ICD-Code I21.9: Acute myocardial infarction, unspecified
You had a heart attack.
The heart muscle is supplied with oxygen-rich blood via the coronary arteries. The coronary arteries are blood vessels that run around the outside of the heart.
A heart attack involves parts of the heart not getting enough oxygen-rich blood. As a result, the affected heart tissue gets damaged or dies.
A heart attack can cause sudden pain in the chest or arm. They may sweat or feel nauseous. The heart may no longer be working properly. One can then have breathing difficulties and be seriously ill.
