Study summary

Contemporary data are lacking regarding the management of left ventricular thrombus (LVT) developed after ST segment elevation myocardial infarction

Read the detailed description

Left ventricular thrombus (LVT) is a commom complication after ST segment elevation myocardial infarction (STEMI), reperfusion therapy have reduced the incidence of LVT, however, about 6% of all STEMI patients will develop LVT. the risk of LVT development in anterior STEMI with reduced LVEF are as high as 20%. Although current guideline recommend anti-coagulation therapy, but the evidence still based on observational data, there has been inconsistency with the benefit of the coagulation therapy, give the significant increased bleeding risk by superimpose anti-coagulation therapy to the dual anti-platelet therapy. especially in the era of more potent anti-platelet P2Y12 inhibitor widely used clinical. the mechanism of LVT is different from that of the atrial fibrillation in which the risk of systemic embolism is persistent, coagulation bring absolute clinical benefit for high risk patients. however, for LVT developed following STEMI tend to be temporary, majority of thrombus resolve within 1-3 months after STEMI event. more likely a reflection of coagulation system in response to the necrosis of infarct myocardium. The optimal management in LVT after STEMI warrants further exploration. the desiring of randomized controlled clinical trial to compare dual anti platelet + anti-coagulation and dual anti-platelet without anti-coagulation in patient LVT are justified.

Inclusion criteria

Established ST segment elevation myocardial infarction within 7 days Left ventricular thrombus (LVT) is detected by either cardiac magnetic resonance (CMR) or TTE.

Ongoing treatment with dual anti- therapy according to ESC/AHA guidelines at the time of randomization

Exclusion criteria

Exclusion Criteria:

Clinically or hemodynamically unstable planed major surgeon such as CABG or Valve replacement within next 12 months Concomitant condition that requires anti- coagulation therapy, such as AF, DVT.

Any of anticoagulant therapy History of intracranial hemorrhage; Woman who is currently pregnant, or breastfeeding serious impaired renal and liver functions less than 1 year can not provide consent

Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

What researchers measure

Primary outcomes

  1. Percentage of participants with the first occurrence of Stroke and other systemic embolism

    The percentage of participants with the first occurrence of Stroke and other systemic embolism were evaluated.

    Time frame: 12 months

Secondary outcomes

  1. Composite major adverse events

    The incidence of a composite adverse events, including all cause mortality, recurrent myocardial infarction, ischemic stroke and other systemic embolism

    Time frame: 12months

  2. LVT resolution

    the LVT resolve will be determined monthly by follow-up imaging examination (Echo cardiograph or Cardiac magnetic resonance). The percentage of LVT resolve at 3 months will be calculated for each group.

    Time frame: 12 months

  3. Total LVT present time

    LVT will be followed every month in the first 3 months, every 3 months thereafter to determine the present of LVT by Echo cardiograph or Cardiac magnetic resonance.

    Time frame: 12 months

  4. Percentage of Participants With Clinically Significant Bleeding

    Clinically significant bleeding is a composite of Thrombolysis in Myocardial Infarction (TIMI) major bleeding, minor bleeding, and bleeding requiring medical attention (BRMA). TIMI major bleeding is defined as any symptomatic intracranial hemorrhage, clinically overt signs of hemorrhage (including imaging) associated with a drop in hemoglobin of greater than or equal to (\>=) 5 grams per deciliter (g/dL) (or when the hemoglobin concentration is not available, an absolute drop in hematocrit of \>=15 percent (%)). TIMI minor bleeding event is defined as any clinically overt sign of hemorrhage (including imaging) that is associated with a fall in hemoglobin concentration of 3 to less than (\<) 5 g/dL (or, when hemoglobin concentration is not available, a fall in hematocrit of 9 percent to \<15 percent). A BRMA event is defined as any bleeding event that requires medical treatment, surgical treatment, or laboratory evaluation, and does not meet criteria for a major or minor bleeding event.

    Time frame: 12 months

  5. Percentage of Participants With Thrombolysis in Myocardial Infarction (TIMI) Major Bleeding

    TIMI major bleeding is defined as any symptomatic intracranial hemorrhage, Clinically overt signs of hemorrhage (including imaging) associated with a drop in hemoglobin of \>= 5 g/dL (or when the hemoglobin concentration is not available, an absolute drop in hematocrit of \>=15 percent

    Time frame: 12 months

  6. Percentage of Participants With Thrombolysis in Myocardial Infarction (TIMI) Minor Bleeding

    TIMI minor bleeding event is defined as any clinically overt sign of hemorrhage (including imaging) that is associated with a fall in hemoglobin concentration of 3 to \<5 g/dL (or, when hemoglobin concentration is not available, a fall in hematocrit of 9 percent to \<15 percent

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started May 2023 (actual). Primary completion is estimated for Sep 2026, 40 months after the start.

Of 134 non-industry interventional studies with no phase under ST Elevation Myocardial Infarction, half reached primary completion within 38 months of starting (the median), counting those still running; a quarter within 19 and three quarters within 64. This study's planned 40 months is close to that.

Counting every sponsor, half of 143 studies reached it within 38 months; a quarter within 19 and three quarters within 64.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 1, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
