About this study

Official title: Utility of 2D Strain Echocardiography in Triage of Patients With Chest Pain in the Emergency Department

Background: Chest pain (CP) and suspected heart attack is the second most frequent complaint among patients presenting to the emergency department (ED). Present workup involves in-hospital observation for 6 - 48 hours and requires significant resources including imaging tests, some of which are invasive and involve radiation and radio-contrast agents, which can be toxic to the kidney.

CP can result from impaired blood supply to the heart muscle, which may result in impaired contraction of the heart that persists for several days. Bedside echocardiography with semi-automated speckle tracking strain analysis (2D strain) is a novel promising noninvasive tool for the evaluation of heart muscle contraction. 2D strain can be useful for evaluating patients with CP, since it can accurately detect minor impairment in heart muscle contraction that can identify patients with coronary artery disease (CAD) and impending heart attack (coronary arteries are the arteries supplying blood to the heart muscle).

Working hypothesis and aims: The investigators hypothesize that a bedside echo study with normal 2D strain may allow quick and safe ruling out of a heart attack and significant CAD disease as the cause of CP.

The main aim of the study is to validate the investigators preliminary findings in a large number of patients in order to establish whether a normal 2D strain can safely rule out a heart attack or life threatening CAD.

Methods: In a large multi-center study 1200 patients presenting to the ED with acute CP of an unclear cause will undergo echocardiography as close as possible to presentation and not more than 24 hours from cessation of pain. Patients will undergo standard workup by the ED physicians. Standard echocardiographic findings, but not the 2D strain analysis, will be made available to the attending physician. Data from discharge letters, ECGs, blood tests, stress tests, nuclear imaging, heart CT and heart catheterization will be collected. A 6-month follow-up telephone interview will be performed to collect data on survival, heart attacks, re-hospitalization and revascularization (opening heart vessels blockages). 2D strain analysis will be performed off-line in a central laboratory to evaluate the ability of 2D strain to distinguish between patients with CP from heart disease and patients without life threatening heart disease that can be early released home safely.

Expected results: The investigators expect, based on the investigators previous experience, that patients with normal 2D strain will have a very low probability of a heart attack and significant CAD. The investigators further expect these patients to have an excellent 6-month prognosis. This will allow their early and cost-effective discharge.

Importance and Probable implications to Medicine: Reduction in ED patient load and a decrease in unnecessary hospitalizations for CP. Cost and resource savings and elimination of unnecessary imaging studies, some of which are invasive or involve radiation and contrast agents.

Questions about this trial

What is this clinical trial studying?

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 Oct 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Acute coronary syndrome (time frame: 1 week). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01163019, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Oct 2014.
