Coronary heart disease (CHD) is the most important cause of death and disability among older women. A 50-year-old woman has a 46% risk of having CHD and a 31% risk of dying from it. Female CHD patients have a distinct clinical presentation, which includes more severe thromboembolic disease without coronary arteriosclerosis. Syndrome X also appears to be more prevalent in women. Oestrogen deficiency may be a trigger for this syndrome. The magnitude of the effect of various risk factors may also differ between women and men. In addition, there are risk factors unique to women. Lipid profiles differ between men and women. After menopause, the lipid profile changes unfavourably, with increasing levels of LDL cholesterol and decreasing levels of HDL cholesterol. Cigarette smoking, hypertension, diabetes mellitus, and obesity are all recognised risk factors for CHD in women. It is important to recognise that risk factors for CHD differ between men and women. Advising women to quit cigarette smoking, avoid obesity, increase physical activity, and prevent and treat hypertension and hyperlipidaemia will result in a reduction in CHD risk. Additional studies are needed to further contribute to our understanding of the complex risk factors underlying the development of CHD in women.

Characteristic feature of pathogenesis, epidemiology and laboratory findings in hyperuricemia of gouty patients are studied and reasonable treatments of gout in clinical medicine are discussed. Gout is characterized by repeated arthritis attacks on the metacarpophalangeal joint of the first toe or other small joints, especially overworked joints or those exposed to cold. The arthritis attack lasts for 3.5 days and then diminishes gradually. The intervals are shortened in patients under poor hyperuricemic control but tophi formation is less frequent. Complications in combination with hyperlipidemia, diabetes mellitus, obesity and hypertension, which are compatible to syndrome X, are frequent in gouty patients and are suspected of rapidly progressing to arteriosclerosis, such as ischemic heart diseases. Hyperuricemia consists of over-production and underexcretion, which can be diagnosed by the urate clearance test. Classification is valuable for surveying the underlying diseases of secondary hyperuricemia and treating gouty patients. Underexcretion was observed in 85% of gouty patients with hyperuricemia and even the mean urate clearance in the overproduction type was significantly lower than that of normal controls, suggesting that underexcretion is a fundamental phenomenon in all gouty patients. Treatments of complications as well as those of hyperuricemia with uricosuric agents are required for clinical treatment of gouty patients.

The effects of obesity on target organ injuries and cardiovascular risk factors were examined in hypertensive subjects. The subjects were 22 obese (OB-HT) and 54 nonobese (NO-HT) men with never-treated essential hypertension, and 37 obese (OB-NT) and 50 nonobese (NO-NT) normotensive men. In these 4 groups with the average age of about 50 years, we evaluated serum lipids, glucose tolerance, and hypertensive organ injuries in the heart, kidney, and optic fundus. Although the fasting blood glucose levels were similar in the 4 groups, the area under the blood glucose curve after 75 g glucose ingestion (NO-NT 15.6, OB-NT 17.5, NO-HT 15.8, OB-HT 17.6 x 10(3) mg/dl.min; p < 0.02) and the fast serum insulin level (NO-NT 7.3, OB-NT 10.1, NO-HT 7.7, OB-HT 12.2 mU/l; p < 0.001) were increased in obese men. In OB-HT, serum HDL-cholesterol was decreased (-11%, p < 0.05) and triglycerides were increased (+ 58%, p < 0.01) comparing with NO-NT. The incidence of electrocardiographic left ventricular hypertrophy was not significantly different among the 4 groups, however, urinary albumin excretion was increased in OB-HT (NO-NT 3.0, OB-NT 3.4, NO-HT 3.6, OB-HT 4.3 mg/g creatinine; p < 0.05) and sclerotic lesions of the retinal arteries were observed even in normotensive OB-NT. These data suggest that obesity unfavorably alters lipid and glucose metabolism, and facilitates organ injuries such as arteriosclerosis and renal dysfunction in hypertensive subjects.

Dietary fatty acids show different molecular structures and thus physicochemical properties of importance regarding lipid metabolism and atherogenesis. Intake of dietary fatty acids is associated with several risk factors for arteriosclerosis including fasting and postprandial plasma lipids and lipoproteins, obesity and thrombosis. Consumption of saturated fatty acids is detrimental while that of monounsaturated and polyunsaturated fatty acids lowers the incidence of coronary heart disease, but the respective influence of the various unsaturated fatty acids ingested is still discussed. The importance of the interaction between the human gene pool and dietary fatty acids is emerging.

