Pulmonary Embolism: Contemporary Medical Management and Future Perspectives

2018

Pulmonary embolism (PE) contributes substantially to the global disease burden. A key determinant of early adverse outcomes is the presence (and severity) of right ventricular dysfunction. Consequently, risk-adapted management strategies continue to evolve, tailoring acute treatment to the patients' clinical presentation, hemodynamic status, imaging and biochemical markers, and comorbidity. For subjects with hemodynamic instability or 'high-risk' PE, immediate systemic reperfusion treatment with intravenous thrombolysis is indicated; emerging approaches such as catheter-directed pharmacomechanical reperfusion might help to minimize the bleeding risk. Currently, direct, non-vitamin K-depende…

Mesenchymal Stem Cells Provide Better Results Than Hematopoietic Precursors for the Treatment of Myocardial Infarction

2010

Objectives The purpose of this study was to compare the ability of human CD34(+) hematopoietic stem cells and bone marrow mesenchymal stem cells (MSC) to treat myocardial infarction (MI) in a model of permanent left descendent coronary artery (LDA) ligation in nude rats. Background Transplantation of human CD34(+) cells and MSC has been proved to be effective in treating MI, but no comparative studies have been performed to elucidate which treatment prevents left ventricular (LV) remodelling more efficiently. Methods Human bone marrow MSC or freshly isolated CD34(+) cells from umbilical cord blood were injected intramyocardially in infarcted nude rats. Cardiac function was analyzed by echoc…

A meta-analysis of the effect size of rheumatoid arthritis on left ventricular mass: comment on the article by Rudominer et al

2009

We appreciate the work of Rudominer et al, who recently published a report describing the association of rheumatoid arthritis (RA) with increased left ventricular mass.

Implicación de la escara miocárdica en la predicción y tratamiento de la taquicardia ventricular postinfarto

2017

INTRODUCCIÓN Y OBJETIVOS: La taquicardia ventricular (TV) es una arritmia peligrosa y una causa importante de muerte súbita en pacientes que han padecido un infarto previo. Las escaras ventriculares tras infarto son un sustrato que favorece la reentrada eléctrica, que es el mecanismo más frecuente de taquicardia ventricular. Intentar entender el potencial arritmogénico de la escara ayudaría por una parte a identificar precozmente pacientes en riesgo de padecer taquicardias ventriculares de lo que podrían derivar actuaciones clínicas, y por otra parte, su tratamiento una vez se ha presentado la arritmia, modificando las características de dicha escara mediante ablación con catéter. Esta tesi…
