Filter by:This is a cross-sectional study of post myocardial infarction patients which is designed to determine the prevalence of left ventricular thrombi (blood clots) using non-contrast echocardiography and to compare this with the prevalence of left ventricular thrombi using contrast echocardiography. Secondary aims of this study are (1) to identify clinical and imaging correlates of left ventricular thrombi, and (2) to compare quantitative measurements of left ventricular chamber size, function, and myocardial mass using contrast and non-contrast echocardiography.
The purpose of this Clinical Evaluation is the continued assessment of the XIENCE Everolimus Eluting Coronary Stent System (XIENCE V® and XIENCE PRIME™ EECSS) with the primary focus on clinical outcomes in the treatment of female patients with de novo coronary artery lesions, and the characterization of the female population undergoing stent implantation with a XIENCE stent.
This study is being conducted to evaluate an investigational instrument called the HEM-AVERT Perianal Stabilizer and its efficacy in reducing the occurrence or severity of hemorrhoids and thrombosed external hemorrhoids (TEH) which commonly occur during vaginal delivery.
To collect postmarketing data about Fragmin safety and efficacy in the treatment of deep vein thrombosis with or without pulmonary embolism in cancer patients.
There are no established guidelines regarding interruption of warfarin anticoagulant therapy prior to surgical implantation of cardiac pacemakers. Continuing the anticoagulant could potentially result in increased bleeding complications from the implantation surgery, whereas discontinuing the anticoagulant could predispose the patient to blood clots and strokes. In this study we intend to randomly assign warfarin-treated patients either into interrupted or continued warfarin therapy prior to pacemaker implantation with the purpose of establishing the rate of complication in these groups. Our hypothesis is that a cardiac pacing device can be safely implanted without discontinuation of the anticoagulant therapy.
Migraine was described as related to stroke in adults and children as well. Complete thrombophilic status was not study in large groups of pediatric patients. The purpose of our study is to assess the prethrombotic profile among children and teenagers diagnosed as suffering from migraine attacks.
The purpose of this study is to assess efficacy and safety of optional vena cava filter implanted 3 months in prevention of recurrent pulmonary embolism in patients presenting with acute pulmonary embolism associated with thrombotic risk factors
The purpose of this study is to learn if apixaban can prevent blood clots in the leg (deep vein thrombosis [DVT]) and lung (pulmonary embolism [PE]) that sometimes occur within patients hospitalized for acute medical illness, and to learn how apixaban compares to enoxaparin (Lovenox®) for preventing these clots. The safety of apixaban will also be studied.
More than 5 years ago the DVT FREE Registry was conceived. Its database consists of 5,451 ultrasound-confirmed DVT patients from 183 institutions. This database is rich in information of critical importance to health care providers. The information contained within the database will be revisited to provide more detailed analyses which will be used for risk factor assessment and for decision-making regarding the implementation of VTE Prophylaxis.
The purpose of this study is to learn whether apixaban prevents the development of blood clots in the leg (deep vein thrombosis) and lung (pulmonary embolism), which sometimes occur after knee replacement surgery, and to compare the efficacy of apixaban with that of enoxaparin (Lovenox®) in the prevention of these clots. The safety of apixaban will also be studied.
