Paradoxical attenuation of leukocyte rolling in response to ischemia- reperfusion and extracorporeal blood circulation in inflamed tissue.

2005

In contrast to acute preparations such as the exteriorized mesentery or the cremaster muscle, chronically instrumented chamber models allow one to study the microcirculation under “physiological” conditions, i.e., in the absence of trauma-induced leukocyte rolling along the venular endothelium. To underscore the importance of studying the naive microcirculation, we implanted titanium dorsal skinfold chambers in hamsters and used intravital fluorescence microscopy to study venular leukocyte rolling in response to ischemia-reperfusion injury or extracorporeal blood circulation. The experiments were performed in chambers that fulfilled all well-established criteria for a physiological microcir…

Hipercolesterolemia familiar homocigota: adaptación a España del documento de posición del grupo de consenso sobre hipercolesterolemia familiar de la…

2015

Homozygous familial hypercholesterolaemia (HoFH) is a rare life-threatening disease characterized by markedly elevated circulating levels of low-density lipoprotein cholesterol (LDL-C) and accelerated, premature atherosclerotic cardiovascular disease (ACVD). The Consensus Panel on Familial Hypercholesterolaemia of the European Atherosclerosis Society (EAS) has recently published a clinical guide to diagnose and manage HoFH (Eur Heart J. 2014;35:2146-57). Both the Spanish Society of Atherosclerosis (SEA) and Familial Hypercholesterolaemia Foundation (FHF) consider this European Consensus document of great value and utility. However, there are particularities in our country which advise to ha…

Pragmatic Analysis of Dyslipidemia Involvement in Coronary Artery Disease: A Narrative Review

2020

Background: Dyslipidemia is the main factor involved in the occurrence and progression of coronary artery disease. Objective: The research strategy is aimed at analyzing new data on the pathophysiology of dyslipidemia involvement in coronary artery disease, the modalities of atherogenic risk estimation and therapeutic advances. Method: Scientific articles published in PubMed from January 2017 to February 2018 were searched using the terms "dyslipidemia" and "ischemic heart disease". Results: PCSK9 contributes to the increase in serum levels of low-density lipoprotein-cholesterol and lipoprotein (a). The inflammation is involved in the progression of hyperlipidemia and atherosclerosis. Hype…

Fibratos: efectos farmacológicos

2012

Fibrates have demonstrated efficacy in modifying the various parameters of atherogenic dyslipidemia. The best known fibrate is fenofibrate, which is indicated for the treatment of hypertriglyceridemia with or without low high-density lipoprotein cholesterol (HDL-c) and the treatment of atherogenic dyslipidemia in patients with statin intolerance or contraindications. Fenofibrate is also indicated in association with statins in patients with high cardiovascular risk when HDL-c and triglyceride (TG) concentrations are poorly controlled. The lipid-lowering effects of fenofibrate are mediated by activation of the nuclear transcription factor PPARα, which leads to an increase of lipolysis and pl…

Thrombolysis for massive pulmonary embolism in pregnancy: a case report

2011

Mortality from pulmonary embolism (PE) in pregnancy might be related to challenges in targeting the right population for prevention. Such targeting could help ensure that the correct diagnosis is suspected and adequately investigated, and allow the initiation of the timely and best possible treatment of this disease. In the literature to date only 18 case reports of thrombolysis in pregnant women with PE have been reported, and showed beneficial effects for both mother and fetus in terms of mortality and complications with acceptable bleeding risks. We present here the case of a pregnant patient with massive PE who underwent successful thrombolysis. A 26-year-old pregnant (at 24 weeks) woma…

Abnormalities of the umbilico-portal venous system in Down syndrome: A report of two new patients

2003

Congenital anomalies of the umbilical and portal venous system are rare vascular malformations which are often associated with anomalies of the heart and gastrointestinal tract. Association with chromosomal disorders has been sporadically reported. We now report on two patients with trisomy 21 and congenital anomalies of the umbilico-portal system. A male fetus showed absence of the intrahepatic portal vein (PV) and ductus venosus with a direct communication between portal sinus and inferior vena cava exhibiting an umbilicosystemic total shunt during the fetal life and a portosystemic total shunt after birth. A female infant showed absence of the intrahepatic PV and a total portocaval shunt…

Filamin C variants are associated with a distinctive clinical and immunohistochemical arrhythmogenic cardiomyopathy phenotype.

2020

Background: Pathogenic variants in the filamin C (FLNC) gene are associated with inherited cardiomyopathies including dilated cardiomyopathy with an arrhythmogenic phenotype. We evaluated FLNC variants in arrhythmogenic cardiomyopathy (ACM) and investigated the disease mechanism at a molecular level. Methods: 120 gene-elusive ACM patients who fulfilled diagnostic criteria for arrhythmogenic right ventricular cardiomyopathy (ARVC) were screened by whole exome sequencing. Fixed cardiac tissue from FLNC variant carriers who had died suddenly was investigated by histology and immunohistochemistry. Results: Novel or rare FLNC variants, four null and five variants of unknown significance, were id…
