Optimal Strategy of Primary PCI for Left Main Coronary Artery Occlusion Induced AMI (OPTIMAL)

November 18, 2017 updated by: Shanghai Zhongshan Hospital

Optimal Strategy of Primary Percutaneous Coronary Intervention for Acute Myocardial Infarction Due to Unprotected Left Main Coronary Artery Occlusion

This study will compare clinical outcomes of immediate stent implantation with deferred stent implantation(4-10days after primary angiography) for patients presented with acute myocardial infarction due to left main coronary artery occlusion.

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.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Primary percutaneous coronary intervention for patients presented with acute myocardial infarction caused by left main coronary artery occlusion is associated with significantly higher mortality and risks of major cardiac adverse events. Deferred stent implantation may improve prognosis of primary PCI through reducing distal embolization and no-reflow phenomenon. There is no randomized clinical trial focuses on the effect and outcome of deferred stent implantation on primary PCI for left main coronary artery occlusion in contrast with conventional strategy.

This prospective, multicenter, randomized trial is aimed to compare immediate stenting with deferred stenting for LM-AMI with 30 centers in China involved. We hope to determine whether deferred stenting is superior to conventional strategy for primary PCI of AMI caused by left main coronary artery occlusion in improving long-term clinical outcomes and cardiac function.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

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

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
