Which medication should be administered before obtaining the ECG in a patient with ischemic chest pain?

In the scenario of a patient presenting with ischemic chest pain, administering aspirin before obtaining an ECG is critical. Aspirin has antiplatelet properties that play a significant role in the management of acute coronary syndrome (ACS) and can help reduce the risk of further clot formation in the coronary arteries. Chewing the aspirin facilitates faster absorption and onset of action, which is essential in the acute setting to mitigate myocardial injury.

The administration of aspirin is generally prioritized in the acute management of chest pain, as it directly addresses one of the underlying issues of ischemic pain—thrombus formation. Although other options may also be used in the management of ischemic chest pain, their timing and administration are typically based on specific clinical scenarios and patient responses. For example, nitroglycerin is used to relieve chest pain by decreasing myocardial oxygen demand, but it is not typically prioritized before the ECG in clinical practice because it can sometimes obscure diagnostic findings on the ECG. Morphine is also utilized for pain control, especially for severe chest pain, while heparin is indicated for anticoagulation but is generally administered after further assessment and often not before initial diagnostic steps like an ECG.

Thus, prioritizing aspirin in this context supports the immediate need to reduce cardiac event
