Preventing cardiovascular disease in women.

Cardiovascular disease (CVD) has been the primary cause of death in women for almost a century, and more women than men have died of CVD every year since 1984. Although CVD incidence can be reduced by adherence to a heart-healthy lifestyle and detection and treatment of major risk factors, preventive recommendations have not been consistently or optimally applied to women. The American Heart Association guidelines for CVD prevention in women provide physicians with a clear plan for assessment and treatment of CVD risk and personalization of treatment recommendations. The emphasis of preventive efforts has shifted away from treatment of individual CVD risk factors in isolation toward assessment of a woman's overall or "global" CVD risk. In addition to accounting for the presence or absence of preexisting coronary heart disease or its equivalents (e.g., diabetes, chronic kidney disease), cardiovascular risk can be further calculated with the Framingham risk score, which is based on age, sex, smoking history, and lipid and blood pressure levels. Intervention intensity and treatment goals are tailored to overall risk, with those at highest risk receiving the most intense risk-lowering interventions. Women at high risk for CVD and without contraindications should receive aspirin, beta blockers, and an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker in addition to pharmacologic therapy for hyperlipidemia, hypertension, and diabetes. Women who already are at optimal or low risk for CVD should be encouraged to maintain or further improve their healthy lifestyle practices. Optimal application of these preventive practices significantly reduces the burden of death and disability caused by heart attack and stroke in women.

CardioVision 2020: program acceptance and progress after 4 years.

OBJECTIVE: To report program acceptance and progress after 4 years of a heart disease prevention program. SUBJECTS: All Olmsted County, Minnesota residents aged >/=20 years. METHODS: The analysis is based on independent population-based interview samples from 1999, 2000, 2001, and 2003; a dietary questionnaire mailed to interviewees; and blood pressure and cholesterol data from medical records of consenting Olmsted County residents. National, Minnesota, and Olmsted County Behavioral Risk Factor Surveillance System trends for fruit and vegetable consumption, body mass index, participation in physical activity, and smoking are compared. The data were analyzed in 2005. RESULTS: More than 90% of the population considers CardioVision 2020 to be a good, very good, or excellent idea. The program is associated with a 25% reduction in the number of people exposed to environmental tobacco smoke and small but significant increases in consumption of fruits and daily physical activity. The population meeting the serum cholesterol goal increased from 52.0% in 1999 to 57.5% in 2003, and the population meeting the blood pressure goal increased from 53.7% in 1999 to 59.9% in 2003. However, attempts to quit smoking and the amount of time spent in physical activity did not increase. By 2003, nearly 9% of the population reported making a behavior change because of CardioVision 2020. Compared to Minnesota and national trends, fruit and vegetable consumption increased significantly in Olmsted County. CONCLUSIONS: The population of Olmsted County views CardioVision 2020 in a positive light. Positive changes in several personal behaviors and risk factor levels have occurred.

National study of physician awareness and adherence to cardiovascular disease prevention guidelines.

BACKGROUND: Few data have evaluated physician adherence to cardiovascular disease (CVD) prevention guidelines according to physician specialty or patient characteristics, particularly gender. METHODS AND RESULTS: An online study of 500 randomly selected physicians (300 primary care physicians, 100 obstetricians/gynecologists, and 100 cardiologists) used a standardized questionnaire to assess awareness of, adoption of, and barriers to national CVD prevention guidelines by specialty. An experimental case study design tested physician accuracy and determinants of CVD risk level assignment and application of guidelines among high-, intermediate-, or low-risk patients. Intermediate-risk women, as assessed by the Framingham risk score, were significantly more likely to be assigned to a lower-risk category by primary care physicians than men with identical risk profiles (P<0.0001), and trends were similar for obstetricians/gynecologists and cardiologists. Assignment of risk level significantly predicted recommendations for lifestyle and preventive pharmacotherapy. After adjustment for risk assignment, the impact of patient gender on preventive care was not significant except for less aspirin (P<0.01) and more weight management recommended (P<0.04) for intermediate-risk women. Physicians did not rate themselves as very effective in their ability to help patients prevent CVD. Fewer than 1 in 5 physicians knew that more women than men die each year from CVD. CONCLUSIONS: Perception of risk was the primary factor associated with CVD preventive recommendations. Gender disparities in recommendations for preventive therapy were explained largely by the lower perceived risk despite similar calculated risk for women versus men. Educational interventions for physicians are needed to improve the quality of CVD preventive care and lower morbidity and mortality from CVD for men and women.

Dietary intake of fruits, vegetables, and fat in Olmsted County, Minnesota.

