A new study has examined the most common warning signs associated with a deadly out-of-hospital sudden cardiac arrest and found that symptoms differ significantly between the sexes. The researchers hope their study will improve survival rates and educa… Continue reading Warning signs of sudden cardiac arrest different for men and women
For all they do for us, our hearts aren’t very good at repairing themselves. So when a person suffers a heart attack, their blood pump is left with a large amount of scar tissue, which can impede the organ’s flexibility and thereby its function. Inspir… Continue reading Technique reverses heart attack damage by reprogramming scar cells
A new device designed to accurately and quickly sense whether a cardiac arrest patient also has a heart valve blockage that needs urgent treatment is now undergoing trials in Seattle.Continue ReadingCategory: Medical, ScienceTags: University of Washing… Continue reading New wrist sensor could save heart attack patients critical time in ER
Atrial fibrillation (AF or AFib) is the most common type of heart arrhythmia, affecting millions of people worldwide. Researchers have now developed a new procedure that shows great promise as a safe, quick and effective alternative to existing surgica… Continue reading Safe, effective new procedure to surgically treat common arrhythmia
Researchers at the University of Houston 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 … Continue reading mRNA treatment repairs mouse hearts to “near normal” after heart attack
Researchers from The Mount Sinai Hospital 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 potentially predicts death… Continue reading Newly discovered biomarker predicts COVID-19 death days in advance
Scientists at the Washington University School of Medicine 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 … Continue reading Radiation to the heart corrects arrhythmia by reactivating younger state
Drones may prove to be a more expedient means of delivering many items, but a number of research projects have demonstrated that dropping defibrillators off to heart attack victims could have life-saving consequences. A new study from a Swedish team of… Continue reading Real-world tests show life-saving potential of defibrillator drones
Unfortunately for heart attack patients, heart cells don’t naturally replenish, so this vital organ stays permanently damaged. But now, Cambridge researchers have stumbled onto a gene that appears to trigger heart cell regeneration – and they did so by… Continue reading Cancer study stumbles onto potential way to regenerate heart cells
People living in the hottest places on Earth could be up to three times as likely to die from a heart-related cause, according to a newly-published study. Global warming due to climate change has the potential to further worsen the heat-stress problem,… Continue reading Risk of heart-related death may triple in extreme heat environments
