Cell-free DNA and Microvascular Damage in ST-segment Elevation Myocardial Infarction Treated With Primary Percutaneous Coronary Intervention.
INTRODUCTION AND OBJECTIVES Cell-free DNA (cfDNA) in ST-segment elevation myocardial infarction might originate from hyperactivated leukocytes at the coronary lesion. Our aim was to investigate the relationship between cfDNA and coronary reperfusion. METHODS We studied 116 patients treated with primary angioplasty using thrombus aspiration. Coronary (during aspiration) and peripheral (at the end of the procedure) blood samples were drawn for cfDNA, as well as high-sensitivity troponin T and myeloperoxidase quantification. The primary endpoint was no ST-segment resolution (STR) (≥ 70%) and the secondary endpoint was lack of final Thrombolysis In Myocardial Infarction flow 3 (TIMI 3). RESULTS…
Similar Clinical Course and Significance of Circulating Innate and Adaptive Immune Cell Counts in STEMI and COVID-19
This study aimed to assess the time course of circulating neutrophil and lymphocyte counts and their ratio (NLR) in ST-segment elevation myocardial infarction (STEMI) and coronavirus disease (COVID)-19 and explore their associations with clinical events and structural damage. Circulating neutrophil, lymphocyte and NLR were sequentially measured in 659 patients admitted for STEMI and in 103 COVID-19 patients. The dynamics detected in STEMI (within a few hours) were replicated in COVID-19 (within a few days). In both entities patients with events and with severe structural damage displayed higher neutrophil and lower lymphocyte counts. In both scenarios, higher maximum neutrophil and lower mi…
ADN libre y daño microvascular en el infarto agudo de miocardio con elevación del segmento ST tratado con intervención coronaria primaria
Resumen Introduccion y objetivos En el infarto agudo de miocardio con elevacion del segmento ST, el ADN libre circulante podria originarse de los leucocitos activados en la lesion coronaria. El objetivo fue investigar la relacion entre el ADN libre y la reperfusion coronaria. Metodos Se incluyo a 116 pacientes, tratados con angioplastia primaria y tromboaspiracion. Se cuantifico el ADN libre coronario (durante la aspiracion) y periferico (al final del procedimiento), asi como la troponina T ultrasensible y la mieloperoxidasa. El objetivo primario fue la no resolucion del segmento ST (RST) (≥ 70%) y el secundario la ausencia de flujo Thrombolysis In Myocardial Infarction 3 (TIMI 3) final. Re…
Growth differentiation factor 15 and geriatric conditions in acute coronary syndrome
Abstract Background Growth differentiation factor 15 (GDF-15) is a marker of cell senescence. Age is a well-known determinant of GDF-15 levels, yet no study has analyzed the relationship between geriatric conditions and GDF-15. We hypothesize that geriatric conditions reflecting biological age might be stronger determinants of GDF-15 than chronological age in elderly patients with acute coronary syndrome. Methods A total of 208 patients (mean age = 78.3 ± 7.0 years) were included. Prior to discharge, a thorough geriatric assessment was performed and GDF-15 measured. Predictors of GDF-15 (transformed by its natural logarithm) were determined with linear regression. Furthermore, Cox regressio…
CA125-Guided Diuretic Treatment Versus Usual Care in Patients With Acute Heart Failure and Renal Dysfunction
BACKGROUND: The optimal diuretic treatment strategy for patients with acute heart failure and renal dysfunction remains unclear. Plasma carbohydrate antigen 125 (CA125) is a surrogate of fluid overload and a potentially valuable tool for guiding decongestion therapy. The aim of this study was to determine if a CA125-guided diuretic strategy is superior to usual care in terms of short-term renal function in patients with acute heart failure and renal dysfunction at presentation. METHODS: This multicenter, open-label study randomized 160 patients with acute heart failure and renal dysfunction into 2 groups (1:1). Loop diuretics doses were established according to CA125 levels in the CA125-gui…
