Heart and Blood Vessel Disorders
Heart and Blood Vessel: Oxygen is vital to life as it provides fuel for all the body's functions. The heart's role is to pump oxygen-rich blood to each cell within the body. The blood vessels are a network of interconnecting arteries, arterioles, capillaries, venules, and veins and provide the pathway in which blood travels. Arteries are the passageways through which the blood is delivered, the largest of which is the aorta. The aorta branches off the guts and divides into many smaller arteries, which have muscular walls that adjust their diameter to extend or decrease blood flow to a specific body area. Capillaries are thin walled, highly branched vessels that feed the tissues and collect wastes to be carried back to the lungs, liver, or kidney for elimination. Capillaries empty into the venules, which successively drain into the veins that lead back to the guts. Veins carry deoxygenated blood to the lungs to select up more oxygen, and then back to the guts once more.
The four most common types of vascular disease are high blood pressure, coronary heart disease, stroke, and rheumatic heart disease. Other forms include arrhythmias, diseases of the arteries, arterioles and capillaries, congenital defects, valvular heart disease, diseases of pulmonary circulation; and diseases of veins and lymphatics. Some of these disorders are the results of the over production of vessel cells, while others occur from vascular malformations. Still others result from inflammation of the blood vessels or the build-up of a fatty substance called plaque within the blood vessels.
Blood vessel disorder: Generally refers to the narrowing, hardening or enlargement of arteries and veins. It is often thanks to the build-up of fatty deposits within the lumen of blood vessels or infection of the vessel wall. This can occur in various locations like coronary blood vessels, peripheral arteries and veins. The narrowed arteries would block the blood supply to different organs and tissues. In severe conditions, it's going to become more critical health problems like myocardial infarct, stroke or coronary failure, which are a number of the main reasons of death. There are many causes contributing to vessel disorder including high blood cholesterol and calcium levels, blood clot formation and inflammation of arteries. It is found that age, sedentary lifestyle, diets rich in lipids, smoking, diabetes and case history of cardiovascular diseases are common risk factors. A mild degree of vessel disorder could also be asymptomatic. Blood tests on cholesterol and calcium level can be performed to monitor the risk of having the disorder. Additionally, techniques like angiography and ultrasound imaging are useful tools for diagnosis. It can be treated by both medication and surgery, depending on the type of blood vessel disorder.
Types of Blood Vessel Disorders are:
• Raynaud’s Disease
• Venous thromboembolism
