Atherosclerosis is a chronic disease involving the build-up of plaque consisting of fat, cholesterol, calcium, and other blood-based substances. Sequentially, the plaque hardens and narrows the arteries to limit the … Continue Reading Molecules alter the gut microbiota to reverse narrowing of arteries in an animal study.
More than one million artificial pacemakers are implanted in patients across the globe annually due to abnormal heart rhythms. The devices are placed in the chest or abdomen, using electrical … Continue Reading Biological pacemakers produced from human fat cells.
An all too familiar and frustrating sight for doctors and nurses the world over, patients who suffer a cardiac arrest under their care due to trauma involving car accidents, gunshot … Continue Reading First human placed in suspended animation.
There are a staggering estimated 785,000 new heart attack cases in the United States each year, with no gold standard treatment for repairing the resulting damage to cardiac tissue. There … Continue Reading A First-in-human trial shows hydrogel to repair heart is safe to inject.
Thrombosis occurs when blood clots disrupt the normal flow of blood in the body, which can cause severe health problems such as pulmonary embolism, heart attack or stroke. Current treatments … Continue Reading Smart patch successfully monitors blood to release blood thinners as needed in animal model.
During a heart attack, clots or narrowed arteries block blood flow, harming or killing cells within the tissue. However, the damage doesn’t end after the crushing pain subsides. The heart’s … Continue Reading Injectable gel used to prevent heart failure in animal model after heart attack.
Heart failure is one of the main health problems worldwide, and the urgent medical needs relating to it have positioned cardiovascular research as one of the most actively evolving fields … Continue Reading Study links adult heart regeneration to telomere length in animal model.
Researchers have long known that the buildup of plaque in arteries can cause them to narrow and harden, potentially leading to a whole host of health problems, including heart attack, … Continue Reading Researchers identify new contributor to heart disease, new scope of treatment.
Dramatic health consequences of air pollution were first described in Belgium in 1930 after the Meuse Valley fog. The World Health Organization (WHO) considers air pollution as one of the … Continue Reading Air pollution linked to increased heart attack risk even at ‘safe’ levels.
A blood clot is a dangerous health situation with the potential to trigger heart attacks, strokes and other medical emergencies. To treat a blood clot, doctors need to find its … Continue Reading New contrast allows whole-body blood clot scans in animal model.
A new non-invasive scan can be used to determine the extent of plaque buildup in the heart accurately predicts the likelihood of heart attack or death over a 15-year period. … Continue Reading New non-invasive test predicts long-term death risk in humans even without heart disease symptoms.
In a life-threatening situation, the heart beats faster and harder, invigorated by the fight-or-flight response, which instantaneously prepares a person to react or run. Now, a new study by researchers … Continue Reading Researchers map how calcium uptake in mitochondria during a heart attack causes large cell death.
A research team showed that a nanotherapeutic medicine can halt the growth of artery plaque cells resulting in the fast reduction of the inflammation that may cause a heart attack, … Continue Reading Nanotechnology successfully used to halt atherosclerotic plaque growth in animal model.
Adding two non-invasive imaging tests to traditional cardiovascular disease risk factor assessment more precisely predicts a healthy patient’s future risk of heart attack, stroke, or premature death, according to a … Continue Reading New non-invasive bioimaging can detect coronary artery disease long before it strikes.
The heart tissue of mammals has limited capacity to regenerate after an injury such as a heart attack, in part due to the inability to reactivate a cardiac muscle cell … Continue Reading Researchers induce microRNA-based cardiomyocyte proliferation after heart attack in animal model.
Researchers from the UC San Diego and the University of Iowa have identified a key piece in the complex molecular puzzle underlying heart failure, a serious and sometimes life-threatening disorder affecting more … Continue Reading Researchers identify protein responsible for epigenetic change in heart failure.
