Researchers grew a mini human heart to study fetal heart development

[ad_1] They’re now using the method to model and study congenital heart disease. While they’re still perfecting the process, the researchers believe these human heart organoids could be used to study other cardiovascular conditions, like chemotherapy-induced cardiotoxicity and the effects of diabetes on the developing fetal heart. “These minihearts constitute incredibly powerful models in which […]

3D map of a heart’s ‘brain’

[ad_1] Achanta et al. – iScience To help tackle those issues, the team mapped the locations of those neurons in a rat’s heart in vivid 3D detail. “In effect what we have created is the first comprehensive roadmap of the heart’s nervous system that can be referenced by other researchers for a range of questions […]

Lab-grown heart muscles transplanted into a human for the first time

[ad_1] These cells were then placed on small, degradable sheets, which were used to cover the damaged areas of the patient’s heart. The patient who received the transplant suffers from ischemic cardiomyopathy, where the heart has difficulty pumping because its muscles don’t receive enough blood. In some cases, this condition requires a heart transplant, but […]

FDA clears algorithms that detect heart murmurs and AFib

[ad_1] According to the company, the AI can identify heart murmurs with 87 percent sensitivity and 87 percent specificity. In comparison, primary care physicians unaided by AI had a 43 percent sensitivity and 69 percent specificity, according to a study in European Heart Journal. When used with the Eko DUO stethoscope, the AI reportedly detected […]

The FDA is fast-tracking an algorithm that screens for heart failure

[ad_1] The algorithm was introduced in a study published in Nature Medicine in January 2019. It was trained on 44,959 patients and tested on 52,870 patients. In those initial tests, it showed 87.5 percent accuracy. The algorithm is designed to work with Eko’s DUO digital stethoscope. The handheld device can be placed on the left […]

Heart Analzyer’s new Apple Watch app puts detailed data on your wrist

[ad_1] There are improvements for the iPhone as well, including half-month heart reports, support for breaks in your workout data and a screenshot mode for day graphs in case you want to share them with others. Heart Analyzer is free to download, although there are in-app purchases ($2 each) to unlock extended data, deeper analytics […]

Human patient put in suspended animation for the first time

[ad_1] The technique is officially called “emergency preservation and resuscitation” (EPR) and is being tested at the University of Maryland Medical Center on patients that arrive with acute trauma, such as a stab wound or gunshot. Given the nature of their injuries, these patients would normally have a survival rate of less than five percent. […]

AI can gauge the risk of dying from heart conditions

[ad_1] The approach is based on the notion that greater variability between heartbeats reflects greater risk. Scientists trained the machine learning system using historical data for patient outcomes. If a patient survived, their heartbeats were deemed relatively normal; if a patient died, their heart activity was considered risky. The ultimate risk score comes by averaging […]

FDA clears first personal ECG device to detect three heart arrhythmias

[ad_1] AliveCor emphasizes that this will only help “inform” chats with your doctor, not replace them. This still isn’t as sophisticated as a multi-lead ECG you’d receive at a clinic or hospital. However, it could be useful even if you’re in fine health. It should reduce the number of inconclusive ECG results you see, and […]

Stanford study finds Apple Watch can detect irregular heart rhythms

[ad_1] Just 34 percent of those who received notifications and agreed to wear an ECG patch for a week showed irregularities, but that was expected when atrial fibrillation is intermittent. About 57 percent of those who saw warnings went to a doctor, Stanford added. Notably, the study only included Apple Watches from Series 3 and […]
