Introduction: Black Americans have higher rates of cardiovascular disease (CVD) mortality compared with whites. Differences in sociodemographic, psychosocial, CVD, and other risk factors may explain increased mortality risk. Methods: We analyzed data from 29,015 REasons for Geographic and Racial Differences in Stroke study participants to determine factors that may explain the higher hazard ratio for CVD and non-CVD mortality in blacks compared with whites. Cause of death was adjudicated by trained investigators. Within age-sex sub-groups, we used Cox proportional hazards regression with progressive adjustment to estimate black:white hazard ratios. Results: Overall, 41.0% of participants were black, and 54.9% were women. Over a mean follow-up of 7.1 years (maximum 12.3 years), 5,299 participants died (1,797 CVD and 3,502 non-CVD deaths). Among participants < 65 years of age, the age and region adjusted black:white hazard ratio for CVD mortality was 2.28 (95% CI: 1.68-3.10) and 2.32 (95% CI: 1.80-3.00) for women and men, respectively, and for participants ≥ 65 was 1.54 (95% CI: 1.30-1.82) and 1.35 (95% CI: 1.16-1.57) for women and men, respectively ( Table ). The higher black:white hazard ratios for CVD mortality were no longer statistically significant after multivariable adjustment, with the largest attenuation occurring with sociodemographic and CVD risk factor adjustment. Among participants < 65 years of age, the age and region adjusted black:white hazard ratios for non-CVD mortality were 1.51 (95% CI: 1.24-1.85) and 1.76 (95% CI: 1.46-2.13) for women and men, respectively, and for participants ≥ 65 was 1.12 (95% CI: 1.00-1.26) and 1.34 (95% CI: 1.20-1.49) for women and men, respectively. The higher black:white hazard ratios for non-CVD mortality were attenuated after adjustment for sociodemographics. Conclusions: Black:white differences are larger for CVD than non-CVD causes of death. The increased CVD mortality for blacks compared with whites is primarily explained by sociodemographic and CVD risk factors.

Background: Increased attention has been given to pulse pressure (PP) as a potential independent risk factor of cardiovascular disease. We examined the relationship between PP and incident acute coronary heart disease (CHD). Methods: We used data from the REasons for Geographic And Racial Differences in Stroke (REGARDS) national cohort study of 30,239 black and white participants aged 45 years or older and enrolled between 2003 and 2007. Baseline data included a 45-minute interview and in-home visit during which blood pressure was assessed and recorded as the average of two measurements obtained after a 5 minute seated rest. PP (SBP-DBP) was classified into 4 groups (<45, 45-54, 54.1-64, >64.1 mmHg). Telephone follow-up occurred every six months for self or proxy-reported suspected events, triggering medical record retrieval and adjudication by experts. Cox-proportional hazards models examined the association of incident CHD with PP groups, adjusting for socio-demographic and clinical risk factors. Results: This analysis included 22,909 participants free of CHD at baseline, with mean age 64.7±9.4 years; 40.4%were black, 44.6% were male and they experienced a total of 515 incident CHD events over a mean 3.4 yrs of follow-up (maximum 6 years). In unadjusted analyses, compared with PP<45 mmHg, each higher PP group had incrementally higher hazard ratios (HR) for incident CHD (HR 1.28 {95% CI 1.02-1.60}, 2.05 {1.63-2.56}, 3.82 {3.08-4.74}, p<0.001 for linear trend). This relationship persisted after fully adjusting including SBP for the highest PP group (HR 0.96 {0.75-1.21}, 1.12 {0.86-1.46}, 1.51 {1.09-2.10}, p trend <0.0001). Conclusions: High PP was associated with incident CHD, even when accounting for SBP and numerous other CVD risk factors.

Objectives. To determine factors that explain the higher Black:White cardiovascular disease (CVD) mortality rates among US adults. Methods. We analyzed data from the Reasons for Geographic and Racial Differences in Stroke study from 2003 to 2017 to estimate Black:White hazard ratios (HRs) for CVD mortality within subgroups younger than 65 years and aged 65 years or older. Results. Among 29 054 participants, 41.0% who were Black and 54.9% who were women, 1549 CVD deaths occurred. Among participants younger than 65 years, the demographic-adjusted Black:White CVD mortality HR was 2.23 (95% confidence interval [CI] = 1.87, 2.65) and 1.21 (95% CI = 1.00, 1.47) after full adjustment. Among participants aged 65 years or older, the demographic-adjusted Black:White CVD mortality HR was 1.58 (95% CI = 1.39, 1.79) and 1.12 (95% CI = 0.97, 1.29) after full adjustment. When we used mediation analysis, socioeconomic status explained 21.2% (95% CI = 13.6%, 31.4%) and 38.0% (95% CI = 20.9%, 61.7%) of the Black:White CVD mortality risk difference among participants younger than 65 years and aged 65 years or older, respectively. CVD risk factors explained 56.6% (95% CI = 42.0%, 77.2%) and 41.3% (95% CI = 22.9%, 65.3%) of the Black:White CVD mortality difference for participants younger than 65 years and aged 65 years or older, respectively. Conclusions. The higher Black:White CVD mortality risk is primarily explained by racial differences in socioeconomic status and CVD risk factors.

