Subarachnoid haemorrhage

Myocardial infarction, commonly known as heart attack, occurs when blood flow to a part of the heart stops, causing damage to the heart muscle. 

The heart muscles need oxygen to survive. When the blood supply carrying the oxygen to the heart muscles is blocked due to the buildup of plaque (fatty substances) within the arteries, it leads to damage of the muscles. If the blood flow to the heart is not restored quickly it can cause permanent damage to the muscles, leading to a heart attack.

Myocardial infarction is one of the leading causes of mortality worldwide. The symptoms of a heart attack include chest pain, discomfort in the back, sweating, nausea, vomiting, shortness of breath. In case of a suspected heart attack, the person should be given aspirin and rushed to a hospital immediately. One should not wait for symptoms to settle. The earlier the person is rushed to the hospital, the better are the chances of survival.

A heart attack can be treated with medications and in some cases, surgery might be required. The chances of a second heart attack can be prevented with simple lifestyle modifications, regular check-ups and medications.
