Conditions
Summary
Ischemic heart disease (IHD) remains a leading cause of morbidity and mortality worldwide. Accurate risk stratification is essential for guiding clinical management and improving long-term outcomes in patients with ischemic myocardial injury. Cardiovascular magnetic resonance (CMR) imaging provides comprehensive assessment of myocardial structure, function, and tissue characteristics, enabling detailed evaluation of ischemic injury and its consequences. This multicenter, retrospective observational study aims to investigate the prognostic value of multiparametric CMR-derived imaging markers in patients with ischemic heart disease who underwent clinically indicated CMR examinations. Imaging parameters of interest include late gadolinium enhancement (LGE), infarct size, microvascular obstruction (MVO), left ventricular and left atrial strain, and native T1 and T2 mapping values. Long-term clinical outcomes will be obtained from existing medical records. The primary outcome is major adverse cardiovascular and cerebrovascular events (MACCE), and secondary outcome is cardiovascular death. This study seeks to clarify the role of CMR in long-term risk stratification of patients with ischemic heart disease.
Eligibility
Inclusion Criteria4
- Adults (≥18 years of age).
- Patients with ischemic heart disease, including prior or recent myocardial infarction, who underwent clinically indicated cardiac magnetic resonance (CMR) imaging.
- Availability of analyzable CMR images, including but not limited to cine imaging, late gadolinium enhancement (LGE), and parametric mapping sequences (T1 and/or T2 mapping), as applicable.
- Availability of baseline clinical data and longitudinal follow-up information.
Exclusion Criteria3
- Poor image quality or incomplete CMR data precluding quantitative analysis.
- Presence of other severe comorbid conditions expected to significantly affect survival or clinical outcomes.
- Missing key clinical outcome data during follow-up.
