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.
iLVSD (ischemic left ventricular dysfunction) is a leading cause of heart failure (HF) and death. It is widely treated via coronary revascularization despite limited understanding of determinants of revascularization response. "Viability" imaging (to differentiate infarcted from salvageable myocardium) has been widely touted as an effective means to predict revascularization response. However prior multicenter trials have derived negative conclusions using heterogenous data with respect to both image modality and analysis. Data by our investigators and others indicate that infarct transmural…
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. Prognostically important CAD: either multivessel CAD (triple vessel or double vessel CAD including left anterior descendant artery (LAD), significant coronary stenosis defined as ≥ 70% based on coronary angiography, fractional flow reserve (FFR) ≤ 0.80 or instantaneous wave-free ratio (iFR) ≤ 0.89) or left main disease (+/- other CAD) for which significant stenosis defined as \> 50% based on coronary angiography,…
Cardiac MRI, also known as cardiac magnetic resonance imaging, is a non-invasive imaging technique that uses strong magnetic fields and radio waves to produce detailed pictures of the heart and its surrounding structures
