Hormone replacement therapy and cardiovascular disease: A statement for healthcare professionals from the American Heart Association
For more than 50 million American women, and millions of women in other countries who are over the age of 50 years, the decision whether or not to use estrogen replacement therapy (ERT) for chronic disease prevention is often a difficult one. Established benefits of treatment for menopausal symptoms and prevention of osteoporosis must be weighed against documented risks of therapy, including venous thromboembolic events (VTE), gallbladder disease, and a possible increased risk of breast cancer. Unopposed ERT is also associated with an increased risk of endometrial cancer in women with a uterus. Therefore, it is typically combined with a progestin and is referred to as hormone replacement therapy (HRT). The impact of ERT/HRT on cardiovascular disease (CVD) is of great public health importance, because CVD is the leading cause of death and a major contributor to disability in women.1 The purpose of this advisory is to summarize the currently available data concerning potential CVD benefits and risks associated with ERT/HRT and to provide updated clinical recommendations regarding its use in the secondary and primary prevention of CVD
Sex differences in risk factors for coronary heart disease: a study in a Brazilian population
BACKGROUND: In Brazil coronary heart disease (CHD) constitutes the most important cause of death in both sexes in all the regions of the country and interestingly, the difference between the sexes in the CHD mortality rates is one of the smallest in the world because of high rates among women. Since a question has been raised about whether or how the incidence of several CHD risk factors differs between the sexes in Brazil the prevalence of various risk factors for CHD such as high blood cholesterol, diabetes mellitus, hypertension, obesity, sedentary lifestyle and cigarette smoking was compared between the sexes in a Brazilian population; also the relationships between blood cholesterol and the other risk factors were evaluated. RESULTS: The population presented high frequencies of all the risk factors evaluated. High blood cholesterol (CHOL) and hypertension were more prevalent among women as compared to men. Hypertension, diabetes and smoking showed equal or higher prevalence in women in pre-menopausal ages as compared to men. Obesity and physical inactivity were equally prevalent in both sexes respectively in the postmenopausal age group and at all ages. CHOL was associated with BMI, sex, age, hypertension and physical inactivity. CONCLUSIONS: In this population the high prevalence of the CHD risk factors indicated that there is an urgent need for its control; the higher or equal prevalences of several risk factors in women could in part explain the high rates of mortality from CHD in females as compared to males

Impact of gonadectomy on blood pressure regulation in ageing male and female rats
Sexual dimorphism in blood pressure has been associated with differential expression of the angiotensin II (AII) receptors and with activity of the nervous system. It is generally accepted that aging affects kidney function as well as autonomic nervous system and hormonal balance. Given that hypertension is more prevalent in men than women until women reach their seventh decade we hypothesised that females would be relatively protected from adverse effects of ageing compared to males, and that this would be mediated by the protective effect of ovarian steroids. Intact and gonadectomised male and female normotensive Wistar rats aged 6, 12 and 18 months were used to study renal function, blood pressure, heart rate and blood pressure variability. We observed that intact females had lower levels of proteinuria and higher (12.5%) creatinine clearance compared to intact males, and that this difference was abolished by castration but not by ovariectomy. Ovariectomy resulted in a change by 9% in heart rate, resulting in similar cardiovascular parameters to those observed in males or gonadectomised males. Spectral analysis of systolic blood pressure revealed that high frequency power spectra were significantly elevated in the females vs. males and were reduced by ovariectomy. Taken altogether the results show that females are protected from age-related declining renal function and to a lesser extent from rising blood pressure in comparison to males. Whilst ovariectomy had some deleterious effects in females, the strongest effects were associated with gonadectomy in males, suggesting a damaging effect of male hormones
Successfully sustaining sex and gender issues in undergraduate medical education: a case study
Evidence-Based Guidelines for Cardiovascular Disease Prevention in Women
Significant advances in our knowledge about interventions to prevent cardiovascular disease (CVD) have occurred since publication of the first female-specific recommendations for preventive cardiology in 1999.1 Despite research-based gains in the treatment of CVD, it remains the leading killer of women in the United States and in most developed areas of the world.2–3 In the United States alone, more than one half million women die of CVD each year, exceeding the number of deaths in men and the next 7 causes of death in women combined. This translates into approximately 1 death every minute.2 Coronary heart disease (CHD) accounts for the majority of CVD deaths in women, disproportionately afflicts racial and ethnic minorities, and is a prime target for prevention.1–2 Because CHD is often fatal, and because nearly two thirds of women who die suddenly have no previously recognized symptoms, it is essential to prevent CHD.2 Other forms of atherosclerotic/thrombotic CVD, such as cerebrovascular disease and peripheral arterial disease, are critically important in women. Strategies known to reduce the burden of CHD may have substantial benefits for the prevention of noncoronary atherosclerosis, although they have been studied less extensively in some of these settings
