How the microprotein BRICK1 repairs and protects the heart after a heart attack
Every year, more than 200,000 people in Germany suffer a heart attack. This is caused by blocked coronary arteries. As a result, part of the heart muscle is no longer supplied with sufficient blood and oxygen; the tissue ...

Microaxial flow pump does not improve outcomes for high-risk heart attack patients without cardiogenic shock: Trial
Using a microaxial flow pump prior to and during cardiac stenting procedures for patients with severe heart attacks who don't have cardiogenic shock does not significantly reduce heart damage. That is the major finding from ...

How RHOT proteins regulate energy supply in heart muscle cells
Our hearts beat around 100,000 times a day—and do so throughout our entire lives. They draw the energy for this from the mitochondria. As the "powerhouses of the cells," mitochondria produce 95% of adenosine triphosphate ...
