones presenciales con los matices propios de las normas de seguridad, como el vivido en el congreso de nuestra sociedad.
ABSTRACT
Los fármacos antitrombóticos son un pilar fundamental en el tratamiento y prevención de las enfermedades cardiovasculares. A pesar de la amplia experiencia previa, en los últimos años se han producido importantes novedades en la práctica clínica que han modificado estrategias terapéuticas en diferentes escenarios como en el campo de la fibrilación auricular, la cardiopatía isquémica o el intervencionismo coronario percutáneo. A todo esto se debe que añadir el papel fundamental del tratamiento antitrombótico durante la reciente pandemia de COVID-19 y sus implicaciones dado el estado protrombótico que produce la infección por el virus SARS-CoV-2. Desde el Grupo de Trabajo de Trombosis Cardiovascular de la Sociedad Española de Cardiología, se ha sintetizado la evidencia científica reciente en el presente documento.
ABSTRACT
Resumen Los fármacos antitrombóticos son un pilar fundamental en el tratamiento y prevención de las enfermedades cardiovasculares. A pesar de la amplia experiencia previa, en los últimos años se han producido importantes novedades en la práctica clínica que han modificado estrategias terapéuticas en diferentes escenarios como en el campo de la fibrilación auricular, la cardiopatía isquémica o el intervencionismo coronario percutáneo. A todo esto se debe que añadir el papel fundamental del tratamiento antitrombótico durante la reciente pandemia de COVID-19 y sus implicaciones dado el estado protrombótico que produce la infección por el virus SARS-CoV-2. Desde el Grupo de Trabajo de Trombosis Cardiovascular de la Sociedad Española de Cardiología, se ha sintetizado la evidencia científica reciente en el presente documento. Antithrombotic drugs play a key role in the treatment and prevention of cardiovascular diseases. Despite the previous knowledge, important developments in clinical practice have been reported in the last few years, especially in the field of atrial fibrillation, coronary heart disease and percutaneous coronary intervention. Moreover, it is important to highlight the role of antithrombotic therapy in the current COVID-19 pandemic, since the infection caused by the new coronavirus SARS-Cov-2 has been associated with a prothrombotic state. This paper by the Working Group on Cardiovascular Thrombosis of the Spanish Society of Cardiology aims at summarizing the current information available in this complex scenario.

BACKGROUND: Early identification of patients at high risk of progression to severe COVID-19 constituted an unsolved challenge. Although growing evidence demonstrates a direct association between endotheliitis and severe COVID-19, the role of endothelial damage biomarkers has been scarcely studied. We investigated the relationship between circulating mid-regional proadrenomedullin (MR-proADM) levels, a biomarker of endothelial dysfunction, and prognosis of SARS-CoV-2-infected patients. METHODS: Prospective observational study enrolling adult patients with confirmed COVID-19. On admission to emergency department, a blood sample was drawn for laboratory test analysis. Primary and secondary endpoints were 28-day all-cause mortality and severe COVID-19 progression. Area under the curve (AUC) and multivariate regression analysis were employed to assess the association of the biomarker with the established endpoints. RESULTS: A total of 99 patients were enrolled. During hospitalization, 25 (25.3%) cases progressed to severe disease and the 28-day mortality rate was of 14.1%. MR-proADM showed the highest AUC to predict 28-day mortality (0.905; [CI] 95%: 0.829-0.955; P < .001) and progression to severe disease (0.829; [CI] 95%: 0.740-0.897; P < .001), respectively. MR-proADM plasma levels above optimal cut-off (1.01 nmol/L) showed the strongest independent association with 28-day mortality risk (hazard ratio [HR]: 10.470, 95% CI: 2.066-53.049; P < .005) and with progression to severe disease (HR: 6.803, 95% CI: 1.458-31.750; P = .015). CONCLUSION: Mid-regional proadrenomedullin was the biomarker with highest performance for prognosis of death and progression to severe disease in COVID-19 patients and represents a promising predictor for both outcomes, which might constitute a potential tool in the assessment of prognosis in early stages of this disease.
