Complications related to arteriosclerosis account for about half of all deaths in the United States. For example, arteriosclerosis of coronary vessels is responsible for coronary artery disease (CAD), and arteriosclerosis of arteries supplying the brain can lead to strokes, or cerebrovascular accidents (CVAs). Arteriosclerosis takes two major forms: Atherosclerosis (ath-er-ō-skler-Ō-sis; athero, "fatty degeneration") is the formation of lipid deposits (plaque) in the tunica media associated with damage to the endothelial lining. It is the most common form of arteriosclerosis. Focal calcification is the deposition of calcium salts following the gradual degeneration of smooth muscle in the tunica media. Some focal calcification is a part of the aging process. It may also develop in association with atherosclerosis. A normal coronary artery is shown in Figure a, and a typical lesion, called a plaque (PLAK), is shown in Figures b and c. Elderly people--especially elderly men--are most likely to develop atherosclerotic plaques. Estrogen may slow plaque formation. After menopause, when estrogen production decreases, the risks of CAD, myocardial infarctions (heart attacks), and CVAs in women increase markedly. In addition to advanced age and male sex, other important risk factors for atherosclerosis include high blood cholesterol level, high blood pressure, and cigarette smoking. Diabetes mellitus, obesity, and stress can promote the development of atherosclerosis in both men and women. Evidence also indicates that at least some forms of atherosclerosis may be linked to chronic infection with Chlamydia pneumoniae, a bacterium responsible for several types of respiratory infections, including some forms of pneumonia. Potential treatments for atherosclerotic plaques include catheterization with balloon angioplasty and stenting, and bypass surgery. In the many cases where changes in diet do not lower circulating cholesterol levels sufficiently, drug therapies can bring them under control. Without question, the best approach to atherosclerosis is to avoid it by eliminating or reducing associated risk factors. Suggestions include (1) reducing your intake of dietary cholesterol, saturated fats, and trans fatty acids by restricting consumption of fatty meats, egg yolks, and cream; (2) not smoking; (3) checking your blood pressure and taking steps to lower it if necessary; (4) having your blood cholesterol level checked annually; (5) controlling your weight; and (6) exercising regularly. Part A Excess plasma lipids in the form of cholesterol contribute to the formation of atherosclerotic plaques within blood vessel walls. Which of the following is NOT a likely consequence of such plaques? ANSWER: increased pressure due to a loss of elasticity in the vessel wall turbulent blood flow around the plaque more resistance to flow due to a decrease in blood vessel diameter All of the listed responses are likely consequences of plaques. Correct Part B Atherosclerotic plaques in their early stages can be reduced through lifestyle changes. Which of the following lifestyle changes would NOT be effective?
