Long-term effects of heart attacks studied

29 June 2012

New research has suggested that heart attacks do more harm than just damaging heart muscle tissue.

A study conducted by an international team of researchers and led by Matthias Nahrendorf has highlighted the true problems of a heart attack.

On top of damaging heart muscle tissue as a result of the heart being void of its blood supply, the health condition also sets off an inflammatory cascade.

This causes underlying atherosclerosis to worsen, which can heighten the chance of another heart attack occurring in the future.

Mr Nahrendorf stated that his team's findings help to detail why people often suffer a second heart attack or a stroke.

He added: "The immune response to the infarct - tissue damaged by lack of oxygen - can accelerate the underlying disease by actually increasing the size and inflammation of the atherosclerotic plaque."

Earlier this week, researchers based at the University of Athens warned that a diet high in protein but low in carbohydrates increases the risk of people developing heart problems later in their lives.
