Long-term changes in left ventricular function after STEMI
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
Run by University of Pisa · NCT07041840 · Data updated 2026-11-12
We will test whether detailed heart imaging and blood tests can track long-term changes in heart structure and function in people who had a STEMI treated with primary PCI.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults who had a STEMI treated with primary PCI and who can safely undergo CMR imaging.
✕Probably not a fit
Patients who cannot have CMR (for example due to incompatible implants or severe claustrophobia) or who have other types of myocardial infarction may not benefit from the protocol.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Patients with STEMI treated with primary percutaneous coronary intervention were followed prospectively with comprehensive clinical data, serial blood biomarkers (NT-proBNP, troponin, leukocyte count, CRP, IL-1, IL-6), electrocardiography, transthoracic echocardiography at admission and before discharge, and cardiac magnetic resonance imaging before discharge and at six months. CMR was used to characterize intramyocardial hemorrhage, microvascular obstruction, infarct size, area at risk, and salvaged myocardium, while echocardiography provided serial volumetric and ejection fraction measurements. Left ventricular remodeling (LVR) was defined by predefined changes in end-diastolic and end-systolic volumes, sphericity index, new concentric hypertrophy, or a drop in LVEF. The protocol excluded patients with contraindications to CMR and was conducted at the University of Pisa (Cisanello Hospital) with a six-month imaging and laboratory follow-up.
Why it matters
Potential benefit: If successful, this could help clinicians identify patients at risk of adverse remodeling after STEMI so they can tailor follow-up and treatments earlier.
How similar studies have gone: Prior research using serial CMR and echocardiography combined with biomarkers has demonstrated the ability to predict adverse remodeling after STEMI, so this approach builds on established evidence.
