REVIEW
Ralph Bosch, Ingrid Mutscher
Remote follow-up of patients with implantable electronic cardiac devices (IECD) is a scientifically well-evaluated and technically mature method. Advantages over conventional follow-up include rapid detection of clinically relevant events (i. e. arrhythmias) and of technical problems. Additionally, telemetric follow-up of IECDs has a high degree of acceptance among both patients as well as health care professionals and carries the potential to reduce health care costs. The implementation of a remote follow-up programme is associated with organisational, infrastructural and legal aspects, which are reviewed...

Atrial fibrillation (AF) is the most common cardiac arrhythmia worldwide with an estimated number of 2.7-6.1 million cases in the United States (US) alone. The incidence of AF is expected to increase 2.5 fold over the next 50 years in the US. The management of AF is complex and includes mainly three aspects; restoration of sinus rhythm, control of ventricular rate and prevention of systemic thromboembolism. AF as a cause of systemic embolization has been well known for many years, and majority of patients are on oral anticoagulants (OACs) to prevent this...

Myocardial ischemia/reperfusion (MIR) injury causes severe arrhythmias and a high lethality. The present study is designed to investigate the effect of cilostazol on MIR injury and the underlying mechaism. We measured the effects of cilostazol on heart function parameters in a mouse model of MIR. Proinflammatory cytokines and apoptosis proteins in the myocardium were examined to investigate the anti-inflammatory and anti-apoptosis ability of cilostazol. The participation of PPARγ/JAK2/STAT3 pathway was investigated...

BACKGROUND: Women have a higher risk of lethal arrhythmias than men in long QT syndrome type 2 (LQTS2), but the mechanisms remain uncertain due to the limited availability of healthy control human tissue. We have previously reported that in female rabbits, estrogen increases arrhythmia risk in drug-induced LQTS2 by upregulating L-type Ca(2+) (ICa,L) and sodium-calcium exchange (INCX) currents at the base of the epicardium by a genomic mechanism. This study investigates if the effects of estrogen on rabbit ICa,L and INCX apply to human hearts...

Hypokalemia (ie, potassium levels less than 3.5 mEq/L) occurs in fewer than 1% of healthy individuals, but is present in up to 20% of hospitalized patients, 40% of patients taking diuretics, and 17% of patients with cardiovascular conditions. Hypokalemia often is asymptomatic; symptoms are more common in older adults. Common symptoms are cardiac arrhythmias and muscle weakness or pain. Management consists of intravenous potassium replacement during cardiac monitoring for patients with marked symptoms, echocardiogram (ECG) abnormalities, or severe hypokalemia (ie, level less than 3...

Type 2 diabetes is associated with higher rate of ventricular arrhythmias and this is hypothesised to be independent of coronary artery disease or hypertension. To investigate further we compared changes in left ventricular myocardial gene expression in Type 2 diabetes to patients in a control group with left ventricular hypertrophy. 9 control patients and 7 patients with type 2 diabetes with aortic stenosis undergoing aortic valve replacement had standard ECGs, signal averaged ECGs and echocardiograms prior to surgery...

Cardiovascular affections are a growing health burden in human populations. Recent advances in cardiology have improved treatments and outcomes for myocardial infarction and arrhythmias, but other conditions still remain poorly understood. To date, the classical approach to study cardiovascular diseases involves rodent models, despite their strong differences with human cardiac physiology. In this context, this review will focus on the common traits between human and feline cardiac diseases, namely heart failure with preserved ejection fraction and feline cardiomyopathies, respectively...

Hypokalemia has been consistently reported as a common occurrence during targeted temperature management (TTM) in comatose survivors of cardiac arrest. We sought to better describe changes in serum potassium throughout the different stages of TTM and to assess for any prognostic significance. We analyzed a prospectively collected cohort of 240 patients treated with TTM following cardiac arrest at a tertiary care hospital between 2007 and 2014. The primary outcome was poor neurologic outcome at hospital discharge, defined as a Cerebral Performance Category score >2...

