Cardiovascular diseases are diseases of the heart and blood vessels which carry oxygen to the body’s major organs. Ischemic heart disease is the most common manifestation of cardiovascular disease. When the arteries supplying blood to the heart become occluded, the heart does not get enough oxygen. Like any muscle, oxygen is essential for the heart’s performance. Constriction of the coronary arteries will result in chest pain on exertion, or perhaps at rest. A person with such constriction might be unable to engage in activities such as walking for a prolonged period (for example, to get to a grocery store) or engaging in light or heavy housework (cleaning, cooking, etc.) buy glucotrol online
A blockage of the arteries to some or all of the heart is termed a myocardial infarction, or heart attack. The equivalent in other extremities, especially the legs, is termed peripheral vascular disease. Heart attacks can be fatal, and can lead to substantial disability if survived. A person who survives a heart attack might be unable to shop or cook, might have difficulty walking up stairs or entering a raised bathtub, and might have difficulty keeping house.
Peripheral vascular disease can lead to the same types of impairments.
Medical advance has made tremendous strides in preventing and treating coronary events. Several risk factors for heart disease are well known. Traditional risk factors include smoking; hypertension or high blood pressure; high cholesterol; obesity; family history, age and diabetes. Since the early 1970s, standard recommendations for people at risk have been behavioral changes (stop smoking, reduce weight, cut back on fat intake, and exercise) combined with medical therapy (antihypertensive medication, and more recently cholesterol-reducing medications). (Cutler and Kadiyala 2003) show significant reductions in the incidence of heart disease over time attributable to reductions in these risk factors, especially reduced smoking and better blood pressure control. There have also been technological changes in the treatment available for people with severe heart disease. Bed rest was once standard therapy for people with heart attacks. Today, therapy for a heart attack, and often heart disease in earlier stages of progression, generally starts with drugs such as aspirin help dissolve clots and restore blood flow to the heart.
