Cardiac CT imaging of coronary arteries and heart muscle after a heart attack
Official title: Multimodal Cardiac CT-Derived High-Risk Coronary and Myocardial Features for Predicting Adverse Outcomes After PCI in Patients With Acute Myocardial Infarction: A Multicenter Prospective Cohort Study
Run by Nanjing First Hospital, Nanjing Medical University · NCT07537296 · Data updated 2026-11-12
This will test whether adding a cardiac CT scan soon after PCI can help predict which adults who recently had a heart attack are at higher risk for later problems.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 or older who had a STEMI or NSTEMI within the past four weeks, were treated with PCI, are hemodynamically stable, and can undergo cardiac CT and telephone follow-up are ideal candidates.
✕Probably not a fit
Patients with eGFR <30 mL/min/1.73 m², iodine contrast allergy, prior CABG, prior MI or heart failure, severe arrhythmias, poor image quality, or expected survival under six months are unlikely to benefit or be eligible.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is an observational study of adults who had an acute myocardial infarction and underwent PCI; participants will receive a multimodal cardiac CT within seven days after PCI alongside routine echocardiographic follow-up and telephone monitoring. The protocol excludes patients with severe renal dysfunction, iodine contrast allergy, prior CABG, prior MI or heart failure, or other conditions that would prevent good imaging. Imaging and clinical follow-up data will be used to relate CT findings to subsequent remodeling and cardiovascular events. The goal is to develop better, more accessible risk-stratification tools after revascularization.
Why it matters
Potential benefit: If successful, the approach could improve prediction of adverse events after a heart attack and help tailor follow-up care to reduce complications.
How similar studies have gone: Echocardiography and cardiac MRI have established prognostic roles after AMI and small studies suggest cardiac CT may add prognostic information, but larger prospective validation is limited.
