A new injectable, temporary pacemaker could help correct a heart arrhythmia in an emergency. This nanoparticle gel can regulate the heart’s electrical signals for up to five days before dissolving harmlessly in the body.

Smoking, obesity, and stress. They're all common causes of damaging cardiac events. However, a just-published study says a new culprit should be added to the list of the risks that can hurt our hearts: constipation.

While there has been a general consensus that olive oil and other plant-based fats are better for you than butter, scientists have now put it beyond doubt, combining diet-intervention and previous cohort research to assess serious disease risk.

An existing drug has significantly improved the symptoms of obstructive sleep apnea – so much so that many trial participants stopped using CPAP machines. It stands to be the first therapeutic to effectively treat the condition, which affects millions.

Even brief periods of anger caused by triggering memories can negatively impact our blood vessels' ability to relax. That's the finding of a new study that could have implications on how we look at heart attack and stroke risk.

A study has found that tai chi was more effective than aerobic exercise at lowering blood pressure in 18-to-65-year-olds with prehypertension, a condition that can progress to high blood pressure and other cardiovascular diseases.

Research has linked the death of a sibling early in life to a 17% increased risk of cardiovascular disease, with most being early-onset. The findings highlight the need to provide support to bereaved siblings to reduce the risk of future health issues.

Researchers have identified an efficient and cost-effective two-step screening strategy that, compared to the current one-step approach, more accurately identifies which type 2 diabetics need treatment to prevent life-threatening heart failure.

New research shows that waiting too long in the day to have your first or last meal could have a negative impact on cardiovascular health. The study, which used data from 103,389 people, says that every hour counts when it comes to your mealtimes.

Scientists have discovered a new mechanism for how type 2 diabetes takes hold, and demonstrated in mice that blocking a particular enzyme could open a new avenue of treatment for the disease.

Far beyond concerns about waistlines, reaching for fatty foods during stressful times can have a dangerous impact on cardiovascular function and then significantly impair our body’s ability to return to normal after the tough time subsides.

Eating less meat is known to be good for heart health, but studies have been hampered by confounding factors such as genetics and background. Now, 22 sets of twins on 'healthy' meat and plant-based diets provide us with the best comparative data yet.
