Global Strain and Mechanical Dispersion May Predict Death and Ventricular Arrhythmias Better Than Ejection Fraction

September 16, 2020 updated by: Thor Edvardsen, Oslo University Hospital

Improved Prediction of Clinical Outcome With the Use of Global Strain and Mechanical Dispersion in Patients With Myocardial Infarction and Heart Failure

The aim of the study is to investigate if global strain and mechanical dispersion may predict death and ventricular arrhythmias better than ejection fraction(EF) in patients with myocardial infarction and heart failure regardless of cause.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

  1. The main aim of this study is to investigate if global strain and mechanical dispersion may predict death and ventricular arrhythmias better than left ventricular ejection fraction in patients with myocardial infarction and heart failure.
  2. In patients who receive internal cardioverter defibrillator(ICD) the main aim is to investigate if mechanical dispersion may predict ventricular arrhythmias better than EF.

3) No interventions,only evaluation of the measurements obtained with transthoracic echocardiography.

4) Follow up for 3 years

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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
Ventricular arrhythmia and death after acute myocardial infarction or heart failure.
Time Frame: 3 years
Arrhythmic events during follow-up are defined as documented sustained ventricular tachycardia, ventricular fibrillation, and SCD. Survival is assessed by medical charts if patients are within the uptake area of the hospital and by the Norwegian death registry Folkeregisteret.
3 years

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.
