Filter by:In patients with suspected APE (Acute Pulmonary Embolism) referred to the intensive care unit (ICU)after major surgery, serum NT-proBNP (N-terminal proBNP), Troponin-I and D-dimers were measured according to the standard hospital protocol. To definitively confirm or exclude APE, all patients underwent an angiographic CT-scan of the thorax.
The use of prophylaxis for venous thromboembolism (VTE) remains grossly underused for women who undergo gynecologic surgery for benign conditions world wide and especially in developing countries including our region. Having a research in our locality for the first time might raise awareness of the importance of VTE prophylaxis.
Epidemiological studies have shown a 2-3 fold increased long-term risk of arterial cardiovascular disease after venous thrombosis, most predominant in the first year following initial venous thrombosis. The results of recent observational studies that showed 40-50% risk reductions for first venous thrombosis occurrence when using a statin are in this aspect promising. The results are also somewhat surprising, because the mechanism behind this effect is unclear. Dyslipidemia may be the most plausible explanation to be considered. However, as dyslipidemia is not related to an increased risk of venous thrombosis, it is unlikely that statins decrease venous thrombosis risk by lipid lowering activities. Recent observations indicate that coagulation can activate the initial formation of atherosclerosis. Our hypothesis is therefore that the coagulation profile in persons with venous thrombosis is improved when using a statin, ultimately leading to less atherosclerosis: another well known property of statin use.
RAZIONALE Pulmonary embolism is a complex disease, with a highly variable clincal presentation. Diagnosis starts with clinical probability assessment mainly based on medical history and rapidly available clinical data. Pulmonary embolism can be managed by emergency department, cardiology, pneumology geriatrics or internal medicine physicians. Thus, initial clinical management can varies based on the attitude of the attending physician. Diagnosis is a crucial point as it can influence short term mortality. OBJECTIVE The registry has 3 main objectives: 1. educational objective, 2. improvement in the knowledge of epidemiology, management and outcome of acute pulmonary embolism in Italy 3. scientific objective
The presence of clots in the veins of arms and/or legs or lungs of Cancer patients decreases their quality of life, delays their treatment and may cause death. The best way to avoid new clots is by giving blood thinners before clots are formed, but even some patients who are taking blood thinners may form blood clots. A major problem is that it is difficult to know which patients form clots while they are receiving blood thinners, a situation called treatment failure. Several studies have shown that by doing blood tests that measure the formation of clots, the investigators could know if the patient is responding to the blood thinners. If this is proven, the investigators will be able to apply these tests to all patients.
Obstructive sleep apnea (OSA) is a clinical syndrome characterized by repetitive closure of the airway and frequent awakenings during sleep. Repeated episodes of hypoxia, decrease in intrathoracic pressure, increased venous return and venous stasis, damage to vascular wall may ensue. An increased tendency for coagulation has also been reported in OSA. Venous stasis, vascular endothelial activation and hypercoagulability are also known risk factors for thromboembolism. All of these pathophysiologic changes in OSA may predispose patients for the development of pulmonary embolism (PE) however there is limited data about role of thromboembolic events in OSA.
The study aims to document the flow of German patients with cancer and acute deep vein thrombosis from first visit to diagnosis and treatment, the applied diagnostic procedures, and therapy modalities.
Currently, guidelines and clinical practice differ considerably with respect to use of anticoagulant treatment during cast immobilization of the lower leg. Trials that have been carried out were aimed at efficacy only, had small sample sizes and therefore mainly used asymptomatic thrombosis as endpoint. From these trials an overall risk benefit-balance could not be established, hence the current controversy. In the proposed study the investigators will use relevant symptomatic endpoints in a large cohort of patients. Furthermore the investigators will follow subjects with an adverse event for a longer period, during which the investigators will assess the long term sequelae of these events. Lastly, the investigators will determine high risk groups that will benefit most from anticoagulant treatment. Objective: Comparative effectiveness research to determine cost-effectiveness of two existing policies, i.e. treatment with low molecular weight heparin (LMWH) during lower leg plaster cast immobilization following surgical or conservative treatment. In addition the investigators will investigate personalized prophylaxis based on genetic and acquired risk factors.

Occurrence of venous thromboembolism during in Vitro Fertilization (IVF) pregnancies has been reported in numerous case reports and in two small consecutive series. The incidence of venous thromboembolism (VTE) after IVF has been claimed to be comparable to the incidence of VTE during normal pregnancy. No information exists concerning pulmonary embolism (PE). The aim is to estimate and compare the risk of both PE and VTE during the the different phases of pregnancy after IVF to that in age and period matched control women. The investigators will use the Swedish National Health Registers to estimate the risk.
