Active clinical trials for "Thromboembolism"

The purpose of this quasi-experiment study, which could also be classified as a prospective observational intervention study, is to assess the impact of cytochrome P450 2C9 (CYP 2C9) and vitamin K epoxide reductase complex, subunit 1 (VKORC1) testing within a primary patient care setting.

VTE prophylaxis is not as routinely employed in medically ill patients as compared to surgical patients. This retrospective chart review project will evaluate the effectiveness of VTE prophylaxis in medically ill patients at the University of Utah Hospitals and Clinics compared to current literature. The study will ultimately serve as a quality improvement project to help improve patient care.

Cancer is a well known risk factor for venous thromboembolism (VTE) such as deep venous thrombosis (DVT) and pulmonary embolism (PE). Today we know that patients with adenocarcinomas of the gastro intestinal tract (GI-tract) often is in a hypercoagulable state. In our observational study we collect patients admitted to department with a tentative diagnosis of upper GI cancer including pancreas cancer and offer them flow doppler ultrasounds of both legs for diagnosis of DVT in the entire treatment time. The routine CT-scan of the chest is modified to diagnose PE. This will be compared with blood samples analysed for coagulation markers including D-dimer - a fibrinogen degradation product.

RATIONALE: Chemotherapy may cause blood clots to form in the thigh, leg, and lung. This study may help doctors understand how often blood clots occur in patients undergoing chemotherapy. PURPOSE: This clinical trial is studying how often blood clots occur in patients undergoing chemotherapy for solid tumors, including colorectal cancer, stomach cancer, lung cancer, ovarian cancer, pancreatic cancer, prostate cancer, or metastatic breast cancer

RATIONALE: Heparin or enoxaparin may be effective in preventing the formation of blood clots in patients with cancer who are undergoing surgery to remove the tumor. PURPOSE: Randomized clinical trial to compare the effectiveness of heparin with that of enoxaparin in patients who have cancer.

Main research question: What is the present venous thrombosis incidence and what are the current practices of prescribing thromboprophylaxis in patients with multiple myeloma (MM)? Design: The present study is a retrospective cohort study. The patients will be selected from the electronic patient dossier (EPD) of the University Medical Center Groningen (UMCG). The present study will include newly diagnosed adult patients with a first MM at the UMCG between 1st of January 2014 and 1st of September 2021. The primary outcome of the study is the incidence of venous thromboembolism (VTE) with one year of diagnosis of MM. The investigators will also describe the various thromboprophylaxis regimens used and their corresponding VTE incidence. The secondary outcome will be the incidence of arterial thrombosis (AT) within the same period of time. Possible confounders are the therapy administered for MM, thromboprophylaxis type, age and patient comorbidities. Lastly, the third outcome will be a description of current thromboprophylaxis practices in the UMCG. Each outcome will be described separately. Expected results: Based on the study by de Waal et al in which they included 474 MM patients treated at the UMCG and at 4 hospitals in the province Friesland, the investigators expect to record a VTE incidence of approximately 15%.

Retrospective monocentric registry to evaluate the efficacy and safety of different anticoagulants in patients with thromboembolic antiphospholipid syndrome

Patients with cancer hospitalized for an acute medical illness have an increased risk of venous thromboembolic events. Although international guidelines suggest the use of thromboprophylaxis in these patients, the recommendations are based on studies which included a percentage of patients with cancer without primarily focusing on this high risk group. Since patients with cancer present an increased risk of bleeding complications it is critical to evaluate the safety of thromboprophylaxis in the cancer group. Recent studies suggest a limited use of thromboprophylaxis in these patients. The aim of this study is to evaluate the use, efficacy and safety of thromboprophylaxis in medical cancer patients hospitalized for an acute medical disease. Design: observational, prospective study Primary end-point: incidence of major and clinically relevant non major bleeding during hospitalization Secondary endpoints: frequency of use, doses and contraindications for pharmacological thromboprophylaxis; venous thromboembolic events up to three months after discharge

The purpose of this study is to investigate the appropriate duration of dabigatran use after radiofrequency catheter ablation for paroxysmal atrial fibrillation in patients with low thromboembolic risk. According to the most recent guideline, anticoagulation is recommended to continue at least 2 months after the procedure. However bleeding risk with anticoagulant is also problematic. Post-procedural thrombosis is considered due to acute inflammation or char formation at the site of ablation, and these reaction occurs mostly within 1 month after the procedure. Also, the risk of thromboembolism is low in patients with CHA2DS2-VASc score less than 1. The investigators hypothesized that dabigatran use for the first 1 month after the RFCA for patients with paroxysmal AF and low thromboembolic risk would be sufficient for efficacy and safety compared to conventional dabigatran use for 2 months.

Following the findings of the clinical trials in drug development, this global non-interventional cohort field study will investigate rivaroxaban under clinical practice conditions in comparison with current standard of care for patients with acute deep vein thrombosis (DVT). The main goal is to analyze long-term safety in the use of rivaroxaban in the treatment of acute DVT in routine clinical practice.
