Use of oral anticoagulants in complex clinical situations with atrial fibrillation. / Uso de anticoagulantes orales en situaciones clínicas complejas con fibrilación auricular.

The present article provides an update on anticoagulant treatment in patients with atrial fibrillation in distinct clinical scenarios requiring particular considerations, such as ischaemic heart disease, electrical cardioversion, pulmonary vein ablation, the presence of valvular disease with or without prosthetic valves, and renal insufficiency, as well as old age and frailty. In patients with non-valvular atrial fibrillation, the presence of renal insufficiency increases both thrombotic and haemorrhagic risk. In mild and moderate stages, direct-acting anticoagulants confer a greater benefit than warfarin, although they usually require dose adjustment. In renal failure/dialysis, there is no solid evidence that warfarin is beneficial and the use of direct-acting anticoagulants is not recommended. Because of its pathophysiology, oral anticoagulation could have a beneficial effect in patients with heart disease. However, vitamin K antagonists have not shown a satisfactory risk-benefit ratio. In contrast, direct-acting anticoagulants, at reduced doses, could have a beneficial effect in this scenario in association with antiplatelet agents. The use of direct-acting anticoagulants prior to electrical cardioversion in patients with non-valvular atrial fibrillation seems to be associated with a risk of cardioembolic events that is at least comparable to that of vitamin K antagonists. Their use avoids delay in the application of electrical cardioversion in patients without adequate INR levels. In the context of their use before and after atrial fibrillation ablation, dabiga-tran and rivaroxaban have demonstrated at least non-inferiority with vitamin K antagonists in terms of safety. In patients with any type or grade of valvular disease and atrial fibrillation, the indication of antithrombo-tic treatment must be evaluated in the same way as in patients with atrial fibrillation and no valvular di-sease. Whenever anticoagulation is required, direct-acting anticoagulants are the treatment of choice in nearly all situations, except in patients with mechanical valves or who have significant rheumatic mitral disease, who should be treated with vitamin K antagonists. The choice of appropriate antithrombotic stra-tegy in frail elderly patients is complex and involves multiple factors beyond assessment of embolic and haemorrhagic risk. Comprehensive geriatric assessment is essential for an individualised final decision. Moreover, any such decision should be consensus-based and periodically reviewed. Direct-acting anticoa-gulants could be the most beneficial alternative in most elderly patients with non-valvular atrial fibrillation.

Uso de anticoagulantes orales en situaciones clínicas complejas con fibrilación auricular / Use of oral anticoagulants in complex clinical situations with atrial fibrillation

En el presente capítulo se actualiza el tratamiento anticoagulante en pacientes con fibrilación auricular y diferentes situaciones clínicas que requieren consideraciones particulares, como son la cardiopatía isquémica, la cardioversión eléctrica, la ablación de venas pulmonares, la presencia de valvulopatías con o sin prótesis, la insuficiencia renal o la ancianidad y fragilidad. En pacientes con fibrilación auricular no valvular, la presencia de insuficiencia renal incrementa tanto el riesgo trombótico como el hemorrágico. En los estadios leves y moderados, los anticoagulantes de acción directa mostraron un mayor beneficio que warfa-rina, aunque suelen requerir ajuste de dosis. En el estadio de fallo renal/diálisis, no hay evidencia sólida de que la warfarina resulte beneficiosa y la utilización de los anticoagulantes de acción directa no está recomendada. Por su fisiopatología, se ha considerado que la anticoagulación oral podría ejercer un efecto beneficioso en los pacientes con cardiopatía isquémica. Sin embargo, los anticoagulantes antivitamina K no han demostrado una relación riesgo-beneficio satisfactoria. Por el contrario, los anticoagulantes de acción directa, en dosis reducidas, podrían ejercer un efecto beneficioso en este escenario en asociación con los antiagregantes. El uso de los anticoagulantes de acción directa previo a la cardioversión eléctrica en pacientes con fibrila-ción auricular no valvular parece tener asociado un riesgo de eventos cardioembólicos, al menos comparable a los anticoagulantes antivitamina K, evitando la demora en aplicar esta técnica en pacientes sin niveles adecuados de INR precardioversión eléctrica. En el contexto de su uso periablación de fibrilación auricular, el dabigatrán y el rivaroxabán demostraron al menos no inferioridad respecto a los anticoagulantes antivitamina K en cuanto a seguridad. La coexistencia de cualquier tipo y grado de valvulopatías con la fibrilación auricular obliga a evaluar la in-dicación de tratamiento antitrombótico de la misma manera que si no existiera valvulopatía. Cuando sea necesaria la anticoagulación, los anticoagulantes de acción directa son de elección en casi todas las situaciones, excepto en los pacientes portadores de una prótesis mecánica o que padezcan enfermedad mitral reumática significativa, que deben tratarse con anticoagulantes antivitamina K. La elección de la estrategia antitrombótica adecuada en el anciano frágil es una cuestión compleja en que interfieren múltiples factores, más allá de la evaluación del riesgo embólico y hemorrágico. La realización de una evaluación geriátri-ca integral es fundamental para que la decisión final sea individualizada. Además, esta se debe consensuar y revaluar periódicamente. Los anticoagulantes de acción directa podrían ser la alternativa más favorable en la mayoría de los pacientes ancianos con fibrilación auricular no valvular

