RESUMO

BACKGROUND: High awareness that cardiovascular disease is the leading cause of death (LCOD) among women is critical to prevention. This study evaluated longitudinal trends in this awareness among women. METHODS AND RESULTS: Online surveys of US women (≥25 years of age) were conducted in January 2009 and January 2019. Data were weighted to the US population distribution of sociodemographic characteristics. Multivariable logistic regression was used to evaluate knowledge of the LCOD. In 2009, awareness of heart disease as the LCOD was 65%, decreasing to 44% in 2019. In 2019, awareness was greater with older age and increasing education and lower among non-White women and women with hypertension. The 10-year awareness decline was observed in all races/ethnicities and ages except women ≥65 years of age. The greatest declines were among Hispanic women (odds ratio of awareness comparing 2019 to 2009, 0.14 [95% CI, 0.07-0.28]), non-Hispanic Black women (odds ratio, 0.31 [95% CI, 0.19-0.49]), and 25- to 34-year-olds (odds ratio, 0.19 [95% CI, 0.10-0.34]). In 2019, women were more likely than in 2009 to incorrectly identify breast cancer as the LCOD (odds ratio, 2.59 [95% CI, 1.86-3.67]), an association that was greater in younger women. Awareness of heart attack symptoms also declined. CONCLUSIONS: Awareness that heart disease is the LCOD among women declined from 2009 to 2019, particularly among Hispanic and non-Hispanic Black women and in younger women (in whom primordial/primary prevention may be most effective). An urgent redoubling of efforts by organizations interested in women's health is required to reverse these trends.

RESUMO

BACKGROUND: The purpose of this study was to evaluate trends in awareness of cardiovascular disease (CVD) risk among women between 1997 and 2012 by racial/ethnic and age groups, as well as knowledge of CVD symptoms and preventive behaviors/barriers. METHODS AND RESULTS: A study of awareness of CVD was conducted by the American Heart Association in 2012 among US women >25 years of age identified through random-digit dialing (n=1205) and Harris Poll Online (n=1227), similar to prior American Heart Association national surveys. Standardized questions on awareness were given to all women; additional questions about preventive behaviors/barriers were given online. Data were weighted, and results were compared with triennial surveys since 1997. Between 1997 and 2012, the rate of awareness of CVD as the leading cause of death nearly doubled (56% versus 30%; P<0.001). The rate of awareness among black and Hispanic women in 2012 (36% and 34%, respectively) was similar to that of white women in 1997 (33%). In 1997, women were more likely to cite cancer than CVD as the leading killer (35% versus 30%), but in 2012, the trend reversed (24% versus 56%). Awareness of atypical symptoms of CVD has improved since 1997 but remains low. The most common reasons why women took preventive action were to improve health and to feel better, not to live longer. CONCLUSIONS: Awareness of CVD among women has improved in the past 15 years, but a significant racial/ethnic minority gap persists. Continued effort is needed to reach at-risk populations. These data should inform public health campaigns to focus on evidenced-based strategies to prevent CVD and to help target messages that resonate and motivate women to take action.

RESUMO

BACKGROUND AND PURPOSE: Recognition of stroke warning signs may reduce treatment delays. The purpose of this study was to evaluate contemporary knowledge of stroke warning signs and knowledge to call 9-1-1, among a nationally representative sample of women, overall and by race/ethnic group. METHODS: A study of cardiovascular disease awareness was conducted by the American Heart Association in 2012 among English-speaking US women ≥25 years identified through random-digit dialing (n=1205; 54% white, 17% black, 17% Hispanic, and 12% other). Knowledge of stroke warning signs, and what to do first if experiencing stroke warning signs, was assessed by standardized open-ended questions. RESULTS: Half of women surveyed (51%) identified sudden weakness/numbness of face/limb on one side as a stroke warning sign; this did not vary by race/ethnic group. Loss of/trouble talking/understanding speech was identified by 44% of women, more frequently among white versus Hispanic women (48% versus 36%; P<0.05). Fewer than 1 in 4 women identified sudden severe headache (23%), unexplained dizziness (20%), or sudden dimness/loss of vision (18%) as warning signs, and 1 in 5 (20%) did not know 1 stroke warning sign. The majority of women said that they would call 9-1-1 first if they thought they were experiencing signs of a stroke (84%), and this did not vary among black (86%), Hispanic (79%), or white/other (85%) women. CONCLUSIONS: Knowledge of stroke warning signs was low among a nationally representative sample of women, especially among Hispanics. In contrast, knowledge to call 9-1-1 when experiencing signs of stroke was high.

