The Contemporary Role of Beta Blockers in Patients With Acute Myocardial Infarction

• Conditions: Acute Coronary Syndrome
• Interventions: Drug: beta-blocker

• Registration Number: NCT04564365
• Lead Sponsor: Chongqing Medical University

Brief Summary

The use of beta blockers after acute myocardial infarction is a core component of drug therapy, but evidence is primarily derived from patients who did not receive reperfusion therapy and secondary prophylaxis.In contemporary times, the prognostic value of beta blockers in patients with acute myocardial infarction has been questioned, particularly in patients without reduced heart failure/ejection fraction after acute myocardial infarction.
