Active clinical trials for "Heart and Blood Diseases"

The aim of the study is to compare the diagnostic value of this non-invasive vascular imaging tool with the established vascular diagnostic methods for PAD in order to get prognostic data. A higher sensitivity of Fluorescence angiography in order to recognize progression of critical limb ischemia could lead to earlier therapeutic interventions and thereby increase limb salvage. A diagnostic gap would be closed.

The aim of this study is to to analyze if it is possible to reach the goals of HbA1c <7.0% and blood pressure <= 130/80 mm Hg in a cohort of patients with type 2 diabetes attending a primary care unit, using ony those resources available at the unit, and provided by the Brazilian National Health System. It is an open label, observational study, with a duration of 4-6 years. Patients attending a primary care outpatient facility will be sequentially included in the study provided they give consent. They will be followed on a monthly basis by a team of physicians and nurses. Glucose, A1c, Blood PRessure will be the outcomes.

The present study was designed to determine the prevalence of previously unknown impaired glucose tolerance and type 2 diabetes in patients with acute ST-elevation myocardial infarction subjected to acute PCI. Secondary, a possible association between inflammation, haemostasis and abnormal glucose regulation was studied.

The purpose of this study is to analyze genetic polymorphisms in genes encoding pro-inflammatory cytokines, and study the genetic predisposition to chronic periodontitis (CP) in combination with atherosclerotic cardiovascular (ACD) and aneurysmal diseases. The investigators will also try to identify oral bacteria in atherosclerotic plaques and aneurysmal walls and thrombus. Histological analyses of atherosclerotic plaques and aneurysmal wall will be performed.

To establish if there are venous obstructions in patients with neurodegenerative disorders

Atherosclerotic cardiovascular disease is the major cause of morbidity and mortality in Western societies. It is a complex genetic disorder with many genes involved and significant gene-environment interactions. The aim of the study is to identify novel genetic- and biological-markers of atherosclerosis. Atherosclerosis is assessed in the coronary arteries using coronary angiography as well as in the carotid artery (intima-media-thickness) and peripheral vessels (ankle brachial index). Association analysis of genetic and metabolic markers with atherosclerotic burden will be performed to identify novel factors of disposition to atherosclerotic vascular disease.

The purpose of this study is to determine the degree of endothelial dysfunction and inflammation in calcific aortic valve disease associated with coronary artery disease(CAD). to determine whether there is relationship between calcium metabolism and calcific aortic valve disease associated with CAD.

The purpose of this study is to develop a way to predict which patients diagnosed with idiopathic blood clots can safely stop warfarin therapy after six months. We will use patient characteristics, blood test results and imaging test results to identify those patients who have the lowest risk of developing a new blood clot after warfarin is stopped.

Cardiovascular disease is a complex multifactorial and polygenic disorder that is thought to result from an interaction between a person's genetic make up and various environmental factors. Although many studies have revealed that several genetic variants increase the risk of cardiovascular disease, the results of these studies remain controversial. The purpose of this study is to identify polymorphisms that confer susceptibility to cardiovascular disease and to clarify the adequacy of reported susceptibility gene polymorphisms. To complete this purpose, we will prospectively study over 5,000 local residents in whom relationship between these polymorphisms and occurrence of cardiovascular disease over 5 years.

As a pulmonary hypertension center, we have created a database that prospectively tracks patients with different forms of secondary pulmonary hypertension. Records include genetic analysis, and clinical and hemodynamic profiles.
