RESUMEN

Few studies have prospectively examined lipid changes across the menopause transition or in relation to menopausal changes in endogenous hormones. The relative independent contributions of menopause and age to lipid changes are unclear. Lipid changes were examined in relation to changes in menopausal status and in levels of estradiol and follicle-stimulating hormone in 2,659 women followed in the Study of Women's Health Across the Nation (1995-2004). Baseline age was 42-52 years, and all were initially pre- or perimenopausal. Women were followed annually for up to 7 years (average, 3.9 years). Lipid changes occurred primarily during the later phases of menopause, with menopause-related changes similar in magnitude to changes attributable to aging. Total cholesterol, low density lipoprotein cholesterol, triglycerides, and lipoprotein(a) peaked during late peri- and early postmenopause, while changes in the early stages of menopause were minimal. The relative odds of low density lipoprotein cholesterol (> or =130 mg/dL) for early postmenopausal, compared with premenopausal, women were 2.1 (95% confidence interval: 1.5, 2.9). High density lipoprotein cholesterol also peaked in late peri- and early postmenopause. Results for estradiol and follicle-stimulating hormone confirmed the results based on status defined by bleeding patterns. Increases in lipids were smallest in women who were heaviest at baseline.

RESUMEN

BACKGROUND: High-density lipoprotein cholesterol (HDL-C) levels are inversely associated with cardiovascular risk. Cholesteryl ester transfer protein inhibition is one strategy for increasing HDL-C. This study evaluated the lipid-altering efficacy and safety of the cholesteryl ester transfer protein inhibitor anacetrapib as monotherapy or coadministered with atorvastatin in patients with dyslipidemia. METHODS: A total of 589 patients with primary hypercholesterolemia or mixed hyperlipidemia (53.8% of the study population had low HDL-C) were randomized equally to one of 10 groups: 5 groups received background statin therapy of atorvastatin 20 mg and 5 did not, and each of these was randomized to placebo, anacetrapib 10, 40, 150, and 300 mg once daily for 8 weeks. An equal proportion of patients had triglycerides >150 mg/dL in each group. RESULTS: For placebo and anacetrapib monotherapy (10, 40, 150, and 300 mg), least squares mean percent changes from baseline to week 8 for low-density lipoprotein cholesterol (LDL-C) were 2%, -16%, -27%, -40%, and -39%, respectively, and for HDL-C were 4%, 44%, 86%, 139%, and 133%, respectively (P < .001 vs placebo for all doses). Coadministration of anacetrapib with atorvastatin produced significant incremental LDL-C reductions and similar HDL-C increases versus atorvastatin monotherapy. For both anacetrapib monotherapy and coadministration with atorvastatin, the LDL-C reductions were similar in patients with baseline triglyceride levels greater than and less than or equal to the median. Anacetrapib was well tolerated, and the incidence of adverse events was similar for placebo and all active treatment groups. There were no increases in systolic or diastolic blood pressure in any treatment arm. CONCLUSIONS: Anacetrapib, as monotherapy or coadministered with atorvastatin, produced significant reductions in LDL-C and increases in HDL-C; the net result of treatment with anacetrapib + atorvastatin was approximately 70% lowering of LDL-C and more than doubling of HDL-C. Anacetrapib was generally well tolerated with no discernable effect on blood pressure.

