Heart ultrasound may predict defibrillator need after heart attack
NCT ID NCT05285631
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a special heart ultrasound (speckle tracking echocardiography) can predict which patients need an implantable defibrillator (ICD) after a large heart attack. Researchers followed 200 patients for 90 days to see whose heart function stayed low enough to qualify for an ICD. The goal is to identify high-risk patients earlier so they can get life-saving devices sooner.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors identify high-risk patients earlier after a heart attack, potentially preventing sudden cardiac death.
- What could go wrong
- This is a completed observational study, not a treatment trial. The prediction models need further validation before they can be used in routine care.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age between 18 and 80 years. Both genders are eligible. * Patients with diagnosis of an acute anterior STEMI and revascularized with successful primary percutaneous coronary intervention (PCI) within 24 hours. * LVEF \< 40 % assessed by Bi-plane Simpsons rule within 48 hour post PCI. Exclusion Criteria: * ● Refusal to participate in the study. * Patients with existing ICD or pacemakers. * Qualifying ICD for secondary prevention. * Known to have LVEF ≤ 40% prior to the index MI. * Previous PCI to Left anterior Descending artery (LAD). * Previous or being scheduled for CABG within ≤ 3 months. * Known to have limited life expectancy (less than 1-year) prior to the index MI. * Pregnant or lactating women.
