24/08/2016According to new research, green tea could prevent a deadly condition in the body's main artery. A Kyoto University team has found that abdominal aortic aneurysm - a condition in which the main artery becomes overstretched and bloated - developed less frequently in rats that drank green tea polyphenol, a major component of green tea.
23/08/2016Combining ultrasound energy and microbubbles to poke holes in cells may prove to be a new tool in the fight against cardiovascular disease and cancer, according to researchers from the University of Pittsburgh and UPMC. A study on this gene therapy approach, called sonoporation, is published in the Proceedings of the National Academy of Sciences (PNAS).
08/08/2016Eliminating racial disparities in the outcomes of programs to control blood pressure can be accomplished with a few one-on-one coaching sessions delivered by health professionals - but not if the program requires people to get to a clinic, according to results of a new Johns Hopkins Medicine study.
02/08/2016Epilepsy is an extremely common disorder affecting people of all ages, from infants through teenagers to older adults. One of the most mysterious things about this disorder is that about 6 percent of the people with epilepsy have an unusually high incidence of sudden unexpected death.
18/07/2016A new technique developed by a UBC researcher could make tissue regeneration cheaper and safer for health-care systems and their patients.
15/07/2016Telemedicine could save hundreds of heart patients from a hospital stay each day. Studies show that digital, around-the-clock care can greatly improve life expectancy and quality of life. Experts see telecardiology as a promising early-warning system to improve the quality of care in heart patients – particularly in rural regions.
04/07/2016A clinical trial testing mobile videoconferencing as a means for physicians to diagnose stroke patients while they're being transported to the hospital has found that a tablet-based system produced diagnoses highly correlating with a bedside assessment -- a finding that could have important implications for the early treatment of stroke and for preventing the disability it causes.
29/06/2016A research team led by investigators at Beth Israel Deaconess Medical Center (BIDMC) and Seoul National University has developed a new electric mesh device that can be wrapped around the heart to deliver electrical impulses and thereby improve cardiac function in experimental models of heart failure, a major public health concern and leading cause of mortality and disability.
22/06/2016Exercise makes you healthy – oftentimes even when you are sick. That’s why doctors hardly ever recommend taking a break from it. Even patients who are about to receive a heart transplant can benefit from sports. As is so often the case, the dose makes the poison. We asked sports medicine physician Prof. Martin Halle, what people need to consider.
16/06/2016As men and women grow older, their chances for coronary heart disease also increase. Atherosclerosis is a condition in which plaque builds up inside the arteries, which can lead to serious problems, including heart attacks, strokes or even death.
15/06/2016Coronary or peripheral bypasses are the most frequently performed vascular operations. Although one million patients per year and around the world, undergo this intervention, its failure rate reaches 5 percent, because of poor vessel healing, leading to vessel graft occlusion.
08/06/2016Electronic anti-theft systems still post a threat to cardiac device patients, according to research by Professor Robert Stevenson, senior scientist at Greatbatch Medical in Santa Clarita, California, USA.
02/06/2016Growing tissues and organs in the lab for transplantation into patients could become easier after scientists discovered an effective way to produce three-dimensional networks of blood vessels, vital for tissue survival yet a current stumbling block in regenerative medicine.
27/05/2016Engineers at the University of California San Diego have developed the first flexible wearable device capable of monitoring both biochemical and electric signals in the human body.
02/05/2016Heart failure or cardiac insufficiency presents an extra strain on patients because it severally limits everyday performance and deprives them of energy. Due to their intense need for movement, children are particularly strongly affected. However, the disease is frequently not detected until the physical performance is already declining. An early diagnosis could prevent this.
01/05/2016In addition to patient counseling and clinical diagnostics, the lion’s share of a cardiologist’s work consists of collecting data to be able to better treat future cases based on the gathered information. Until now, this data was recorded in Excel spreadsheets or many other communication platforms. A software is designed to facilitate a cross-industry exchange.
01/03/2016Fortunately, only a handful of newborns are affected by them, though this determines if not the rest of their lives then, at least, the first few years of affected children: congenital heart defects. After the necessary surgeries, the small patients repeatedly need to return for checkups. Until now, these were conducted using MRI scans. 4D ultrasound can be an alternative.
