STICH3C Cardiac Magnetic Resonance Observational Study
Trial Parameters
Brief Summary
STICOS will test the hypothesis that residual jeopardized myocardium, late gadolinium enhancement, and non-ischemic substrate after revascularization is associated with postoperative adverse cardiovascular events such as heart failure , readmission, or death. This study will look at whether certain heart tissue abnormalities seen on MRI scans can help predict serious health problems after heart procedures like stents or bypass surgery.
Eligibility Criteria
Inclusion Criteria: 1. Men and women ≥ 18 years old 2. LVEF ≤ 40% (quantified by echo, single-photon emission computed tomography \[SPECT\], or CMR within 2 months of enrollment) 3.
