Cardiovascular diseases: using AI to navigate the catheter

09.03.2020

Treatment of a heart attack or stroke caused by vascular occlusion must be prompt to prevent further damage to vital tissue. Unfortunately, the actual treatment is often preceded by a lengthy catheter-based procedure where the cardiologist manually guides the catheter to the affected vessel. AI might perform this task in the future.

AI helps predict heart attacks and stroke

27.02.2020

Artificial intelligence has been used for the first time to instantly and accurately measure blood flow, in a study led by UCL and Barts Health NHS Trust. The results were found to be able to predict chances of death, heart attack and stroke, and can be used by doctors to help recommend treatments which could improve a patient's blood flow.

TAVR shows similar safety outcomes as open-heart surgery

07.02.2020

A new study from the Smidt Heart Institute at Cedars-Sinai and other centers nationwide shows that patients who underwent a minimally invasive transcatheter aortic-valve replacement (TAVR), had similar key 5-year clinical outcomes of death and stroke as patients who had traditional open-heart surgery to replace the valve.

Cardiology: digital solutions support those coping with chronic illness

03.02.2020

According to the World Health Organization (WHO), cardiovascular diseases are the leading cause of death worldwide, taking an estimated 17.9 million lives each year. Acute events such as heart attacks and strokes stand out in this setting. Chronic heart diseases can also be a debilitating condition for many patients. If cardiology uses digital methods and tools, it can reach more affected people.

Digital cardiology: analyzing data beat by beat

03.02.2020

Chronic cardiovascular diseases are a growing burden worldwide. Most of them are diseases of civilization that spread, where lifestyle is improving or where it is good already. But the healthcare systems are not growing equally to keep up with this development. We can make up for this by making cardiological care smarter with eHealth and mHealth.

New stretchable battery can power wearable electronics

28.01.2020

Electronics are showing up everywhere: on our laps, in pockets and purses and, increasingly, snuggled up against our skin or sewed into our clothing. But the adoption of wearable electronics has so far been limited by their need to derive power from bulky, rigid batteries that reduce comfort and may present safety hazards due to chemical leakage or combustion.

IT: technique reveals whether models of patient risk are accurate

27.01.2020

After an affected person has a coronary heart assault or stroke, docs usually use danger fashions to assist information their therapy. These fashions can calculate a affected person’s danger of dying primarily based on elements such because the affected person’s age, signs, and different traits.

Electron cryomicroscopy shows cardiac thin filament structure

13.01.2020

Researchers at Osaka University used electron cryomicroscopy (CryoEM) to image essential cardiac muscle components, known as thin filaments, with unprecedented resolution. They also discovered the mechanism by which these filaments regulate heartbeat via cardiac muscle contractions in the presence or absence of calcium ions by changing their conformations.

Wearable AC monitors vital data

07.01.2020

One day, soldiers could cool down on the military battlefield – preventing heat stroke or exhaustion – by using "wearable air conditioning," an on-skin device designed by engineers at the University of Missouri. The device includes numerous human health care applications such as the ability to monitor blood pressure, electrical activity of the heart and the level of skin hydration.

Cardiac diagnostics – prompt and personalized

08.11.2019

If physicians suspect an acute myocardial infarction, they first order an ECG. This test is very established and allows cardiologists to quickly diagnose acute heart attacks – though the test does not detect less common heart attack symptoms. So far, those patients had to wait up to twelve hours before a heart attack could be accurately diagnosed or ruled out. But things are about the change.

MEDICA TECH FORUM: light-based imaging technique OCT

04.11.2019

Since its inception, MEDICA TECH FORUM has focused on the implementation of innovations and new technologies into clinical practice. 2019 marks the tenth year of the Forum. In honor of its anniversary, we will brighten things up a bit, as one of the focal points will highlight how optical coherence tomography (OCT) uses light to produce images.

Cardiac Tissue Engineering: a heart out of the Petri dish

23.09.2019

For patients waiting for donor organs, every day can mean the difference between life and death. Making things even more complicated is the fact that not every organ is a compatible match with the patient. It would mean enormous progress if we could grow organs from the patient's own cells in the lab. That's why patients with heart disease place big hope in tissue engineering.

mHealth: Atrial fibrillation detection – App supports heart health

08.05.2019

Atrial fibrillation is the most common type of persistent cardiac arrhythmia (irregular heart rhythm). Researchers estimate that 1.8 million Germans are presently affected by this disease. The condition is difficult to diagnose, frequently goes undetected and may result in a stroke. A new smartwatch medical app is designed to help patients detect atrial fibrillation before it’s too late.

Cardiac arrhythmia: treatment in the linear accelerator

08.04.2019

Cardiac arrhythmia is a group of conditions where nerve cells trigger uncontrolled contractions of the heart muscle. They are treated with either medicine or catheter ablation of the tissue. In an interdisciplinary collaboration, cardiologists and radiotherapists took a different approach and used high-precision radiation therapy to treat a patient for whom the other options proved unfeasible.

WAKE-UP study a wake-up call for acute stroke care

08.08.2018

Some solutions are simple, though not necessarily obvious. The WAKE-UP study, which included 70 participating European stroke centers, has now studied a relatively simple procedure to manage the acute care of stroke patients and avoid potential long-term effects. Best of all, it is available wherever MRI is offered.

Regenerative heart valves: from simulation to replacement

23.07.2018

Every year, more than 250,000 patients worldwide receive heart valve implants. Children require repeated replacement surgery because their bodies are still growing, the prosthetic heart valves are not. Regenerative heart valves solve this problem. Until now, we have only been able to monitor how these living implants develop in the body after the fact. Computer models now make this predictable.

Resuscitation via videostream – how EmergencyEye can save lives

02.07.2018

When the heart stops beating, irreversible brain damage occurs within minutes without resuscitation. Meanwhile, action is only taken in very few instances of cardiac arrest. Even first responders frequently feel helpless in this situation. In Germany, approximately 65,000 people die each year from sudden cardiac arrest. This is where EmergencyEye comes in to offer valuable support.

Ventricular fibrillation – Using ultrasound to detect its causes

17.05.2018

Ventricular fibrillation is a life-threatening condition that occurs when the heart muscle exhibits a rapid, erratic beat. The cause might be a circulatory system disease or heart attack. Researchers in Göttingen are now developing an ultrasound technique to get to the bottom of ventricular fibrillation and cardiac arrhythmias and facilitate better treatment options.

Organ Care System: treatment under extreme conditions

08.05.2018

Multidrug-resistant organisms that are treated with a dosage that exceeds the regular dose a hundred times and at temperatures of over 40 degrees Celsius – the human organism is unable to handle it. Yet if the diseased organ is treated outside of the body, extreme conditions are an option. For the first time, physicians have succeeded in treating a severe case of pneumonia by using the OCS.