Management of patients with type 2 diabetes and multiple chronic conditions: A Delphi consensus of the Spanish Society of Internal Medicine.

AIMS: To develop consensus-based recommendations for the management of chronic complex patients with type 2 diabetes mellitus using a two round Delphi technique. METHODS: Experts from the Diabetes and Obesity Working Group (DOWG) of the Spanish Society of Internal Medicine (SEMI) reviewed MEDLINE, PubMed, SCOPUS and Cochrane Library databases up to September 2014 to gather information on organization and health care management, stratification of therapeutic targets and therapeutic approach for glucose control in chronic complex patients with type 2 diabetes mellitus. A list of 6 recommendations was created and rated by a panel of 75 experts from the DOWG by email (first round) and by open discussion (second round). A written document was produced and sent back to DOWG experts for clarification purposes. RESULTS: A high degree of consensus was achieved for all recommendations summarized as 1) there is a need to redesign and test new health care programs for chronic complex patients with type 2 diabetes mellitus; 2) therapeutic targets in patients with short life expectancy should be individualized in accordance to their personal, clinical and social characteristics; 3) patients with chronic complex conditions and type 2 diabetes mellitus should be stratified by hypoglycemia risk; 4) age and specific comorbidities should guide the objectives for glucose control; 5) the risk of hypoglycemia should be a key factor when choosing a treatment; and 6) basal insulin analogs compared to human insulin are cost-effective options. CONCLUSION: The assessment and recommendations provided herein represent our best professional judgment based on current data and clinical experience.

Unanswered clinical questions in the management of cardiometabolic risk in the elderly: a statement of the Spanish Society of Internal Medicine.

BACKGROUND: Despite the progressive increase in life expectancy and the relationship between aging with multi-morbidities and the increased use of healthcare resources, current clinical practice guidelines (CPG) on cardiometabolic risk cannot be adequately applied to elderly subjects with multiple chronic conditions. Its management frequently becomes complicated by both, an excessive use of medications that may lead to overtreatment, drug interactions and increased toxicity, and errors in dosage and non-compliance. Concerned by this gap, the Spanish Society of Internal Medicine created a group of independent experts on cardiometabolic risk who discussed what they considered to be unanswered questions in the management of elderly patients. DISCUSSION: Current guidelines do not specifically address the problem of elderly with multiple chronic conditions. For this reason, the combined use of the limited available evidence, clinical experience and common sense, could all help us to address this unmet need. In very old people, life expectancy and functionality are the most important factors for guiding potential treatments. Their higher propensity to develop serious adverse events and their shorter lifespan could prevent them from obtaining the potential benefits of the interventions administered. SUMMARY: In this document, experts on cardiometabolic risk factors have established a number of consensual recommendations that have taken into account international guidelines and clinical experience, and have also considered the more effective use of healthcare resources. This document is intended to provide general recommendations for clinicians and to promote the effective use of procedures and medications.

