Vascular Disease

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 is occluded.
" And unlike "Functional" PVD, these above-mentioned changes in vessels are not temporary.

What are the signs and symptoms of PVD? According to the Townsend Letter for Doctors and Patients (Barker, et al., 2003), there are "many predisposing factors," including: High Blood Pressure; Diabetes; a family history of members with diabetes or other cardiovascular issues such as stroke, myocardial infarction and hypertension; "Aching or cramping in the legs while exercising that resolves upon rest"; pain in the feet or toes at night; wounds that heal slowly; a history of smoking cigarettes; being overweight; the regular consumption of fried and heavily-fatty foods; and a lack of regular exercise.

Some two million people currently suffer from PVD, according to Meletis, and PVD is the "leading cause of amputations" in the U.S. One of the debilitation effects of PVD is stasis ulcers - those are ulcerations that appear on legs as a result of reduced blood flow through legs; the age group most closely associated with stasis ulcers is the elderly. One way to lesson the severity of stasis ulcers is through increased physical activity, which helps….....

this juncture, risk factors typically exist and grow, including higher risks of contracting cardiovascular disease. Similarly, cardiovascular disease onset, particularly CAD (coronary artery disease), cerebrovascular disease, and peripheral vascular disease may transpire as well, which lead to elevated global mortality and morbidity levels (Magalhaes, Cavalcanti & Cavalcanti, 2010). Several sources have issued pre-diabetes prevalence figures, which depict pre-diabetes levels between 5.8 and 35% in individuals aged 20+. Reported rates differ based on what criteria are utilized for defining pre-diabetes. Nevertheless, the condition has grown in prevalence in the past few decades. 1988-94 and 1999-2010 National Health and Nutrition Examination Survey data comparisons reveal that pre-diabetes grew in prevalence from about 5.8% to 12.4% in these duration. It… Continue Reading...
