INTRODUCTIONnAnemia has been shown to be associated with a worse prognosis, especially higher mortality in various pathological conditions. However, few studies have specifically examined its impact in acute coronary syndrome (ACS) patients. The purpose of our study was to assess the association between different quartiles of hemoglobin on admission and short- and long-term prognosis in patients with ACS.nnnMETHODSnWe performed a retrospective analysis of 1303 consecutive ACS patients admitted to a coronary care unit and analyzed the association between baseline hemoglobin and morbidity and mortality, in-hospital and at 12-month follow-up. The population was divided into groups according to quartiles of hemoglobin concentration (Hb): Q1: <10.8g/dl; Q2: 10.8-12.2g/dl; Q3: 12.3-13.2g/dl; Q4: ≥13.3g/dl. Logistic regression analysis was used to identify independent predictors of short- and long-term mortality.nnnRESULTSnHypertension and diabetes mellitus were more common in the lower Hb quartiles, while the prevalence of smoking and physical inactivity increased with higher Hb. A higher proportion of patients in the lower quartiles had congestive heart failure, peripheral artery disease and previous stroke or transient ischemic attack. Anemic patients tended to be older, with worse renal function and left ventricular systolic function. Patients in Q1 had significantly higher levels of troponin I and blood glucose on admission. Anemic patients showed significantly higher in-hospital mortality (Q1: 9.8%; Q2: 6.3%; Q3: 4.1%; Q4: 3.6%, p<0.001), longer hospital stay (Q1: 6.1±4.4; Q2: 5.2±3.0; Q3: 4.9±2.7; Q4 4.3±2.1 days, p<0.001) and higher 1-year mortality (Q1: 23.6%; Q2: 11.6%; Q3: 10.6%; Q4: 5.5%, p<0.001). In multivariate analysis, the only independent predictor of in-hospital mortality was Killip class >1 at admission. The independent predictors of long-term mortality were age ≥69.5 years, Killip class >1 at admission, diabetes mellitus, ST-segment depression on admission ECG and Hb <10.8g/dl.nnnDISCUSSION AND CONCLUSIONSnLow baseline hemoglobin is associated with more comorbidities and can accurately predict 1-year mortality after an acute coronary syndrome.

Introduction nPrevious follow-up studies of patients with symptoms and/or non-invasive tests suggestive of ischemia or an acute coronary syndrome and a normal coronary angiogram have reported a good prognosis.

INTRODUCTION AND OBJECTIVESnCardioembolism is one of the most common causes of ischemic stroke, with an estimated prevalence of 20-30%, and correct diagnosis is essential given the therapeutic implications. Although stroke risk scores (CHADS2 and more recently CHA2DS2-VASc) have been validated in heterogeneous populations of patients with atrial fibrillation, their accuracy has not been ascertained for secondary stroke prevention. We set out to assess the sensitivity and specificity of the CHADS2 and CHA2DS2-VASc stroke risk scores as predictors of cardioembolic sources, documented by transesophageal echocardiography (TEE) in a population with ischemic stroke.nnnMETHODSnThe CHADS2 and CHA2DS2-VASc scores were applied to all patients admitted to the stroke unit/neurology ward of a Portuguese tertiary hospital with atrial fibrillation (diagnosed previously or during or after admission) who underwent TEE between January and August 2011. The presence of a cardioembolic source was defined as the observation by TEE of spontaneous echo contrast in the left atrium and atrial appendage or thrombi in the left cardiac chambers.nnnRESULTSnWe studied 94 patients, 66.0% male, mean age 64.4 years (standard deviation 14.2). A cardioembolic source was detected in 20 patients. ROC curve analysis identified as predictors of cardioembolic source CHADS2 score ≥4 (sensitivity of 75.0%, specificity of 66.0%, p=0.014) and CHA2DS2-VASc score ≥5 (sensitivity of 83.3%, specificity of 58.0%, p=0.009).nnnCONCLUSIONSnBoth scores showed acceptable sensitivity as predictors of embolic risk in the context of secondary prevention of cardioembolic stroke. The CHA2DS2-VASc score has higher sensitivity than CHADS2 but lower specificity.

Emery-Dreifuss muscular dystrophy type 1 (EDMD1) is a familial disease with X-Linked recessive transmission, caused by a mutation in a nuclear envelope protein, emerin. Clinical manifestations usually occur in adolescence and include contractures, muscle atrophy and weakness, and cardiac conduction disturbances. We describe the case of a young male, aged 16, with first-degree atrioventricular (AV) block and limited extension of both forearms. He had elevated CK, and cardiac monitoring showed severe conduction tissue disease, with significant sinus pauses, chronotropic incompetence and periods of AV dissociation during exercise. Immunohistochemical staining using an emerin antibody showed absence of the protein in a fragment of muscle tissue and genetic study identified a mutation associated with EDMD1. Study of his brother, aged 21, also established a diagnosis of EDMD1. Both individuals received a permanent pacemaker but musculoskeletal manifestations at that time did not warrant any other intervention: Screening for certain genetic diseases, including muscular dystrophies, is mandatory following identification of conduction abnormalities in young people.
