What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Left Ventricular End Diastolic Volume (LVEDV)

    Left ventricular end diastolic volume (LVEDV) was measured by echocardiogram. Change was measured as Month 18 LVEDV minus baseline LVEDV.

    Per protocol, change in LVEDV is compared between Pooled Pacing (Single site + Dual Site) and Control.

    Measured: Baseline - 18 Month Follow Up Visit

Secondary outcomes (7)
  1. Safety of Implanting a Cardiac Resynchronization Therapy With Defibrillator (CRT-D) Device Within 10 Days of Myocardial Infarction (MI), as Measured by the Rate of Reported Adverse Events

    Survival estimates at 18 months post-implant for time to first following events: (a) System Related Adverse Event (b) System Related Complication (c) Procedure Related Adverse Event (d) Procedure Related Complication and (e) System Related or Procedure Related Complication.

    Measured: 18 months post-implant

  2. Frequency of Hospitalization for Cardiovascular Events

    Number of hospitalizations related to cardiovascular events.

    Measured: Baseline - 18 Month Follow Up Visit

  3. Change in New York Heart Association (NYHA) Functional Class

    The New York Heart Association (NYHA) score classifies patients' heart failure according to the severity of their symptoms. In particular, Class I: No limitation of physical activity. Class II: Slight limitation of physical activity. Class III: Marked limitation of physical activity. Class IV: Unable to carry on any physical activity without discomfort.

    NYHA change from baseline to 18-month visit. If a subject improved by one NYHA class or more (e.g. NYHA IV to NYHA II, or NYHA III to NYHA I, etc) from the baseline visit, the subject was classified as "Improved". Similarly for "Worsened" (e.g. subject does not have heart failure to NYHA I, NYHA I to NYHA II, etc.). If the subjects' NYHA Class is not different than baseline, then the subject was classified as "No Change".

    Per protocol, change in NYHA is compared between Pooled Pacing (Single site + Dual Site) and Control.

    Measured: Baseline - 18 Month Follow Up Visit

  4. Change in 6-minute Walk Test Distance

    Change in 6-minute hallwalk distance from 1-month visit to the 18-month visit.

    Change is defined as month 18 minus baseline.

    Per protocol, change in 6-minute walk test distance is compared between Pooled Pacing (Single site + Dual Site) and Control.

    Measured: 1 Month - 18 Month Follow Up Visit

  5. Change in Quality of Life

    Change in the Minnesota Living with Heart Failure (MNLWHF) questionnaire from baseline to the 18-month follow-up visit.

    Change is defined as month 18 minus baseline.

    Per protocol change in MNLWHF is compared between Pooled Pacing (Dual Site + Single Site) and Control.

    Measured: Baseline - 18 Month Follow Up Visit

  6. Incidence of Sudden Cardiac Death and Total Mortality

    Mortality rates (%) for the events (a) all-cause death and (b) sudden-cardiac death at 18 months post randomization. Calculated using Kaplan-Meier methods.

    Per protocol the comparison of mortality rates is between Pooled Pacing (Dual Site + Single Site) and Control.

    Measured: 18 Months post-randomization

  7. Linear Association Between Change in LVEDV and Selected Clinical Characteristics; Including Peak Creatinine Phosphokinase (CPK), Peak Troponin, Lead Location, Time From MI Onset to Implant, and Change in LV Volumes.

    Linear association between change in LVEDV from baseline to 18-month visit (i.e. ΔLVEDV) and the following clinical characteristics were assessed: age, days from MI to implant, gender, hypertension, hyperlipidemia, diabetes, peak CPK, infarct location, LV electrode in acceptable place, and baseline LVEF. In order to assess these linear associations, linear regression models were fitted for each of these clinical characteristics (separately). In particular, each linear regression model had baseline LVEDV and the clinical characteristic as covariates, and ΔLVEDV was the response variable.

    Variables resulting in statistical significant (p<0.05) are reported.

    Measured: Baseline - 18 Month Follow Up Visit

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Single Site Pacing and Dual Site Pacing in people with Acute Myocardial Infarction and Pacing Therapy, run by Medtronic Cardiac Rhythm and Heart Failure at 26 sites in 7 countries.

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 4 inclusion and 15 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 15 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 26 sites in United States, France, Germany, Hungary, Denmark and 2 more countries. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 15 Dec 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Change in Left Ventricular End Diastolic Volume (LVEDV) (time frame: Baseline - 18 Month Follow Up Visit). 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 NCT01213251, which also lists 1 linked publication.

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 15 Dec 2016.
