Aromatic plants belonging to the Lamiaceae family, besides the role that they play in imparfing taste and flavor to the food, have demonstrated their antioxidant and antimicrobial effects and other positive health benefits such as the prevention of cardiovascular diseases, atherosclerosis, or reducing the risk of cancer. Due to a long list of beneficial physiological effects that these plants have on health suggests that they might well be considered as essential and natural components of our diet. 

Other Cardiovascular Agents Effecting Atherosclerosis. A large amount of clinical data is available concerning semm Upid profiles in patients subjected to dmg therapy for other cardiovascular diseases. Atheroma, for example, may be the underlying cause of hypertension and myocardial infarction. There are on the order of 1.5 million heart attacks pet year in the United States (155). 

Thus, it is apparent that soya, some soya products and linseed oil influence blood lipid levels, particularly cholesterol and LDL cholesterol. While the extent of the reduction appears to largely depend on an individual s initial serum cholesterol level, the maximum reductions observed are of the order of 10-15%. For hyperlipidemic individuals this may not be a marked reduction, but such an effect on the general population may well have a beneficial effect on the overall incidence of cardiovascular disease and atherosclerosis. The possibility that non-phytoestrogenic dietary components may contribute to the hypocholes-terolemic properties cannot, however, be discounted. Indeed, certain types of dietary fibre have been shown to have a hypolipidemic effect via their ability to increase faecal excretion rates. 

LDL, or "bad," cholesterol builds up as a plaque-like deposit on the interior walls of arteries. This process used to be called hardening of the arteries today it is referred to as atherosclerosis. It can lead to cardiovascular diseases, including strokes and heart attacks. In contrast, HDL or "good" cholesterol retards or even reduces arterial deposits. 

Supplements of 400 Ig/d of folate begun before conception result in a significant reduction in the incidence of neural mbe defects as found in spina bifida. Elevated blood homocysteine is an associated risk factor for atherosclerosis, thrombosis, and hypertension. The condition is due to impaired abihty to form methyl-tetrahydrofolate by methylene-tetrahydrofolate reductase, causing functional folate deficiency and resulting in failure to remethylate homocysteine to methionine. People with the causative abnormal variant of methylene-tetrahydrofolate reductase do not develop hyperhomocysteinemia if they have a relatively high intake of folate, but it is not yet known whether this affects the incidence of cardiovascular disease. 

Cardiovascular disease (CVD) is one of the leading causes of death worldwide. There are a number of established risk factors including serum cholesterol levels, smoking and family history, which are responsible for between 50 and 75% of the CVD cases, with the remainder due to factors that cause atherosclerosis. Estrogen treatment such as hormone replacement therapy is known to protect against CVD by decreasing the levels of low-density... 

Carotenoids and cardiovascular diseases — Numerous epidemiological studies aimed to study the relationship of carotenoids and cardiovascular diseases (CVDs) including coronary accident risk and stroke. It appeared then that observational studies, namely prospective and case-control studies, pointed to a protective effect of carotenoids on myocardial infarct and stroke, but also on some atherosclerosis markers such as intima media thickness (IMT) of the common carotid artery (CCA) and atheromatous plaque formation. 

Atherosclerosis (AS) is a progressive disease characterized by the accumulation of lipids and the development of fibrosis in arterial walls. It is the pathophysiologic process behind cardiovascular disease whose clinical... 

The basic biology of chemokines and their receptors is well covered in Chapters 2 and 3 of this book, and we will focus hereafter upon the roles of individual chemokines and receptors in atherosclerosis. The largest amount of data on the roles of chemokines in cardiovascular disease (C VD) has been obtained from in vitro studies and murine models, which will be discussed in detail. In man, genetic polymorphisms in chemokine and chemokine-receptor genes have pointed to an important role for specific chemokines in various atherosclerotic diseases including coronary artery disease and carotid artery occlusive disease. For properties see Table 1. 

Hypertension is the most common cardiovascular disease in fact, nearly 25% of adults in the U.S. are considered hypertensive. Hypertension is defined as a consistent elevation in blood pressure such that systolic/diastolic pressures are >140/90 mmHg. Over time, chronic hypertension can cause pathological changes in the vasculature and in the heart. As a result, hypertensive patients are at increased risk for atherosclerosis, aneurysm, stroke, myocardial infarction, heart failure, and kidney failure. There are several categories of antihypertensive agents ... 

However, the mechanism for the increased incidence of cardiovascular disease in CHC users is believed to be thromboembolic and thrombotic changes, not atherosclerosis. 

Dysregulation of the vascular endothelium has emerged as a critical component of most thrombotic disorders [10, 21]. Often without any anatomical sign of atherosclerosis, many cardiovascular diseases express a vasomotor abnormality termed endothelial dysfunction, indexed clinically as impaired endothelium-dependent vasodilation [31]. Although its mechanism is multifactorial, endothelial dysfunction is characterized by diminished vascular NO production and/or bioavailability [32]. The... 

Cardiovascular disease Any abnormal condition characterized by dysfunction of the heart and blood vessels. CVD includes atherosclerosis (especially coronary heart disease, which can lead to heart attacks), cerebrovascular disease (e.g., stroke), and hypertension (high blood pressure). [NIH]... 

A high plasma concentration of LDL (usually measured as LDL-cholesterol) is a risk factor for the development of atheroma whereas a high concentration of HDL is an anti-risk factor for cardiovascular disease (CVD). Fundamental discoveries relating to cholesterol metabolism and the importance of the LDL receptor made by Nobel laureates Joseph Goldstein and Michael Brown led to an understanding of the role of LDL in atherosclerosis. The impact of HDL in reducing CVD risk is often explained by the removal of excess cholesterol from tissues and its return to the liver, a process known as reverse cholesterol transport. However, evidence from research by Gillian Cockerill and others shows that HDL has a fundamental anti-inflammatory role to play in cardioprotection. 

Many studies have shown that ginseng has a protective effect on the development of atherosclerosis that may lead to myocardial infarction and other cardiovascular diseases. The preventive effects on cardiovascular diseases of ginseng include its potential antihypertensive and antiatherosclerotic effects. Ginsenosides are likely to be responsible for some of these effects as they have been shown to have inhibitory effects on platelet aggregation and to suppress thrombin formation as well as an effect on blood vessel contraction. 

Accumulation of homocystine in blood is associated with cardiovascular disease deep vein thrombosis, thromboembolism, and stroke dislocation of the lens (ectopic lens) and mental retardation. Homocystinemia caused by an enzyme deficiency is a rare, but severe, condition in which atherosclerosis in childhood is a prominent finding. These children often have myocardial infarctions before 20 years of age. Ail patients excrete high levels of homocystine in the urine. Treatment includes a diet low in methionine. The two major enzyme deficiencies producing homocystinemia are ... 

For many years, alterations in APOE and defects in the APOE gene have been associated with dysfunctions in lipid metabolism, cardiovascular disease, and atherosclerosis. During the past 25 years, an enormous amount of studies clearly documented the role of APOE-4 as a risk factor for AD, and the accumulation of the APOE-4 allele has been reported as a risk factor for other forms of dementia and CNS disorders (1,12,18-20,47.488). 

As noted above, obesity is a health problem. It is associated with both elevated mortality and morbidity. More specifically, obesity is a risk factor for cardiovascular disease, including heart attack and stroke, and for high blood pressure (hypertension), diabetes, and hyperlipidemia (elevated levels of lipids in the blood, a risk factor for atherosclerosis and its sequelae), and for cancer.
