The Metabolic Syndrome as a Prohypertensive State
2008
describe the ability of MetS to pre-dict the development of hypertension. The conclusions of this interesting study (CRISPS2) support the concept that the MetS, regardless of the criteria used to define it (NCEP-ATPIII or IDF), may be considered, at least in part, as a potentially reversible prohypertensive state.
D-dimer testing: advantages and limitations in emergency medicine for managing acute venous thromboembolism
2007
Patients with suspected deep vein thrombosis (DVT) or pulmonary embolism (PE) are frequently admitted to an Emergency Department (ED) for initial evaluation. However, management of patients with suspicion of acute venous thromboembolism (VTE) in this clinical setting can be difficult; in fact symptoms and signs of DVT are non-specific and can be found in a broad spectrum of non-thrombotic disorders. An accurate and timely objective diagnosis is necessary for immediate and correct identification of patients with acute VTE, while avoiding the bleeding risk associated with unnecessary anticoagulant therapy in patients where DVT or PE have been ruled out. The diagnostic approach to patients wit…
Influence of the terminal complement-complex on reperfusion injury, no-reflow and arrhythmias: a comparison between C6-competent and C6-deficient rab…
1996
Objective: The complement system has been suggested to play a role in reperfusion injury which may result from an enhanced destruction of myocardial tissue or from an impairment of reflow. We investigated the influence of the C5b-9 complement complex on infarct size, reflow and arrhythmogenesis. Methods: Twenty-eight C6-competent rabbits and 18 rabbits with congenital C6 deficiency were subjected to either 30 min or 2 h of coronary artery occlusion followed by reperfusion. C6 deficiency was confirmed by the complement titration test and immunohistology. The triphenyl tetrazolium chloride method was used to delineate infarct size. Reflow into infarcted areas was evaluated histologically afte…
Coronary stent implantation in acute vessel closure 48 hours after an unsatisfactory coronary angioplasty
1990
We report the implantation of a balloon-expandable stent in a patient with acute vessel closure in the state of evolving myocardial infarction following 48 hr after unsatisfactory coronary angioplasty. The stent was implanted after successful recanalization of an occluded left anterior descending artery, with repeated unsatisfactory results of balloon angioplasty. Adjunct thrombolytic therapy was contraindicated. No residual stenosis was documented in immediate control angiograms, or after 24 hr, 3 weeks, and 4 months.
Nonroutine Use of Intra-Aortic Balloon Pump in Cardiogenic Shock Complicating Myocardial Infarction With Successful and Unsuccessful Primary Percutan…
2018
Abstract Objectives The authors sought to compare outcomes of patients with myocardial infarction and cardiogenic shock (CS) treated with percutaneous coronary intervention (PCI) with or without intra-aortic balloon pump (IABP) support according to final epicardial flow in the infarct-related artery. Background A routine use of IABP is contraindicated in patients with myocardial infarction and CS. There are no data regarding the subpopulation of patients who may benefit from such support besides patients with mechanical complications of myocardial infarction. Methods Prospective nationwide registry data of patients with myocardial infarction and CS treated with PCI between 2003 and 2014 wer…
Efficient 3D Deep Learning for Myocardial Diseases Segmentation
2021
Automated myocardial segmentation from late gadolinium enhancement magnetic resonance images (LGE-MRI) is a critical step in the diagnosis of cardiac pathologies such as ischemia and myocardial infarction. This paper proposes a deep learning framework for improved myocardial diseases segmentation. In the first step, we build an encoder-decoder segmentation network that generates myocardium and cavity segmentations from the whole volume, followed by a 3D U-Net based on Shape prior to identifying myocardial infarction and myocardium ventricular obstruction (MVO) segmentations from the encoder-decoder prediction. The proposed network achieves good segmentation performance, as computed by avera…
Suppression of Electrographic Seizures Is Associated with Amelioration of QTc Interval Prolongation in Patients with Traumatic Brain Injury.
2021
Introduction: Disorders in electroencephalography (EEG) are commonly noted in patients with traumatic brain injury (TBI) and may be associated with electrocardiographic disturbances. Electrographic seizures (ESz) are the most common features in these patients. This study aimed to explore the relationship between ESz and possible changes in QTc interval and spatial QRS-T angle both during ESz and after ESz resolution. Methods: Adult patients with TBI were studied. Surface 12-lead ECGs were recorded using a Cardiax device during ESz events and 15 min after their effective suppression using barbiturate infusion. The ESz events were diagnosed using Masimo Root or bispectral index (BIS) devices.…
Diagnosis and definition of biventricular non-compaction associated to Ebstein's anomaly
2011
Abstract Background Non-compaction of ventricular myocardium is a rare congenital cardiomyopathy characterized by the presence of an extremely thickened endocardial layer with prominent trabeculations and deep recesses in communication with ventricular chamber and determining the typical spongeous aspect. The diagnosis of non-compaction of ventricular myocardium is possible through the identification of morphological alterations by echocardiographic evaluation. Ebstein's anomaly is a rare congenital cardiac disease, defined as the significant apical displacement of the part of the tricuspid valve causing significant tricuspid regurgitation and reduction of the functional right ventricle, ri…
0200: Predictors of angiographically visible distal embolization in ST elevation myocardial infarction patients treated by primary percutaneous coron…
2016
Aspiration thrombectomy during primary percutaneous coronary intervention (p-PCI) in ST elevation myocardial infarction (STEMI) has been proposed to restore myocardial reperfusion. But important controversies remain concerning the usefulness of thrombectomy to improve this perfusion. Our objective was to evaluate the impact of manual thrombectomy on the occur-rence of angiographically visible distal embolization (AVDE) during p-PCI in STEMI. 346 consecutive patients admitted for STEMI who underwent p-PCI and thrombectomy were included. Clinical, angiographic and therapeutics characteristics were assessed. AVDE was defined as an abrupt vessel closure occurring at any point during the PCI pro…
Coronary Angioplasty in Unstable Angina
1990
When Gruntzig introduced the revolutionary method of percutaneous transluminal coronary angioplasty (PTCA) for the treatment of coronary artery stenoses, he initially devoted this technique only to patients with stable angina pectoris [8]. Very soon, however, it was discovered simultaneously by Williams et al. [19] and by our group [12] that this method can also be used in patients with unstable angina pectoris. The earliest experiences with PTCA in 1980 were published by our two groups (Table 1). In these series the average degree of stenosis was somewhat lower than that today, while the residual stenosis after treatment was slightly higher. The very rough balloons and guiding catheters av…
