Heart attack

Heart attack patients often need replacements for damaged arteries. In a new proof-of-concept study, scientists knitted a prototype graft out of hybrid synthetic and biological yarn, helping the patients own cells grow and repair the artery.

New research is suggesting a simple saliva test can detect the presence of a protein biomarker known to signal the occurrence of a heart attack in just 10 minutes, potentially accelerating the speed at which patients can be diagnosed and treated.

Heart attacks are a leading cause of death, largely because damage caused by one can lead to more. Now researchers at Rice University have developed a new way to repair heart tissue and reduce scarring, by implanting capsules loaded with stem cells.

We've already heard about genetically manipulated types of rice that are drought-resistant and antioxidant-rich. A new one, however, could potentially save the lives of people with high blood pressure.

A new study has delved into the impact of gut bacteria on cholesterol levels, detailing the "remarkable effects" of the introduction of a set of molecules that shift the balance of bacterial species in a way that prevents thickening of the arteries.

The human heart lacks the ability to replenish cells. But now, researchers at the University of Texas Southwestern have uncovered a suite of proteins in mice that could be switched off to induce heart cells to begin replicating again temporarily.

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.

Cardiac patches are designed to help regenerate healthy heart tissue after the injury, and scientists at North Carolina State University have now developed an “off-the-shelf” version they say overcomes some of the dangers of other approaches.

A newly published study from researchers at Brigham and Women’s Hospital in Boston is suggesting irregular sleep patterns, such as inconsistent bedtimes from day to day, can potentially double a person’s risk of developing cardiovascular disease.

Atherosclerosis is a disease where fatty plaques build up in the arteries, increasing risk of heart attack or stroke. But now, researchers at Oxford have found a protein that could be targeted in new prevention drugs for these deadly buildups.

Atherosclerotic plaque-deposits on the inner walls of arteries are a frequent cause of heart attacks and strokes. A newly-developed nanoparticle could help minimize those deposits, as it prompts the body's own cells to "eat" them.

Even if one survives a heart attack, the formation of thick scar tissue can increase the chance of heart failure. Now researchers have found a way to improve the quality of scar tissue in animal models, resulting in improved heart function.
