Embolism in COVID-19 Positive Patients

COVID-19 PneumoniaEmbolism1 more

Covid-19 outbreak has caused death of millions of people because of not only the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection itself but also infection dependent complications. Abnormalities in thrombotic events leads to some of these complications which eventually result in emboli. The endothelial damage caused by the virus interacting with ACE2 on the host cells leads to the activation of coagulation cascade. Accumulation of byproducts of the cascade might have some roles in embolism inducing risk of organ damage, other life-threatening problems, and even death. To enlighten the factors triggering embolism, the investigators have focused on genetic changes such as polymorphisms and mutations in certain genes in DNA samples coming from intensive care unit (ICU) patients.

Cerebral Microembolism in the Critically Ill With Acute Kidney Injury

Cerebral Embolism

The primary objective of this study is to investigate the impact of continuous renal replacement therapy and intermittent renal replacement therapy on microbubble / cerebral microemboli generation in a cohort of critically ill patients with dialysis-dependent acute kidney injury.

Study to Develop a Reliable Nomogram That Incorporates Clinical and Genetic Information

Pulmonary EmbolismDeep Vein Thrombosis1 more

In this research study, the investigators are trying to find a better way to set the dose of a common blood-thinning medication. Patients with blood clots or a risk of blood clots (or stroke) sometimes have to take an approved medication called warfarin. Warfarin is a commonly prescribed, approved blood thinning medicine taken by mouth. There is a certain level of warfarin that is best for each patient at a particular time. It is hard for a doctor to choose and maintain the right dose of warfarin for each patient. Too much or too little warfarin in the blood can cause serious health problems. A "nomogram" is a tool that helps doctors decide on the right dose of warfarin. The usual way for finding the right dose of warfarin is for doctors to take an educated guess and use a "trial and error" approach. Patients have frequent blood tests to help doctors keep track of how well the dose level is working. Up until now, if a patient had good blood test results over half of the time, that was as well as doctors could do. The purpose of this study is to see whether the investigators can create a reliable new warfarin nomogram that will allow them to dose a patient correctly more often, perhaps about 3 times out of 4. The nomogram the investigators are studying uses information about a patient's health and genes to decide on the best dose of warfarin. The investigators don't yet have a reliable, safe way to choose the correct dose. In this study, the investigators will use a genetic blood test to try to find a better way. Genes are the parts of each living cell that allow characteristics to be passed on from parents to children. The investigators know that people with certain genes seem to respond to warfarin in a certain way. From a blood sample, the investigators can look at patients' genes and try to predict the response to the blood-thinning medication. There will be about 500 subjects taking part in this study. They will come from participating Partners' Hospitals, including Brigham and Women's Hospital, Massachusetts General Hospital, Faulkner Hospital, Newton-Wellesley Hospital, Spaulding Rehabilitation Hospital, and North Shore Medical Center. The U.S. Food and Drug Administration (FDA) has approved warfarin for use as a blood thinner.

Home Treatment of Patients With Pulmonary Embolism Based on Pro-Brain Natriuretic Peptide (BNP)...

Pulmonary Embolism

The aim of this study is to investigate the safety of treatment of pulmonary embolism in an outpatient setting based on normal pro-BNP levels. The mortality rate and the incidence of hemodynamic instability as well as major bleeding and recurrent venous thromboembolism (VTE) in the outpatient group will be studied.

Anticoagulant Therapy During Pacemaker Implantation

HemorrhageThrombosis1 more

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.

A Study of Dalteparin Prophylaxis in High-Risk Ambulatory Cancer Patients

Venous ThromboembolismPulmonary Embolism

Some cancer patients starting a new chemotherapy regimen are likely to develop blood clots, also known as venous thromboembolism (VTE). Blood clots can cause symptoms and can occasionally be life-threatening. The purpose of this study is to determine if a daily injection of a blood-thinner, dalteparin, for 12 weeks can safely and effectively reduce the frequency of blood clots. Dalteparin is currently approved for prevention of blood clots following surgery and in hospitalized patients but not specifically for cancer outpatients.

Nadroparin for the Initial Treatment of Pulmonary Thromboembolism

Pulmonary EmbolismThromboembolism2 more

Low-molecular-weight heparin (LWMH) appears to be at least as effective and safe as standard, unfractionated heparin (UFH)for the treatment of patients with deep vein thrombosis(DVT) and may also be so in patients with pulmonary thromboembolism (PTE). Only limited data are available on the evaluation of body weight adjusted LWMH and standard UFH for the initial treatment of PTE in Chinese population. The aim of this study is to determine whether body weight-adjusted, subcutaneous Nadroparin is as effective and safe as UFH for treatment of patients with objectively documented PTE.
