ABSTRACT: Both isolated systolic hypertension (>140 mm Hg/<90 mm Hg) and systolic/diastolic hypertension (>140 mm Hg/>90 mm Hg) are major risk factors for cardiovascular disease in the elderly. Specific antihypertensive drug therapy is available if lifestyle interventions fail to reduce blood pressure to a normal level. Diuretics and beta blockers both reduce the occurrence of adverse events related to cerebrovascular disease; however, diuretics are more effective in reducing events related to coronary heart disease. Treated patients are less likely to develop severe hypertension or congestive heart failure. In most instances, low-dose diuretic therapy should be used as initial antihypertensive therapy in the elderly. A long-acting dihydropyridine calcium channel blocker may be used as alternative therapy in elderly patients with isolated systolic hypertension. Trials are being conducted to evaluate the long-term effects of angiotensin converting enzyme inhibitors and angiotensin-II receptor blockers in elderly patients with uncomplicated hypertension.
ABSTRACT: Lowering cholesterol can reduce the incidence of coronary heart disease. Treating hypertension reduces overall mortality and is most effective in reducing the risk of coronary heart disease in older patients. Smoking cessation reduces the level of risk to that of nonsmokers within about three years of cessation. Aspirin is likely to be an effective means of primary prevention, but a group in whom treatment is appropriate has yet to be defined. Evidence that supplementation with vitamin A or C reduces the risk of coronary heart disease is inadequate; the data for use of vitamin E are inconclusive. Epidemiologic evidence is sufficient to recommend that most persons increase their levels of physical activity. Lowering homocysteine levels through increased folate intake is a promising but unproven primary prevention strategy. Hormone replacement therapy was associated with reduced incidence of coronary heart disease in epidemiologic studies but was not effective in a secondary prevention trial.

ABSTRACT: Clinical use of antioxidant vitamin supplementation may help to prevent coronary heart disease (CHD). Epidemiologic studies find lower CHD morbidity and mortality in persons who consume larger quantities of antioxidants in foods or supplements. Clinical trials indicate that supplementation with certain nutrients is beneficial in reducing the incidence of CHD events. Recent studies show that supplementation with antioxidant vitamins E and C have benefits in CHD prevention; however, supplementation with beta-carotene may have deleterious effects and is not recommended. Current evidence suggests that patients with CHD would probably benefit from taking vitamin E in a dosage of 400 IU per day and vitamin C in a dosage of 500 to 1,000 mg per day. Clinicians may also want to consider vitamin supplementation for CHD prevention in high-risk patients. Folate lowers elevated homocysteine levels, but evidence for routine supplemental use does not yet exist. Other nutritional supplements are currently under investigation.
Managing Menopause - Article
ABSTRACT: Many women will spend one third of their lifetime after menopause. A growing number of options are available for the treatment of menopausal symptoms like vasomotor instability and vaginal atrophy, as well as the long-term health risks such as cardiovascular disease and osteoporosis that are associated with menopause. Currently, hormone replacement therapy (estrogen with or without progestin) is the primary treatment for the symptoms and long-term risks associated with menopause. However, recent evidence calls into question the protective effect of estrogen on cardiovascular disease risk. The association of risk for breast cancer with estrogen replacement therapy also has not been fully clarified. In addition, many women cannot or choose not to take hormones. For treatment of osteoporosis and heart disease, pharmacologic choices include antiresorptive agents such as bisphosphonates and calcitonin, and estrogens or selective estrogen receptor modulators such as raloxifene. In addition, complementary options that include vitamins, herbal treatments, exercise and other lifestyle adaptations are gaining increased interest. The growing number of choices and questions in this area emphasizes the need to individualize a treatment plan for each woman to meet her specific needs.
