Heart

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.

We could soon be checking our heart rhythm while grocery shopping, thanks to a device incorporated into the handle of a supermarket cart designed to monitor for atrial fibrillation, a common heart arrhythmia that’s a key risk factor for stroke.

Researchers have transplanted precursor stem cells into the damaged heart muscle of pigs, repairing injured cells and improving heart function. The study may lead to a treatment that can regenerate heart muscle damaged by a lack of oxygen.

For many, Monday means the weekend's over and it's back to work. Now, there's something else to worry about. Research has found that the most life-threatening type of heart attack is more likely to occur on a Monday than any other day of the week.

Engineers have developed a fully integrated wearable ultrasound device that monitors deep tissues in real-time for up to 12 hours. What's more, it's wireless, meaning that patients can stay mobile while doctors track their vital signs remotely.

Surgeons have successfully performed a first-of-its-kind procedure in utero to treat a potentially fatal genetic defect in the brain. Usually treated after birth, the new procedure could give newborns a better chance of a normal life.
