Peripheral atherosclerosis is associated with the occurrence of restenosis after percutaneous coronary intervention
2007
The aim of our study was to evaluate, in patients with proven coronary artery disease (CAD) and treated with elective percutaneous coronary intervention (PCI), whether the coexistence of asymptomatic carotid and femoral atherosclerotic lesions would provide prognostic information in terms of occurrence of restenosis.We studied 104 patients with CAD (M/F=77/27), mean age 60.5+/-9 years. All patients were treated with elective PCI. After PCI the suspicion of restenosis was confirmed by coronary angiography. All patients underwent ultrasound duplex scan of carotid and femoral-popliteal-tibial axis to detect atherosclerotic lesions. According to ultrasound results, patients were classified as n…
Management strategies in patients affected by chronic total occlusions: results from the Italian Registry of Chronic Total Occlusions
2015
Background Through contemporary literature, the optimal strategy to manage coronary chronic total occlusions (CTOs) remains under debate. Objectives The aim of the Italian Registry of Chronic Total Occlusions (IRCTO) was to provide data on prevalence, characteristics, and outcome of CTO patients according to the management strategy. Methods The IRCTO is a prospective real world multicentre registry enrolling patients showing at least one CTO. Clinical and angiographic data were collected independently from the therapeutic strategy [optimal medical therapy (MT), percutaneous coronary intervention (PCI), or coronary artery bypass grafting (CABG)]; a comparative 1-year clinical followup was pe…
Five-Year Survival in Patients With ST-Segment–Elevation Myocardial Infarction According to Modalities of Reperfusion Therapy
2014
Background— Although primary percutaneous coronary intervention (pPCI) is the preferred reperfusion method for ST-segment–elevation myocardial infarction, it remains difficult to implement in many areas, and fibrinolytic therapy is still widely used. Methods and Results— We assessed 5-year mortality in patients with ST-segment–elevation myocardial infarction from the French Registry of Acute ST-Elevation or Non-ST Elevation Myocardial Infarction (FAST-MI) 2005 according to use and type of reperfusion therapy. Of 1492 patients with ST-segment–elevation myocardial infarction with a first call ≤12 hours from onset, 447 (30%) received fibrinolysis (66% prehospital; 97% with subsequent angiogra…
Mortality of patients with ST-segment elevation myocardial infarction and cardiogenic shock treated by PCI is correlated to the infarct-related arter…
2011
Background: Mortality of patients with ST-segment elevation myocardial infarction (STEMI) with cardiogenic shock (CS) on admission remains high despite invasive treatment. The aim of this analysis was to assess the relationship between the infarct-related artery (IRA) and the early and 12-month outcomes of patients with STEMI and CS treated by percutaneous coronary intervention (PCI). Methods: Two thousand ninety patients with STEMI and CS registered in the prospective Polish Registry of Acute Coronary Syndromes from October 2003 to November 2009 were included. Results: The in-hospital mortality in the left main (LM), left anterior descending artery (LAD), circumflex artery (Cx), and right …
Frailty and Mortality Outcomes After Percutaneous Coronary Intervention: A Systematic Review and Meta-Analysis.
2017
Abstract Background Frailty has been identified as a risk factor for mortality. However, whether frailty increases mortality risk in patients undergoing percutaneous coronary intervention (PCI) has been controversial. Therefore, we conducted a systematic review and meta-analysis of the frailty measures and mortality outcomes in this setting. Methods PubMed and EMBASE were searched until July 23, 2017 for studies evaluating the association between frailty measures and mortality in individuals who have undergone PCI. Results A total of 141 entries were retrieved from our search strategy. A total of 8 studies involving 2332 patients were included in the final meta-analysis (mean age: 69 years;…
Early endovascular aneurysm repair after percutaneous coronary interventions
2015
Objective The objective of this study was to report long-term results of early endovascular aortic aneurysm repair after percutaneous coronary intervention (PCI). Methods This was a retrospective analysis of all patients presenting with abdominal aortic aneurysm and coronary artery disease treated during the same hospitalization by endovascular aortic aneurysm repair performed soon after PCI. Primary outcomes were perioperative mortality, perioperative complications, survival after treatment, and freedom from reintervention. Results A total of 20 patients were included, and all completed both procedures. No deaths or abdominal aortic aneurysm ruptures occurred between the PCI and the aortic…
Long-term outcomes of percutaneous coronary interventions or coronary artery bypass grafting for left main coronary artery disease in octogenarians (…
2014
Percutaneous coronary intervention (PCI) with drug-eluting stents is an accepted alternative to surgery for the treatment of unprotected left main coronary artery (ULMCA) disease, but the long-term outcome in elderly patients is unclear. Aim of our study was to compare the clinical outcomes of octogenarians with ULMCA disease treated either with PCI with drug-eluting stents or coronary artery bypass grafting (CABG). The primary study end point was the composite of death, cerebrovascular accident, and myocardial infarction at follow-up. A total of 304 consecutive patients with ULMCA stenosis treated with PCI or CABG and aged 80 years were selected and analyzed in a large multinational regist…
Diagnostic Performance and Radiation Dose of the EOS System to Image Enchondromatosis: A Phantom Study
2020
Background: Radiation doses and capability of EOS, conventional radiography (CR), and computed tomography (CT) to detect and measure enchondromas in a dedicated five-year-old anthropomorphic phantom were compared. Methods: To simulate enchondromas, minced pieces of chicken bone and cartilage were packed in conventional kitchen plastic foil to create ovoidal/rounded masses and randomly hung on the phantom. The phantom was imaged five times with CR, CT, and EOS, each time changing the number and position of inserts. All images were reviewed by a senior radiologist and a radiology resident. Results: EOS and CR detected all inserts in 4/5 cases (80%), while in one case 1/17 inserts was not seen…
Efficacy of three methods for inserting calcium hydroxide-based paste in root canals
2017
BACKGROUND: To compare the quality of calcium hydroxide paste fillings performed by three different techniques. MATERIAL AND METHODS: Sixty extracted maxillary central incisors, with previous root canal treatment, were decoronated and the gutta-percha was completely removed from the root canals. Subsequently, the canals were filled with a calcium hydroxide-based paste composed of calcium hydroxide, bismuth carbonate, and glycerin. The study samples were divided into the following three groups on the basis of three insertion techniques (n = 20, each): conventional technique using a hand instrument (MAN), rotary Lentulo spiral (LEN) technique, and a combined technique combining conventional h…
Equivalences between refractive index and equilibrium water content of conventional and silicone hydrogel soft contact lenses from automated and manu…
2007
PURPOSE: The purpose of the present study was to develop mathematical relationships that allow obtaining equilibrium water content and refractive index of conventional and silicone hydrogel soft contact lenses from refractive index measures obtained with automated refractometry or equilibrium water content measures derived from manual refractometry, respectively. METHODS: Twelve HEMA-based hydrogels of different hydration and four siloxane-based polymers were assayed. A manual refractometer and a digital refractometer were used. Polynomial models obtained from the sucrose curves of equilibrium water content against refractive index and vice-versa were used either considering the whole range…