OBJECTIVE: To assess self-reported dietary intake in the adult population of Olmsted County, Minnesota. SUBJECTS AND METHODS: We conducted a random-digit-dial telephone survey between March 1 and April 21, 1999, of 1232 adults residing in Olmsted County, Minnesota. We then mailed a structured questionnaire to the survey respondents and achieved a response rate of 732 individuals. Percentages of individuals and predictors of those who meet recommendations for intake of fruits and vegetables and for dietary fats were determined by using chi2 tests of general association and multivariate logistic regression. RESULTS: Only 16% of the population of Olmsted County reported meeting standard dietary recommendations for consuming both 5 or more servings of fruits and/or vegetables per day and no more than 30% of calories from fat. Fifty-one percent of the population was meeting neither recommendation. Women were more likely than men to report meeting both goals (22% vs 8%, P<.001), but still more women were meeting neither goal than were meeting both goals (40% vs 22%, P<.001). Multivariate logistic regression revealed the following factors to predict adherence to both goals: female sex, lower body mass index, nonsmoker, history of high cholesterol, and daily physical activity. CONCLUSION: Few individuals in Olmsted County are meeting national recommendations for intake of fruits, vegetables, and dietary fat. More effective interventions are needed to improve dietary habits in all subgroups of this community.

Controversy of hormone treatment and cardiovascular function: need for strengthened collaborations between preclinical and clinical scientists.

Over the last five years, there have been several major randomized clinical trials assessing the use of hormone therapy as an adjunct treatment for primary and secondary prevention of cardiovascular disease. Results of these trials have called into question existing dogma from epidemiological and basic science studies that estrogen provides protection against development of cardiovascular disease. When studies are evaluated for design, type and duration of hormone treatment, and outcomes, directions for future research become apparent. Improved hormone formulations and selective estrogen receptor modulators that help to maintain vascular function and limit progression of cardiovascular occlusive disease need to be developed. This will depend upon improved understanding of: (i) the distribution and regulation of estrogen receptors in vascular tissue, (ii) genomic interactions of estrogens and progestins, (iii) association of the estrogen receptor and other genetic polymorphisms with particular vascular functions, and (iv) better definition of timing and dosing for therapeutic intervention. The mechanisms of interactions between coagulation proteins, inflammatory cytokines, platelets and the vessel wall should be defined so that the thrombotic risk for an individual woman can be identified and reduced, and progression of chronic disease processes associated with loss of ovarian hormones can be slowed.

Self-reported weight, weight goals, and weight control strategies of a midwestern population.

OBJECTIVE: To elicit from individuals in a population their current weight and height, weight goals, and weight control strategies to aid in design of effective interventions to prevent and treat obesity. SUBJECTS AND METHODS: By random digit dial telephone survey, 1224 adult residents of Olmsted County, Minnesota, were contacted between February 28 and May 5, 2000. They self-reported weights and weight goals and described physical characteristics associated with their desire to lose weight. RESULTS: Among the 1224 respondents, 65.6% of men and 47.9% of women reported that they were overweight (body mass index [BMI], 25.0-29.9 kg/m2) or obese (BMI, > or =30.0 kg/m2). Only 0.4% of men and 3.7% of women reported that they were underweight (BMI, <18.5 kg/m2). Of the respondents 72.6% of men and 85.1% of women reported that they were either trying to lose or not gain weight. The average weight loss goal for individuals trying to lose weight was 23.4 pounds for men and 28.0 pounds for women. Only one third of individuals trying to lose weight and one fifth of individuals trying not to gain weight reported using the recommended approach of combining energy restriction with at least 150 minutes of exercise per week. CONCLUSIONS: The prevalence of overweight and obesity in the population and the underutilization of combining both restricting energy intake and exercising at least 150 minutes per week for weight control is high. Like the majority of people in the United States, the majority of people in Olmsted County desire to control their weight. The community has responded with plans to help residents meet their goals, although efficacy and outcomes remain to be determined.

Evidence-based medicine and treatment of hypertension in women: results of trials.

PURPOSE: The aim of this review is to summarize the evidence from randomized controlled trials and meta-analyses of hypertension treatment trials that included women in their study population and subsequent analyses. RESULTS: Most early hypertension treatment trials did not include women in their study population, or did so in insufficient numbers to assess gender-specific outcomes. Women, particularly the elderly, were better represented in subsequent studies, but gender-specific results were not often reported and most trials were not designed or powered to detect gender differences in treatment responses and outcomes. In some studies where gender-specific results have been reported, gender differences have been observed, but the direction of the effect has generally been similar in men and women. Large meta-analyses of treatment trials have found similar relative risk reductions as a result of hypertension treatment, but lower absolute risk reductions in women compared to men. Absolute risk reductions are strongly related to baseline risk and have been demonstrated in virtually all subgroups of women except those with extremely low aggregate cardiovascular risk. While there are still limited data regarding treatment benefits for young women, no subset of women has been shown to experience net harm as a result of hypertension therapy. CONCLUSION: The design and implementation of future hypertension treatment trials should include the provision to assess gender-specific differences in treatment and outcomes.
