Using plasma exosomes to predict heart remodeling in STEMI patients

ExosoMe as Integrative Tool for pRognostic Stratification of Adverse Cardiac remodeLing in stEmi Patients: the MIRACLE Study

Observational Centro Cardiologico Monzino · NCT06070974

This study is trying to see if tiny particles in the blood can help doctors find out which patients are at higher risk for heart problems after a heart attack.

What this trial studies

This multicenter observational study aims to determine if plasma exosomes can identify patients at high risk of adverse cardiac remodeling following ST-elevation myocardial infarction (STEMI). Enrolled patients will undergo blood collection and cardiovascular magnetic resonance imaging three days after successful percutaneous coronary intervention (PCI). The study seeks to correlate exosome profiles with the severity of myocardial infarction to enhance early patient management and reduce future cardiovascular risks. By exploring the potential of exosomes as biomarkers, the study addresses a critical gap in the current understanding of post-STEMI patient outcomes.

Who should consider this trial

Good fit: Ideal candidates include individuals experiencing chest pain indicative of myocardial ischemia and who have undergone successful PCI within 12 hours of symptom onset.

Not a fit: Patients with a history of previous myocardial infarction or those with contraindications to cardiovascular magnetic resonance imaging may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved early identification of patients at risk for adverse cardiac remodeling, allowing for timely interventions.

How similar studies have performed: While the use of exosomes as biomarkers is a relatively novel approach, previous studies have shown promise in their ability to reflect disease pathophysiology in myocardial infarction.
