Exclusion of ischemia is important in patients with newly diagnosed systolic heart failure (HF). We prospectively compared standard-of-care invasive catheter angiography (iCA) and echocardiography to a novel non-invasive strategy of both Coronary Computed Tomographic Angiography (CCTA) and Cardiovascular MRI (CMR) to determine the etiology of...

Assessment of myocardial "blush" by either Myocardial Blush Grade or TIMI Myocardial Perfusion Grade, is the angiographic method currently preferred to confirm myocardial tissue-level perfusion after primary percutaneous intervention. This review focuses on the utility of angiographic "blush" as a simple, widely available, and virtually...

Aims: To assess the main predictors and significance of filter no-reflow (FNR) in protected saphenous vein graft (SVG) percutaneous coronary intervention (PCI) and the effect of two different filter-based devices on FNR incidence. The phenomenon of FNR has been described as a transient impairment of blood flow due to debris plugging of a...

Background: In ST-elevation myocardial infarction (STEMI) patients, the main stimuli involved in endothelial progenitor cells (EPCs) mobilization are not fully understood. We aimed to assess by cardiac magnetic resonance (CMR) whether the extent of ischemic myocardium (area at risk (AAR)) or of necrotic myocardium (infarct size (IS)) can be...

Background After ST-elevation myocardial infarction (STEMI), microvascular obstruction (MVO) can be assessed using semiquantitative angiographic "blush" scores subject to interoperator variability. Quantitative Blush Evaluator (QuBE) is a free computer-calculated algorithm that evaluates myocardial blush on a continuous scale with improved...
