The disease known as Peripheral Vascular Disease (PVD), according to the American Heart Association (AHA, 2004), involves the blood vessels "outside the heart and brain." This disease refers to a narrowing of those vessels that carry blood to one's leg and arm muscles.
In particular, the AHA states that there are two forms of PVD: one is "Functional Peripheral Vascular Disease," and the other is "Organic Peripheral Vascular Disease." The first, Functional PVD, does not allude to actual defects in the structure of the blood vessel, but rather refers to "short-term effects" caused by cold temperatures, stress caused by emotions, smoking, or handling machinery that vibrates powerfully.
The second form of PVD - "Organic" - is actually caused by "structural changes" in blood vessels. These changes may be inflammation, tissue damage, or the buildup of fatty substances in the arteries, called "atherosclerosis" - which restricts good blood flow to the body's limbs. Atherosclerosis is particularly insidious in its attack on one's health because people "are unaware of the disease process" (Barker, et al., 2003) until "nearly 75% of the artery...
Diabetic Vascular Disease state caused by the deficiency of a chemical in the body called insulin which is a hormone is called Diabetes. There are two forms of diabetes. In the type-one diabetes no insulin is formed and people require insulin injections for existence. This was once thought it would affect only children, but now it can occur at any age. The type2 diabetes is due to the resistance of
A small number of peripheral vascular disease patients may have no symptoms. Common ones typically involve cramping and weakness in certain parts of the body, slow healing for injuries like ulcers, as well as variation in temperature and color between limbs. Treatments for this condition usually require management of cholesterol and lifestyle changes like cessation of cigarette smoke, ibuprofen, antipalet drugs, and regular exercise. One of the most common forms of
Chronic Kidney Disease Over the last several years, the issue of chronic kidney disease has been increasingly brought to the forefront. This is because when someone becomes older, the more likely they will develop this condition. According to the Center for Disease Control (CDC) and the National Kidney Foundation, once someone reaches above the age of 50, there is a 50% of them becoming susceptible to it. As they increase in
These defects or conditions are categorized according to the problems, which develop. One problem is when too much blood passes through the lungs. Another is when too little passes through the lungs. A third is when too little blood circulates in the body. And a fourth is a combination of several heart defects, presenting as a complex problem. Pediatric cardiologists are the specialists treating babies with congenital heart problems
The presence of cardiac enzymes in the blood often indicates myocardial necrosis. Medical experts generally view MI as one among acute coronary syndromes. Unstable angina and non-ST-elevation MI are among the syndromes. Statistics said that approximately 1.5 million cases come up each year. MI is a cardiovascular condition. About 12 million deaths worldwide each year are attributed to cardiovascular diseases as cause, according to the World Health Organization. These
These are high cholesterol levels, obesity, physical activity, smoking and racism. According to the 2003 report by the American Heart Association, 53% of Mexican-American men and 48% of women aged 20-74 have high bad cholesterol levels. The 1999-2000 National Health and Nutrition Examination Survey reported that 33% of Mexican-American women and 28% of men were obese, as compared with 20% of non-Hispanic women. Adolescents aged 12-19 were 24% overweight as compared
