Objetivo. El manual pretende ser una guía, accesible y fácil de consultar, que oriente a los profesionales en la elaboración o adaptación de documentos basados en la evidencia que ayuden a la estandarización de la práctica clínica y a la toma de decisiones velando siempre por la calidad de la misma de forma que siga unos referentes establecidos. Material y métodos. La Comisión de Atención Sanitaria Basada en la Evidencia (CASBE), perteneciente a la estructura de calidad del Hospital Universitario Virgen del Rocío, propuso elaborar un manual para la elaboración de documentos basados en la evidencia que incorpore la relación de productos, la descripción de sus características, atributos, utilidad, metodología de elaboración y ámbito de aplicación de cada uno de ellos. Resultados. El manual contiene 7 herramientas basadas en la evidencia, un capítulo sobre metodología de análisis crítico de la literatura científica, un capítulo con recursos en Internet y anexos con herramientas de evaluación. Conclusiones. Este manual ofrece grandes oportunidades para la mejora de la calidad a los clínicos como guía de estandarización de la práctica asistencial, a los gestores como estrategia para promover y fomentar la elaboración de documentos que ayuden a reducir la variabilidad de la práctica clínica y a los pacientes la oportunidad de participar en la planificación de sus cuidados(AU)

Objectives. This handbook is intended to be an accessible, easy-to-consult guide to help professionals produce or adapt Evidence-Based Documents. Such documents will help standardize both clinical practice and decision-making, the quality always being monitored in such a way that established references are complied with. Materials and methods. Evidence-Based Health Care Committee, a member of “Virgen del Rocío” University Hospital quality structure, proposed the preparation of a handbook to produce Evidence-Based Documents including: a description of products, characteristics, qualities, uses, methodology of production, and application scope of every one of them.

Cardiac allograft vasculopathy: coronary computed tomography and virtual histology assessment.

INTRODUCTION: Cardiac allograft vasculopathy remains the leading cause of late morbidity and mortality in heart transplantation. The main diagnostic methods, coronary angiography or intracoronary ultrasound (when angiography is normal), are invasive. Other study methods, such as coronary computed tomography (CT) and virtual histological analysis, have not been widely assessed in this condition. OBJECTIVE: The objective of this study was to assess the correlation between data obtained from analysis of virtual histology compared with those obtained from the performance of coronary CT in cardiac transplant recipients. MATERIALS AND METHODS: During the same admission we performed coronary angiography and intravascular ultrasound with virtual histological analysis (automatic pull-back in anterior descending artery and one additional vessel if the former was normal) as well as coronary CT. RESULTS: The study included 10 patients. Virtual histology was done in segments with intimal thickening>0.5 mm, defining 2 groups of plaque, those with an inflammatory component (necrotic core>30% and calcium) versus those without it defined as the combination of both being <30%. A calcium component of the inflammatory plaque allowed coronary CT detection. CONCLUSIONS: The detection of inflammatory plaque in graft vessel disease can be based on an initial noninvasive method, such as coronary CT, although confirmation requires further study.

Safety and effectiveness of ivabradine after cardiac transplantation.

BACKGROUND: Heart denervation is the primary cause of sinus tachycardia in transplant recipients. Drugs are usually needed to treat associated symptoms. OBJECTIVE: To evaluate the safety and effectiveness of the novel I(f) channel antagonist ivabradine to control heart rate after transplantation. METHODS: Of 316 heart transplant recipients at a single center since 1991, ivabradine was administered in 15 patients, in addition to ß-blockers in 4 patients and contraindication to use of ß-blocker therapy in the others. A prospective follow-up study was conducted to identify possible adverse effects, tolerance, and drug effects on heart rate and control of symptoms. RESULTS: Of the 15 patients, 13 were men; overall mean (SD) patient age was 46 (4.6) years. In all patients, treatment was begun after verification of basal heart rate greater than 100 bpm and after other causes of sinus tachycardia had been ruled out. During follow-up of 1.13 (0.3) years, no substantial adverse effects were observed. It was possible to reach the maximum drug dosage in all patients, achieving a reduction in basal heart rate of 33 (6.2) bpm. All patients reported substantial clinical improvement, and demonstrated an increase in functional class. CONCLUSION: Ivabradine is safe, well tolerated, and effective in heart transplant recipients.

Usefulness of cardio MRI on thrombosis of coronary aneurysm as an infrequent cause of ST-elevation coronary syndrome.

We present an unusual case of thrombosis of coronary aneurysm causing myocardial infarction with ST-elevation in precordial leads. Emergent coronary angiography showed thrombotic occlusion of an aneurysm in the proximal segment of the left anterior descendent coronary artery (LAD). After the administration of tenecteplase, pain and ST-elevation disappeared with no overt complications. Cardiac magnetic resonance imaging (MRI) performed two weeks after admission showed thrombi partially filling the aneurysm together with further information regarding coronary anatomy, as well as a preserved global function even though delayed enhancement of the myocardium was patent throughout the territory irrigated by LAD. This case supports cardio MR usefulness in Kawasaki disease in order not only to depict coronary abnormalities, but also to provide accurate information regarding function and viability in a non-invasive way. It also highlighted the relevance of a proper selection of the sequence technique when thrombus is suspected. All these advantages point out to cardiac MRI as the modality of choice in the follow-up of patients in this clinical scenario.