[Clinical value of the ankle-brachial index in patients at risk of cardiovascular disease but without known atherothrombotic disease: VITAMIN study]. / Valor de la determinación del índice tobillo-brazo en pacientes de riesgo vascular sin enfermedad aterotrombótica conocida: estudio VITAMIN.

INTRODUCTION AND OBJECTIVES: Detecting peripheral arterial disease by measuring the ankle-brachial index can help identify asymptomatic patients with established disease. We investigated the prevalence of peripheral arterial disease (i.e., an ankle-brachial index <0.9) and its potential clinical and therapeutic impact in patients with no known arterial disease who were seen at internal medicine departments. METHODS: This multicenter, cross-sectional, observational study included patients at risk of cardiovascular disease who were selected on the basis of age, gender and the presence of conventional risk factors. No patient was known to have arterial disease. RESULTS: The study included 493 patients, 174 (35%) of whom had diabetes, while 321 (65%) did not. Only 16% were in a low-risk category according to their Framingham score. An ankle-brachial index <0.9 was observed in 27.4%, comprising 37.9% of those with diabetes and 21.3% of those without. Multiple logistic regression analysis showed that the risk factors associated with an ankle-brachial index <0.9 were age, diabetes, and hypercholesterolemia. There was a significant relationship between the ankle-brachial index and Framingham risk categories. Therapeutically, only 21% of patients with an ankle brachial index <0.9 were taking antiplatelet drugs. Overall, 20% had a low-density lipoprotein cholesterol concentration <100 mg/dl and 52% had a concentration <130 mg/dl. Some 42% had arterial blood pressures below 140/90 mm Hg. CONCLUSIONS: Asymptomatic peripheral arterial disease was detected in a high proportion of patients with an intermediate or high cardiovascular disease risk. The ankle-brachial index should be measured routinely in patients at risk of cardiovascular disease who are seen at internal medicine departments.

Introducción y objetivos. La detección de la enfermedad arterial periférica, mediante el índice tobillo-brazo, permite identificar a los pacientes asintomáticos con una lesión establecida. Investigamos la prevalencia de enfermedad arterial periférica (índice tobillo-brazo < 0,9) en sujetos sin enfermedad arterial conocida atendidos en el ámbito de medicina interna y su potencial impacto clínico-terapéutico. Métodos. Estudio multicéntrico, transversal, observacional en el que se incluyó a pacientes con potencial riesgo cardiovascular, seleccionados en función de la edad, el sexo y la presencia de factores de riesgo convencionales, pero sin enfermedad arterial conocida. Resultados. Se evaluaron 493 casos, de los que 174 eran diabéticos (35%) y 321, no diabéticos (65%). Sólo un 16% presentó un riesgo bajo según la ecuación de Framingham. Del total de la muestra, el índice tobillo-brazo fue < 0,9 en el 27,4% (el 37,9% de los diabéticos y el 21,3%, de los no diabéticos). En el análisis multivariable, los parámetros que se asociaron con un índice tobillo-brazo < 0,9 fueron la edad, la diabetes mellitus y la hipercolesterolemia. Se objetivó una relación significativa entre las categorías de riesgo de Framingham y el índice tobillo-brazo. Al considerar a los pacientes con un índice tobillo-brazo < 0,9, sólo el 21% recibía tratamiento antiagregante, el 20% presentaba valores de colesterol unido a lipoproteínas de baja densidad (LDL) < 100 mg/dl (el 52% con LDL < 130 mg/dl) y el 42% tenía unos valores de presión arterial < 140/90 mmHg. Conclusiones. En una proporción elevada de pacientes con riesgo cardiovascular intermedio o alto se detecta enfermedad arterial periférica asintomática. El índice tobillo-brazo debería medirse sistemáticamente en enfermos con riesgo vascular, evaluados en el ámbito de la medicina interna
