Acute coronary syndrome: pharmacotherapy

Area of Science:

• Cardiology
• Emergency Medicine
• Pharmacology

Background:

• Acute coronary syndrome (ACS) encompasses a range of cardiac conditions, from unstable angina to ST-segment-elevation myocardial infarction.
• In emergency medical services (EMS), ACS management includes patients with symptoms suggestive of cardiac origin, confirmed ischemia, or myocardial infarction via electrocardiogram.
• Prehospital ACS care considers patients with prior cardiac events or known cardiac disease presenting with symptoms.

Framework:

• Pharmacologic management of ACS relies on three key drug classes: anticoagulants, hemodynamic stabilizers, and analgesics.
• Agents reviewed include aspirin, GPIIb/IIIa inhibitors, heparins, fibrinolytics, beta-blockers, calcium antagonists, nitrates, and morphine.
• Efficacy of these agents is established in hospital settings, with ongoing research in prehospital environments.

Implementation:

• Prehospital drug use depends on patient selection, need for immediate intervention, and ease of administration.
• EMS personnel expertise and cost-effectiveness are critical factors in implementing prehospital therapies.
• A consensus review assessed indications, prehospital applicability, and current use of various pharmacologic agents.

Implications:

• Optimizing prehospital pharmacotherapy can improve outcomes for patients with acute coronary syndrome.
• Evidence-based selection of medications is crucial for effective emergency cardiac care.
• Further research into prehospital efficacy will refine treatment protocols for ACS.
