Real World Assessment of Effects of Beta-blockers on Patients With Acute Coronary

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 120 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Study Population

Patients with acute coronary syndrome

Description

Inclusion Criteria:

  • Age ≥ 18 years
  • Patients diagnosed as acute coronary syndromes including acute ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevated acute coronary syndrome (NSTE-ACS)
  • Patients or whose legal representatives signed written informed consent form

Exclusion Criteria:

Patients should been excluded if they meet any of the following exclusion criteria:

  • Patients with contraindications to the application of beta blockers, including: 1) cardiogenic shock or heart failure (Killip grade > II level);2) sick sinus syndrome; 3) II degree atrioventricular block;4) unstable decompensation of cardiac failure (pulmonary edema, hypotension or low perfusion); 5) symptomatic hypotension or bradycardia (heart rate<50 beats/min, blood pressure<90/60mmHg); 6) contraindications to beta blockers or allergy to any ingredient of beta blocker; 7) active asthma should be treated by inhalation preparation treatment
  • Pregnant or lactating women
  • Patients without signed written informed consent
  • Patients who was considered by the researcher inappropriate to participate in this study (for example, patients with a higher risk of cardiogenic shock, etc.)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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.
Within 1 year after surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
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.
Within 1 year after surgery
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.
Within 1 year after surgery
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).
Within 1 year after surgery
Serum norepinephrine
Time Frame: Within 1 year after surgery
Norepinephrine is a neurotransmitter that is secreted in response to stress.
Within 1 year after surgery

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 31, 2018

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Anticipated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
