Abstract Background Several reports have described Takotsubo syndrome (TTS) secondary to thyrotoxicosis. A complex interaction of central and peripheral catecholamines with thyroid homeostasis has been suggested. In this study, we analysed sequential hormone profiles during the acute phase TTS. Methods Thyrotropin (TSH), free T4 (FT4) T3 (FT3) concentrations were at predefined time points in 32 patients presenting TTS or coronary (ACS, n = 16 each group) a 2‐year period two German university...
Recently, abnormal thyroid function was shown to be common in patients with Takotsubo syndrome (TTS), being classified into "endocrine-type" and "stress-type" responses. The aim of this study investigate the association between homeostasis TTS a larger international registry.
Abstract Data on the use of wearable cardioverter defibrillator (WCD) among patients after cardiac implantable electronic device explantation 1- to 3-chamber systems (ICD) are sparse.

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is associated with arrhythmic events which may lead to sudden cardiac death (SCD). A leading therapy for CPVT besides medical treatment beta-blockers the use of an implantable cardioverter-defibrillator (ICD). For this paper we compared data from a pooled analysis get further evidence about complications transvenous and subcutaneous ICDs. We gathered search PubMed, Web Science, Cochrane Library Cinahl. our analysis, chose 30...
Background: Cephalic vein cutdown (CVC) and subclavian puncture (SVP) are the most commonly used access sites for transvenous lead placement of cardiac implantable electronic devices (CIEDs). Limited knowledge exists about long-term patency vascular lumen housing leads. Methods: Among 2703 patients who underwent CIED procedures between 2005 2013, we evaluated phlebographies 162 scheduled an elective replacement (median 6.4 years after first operation). The were divided into four stenosis...
Fever is a potential side effect of the Covid-19 vaccination. Patients with Brugada syndrome (BrS) have an increased risk life-threatening arrhythmias when experiencing fever.
