For the examination of coronary blood vessels, intravascular methods with imaging technologies are already state-of-the-art. However, ultrasonic methods, which are used to gather information about the tissue, can only be used externally, up to now. The piezo electronical components necessary for this have not been sufficiently miniaturized to be inserted into the blood vessels.
On top of the meaning and mystery that humans heap on the heart, it is first and foremost, a muscle. And one that beats about once a second for a person’s entire life, with no rest. Given its vital importance, it’s ironic researchers have only recently made direct observations of its subcellular parts in motion.
Despite messages to the contrary, most women being seen by a doctor for the first time with suspected heart disease actually experience the same classic symptoms as men, notably chest pain and shortness of breath, according to a study led by the Duke Clinical Research Institute.
Liposomes are currently used as drug delivery vehicles but recognized by the immune system. Scientists from the universities of Basel and Fribourg have shown that special artificial liposomes do not elicit any reaction in human and porcine sera as well as pigs. The study was published in the Journal Nanomedicine: Nanotechnology, Biology, and Medicine.
CT angiography (CTA) is evolving from a morphological – anatomical – to a functional imaging modality. In the past two years, cardiac CT perfusion measurement techniques were launched that predict which lesion will cause a reduction in blood flow.
The CSI Congress (Congenital, Structural and Valvular Interventions) is one of the major fixtures for catheter therapy of congenital and structural heart defects. Key moments in this high profile event are live broadcasts and the audience can not only to listen to but also interact with the teams in the cath labs involved.
Following a heart attack or other heart trauma, the heart is unable to replace its dead cells. Patients are often left with little option other than heart transplants, which are rarely available, or more recently cell therapies that transplant heart cells into the patient's heart.
Leading cardiologist Valentin Fuster, MD, PhD, has developed a free mobile application called “Circle of Health” to empower individuals around the globe to take action to comprehensively assess and enhance their daily overall heart health. Cardiovascular diseases are the number one cause of mortality in the world. Dr. Fuster has created “Circle of Health” for the daily promotion of…
Individuals with depression are more than twice as likely to have hospitalizations that might be preventable with timely outpatient medical care in the community, a new study finds.
A common heart drug may stop the progression of angiosarcoma, a cancer of the inner lining of blood vessels, according to a study by researchers at Texas Tech University Health Sciences Center (TTUHSC) El Paso.
A discovery about how the body deals with the cholesterol contained within its dying cells has suggested an exciting new approach to control people’s cholesterol levels – and thus their risk of developing heart disease.
Every year, worldwide, over a million patients have a pacemaker or defibrillator implanted. Home monitoring systems can significantly improve the safety and quality of life for these patients, says Professor Gerhard Hindricks, head physician in the rhythmology department at Leipzig’s Heart Centre. Report: Sascha Keutel
A new 3D computer modeling system may significantly improve a surgeon's ability to select the best sized donor heart for children receiving heart transplants, according to research presented at the American Heart Association's Scientific Sessions 2015.
Researchers have shown that people with high blood pressure develop changes in their hearts even before symptoms appear. These changes are known to put people at risk of dying early, and the new work suggests it is possible for doctors to recognise such signs of heart disease earlier than they can today - by examining detailed images of the heart.
Eating more fruits and vegetables as a young adult may keep your arteries free of heart disease 20 years later, according to research in the American Heart Association journal Circulation.
Cardiac catheterisation is the gold standard for diagnosing coronary artery disease (CAD), the main cause of death worldwide. More than 3.5 million invasive coronary angiographies (ICAs) are performed in the European Union each year, tendency rising. Nearly 60 percent of these minimal invasive examinations do not result in further treatment, since the patients do not have obstructive epicardial…
Scientists have evidence that Popeye was right: Spinach makes you stronger. But it’s the high nitrate content in the leafy greens — not the iron — that creates the effect.
With the world’s elderly population expected to double by 2050, understanding how aging affects the body is an important focus for researchers globally. Cardiovascular disease, the No. 1 cause of death worldwide, often is associated with aging arteries that restrict blood flow. Now, University of Missouri researchers have identified an age-related cause of arterial dysfunction, a finding that…
It is estimated that half of all cancer patients suffer from a muscle wasting syndrome called cachexia. Cancer cachexia impairs quality of life and response to therapy, which increases morbidity and mortality of cancer patients. Currently, there is no approved treatment for muscle wasting but a new study from the Research Institute of the McGill University Health Centre (RI-MUHC) and University…
Coronary artery disease (CAD) is the major killer worldwide. Its early detection can save the lives of many. Computed tomography (CT) has shown tremendous results in this area, but its advantage over more invasive techniques remains to be demonstrated, especially in patients with low to moderate risk.
As new cardiac genetic testing panels become available, cardiologists have been warned not to lose sight of the importance of comprehensive clinical evaluation. While genetic testing is helping to identify more people at risk of inherited conditions, experts stress they are only part of the diagnostic toolkit.
They did it for heart attacks. Can cardiologists now lead an effort to speed up the emergency medical response for stroke? Over the past five years, the Stent for Life initiative organised by interventional cardiologists has pushed majors medical centres to assure 24/7 coverage and reduce the time to treatment for patients showing up with severe chest pain.
The challenges and advantages of using echocardiography as an invaluable tool in the assessment of Hypertrophic Cardiomyopathy have been highlighted at a major UK cardiology conference.
The conventional 12-lead ECG has certainly proved its worth in displaying rhythm disorders or ischemia. Nevertheless, as the display possibilities of a 12-lead ECG are limited to only about 110 degrees of the heart, an exact location of a cardiac event often cannot be determined.
The role transthoracic echocardiography plays in a number of common clinical scenarios was discussed by leading cardiac imaging experts at this year’s British Cardiovascular Society Conference.