RESUMO

BACKGROUND: Family members of patients with coronary artery disease (CAD) have higher risk of vascular events. We conducted a trial to determine if a family heart-health intervention could reduce their risk of CAD. METHODS: We assessed coronary risk factors and randomized 426 family members of patients with CAD to a family heart-health intervention (n = 211) or control (n = 215). The intervention included feedback about risk factors, assistance with goal setting and counselling from health educators for 12 months. Reports were sent to the primary care physicians of patients whose lipid levels and blood pressure exceeded threshold values. All participants received printed materials about smoking cessation, healthy eating, weight management and physical activity; the control group received only these materials. The main outcomes (ratio of total cholesterol to high-density lipoprotein [HDL] cholesterol; physical activity; fruit and vegetable consumption) were assessed at 3 and 12 months. We examined group and time effects using mixed models analyses with the baseline values as covariates. The secondary outcomes were plasma lipid levels (total cholesterol, low-density lipoprotein cholesterol, HDL cholesterol and triglycerides); glucose level; blood pressure; smoking status; waist circumference; body mass index; and the use of blood pressure, lipid-lowering and smoking cessation medications. RESULTS: We found no effect of the intervention on the ratio of total cholesterol to HDL cholesterol. However, participants in the intervention group reported consuming more fruit and vegetables (1.2 servings per day more after 3 mo and 0.8 servings at 12 mo; p < 0.001). There was a significant group by time interaction for physical activity (p = 0.03). At 3 months, those in the intervention group reported 65.8 more minutes of physical activity per week (95% confidence interval [CI] 47.0-84.7 min). At 12 months, participants in the intervention group reported 23.9 more minutes each week (95% CI 3.9-44.0 min). INTERPRETATION: A health educator-led heart-health intervention did not improve the ratio of total cholesterol to HDL cholesterol but did increase reported physical activity and fruit and vegetable consumption among family members of patients with CAD. Hospitalization of a spouse, sibling or parent is an opportunity to improve cardiovascular health among other family members. TRIAL REGISTRATION: clinicaltrials.gov, no NCT00552591.

