About this study
Official title: Incremental Utility of Myocardial Contrast Echocardiography for the Assessment of the Infarct Related Artery and Risk Area in Patients With Non-ST Segment Elevation Myocardial Infarction.
The goal of this study will be to assess the incremental benefit of myocardial contrast echocardiography for the assessment of regional wall motion abnormalities and infarct-related artery in patients presenting with their first NSTEMI.
Read the detailed description
Patients presenting with NSTEMI who are scheduled to undergo elective cardiac catheterization and coronary angiography with primary PCI will be selected for participation in the study. The patients will undergo a clinically indicated resting non-contrast echocardiogram to assess LV function and regional wall motion. They will then undergo contrast echocardiography with bolus injection of Optison™ contrast to reassess LV ejection fraction, improve LV opacification and assess regional wall motion abnormalities. Finally, they will be given a continuous infusion of Optison™ and will have assessment of myocardial perfusion of each of the 17 myocardial segments using low mechanical index continuous imaging of the myocardium and blood pool.
Two expert echocardiographers will be asked to review in a blinded fashion the non-contrast echocardiogram, interpret the ejection fraction, and assess regional wall motion abnormalities in each of the 17 myocardial segments. They will then be asked to predict the infarct-related artery (either LAD, LCx, or RCA).
A proposed sample size of 100 patients presenting to Cedars-Sinai Medical Center with their first NSTEMI will be studied. Based on hospital volume, approximately 4-5 NSTEMI patients present to Cedars-Sinai on a weekly basis, of which at least 2 will be eligible per week. Based on this trend, we feel we can achieve the necessary sample size within 12 months.
Inclusion criteria will be patients aged 31-90 presenting with World Health Organization diagnosis of non-ST segment elevation myocardial infarction, which encompass 2 out of the following 3 criteria: a clinical history of chest pain unrelieved by nitroglycerin, ECG evidence of cardiac ischemia (ST segment depression or T wave inversion), and enzymatic evidence of myocardial infarction (elevation of TnI or CKMB). Patients should be clinically eligible for coronary angiography.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
EchocardiogramProcedure or surgery
- Contrast echocardiography with Optison for assessment of regional wall motion. This will be performed immediately following the resting echocardiogram by a sonographer specifically trained in myocardial contrast echocardiography.
- Contrast echocardiogram with Optison for assessment of myocardial perfusion. This will be performed using a continuous infusion of Optison using low mechanical index power-modulation imaging of the myocardium and blood pool. Myocardial perfusion will be assessed offline using video intensity analysis software.

What is being measured
The primary outcome is the main question the study is designed to answer.
Accuracy of determination of the infarct related artery as compared to the findings from clinically indicated coronary angiography
Patients presenting with NSTEMI who are scheduled to undergo elective cardiac catheterization and coronary angiography with primary PCI will be selected for participation in the study. The patients will undergo a clinically indicated resting non-contrast echocardiogram to assess LV function and regional wall motion. Immediately following, they will then undergo contrast echocardiography with bolus injection of Optison™ contrast to reassess LV ejection fraction, improve LV opacification and assess regional wall motion abnormalities. Finally, they will be given a continuous infusion of Optison™ and will have assessment of myocardial perfusion of each of the 17 myocardial segments using low mechanical index continuous imaging of the myocardium and blood pool.
Measured: Baseline: Immediately following resting echocardiogram at time of index STEMI and prior to cardiac cath.
Secondary outcomes (1)
Myocardial Segment Determination
The determination of the number of assessable myocardial segments and the number of assessable abnormal myocardial segments.
Measured: Baseline: Immediately following resting echocardiogram at time of index STEMI and prior to cardiac cath.

Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 18 Dec 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Accuracy of determination of the infarct related artery as compared to the findings from clinically indicated coronary angiography (time frame: Baseline: Immediately following resting echocardiogram at time of index STEMI and prior to cardiac cath.). 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 NCT02014701, which also lists 3 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 18 Dec 2013.
