How the Apple Watch Could Change How We Treat Heart Disease
The new Apple Watch Series 3 gives users more real-time information about their heart than ever, and Apple hopes that it will also be able to alert users to potentially concerning heart beat patterns.
The current version of the Apple Watch already tracks heart rate. But the newest version comes with cellular built in, which means it can record heart rate continuously anywhere you have service. That could provide valuable, instantly accessible data for detecting when things might be awry with your heart—if it’s racing too fast when you’re at rest, for example. You can also set the monitor to alert you if y...

Integrated Machine Learning Approaches for Predicting Ischemic Stroke and Thromboembolism in Atrial Fibrillation.
In this study, we used integrated machine learning and data mining approaches to build 2-year TE prediction models for AF from Chinese Atrial Fibrillation Registry data. We first performed data cleansing and imputation on the raw data to generate available dataset. Then a series of feature construction and selection methods were used to identify predictive risk factors, based on which supervised learning methods were applied to build the prediction models. The experimental results show that our approach can achieve higher prediction performance (AUC: 0.71~0.74) than previous TE prediction models for AF (AUC: 0.66~0.69), an...

Neurologic Complications of Cardiac and Aortic Disease
This article discusses neurologic complications that can arise from cardiac and aortic disease and dysfunction.
Recent Findings: Advances in the care of patients with cardiac or aortic disease include the use of prolonged cardiac monitoring in cryptogenic stroke and the approval of the use of left atrial appendage closure devices for stroke prevention in patients with atrial fibrillation who are not candidates for anticoagulation. Continuing controversy surrounds patent foramen ovale closure, and new evidence indicates that cognitive impairment following coronary artery bypass grafting surgery may be less common than prev...

Non-Vitamin K Oral Anticoagulants for Stroke Prevention in Special Populations with Atrial Fibrillation
AbstractAtrial fibrillation (AF) is associated with an increased risk of ischemic stroke or systemic embolism compared with normal sinus rhythm. These strokes may efficiently be prevented in patients with risk factors using oral anticoagulant therapy, with either vitamin K antagonists (VKAs) or non-vitamin K antagonist oral anticoagulants (NOACs) (i.e., direct thrombin inhibitors or direct factor Xa inhibitors). Owing to their specific risk profiles, some AF populations may have increased risks of both thromboembolic and bleeding events. These AF patients may be denied oral anticoagulants, whilst evidence shows that the ab...

Mid-Term Follow-up of Minimally Invasive Multivessel Coronary Artery Bypass Grafting: Is the Early Learning Phase Detrimental?
Conclusions: Minimally invasive coronary artery bypass grafting can be safely initiated as a minimally invasive, multivessel alternative to open surgical coronary revascularization, with excellent mid-term results. Learning phase effects were not observed with regard to overall procedural safety, but rather in terms of improved freedom from conversion to sternotomy and from repeat revascularization.

Diagnosis and Management of Transient Ischemic Attack
This article reviews the diagnosis, investigation, and recommended management after a transient ischemic attack (TIA) and discusses how to make an accurate diagnosis, including the diagnosis of mimics of TIAs.
Recent Findings: Up to a 10% risk of recurrent stroke exists after a TIA, and up to 80% of this risk is preventable with urgent assessment and treatment. Imaging of the brain and intracranial and extracranial blood vessels using CT, CT angiography, carotid Doppler ultrasound, and MRI is an important part of the diagnostic assessment. Treatment options include anticoagulation for atrial fibrillation, carotid revascul...

Cardioembolic Stroke
This article summarizes the different causes of cardioembolism and outlines current management guidelines.
Recent Findings: Since cardioembolic stroke is not a single disease entity, its diagnosis requires initial clinical suspicion and a comprehensive evaluation, including ECG, echocardiography, brain imaging, and cardiac monitoring. Atrial fibrillation is the most common cause of cardioembolic stroke, and anticoagulation is usually recommended. This article reviews risk stratification models to assist in the decision-making process and highlights the increased use of novel oral anticoagulants for stroke prevention in at...

Are You Getting Older - Or Are You Getting Sleep Apnea?
By Brandon R. Peters, MD
As my 81-year-old grandma likes to remind me on occasion, "It's hell to get old." More than a nuisance, the cumulative decline that comes with aging can significantly compromise one's quality of life and health. What if some of the problems so often associated with growing older didn't need to occur? Better yet, what if some of these physical and mental impairments could be reversed? Consider the role of sleep apnea as an unexpected contributor to many ailments erroneously attributed to aging and the reversals possible with effective treatment.

It is clear that sleep chang...

Quality Improvement in Acute Ischemic Stroke Care in Taiwan: The Breakthrough Collaborative in Stroke

In the management of acute ischemic stroke, guideline adherence is often suboptimal, particularly for intravenous thrombolysis or anticoagulation for atrial fibrillation. We sought to improve stroke care quality via a collaborative model, the Breakthrough Series (BTS)-Stroke activity, in a nationw ide, multi-center activity in Taiwan. A BTS Collaborative, a short-term learning system fo...

'Dying of heartache?' Heart problems linked to bereavement
Conclusion
The study found that people were more likely to have AF for the first time in the weeks immediately after a bereavement, but that this raised risk does not last. Despite the headlines, this does not mean that anyone who's had a bereavement is at immediate risk of "dying of a broken heart". Atrial fibrillation is treatable and not usually life-threatening.
Because this was an observational study, we cannot rule out the possibility that factors such as family history of atrial fibrillation or lifestyle factors could have affected the results, although the researcher's conclusion that this is a small poss...

A Case of Transient Global Amnesia: A Review and How It May Shed Further Insight into the Neurobiology of Delusions
Conclusion
In closing, our patient’s episode of TGA combined with her emotional and perceptual response lends credence to the proposal of a “fear/paranoia” circuit in the genesis of paranoid delusions—a circuit incorporating amygdala, frontal, and parietal cortices. Here, neutral or irrelevant stimuli, thoughts, and percepts come to engender fear and anxiety, while dysfunction in frontoparietal circuitry engenders inappropriate social predictions and maladaptive inferences about the intentions of others.[54]
Hippocampus relays information about contextual information based on past experiences and the current situat...

Biotronik launches trial of CLS AF algorithm
Biotronik said today it enrolled the 1st patient in its B3 trial examining the company’s Closed Loop Stimulation physiologic rate response sensor and algorithm.
The study aims to whether pacemakers and implantable cardioverter-defibrillators equipped with the CLS sensor and algorithm are able to reduce the rate of stroke and improve outcomes in patients with atrial fibrillation compared to those without the system.
“AF is a huge clinical challenge, affecting over 20 million patients in Europe and the US alone. I am very excited to begin this groundbreaking trial. We hope to demonstrate that the physiological h...