09/02/2016Many people suffer from atherosclerosis, especially in developed countries. The buildup of fatty deposits inside the arterial blood vessels leads to strokes and heart attacks. Now, a new method is designed to get to the root of the problem, and with the help of nanoparticles inject new turbo replacement cells into the blood vessels which are intended to exert their curative effect.
01/02/2016Children, especially newborns, are generally no longer simply considered to be small adults whose treatment just needs to be "reduced". This is why a pediatrician’s education includes several specialties because ultimately everything in terms of care comes together here.
01/02/2016Self-healing powers like a superhero on the big screen? That’s the aim of regenerative medicine; at least in a very broad sense. This promising field of biomedicine is currently highly dynamic with innovative technologies and development. New methods are designed to help propel medicine into a whole new sphere.
08/01/2016There are various artificial heart valves available for children, but they have one essential drawback: they need to be replaced because the children are still growing. The artificial valve, on the other hand, remains the same size – and subsequently becomes too small. This is why an artificial heart valve that grows over time would be ideal.
01/09/2015Smartphone apps and wearable sensors have the potential to help people make healthier lifestyle choices. Self-monitoring therefore is one of the core strategies for changing cardiovascular health behaviors. On the other side, patients benefit from sharing their data with doctors and electronic health record (EHR) systems.
03/08/2015Nuclear medicine physicians use so-called gamma cameras for myocardial perfusion scintigraphy. The devices record radioactive substances that are injected into the patient and show changes in the heart muscle (myocardium). Now a new gamma camera is able to record images faster and by using much less radiation.
01/07/2015When measuring myocardial activity, it is important for the skin to always stay moist under the electrodes of the ECG. Only then can data be consistently transferred. Athletes have an easier time with this: they are used to sweating. This is a lot harder for older patients.
01/07/2015In the case of cardiac arrhythmia, the normal heart rate gets out of balance due to various reasons. In some cases, it is necessary to implant a cardiac pacemaker. Just like with any intervention, this type of surgery also involves risks. In the worst-case scenario, this can lead to abnormal wound healing or obliteration of the vascular system.
01/07/2015Deep vein thrombosis is not just a risk factor for frequent flyers but also for wearers of cardiovascular implants and newly operated patients. Blood thinners prevent these dangerous blood clots from forming, but they need to be carefully adjusted and do not work the same way in every patient. A detailed analysis of platelets (thrombocytes) could prevent complications in the future.
22/05/2015Braided stents are nothing new in medicine, but their manufacturing process is still time-consuming. This is why Professor Stefan Jockenhövel from the RWTH Aachen University and his team want to make machine production possible.
23/02/2015An 80-year-old female patient needs a new aortic valve replacement. Since the old one is severally calcified, the leaflets no longer open properly. Due to various factors, the patient is considered inoperable. Nevertheless, to make surgery possible for her, specialists at the Heart and Diabetes Center NRW in Germany have prepared the intervention based on an exact 3D heart replica.
08/08/2014A magnesium implant will soon be available to help patients, who exhibit damage in the high-pressure area of the heart. The implant protects a tissue matrix where new cells that replace the affected tissue are meant to grow. The implant itself is supposed to completely dissolve after several months. MEDICA.de spoke with D. Eng. Thomas Hassel about this exciting project.
02/06/2014Sudden deaths of football players make headlines time after time: competitive athletes who are the idols of many people die just when they are on the playing field and in the limelight. Congenital heart defects often cause their death. Sports physicians and FIFA now plan to ascertain data that can help improve preventive examinations in competitive football.
02/06/2014"Sports are good for your health", as the saying goes. Regular exercise promotes the health of our blood vessels and prevents vascular diseases. However, many years of competitive sports can also have negative effects on vascular health and increase the risk of myocardial infarction. Prof. Martin Halle of the Technical University Munich explains at MEDICA.de what athletes need to pay attention to.
08/01/2014Heart diseases can be triggered by special viruses that affect the cardiac muscle. Preventive drugs could definitely be developed – if the virus does not mutate.
