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.
-
For all they do for us, our hearts aren't very good at repairing themselves. Now however, inspired by young hearts, researchers have transmuted scars into healthy tissue in mice, walking back the damage brought about by heart attacks.
-
Quick, accurate detection of a blocked artery is critical following a cardiac arrest admission to hospital. Doctors are hoping a new wrist device, currently undergoing human trial, will save both them and their patients precious time in an emergency.
-
Atrial fibrillation affects millions of people worldwide. Researchers have now developed a new procedure that shows great promise as a safe, quick and effective alternative to existing surgical methods used to treat the condition.
-
Researchers have demonstrated a new technique for helping heart cells regenerate after a heart attack, using mRNA to return the cells to a stem-cell-like state. Tests in mice showed drastic improvements to heart function a month after a heart attack.
-
Researchers in the US have found changes to electrical activity in the heart can help predict which hospitalized COVID-19 patients are more likely to decline and die. The biomarker is easily measurable and may predict death several days in advance.
-
Scientists have made an intriguing discovery that could see radiation therapy become a less invasive treatment for heart arrhythmia. The technique seems to activate the heart cells to revert to a younger state and repair the tissue.
-
Researchers have deployed drones carrying defibrillators to the sites of real-world cardiac arrests for the first time. On average, the unmanned aircraft arrived well ahead of ambulance crews, with the medical devices safely in tow.
-
Heart cells don’t naturally replenish, so after a heart attack it stays permanently damaged. Cambridge researchers have now stumbled onto genes that appear to trigger heart cell regeneration – and they did so by accident, while researching cancer.
-
People living in the hottest places on Earth may be up to three times as likely to die from a heart-related cause, according to a newly published study. Heat-related stress could be made worse in the coming decades by the effects of global warming.
-
The heart is notoriously fragile, having quite a lot of difficulty in repairing itself after sustaining damage. But now, researchers from the University of Calgary have found a previously unidentified cell population in the fluid that surrounds the heart, which seems to help heal injuries.

According to some folks, smart speakers such as Google Home and Amazon Echo simply make us lazy while needlessly adding electronic complexity to our lives. Thanks to new research, however, the things may someday prevent people from dying of cardiac arrest while sleeping.
