Influence of Beta Blockers on Prognosis in Patients With Acute Myocardial Infarction Complicated With Normal Ejection Fraction

• Conditions: AMI
• Interventions: Drug: Beta blocker

• Registration Number: NCT04485988
• Lead Sponsor: Chongqing Medical University

Brief Summary

To understand the effect of beta blockers on the prognosis of patients with acute myocardial infarction with preserved ejection fraction.

Detailed Description

The use of beta blockers is an important component of drug therapy for myocardial infarction, but in some exceptional cases, evidence-based evidence for their use is insufficient, and we seek to understand the prognostic impact of beta blockers on patients enrolled in long-term follow-up.
