Dangerous heart rhythms after a heart attack

Ventricular Arrhythmias in the Acute Phase of Myocardial Infarction: ADVERSE MI Study

Observational Poitiers University Hospital · NCT07517523

This study will see how survival and treatment differ for adults who develop sustained ventricular tachycardia or ventricular fibrillation during a heart attack, comparing events that occur within 48 hours to those that occur later.

What this trial studies

This is a multicenter retrospective chart review of adults with sustained ventricular arrhythmias occurring during the acute phase of an acute myocardial infarction at several French university hospitals between January 1, 2012 and April 14, 2024. Investigators will collect clinical characteristics, management steps (including device therapy and other treatments), and outcomes up to and after hospital discharge. The primary analysis compares post-discharge mortality for arrhythmias occurring within 48 hours versus after 48 hours of the index infarct. Sensitivity analyses will examine differences by arrhythmia subtype (ventricular fibrillation versus ventricular tachycardia), presence of concomitant heart failure, and ST-elevation versus non-ST-elevation myocardial infarction.

Who should consider this trial

Good fit: Adults (age ≥18) treated for an acute myocardial infarction between January 1, 2012 and April 14, 2024 who experienced a sustained ventricular tachycardia or ventricular fibrillation during the index hospitalization before discharge.

Not a fit: Patients who did not experience a sustained ventricular arrhythmia during the acute MI, who were treated only as outpatients, or who are under 18 would not be included and are unlikely to directly benefit from this analysis.

Why it matters

Potential benefit: If successful, the results could clarify timing-related risks and help refine recommendations for post-MI management such as timing of ICD placement to improve survival decisions.

How similar studies have performed: Previous evidence is limited and guideline recommendations about ICD placement after post-MI ventricular fibrillation rely on sparse retrospective data, so this area remains under-tested without definitive prospective trials.
