Nutraceuticals and specifically vitamins, oils and herbs are increasingly being taken by patients. Some supplements may improve cardiovascular outcome, most are unproved, and some could potentially cause harm. Marine lipid supplementation needs to be considered in all patients who have manifest coronary heart disease. For most supplements more data are ...

Acute coronary syndromes contribute significantly to the patterns of morbidity and mortality in the elderly. A meta-analysis of the pathology of acute myocardial infarction has shown that 80-90% of episodes result from the rupture of small, unstable lesions that cause <70% diameter stenosis. Statins have been shown to stabilize the ...

Three-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase inhibitors (statins) reduce coronary events and death in both primary and secondary prevention trials. In these trials benefit did not appear for years after randomization. It is noteworthy that these trials did not include patients with recent myocardial infarctions or unstable angina. It is well known that ...

Remarkable therapeutic advances in the treatment of acute coronary syndromes (ACS) have been made with antiplatelet and antithrombotic therapy. However, these therapies alone do not appear to completely stabilize culprit lesions. Evidence from a variety of sources suggests that intensive cholesterol lowering with statins favorably influences culprit lesion stabilization in ...

In the past, we believed that atherosclerosis gradually and progressively led to the complete occlusion of an artery, thereby causing acute coronary events. However, we now understand that rupture of a nonstenotic, yet vulnerable atherosclerotic plaque frequently leads to an acute coronary syndrome. Rupture-prone plaques typically have a thin fibrous ...
Waters D D - - 2001
Cholesterol lowering with statins reduces coronary events in a primary-prevention setting and in patients with stable coronary disease. However, where the risk of a coronary event is highest, in the early months after an episode of unstable angina or non-Q-wave infarction, the effect of statin therapy has not been evaluated ...

Small low-density lipoprotein (LDL) particle size has been hypothesized to be a risk factor for coronary heart disease (CHD). Animal models link large LDL to atherosclerosis. However, the strong association between small LDL and other risk factors, particularly triglyceride levels, impedes determining whether LDL size independently predicts CHD in humans. ...

C-reactive protein (CRP) is the prototype acute phase reactant and therefore a marker of systemic inflammation. In the last decades, accumulating data have demonstrated the role of inflammation in the pathogenesis of ischemic heart disease. High CRP levels, measured by high-sensitivity methods, on admission have a short-term negative prognostic value ...
Pieper J A - - 2001
The death rate from coronary heart disease (CHD) declined by 25% in the United States during 1987-1997, but the actual number of deaths fell by only 9%. Modifiable risk factors for CHD include hypertension, elevated low-density lipoprotein cholesterol, reduced high-density lipoprotein cholesterol, cigarette smoking, and diabetes. Several randomized clinical trials ...
Ansell B J - - 2001
Much has been learned about preventing and treating coronary heart disease (CHD) since publication of the National Cholesterol Education Program (NCEP) Adult Treatment Panel II (ATP II) guidelines in 1993. Even with the recent release of the ATP III guidelines, clinical decision making has become increasingly complex as a result ...
Chilton R J - - 2001
Until recently, arterial stenosis and occlusion due to buildup of atherosclerotic plaque were recognized as the primary causes of coronary heart disease (CHD). Currently, CHD is viewed as a lifelong process of endothelial inflammation, thrombosis, and plaque instability and rupture. Lifestyle modification is an important first step in prevention of ...

A known risk factor for the development of coronary artery disease and subsequent myocardial infarction is hypercholesterolaemia. The widespread nature of this phenomenon in the western world has led to the development of agents which reduce serum cholesterol levels. One such class of agents, HMG-CoA reductase inhibitors (statins) are very ...
Doggrell S A - - 2001
The development of the HMG-CoA reductase inhibitors (the statins) has lead to important advances in the management of cardiovascular disease. There have several landmark mortality and morbidity clinical trials with the statins. The 4S (Scandinavian Simvastatin Survival Study) was the first large-scale randomised cholesterol-lowering trial to show a decrease in ...
Khurana P S - - 2001
Postmenopausal estrogen replacement, with or without progestin therapy, has a generally favorable impact on lipids, improves endothelial function, and has anti-inflammatory and antioxidant effects. These properties should favorably impact coronary risk; indeed, epidemiologic studies have consistently associated hormone replacement therapy with reduced coronary risk. Nonetheless, the Heart & Estrogen/progestin Replacement ...
Plana J C - - 2001
Lipid-lowering drugs, in particular statin treatments, have been shown to reduce the incidence of initial and recurrent coronary heart disease (CHD) events within several years of initiating therapy. This effect can be clinically detected within the first 1 to 2 years in randomized trials. Recent observational and clinical trial data ...