RESUMO

BACKGROUND: Patients who have undergone cardiac surgery, especially those with greater comorbidities, may be cared for by family members or paid aides. OBJECTIVE: The purpose of this study was to evaluate the association between having a caregiver among patients who underwent cardiac surgery and clinical outcomes at 1 year. We hypothesized that patients with a caregiver would have longer lengths of stay and higher rehospitalization or death rates 1 year after surgery. METHODS: We studied 665 patients consecutively admitted for cardiac surgery as part of the Family Cardiac Caregiver Investigation To Evaluate Outcomes sponsored by the National Heart, Lung, and Blood Institute. The participants (mean age, 65 years; women, 35%; racial/ethnic minorities, 21%) completed an interviewer-assisted questionnaire to determine caregiver status. Outcomes were documented by a hospital-based information system; demographics/comorbidities, by electronic records. Associations between having a caregiver and outcomes were evaluated by logistic regression, adjusted for demographic and comorbid conditions. RESULTS: At baseline, 28% of the patients (n = 183) had a caregiver (8%, paid; 20%, informal only). Having a caregiver was associated with longer (>7 days) postoperative length of stay in univariate analysis among the patients with paid (odds ratio [OR], 3.00; 95% confidence interval [CI], 1.57-5.74) or informal (OR, 1.55; 95% CI, 1.04-2.31) caregivers versus none; the association remained significant for the patients with paid (OR, 2.13; 95% CI, 1.00-4.55) but not with informal (OR, 1.12; 95% CI, 0.70-1.80) caregivers after adjustment. Having a paid caregiver was significantly associated with rehospitalization/death at 1 year in univariate analysis (OR, 2.09; 95% CI, 1.18-3.69); having an informal caregiver was not (OR, 1.39; 95% CI, 0.94-2.06). Increased odds of rehospitalization/death associated with having a paid caregiver attenuated after adjustment (OR, 1.39; 95% CI, 0.74-2.62). CONCLUSIONS: The patients who underwent cardiac surgery who had a paid caregiver had a significantly longer length of stay independent of comorbidity. The increased risk of rehospitalization/death associated with having a paid caregiver was explained by demographics and comorbidity. These data suggest that caregiver status assessment may be a simple method to identify cardiac surgery patients at increased risk for adverse clinical outcomes.

RESUMO

BACKGROUND: The risk of incident cardiovascular disease (CVD) has been shown to be greater among diabetic women than men, but gender differences in clinical outcomes among diabetic patients hospitalized with CVD are not established. We aimed to determine if hemoglobin A1c (HbA1c) was associated with 30-day and 1-year CVD rehospitalization and total mortality among diabetic patients hospitalized for CVD, overall and by gender. METHODS: This was a prospective analysis of diabetic patients hospitalized for CVD, enrolled in an National Heart, Lung and Blood Institute-sponsored observational clinical outcomes study (N = 902, 39% female, 53% racial/ethnic minority, mean age 67 ± 12 years). Laboratory, rehospitalization, and mortality data were determined by hospital-based electronic medical record. Poor glycemic control was defined as HbA1c ≥7%. The association between HbA1c and clinical outcomes was evaluated using logistic regression; gender modification was evaluated by interaction terms and stratified models. RESULTS: Hemoglobin A1c ≥7% prevalence was 63% (n = 566) and was similar by gender. Hemoglobin A1c ≥7% vs <7% was associated with increased 30-day CVD rehospitalization in univariate (odds ratio [OR] = 1.63, 95% CI 1.05-2.54) and multivariable-adjusted models (OR 1.74, 95% CI 1.06-2.84). There was an interaction between glycemic control and gender for 30-day CVD rehospitalization risk (P = .005). In stratified univariate models, the association was significant among women (OR 4.83, 95% CI 1.84-12.71) but not among men (OR 1.02, 95% CI 0.60-1.71). The multivariate-adjusted risk for HbA1c ≥7% versus <7% among women was 8.50 (95% CI 2.31-31.27) and 1.02 (95% CI 0.57-1.80) for men. A trend toward increased 30-day/1-year mortality risk was observed for HbA1c <6% vs ≥6% for men and women. CONCLUSIONS: Risk of 30-day CVD rehospitalization was 8.5-fold higher among diabetic women hospitalized for CVD with HbA1c ≥7% vs <7%; no association was observed among men. A trend for increased 30-day/1-year mortality risk with HbA1c <6% deserves further study.

RESUMO

BACKGROUND: Medication non-adherence is a significant contributor to suboptimal control of blood pressure and lipids. PURPOSE: This study determined if having a paid and/or family caregiver was associated with medication adherence in patients hospitalized for cardiovascular disease. METHODS: Consecutive patients admitted to the cardiovascular service at a university medical center who completed a standardized questionnaire about medication adherence and caregiving (paid/professional or family member/friend) were included in this analysis (N = 1,432; 63 % white; 63%male). RESULTS: Among cardiac patients, 39 % reported being prescribed ≥ 7 different medications, and one in four reported being non-adherent to their medication(s). Participants who reported having/planning to have a paid caregiver were 40 % less likely to be non-adherent to their medications compared to their counterparts. The association remained significant after adjustment for demographic confounders and comorbid conditions (OR = 0.49; 95 %CI = 0.29-0.82). CONCLUSION: Cardiac patients with a paid caregiver were half as likely to be non-adherent to medications as those without caregivers.