The clinical significance of coronary arteriosclerosis and coronary risk factors was investigated in patients with coronary spasm. Coronary spasm induction test with acetylcholine was performed in 140 consecutive patients (85 males and 55 females) with chest pain in our hospital. The patients were divided into positive, borderline, and negative groups according to the results of the test. The positive and borderline groups were categorized as the coronary contractive group. The coronary sclerosis index was used to evaluate the degree of coronary arteriosclerosis. Coronary risk factors were evaluated in terms of hypertension, diabetes mellitus, hyperlipidemia, obesity, history of smoking and drinking, and family history of cardiovascular events. Patients could be divided into 34.3% in the positive group and 23.6% in the borderline group, i.e. 57.9% in the coronary contractive group, and 42.1% in the negative group. There were more males than females in both positive and coronary contractive groups. The proportion of males in the coronary contractive group was higher in patients over 60 years of age than in patients under 60. In contrast, the proportion of females was higher in patients under 60 than in patients over 60. In male patients, the coronary sclerosis indices in the positive, borderline, and coronary contractive groups were higher than those in the negative group. The indices in female patients in the positive and coronary contractive groups were higher than the index in the negative group. There were no differences in terms of the presence or absence, or the degree of organic stenosis between spastic sites and nonspastic branches in the positive group. The history of smoking in male patients was significantly more common in the positive group than in the negative group. The family history was more relevant in female patients in the positive or coronary contractive group compared to the negative group. Moreover, the history of smoking in the coronary contractive group was significantly more common than that in the negative group. The development of coronary spasm may be determined, at least in part, by the degree of coronary sclerosis as well as by gender and age. Smoking habits in both sexes and family history in females are proposed as the most important risk factors for coronary spasm.

While the causes of obesity remain elusive, the relationship between obesity and insulin resistance is a well-established fact [1]. Insulin resistance is defined as a smaller than normal response to a certain dose of insulin, and contributes to several pathological problems of obese patients such as hyperlipidemia, arteriosclerosis and hypertension. Several pieces of evidence indicate that the cytokine tumor necrosis factor a (TNF-alpha) is an important player in the state of insulin resistance observed during obesity. In this review we will try to summarize what is known about the function of TNF-alpha in insulin resistance during obesity and how TNF-alpha interferes with insulin signaling.

According to the actual knowledge obesity is a serious, nutrition-dependent pathology with a high number of consequences. Endocrine sequence of obesity such as PCO-HAIR-syndrome (polycystic ovarian syndrome, hyperandrogenemia-insulin-resistance) with its cycle disorders and sterility are beginning already in adolescent and women of young reproductive age. With ageing more serious risks such as non-insulin dependent diabetes mellitus (NIDDM), arteriosclerosis followed by coronary disease, stroke and hypertension, metabolic syndrome and a higher prevalence of malignant diseases will appear. Based on these five risks obesity should be treated early when therapeutic strategies are more successful than in older ages. The definition of a diagnosis and the beginning of a weight reduction programme combined with intense motivating treatment as well as medical and psychotherapeutic guidance is an important preventive contribution.

Obesity gains increasing prevalence world-wide. Multifactorially caused it presents itself in numerous heterogeneous phenotypes with a wide spectrum of clinical symptoms. The full-blown female obesity syndrome is initiated already in childhood, associated with ovarian hyperandrogenaemia (polycystic ovary syndrome) in the reproductive phase, and characterised by increasing co-morbidity (cancer; metabolic syndrome; arteriosclerosis) in the postmenopausal state leading to shortened longevity. Due to the complexity of psychic, somatic and endocrine-metabolic disturbances a causal break-through in the treatment of the disease could not be achieved yet, but the enhanced basal understanding and recently investigated pharmaceutical principles might enable to improve the therapeutical approaches.

Two developments in molecular genetics will profoundly influence our understanding and the diagnosis of cardiovascular disorders. First, the identification of genes responsible for monogenic and polygenic traits by analysis of e.g. large pedigrees and affected sib pairs provides invaluable data regarding the role of specific genes in common diseases like arteriosclerosis, hypertension, diabetes, thrombosis/hemostasis and obesity. Besides the insights into the underlying pathophysiology, this knowledge will permit to identify persons at high risk for disease development. These patients can then obtain a targeted intervention. The second development is related to the availability of new analytical tools for molecular biology. New methods such as sequencing by hybridisation (SBH), DNA-array technology or matrix assisted laser desorption/ionisation-time of flight mass spectroscopy (MALDI-TOF) permit sequence analysis of complete genes within hours. Automated PCR-technologies with homogenous amplicon detection formats simplify PCR and permit its use in the routine laboratory setting. Considering cardiovascular diseases there is a number of genes involved in lipid metabolism (apolipoproteins, lipoprotein receptors, lipolytic enzymes), thrombosis/hemostasis (platelet receptors, pro- and anticoagulant proteins, fibrinogen, PAI's), hypertension (angiotensin converting enzyme, angiotensinogen) glucose metabolism (glucose transporters, enzymes) and obesity (hormones, receptors), that are interesting candidates for sophisticated genetic risk assessment. Furthermore, there are also gene candidates involved in processes of early atherogenesis and chronic inflammation such as complement proteins, cell adhesion molecules, and cellular receptors and enzymes. Most of these gene candidates were derived from pathophysiologic knowledge and subsequent epidemiological studies. However, it is foreseeable that in the coming years genes will be identified which were not known so far to be involved in cardiovascular diseases. Genetic studies will be of prime importance in this area, as is exemplified by animal models. In the long term, analysis of these candidate genes before the implementation of therapy will permit a targeted intervention approach towards high risk patients. This will reduce the overall costs of health care without reducing the quality.

In this article, the authors analyze the pathological alterations which women suffer in which menopause is assumed to be a risk factor leading to the outbreak of these pathologies. Taken together, all of these alterations present some clear nutritional considerations; therefore, adequate dietetical care, followed by women during this phase, could help in their prevention and control. These alterations are: osteoporosis, obesity, arterial hypertension, arteriosclerosis and cardiovascular diseases.
