Immunoadsorption Therapy for Patients with Dilated Cardiomyopathy and Heart Failure
Several autoantibodies directed against cardiac cellular proteins including G-protein-linked receptors, contractile proteins and mitochondrial proteins, have been identified in patients with dilated cardiomyopathy (DCM). Among these autoantibodies, anti-beta1-adrenoreceptor (AR) antibodies have long been discussed in terms of their pathogenetic role in DCM. Anti-beta1-AR antibody-positive patie...
متن کاملElectrocardiographic Manifestations of Benzodiazepine Toxicity
Background: The aim of this study was to evaluate and compare the clinical and electrocardiographic (ECG) manifestations of benzodiazepines (BZs). Methods: In this retrospective study, all BZ-poisoned patients hospitalized at Loghman Hakim Hospital between September 2010 and March 2011 were evaluated. Patients’ information including age, sex, time elapsed between the ingestion and presenta...
متن کاملProlongation of the QT interval in heart failure occurs at low but not at high heart rates.
Abnormal left ventricular structure and function as in, for example, left ventricular hypertrophy or chronic heart failure, is associated with sudden cardiac death and, when the ejection fraction is depressed, with prolongation of the QT interval. The dependence on heart rate of QT interval prolongation in these conditions, and the relationship of any abnormalities either to deranged autonomic ...
متن کاملFailure of atrial natriuretic factor to increase with saline load in patients with dilated cardiomyopathy and mild heart failure.
To investigate whether the response of atrial natriuretic factor (ANF) to volume expansion is impaired in the early stages of dilated cardiomyopathy, the effects of saline load (SL; 0.25 ml/kg.min for 120 min) were assessed in 12 patients with dilated cardiomyopathy and asymptomatic to mildly symptomatic heart failure (HF) and in nine normal subjects (N). SL increased plasma ANF levels in N (fr...
متن کاملMechanical Dyssynchrony Precedes QRS Widening in ATP‐Sensitive K+ Channel–Deficient Dilated Cardiomyopathy
BACKGROUND Contractile discordance exacerbates cardiac dysfunction, aggravating heart failure outcome. Dissecting the genesis of mechanical dyssynchrony would enable an early diagnosis before advanced disease. METHODS AND RESULTS High-resolution speckle-tracking echocardiography was applied in a knockout murine surrogate of adult-onset human cardiomyopathy caused by mutations in cardioprotect...
