May 16, 2018 Scientists have shown for the first time that the blueprint for the four chambers of the human heart exists in the humble zebrafish, a study in eLife reports. The discovery provides key insights into processes that go wrong in congenital heart defects and means that researchers now have a simple model for […]Continue Reading ...
May 18, 2018 Acute kidney injury is one of the most common and serious complications of hospitalized patients. Acute kidney injury (AKI), an abrupt or rapid decline in kidney function, is an increasingly prevalent and potentially serious condition that often arises due to medical conditions or treatments that may deprive the kidneys of a normal […]Continue Reading ...
May 18, 2018 A new algorithm developed by UCLA researchers more accurately predicts which people will survive heart failure, and for how long, whether or not they receive a heart transplant. The algorithm would allow doctors to make more personalized assessments of people who are awaiting heart transplants, which in turn could enable health care […]Continue Reading ...
May 14, 2018 The most common heart medications may get an assist from nitric oxide circulating in the body, according to a new study out of Case Western Reserve University School of Medicine. Researchers showed that nitric oxide may help commonly used heart drugs maximize their benefits while improving heart function. In turn, the study […]Continue Reading ...
May 14, 2018 Atrial fibrillation patients who are diagnosed with carotid artery disease face higher risks for developing dementia, according to new research from the Intermountain Medical Center Heart Institute in Salt Lake City. Blockages in the carotid artery, which gradually build up as people age, restrict blood flow to the brain. The new study […]Continue Reading ...
May 11, 2018 Patients with an abnormal heart rhythm that can leave them at a higher risk of suffering from stroke still need treatment even after their heart rhythm seems to have returned to normal, say researchers at the University of Birmingham. Atrial fibrillation is the most common heart rhythm disturbance, affecting around 1.6 million […]Continue Reading ...
May 10, 2018 Annual well woman exams by OB/GYNs provide a golden opportunity to evaluate a woman’s heart health, according to a new joint advisory from the American Heart Association and the American College of Obstetricians and Gynecologists (ACOG) which stresses the benefits of collaborative care between OB/GYN specialists and cardiologists. As heart disease and […]Continue Reading ...
May 10, 2018 A Vanderbilt-led research team has discovered genetic variations that increase the risk of heart attack even when patients are receiving a statin drug like Lipitor or Crestor to lower their blood cholesterol. The findings, published by the journal Circulation, helps explain why some patients experience a heart attack or the need for […]Continue Reading ...
The helicoidal orientation of fibres in a ventricle wall is shown in bright colours, based on diffusion magnetic resonance imaging of a rat’s heart tissue. Credit: Shape Analysis Group/McGill University The human heart can be viewed as both a mechanical and an electrical device – one that contracts and pumps billions of times over an […]Continue Reading ...
May 15, 2018 By analyzing reported physical activity levels over time in more than 11,000 American adults, Johns Hopkins Medicine researchers conclude that increasing physical activity to recommended levels over as few as six years in middle age is associated with a significantly decreased risk of heart failure, a condition that affects an estimated 5 […]Continue Reading ...
May 14, 2018 Studies have shown that a simple treatment called lipid emulsion therapy -; fatty acids administered intravenously -; can heal damage to the heart after a heart attack or cardiac arrest. But researchers haven’t understood exactly how the treatment works or whether there are more effective ways to repair the heart. Now, UCLA […]Continue Reading ...
May 11, 2018 Presented at Heart Rhythm 2018, first-of-its-kind study includes results from Apple Watch, Samsung Galaxy Gear and Fitbit Charge 2 A new study is the first to validate the accuracy of wrist-worn wearable devices in measuring induced paroxysmal supraventricular tachycardia (PSVT), or episodes of rapid heart rate. Three common wearable devices including the […]Continue Reading ...
May 9, 2018 New research published in The Journal of Physiology has indicated a potential new stem cell treatment following a heart attack, by encouraging the regeneration of heart muscle cells. The low retention and survival rate of stem cells implanted in the heart had previously proven a sticking point for stem cell therapy following […]Continue Reading ...
May 9, 2018 The most common and potentially lethal complication following a heart attack is the heart’s inability to do one of its most basic jobs: beat at a normal rate. Following myocardial infarction, heart muscle cells are replaced by fibroblasts and new blood vessels, which do not conduct electricity and leave the heart susceptible […]Continue Reading ...
May 9, 2018 Similar to how protein clumps build up in the brain in people with some neurodegenerative diseases such as Alzheimer’s and Parkinson’s diseases, protein clumps appear to accumulate in the diseased hearts of mice and people with heart failure, according to a team led by Johns Hopkins University researchers. In experiments described in […]Continue Reading ...
