The previous use of digoxin does not worsen early outcome of acute coronary syndromes: an analysis of the ARIAM Registry.

The aim of the study was to determine the influence of the previous use of digoxin on the hospital mortality and complications of patients admitted because of acute coronary syndrome (ACS). We analyzed the data of patients included in the ARIAM-Andalucia Registry, which involves 49 hospitals in Andalucia, Spain, from 2007 to 2012. Patients on digoxin treatment prior to their admission because of ACS constituted the digoxin group (DG), and were compared with the group of patients not on digoxin. Logistic regression and propensity score matching were used to analyze the differences. We included 20,331 patients, of whom 244 (1.2%) were on digoxin. DG patients were older (73.1 vs 63.7 years old), more often women, and had more diabetes, hypertension, previous myocardial infarction, heart failure, stroke, atrial fibrillation, peripheral vascular disease, obstructive pulmonary disease or kidney disease. On univariate analysis, DG patients had significantly higher hospital mortality (13.5 vs 5.3% P < 0.001), and more cardiogenic shock, but less ventricular fibrillation, and no differences in atrioventricular block, stroke or reinfarction. After the multivariate analysis, DG had no significant influence on hospital prognosis [odds ratio (OR) 1.21, 95% confidence interval 0.79-1.86]. The analysis of a propensity-matched cohort of 464 patients (232 DG and 232 NoDG) did not find differences in hospital mortality (13.4 vs 13.4%) nor other complications. In our cohort of ACS patients, the previous treatment with digoxin was not associated with an increase in dysrhythmic complications nor was an independent predictor of mortality during hospitalization.

Functional anatomy of aortic regurgitation. Role of transesophageal echocardiography in aortic valve-sparing surgery.

INTRODUCTION AND OBJECTIVES: The aim was to evaluate the usefulness of transesophageal echocardiography (TEE) for the preoperative functional anatomical assessment of patients with aortic regurgitation (AR) to identify those eligible for valve-sparing surgery (VSS). METHODS: We determined the accuracy and diagnostic value of TEE for identifying underlying lesions and mechanisms in 66 patients who underwent surgery for severe AR by comparing TEE findings with those obtained on surgical inspection. The usefulness of TEE for predicting the feasibility of VSS was determined. RESULTS: The overall diagnostic accuracy of TEE was excellent (87%, kappa=0.82), with valve prolapse being the principle cause of discrepancy between the methods (in 23/27 cases; 85%). Three anatomical forms of dilatation of the ascending aorta (AA) were correctly classified (accuracy >88%; kappa 0.83): supratubal aneurysm (19 patients), aortic root aneurysm (4), and annuloaortic ectasia (24). The mechanism underlying AR was identified with an accuracy of 85% (kappa 0.8) and there was a significant association between the type of mechanism identified by TEE and the success of VSS (P< .001): VSS was successful in 73% of patients with dilatation of a functional annulus (i.e. with tethering), but aortic valve replacement was required in 78% with prolapses, 90% with thickened leaflets with restricted movement, and 100% with perforation. There was also a relationship between the type of aneurysm and the technique required for AA replacement (P=.004). CONCLUSIONS: Use of TEE enabled the mechanism underlying AR to be accurately identified. There was a high level of agreement with surgical inspection and the technique was useful for predicting the feasibility of VSS and the surgical procedure for AA replacement.

Anatomía funcional de la insuficiencia aórtica. Papel de la ecocardiografía transesofágica en la cirugía conservadora de válvula aórtica / Functional anatomy of aortic regurgitation. Role of transesophageal echocardiography in aortic valve-sparing surgery

Introducción y objetivos. Intentamos determinar el papel de la ecocardiografía transesofágica (ETE) en la descripción preoperatoria de la anatomía funcional de la insuficiencia aórtica (IAo) para identificar candidatos a cirugía conservadora (CCVAo). Métodos. En 66 pacientes intervenidos de IAo severa se determinan precisión y valores diagnósticos de la ETE en la descripción de lesiones y mecanismos, empleando la observación quirúrgica como referencia. Se valora la utilidad de la ETE para predecir aplicabilidad de técnicas de CCVAo. Resultados. La exactitud diagnóstica general de la ETE es excelente (87%, índice kappa = 0,82); el prolapso presenta la principal discrepancia (23/27 casos; 85%) entre los métodos. Tres formas anatómicas de dilatación de aorta ascendente (AA) fueron correctamente clasificadas (precisión, > 88%; kappa = 0,83): aneurisma de AA supratubular (19), aneurisma de raíz (4) o anuloectasia aórtica (24). La precisión en el diagnóstico del mecanismo fue del 85% (kappa = 0,8) y éste presentó una asociación significativa con el éxito de la CCVAo (p < 0,001) en el 73% de los casos de dilatación de los anillos funcionales (tethering). El 78% de prolapsos, el 90% de movimiento restrictivo de velos engrosados y el 100% de perforaciones requirieron sustitución valvular aórtica. Las formas de aneurisma también se relacionaron con el procedimiento de sustitución de AA (p = 0,004). Conclusiones. La ETE permite una descripción precisa de los mecanismos de la IAo, tiene una elevada tasa de acuerdo con las observaciones quirúrgicas y predice adecuadamente la aplicabilidad de la CCVAo y el procedimiento de sustitución de AA (AU)

Guías de práctica clínica de la Sociedad Española de Cardiología en la gestante con cardiopatía / Guidelines of the Spanish Society of Cardiology for the management of cardiovascular diseases during pregnancy

Durante la gestación normal se producen cambios hormonales, se establece la circulación uteroplacentaria, se incrementa el volumen plasmático, disminuyen las resistencias vasculares periféricas y se producen modificaciones que favorecen la hipercoagulabilidad. Todo ello favorece la aparición de semiología cardiovascular, haciendo que el diagnóstico diferencial con la existencia de cardiopatía subyacente sea a la vez fundamental y complejo. Además, estos cambios fisiológicos aumentan el riesgo de complicaciones maternofetales en las mujeres con cardiopatía. Se considera que la cardiopatía en el embarazo es la primera causa de morbimortalidad materna de causa no obstétrica. Las cardiopatías reumática y congénitas son, hoy día, las más frecuentes en la mujer embarazada, seguidas por la hipertensión arterial, la cardiopatía isquémica y las arritmias. En general, la enfermedad cardíaca tiende a empeorar con el tiempo, por lo que las mujeres con cualquier tipo de cardiopatía que deseen tener niños deberían hacerlo lo antes posible. La mayoría de las pacientes con cardiopatía no tienen problemas para llevar a término un embarazo. Las excepciones a esta regla son las pacientes en grado funcional III-IV con severo compromiso de la función cardíaca, la hipertensión pulmonar de cualquier origen, las cardiopatías congénitas con cianosis y grado funcional IIIIV, el síndrome de Marfan, las lesiones obstructivas izquierdas severas sintomáticas o asintomáticas con datos de disfunción sistólica, las portadoras de válvulas cardíacas artificiales y las mujeres con antecedentes de miocardiopatía asociada al embarazo, en las cuales debe desaconsejarse el embarazo o, en caso de producirse, puede recomendarse su interrupción, asumiendo los problemas éticos que se generan a la embarazada y al médico. Las cardiopatías más graves conllevan una elevada incidencia de aborto espontáneo, y en las cardiopatías congénitas debe valorarse el riesgo asociado de herencia. La intervención médica debe iniciarse precozmente, antes de la concepción, incluyendo la información respecto a las posibles repercusiones sobre la cardiopatía materna y el feto (AU)
