Interrupted blood flow to the heart can cause a myocardial infarction
1)The heart muscle is supplied with blood by the coronary arteries
2)This blood contains the oxygen needed by the heart muscle cells to carry out aerobic respiration.
3)If a coronary artery becomes completely blocked (e.g. by a blood clot) an area of heart muscle will be totally cut off from its blood supply, receiving no oxygen.
4)This causes a myocardial infarction - or heart attack
5)A heart attack can cause damage and death of the heart muscle
6)Symptoms include pain in the upper chest and body, shortness of breath and sweating
7)If large areas of the heart are affected complete heart failure can occur, which is often fatal
