CARDIOVASCULAR DISEASES

Cardiovascular diseases

Abstract

Cardiovascular diseases are the leading cause of death in developed countries. The inflammation, cross-sectional studies have shown that nut consumption is associated with lower concentrations of circulating inflammatory molecules and higher plasma adiponectin, a potent anti inflammatory adipokine. Clinical studies with nuts have documented reduced inflammatory cytokine concentrations but no consistent changes of Co reactive protein. The criteria for CVD diagnosis using heart ultrasound were as follows: typical enlargement of inter-ventricular septum with turbulence at the exit part of the ventricle in hypertrophic myocardiopathy and, also enlargement of all atria and ventricles in dilating myocardiopathia.

Cardiovascular Diseases

Description of the disease/condition

Cardiovascular diseases are the leading cause of death in developed countries. The target organs of cardiovascular diseases are the heart (pump-based, rhythmic function), the brain, the lungs, and kidney and leg arteries.

Some age and sex are independent but, high cholesterol, hypertension, smoking; some of the methods of diet and physical inactivity are creating problem for the body this causes such diseases. Biology and molecular genetics have revealed the many factors who act on the blood vessel. They have changed the way these diseases, and in particular the atherosclerosis whose evolution leads to blockage of a vessel and myocardial infarction.

The deposition of cholesterol in the arterial wall triggers complex phenomena that lead to the formation of atherosclerotic plaques. These plates are gradually reducing the size of the artery and can cause a myocardial infarction. Recent work would support the role of infectious agents in the development of atherosclerosis. A bacterium of the genus Chlamydia has been demonstrated in athermanous plaque (Califano, 2004).

Atherosclerosis is the main cause of cardiovascular disease. It causes hardening and thickening, loss of elasticity with deposition of fatty substances and limestone and narrowing or occlusion. It is common in men from 30 years and in women from age 40. Cardiovascular diseases are a groups of disorders of the heart and blood vessels. Although this definition makes categorized any disease process in the cardiovascular system (heart disease + vascular), in common parlance it usually refers to various diseases related to atherosclerosis. The narrowing, obstruction or excessive enlargement (aneurysm) of the blood vessels that can accompany this disease, in fact are responsible for widespread diseases, such as coronary (angina pectoris and heart attack), (stroke) and peripheral vascular diseases.

Explanations, how the various body systems are affected

Diet appears to have a multidimensional beneficial effects on cardiovascular diseases; including pathogenesis, thrombosis, antioxidants, vitamins, anti-inflammatory and lipid lowering effects. Fruit, vegetable, and nuts intake may have an independent role, separate from low fat calories and low density lipoprotein cholesterol (LDL-C). There is evidence, that antioxidants protect the LDL cholesterol from oxidation in its atherogenic product oxidized LDL which is more attractive for macrophages during development of atherosclerosis. Dietary dimensions may be provided by haemostatic factors, omega-3 fatty acids, monounsaturated fatty acids (MUFA), vitamins, flavonoids, folic acids, plant sterol, alcohol and wine. Onion, garlic, spices, green tea and other herbs could be another dimension which may have beneficial effects on human health and ...
