We performed a prospective study in 106 patients with acute stroke. The main purpose was to evaluate the associated diseases and to determine their prevalence and incidence in two different types of cerebrovascular disease: the intracerebral hemorrhage (HI) and ischaemic events (AI). The studied population included 54 men and 52 women with a mean age of 66.8 +/- 10.3 years. A clinical examination was performed in all patients by different specialists and all were submitted to diverse complementary tests, including a computed tomography scan of the brain (TAC) and an echocardiogram (ECO). We found 24 (23%) HI and 82 (77%) AI. In the past history, previous stroke were more prevalent in AI (p less than 0.01). Heart disease was present in 87 (82%) patients but, among them, only atrial fibrillation which was found in 19 (18%) patients, was significantly more frequent in AI (p less than 0.02). Hypertension (HTA) existed in 79 (75%) patients, respiratory complications and periferic vascular disease in 9 (8%), diabetes in 44 (42%) and dyslipidemia in 31 (29%) patients. No significant difference was found between the two groups of stroke regarding these diseases; however, there was a tendency for HTA and diabetes to be more prevalent in HI and for periferic vascular disease in AI. In the blood tests, high haematocrit was found in 35 (33%) patients, anemia in 21 (20%), hypercholesterolemia in 17 (16%), hypertrigliceridemia in 18 (17%) and uremia or creatinemia or ionic alteration in 32 (30%) patients, without any difference in their prevalence and incidence in the two groups of stroke. In conclusion, in this prospective study of patients with an acute stroke, there was 23% of HI and 77% of AI, a high prevalence of previous stroke, heart disease and HTA, but only the previous stroke and, within heart disease, the atrial fibrillation were significantly more frequent in the AI group. Also, periferic vascular disease had a tendency to be more frequent in AI, as well as diabetes and HTA had in HI.

Significant risk factors for premature coronary heart disease include: (1) family history, (2) elevated low density lipoprotein (LDL) cholesterol level > or = 160 mg/dl, l, (3) decreased high density lipoprotein (HDL) cholesterol level < 35 mg/dl, l, (4) cigarette smoking, (5) high blood pressure and (6) diabetes mellitus. All of these risk factors are common in patients with premature heart disease. Common familial lipid disorders associated with premature heart disease include familial lipoprotein(a) excess, familial dyslipidemia (elevated triglycerides and decreased HDL cholesterol), familial combined hyperlipidemia (elevations of LDL cholesterol and triglycerides, and often decreased HDL cholesterol), familial hypoapobetalipoproteinemia (elevated apolipoprotein B levels), familial hypoalphalipoproteinemia (low HDL cholesterol levels), and familial hypercholesterolemia (elevated LDL cholesterol levels). All these disorders have been characterized using age and gender specific 90th and 10th percentile values from the normal population. The diagnosis and potential management of these disorders is reviewed.

Coronary heart disease remains the most common cause of death among men and women in the United States. With an estimated cost of $56 billion annually for the treatment of heart disease, and an increasing prevalence due to aging of the population, both primary and secondary prevention of coronary heart disease take on major public health importance. New insights into the relationship between smoking, hypertension, physical activity, dyslipidemia, obesity, hyperinsulinemia and diabetes mellitus, clotting factors, and alcohol and the subsequent development of coronary heart disease are reviewed and means of intervention are highlighted. The role of aspirin, beta-blockers, calcium-channel blockers, antiarrhythmics, and angiotensin-converting enzyme inhibitors in the secondary prevention of myocardial infarction are briefly reviewed and the potential role of hormone replacement therapy in women is discussed.

The risks of cardiovascular disease associated with dyslipidemia differ in women and men, being more strongly associated with triglyceride/high-density lipoprotein in middle-aged women than in men. Although the incidence of heart disease is lower in women because they live longer, over a lifetime, cardiovascular disease in women is equal to that in men, with the greatest incidence after age 65 years. Major coronary events are rare among reproductive-age women who use oral contraceptives and are related to the concomitant effects of age, smoking, diabetes, hypertension, and obesity. Low estrogen-progestin dose oral contraceptives appear not to promote cardiovascular disease and can be used in women with controlled cholesterol elevations. Alternative contraceptive measures should be considered for patients with severe uncontrolled hypercholesterolemia or a lipid disorder that carries a high risk of coronary heart disease. In these conditions, thrombotic propensity associated with supraphysiologic doses of estrogen in oral contraceptives might accelerate coronary thrombosis should an arteriosclerotic plaque rupture. Treatment of hypercholesterolemia should follow the guidelines of the National Cholesterol Education Program and emphasize hygienic measures. Contraceptive selection in hyperlipidemic patients should reflect a balance between the risks--and their management--of developing cardiovascular disease versus the risks of pregnancy.