RESUMO

BACKGROUND: Tibolone has estrogenic, progestogenic, and androgenic effects. Although tibolone prevents bone loss, its effects on fractures, breast cancer, and cardiovascular disease are uncertain. METHODS: In this randomized study, we assigned 4538 women, who were between the ages of 60 and 85 years and had a bone mineral density T score of -2.5 or less at the hip or spine or a T score of -2.0 or less and radiologic evidence of a vertebral fracture, to receive once-daily tibolone (at a dose of 1.25 mg) or placebo. Annual spine radiographs were used to assess for vertebral fracture. Rates of cardiovascular events and breast cancer were adjudicated by expert panels. RESULTS: During a median of 34 months of treatment, the tibolone group, as compared with the placebo group, had a decreased risk of vertebral fracture, with 70 cases versus 126 cases per 1000 person-years (relative hazard, 0.55; 95% confidence interval [CI], 0.41 to 0.74; P<0.001), and a decreased risk of nonvertebral fracture, with 122 cases versus 166 cases per 1000 person-years (relative hazard, 0.74; 95% CI, 0.58 to 0.93; P=0.01). The tibolone group also had a decreased risk of invasive breast cancer (relative hazard, 0.32; 95% CI, 0.13 to 0.80; P=0.02) and colon cancer (relative hazard, 0.31; 95% CI, 0.10 to 0.96; P=0.04). However, the tibolone group had an increased risk of stroke (relative hazard, 2.19; 95% CI, 1.14 to 4.23; P=0.02), for which the study was stopped in February 2006 at the recommendation of the data and safety monitoring board. There were no significant differences in the risk of either coronary heart disease or venous thromboembolism between the two groups. CONCLUSIONS: Tibolone reduced the risk of fracture and breast cancer and possibly colon cancer but increased the risk of stroke in older women with osteoporosis.

RESUMO

BACKGROUND AND OBJECTIVES: Cardiac caregivers may represent a novel low-cost strategy to improve patient adherence to medical follow-up and guidelines and, ultimately, patient outcomes. Prior work on caregiving has been conducted primarily in mental health and cancer research; few data have systematically evaluated caregivers of cardiac patients. The purpose of this study was to evaluate the patterns of caregiving and characteristics of caregivers among hospitalized patients with cardiovascular disease (CVD) to assess disparities in caregiver burden and to determine the potential for caregivers to impact clinical outcomes. SUBJECTS AND METHODS: Consecutive patients admitted to the cardiovascular service line at a university medical center during an 11-month period were included in the Family Cardiac Caregiver Investigation To Evaluate Outcomes (FIT-O) study. Patients (n=4500; 59% white, 62% male, 93% participation rate) completed a standardized interviewer-assisted questionnaire in English or Spanish regarding assistance with medical care, daily activities, and medications in the past year and plans for posthospitalization. In univariate and multiple variable analyses, caregivers were categorized as either paid/professional (eg, nurse/home aide) or nonpaid (eg, family member/friend). RESULTS AND CONCLUSIONS: Among CVD patients, 13% planned to have a paid caregiver and 51% a nonpaid caregiver at discharge. Planned paid caregiving was more prevalent among racial/ethnic minority versus white patients (odds ratio, 1.5; 95% confidence interval, 1.2-1.8); planned nonpaid caregiving prevalence did not differ by race/ethnicity. Most nonpaid caregivers were female (78%). Patients who had nonpaid caregivers in the year prior to hospitalization (28%) reported grocery shopping/meal preparation (32%), transport to/arranging doctor visits (30%), and medication adherence/medical needs (25%) as top tasks caregivers assisted with. Following hospitalization, a majority of patients expect nonpaid caregivers, primarily women, to assist with tasks that have the potential to improve CVD outcomes such as medical follow-up, medication adherence, and nutrition, suggesting that these are important targets for caregiver education.