RESUMEN

OBJECTIVE: Studies measuring progression of carotid artery intima-media thickness (cIMT) have been used to estimate the effect of lipid-modifying therapies cardiovascular event risk. The likelihood that future cIMT clinical trials will detect a true treatment effect is estimated by leveraging results from prior studies. The present analyses assess the impact of between- and within-study variability based on currently published data from prior clinical studies on the likelihood that ongoing or future cIMT trials will detect the true treatment effect of lipid-modifying therapies. METHODS: Published data from six contemporary cIMT studies (ASAP, ARBITER 2, RADIANCE 1, RADIANCE 2, ENHANCE, and METEOR) including data from a total of 3563 patients were examined. Bayesian and frequentist methods were used to assess the impact of between study variability on the likelihood of detecting true treatment effects on 1-year cIMT progression/regression and to provide a sample size estimate that would specifically compensate for the effect of between-study variability. RESULTS: In addition to the well-described within-study variability, there is considerable between-study variability associated with the measurement of annualized change in cIMT. Accounting for the additional between-study variability decreases the power for existing study designs. In order to account for the added between-study variability, it is likely that future cIMT studies would require a large increase in sample size in order to provide substantial probability (> or =90%) to have 90% power of detecting a true treatment effect.Limitation Analyses are based on study level data. Future meta-analyses incorporating patient-level data would be useful for confirmation. CONCLUSION: Due to substantial within- and between-study variability in the measure of 1-year change of cIMT, as well as uncertainty about progression rates in contemporary populations, future study designs evaluating the effect of new lipid-modifying therapies on atherosclerotic disease progression are likely to be challenged by large sample sizes in order to demonstrate a true treatment effect.

RESUMEN

BACKGROUND: Although smoking cessation is essential for prevention of secondary cardiovascular disease (CVD), many smokers do not stop smoking after hospitalization. Mild depressive symptoms are common during hospitalization for CVD. We hypothesized that depressive symptoms measured during hospitalization for acute CVD would predict return to smoking after discharge from the hospital. METHODS: This was a planned secondary analysis of data from a placebo-controlled, double-blind, randomized trial of bupropion hydrochloride therapy in 245 smokers hospitalized for acute CVD. All subjects received smoking counseling in the hospital and for 12 weeks after discharge. Depressive symptoms were measured during hospitalization with the Beck Depression Inventory (BDI), and smoking cessation was biochemically validated at 2-week, 12-week, and 1-year follow-up. The effect of depressive symptoms on smoking cessation was assessed using multiple logistic regression and survival analyses. RESULTS: Twenty-two percent of smokers had moderate to severe depressive symptoms (BDI >or= 16) during hospitalization. These smokers were more likely to resume smoking by 4 weeks after discharge (P= .007; incidence rate ratio, 2.40; 95% confidence interval, 1.48-3.78) than were smokers with lower BDI scores. Smokers with low BDI scores were more likely to remain abstinent than were those with high BDI scores at 3-month follow-up (37% vs 15%; adjusted odds ratio, 3.02; 95% confidence interval, 1.28-7.09) and 1-year follow-up (27% vs 10%; adjusted odds ratio, 3.77; 95% confidence interval, 1.31-10.82). We estimate that 27% of the effect of the BDI score on smoking cessation was mediated by nicotine withdrawal symptoms. CONCLUSIONS: Moderate to severe depressive symptoms during hospitalization for acute CVD are independently associated with rapid relapse to smoking after discharge and lower rates of smoking cessation at long-term follow-up. The relationship was mediated in part by the stronger nicotine withdrawal symptoms experienced by smokers with higher depressive symptoms.

RESUMEN

BACKGROUND: Recent clinical trials have shifted attention away from estrogens and toward androgens and sex hormone-binding globulin (SHBG) as potential mediators of increasing cardiovascular (CV) risk in women at midlife. METHODS AND RESULTS: The correlation between reproductive hormones and CV risk factors was evaluated in a multiethnic (white, black, Hispanic, Chinese, and Japanese) sample of 3297 premenopausal and perimenopausal women. Testosterone and estradiol (E2) were evaluated along with SHBG and the free androgen index (FAI), the amount of testosterone not bound by SHBG. Low SHBG and high FAI were strongly and consistently related to elevated CV risk factors (higher insulin, glucose, and hemostatic and inflammatory markers and adverse lipids) even after controlling for body mass index (P<0.001 for all). Low levels of E2 were associated with elevated CV risk factors to a lesser degree. These observations were consistent across the 5 ethnic groups. Compared with whites, blacks had higher levels of SHBG and lower levels of FAI, and Chinese had lower levels of SHBG and higher levels of FAI. CONCLUSIONS: Low SHBG and high FAI are strongly associated with CV risk factors in racially diverse women, and thus, androgens likely play a role in the CV risk profile of perimenopausal women.

