About this study

Official title: Impact of Ischemic Post-conditioning During Primary Percutaneous Coronary Intervention on Left Ventricular Remodeling and Global Systolic Function in Patients Presenting With ST-Elevation Myocardial Infarction

Study will investigate \& compare the left ventricular remodeling \& systolic function between two groups of ST-elevation myocardial infarction undergoing primary per-cutaneous coronary intervention applying ischemic post-conditioning to one of them.

Read the detailed description

Among re-perfusion strategies for the management of ST-elevation myocardial infarction , primary per-cutaneous coronary intervention is the preferred one within 120 minutes from the first medical contact.However , restoration of the coronary blood flow can paradoxically reduce the beneficial effects of myocardial re-perfusion , a phenomenon known as myocardial re-perfusion injury.Ischemic post-conditioning has been described as a measure for myocardial salvage , performed by making cycles of briefly interrupted perfusion during the early moments of coronary re-flow.Post-conditioning may be performed immediately after the early re-flow by creating cycles of interrupted inflation \& deflation of the angioplasty balloon in patients undergoing primary per-cutaneous coronary intervention.In this study investigators aim to compare the left ventricular remodeling and global systolic function immediately \& 6 months after re-perfusion between two groups of 100 patients presenting with acute ST-elevation myocardial infarction, using ischemic post-conditioning in one group of patients undergoing primary per-cutaneous coronary intervention (n=50 patients) by making 4 cycles of repeated occlusion \& re-perfusion 30-second each by inflation/deflation of an appropriately sized per-cutaneous trans-luminal coronary angioplasty balloon.The other group will be investigated after re-perfusion by primary per-cutaneous coronary intervention without ischemic post-conditioning (n=50 patients)

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Primary per-cutaneous coronary interventionProcedure or surgery

    Patients presenting with ST-elevation myocardial infarction will undergo primary per-cutaneous coronary intervention including balloon angioplasty \& coronary stent deployment as needed +/- post-conditioning (for post-conditioning arm) making 4 cycles of repeated occlusion \& reperfusion 30-second each by inflation/deflation of an appropriately sized PTCA (percutaneous transluminal coronary angioplasty) balloon

Questions about this trial

What is this clinical trial studying?

A study testing Primary per-cutaneous coronary intervention in people with ST Elevation Myocardial Infarction and Ventricular Remodeling, run by Assiut University.

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 5 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 6 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

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?

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?

Left ventricular remodeling (time frame: Immediate-6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 6 Sep 2019.