The purpose of this study was to investigate the prevalence of hypercholesterolemia among subjects having diabetes and glucose intolerance, according to the guidelines of the National Cholesterol Education Program (Adult Treatment Panel II, ATP II). This survey consisted of 2090 subjects (856 men, 1234 women) aged 30 years or more from the Sun-Ming district of Kaohsiung city. Glucose tolerance status was ascertained for both medical history and a 75-g oral glucose tolerance test according to World Health Organization criteria. Frequency of elevated total cholesterol in female subjects with abnormal glucose tolerance is significantly greater than in those with normal glucose tolerance (NGT). However, only male subjects with undiagnosed NIDDM (UDDM) had a statistically higher rate of hypercholesterolemia than those with NGT. Of UDDM individuals, 68% have total cholesterol level between 200 and 239 mg/dl and two or more risk factors for heart disease or evidence of coronary heart disease or total cholesterol > or = 240 mg/dl or high-density lipoprotein (HDL) cholesterol < or = 35 mg/dl. Such individuals should have their low-density lipoprotein (LDL) cholesterol measured. Using the ATP II, LDL cholesterol levels warranting dietary treatment for hypercholesterolemia would be expected in 76% of UDDM. Due to the high prevalence of coronary heart disease in diabetic patients, investigation of blood lipid levels and coronary heart disease risk factors should be routine in these patients, and treatment strategies should include management of lipid disorders and the many other risk factors. A high frequency of dyslipidemia was found among UDDM group in our study. Early detection of undiagnosed diabetic patients is also very important in decreasing the prevalence of coronary heart disease.

There is abundant evidence that the atherosclerotic process begins in childhood. Dyslipidemia is a major risk factor for atherosclerosis in adults and children. In the present study, we measured serum lipoprotein concentrations in 194 healthy children aged between 4 to 14 years. Children were grouped according to the socioeconomic status of the families, family history of essential hypertension and passive tobacco exposure. The values of total cholesterol, low density lipoprotein cholesterol and the ratio of total cholesterol/high density lipoprotein cholesterol in the low socioeconomic group were found to be significantly higher than the values obtained for the middle-high socioeconomic group. The values of total cholesterol, low density lipoprotein cholesterol, the ratio of total cholesterol/high density lipoprotein cholesterol and low density lipoprotein cholesterol/high density lipoprotein cholesterol in the passive smoker group were found to be significantly higher than those of the nonsmoker group. But, the socioeconomic level in the passive smoker group was found to be significantly lower than that of the nonsmoker group, and therefore, the impact of passive smoking on the serum lipids in children was related to socioeconomic status. A significant difference in terms of blood lipid fractions between the groups with and that without a family history of essential hypertension was not found. These results suggest that passive smoking and lower socioeconomic status are important risk factors for cardiovascular heart disease, while a positive family history of essential hypertension is not an important risk factor.

There are millions of people with coronary heart disease and tens of millions more who are at risk. Research reveals that aggressive cholesterol management, especially in patients with known coronary heart disease, reduces the incidence of clinical cardiac events and improves survival rates. A review of the literature reveals disturbing evidence that patients with dyslipidemia are not being treated according to the National Cholesterol Education Program guidelines. The need for lipid nurse specialists is real and growing; the challenge of managing care for patients with dyslipidemia is tremendous. Because the role of the lipid nurse specialist is relatively new, it is described in detail in this article. Nurses who desire to fight heart disease aggressively will find this area of nursing practice interesting, challenging, and rewarding. Nurses who facilitate the implementation of the National Cholesterol Education Program guidelines to the large numbers of patients with dyslipidemia offer a valuable public health service.

Disorders in lipid metabolism (dyslipidemia) can result to the chronic heart disease. The low density lipoprotein (LDL) is a critical subfraction of total cholesterol present in serum because it is directly linked to coronary heart disease (CHD). The growing awareness of the risks of CHD stipulates the need for more accurate and precise measurement of LDL cholesterol. Current approaches in diagnosing and monitoring CHD is largely dependent on calculated LDL (CLDL) value due to the inherent complexity of ultracentrifugation method. While friedwald's calculated formula may provide comparable values with ultracentrifugation method, it may provide a result which is different. This difference may be of clinical significance. The lipoprotein electrophoresis may be useful in measuring LDL cholesterol, in the diagnosis of type III hyperlipidemia (broad beta band) and when the triglyceride level exceeds 400 mg/dl. The result that compares the CLDL with that obtained by the electrophoresis showed a significant difference (P > or = 0.000) for LDL and insignificant difference (P = 0.068) for high density lipoprotein (HDL) cholesterol.