RESUMEN

CONTEXT: Menstrual cycle characteristics may be associated with cardiovascular disease (CVD) risk. OBJECTIVE: The objective of this study was to describe the relationships between menstrual cycle characteristics and daily reproductive hormone measures with CVD risk factors in middle-aged women. DESIGN AND SETTING: Cross-sectional associations were examined between CVD risk factors and urinary LH, FSH, estrone conjugates, and pregnanediol glucuronide (Pdg) measured across one menstrual cycle or 50 d. PARTICIPANTS: Menstruating women (n = 500) who were free from diabetes or past stroke or heart attack enrolled in the Daily Hormone Study-Study of Women's Health across the Nation were studied. MAIN OUTCOME MEASURES: Body mass index (BMI), blood pressure, hemostatic, and metabolic factors were measured. RESULTS: Few differences existed in risk factors between women with evidence of luteal activity and those with no evidence of luteal activity. Associations between elevated CVD risk factors and long cycle length were reduced substantially by age and BMI adjustments. Those with lower estrone conjugate and PdG averaged across the follicular phase had higher waist circumference, triglycerides, insulin, plasminogen activator inhibitor type-1, tissue type plasminogen activator-antigen, and factor VIIc levels in age- and BMI-adjusted analyses (P < 0.05). CONCLUSIONS: In midlife menstruating women, a longer cycle length was related to CVD risk factors, in large part through their common association with BMI. More favorable levels of metabolic and hemostatic factors were associated with higher levels of follicular-phase estrogen, a pattern consistent with a more competent ovary, and higher levels of follicular-phase PdG, perhaps of adrenal origin. Metabolic and hemostatic factors may be sensitive to hormonal variation during the early perimenopausal transition.

RESUMEN

National screening guidelines for hypertension and cholesterol were applied to the multiethnic sample of perimenopausal women (N = 1349) in the Study of Women's Health Across the Nation (SWAN). To reduce low-density lipoprotein, lifestyle modification was indicated in 9.5% of patients and drug therapy in 5%. Chinese and Japanese women were least likely and African Americans were most likely to require interventions. Among all women, 27% were prehypertensive, 23% were hypertensive (blood pressure >140/90 mm Hg or treated), and 9.1% were untreated hypertensive. Untreated hypertension was lowest among Japanese and Chinese and highest among Hispanic and African-American women. Among all hypertensives, 60.5% were treated and only 58.5% of those treated were controlled. Control rates were lowest among African Americans and Hispanics. In this relatively low-risk population, a significant proportion of women with hypertension or hypercholesterolemia were either not treated, not treated adequately, or had borderline risk factors that would benefit from lifestyle interventions to prevent the need for future drug treatment.

RESUMEN

The Adult Treatment Panel III (ATP III) of the National Cholesterol Education Program issued an evidence-based set of guidelines on cholesterol management in 2001. Since the publication of ATP III, 5 major clinical trials of statin therapy with clinical end points have been published. These trials addressed issues that were not examined in previous clinical trials of cholesterol-lowering therapy. The present document reviews the results of these recent trials and assesses their implications for cholesterol management. Therapeutic lifestyle changes (TLC) remain an essential modality in clinical management. The trials confirm the benefit of cholesterol-lowering therapy in high-risk patients and support the ATP III treatment goal of low-density lipoprotein cholesterol (LDL-C) <100 mg/dL. They support the inclusion of patients with diabetes in the high-risk category and confirm the benefits of LDL-lowering therapy in these patients. They further confirm that older persons benefit from therapeutic lowering of LDL-C. The major recommendations for modifications to footnote the ATP III treatment algorithm are the following. In high-risk persons, the recommended LDL-C goal is <100 mg/dL, but when risk is very high, an LDL-C goal of <70 mg/dL is a therapeutic option, ie, a reasonable clinical strategy, on the basis of available clinical trial evidence. This therapeutic option extends also to patients at very high risk who have a baseline LDL-C <100 mg/dL. Moreover, when a high-risk patient has high triglycerides or low high-density lipoprotein cholesterol (HDL-C), consideration can be given to combining a fibrate or nicotinic acid with an LDL-lowering drug. For moderately high-risk persons (2+ risk factors and 10-year risk 10% to 20%), the recommended LDL-C goal is <130 mg/dL, but an LDL-C goal <100 mg/dL is a therapeutic option on the basis of recent trial evidence. The latter option extends also to moderately high-risk persons with a baseline LDL-C of 100 to 129 mg/dL. When LDL-lowering drug therapy is employed in high-risk or moderately high-risk persons, it is advised that intensity of therapy be sufficient to achieve at least a 30% to 40% reduction in LDL-C levels. Moreover, any person at high risk or moderately high risk who has lifestyle-related risk factors (eg, obesity, physical inactivity, elevated triglycerides, low HDL-C, or metabolic syndrome) is a candidate for TLC to modify these risk factors regardless of LDL-C level. Finally, for people in lower-risk categories, recent clinical trials do not modify the goals and cutpoints of therapy.

