What is the primary treatment for a patient presenting with ST elevation myocardial infarction (STEMI)?

In the case of a patient presenting with ST elevation myocardial infarction (STEMI), the primary treatment option is either percutaneous coronary intervention (PCI) or thrombolytic therapy.

PCI is a minimally invasive procedure that involves the use of a catheter to open the blocked coronary arteries, often employing a stent to ensure the artery remains open. This approach is preferred in many hospitals due to its effectiveness in quickly restoring blood flow to the heart muscle, which is crucial for minimizing damage and achieving the best possible outcomes.

Alternatively, thrombolytic therapy involves administering medication to dissolve the blood clot that is obstructing the coronary artery. While this treatment is rapidly delivered and can effectively restore blood flow, it is generally considered when PCI cannot be performed in a timely manner or when it is not available.

The other options are not the primary treatments for STEMI. Coronary artery bypass grafting (CABG) is a surgical option that is usually reserved for cases where PCI is not feasible or in patients with multivessel disease. Aspirin is an important adjunctive therapy in the management of STEMI but does not directly address the blockage in the coronary arteries. Long-term anticoagulation therapy may be beneficial for certain patients but is not the first line
