Heart attack
-
Minute differences in the blood pressure between each arm aren’t cause for concern, but there is a point at which variances could represent cardiovascular trouble, and an expansive international study has shone new light on where that point lies.
-
A phase 2 clinical trial of a cholesterol-reducing drug called evinacumab has reported promising results. In patients with extremely high cholesterol, the drug was able to reduce levels by about half, compared to a placebo.
-
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.
