Drinking four cups of coffee daily can be a healthy habit for the elderly. Coffee can increase the ability of the heart cells to function, as well as it is helpful in preventing heart attack.

Research conducted on mice suggests that coffee promotes the activity of a regulated protein in mitochondria. In this way it protects the cells attached to the heart from damage and increases their ability to function. Mitochondria are called the powerhouse of a cell.

This protein is known as P27. It works by stopping the cell cycle. This protein is present in mitochondria in the major cell types of the heart. Researchers say that mitochondrial p27 promotes the translocation of endothelial cells in these cells.

Endothelial cells protect the heart muscle cells from death and begin to transform fibroblast cells into cells with contractile fibers.

It is important for repairing all heart muscle after a heart attack or myocardial effusion and this happens in a person by drinking four cups of coffee.

Our results indicate a new way of working for caffeine, said Judith Handler of the Medical Faculty of Heinrich-Heine-University, Germany, which promotes the protection and repair of heart muscle through the action of mitochondrial p27 .
