A heart attack is when the blood supply to an area of the heart is cut off. This is usually by a blocked vessel that supplies the heart. A heart attack is a crushing central chest pain that lasts more than 20 minutes, and there is often sweating, nausea and shortness of breath at the same time.
Hospital testing confirms whether you have had a heart attack or not, and management afterwards depends on these tests. The most important things in management after a heart attack are changing your lifestyle; so stopping smoking, reducing your blood pressure if it is high, doing more exercise and improving your diet. It is likely that you will be put on drugs such as aspirin or warfarin too.
If you are mainly concerned about the high costs of being in hospital, choose a policy with full in patient and day patient treatment costs covered.
