Arrhythmia News and Research

RSS

An arrhythmia is a problem with the speed or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. A heartbeat that is too fast is called tachycardia. A heartbeat that is too slow is called bradycardia. Most arrhythmias are harmless, but some can be serious or even life threatening. When the heart rate is too slow, too fast, or irregular, the heart may not be able to pump enough blood to the body. Lack of blood flow can damage the brain, heart, and other organs.

Pharmacotherapy reduces conduction system disease risk

Lisinopril therapy significantly reduces incident conduction system disease, indicates a post-hoc analysis of ALLHAT data.

Scientists develop novel bionic cardiac patch to treat heart problems

Scientists and doctors in recent decades have made vast leaps in the treatment of cardiac problems - particularly with the development in recent years of so-called "cardiac patches," swaths of engineered heart tissue that can replace heart muscle damaged during a heart attack.

Mathematical model helps investigate mechanisms involved in genesis of AF-related dementia

Atrial fibrillation (AF), the most common cardiac arrhythmia, turns out to be a potential mechanism into the genesis of AF-related cognitive impairment/dementia.

Race impacts adverse outcomes in atrial fibrillation

Black individuals with atrial fibrillation have markedly higher rates of stroke, heart failure, coronary heart disease and mortality than their White counterparts, data from the Atherosclerosis Risk in Communities study show.

Genetic testing worthwhile in sudden cardiac death

Genetic testing and family screening help to provide explanations for sudden cardiac death in children and young adults, shows a population-based study.

Could artificial intelligence help to combat stress? An interview with Davide Morelli

Stress is actually a bit of a buzzword. The initial definition was “the reaction to changes”, which is why you get stressed also when good things happen, hence the distinction between good stress, eustress, and bad stress, distress.

NOACs match warfarin for atrial fibrillation

Real-world study data from Denmark show that non-vitamin K antagonist oral anticoagulants are effective alternatives to warfarin in patients with non-valvular atrial fibrillation in a routine care setting.

AF patients at risk for stroke mostly treated with aspirin-only prescription instead of blood thinners

Researchers at University of California San Diego School of Medicine and University of California, San Francisco School of Medicine report that more than 1 in 3 atrial fibrillation (AF) patients at intermediate to high risk for stroke are treated with aspirin alone, despite previous data showing this therapy to be inferior to blood thinners.

Apixaban effective in polypharmacy setting

The superiority of apixaban over warfarin in patients with atrial fibrillation is maintained in those taking multiple medications, shows further analysis of the ARISTOTLE trial.

Worsening renal function linked to increased cardiovascular risk in AF

Patients with atrial fibrillation and declining renal function are at increased risk of subsequent stroke or systemic embolism, major bleeding and death, US researchers report.

Watchman device for irregular heart rhythms may be preferable to standard blood thinning medications

A new study by a Yale researcher may support the use of a device for patients suffering from irregular heart rhythms.

Researchers clarify cause of heart arrhythmia in myotonic dystrophy

An international joint research group found that the cause of heart arrhythmia in myotonic dystrophy was RNA abnormalities in the sodium channel in the heart, clarifying the symptom's mechanism. This finding will be helpful in prevention and early intervention of death in this disease, leading to the development of new treatment.

Study evaluates effectiveness of robotic approach over manual ablation in treating heart arrhythmia

Whether ablation of the highest-risk heart arrhythmia is best handled by a robot or the hands of an electrophysiologist should be answered by an international comparison of the two.

Consensus paper on atrial cardiomyopathies could be important step forward for research, treatment

The first consensus paper on atrial cardiomyopathies is set to be published simultaneously in EP-Europace, HeartRhythm, and the Journal of Arrhythmia. The key contents are launched today at CARDIOSTIM - EHRA EUROPACE 2016.

Women more likely to be hospitalised for acute ischaemic stroke than men, say researchers

A 15 year study in 1.1 million patients with atrial fibrillation has found that women are 23% more likely to be hospitalised for acute ischaemic stroke than men. The research was presented today at CARDIOSTIM - EHRA EUROPACE 2016 by Dr Ghanshyam Shantha, a cardiovascular disease fellow at the University of Iowa Hospitals and Clinics, Iowa City, Iowa, US.

CMR could offer complete imaging solution before pulmonary vein isolation

Cardiac magnetic resonance can potentially be used to detect thrombi at the same time as being used for pulmonary venous anatomy mapping, say researchers

Just one stroke risk factor signals anticoagulation need in AF

The risk of stroke or systemic embolism is significantly increased in atrial fibrillation patients with just one risk factor apart from gender, say researchers.

2 Jun 2016

Trial results underestimate anticoagulant bleeding risk

A study in The BMJ demonstrates that estimates of major bleeding risk in patients taking anticoagulants in clinical trials are unlikely to reflect the reality of clinical practice.

Study finds link between respiratory sinus arrhythmia and survival prospects of heart attack patients

The heart rate may be an indicator of a person's life expectancy. A research team at the Technical University of Munich has to this end analyzed an effect which at first seems paradoxical: Minor irregularities in the heartbeat are indicative of a healthy body.

AF linked to increased cancer risk in women

Women with new-onset atrial fibrillation have a significantly increased cancer risk for at least 1 year after AF diagnosis, an analysis of Women's Health Study data shows.
