[Markers of myocardial injury in the prediction of short-term COVID-19 prognosis]. / Marcadores de daño miocárdico en la predicción del pronóstico a corto plazo de los pacientes con COVID-19.

INTRODUCTION AND OBJECTIVES: COVID-19 is currently causing high mortality and morbidity worldwide. Information on cardiac injury is scarce. We aimed to evaluate cardiovascular damage in patients with COVID-19 and determine the correlation of high-sensitivity cardiac-specific troponin T (hs-cTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) with the severity of COVID-19. METHODS: We included 872 consecutive patients with confirmed COVID-19 from February to April 2020. We tested 651 patients for high-sensitivity troponin T (hs-TnT) and 506 for NT-proBNP on admission. Cardiac injury was defined as hs-TnT > 14 ng/L, the upper 99th percentile. Levels of NT-proBNP > 300 pg/mL were considered related to some extent of cardiac injury. The primary composite endpoint was 30-day mortality or mechanical ventilation (MV). RESULTS: Cardiac injury by hs-TnT was observed in 34.6% of our COVID-19 patients. Mortality or MV were higher in cardiac injury than noncardiac injury patients (39.1% vs 9.1%). Hs-TnT and NT-proBNP levels were independent predictors of death or MV (HR, 2.18; 95%CI, 1.23-3.83 and 1.87 (95%CI, 1.05-3.36), respectively) and of mortality alone (HR, 2.91; 95%CI, 1.211-7.04 and 5.47; 95%CI, 2.10-14.26, respectively). NT-ProBNP significantly improved the troponin model discrimination of mortality or MV (C-index 0.83 to 0.84), and of mortality alone (C-index 0.85 to 0.87). CONCLUSIONS: Myocardial injury measured at admission was a common finding in patients with COVID-19. It reliably predicted the occurrence of mortality and need of MV, the most severe complications of the disease. NT-proBNP improved the prognostic accuracy of hs-TnT.

Intracoronary lithotripsy for calcific neoatherosclerotic in-stent restenosis: a case report.

BACKGROUND: In-stent restenosis is a difficult percutaneous scenario if calcific neoatherosclerosis is the underlying aetiology. CASE SUMMARY: A 69-year-old diabetic woman with a previous percutaneous coronary intervention on the left anterior descending coronary artery was readmitted for non-ST-elevation myocardial infarction. In-stent restenosis due to calcific neoatherosclerosis was observed by intracoronary imaging during the intervention. Intravascular lithotripsy was used successfully to fracture the underlying calcific plaque. However, the balloon ruptured during treatment although this did not damage the artery. DISCUSSION: Intravascular lithotripsy is a promising tool for the treatment of extremely calcified lesions including calcific neoatherosclerosis of in-stent restenosis. Balloon rupture is a complication of this new percutaneous treatment that has not previously been described.

Marcadores de daño miocárdico en la predicción del pronóstico a corto plazo de los pacientes con COVID-19 / Markers of myocardial injury in the prediction of short-term COVID-19 prognosis

INTRODUCCIÓN Y OBJETIVOS: La información sobre el daño miocárdico en la población con COVID-19 es muy escasa. Nuestro objetivo fue evaluar el daño cardiaco en pacientes con COVID-19 y determinar la correlación entre las concentraciones de troponina T ultrasensible (TnT-us) y fracción aminoterminal del propéptido natriurético cerebral (NT-proBNP) con la gravedad del COVID-19. MÉTODOS: Se incluyó a 872 pacientes consecutivos con COVID-19 confirmada desde febrero a abril de 2020. Se determinó al ingreso la TnT-us a 651 pacientes y la NT-proBNP a 506. El daño miocárdico se definió como una TnT-us> 14 ng/l,> percentil 99. La cifras de NT-proBNP> 300 pg/ml se consideraron relacionadas con daño miocárdico. El objetivo primario es muerte o ventilación mecánica (VM) a 30 días. RESULTADOS: Se observó daño miocárdico según la TnT-us en el 34,6%. Las tasas del evento muerte o VM fue superior en los pacientes con daño miocárdico (el 39,1 frente al 9,1%). Los valores de TnT-us y NT-proBNP fueron predictores independientes de muerte o VM (HR=2,18; IC95%, 1,23-3,83, y HR=1,87; IC95%, 1,05-3,36), y de mortalidad total (HR=2,91; IC95%, 1,211-7,04, y HR=5,47; IC95%, 2,10-14,26). Se observó que la NT-proBNP mejoró de manera significativa el modelo predictivo de la troponina para muerte o VM (estadístico C, 0,83-0,84) y mortalidad total (estadístico C, 0,85-0,87). CONCLUSIONES: El daño miocárdico analizado al ingreso se observó con frecuencia entre los pacientes con COVID-19 y es un potente predictor de muerte y necesidad de VM. La NT-proBNP mejoró la precisión pronóstica de la determinación de troponina
