AIMS To assess the short- and long-term effects of postconditioning (p-cond) on infarct size, extent of myocardial salvage, and left ventricular ejection fraction (LVEF) in a series of patients presenting with evolving ST-elevation myocardial infarction (STEMI). Previous studies have shown that p-cond during primary percutaneous coronary intervention (PCI)… (More)
Angiotensin-converting enzyme 2 (ACE2) cleaves Angiotensin-II to Angiotensin-(1-7), a cardioprotective peptide. Serum soluble ACE2 (sACE2) activity is raised in chronic heart failure, suggesting a compensatory role in left ventricular dysfunction. Our aim was to study the relationship between sACE2 activity, infarct size, left ventricular systolic function… (More)
UNLABELLED Myocardial fibrosis is always present in end-stage heart failure and is a major independent predictor of adverse cardiac outcome. Cardiac magnetic resonance (CMR) is an imaging method that permits a non-invasive assessment of the heart and has been established as the "gold standard" for the evaluation of cardiac anatomy and function, as well as… (More)
OBJECTIVES To describe the imaging features of the central airway pathology, correlating the findings with those in pathology and virtual endoscopy. To propose a schematic and practical approach to reach diagnoses, placing strong emphasis on multidetector computed tomography (MDCT) findings. METHODS We reviewed our thoracic pathology database and the… (More)
BACKGROUND Chronic total occlusion percutaneous coronary intervention (CTO-PCI) can improve angina and left ventricular ejection fraction (LVEF). These benefits were not assessed in populations with heart failure with reduced ejection fraction (HFrEF). We studied the effect of CTO-PCI on left ventricular function and clinical parameters in patients with… (More)
Objective To identify significant predictors of the presence and extent of microvascular obstruction in the acute phase of STEMI patients.
Shortening symptom-to-reperfusion time improves prognosis in patients with ST-segment elevation myocardial infarction. Accordingly, current guidelines target a door-to-balloon time <90 minutes, irrespective of symptom-to-door time; nevertheless, the relation between door-to-balloon and symptom-to-door time and its potential impact on myocardial salvage… (More)
