Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
