Scientists trying to find ways to regenerate a damaged heart have shed more light on the molecular mechanisms that could one day make this a reality. Whilst other organs such as the liver can regenerate, the heart muscle has very little ability to do so after suffering damage, such as a heart attack.
In the womb the body is able to produce heart muscle cells but soon after birth it effectively stops producing them.
New research shows that drinking one 16-ounce energy drink can increase blood pressure and stress hormone responses significantly. This raises the concern that these response changes could increase the risk of cardiovascular events.
