08/06/2022We are nowadays already able to weave implants out of artificial fibers that can replace tissue or heal injuries. Different materials like polymers or nitinol are used to create flexible shapes. But the materials and their uses can still be improved.
06/06/2022Researchers have developed 3D printed artificial heart valves designed to allow a patient’s own cells to form new tissue. To form these scaffolds using melt electrowriting – an advanced additive manufacturing technique – the team has created a new fabrication platform that enables them to combine different precise, customized patterns and hence to fine-tune the scaffold’s mechanical properties.
02/06/2022A specific protein in blood vessel cells plays a major role in the development of vascular and cardiovascular diseases: The presence of too many "thromboxane A2 receptors" hinders the formation of new blood vessels. A research team led by the Martin Luther University Halle-Wittenberg (MLU) was able to describe the underlying process for the first time.
25/05/2022A voice analysis app used by heart failure patients at home recognises fluid in the lungs three weeks before an unplanned hospitalisation or escalation in outpatient drug treatment.
17/05/2022Hyperpolarized nuclear magnetic resonance enables major medical advances in molecular diagnostics, for example for cardiovascular diseases or cancer therapy. Within the framework of the EU collaborative project "MetaboliQs", seven partners developed a microscopy method which enables the analysis of metabolic processes at the single cell level by means of diamond-based hyperpolarization.
27/04/2022Using lipidomics, a modern analytical method, the team led by Dr. Fabian Eichelmann from DIfE and DZD identified those lipids that are statistically associated with cardiovascular disease and type 2 diabetes.
15/04/2022A new artificial intelligence-based approach can predict, significantly more accurately than a doctor, if and when a patient could die of cardiac arrest.
12/04/2022What happens below the cellular level when the heart contracts and relaxes has long been unexplored. Thanks to new ultra-high-resolution electron microscopy techniques, scientists can now watch the heart beating – almost at a molecular level.
06/04/2022For people with atrial fibrillation, one of our most common cardiac disorders, dementia risk is elevated. This is shown by a University of Gothenburg thesis based on research at population level.
01/03/2022Catheter ablation is a way to treat irregular heartbeats, or arrhythmias, like atrial fibrillation. Although catheters are classified as single-use or disposable devices, the complex instruments can be reused multiple times thanks to extensive reprocessing.
24/01/2022It is an exciting time for space exploration: Will there be more space stations, lunar outposts, or Mars missions in the future? No matter where they are in space, lack of gravity causes astronauts to lose muscle mass during their missions. Even the fittest among them lose heart muscle. An experiment on the International Space Station (ISS) plans to detect whether sensors show heart changes.
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.
02/08/2021Surgical 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.
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.
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.
02/06/2020After a stroke, a patient’s life depends on getting acute care at a hospital. Vital monitoring systems ensure safe and effective treatment. An innovative tomographic imaging system is designed to help prevent the patient’s risky journey to radiology and to enable bedside monitoring of cerebral blood flow.
02/06/2020Stroke can affect anyone – older as well as younger people. The minutes after the stroke determine whether disability or death is the result. Only if acute care, inpatient treatment and rehabilitation are carried out in a targeted and effective manner, the chances are greater that only minor damage remains or that impairments even recede.
02/06/2020If someone is having a stroke, you call an ambulance. But getting to the hospital can be time-consuming. To prevent long-term disabilities and death, patients need to be treated as quickly as possible. According to a recent study by the Charité – Universitätsmedizin Berlin, mobile stroke units play a key role in this setting.
22/04/2020Wearables offer practical solutions for the flexible measurement of data. The sensor from cosinuss° is worn directly in the ear and offers a precise monitoring of vital parameters.
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.
03/02/2020Coronary heart disease can come as a complete surprise and occur suddenly. Cardisiography was designed to lower the risk and make faster intervention possible. As a non-invasive heart screening test, cardisiography offers the possibility of early detection for heart diseases.
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.
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.
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.
01/07/2019Physical activity plays a big role in today's society. Whether you are an amateur or professional athlete – incorporating exercise into your life positively impacts your mental and physical health. Ideally, sport should be fun, pressure-free and not overburden you. But can you measure individual performance and align it with sports?
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.
23/04/2018A bypass is a complicated structure. It is either made of synthetic materials that can cause blood clots and infections or created by using the patient’s veins. However, the latter often does not yield adequate material. A newly developed bioreactor could solve this problem in the future. It is designed to tissue engineer vascular grafts by using the body’s own material.
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.
