A person enters the emergency room of a hospital complaining of chest pain and shortness of breath. Upon receiving the test results, it is determined that the individual is experiencing a myocardial infarct. Anatomically speaking, what is going on during this condition, and what is the likely prognosis?
What will be an ideal response?
The goals of medical treatment are to limit the size of the infarct and prevent additional complications by
preventing irregular heart contractions, improving circulation with vasodilators, providing additional oxygen,
reducing the cardiac workload, and, when possible, eliminating the cause of the coronary blockage. Anticoagulants
can eliminate the formation of thrombi and clot-dissolving enzymes may reduce the extent of the damage if they
are administered within six hours of the heart attack.
