A large study has linked abnormal heart rhythm to cognitive decline, the latest evidence that connects common cardiovascular conditions with dementia. But there is some good news: Early diagnosis and medication may completely remove the increased risk.
-
Heart tissue normally can't regenerate after an injury. But now, scientists at Max Planck have shown in mice that reprogramming the energy metabolism of the heart allows it to regenerate after a heart attack, which could open new therapies.
-
In a major step towards creating new organs on demand to alleviate donor waitlists, Stanford scientists have now received a contract and funding for experiments to 3D print human hearts and implant them into live pigs.
-
A new study has found that during exercise, the vagus nerve, essential to the body’s ‘rest and digest’ response, has a more important role in heart function than we thought. The findings could help treat diseases like heart failure.
-
A 58-year-old man with terminal heart disease has become the second patient to receive a pig's heart, in a complicated, high-risk xenotransplant. The first recipient died last year from complications, two months after the landmark world-first surgery.
-
A high resting heart rate, considered anything above 100 beats per minute, has been linked to an elevated risk of serious cardiovascular conditions such as coronary artery disease and stroke. Knowing how genes impact this is vital for preventative care.
-
Researchers have found that red blood cells have an innate ability to trigger a pathway that protects the heart from injury during periods of low oxygen, such as during a heart attack. The discovery could lead to new drugs that activate this pathway.
-
The warning signs of a deadly out-of-hospital sudden cardiac arrest differ significantly between the sexes, a study has found. Researchers hope their research will improve survival rates and educate people about when to call emergency services.
-
While most people attempting to lose weight will know that there is an optimal ‘zone’ in which fat metabolizes best, based on heart rate and age. Researchers have now found that for many people this is actually an inaccurate formula to be using.
-
Microplastics are everywhere. Now, two new studies have further examined microplastics’ effect on our health, with one finding that they cause brain inflammation and the second finding them in the heart, a completely enclosed organ.
-
When you think exercise, holding your body still in a pose for a minute hardly springs to mind as a workout. But scientists have found that isometric moves such as wall sits and planks may be even better for your heart than both weights and cardio.
-
Using a deep-learning AI model, researchers have turned the humble chest X-ray into a more powerful tool for diagnosing heart problems. They say their novel approach could be used as a quick and accurate way of assessing heart function.