RESUMO

BACKGROUND: Informal caregivers of people with dementia provide the majority of health-based care to people with dementia. Providing this care requires knowledge and access to resources, which caregivers often do not receive. We set out to evaluate the effect of online educational tools on informal caregiver self-efficacy, quality of life, burden/stress, depression, and anxiety, and to identify effective processes for online educational tool development. METHODS: We conducted a scoping review of articles on online educational interventions for informal caregivers of people with dementia searching CINAHL, MEDLINE, EMBASE, and PubMed from 1990 to March 2018, with an updated search conducted in 2020. The identified articles were screened and the data were charted. RESULTS: 33 articles that reported on 24 interventions were included. There is some evidence that online interventions improve caregiver-related outcomes such as self-efficacy, depression, dementia knowledge, and quality of life; and decrease caregiver burden. Common findings across the studies included the need for tailored, stage-specific information applicable to the caregiver's situation and the use of psychosocial techniques to develop the knowledge components of the interventions. CONCLUSION: We demonstrate the importance of having caregivers and health-care professionals involved at all stages of tool conceptualization and development. Online tools should be evaluated with robust trials that focus on how increased knowledge and development approaches affect caregiver-related outcomes.

RESUMO

The Go Red for Women movement was initiated by the American Heart Association (AHA) in the early 2000s to raise awareness concerning cardiovascular disease (CVD) risk in women. In 2016, the AHA funded 5 research centers across the United States to advance our knowledge of the risks and presentation of CVD that are specific to women. This report highlights the findings of the centers, showing how insufficient sleep, sedentariness, and pregnancy-related complications may increase CVD risk in women, as well as presentation and factors associated with myocardial infarction with nonobstructive coronary arteries and heart failure with preserved ejection fraction in women. These projects were augmented by collaborative ancillary studies assessing the relationships between various lifestyle behaviors, including nightly fasting duration, mindfulness, and behavioral and anthropometric risk factors and CVD risk, as well as metabolomic profiling of heart failure with preserved ejection fraction in women. The Go Red for Women Strategically Focused Research Network enhanced the evidence base related to heart disease in women, promoting awareness of the female-specific factors that influence CVD.

RESUMO

BACKGROUND: The Raloxifene Use for The Heart (RUTH) trial showed that raloxifene, a selective estrogen receptor modulator, had no overall effect on the incidence of coronary events in women with established coronary heart disease or coronary heart disease risk factors. We provide detailed results of the effect of raloxifene on coronary outcomes over time and for 24 subgroups (17 predefined, 7 post hoc). METHODS AND RESULTS: Postmenopausal women (n=10 101; mean age, 67 years) were randomized to raloxifene 60 mg/d or placebo for a median of 5.6 years. Coronary outcomes were assessed by treatment group in women with coronary heart disease risk factors and those with established coronary heart disease. Raloxifene had no effect on the incidence of coronary events in any subgroup except in the case of a post hoc age subgroup analysis using age categories defined in the Women's Health Initiative randomized trials. The effect of raloxifene on the incidence of coronary events differed significantly by age (interaction P=0.0118). The incidence of coronary events in women <60 years of age was significantly lower in those assigned raloxifene (50 events) compared with placebo (84 events; hazard ratio, 0.59; 95% confidence interval, 0.41 to 0.83; P=0.003; absolute risk reduction, 36 per 1000 women treated for 1 year). No difference was found between treatment groups in the incidence of coronary events in women > or =60 and <70 or > or =70 years of age. CONCLUSIONS: In postmenopausal women at increased risk of coronary events, the overall lack of benefit of raloxifene was similar across the prespecified subgroups.

