Active clinical trials for "Thromboembolism"

The primary objective of this study is to search for, in vitro, elements associated with IgG-dependent monocyte activation (signaling pathway activation, expression of pro-coagulant and pro-inflammatory factors) and to describe their prevalence in female patients with a history of proximal venous thromboembolism (proximal deep vein thrombosis or pulmonary embolism) compared to control women.

The purpose of this study is to determine retrospectively if the application of rivaroxaban after endovenous laser ablation with and without miniphlebectomy is safe and if it lowers the risk of venous thrombosis.

This study will utilize a retrospective cohort design. Using the Clinical Practice Research Datalink (CPRD) linked with Hospital Episode Statistics (HES) datasets, all patients with a record of VTE diagnosis between 1 April, 2008 and 31 March, 2013 will be identified and followed from the occurrence of VTE (index date) to the first of 24 months after the index date, end of the study period, leaving the database, or death.

Describe cardiovascular events in a cancer population receiving highly emetogenic chemotherapy (HEC) or moderately emetogenic chemotherapy (MEC).

Treatment of venous thromboembolism in cancer patients is specific and has been validated in trials that favor the use of LMWH (Low Molecular Weight Heparin) instead of VKA (Vitamin K Antagonist) treatment during 6 months. International recommendations have diffused this option.It is necessary to evaluate the compliance of physicians to this treatment by measuring the number of patients with cancer treated with long term use of LMWH.

Since decades, oral anticoagulation (OAC) with vitamin K antagonists (VKA) is an established therapy for both prevention and treatment of thromboembolism in daily clinical routine. Increasing life-expectancy, the demographic change and novel oral anticoagulants lead to an increasing complexity of medical therapy. However, data on quality and management of VKA therapy with phenprocoumon in current medical care are limited. Our aim was to investigate the quality of OAC with VKA in current health care and to evaluate the potential for improvements. The investigator-initiated thrombEVAL study program comprises two cohorts of patients treated with vitamin K antagonists for oral anticoagulation therapy in real-life settings: a multicentre cohort of patients in regular medical care and a multi-local, single centre cohort of patients in a telemedicine-based coagulation service. The study program is expected to enrol a total number of approximately 2,000 to 2,500 patients. Both cohorts build on a detailed clinical assessment of participants and anticoagulation therapy at study enrolment. Subsequently active and passive follow-up investigations are carried out to document and validate complications of the treatment. Primary short-term outcome is the distribution of time in therapeutic range; the primary long-term outcome comprises the composite of stroke, systemic embolism, myocardial infarction, major and clinically-relevant bleeding and death.

There are many different views regarding ideal duration and type of thromboprophylaxis after hip or knee surgery. An important factor in Fast-track surgery is early mobilization, which in itself is thought to prevent clotting. The investigators hypothesize that there is no increase with regards to thrombosis in patients receiving fast-track surgery with early mobilization and chemical thrombosis prophylaxis only during hospitalization.

The study is an open, single center, observational study at the Cardiology Dept at Uppsala University Hospital. The number of patients included will be 410. The objectives are to: Evaluate biomarkers and change of these related to myocardial infarction, during two years follow-up in an unselected patient population with a recent myocardial infarction. Evaluate if an early change of biomarkers can be related to death, new myocardial infarction, and ischemic stroke in the same population after two and five years follow-up.

The objective of this study is to characterize and compare the risks of long-term use of oral contraceptives containing drospirenone and of other established oral contraceptives.

Venous thromboembolism (VTE), which includes pulmonary embolism (PE) and deep vein thrombosis (DVT), is a common complication and leading cause of death in cancer patients. Large, population-based studies have shown that patients with cancer have four- to seven-fold increased risk of developing VTE compared with patients without cancer. VTE would be frequent in patients with advanced gastric cancer, especially associated chemotherapy. However, relatively few studies have been conducted regarding the incidence of VTE in Asian cancer patients. According to previous review, Asian patients significantly lower risk of developing VTE. The rate of VTE with advanced gastric cancer, and associated chemotherapy is not known in Asian patients. In addition, the impact of VTE on overall survival has not been documented in these patients.
