CRP (C-reactive protein) is an acute-phase reactant, the levels of which increase dramatically in response to severe bacterial infection, physical trauma, and other inflammatory conditions. CRP is found in human atherosclerotic lesions. Atherosclerosis is clearly multifactorial in origin, and chronic inflammation is an important component in its pathogenesis. Focus on inflammation is critical in research on atherosclerosis. Elevated levels of CRP have been associated with increased risk of future coronary artery disease (CAD) events. I have summarized the recent literature on CRP studies in CAD. Both coronary heart disease and dilated cardiomyopathy(DCM) result in congestive heart failure due to myocardial damage. The inflammatory state produced by myocarditis of viral or other origin may induce advanced myocardial damage, resulting in heart failure with a poor prognosis. Routine CRP measurement proved to be valuable for identifying high-risk patients with DCM and lymphocytic myocarditis. I suggest that measurement of circulating CRP would be useful for the diagnosis of and for selecting therapeutic strategies for cardiovascular disorders. 相似文献

Cardiovascular disease, predominantly coronary heart disease and stroke, leads to high morbidity and mortality not only in developed worlds but also in underdeveloped regions. The dominant pathologic foundation for cardiovascular disease is atherosclerosis and, as to coronary heart disease, coronary atherosclerosis and resulting lumen stenosis, even total occlusions. In translational research, several animals, such as mice, rabbits and pigs, have been used as disease models of human atherosclerosis and related cardiovascular disorders. However, coronary lesions are either naturally rare or hard to be fast induced in these models, hence, coronary heart disease induction mostly
relies on surgical or pharmaceutical interventions with no or limited primary coronary lesions, thus unrepresentative of human coronary heart disease progression and pathology. In this review, we describe the progress of animal models of coronary heart disease following either spontaneous or diet accelerated coronary lesions. 相似文献

We compared the extent of lesions in the coronary arteries of autopsied middle-aged men from Oslo, Norway, with lesions in autopsied men of similar ages in Tokyo, Japan. Certain risk factors for coronary heart disease as serum cholesterol, triglycerides, and blood pressure were also available from these men in the two locations. Our comparisons reveal large differences in the extent of atherosclerosis between Oslo and Tokyo, which are reflected in the levels of the risk factors, particularly serum cholesterol levels. Our findings suggest that preventive strategies could retard the development of atherosclerosis and coronary heart disease without the economic and nutritional problems that affect technically underdeveloped societies where atherosclerosis and coronary heart disease are not prevalent. 相似文献

Inflammation is a component of atherosclerotic plaque, but it is also a possible pathogenetic factor of acute coronary event responsible for coronary instability. Inflammatory markers are considered as new risk factors for atherosclerosis. Among others (C-reactive protein (CRP) is the best known marker of inflammatory response which is most frequently found in patients with acute myocardial infarction preceded by a period of instability. High values of inflammatory markers indicate poor prognosis after acute myocardial infarction. Therapy may lower the inflammatory component and the risk of coronary disease. Specific response of inflammatory marker during diagnostic and percutaneous coronary interventions indicates more severe coronary disease. 相似文献

Inflammation in variant angina: Is there any evidence? 总被引:3,自引:0,他引:3
Variant angina, defined as spontaneous angina pectoris associated with transient ST-segment elevation, has proved to be caused usually by episodic coronary spasm since Prinzmetal and his associates described a form of angina quite different from classic Heberden angina pectoris in 1959. Currently, coronary artery spasm is defined as reversible coronary stenosis, which limits coronary blood flow under resting conditions, and it plays an important role in ischemic heart disease, particularly in variant angina. Data available in respect of coronary vasospasm showed that it is closely related to atherosclerotic coronary artery disease, since intravascular ultrasound studies reveal atherosclerotic plaques in almost any spastic segment. Risk factors for coronary artery disease and coronary vasospasm, however, differ profoundly. Cigarette smoking is the only established risk factor. Although several candidates and predisposing factors, such as serotonin, histamine, thromboxane, and endothelin, have been described, the mediators and the pathogenesis of the disease remain unknown. There are abundant studies that inflammation plays an important role in the initiation, development as well as evolution of atherosclerosis, suggesting that atherosclerosis is an inflammation disease. The evidence regarding the role of inflammatory pathways in different clinical entities of coronary artery disease has significantly been accumulated. And also, primary studies have showed that inflammation may be a contributor for variant angina or vasospastic coronary disease is at least partially driven by inflammation. Although much more research is obviously needed, primary evidence provide us with some direction for that research. 相似文献

Systemic autoimmune diseases, which comprise a family of conditions which share common pathogenetic mechanisms, are frequently associated to cardiac involvement and to a high prevalence of ischemic coronary events often occurring at a younger age than in normal population. A large increase in mortality is related to premature atherosclerosis with coronary artery disease and stroke in patients with connective tissue diseases. Coronary heart disease is responsible for 40-50% of the death of patients with rheumatoid arthritis. Moreover, a growing body of evidence supports the view that autoimmune mechanisms are involved in the pathogenesis of cardiovascular disease. Inflammatory heart disease is a rising concern worldwide. Similar mechanisms link autoimmune diseases, including the association of increased disease with proinflammatory cytokines and the importance of regulatory mechanisms in the control of chronic inflammation. The role of the immune system in modulating atherosclerosis has recently been well documented. Studies have revealed that cellular and humoral immunity plays crucial roles in atherogenic plaque formation. This includes macrophages, CD4+ T cells and dendritic cells as well as autoantigens such as oxidized low-density lipoprotein (oxLDL), heat shock proteins and beta2-glycoprotein I. The inflammatory component is not localized to the "culprit" plaque, but it is diffused to the entire coronary vascular bed, and involves also the myocardium. The aim of the conference (2nd conference on heart, rheumatism and autoimmunity) was to focus the attention of the participants on some pathogenetic, clinical and therapeutic aspects at the boundary between cardiology and rheumatology and to encourage the debate among clinicians and basic researchers with different backgrounds and experiences. 相似文献

Inflammatory aneurysm of the aorta is not merely a variant of atherosclerosis, but more probably it is a manifestation of a peculiar systemic disease related to idiopathic retroperitoneal and mediastinal fibrosis. Rarely, aortitis and coronary arteritis may coexist with the inflammatory aneurysm; one of each of such unusual cases are described. Because inflammatory aneurysms of the aorta tend to occur in elderly persons, aortitis and coronary arteritis, when present, cannot be distinguished from the concomitant age-related atherosclerosis without a careful histologic examination. 相似文献

This article describes the development of human atherosclerosis as a framework on which to integrate and incorporate the research on thrombosis and hemostasis of participants in the 1992 College of American Pathologists Conference XXII on Hemostasis and Atherosclerotic Disease. Included are the early classic studies of the morphological features of atherosclerosis, atherosclerosis in different populations, the distribution of atherosclerotic lesions among arterial segments, the topography of atherosclerotic lesions within arterial segments, and the relationship of risk factors for coronary heart disease to the arterial lesions of atherosclerosis. Special attention is given to the development of atherosclerosis in young people, including findings from the Pathobiological Determinants of Atherosclerosis in Youth study. The data in this review provide confirmation of the development of atherosclerosis at an early age and relate atherosclerotic lesions to certain coronary heart disease risk factors. Any role of thrombosis or hemostasis in atherosclerosis must be integrated into this framework. 相似文献