Dietary Guidelines have emerged over the past 30 years recommending that Americans limit their consumption of total fat and saturated fat as one way to reduce the risk of a range of chronic diseases. However, a low-fat diet is not a no-fat diet. Dietary fat clearly serves a number of essential functions. For example, maternal energy deficiency, possible exacerbated by very low-fat intakes (< 15% of energy), is one key determinant in the etiology of low birth weight. The debate continues over recommendations for limiting total fat and saturated fatty acid intake in children. Recent evidence indicates that diets with adequate energy providing less than 30% of energy from fat are sufficient to promote normal growth and normal sexual maturation. More attention needs to be devoted to the effect of dietary fat reduction on the nutrient density of children's diets. The association between dietary fat and CHD has been extensively studied. Diets high in saturated fatty acids and trans fatty acids increase LDL cholesterol levels, and in turn, the risk of heart disease. The relationship between high-carbohydrate/low-fat diets and CHD is more ambiguous because high-carbohydrate diets induce dyslipidemia in certain individuals. Obesity among adults and children is now of epidemic proportions in the United States. High-fat diets leading to excessive energy intakes are strongly linked to the increasing obesity in the United States. However, the prevalence of obesity has increased during the same time period that dietary fat intake (both in absolute terms and as a percentage of total dietary energy) has decreased. These trends suggest that a concomitant decrease in total dietary energy and modifications of other lifestyle factors, such as physical activity, also need to be emphasized. Obesity is also an independent risk factor for the development of diabetes. The current availability of fat-modified foods offers the potential for dietary fat reduction and treatment of the comorbidities associated with diabetes. However, to date, few studies have documented the effectiveness of fat-modified foods as part of a weight loss regimen or in reduction in CHD risks among individuals with diabetes mellitus. The association between total dietary fat and cancer is still under debate. While there is some evidence demonstrating associations between dietary fat intake and cancers of the breast, prostate, and colon, there are serious methodologic issues, including the difficulty in differentiating the effects of dietary fat independent of total energy intake. Reported total fat and saturated fatty acid intakes as a percentage of total energy have been declining over the past 30 years in the United States. Despite this encouraging trend, the majority of individuals--regardless of age--do not report consuming a diet that meets the levels of fat and saturated fatty acids recommended by the Dietary Guidelines for Americans. On a relative basis, saturated fat intake has gone down less than has total fat intake. Individuals of all ages who report consuming a diet with < or = 30% of energy from fat consistently have lower energy intakes. Given the increasing rates of obesity in the United States at an earlier and earlier age, dietary fat reduction may be an effective part of an overall strategy to balance energy consumption with energy needs. In each of the age/gender groups reporting consumption of < or = 30% of energy from fat and less than 10% of energy from saturated fatty acids, fat-modified foods play a more important role in their diets than for people who are consuming higher levels of fat and saturated fat. The data are clear than fat-modified foods make a more significant contribution to diets of consumers with low-fat intakes. While one cannot argue cause and effect from the results presented, the patterns of fat-modified foods/low-fat intakes are consistent. The focus on overall diet quality is often lost in the national obsession with lowering fat inta

Despite the decrease in coronary heart disease (CHD) mortality in the US in the past 30 years, CHD is the leading cause of death in men and women. Cardiovascular disease, including CHD, kills nearly 500,000 American women each year. In women, the development of CHD can be delayed by an average of 10 years compared with men, and, on average, women can experience a first myocardial infarction 20 years later than men. While CHD prevalence rates are similar in black men and white men, heart disease is not color-blind in women. Black women generally have a higher prevalence of CHD risk factors and a higher death rate at a younger age than white women. A strong family history of early onset of heart disease, increasing age, and race are unalterable factors that raise the risk of CHD. The major factors that can be modified include cigarette smoking, hypertension, diabetes mellitus, physical inactivity, obesity, dyslipidemia, estrogen level changes after menopause, and psychosocial stressors. CHD is a multifactorial process; the hazard posed by one particular risk factor is significantly influenced by other risk factors that are present, and no individual risk factor is essential or sufficient to cause CHD.
