Revacept, an Inhibitor of Platelet Adhesion in Symptomatic Carotid Artery Stenosis: Design and Rationale of a Randomized Phase II Clinical Trial
2020
AbstractPatients with stroke or transient ischemic attacks (TIAs) and internal carotid artery stenosis harbor an increased risk of recurrent stroke especially within 2 weeks after the first event. In addition, the revascularization procedure itself (carotid endarterectomy [CEA] or carotid artery stenting [CAS]) is associated with both clinically apparent and silent brain infarctions, mainly caused by the embolic nature of the ruptured carotid plaque. The glycoprotein VI (GPVI) fusion protein Revacept is a highly specific antithrombotic drug without direct inhibition of systemic platelet function that might reduce periprocedural distal embolization from the vulnerable ruptured plaque located…
Clinical Characteristics, Treatments, and Outcomes of Patients with Myocardial Infarction with Non-Obstructive Coronary Arteries (MINOCA): Results fr…
2020
Background: Diagnosis of myocardial infarction with non-obstructive coronary arteries (MINOCA) requires both clinical evidence of acute myocardial infarction (AMI) and demonstration of non-obstructive coronary arteries using angiography. We compared the clinical features, treatments, and three-year outcomes in patients with MINOCA and myocardial infarction with obstructive coronary artery disease (MI-CAD). Methods: We retrospectively analyzed data for 205,606 hospitalized patients with AMI. MINOCA was indicated as a working diagnosis in 6063 patients (2.94% of all AMI patients). For the control group we included 160,886 patients with MI-CAD. We evaluated the baseline characteristics, medica…
The Multifaceted Interplay between Atrial Fibrillation and Myocardial Infarction: A Review
2021
International audience; This review was conducted to emphasize the complex interplay between atrial fibrillation (AF) and myocardial infraction (MI). In type 1 (T1) MI, AF is frequent and associated with excess mortality. Moreover, AF after hospital discharge for T1MI is not rare, suggesting the need to improve AF screening and to develop therapeutic strategies for AF recurrence. Additionally, AF is a common trigger for type 2 MI (T2MI), and recent data have shown that tachyarrhythmia or bradyarrhythmia could be a causal factor in, respectively, 13–47% or 2–7% of T2MI. In addition, AF is involved in T2MI pathogenesis as a result of severe anemia related to anticoagulants. AF is also an unde…
Personality and Defence Mechanisms in Takotsubo Cardiomyopathy
2017
IntroductionTakotsubo cardiomyopathy (TC) is an acute cardiologic syndrome, characterized by specific symptoms and ECG, echocardiographic and enzymatic abnormalities, similar to an acute myocardial infarction, with no hemodynamically significant stenosis at coronary-ventriculography.ObjectiveTo assess personality in TC patients in order to find common psychopathological elements.MethodsA series of consecutive patients suffering from TC hospitalized at the Cardiology Unit of “Ingrassia” Hospital in Palermo in 2013–2014, were included in the study. We used Structured Clinical Interview for Axis I and II, according to DSM-IV TR criteria. Further, the Defense Mechanisms Inventory (DMI), used in…
Basics of Image Interpretation in Interventional Neuroradiology
2011
The majority of patients with cerebral vascular diseases, demanding neuroradiological interventions are those, who present with potential life-threatening spontaneous intracranial/intracerebral haemorrhages due to cerebral aneurysms or/and arteriovenous malformations (AVMs) or with cerebral infarction due to intra-arterial thrombi in cerebral arteries. Neuroradiological procedures (interventional neuroradiology) (IN), always, performed in general anaesthesia can be divided into occluding and opening interventions.
An FFR CT diagnostic strategy versus usual care in patients with suspected coronary artery disease planned for invasive coronary angiography at Germa…
2017
Aim Diagnostic evaluation practices for suspected coronary artery disease (CAD) may vary between countries. Our objective was to compare a CT-derived fractional flow reserve (FFRCT) diagnostic strategy with usual care in patients with planned invasive coronary angiography (ICA) enrolled in the PLATFORM (Prospective Longitudinal Trial of FFRCT: Outcome and Resource Impacts) study at German sites. Methods Patients were divided into two consecutive observational cohorts, receiving either usual care or CT angiography (CTA)/FFRCT. The primary endpoint was the percentage of patients planned for ICA, with no obstructive CAD on ICA within 90 days. Secondary endpoints included death, myocardial infa…
P729PD-1/PD-L1 axis contributes to infarct size in ST elevation myocardial infarction
2014
Programmed death-1 (PD-1) and Programmed death-1 ligand (PD-L1) regulate immune response. Previous studies associate an immune deregulation in ST-elevation myocardial infarction STEMI. We recruited 100 patients with a first STEMI treated with reperfusion. In all patients PD-1 and PD-L1 expression was studied 24 h post-reperfusion in peripheral blood mononuclear cells (PBMCs), by means of flow cytometry and molecular biology. PD-1 and PD-L1 expression was serially analyzed in the first 20 patients before reperfusion and 24h, 96h and 30 days afterwards. Results were compared with 30 age- and sex-matched controls. Cardiac Magnetic Resonance was used to quantify infarct size 1-week after infarc…
Mechanical recanalization in basilar artery occlusion: The ENDOSTROKE study
2015
Objective A study was undertaken to evaluate clinical and procedural factors associated with outcome and recanalization in endovascular stroke treatment (EVT) of basilar artery (BA) occlusion. Methods ENDOSTROKE is an investigator-initiated multicenter registry for patients undergoing EVT. This analysis includes 148 consecutive patients with BA occlusion, with 59% having received intravenous thrombolysis prior to EVT. Recanalization (defined as Thrombolysis in Cerebral Infarction [TICI] score 2b–3) and collateral status (using the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology collateral grading system) were assessed by a blinded core l…
Cerebrovascular Brainstem Diseases with Isolated Cranial Nerve Palsies
2002
There is a significant number of individual patients with cranial nerve palsies as the sole manifestation of MRI- and, less frequently, CT-documented small brainstem infarctions or hemorrhages. The 3rd and 6th nerves are most commonly involved and, less frequently, the 4th, 5th, 7th, and 8th nerves. An intra-axial basis for such lesions may be underestimated if the diagnosis is based solely on MRI. The electrophysiologic abnormalities indicating brainstem lesions may be independent of MRI-documented morphological lesions. This paper reviews the literature on cerebrovascular brainstem diseases manifesting as isolated cranial nerve palsies. It supports the concept that small pontine and mesen…
Hypoxic burden and angiogenic factors in patients with myocardial infarction and obstructive sleep apnea
2019
Introduction: The amount and severity of hypoxia have been related to risk of cardiovascular events. Aim: To determine the relationship between nocturnal hypoxic burden and pro- angiogenic factors in patients with obstructive sleep apnea (OSA) and myocardial infarction (MI). Method: A prospective, observational study in patients with a first acute MI. Eligible patients underwent a polysomnography within 30 days after MI, and a serum blood sample was drawn in order to measure a panel of angiogenic factors by Luminex technology. A hypoxic burden index (HBI) was calculated as the integral area under the desaturation curve (obtained by calculating the integral of the oxygen saturation reduction…
