The Influence of Risk Factors on the Choice of Therapeutic Method in Peripheral Arterial Disease

2020

Abstract Peripheral arterial disease (PAD) is characterized by obstruction in the lower limbs, mainly due to atherosclerosis. The prevalence of the pathology in people under 40 years of age is 6% and 15-20% in the population over 65 years old.(1,2) Approximately 50% of the affected persons are, at the time of examination, asymptomatic.(3) The most important risk factors associated with this condition are smoking, diabetes mellitus (DM), high cholesterol and high blood pressure (HBP). The current study shows that, regardless of the association of risk factors or pre-hospital treatment, these patients do not benefit from a certain type of treatment (drug or interventional), which corresponds …

Multimodality Imaging in Ischemic Cardiomyopathy

2019

Abstract Ischemic heart disease is the most common heart pathology in medical practice. Proper assessment of the size of myocardium injury and its consequences on the heart function is extremely important both for a correct drug therapy and for interventional approach. Most frequently the left ventricle is affected. The need for accurate evaluation of the impact of left ventricular myocardial damage has led to the development of new imaging techniques and improvement of the existing ones. At the moment the most commonly used imaging method for the assessment of left ventricular function is echocardiography. Cardiac Magnetic Resonance and nuclear tomography are precious imaging techniques as…

Conceptos básicos en biología molecular relacionados con la genética y la epigenética

2017

Resumen La observacion de que «lo mismo no sirve para todos» en la prevencion y el tratamiento de las enfermedades cardiovasculares, entre otras, ha propulsado el concepto de medicina de precision. Su objetivo es proporcionar las mejores intervenciones basadas en la informacion adicional que aporta el genoma. El genoma humano se compone de miles de millones de pares de bases que contienen un codigo que controla como se expresan los genes. Este codigo depende de reguladores no estaticos que rodean el ADN y constituyen el epigenoma. Ademas, los factores ambientales tambien desempenan un papel importante en esta compleja regulacion. Se presenta una perspectiva general sobre los conceptos basic…

El suero de seno coronario tras un infarto de miocardio induce angiogénesis y reparación de la obstrucción microvascular. Implicación del factor indu…

2018

Resumen Introduccion y objetivos El objetivo es estudiar la angiogenesis coronaria inducida por el suero coronario y la implicacion del factor inducible por hipoxia-1A (FIH-1A) en la reparacion de la obstruccion microvascular (OMV) tras un infarto agudo de miocardio (IAM). Metodos Se indujo un IAM en cerdos mediante oclusion coronaria durante 90 min. Se dividio a los animales entre 1 grupo de control y 4 grupos con IAM: sin reperfusion y 1 min, 1 semana y 1 mes tras la reperfusion. Se cuantificaron la OMV y la densidad microvascular. Se determino la capacidad angiogenica del suero coronario mediante una prueba de tubulogenesis in vitro. Se determinaron las concentraciones circulantes del FI…

Système endocannabinoïde : effets sur le métabolisme glucidique, mais aussi lipidique

2016

Resume Le systeme endocannabinoide (SEC) est compose de recepteurs couples aux proteines G : Cannabinoid type 1-receptor (CB 1 -R) et Cannabinoid type 2-receptor (CB 2 -R), de leurs ligands endogenes (anandamide [AEA], et 2-acylglycerol [2-AG]), et des enzymes responsables de leur synthese et de leur degradation. Bien que les recepteurs CB 1 -R et CB 2 -R furent initialement decrits au niveau du systeme nerveux central, ils sont presents dans de nombreux tissus peripheriques, ou ils sont impliques dans le metabolisme, la croissance, et l’inflammation. Apres le retrait commercial du rimonabant, pour des effets secondaires psychiatriques, un agoniste inverse du recepteur CB 1 (CB 1 -R), desti…

Association Between Fatty Acids of Blood Cell Membranes and Incidence of Coronary Heart Disease

2019

Objective— To examine the associations between baseline levels of fatty acids in blood cell membranes and their 1-year changes with the incidence of coronary heart disease (CHD) in older adults at high cardiovascular disease risk. Approach and Results— This is a case-control study nested in the PREDIMED trial (Prevención con Dieta Mediterránea), with 136 CHD cases and 272 controls (matched on age, sex, body mass index, intervention group, and time of permanence in the study to the time event). We used gas chromatography to measure the proportion of 22 fatty acids in blood cell membranes at baseline and after 1 year. Conditional logistic regression was used to estimate odds ratios (ORs) and…
