About this study
Official title: ReModeling in ST-elevation myocARrdial Infarction: a Comparison of Left VEntricuLar Functions in Long-term Follow-up Among STEMI Patients: The MARVEL Study
Patients diagnosed with STEMI who underwent pPCI were included in this study. The investigators collected comprehensive data on each patient's status, including laboratory findings such as NT-proBNP, troponin levels, and inflammatory profile assessed by leukocyte count, C-reactive protein, interleukin-1, and interleukin-6. Additionally, electrocardiographic and echocardiographic features, details of the coronary intervention procedure, hospital stay duration, complications, and medical treatments were recorded.
Comprehensive transthoracic echocardiograms (TTE) were performed at admission and before discharge. Myocardial tissue characterization was conducted by cardiac magnetic resonance (CMR) imaging before discharge, assessing intramyocardial hemorrhage (IMH), microvascular obstruction (MVO), infarct size (IS), area at risk (AAR), salvaged myocardium, and salvage index.
At the six-month follow-up, laboratory tests, CMR imaging, and TTE were repeated, along with a thorough clinical evaluation. LVR was defined by one of the following criteria: a 20% increase in end-diastolic volume by TTE or 12% by CMR, a 15% increase in end-systolic volume, a sphericity index greater than 42% (CMR only), the emergence of new concentric hypertrophy, or a reduction greater than 10% in left ventricular ejection fraction (LVEF).

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 17 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does the primary outcome measure?
Remodeling (time frame: 36 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Jul 2025.
