冠状动脉粥样硬化性心脏病,指由于冠状动脉粥样硬化使管腔狭窄、痉挛或阻塞导致心肌缺血、缺氧或坏死而引起的心脏病。其病因为动脉粥样硬化,发病机制亦即动脉粥样硬化的发展过程。近年来研究证实动脉粥样硬化是一种慢性炎症疾病,炎症被认为是动脉粥样硬化的核心发病机制,参与了动脉粥样硬化发生、发展以及恶化的所有过程。人类软骨糖蛋白-39又名YKL-40,是一种新的炎症标记物,通过促进血管平滑肌细胞迁移和增殖、诱导新生血管生成、促进细胞趋化、黏附、迁移和调控细胞外基质重建等来发挥作用。血浆高水平的YKL-40与冠状动脉粥样硬化性心脏病的发病相关,而且血浆YKL-40水平的增加与冠状动脉粥样硬化病变进展独立相关,甚至在心肌梗死患者中有更高的YKL-40的表达。  相似文献

Inflammation is closely related to the pathogenesis and prognosis of cardiovascular disease (CVD). Interleukin-37 (IL-37), an anti-inflammatory IL-1 family cytokine, shifts cytokine expression from pro- to anti-inflammation via regulation of macrophage polarization and lipid metabolism. In macrophages, IL-37 functions through both intracellular and extracellular pathways to regulate the activity of NF-kB and PTEN as well as the expression of cytokines, including IL-1β, IL-6, and IL-10. Moreover, IL-37 levels are increased in the serum of patients with heart failure, atherosclerosis, and acute coronary syndrome with no evidence of anti-inflammatory effects. However, transgenic overexpression of IL-37 improves cardiac infarct and attenuates atherosclerosis plaque expansion. Hence, it is worthwhile to investigate the precise mechanism and role of IL-37 in the pathogenesis of CVD, which may provide deeper understanding of the inflammatory response in this context. This review summarizes the regulatory role of IL-37 in systematic inflammation induced by CVD and highlights recent advancements in the clinical application of IL-37 as a therapeutic agent or biomarker for diagnosis of CVD.  相似文献

Despite all the therapeutic advances in the field of cardiology, cardiovascular diseases, and in particular coronary artery disease, remain the leading cause of death and disability worldwide, thereby underlining the importance of acquiring new therapeutic options in this field. A reduction in elevated resting heart rate (HR) has long been postulated as a therapeutic approach in the management of cardiovascular disease. An increased HR has been shown to be associated with increased progression of coronary atherosclerosis in animal models and patients. A high HR has also been associated with a greatly increased risk of plaque rupture in patients with coronary atherosclerosis. Endothelial function may be an important link between HR and atherosclerosis. An increased HR has been shown experimentally to cause endothelial dysfunction. Inflammation plays a significant role in the pathogenesis and progression of atherosclerosis. In the literature, there is data that shows an association between HR and circulating markers of vascular inflammation. In addition, HR reduction by pharmacological intervention with ivabradine (a selective HR-lowering agent that acts by inhibiting the pacemaker ionic current If in sinoatrial node cells) reduces the formation of atherosclerotic plaques in animal models of lipid-induced atherosclerosis. The aim of this editorial is to review the possible role of ivabradine on atherosclerosis.  相似文献

In recent years it has been established that inflammation is a key mechanism in the pathogenesis of atherosclerosis and in coronary artery disease progression. Inflammation is a host response to a wide variety of tissue injuries. A persistent or continually repeated insult will lead to chronic inflammation which may result in tissue destruction and/or loss of normal organ function. Atherosclerosis and other pathologies involving inflammation are associated with increased levels of cytokines, which in turn raise acute-phase proteins levels in blood (acute inflammation markers, i.e. fibrinogen and C-reactive protein). It has been shown recently that concentrations of these proteins are higher in individuals at increased risk of developing cardiac events in the years to come. This is true both in apparently healthy men and women and in ischaemic heart disease patients. CRP is currently the inflammatory marker which appears to have captured the investigators' attention around the globe. In this report we review the current data on the relationship between atherosclerosis and inflammation, with special attention to cytokines and acute phase reactants. The use of acute phase reactants as prognostic risk markers in ischaemic heart disease is also discussed.  相似文献

Peripheral artery disease is 1 of 3 major clinical manifestations of atherosclerosis, the other 2 being coronary artery and cerebrovascular disease. Despite progress in surgery, antithrombotic therapy and therapies that modify conventional risk factors (lipid-, blood pressure-, and glucose-lowering interventions), patients with peripheral artery disease have an unacceptably high risk of vascular complications. Additional strategies to reduce this residual risk are needed. The accumulated evidence that inflammation plays an important role in the pathogenesis of atherosclerosis has spurred recent efforts to evaluate anti-inflammatory agents as an additional therapeutic approach for atherothrombosis prevention and treatment. In this review, we examine the evidence supporting the role of inflammation in atherosclerosis, review recent trials of anti-inflammatory approaches to reduce cardiovascular complications, and offer insights into the opportunities for novel anti-inflammatory strategies to reduce the burden of cardiovascular and limb complications in patients with peripheral artery disease.  相似文献

Over the past decade, research in blood platelet physiology has led to the suggestion that platelets play an important part in the pathogenesis and complications of coronary artery disease. Occlusive intravascular platelet aggregates have been shown to cause ischemic myocardial damage in the experimental animal and to be present in some patients who die suddenly. The interplay between endothelial damage and platelet aggregation has been implicated in the etiology of atherosclerosis. Products released from platelets during aggregation may cause arterial spasm. Patients with overt ischemic heart disease and with the risk factors associated with coronary artery disease have been found to have abnormally reactive platelets.

Clinical studies of drugs that inhibit platelet aggregation have been reported to show a beneficial effect in preventing cardiac deaths or myocardial infarction; other studies have been negative or shown only a trend toward benefit. This report reviews the theoretical and experimental basis for the platelet hypothesis and the current data on the use of antiplatelet drugs in patients with coronary disease.  相似文献
