Arteriosclerotic vascular disease manifests as heart disease, stroke, aortic aneurysms, and peripheral vascular disease, and is a growing problem world-wide. The preventive efforts made so far have demonstrated that lowering LDL-C is one action that individuals and populations can do with significant success in delaying the onset of clinical events. Epidemiological studies and small clinical trials suggest that more aggressive and sustained lowering to LDL-C below 100 mg/dl could result in 50 to 70% reductions in vascular death. The full benefit of reducing LDL-C is only now being tested in adequate clinical trials.

Smoking is an important cause of morbidity and mortality, and is considered the most important preventable cause of disease and death in the developed world. It is a cause of cancer, heart disease, stroke, chronic obstructive pulmonary disease and pregnancy complications. Even though smoking is known as an important health hazard, tobacco use remains surprisingly high. In Portugal, 18% of the adult population smokes, and the prevalence of adolescent smoking has risen dramatically during the 90s. A significant percentage of actual smokers are willing to quit, creating a major responsibility for health care providers. Cardiologists bear a special responsibility, because there is good observational evidence that patients with coronary disease that quit smoking significantly lower their risk of recurrent ischemic events or death, and patients with peripheral vascular disease or stroke also get benefits, with better exercise tolerance, diminished rates of limb amputation, increased survival and less stroke recurrence. We wrote this paper to summarize the main recommendations on techniques of smoking cessation, based on evidence-based recommendations.

Systemic hypertension is a common condition associated with significant morbidity and mortality. Hypertension confers cardiovascular risk by causing target-organ damage that includes retinopathy in addition to heart disease, stroke, renal insufficiency and peripheral vascular disease. The recognition of hypertensive retinopathy is important in cardiovascular risk stratification of hypertensive individuals. This review reevaluates the changing perspectives in the pathophysiology, classification and prognostic significance of fundal lesions in hypertensives.

The prevalence of marked obesity is increasing rapidly among adults and has more than doubled in 10 years. Sixty-one percent of the adult population of the United States is overweight or obese. Americans are the fattest people on earth. Paradoxically these increases in the numbers of persons who are obese or overweight have occurred during recent years when Americans have been preoccupied with numerous dietary programs, diet products, weight control, health clubs, home exercise equipment, and physical fitness videos, each "guaranteed" to bring rapid results. Overweight and obesity are also world problems. The World Health Organization estimates that 1 billion people around the world are now overweight or obese. Westernization of diets has been part of the problem. Fruits, vegetables, and whole grains are being replaced by readily accessible foods high in saturated fat, sugar, and refined carbohydrates. Since class 3 obesity (morbid or extreme obesity) is associated with the most severe health complications, the incidence of hypertension, stroke, heart disease, diabetes, and peripheral vascular disease will increase substantially in the future. Recently, obesity alone has been implicated in the development of cardiac hypertrophy and CHF. The metabolic syndrome associated with abdominal obesity, which includes insulin resistance, dyslipidemia, and elevated CRP levels, identifies subjects who have an increase in cardiovascular morbidity and mortality. Twenty to 25% of the adult population in the United States have the metabolic syndrome, and in some older groups this prevalence approaches 50%. The prevalence of overweight children in the United States has also been increasing dramatically, especially among non-Hispanic blacks and Mexican-American adolescents. Overweight children usually become overweight adults. Atherosclerosis begins in childhood. The degree of atherosclerotic changes in children and young adults can be correlated with the presence of the same risk factors seen in adults. As health providers, our direction is obvious!

This review will be restricted to measures aimed at primary prevention of cancer; reduction of the death rate through screening will not be covered. In many instances, cancer prevention is just one outcome of the benefits of good health practices, which may also benefit cardiovascular, lung, infectious, and metabolic diseases. Thus, reducing tobacco smoking will bring benefits in heart disease, neonatal and maternal health, stroke, and peripheral vascular disease as well as a variety of cancers, while dietary advice appropriate to cancer risk reduction will bring benefits in diabetes, stroke, kidney, and heart disease.

