Safety of Beta-Blocker Administration in STEMI Patients With Risk Factors for Cardiogenic Shock.

Beta-blockers are recommended in the first 24 hours after ST-segment elevation myocardial infarction (STEMI) except in those at risk of cardiogenic shock. This retrospective cohort study aimed to assess if early beta-blocker use was associated with cardiogenic shock development in STEMI patients. Cardiogenic shock was assessed in adult patients with STEMI undergoing percutaneous coronary intervention (PCI) with guideline defined risk factors for shock (age above 70 years, systolic blood pressure below 120 mmHg, and heart rate above 120 bpm or below 60 bpm) who did or did not receive a beta-blocker within 24 hours of PCI.

A Retrospective Review of Cardiogenic Shock Development in Patients With ST-Elevation Myocardial Infarction and Percutaneous Coronary Intervention Receiving Early Beta-Blockers.

Beta-blockers (BBs) have proven to improve morbidity and mortality in patients after an ST elevation myocardial infarction (STEMI). Guidelines suggest initiating a BB within 24 hours, except in those with risk factors for developing cardiogenic shock, although published literature is conflicting regarding the true association of these risk factors with shock. This retrospective cohort study aimed to assess whether the presence of defined risk factors was associated with cardiogenic shock after early BB administration in patients with a STEMI and percutaneous coronary intervention.
