Cardiac

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.

The main risk factors for heart disease are lifestyle choices like a bad diet, smoking, lack of exercise – and poor sleep. That last point has gone relatively unstudied, but new research out of Harvard has found the chemical chain reaction that links disrupted sleep and cardiovascular disease.

​A new study suggests the damage caused to a person’s heart from years of sedentary behavior can be successfully reversed by the right “dose” of exercise. The study found that exercising four to five times per week can improve heart elasticity as long as the training begins before the age of 65

Great news! According to the results of a new study, sexual activity is very unlikely to result in a sudden cardiac arrest, especially if you are a woman. On the flip side, if you are unlucky enough to experience a not-so-happy ending, your chances of survival are pretty poor.

​When someone has a cardiac arrest, their chance of survival decreases by 10 percent for every minute that passes before they receive treatment. That's why an app has been created, that finds civilians who are trained in CPR and gets them to the location of cardiac arrest victims.