High blood pressure (HBP) is a major risk factor for heart disease and stroke, end-stage renal disease, and peripheral vascular disease and is a chief contributor to adult disability. Approximately one in four adults in the United States has hypertension. Although effective therapy has been available for more than 50 years, most persons with hypertension do not have their blood pressure (BP) under control. National health objectives for 2010 include reducing the proportion of adults with HBP to 16% (baseline: 28%), increasing the proportion of adults with hypertension who are taking action to control it to 95% (baseline: 82%), and increasing the proportion of adults with controlled BP to 50% (baseline: 18%). During 1990-2000, the prevalence of hypertension, the percentage of those with hypertension who were aware of their condition, and treatment and control of hypertension increased among non-Hispanic whites, non-Hispanic blacks, and Hispanics. CDC analyzed data from the National Health and Nutrition Examination Surveys (NHANES) for 1999-2002. This report summarizes the results of that analysis, which determined that racial/ethnic disparities in awareness of, treatment for, and control of hypertension persist. If national health objectives are to be met, public health efforts must continue to focus on the prevention of HBP and must improve awareness, treatment, and control of hypertension among minority populations.

Cardiovascular disease and its subset coronary heart disease are leading causes of morbidity and mortality in the United States and worldwide. In general, higher levels of low-density lipoprotein cholesterol are associated with an increased risk of coronary heart disease, myocardial infarction, and stroke. Reducing dietary fat can improve total cholesterol levels, but consequent reductions in cardiovascular outcomes are not well documented. The Mediterranean diet is the only dietary intervention associated with a reduction in all-cause mortality. Treatment with cholesterol-lowering medications decreases the rate of cardiovascular events, but a reduction in all-cause mortality with these agents has been found only in patients with pre-existing coronary heart disease. Drug treatment in patients with a history of heart disease and average-to-high cholesterol levels can decrease the risk for stroke. In patients with peripheral vascular disease, treatment of elevated cholesterol levels may slow disease progression.

The Cochrane Collaboration provides growing and readily accessible resources to help ensure that medical decision-making is based on detailed, methodical, and up-to-date reviews of the best available evidence. We analyzed systematic reviews in the field of pediatric cardiology published by the Cochrane Collaboration's 50 Collaborative Review Groups. We found a total of 20 systematic reviews: 13 published by the Cochrane Neonatal Group, 6 by the Cochrane Heart Group, and 1 by the Cochrane Peripheral Vascular Disease Group. Systematic reviews in pediatric cardiology appear infrequently. They only concern evidence-based decision-making in the therapeutic management of patent ductus arteriosus and arterial hypotension in preterm infants, and in the management of children with Kawasaki disease. The quality of the clinical trials contained in the systematic reviews of acute rheumatic fever or obesity in children is limited. Consequently, the reviewers' conclusions provide an inadequate basis for inferring probable effects in clinical practice. In pediatric cardiology, many therapies continue to be used without supportive evidence. We found no systematic reviews of important cardiologic topics in childhood such as heart failure, shock, hypertension, congenital cardiopathy, and arrhythmia. Clinical practice guidelines complement systematic reviews, which can recommend only strategies that are supported by strong evidence or suggest further research when scientific evidence is inadequate.

