Study on the Clinical Course Of Pulmonary Embolism

Cardiovascular DiseasesVenous Thromboembolism1 more

The course of both pulmonary embolism (PE) and one of its more relevant late complications, i.e. chronic thromboembolic pulmonary hypertension (CTEPH) is still substantially unknown. Recent evidence has shown that the incidence of CTEPH is higher than previously believed, but this has not been confirmed by other studies. A clear link between PE and CTEPH has been questioned by some experts. A great number of patients affected by PE persistently have residual chronic thromboembolic material the meaning of which is a matter of debate. The evidence sustaining a link between chronic residual PE and subsequent PE recurrences or CTEPH is insufficient. Thus, a nationwide, multicentre, prospective cohort study was designed with the following aims: to ascertain the incidence of symptomatic CTEPH after a first episode of acute PE; to ascertain the incidence of venous thromboembolic (VTE) recurrences after a first episode of acute PE; to evaluate whether a relation exists between chronic residual PE and CTEPH to evaluate whether a relation exists between chronic residual PE and VTE recurrences; to evaluate whether a relation exists between persistent right ventricular dysfunction and CTEPH; to evaluate whether a relation exists between persistent right ventricular dysfunction and PE recurrences. For each enrolling centre, consecutive outpatients or inpatients with an objectively diagnosed first acute PE episode are considered eligible.

Free DNA and Nucleosome Concentrations in Pathological Pregnancies

PregnancyVenous Thrombosis8 more

The primary objective of this study is to demonstrate that plasma concentrations of nucleosomes and free DNA differ between three groups: pregnant patients with complications typical of placental insufficiency or venous thrombosis (group P), healthy women (Group T1) and healthy pregnant women (Group T2).

Apixaban in the Prevention of Stroke and Systemic Embolism in Patients With Atrial Fibrillation...

Anticoagulation

The present study will be conducted to assess the following research questions in real-life conditions in France: What are the patient and disease characteristics, comorbidities and treatment history in NVAF patients initiating a new Anticoagulant (AC) treatment, according to treatment currently available and prescribed (apixaban, other NOACs, VKAs), and are the AC-naive patient profiles different from one treatment pattern to another when initiating a new AC treatment? What are the HCP's reasons for discontinuing the previous AC strategy for initiating and choosing the newly initiated AC treatment in NVAF patients? What are the conditions of newly-initiated apixaban prescriptions in NVAF patients: prescriber, proportion of naïve/experienced patients, daily dosage and number of daily doses?

Many drug interactions with Warfarin are well documented in the literature, including interactions with a variety of antibiotics. However,in mamy cases it is difficult to predict when the interaction remains theoretical and when it becomes clinically significant and will be reflected in the individual patient. This study's aim is to identify and characterize related conditions (including comorbidities, laboratory test results and other parameters related to the patient)that might be predictors for drug interactions turning from theoretical to clinically significant.

Prognostic Factors for Acute Pulmonary Embolism in Critically Ill Patients

Acute Pulmonary Embolism (PE)

Acute pulmonary embolism (PE) is an important cause of in-hospital mortality and may be rapidly fatal if not diagnosed and treated. Despite recent advances in diagnostic and therapeutic modalities, it is still one of the important causes of hospital mortality. Previous several reports have described the variable outcome of patients with PE with reported mortality rate ranging from 8.1% (stable patients) to 25% (with cardiogenic shock) and 65% (post cardiopulmonary resuscitation). Nevertheless, there are no published studies from Korean hospitals that assessed the outcome of acute PE treated in the hospital with IV unfractionated heparin. We conducted this study to determine the outcome, risk factors, clinical characteristics and demographics of patients with acute PE and to identify possible demographic and clinical factors associated with prognosis.

Clinical Predictors for Venous Thromboembolism in Patients With a History of Thrombosis (PREDICTORS)...

Thromboembolic Disease RecurrentDeep Vein Thrombosis3 more

Patients with a history of blood clots are at risk of developing additional clots in the future. Doctors use a tool called a clinical decision rule to tell them how likely it is that a patient has a blood clot and if they should have further testing to look for the clot. This tool may cause doctors to over-diagnosis a recurrent clot because the symptoms may be left over from the previous clot. Correctly diagnosing a recurrent blood clot is very important since there are risks associated with both over-diagnosis and under-diagnosis. If a recurrent blood clot is missed (under-diagnosis) the patient is at risk of death from a clot in the lungs. If blood thinners are prescribed when they are not needed (over-diagnosis), the patient may have to take blood thinners for their lifetime and risk having serious bleeding.

Prevalence of Pulmonary Embolism in ICU

Pulmonary EmbolismDeep Venous Thrombosis

The primary objective of this study was to estimate the prevalence of PE among consecutive ICU patients receiving MV who required thoracic computed tomography (CT) with contrast agent injection, regardless of whether PE was suspected clinically. The secondary objectives were to assess the association between PE and DVT, to identify risk factors for VTE, and to determine the outcome of VTE.

Pulmonary EmbolismAtrial Fibrillation1 more

This is a multi-center study designed to evaluate the accuracy and precision of the INRatio® Prothrombin Time (PT) Monitoring System, utilizing the INRatio test strip newly designed for low sample volume and heparin insensitivity, when used by trained medical professionals for the quantitative determination of PT and International Normalized Ratio (INR) in fingerstick and venous whole blood from subjects on oral anticoagulation therapy (OAT). These results will be compared to those PT/INR results obtained on plasma from the same subjects as analyzed at a central laboratory with the Sysmex CA-560 System.
