How heart attacks damage heart muscles

 

Recurrent heart attacks are so common these days in Uganda and across Africa. Studies in US show that about 20 per cent of people who suffer from heart attacks experience additional attack within a period of six weeks.

Sometimes a heart attack damages the heart muscle so much that the hearts can no longer function properly. Heart failure is a condition in which the heart can no longer pump adequate supply of blood to your body, resulting in shortness of breath and fatigue. In some cases, the damage may be severe, resulting into chronic heart failure.

Dr Emmy Okello, a cardiologist at the Uganda Heart Institute in Mulago says that the valves in the heart which let blood in and out may be damaged when a person suffers a heart attack, causing blood to leak in the wrong direction.
