Here ’s How Well the Apple Watch Can Detect Heart Problems

It’s one of the goals of digital medicine: you wear a device on your wrist that constantly monitors aspects of your health, and if anything is off, it sends you an alert. That’s your cue to connect with your doctor or get a more thorough checkup to head off any potentially serious problems down the road. That’s the idea behind the Heart app on the Apple Watch, which can monitor heart pulse patterns, and detect abnormalities, which could indicate a condition called atrial fibrillation, or AFib. The irregular heart beats characteristic of AFib could lead to stroke, blood clots and heart failure. Researchers at Stanford University have been working with Apple to study how accurately the tech giant’s app could detect AFib in a general population. Early results of the research project, known as the Apple Heart Study, were presented at the annual meeting of the American College of Cardiology last spring. Now, in a paper published Nov. 13 in the New England Journal of Medicine, they report that the app’s alerts matched up with electrocardiography, or ECG readings (the gold standard for detecting atrial fibrillation) 84% of the time. In the NEJM study, the scientists reported results from nearly 420,000 people who already owned Apple Watches and volunteered to participate. Over a period of nearly four days, the watch notified 0.5% of this group of potential abnormal heart rhythms. These people were then asked to contact the study team, which sent them E...

Existing screening methods require prolonged monitoring and are limited by cost and low yield. We aimed to develop a rapid, inexpensive, point-of-care means of identifying patients with atrial ...

Conclusion: These findings limit the possible roles of gene transcriptional changes in previously reported age-dependent pro-arrhythmic electrophysiologial changes observed in Pgc-1β-/- atria to an altered Ca2+-ATPase (Atp2a2) expression. This directly parallels previously reported arrhythmic mechanism associated with p21-activated kinase type 1 deficiency. This could add to contributions from the direct physiological outcomes of mitochondrial dysfunction, whether through reactive oxygen species (ROS) production or altered Ca2+ homeostasis. Introduction Atrial arrhythmias constitute a major public health probl...

This study aimed at describing the clinical features and outcome of AF patients at a tertiary hospital in Botswana. METHODS: This prospective study was carried out in the Princess Marina Hospital in Gaborone, Botswana between August 2016 and July 2018. We consecutively enrolled 138 (97.8% black Africans) adult patients with electrocardiographically documented AF. Their baseline clinical and biomedical data were documented, and each patient was followed up for 12 months. The primary study outcome was 12-month all-cause mortality. RESULTS: The mean [standard deviation (SD) ] age of enrolled patients was 66.7 (17.2)...

Sound, rhythm, rate, structure, function – countless features of the heart are measured to keep it healthy for as long as possible. Recently, an army of digital health technologies joined the forces of traditional preventive tools in cardiology to counter stroke, heart attack, heart failure or any other cardiovascular risks. In the future, minuscule sensors, digital twins, and artificial intelligence could strengthen their ranks. Let’s see what the future of cardiology might look like! Fitness trackers, chatbots and A.I. against heart disease Let’s say 36-year-old Maria living in Sao Paulo in 2033 d...

Objective : Atrial fibrillation (AF) is the most commonly experienced arrhythmia and it increases the risk of stroke and heart failure. The challenge in detecting the presence of AF is the occasional and asymptomatic manifestation of the condition. Long-term monitoring can increase the sensitivity of detecting intermittent AF episodes, however it is either cumbersome or invasive and costly with electrocardiography (ECG). Photoplethysmography (PPG) is an unobtrusive measuring modality enabling heart rate monitoring, and promising results have been presented in detecting AF. However, there is still limited knowledge ab...
