Scientists were surprised to discover that the four genes in the Id family play a crucial role in heart development, telling undifferentiated stem cells to form heart tubes and eventually muscle.
Scientists have demonstrated that the response of the human heart to an infarction is very different to what was previously thought.
New research has discovered a potential means to trigger damaged heart cells to self-heal. The discovery could lead to groundbreaking forms of treatment for heart diseases. For the first time, researchers have identified a long non-coding ribonucleic acid (ncRNA) that regulates genes controlling the ability of heart cells to undergo repair or regeneration. This novel RNA, called 'Singheart,' may be targeted for treating heart failure in the future.
New research helps to elucidate part of the mechanism whereby aerobic exercise protects the sick heart. The benefits of exercise range from prevention of cachexia -- severe loss of weight and muscle mass -- and control of arterial blood pressure to improved cardiac function, postponing a degenerative process that causes progressive heart cell death. About 70% of heart failure patients die from the condition within five years.
Patients at risk of heart attacks and strokes may be spotted earlier thanks to a diagnosis tool that uses near-infrared light to identify high-risk arterial plaques.
Women who experience hypertension during pregnancy face an increased risk of heart disease and hypertension later in life, according to a new study.
A new study on 240 emergency room patients shows just how much of a role a person's cholesterol plays, when in a crystallized state, during a heart attack.
A new study suggests long-term mortality trends may be better understood by focusing on life-years lost -- remaining life expectancy for a decedent -- instead of solely looking at cause of death.
A new study finds slightly more than half of heart patients are admitted to the CICU for noncardiac conditions, such as sepsis or renal failure, rather than for a heart condition.
A recent article finds that current smoking in older people increases the risk of developing frailty, though former smokers did not appear to be at higher risk.
Physicians identified a majority of patients with advanced heart failure as at high risk for transplant, left ventricular assist device (LVAD) or death while few of those patients considered themselves to be at high risk, according to a study.
A protein that enables fish to change the size of their hearts based on the temperature of the water has now been identified by researchers. Understanding how fish are able to naturally add and remove collagen could lead to the development of treatment modalities for humans that enables a more controlled way for the heart to repair itself after a heart attack.
Carrying extra weight could raise your risk of heart attack by more than a quarter, even if you are otherwise healthy.
Gata4 alone is able to reduce post-heart attack fibrosis and improve cardiac function in a rat model of heart attack. In rat fibroblasts in the lab, the molecular mechanism involves reduced expression of Snail, the master gene of fibrosis.
Biomedical engineers have grown miniature human blood vessels using stem cells taken from patients with an extremely rare genetic disease called progeria that causes symptoms resembling accelerated aging in children. The blood vessels exhibit many of the symptoms and drug reactions associated with progeria and will help doctors and researchers screen potential therapeutics for the disease, and other rare diseases, more rapidly.
Researchers report encouraging preclinical results as they pursue elusive therapies that can repair scarred and poorly functioning heart tissues after cardiac injury. Scientists inhibited a protein that helps regulate the heart's response to adrenaline, alleviating the disease processes in mouse models and human cardiac cells.
Researchers have compiled peer-reviewed evidence and crafted a guideline designed to help physicians and medical centers stop the use of a widely ordered blood test that adds no value in evaluating patients with suspected heart attack.
A team of researchers is mending broken hearts with an expanding tissue bandage a little smaller than a postage stamp.
Cardiac stem cell infusions could someday help reverse the aging process in the human heart, making older ones behave younger, according to a new study.
Automatic blood pressure devices are often used to assess blood pressure levels at home and in the clinic. But these devices are prone to significant errors, sometimes leading to the prescription of blood pressure-lowering medications to patients who don’t actually need them. Researchers have now developed a method to more accurately measure systolic blood pressure.