RESUMEN

BACKGROUND: We evaluated ethnic differences in the 10-year risk of myocardial infarction or coronary death derived from Framingham risk equation and in a composite measure of emerging cardiovascular disease risk factors in women and whether statistical adjustments for educational attainment, geographic location, and lifestyle attenuated the magnitude of the ethnic differences in risk. METHODS: Two thousand eight hundred thirty-four premenopausal women free of stroke, heart disease, or diabetes and aged of 42 to 52 years (1400 whites, 729 African American, 226 Hispanic, 231 Chinese, and 248 Japanese) had measurements of blood pressure, lipids and lipoproteins, waist circumference, glucose, insulin, lipoprotein(a), fibrinogen, factor VII, plasminogen activator inhibitor, tissue-type plasminogen activator antigen, and high-sensitivity C-reactive protein. Framingham risk score and number of risk factors in the top quartile of the distribution of risk factors not included in the Framingham score (called composite burden) were calculated. RESULTS: The unadjusted mean values for the two summary scores were higher among African Americans and Hispanics than other groups. Statistical adjustments for education and geographical site accounted for a majority of the ethnic differences, with an additional small effect of lifestyle for the composite burden score. Largest ethnic differences were apparent for waist circumference, lipoprotein(a), high-sensitivity C-reactive protein, and untreated blood pressure. CONCLUSIONS: A substantial part of the risk associated with ethnicity can be attributed to socioeconomic status and geographical location. As the ethnic composition of the United States population becomes more diverse, it is important to appreciate the cardiovascular disease risk factor burden present in some minority groups.

RESUMEN

The most recent national survey of compliance with the National Cholesterol Education Program (NCEP) Adult Treatment Panel (ATP) guidelines was completed before ATP III and showed significant underachievement of low-density lipoprotein (LDL) cholesterol goals. The NCEP Evaluation ProjecT Utilizing Novel E-Technology (NEPTUNE) II was a national survey conducted in 2003. Of the 4,885 patients, 67% achieved their LDL cholesterol treatment goal, including 89%, 76%, and 57%, respectively, in the 0 or 1 risk factor, > or = 2 risk factors or coronary heart disease (CHD), and CHD risk equivalent categories. The percentage with triglyceride concentrations > or = 200 mg/dl (2.25 mmol/L) in each risk category who achieved their LDL cholesterol and non-high-density lipoprotein cholesterol goals was 64%, 52%, and 27%, respectively. Patients with diabetes (55%) and other CHD risk equivalents (40%) were less likely to have achieved their LDL cholesterol targets than those with CHD (62%). Of the 1,447 patients with cardiovascular disease, 75% could be classified as very high risk according to the new July 2004 NCEP Writing Group recommendations, and 17.8% of those at very high risk had an LDL cholesterol level of <70 mg/dl (<1.81 mmol/L). In conclusion, these results suggest improved lipid management compared with previous surveys. The largest treatment gaps were found for features new to ATP III as of July 2004, including goal achievement for patients with CHD risk equivalents and for non-high-density lipoprotein cholesterol targets. Most of those (75%) with cardiovascular disease in NEPTUNE II would be considered very high risk and candidates for aggressive therapy to reach the new optional treatment goals.

