If a heart attack is suspected, you should be admitted to hospital immediately. You will usually be admitted to an acute cardiac care unit (ACCU) so the diagnosis can be confirmed and treatment begin.
Treating a heart attack
There are two main treatment options for people with the most serious form of heart attack; an ST segment elevation myocardial infarction (STEMI).
Complications of a heart attack
Potential complications arising from a heart attack can vary widely, from mild to life threatening.
