Purpose: Key pharmacotherapeutic modalities and considerations for the patient with ST-elevation myocardial infarction (STEMI) across the critical initial phases of care are reviewed.

Summary: Despite established value in the emergency department (ED), cardiac care, and intensive care settings, there is currently little published literature describing or supporting clinical pharmacist roles in the acute management of STEMI. The high-risk period from hospital presentation through revascularization and stabilization involves complex pharmacotherapeutic decision points, many operational medication needs, and multiple layers of quality oversight. While rife with opportunities for pharmacists to optimize care, this timeframe appears inconsistently targeted by clinical pharmacy services, which may halt after ED evaluation and then resume upon postcatheterization cardiac unit admission. Herein we review the key pharmacotherapeutic modalities and considerations for the patient with STEMI across the critical initial phases of care. These include supportive therapies prior to revascularization, the host of antithrombotics involved in revascularization by percutaneous coronary intervention and/or fibrinolysis, and other periprocedural medications. Important practice guidelines and clinical resources are summarized from the clinical pharmacist perspective, and roles and responsibilities of the responding pharmacist are suggested. A companion article will extend the review to periprocedural adverse event management, key early decision-making regarding long-term risk reduction, and pharmacist involvement in institutional quality improvement efforts. We aim to support inpatient pharmacy departments in advancing clinical services for this critical patient population, and we call for further research delineating pharmacist impact on patient and institutional STEMI outcomes.

Conclusion: Patients presenting with STEMI rapidly traverse multiple phases of care and receive a host of antithrombotic and supportive medications during acute management, presenting many important pharmacotherapeutic decision points and roles for pharmacists.
