12/01/2022By combining information from two advanced imaging techniques with clinical data, physicians can improve their prediction of heart attacks, according to research published in the January issue of The Journal of Nuclear Medicine.
07/01/2022Using a high-resolution infrared camera, sports scientists from the Johannes Gutenberg University Mainz have discovered how blood flow in the human skin changes during exercise. They now want to exactly quantify these changes with machine vision and thus gain knowledge for performance diagnostics and beyond.
03/01/2022Patients waiting for a donor organ must have a lot of patience and a bit of luck. Aging and a rise in chronic disease prevalence means the need for donor organs is much greater than the number that is available. To help those who need organ transplants, scientists must create new technologies.
23/12/2021Pulmonary embolisms are dangerous, lung-clogging blot clots. In a pilot study, scientists at the Icahn School of Medicine at Mount Sinai showed for the first time that artificial intelligence (AI) algorithms can detect signs of these clots in electrocardiograms (EKGs), a finding which may one day help doctors with screening.
16/12/2021For cardiac arrest victims, minutes can mean the difference between life and death. It's vital that medical emergency response teams get to them quickly, but in more remote, rural areas this can sometimes be difficult. "HORYZN" is an initiative of students and has developed a remote-controlled, AI-supported rescue drone with a defibrillator on board for just such emergencies.
08/12/2021Using artificial intelligence, a team of University at Buffalo researchers has developed a novel system that models the progression of chronic diseases as patients age.
02/12/2021A drug-coated balloon catheter inserted in minimally invasive cardiac surgery is increasingly serving as a replacement for the risky stent treatment. In current practice, the balloons are often coated manually. A new device is intended to automate this time-consuming procedure. Along with partners, a team from the Fraunhofer IPK is developing a prototype of such a device.
19/11/2021Atrial fibrillation—an irregular and often rapid heart rate—is a common condition that often leads to the formation of clots in the heart that can travel to the brain to cause a stroke. A researchers team has developed an artificial intelligence–based method for identifying patients who are at risk for developing atrial fibrillation and could therefore benefit from preventative measures.
03/11/2021A defective heart valve is the second most common form of heart disease. Most cases involve a narrowed aortic valve, but often the mitral valve can also be affected. Prostheses significantly increase the life expectancy of those with the disease. While bioprosthetic heart valves have some advantages over mechanical ones, they can become calcified relatively quickly.
19/10/2021A special artificial intelligence (AI)-based computer algorithm created by Mount Sinai researchers was able to learn how to identify subtle changes in electrocardiograms (also known as ECGs or EKGs) to predict whether a patient was experiencing heart failure.
08/10/2021Risks during surgery, especially cardiological risks, are still very high in the Western world. However, conventional methods for measuring such risks before surgery are costly or even not always meaningful. And increasing economization in hospitals also makes it more difficult for staff to find time for a comprehensive pre-op analysis.
22/09/2021Social distancing, working from home, limited social activities: the COVID-19 pandemic has prompted many people to become more inactive, sedentary, and therefore more susceptible to ailments. Simple fitness programs and regular exercises can help counteract the negative effects of inertness. And paradoxical as it may sound, the pandemic also gives us the chance to get moving again.
02/08/2021Image-guided surgery is based on medical imaging. However, past imaging technologies performed while the patient is awake cannot deliver a complete view that facilitates a visual differentiation of structures such as blood vessels and nerve tracts. In a study, scientists developed a non-invasive imaging modality that enables multiplexing, deep tissue penetration, and real-time resolution.
02/08/2021Robots in the operating theatre are no longer a rarity in certain medical fields - they support and relieve doctors and sometimes they can make operations more efficient and easier with artificial intelligence (AI). However, they are rarely found in the operating theatre during cardiological interventions.
02/08/2021A high degree of precision is required for operations involving the cardiovascular system. This is based on medical imaging. In practice, however, these still face a number of challenges that can impair image quality. The further development of imaging techniques represents a forward-looking field of research in order to be able to improve surgical treatment.
02/08/2021Surgical intervention is often inevitable when blood vessels become narrowed, blocked, or damaged. Surgeons use stents and medical balloons to open and widen the arteries, suck out the obstructing clots and use a catheter to examine the vessels. Intraoperative cardiovascular imaging is an essential tool to guide the catheters and instruments during the minimally invasive procedures.
08/04/2021According to a study, a mobile rhythm patch can help detect and prevent strokes. In this interview with MEDICA, co-study leader Prof. Rolf Wachter explains how the mobile rhythm patch works and which insights the study results provide for the future.
15/12/2020Atrial fibrillation is an irregular heartbeat that can lead to blood clots and trigger strokes. To correct the condition, physicians use medication or surgical intervention by means of catheter ablation. This surgical method on the beating heart is a standard and safe procedure but there is always room for improvement.
09/03/2020Treatment 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.
03/02/2020According 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.
03/02/2020Chronic 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.
08/11/2019If 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.
04/11/2019Since 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.
23/09/2019For 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.
08/05/2019Atrial 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.
08/04/2019Cardiac 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.
08/08/2018Some 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.
23/07/2018Every 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.
17/05/2018Ventricular 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.
08/05/2018Multidrug-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.
22/03/2018Virtual reality and medicine are increasingly mentioned in the same context. In addition to the development of applications that support the treatment of patients suffering from chronic pain and anxiety, this technology also benefits medical staff. Two months ago, the Ulm University Hospital has opened the VR Lab, where medical students can train and learn with the help of 3D organs.
08/01/2018Few patients with heart failure are fortunate enough to receive a donor's heart. Ventricular assist devices (or heart pumps) have been around for several years and are designed to buy time as patients wait for a transplant. Unfortunately, the body doesn't always tolerate these devices.