RESUMEN

BACKGROUND: Public awareness and understanding of risk factors for atherosclerotic vascular disease are essential for successful primary and secondary prevention. The American Heart Association is committed to reducing cardiovascular disease. METHODS: A professional market survey company conducted a structured national telephone survey of English-speaking adults 40 years and older on behalf of the American Heart Association. Regional and sex quotas were imposed on the sample, and responses were weighted to match the 1999 census projections for region of the country, age, sex, and race. RESULTS: Interviews were completed with 1163 adults 40 years and older. A national probability sample of 1114 was created. Of the final sample, 28.5% were 65 years or older, 56.1% were women, and 86.5% were white. Although 91.2% of respondents stated that it was "important to them personally to have a healthy cholesterol level" (77.6% extremely or very important), 51% did not know their own level. Only 40.2% were aware of national guidelines for cholesterol management, and 53.1% either did not know or overestimated the correct desirable total cholesterol level for a healthy adult. When asked what sources of information they rely on the most, 66.8% identified physicians, while only 3.7% rely primarily on the Internet. CONCLUSIONS: Public understanding of cholesterol management is suboptimal. Physicians have a unique opportunity, on the basis of public attitudes and access, to improve cholesterol education.

RESUMEN

Two online surveys commissioned by the National Lipid Association (NLA) were conducted to determine the current attitudes of physicians and consumers regarding cholesterol and heart disease. Physicians and consumers from preexisting independent panels were randomly invited to participate in the online surveys that were open from January 26 to 30, 2004. Both physicians (n = 200) and consumers (n = 600) agreed that high cholesterol and coronary artery disease (CAD) are significant health risks. Physicians reported the primary barriers for patients being prescribed cholesterol-lowering medication as patient fear of side effects (61%) and reluctance to take prescription medications (52%). While most physicians were aware of and felt they adhered to the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) guidelines, considerably fewer thought the same of other physicians. The consumer survey focused on untreated moderate-risk patients (an approximate 10% to 20% 10-year risk of myocardial infarction and cardiac death) because this group is often undertreated. Untreated moderate-risk patients reported that their physicians did not advise them to take prescription cholesterol-lowering drugs (51%) and that they were trying to control their cholesterol with diet and exercise (58%). Consumers believe they are taking an increased role in their own health management and decision making. Current attitudes of physicians and consumers are similar with regard to their recognition of the significance of cholesterol and CAD for health, but differ with regard to why patients do not take prescription medications.

RESUMEN

The ATP III report represents an important advance from previous ATP reports dating back to the late 1980s. The guidelines are more tightly evidence-based than previous reports, partly because of evolution of the guideline process, requiring clearly delineated links between evidence and recommendations and also because of the robust evidence base published over the last decade. An important change in ATP III is the expansion of the high-risk category to include patients without evident vascular disease, but with a level of risk equivalent to those patients with established CHD. This group termed "coronary heart disease equivalents" now includes patients with diabetes, and those with a 10-year absolute risk of over 20 percent for CHD events. With the ATP III report, the Framingham risk score is formally introduced into the guideline process. The scoring system allows for easy calculation of the absolute risk for an individual of having a "hard" CHD event (myocardial infarction, or CHD death). The report also discusses in detail concepts of lifetime or long-term risk. ATP III has broadened recommendations for lifestyle change termed "therapeutic lifestyle change (TLC)," and eliminated the step 1 and step 2 diet approach. Finally, the report details established approaches to improve adherence and provides patients and clinicians with a set of implementation tools to enhance use of the guidelines and compliance with the guidelines' recommendations. It is hoped that by improved understanding, recognition of a firm evidence base, and education through multiple channels, that adherence with the new ATP III guidelines will improve the care of our population by more effectively targeting lipid factors that lead to the development and progression of atherosclerotic cardiovascular disease.

RESUMEN

The worldwide spread of the coronary heart disease (CHD) epidemic is, in part, related to unfavorable changes in dietary patterns in the developing world. Much has been learned about optimal nutrition for the prevention of CHD. These lessons can, and should, be applied to countries where the burden of CHD is rapidly increasing, in order to help slow the progression of the CHD epidemic, to save many lives, and to prevent considerable disability worldwide.