Statin treatment of men and women age > or = 50 with coronary artery disease (CAD) and hypercholesterolemia reduces the risk of all-cause mortality, cardiovascular mortality, coronary events, coronary revascularization, stroke, and intermittent claudication. The target serum low-density lipoprotein (LDL) cholesterol level is < 100 mg/dL in older patients with ...
Waters D D - - 2001
To date, 5 major randomized, placebo-controlled statin trials--the Scandinavian Simvastatin Survival Study, West of Scotland Coronary Prevention Study, Cholesterol and Recurrent Events trial, Long-term Intervention with Pravastatin in Ischaemic Disease, and Air Force/Texas Coronary Atherosclerosis Prevention Study--have convincingly shown that total mortality and major coronary events can be significantly reduced ...
Davies M J - - 2001
Atherosclerotic coronary disease develops over several decades and was once thought to be an inevitable, irreversible consequence of aging. Atherogenesis is an inflammatory response that occurs after injury to the endothelium. Thrombosis, because of either endothelial erosion or plaque disruption, precipitates acute coronary events. Effective lipid lowering with statins has ...
Foody J M - - 2001
Over the past several years, results of clinical trials of lipid lowering have increased our understanding of the pathophysiology of coronary atherosclerosis and ischemia. Evidence is accumulating that cholesterol lowering has potential anti-ischemic effects and may have immediate consequences that have a favorable impact on coronary events, possibly even acute ...
Gotto A M AM - - 2001
Lipid-lowering treatment with statins is effective for primary and secondary prevention of coronary artery disease in patients with either hypercholesterolemia or average cholesterol levels. Several clinical trials in progress will investigate the use of statins in entirely elderly or diabetic cohorts, and larger trials will continue to include significant numbers ...
Koga N - - 2001
Correlations between serum cholesterol levels and progression of coronary and peripheral atherosclerosis have been found in many recent studies. It has also been demonstrated that aggressive cholesterol-lowering therapy with low-density lipoprotein (LDL) apheresis, a method of LDL elimination by extracorporeal circulation, is effective not only for coronary artery disease, but ...

The genes for apolipoprotein B and microsomal triglyceride transfer protein are expressed in mouse and human heart tissue. Why the heart would express these "lipoprotein assembly" genes has been unclear. Here we demonstrate that the beating mouse heart actually secretes spherical lipoproteins. Moreover, increased cardiac production of lipoproteins (e.g., in ...

Acute myocardial infarction (AMI) is more frequent in winter months than in summer months. The aetiologic mechanisms underlying this seasonal pattern are poorly understood. We investigate whether seasonal variation of metabolic and haemostatic coronary risk factors exists, and whether this variation is more pronounced in subjects with coronary artery disease ...
Wang J - - 2001
Gelatinase B, as one of the matrix metalloproteinases, may be relevant to atherogenic plaque development and stability. Recently, a C-1562T substitution in the regulatory region of the gelatinase B gene was shown to up-regulate gelatinase B expression, which could be relevant to both the severity and stability of atherosclerotic plaques. ...

The SARIS study (effect of Statin on Atherosclerosis and vascular Remodeling assessed with Intravascular Sonography) is a prospective randomized multicenter trial designed to assess both morphological and functional cardiovascular effects of atorvastatin. Participating centers will include 50 patients with normal to mildly elevated cholesterol levels eligible for balloon angioplasty and/or ...
Albert M A - - 2001
BACKGROUND: Randomized, controlled trials demonstrate that HMG CoA reductase inhibition reduces coronary event rates in both primary and secondary prevention. In addition to reducing cholesterol levels, laboratory evidence suggests that statins also have anti-inflammatory activity, a property that may be critical for maintaining plaque stability. Recently, the inflammatory marker high-sensitivity ...
Inoue T - - 2001
OBJECTIVES: This study aimed to elucidate whether an antibody against oxidized low density lipoprotein (anti-Ox-LDL) could predict short-term coronary artery atherosclerotic lesion progression. BACKGROUND: It is still controversial whether higher levels of the anti-Ox-LDL titer are associated with atherosclerotic coronary artery disease. METHODS: In 52 patients undergoing coronary angioplasty and ...
Bonifacio D L - - 2001
BACKGROUND: Previous studies have described increased vascular calcification in renal dialysis patients. The clinical significance of this finding with respect to outcomes after percutaneous coronary intervention in this population is unknown. METHODS: We analysed a prospective interventional database at a single tertiary center and identified 41 dialysis patients who underwent ...
Den Hartog F R - - 2001
Therapy with individual 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) has been shown conclusively to diminish coronary event rates and mortality in both primary and secondary prevention. To date, scant attention has been paid to whether initiation of such regimens in the hospital phase of acute coronary syndromes might confer cardioprotective ...

A strong correlation between high serum Lp(a) levels, a genetic modification of cholesterol-low density lipoproteins (c-LDL), and increased coronary heart disease rate has been found. Transient increased serum levels of this lipoprotein during acute myocardial infarction (AMI) and surgical interventions have been found. we assessed complete lipidic pattern in a ...
Durrington P N - - 2001
BACKGROUND: Omega-3 fatty acids, such as those present in fish oil, have been reported to prolong life in myocardial infarction survivors. These fatty acids can decrease serum triglyceride concentrations, but so far the doses used in trials examining their effects on coronary end points have had only minimal triglyceride lowering ...
Barter P J - - 2001
As drugs, such as the statins, and other therapies demonstrate the ability to significantly lower levels of low-density lipoprotein cholesterol (LDL-C), one issue is whether there is a lower threshold below which no further decline in coronary heart disease occurs. Those who evaluate the data from multiple trials and conclude ...
van Hout B A - - 2001
AIMS: Treatment guidelines have been developed for both "primary" and "secondary" prevention of coronary heart disease. These should consider both the efficacy as well as the costs of such treatment, particularly the costs of treatment with HMG co-enzyme A reductase inhibitors (statins). In the context of guideline development in The ...
Ehara S - - 2001
BACKGROUND: There is accumulating data that acute coronary syndromes relate to recent onset activation of inflammation affecting atherosclerotic plaques. Increased blood levels of oxidized low density lipoprotein (ox-LDL) could play a role in these circumstances. METHODS AND RESULTS: Ox-LDL levels were measured in 135 patients with acute myocardial infarction (AMI; ...