RESUMO

BACKGROUND: Inhibition of cholesteryl ester transfer protein (CETP) has been shown to have a substantial effect on plasma lipoprotein levels. We investigated whether torcetrapib, a potent CETP inhibitor, might reduce major cardiovascular events. The trial was terminated prematurely because of an increased risk of death and cardiac events in patients receiving torcetrapib. METHODS: We conducted a randomized, double-blind study involving 15,067 patients at high cardiovascular risk. The patients received either torcetrapib plus atorvastatin or atorvastatin alone. The primary outcome was the time to the first major cardiovascular event, which was defined as death from coronary heart disease, nonfatal myocardial infarction, stroke, or hospitalization for unstable angina. RESULTS: At 12 months in patients who received torcetrapib, there was an increase of 72.1% in high-density lipoprotein cholesterol and a decrease of 24.9% in low-density lipoprotein cholesterol, as compared with baseline (P<0.001 for both comparisons), in addition to an increase of 5.4 mm Hg in systolic blood pressure, a decrease in serum potassium, and increases in serum sodium, bicarbonate, and aldosterone (P<0.001 for all comparisons). There was also an increased risk of cardiovascular events (hazard ratio, 1.25; 95% confidence interval [CI], 1.09 to 1.44; P=0.001) and death from any cause (hazard ratio, 1.58; 95% CI, 1.14 to 2.19; P=0.006). Post hoc analyses showed an increased risk of death in patients treated with torcetrapib whose reduction in potassium or increase in bicarbonate was greater than the median change. CONCLUSIONS: Torcetrapib therapy resulted in an increased risk of mortality and morbidity of unknown mechanism. Although there was evidence of an off-target effect of torcetrapib, we cannot rule out adverse effects related to CETP inhibition. (ClinicalTrials.gov number, NCT00134264 [ClinicalTrials.gov].).

RESUMO

Blood pressure and cholesterol reduction have proven effective to reduce cardiovascular disease (CVD) risk, yet adherence to medical therapy is suboptimal and contributing factors to non-adherence are not well-established. The purpose of this study was to determine the prevalence and predictors of non-adherence to blood pressure and cholesterol-lowering medications in individuals who participated in an NHLBI-sponsored evaluation of a hospital-based screening and outreach program for high-risk employees and the community. This was a cross-sectional study of 371 adults (mean age 60 years, 57% female, 60% non-white) who were eligible to participate if they were men >40 years, women >50 years, or had established CVD or CVD-risk equivalent. Each participant received a comprehensive standardized CVD screening evaluation; medication non-adherence was defined as missing any pills for high blood pressure or abnormal cholesterol in the past week. Associations between participant demographics, lifestyle and psychosocial risk factors, and non-adherence were assessed using logistic regression to adjust for confounders. The prevalence of taking medication for high blood pressure or abnormal cholesterol in the study population was 48% and 38%, respectively. Among those participants, 14% reported missing high blood pressure pills and 23% reported missing cholesterol pills in the past week. Significant (p<0.05) univariate predictors of non-adherence to blood pressure medication were smoking, depression, feeling sad or blue for 2 weeks or more, and eating fast food ≥2 times per week. In a multivariable regression model adjusted for confounders, participants who reported missing any blood pressure pills in the past week were 6.6 times more likely to have uncontrolled hypertension (≥140/90 mmHg) compared to those who were adherent (95% CI = 2.1-20.2). Age <65 years and eating outside the home ≥2 times per week were significantly associated with non-adherence to cholesterol medication even after adjusting for measured confounders. Non-adherence to preventive medications was associated with poor blood pressure control and several lifestyle and psychosocial risk factors for CVD. This information may be clinically useful to help identify individuals who may be non-adherent to medical therapy and at increased CVD risk.

