Filter by:Autoimmune diseases are diseases in which inappropriate immune responses that have the capability of harming host cells play an important role. Evidence suggests that the presence of certain autoimmune diseases such as rheumatoid arthritis or systematic lupus erythematosus increase the risk of cardiovascular disease (CVD). However, this evidence is inconsistent for autoimmune disorders and no systematic approach has been previously used to study the relationship between a range of common autoimmune disorders and specific forms of cardiovascular diseases such as myocardial infarction, intracerebral and subarachnoid haemorrhage, or venous thrombosis. The investigators will use linked electronic health records to investigate whether commonly diagnosed autoimmune disorders are associated with increased risk of CVD development and whether effects differ in men and women and change with age.
The purpose of this study is to evaluate effectiveness and safety of Promus PREMIER in Routine Clinical Practice
This study will compare the effectiveness of best available surgical treatment with best available endovascular treatment in adults with critical limb ischemia (CLI) who are eligible for both treatment options.
This research is a Randomized, double-blind, placebo-controlled, multicenter clinical study. Chinese subjects with Ischemic Stroke.
The purpose of this study is to evaluate whether endocavitary intramyocardial injection of autologous bone-marrow-derived CD133+ cells is safe on the basis of number of adverse events, with follow-up assessments extending up to 1 year after enrolment.
The purpose of this Randomized Study to evaluate the safety and efficacy of the Excel-II DES compared to the EXCEL DES in the treatment of patients with de novo coronary artery lesions.
Patients with brain hemorrhage resulting from a ruptured aneurysm (SAH) are at risk of developing a condition called vasospasm, one or two weeks after their hemorrhage. This is a major cause of stroke and death following SAH. A special type of CT scan, called CT perfusion, analyzes regional blood flow in the brain. We hypothesize that CT perfusion scans performed on admission and day 6 post-hemorrhage will enable us to predict which patients will go on to develop vasospasm.
The purpose of this study is to evaluate whether new novel markers from the clinical electrocardiogram (EKG), which have been used as non-invasive measures of heart disease, can detect coronary artery disease in patients with chest pain. The researchers are especially interested in studying how changes in these unique waves evolve over time with rest and activity. It is hoped that the findings will be helpful in differentiating patients with cardiac chest pain at emergency departments from those with non-cardiac chest pain, as early identification can accelerate treatment and save lives. Eligible participants are those age 18 and older who have been referred for a nuclear stress test at University of Pittsburgh Medical Center Presbyterian Hospital to rule out coronary artery disease as part of their clinical care.
The purpose of this study is to determine the safety and efficacy of lowering glucose (blood sugar), in addition to endovascular therapy, after acute ischemic stroke. The study will determine if lowering glucose (blood sugar) in addition to endovascular therapy will improve 90-day functional and neurological outcomes in comparison to standard glycemic care in patients with acute ischemic stroke. The study will involve treatment of 100 (50 intensive insulin therapy and 50 standard glycemic control) non-diabetic patients presenting within 8 hours of acute ischemic stroke who have undergone endovascular therapy.
In this clinical research study the investigators will test the efficacy of an innovative, non-invasive methodology to reduce mortality and lower limb loss among high-risk medically-underserved patients with cardiovascular disease in North Philadelphia. Patients with cardiovascular disease and recent lower limb amputation will be treated with an intermittent compression device on the remaining lower limb to prevent dual amputation. The study hypothesis is that the study intervention will protect against further lower limb-loss/death and reduce cardiovascular mortality in these patients (one year effect against limb-loss/death). This study may result in better secondary prevention strategies for disadvantaged urban populations as well as the general population.