Hypertension and osteoporosis are two major chronic diseases affecting the elderly. A cross-sectional study of 3887 Chinese men (n = 1958) and women (n = 1929) was used to explore the association between angiotensin converting enzyme inhibitor (ACEI) use and bone mineral density (BMD). The participants were aged 65 years and above, and were recruited using a combination of private solicitation and public advertising from community centers, housing estates, and the general community in Hong Kong. Demographic, medical, and lifestyle information was obtained from face to face interviews using standardized questionnaire, and physical examination measurements included anthropometry, tibial, and brachial systolic blood pressures, femoral neck, total hip, and lumbar spine BMD. In multiple regression analyses, after adjusting for age, weight, height, thiazide, beta-blocker, calcium channel blocker, statin, corticosteroid, and calcium supplement use, history of diabetes, heart disease, peripheral vascular disease, cigarette smoking, alcohol intake, and physical activity level, ACEI use was associated with higher femoral neck BMD (+0.015 g/cm2, P = 0.035) in women, and higher femoral neck (+0.015 g/cm2, P = 0.017), total hip (+0.016 g/cm2, P = 0.021), and lumbar spine (+0.043 g/cm2, P < 0.001) BMD in men. Thiazide use was associated with higher BMD at all three sites in general, although associations with BMD increase at the total hip (P = 0.07) and femoral neck (P = 0.09) were weak in men. Calcium channel blocker use was only significantly associated with BMD increase at the lumbar spine (P = 0.03) in women, and beta-blocker use did not have significant associations with BMD at any site. This study suggests that in addition to thiazide diuretics ACEI may have possible benefits in treating not only hypertension but also osteoporosis among older Chinese.

Treatment of migraine presents special problems in the elderly. Co-morbid diseases may prohibit the use of some medications. Moreover, even when these contraindications do not exist, older patients are more likely than younger ones to develop adverse events. Managing older migraine patients, therefore, necessitates particular caution, including taking into account possible pharmacological interactions associated with the greater use of drugs for concomitant diseases in the elderly. Paracetamol (acetaminophen) is the safest drug for symptomatic treatment of migraine in the elderly. Use of selective serotonin 5-HT(1B/1D) receptor agonists ('triptans') is not recommended, even in the absence of cardiovascular or cerebrovascular risk, and NSAID use should be limited because of potential gastrointestinal adverse effects. Prophylactic treatments include antidepressants, beta-adrenoceptor antagonists, calcium channel antagonists and antiepileptics. Selection of a drug from one of these classes should be dictated by the patient's co-morbidities. Beta-adrenoceptor antagonists are appropriate in patients with hypertension but are contraindicated in those with chronic obstructive pulmonary disease, diabetes mellitus, heart failure and peripheral vascular disease. Use of antidepressants in low doses is, in general, well tolerated by elderly people and as effective, overall, as in young adults. This approach is preferred in patients with concomitant mood disorders. However, prostatism, glaucoma and heart disease make the use of tricyclic antidepressants more difficult. Fewer efficacy data in the elderly are available for selective serotonin reuptake inhibitors, which can be tried in particular cases because of their good tolerability profile. Calcium channel antagonists are contraindicated in patients with hypotension, heart failure, atrioventricular block, Parkinson's disease or depression (flunarizine), and in those taking beta-adrenoceptor antagonists and monoamine oxidase inhibitors (verapamil). Antiepileptic drug use should be limited to migraine with high frequency of attacks and refractoriness to other treatments. Promising additional strategies include ACE inhibitors and angiotensin II type 1 receptor antagonists because of their effectiveness and good tolerability in patients with migraine, particularly in those with hypertension. Because of its favourable compliance and safety profile, botulinum toxin type A can be considered an alternative treatment in elderly migraine patients who have not responded to other currently available migraine prophylactic agents. Pharmacological treatment of migraine poses special problems in regard to both symptomatic and prophylactic treatment. Contraindications to triptan use, adverse effects of NSAIDs, and unwanted reactions to some antiemetics reduce the list of drugs available for the treatment of migraine attacks in elderly patients. The choice of prophylactic treatment (beta-adrenoceptor antagonists, calcium channel antagonists, antiepileptics, and more recently, some antihypertensive drugs) is influenced by co-morbidities and should be directed at those drugs that are believed to have fewer adverse effects and a better safety profile. Unfortunately, for most of these drugs, efficacy studies are lacking in the elderly.