RESUMO

BACKGROUND AND OBJECTIVE: Recommendations for physical activity to lower risk of cardiovascular disease (CVD) are widely known but not often followed. The purpose of this study was to determine the demographic, lifestyle, and psychosocial variables that predict improved physical activity among participants in a CVD prevention lifestyle intervention trial. SUBJECTS AND METHODS: Adult family members (N = 501; 66% female; 36% nonwhite; mean age, 48 years) of cardiac patients were randomized to a 1-year special intervention that received education on physical activity or to a control intervention. Demographics, physical activity, stage of change, and CVD risk factors were measured systematically at baseline and 1 year (94% follow-up). Lipids were analyzed in a core laboratory. Linear regression models were adjusted for confounders. RESULTS: At baseline, 21% of participants reported exercising more than 3 d/wk, which did not differ by group assignment. The special intervention and control intervention experienced significant increases in physical activity at 1 year with mean physical activity days per week in the special intervention significantly greater than the control intervention (2.5 vs 2.0 d/wk, P = .03). Significant predictors of increased physical activity at 1 year were group assignment (P = .03), female sex (P = .04), nonminority status (P <.01), greater readiness to change (P <.01), and baseline measurements of lower body mass index (P <.01) and waist size (P <.01), greater diet adherence (P <.01), higher high-density lipoprotein cholesterol (P <.01), lower high-sensitivity C-reactive protein (P = .02), less depression (P <.01), and higher social support (P = .03). In multiple regression models, group assignment, female, and nonminority status remained independent predictors of higher physical activity levels at 1 year. CONCLUSION: Several predictors of improved physical activity levels at 1 year were documented among clinical trial participants. Racial/ethnic minorities and men were significantly less likely to make positive changes and may need more targeted efforts to improve physical activity levels.

RESUMO

Using behavioral self-regulation processes may facilitate exercise among older women with heart disease. Data from women in a heart disease-management program (n = 658, mean 73 years), was used to explore associations among exercise self-regulation components (i.e., choosing to improve exercise and observing, judging, and reacting to one's behavior) and exercise capacity. General linear models showed that choosing exercise predicted higher exercise self-regulation scores postprogram and 8 months later. In turn, these scores predicted greater improvements in exercise capacity concurrently and 8 months later. Interaction analyses revealed that the effect of self-regulation on exercise capacity was stronger among women who chose to work on exercise.

RESUMO

Management of residual and persistent cardiovascular disease (CVD) risk among statin-treated individuals has emerged as an important preventive strategy. The purpose of this article is to review the unique landscape of CVD in women and relevant prior prevention trials, and to discuss how the recent results of the Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention Trial (REDUCE-IT) might apply to the contemporary management of CVD risk among statin-treated women. Women have unique risk factors that may impact CVD and its prevention. Historically, women have been underrepresented in CVD trials, posing a challenge to development of clinical recommendations for women. Low-density lipoprotein cholesterol-targeting treatments have demonstrated CVD risk reduction, with comparable effects in both sexes. In contrast, triglyceride-lowering treatments (niacin, fenofibrate, and omega-3 fatty acids) have reported mixed findings for CVD risk reduction. Recent clinical trials of combination omega-3 fatty acids (docosahexaenoic acid/eicosapentaenoic acid [EPA]) have not found significant CVD risk reduction. The recently published REDUCE-IT study found that icosapent ethyl, an EPA-only omega-3 fatty acid, in combination with statins, significantly reduced CVD events in high-risk patients. The icosapent ethyl group had a significantly lower occurrence of the primary composite CVD endpoint (17.2%) than the placebo group (22.0%; hazard ratio 0.75; 95% confidence interval 0.68-0.83; p < 0.001). CVD risk reduction with icosapent ethyl treatment was comparable between women and men (p for interaction, 0.33). Data from REDUCE-IT suggest women benefit similarly to men with respect to icosapent ethyl, a novel therapy for prevention of CVD.
