简要总结
The combination of high blood pressure and having central obesity is an increasing important factor for heart disease in men and women. It can also lead to the early development of hardening of the arteries and increased risk of a stroke. This study will analyze patients' genetic make up to identify who may be at greater risk for heart disease and strokes in relationship to high blood pressure and central obesity.
详细描述
Obesity is an increasingly important risk factor for cardiovascular disease in men and women and is associated with the premature development of atherosclerosis, and increased risk of stroke. A classical perspective of cardiovascular risk does not adequately explain all of the cardiovascular events associated with obesity. Elevated plasma levels of plasminogen activator inhibitor type I (PAI-1) are one of the biochemical hallmarks for obesity and likely contribute the increased risk of atherothrombotic events in patients with obesity. The central hypothesis of this proposal is that the increased risk of atherothrombotic events in patients with obesity. The central hypothesis of this proposal is that vascular PAI-1 excess promotes the development of intravascular thrombosis. We will test the hypothesis that secreted factors from adipocytes have autocrine, paracrine and endocrine effects that have a deleterious effect on the fibrinolytic system, either by enhancing PAI-1 production or impairing endothelial t-PA release. From a public health perspective, there is no greater threat to America's cardiovascular health than the epidemic of obesity. It is anticipated that this study will provide new insights nto the molecular mechanisms that contribute to the development of fibrinolytic dysfunction and cardiovascular disease in obesity.
