Cardiologists have traditionally focused on coronary narrowing as seen on angiography and have orientated treatment towards bypassing these lesions or widening them with angioplasty. In patients with stable coronary artery disease, percutaneous coronary interventions reliably relieve angina and myocardial ischemia, but do not prevent myocardial infarction or reduce mortality. Cholesterol ...

Few things are better understood within the medical community than the relationship between elevated total and low-density lipoprotein cholesterol (LDL-C) levels, cardiovascular disease and death. There is consensus in the treatment guidelines of numerous national and international bodies that cholesterol levels in at-risk patients should be reduced to target levels ...
Heeschen Christopher - - 2002
BACKGROUND: HMG-CoA Reductase Inhibitors (statins) reduce cardiac event rates in patients with stable coronary heart disease. Withdrawal of chronic statin treatment during acute coronary syndromes may impair vascular function independent of lipid-lowering effects and thus increase cardiac event rate. METHODS AND RESULTS: We investigated the effects of statins on the ...
LaRosa John C - - 2002
Atherosclerosis is not an inexorable part of aging. Addressing unhealthy lifestyle behaviors will go a long way toward reducing the current burden of atherosclerosis without widespread drug therapy. The question is whether this is possible, given the demand of our modern culture. It is not yet clearly established precisely where ...

Murine models of atherosclerosis, such as the apolipoprotein E (apoE) or the LDL receptor knockout mice, usually do not exhibit many of the cardinal features of human coronary heart disease (CHD), eg, spontaneous myocardial infarction, severe cardiac dysfunction, and premature death. Here we show that mice with homozygous null mutations ...
Chan Albert W - - 2002
BACKGROUND: Long-term administration of statin therapy has been shown to reduce major coronary events and cardiac mortality within randomized clinical trials. In addition to lowering lipids, statins favorably affect platelet adhesion, thrombosis, endothelial function, inflammation, and plaque stability, which may potentially improve outcome after percutaneous coronary intervention (PCI). Therefore, we ...
Grainger D J - - 2002
BACKGROUND: Inappropriate inflammation is a key mechanism in the development of atherosclerosis. Antibodies against components of the atherosclerotic lesion, in particular, oxidised low density lipoprotein, have been described. OBJECTIVE: To determine whether a systemic autoimmune response, characterised by the presence of high titres of antinuclear antibodies, is associated with the ...

BACKGROUND: Coronary heart disease (CHD) is still the single major cause of death in our community despite the dramatic decline in prevalence over the past 20 years or so. The first presentation of CHD in up to 50% of patients is one of the acute coronary syndromes, either acute myocardial ...
Shepherd J - - 2002
OBJECTIVE: Treatment of hyperlipidemia to reduce the risk of ischemic heart disease was, prior to the statin era, disappointingly limited in its ability to yield the benefits expected from the strong relationship known to exist between serum cholesterol and coronary death. Three primary prevention trials, using clofibrate, cholestyramine and gemfibrozil, ...
Olsson Anders G - - 2002
Statins may act rapidly to reverse abnormalities of the arterial wall that may predispose to recurrent ischemic events after acute coronary syndromes. Such abnormalities are endothelial dysfunction, a local inflammatory response. and an exaggerated thrombogenic tendency. In one study almost 20,000 patients with first myocardial infarction were studied with regard ...
Athyros Vasilios G - - 2002
BACKGROUND: Atorvastatin is very effective in reducing plasma low-density lipoprotein cholesterol (LDL-C) levels. However, there is no long-term survival study that evaluated this statin. PATIENTS-METHODS: To assess the effect of atorvastatin on morbidity and mortality (total and coronary) of patients with established coronary heart disease (CHD), 1600 consecutive patients were ...
