Brief Summary:
The study is aimed to optimized the dose-adjusted regimen of beta-blockers in patients with acute coronary syndrome by investigating therapeutic and curative results of target doses Beta-blockers using the dose-adjusted pathway of beta-blockers.

Condition or disease
Acute Coronary Syndrome

Layout table for study information
Study Type : Observational
Estimated Enrollment : 2200 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Real World Assessment of Effects of Beta-blockers on Patients With Acute Coronary
Actual Study Start Date : August 31, 2018
Estimated Primary Completion Date : December 31, 2021
Estimated Study Completion Date : July 31, 2022

Primary Outcome Measures :
  1. Major adverse cardiovascular and cerebrovascular events (MACCE) [ Time Frame: Within 1 year after surgery ]
    MACCE were defined as a composite of all-cause death, myocardial infarction (MI), unplanned target vessel revascularization (TVR), stent thrombosis (ST) and stroke.

Secondary Outcome Measures :
  1. Resting heart rate [ Time Frame: Within 1 year after surgery ]
    The resting heart rate of the body is the number of contractions of the heart that occur in a single minute while the body is at complete rest.

  2. Blood pressure (systolic & diastolic) [ Time Frame: Within 1 year after surgery ]
    Blood pressure (BP) is the pressure of circulating blood on the walls of blood vessels.

  3. Ejection fraction [ Time Frame: Within 1 year after surgery ]
    Ejection fraction (EF) is the volumetric fraction of fluid (usually blood) ejected from a chamber (usually the heart) with each contraction (or heartbeat).

  4. Serum norepinephrine [ Time Frame: Within 1 year after surgery ]
    Norepinephrine is a neurotransmitter that is secreted in response to stress.
