Heart attack

After someone has suffered a heart attack, their body replaces the damaged heart muscle tissue with non-beating scar tissue, compromising the heart's function. A new injectable biomaterial, however, may help the heart heal better.

When someone suffers a heart attack, their heart is left permanently scarred and thus less capable of pumping blood. According to a new study, however, a protein injection could help undo such damage.

A new study supported by the National Institutes of Health questions the belief that high levels of "good" cholesterol can decrease a person's risk of heart attack. The findings suggest the assumption may not hold true for people of all racial backgrounds.

Research has found over the course of the pandemic heart attack deaths have spiked alongside COVID-19 infection waves. The findings cannot causally link the heart attacks to COVID, however prior studies have found SARS-CoV-2 infections can damage the heart.

A large international clinical trial has found combining three common heart disease drugs into the one pill is significantly more effective at preventing cardiovascular events and death compared to administering each of the medicines separately.

Scientists have demonstrated a new system that can restore crucial molecular and cellular functions in pigs one hour after death. The experiments could help widen the organ transplantation pool and may even lead to new treatments for heart attacks.

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.

A robust new study led by researchers from Stanford University has found THC can trigger inflammation in blood vessel cells, and the researchers call for medical marijuana users to be aware of potential cardiovascular risks.

Researchers have discovered a new potential way to prevent arteries clogging, and as such reduce the risk of heart attacks and strokes. The technique involves ramping up a cleaning process that naturally slows down as we age.

In phase 1 trials, an RNA gene therapy has shown promise for reducing levels of a lipoprotein associated with a high risk of heart disease. The treatment could help fight a form of the disease that can’t currently be treated through lifestyle changes.

New research has discovered a distinct circadian mechanism within heart cells that influences how cardiac activity shifts across 24-hour periods. The findings offer clues to why shift workers are at higher risk of heart problems.

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.