Broken heart syndrome, also known as takotsubo cardiomyopathy, is a syndrome characterized by a transient regional systolic dysfunction of the left ventricle associated to a psychological stress. We herein describe a case of a 23-year-old female habitual marijuana user who was resuscitated after cardiac arrest and then diagnosed with midventricular stress cardiomyopathy complicated by subendocardial hemorrhage. We discuss this unique pathological finding, the incidence of arrhythmias in this syndrome, and the possible relation with chronic cannabis and tobacco use...

Hyperglycemia is an independent risk factor for diabetic cardiomyopathy in humans; however, the underlying mechanisms have not been thoroughly elucidated. Zebrafish (Danio rerio) was used in this study as a novel vertebrate model to explore the signaling pathways of human adult cardiomyopathy. Hyperglycemia was induced by alternately immersing adult zebrafish in a glucose solution or water. The hyperglycemic fish gradually exhibited some hallmarks of cardiomyopathy such as myocardial hypertrophy and apoptosis, myofibril loss, fetal gene reactivation, and severe arrhythmia...

Since the 1990s, when numerous non-cardiac drugs were first recognized to have the potential to prolong the QT interval and cause torsades de pointes (TdP), clinicians, drug regulators, drug developers, and clinical investigators have become aware of the complexities of assessing evidence and determining TdP causality for the many drugs being marketed or under development. To facilitate better understanding, the Arizona Center for Education and Research on Therapeutics, known as AZCERT, has developed the CredibleMeds...

BACKGROUND: Atrial fibrillation (AF) is a type of cardiac arrhythmia which is commonly seen following lung resection. There is currently no algorithm which can predict which patients will develop postoperative AF (PAF). The present study aims to identify the risk factors for the development of PAF and high-risk patients with PAF along with multiple risk factors. MATERIALS AND METHODS: A total of 887 patients, who underwent lung resection due to primary lung malignancy at our clinic between January 2000 and December 2016, were retrospectively analysed...

#18
REVIEW
Akiko Kojima, Hiroshi Matsuura
Although various general anaesthetics affect the heart rate in clinical settings, their precise mechanisms remain to be fully elucidated. Because the heart rate is determined by automaticity of the cardiac pacemaker sinoatrial node and its regulation by autonomic nervous system, it is important to clarify the effect of anaesthetics on sinoatrial node automaticity. The spontaneous electrical activity of sinoatrial node is generated by a complex but coordinated interaction of multiple ionic currents, such as the hyperpolarisation-activated cation current (If), T-type and L-type Ca(2+) currents (ICa,T and ICa,L), Na(+)/Ca(2+) exchange current (INCX), and rapidly and slowly activating delayed rectifier K(+) currents (IKr and IKs)...

Many drugs used for non-cardiovascular and cardiovascular purposes, such as sotalol, have the side effect of prolonging cardiac repolarization, which can trigger life-threatening cardiac arrhythmias by inhibiting the potassium-channel IKr (KCNH2). On the electrocardiogram (ECG), IKr inhibition induces an increase in QTc and Tpeak-Tend (TpTe) interval and a decrease of T wave maximal amplitude (TAmp). These changes vary markedly between subjects, suggesting the existence of predisposing genetic factors. 990 healthy individuals, prospectively challenged with an oral 80mg sotalol dose, were monitored for changes in ventricular repolarization on ECG between baseline and 3 hours post dosing...

BACKGROUND: Atrial fibrillation (AF) burden and duration are predictors of thromboembolic events. The random nature of these measures may affect clinical decision making. The objective of this study was to determine temporal changes in AF burden as detected by continuous monitoring. HYPOTHESIS: AF burden changes over time when detected by continuous monitoring. METHODS: A post hoc analysis of patients enrolled in the TRENDS (A Prospective Study of the Clinical Significance of Atrial Arrhythmias Detected by Implanted Device Diagnostics) study with ≥1 stroke risk factor(s) who were implanted with a dual-chamber cardiac rhythm management device (CRMD) and had AF burden data available for ≥2 years was performed...
