22.07.2022Chest pain, shortness of breath, a brief loss of consciousness – warning signs that suggest a heart attack. But it might also be Takotsubo syndrome, also known as stress cardiomyopathy or broken heart syndrome with symptoms that resemble a heart attack. Yet it is of utmost importance to differentiate between the two conditions to initiate the right treatment.
01.03.2022Atrial Fibrillation is the most common type of persistent heart arrhythmia, affecting around half a million Germans alone. People with atrial fibrillation have a greater risk for ischemic stroke, making early and effective treatment critical to prevent serious complications. Unfortunately, many patients don’t even know they have atrial Fibrillation.
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.
03.02.2022The University Hospital Düsseldorf is researching a new method of heart imaging in the MRI: It can detect the early formation of coronary heart disease and show associated lesions before they cause any symptoms. A contrast agent containing fluorine atoms is used for this. We learn more about this method in the video interview with Prof. Ulrich Flögel and Dr. Florian Bönner.
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.
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.
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.
31.08.2021Determining an individual’s blood group based on genetic tests instead of merely traditional blood tests can provide a better picture of the risk of cardiovascular diseases.
30.08.2021Screening for atrial fibrillation in 75- and 76-year-olds could reduce the risk of stroke, severe bleeding and death, according to a study at Karolinska Institutet in Sweden that has been published.
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.
02.08.2021Image-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.
02.08.2021A 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.
02.08.2021Robots 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.
23.07.2021Engineers at the University of California San Diego developed a soft and stretchy ultrasound patch that can be worn on the skin to monitor blood flow through major arteries and veins deep inside a person's body.

07.04.2021Tempus, a leader in artificial intelligence and precision medicine, announces that the U.S. Food & Drug Administration (FDA) has granted the company Breakthrough Device Designation for its ECG Analysis Platform.
15.03.2021Heart surgery is difficult even for experienced surgeons and therapeutical success is not always certain. Physicians need to rely on their experience when choosing and planning the correct intervention. A computer model could help them in the future: The digital twin heart could be fed with patient data and then simulate whether an intervention will be successful.
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.
20.11.2020Bringing the technology to the patient and not the other way around – that is the idea behind CardioSecur. The physician can connect the mobile ECG system to his smartphone and thus have it with him always and everywhere. We asked MD and Founder Felix Brand how this works, to what extent patients also benefit from it and why the technology is particularly useful in corona times.
19.03.2020Regenerative medicine often relies on implants and materials that support healing in our body. Collagen has a special significance here. It is compatible to the body and offers an excellent environment for the growing of new cells. In our video, we took a look on where collagen and collagen products for medicine come from.
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.
23.04.2019According to WHO, about 251 million people worldwide had Chronic Obstructive Pumonary Disease in 2016. COPD denotes not a single, but several diseases that are caused by smoking and air pollution, among others. Patients at a later disease stage often need ventilation and are thus bound to the location of their devices.
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.
