The final extent of cardiac damage after an acute myocardial infarction (AMI) is dependent upon:
1. Reperfusing the ischemic zone.
2. The client's ethnicity.
3. The client's gender.
4. Development of heart block.
Reperfusing the ischemic zone.
Rationale: Surrounding the area of infarction is the zone of injury and the zone of ischemia. These zones are made of potentially viable tissues. They can become necrotic and die, or be reperfused and remain functional. The goal of treatment for an AMI is to establish reperfusion as early as possible to prevent necrosis and salvage the myocardium. The client's ethnicity does not impact the final extent of cardiac damage, nor does the client's gender. Developing a heart block does not impact cardiac damage.