Abstract Objectives Evidence suggests low vitamin K status may be associated with an increased cardiovascular disease (CVD) risk in people with CVD risk factors. The objective of this study was to summarize the association between vitamin K status and CVD, overall and according to baseline CVD risk, by conducting a participant-level meta-analysis using data from the Framingham Offspring Study, the Health, Aging, and Body Composition Study (Health ABC), and the Multi-ethnic Study of Atherosclerosis (MESA). Methods Circulating phylloquinone (vitamin K1), measured from baseline fasting blood samples, was categorized as ≤0.5 nM, >0.5 - ≤1.0 nM and >1.0 nM. CVD was defined as confirmed ischemic heart disease, angina, resuscitated cardiac arrest, fatal or non-fatal myocardial infarction or stroke. Multivariable Cox proportional hazards models were used to evaluate the association between circulating phylloquinone and incident CVD overall and stratified according to baseline CVD risk factors. Results Among the 3622 participants (mean (SD) baseline age 65 (11), 45% men, 65% white), there were 785 CVD events over a median of 13.0 years. Overall the risk for CVD did not differ significantly according to circulating phylloquinone categories [HR(95%CI) for CVD, compared to plasma phylloquinone >1.0 nM: ≤0.5 nM = 1.15 (0.96–1.38); >0.5 - ≤1.0 nM = 0.99 (0.84–1.18)]. However, lower circulating phylloquinone was associated with higher incident CVD risk in those with diabetes, with a normal BMI, and in women (Table). Conclusions Overall, we did not detect any significant differences in CVD risk across circulating phylloquinone categories in community-dwelling adults. However, low circulating phylloquinone was associated with a higher CVD risk among certain sub-groups, but additional studies are needed to clarify if improving vitamin K status will benefit the cardiovascular health of certain segments of the population.

Abstract Background Although social capital has been shown to be one of the important social determinants of health, the association between social trust and the risk of cardiovascular disease (CVD) is not clear yet. We aimed to investigate the association of social trust with CVD risk using a large Korean population. Methods The study data was derived from the Korean National Health Insurance Service database. Community-level social trust was determined from the Koran Community Health Survey. The study population consisted of 2,156,829 participations. According to social trust index measured in the area of residence during 2011, participants were followed-up from 1 January 2012 to 31 December 2016. Multivariate Cox proportional hazards regression was used to determine the adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) for CVD risk according to quintiles of social trust. Results Compared to participants with the lowest quintile of social trust, those within the highest quintile had lower risk for CVD (aHR 0.91, 95% CI = 0.89 to 0.93), CHD (aHR 0.92, 95% CI = 0.89 to 0.95), and stroke (aHR 0.90, 95% CI = 0.87 to 0.93). The risk-reducing association of high social trust on CVD risk was preserved after additional adjustments for lifestyle behaviors including smoking, alcohol intake, and physical activity. Conclusion Higher social trust was associated with reduced risk of CVD even after considering lifestyle behaviors. Social trust in a community level is an important determinant of CVD and enhancing social trust may lead to reduced risk of CVD.

Background: The risk of cardiovascular mortality is high among adults with end-stage renal disease (ESRD) undergoing hemodialysis. Waist-to-hip ratio (WHR), a metric of abdominal adiposity, is a predictor of cardiovascular disease (CVD) and mortality in the general population; however, no studies have examined the association with CVD mortality, particularly sudden cardiac death (SCD), in incident hemodialysis. Methods: Among 379 participants incident (< 6 months) to hemodialysis enrolled in the Predictors of Arrhythmic and Cardiovascular Risk in ESRD study, we evaluated associations between WHR and risk of CVD mortality, SCD, and non-CVD mortality in Cox proportional hazards regression models. Results: At study enrollment, mean age was 55 years with 41% females, 73% African Americans, and 57% diabetics. Mean body mass index was 29.3 kg/m2, and mean WHR was 0.95. During a median follow-up time of 2.5 years, there were 35 CVD deaths, 15 SCDs, and 48 non-CVD deaths. Every 0.1 increase in WHR was associated with higher risk (hazard ratio [95% CI]) of CVD mortality (1.75 [1.06–2.86]) and SCD (2.45 [1.20–5.02]), but not non-CVD mortality (0.93 [0.59–1.45]), independently of demographics, body mass index, comorbidities, inflammation, and traditional CVD risk factors. Conclusions: WHR is significantly associated with CVD mortality including SCD, independently of other CVD risk factors in incident hemodialysis. This simple, easily obtained bedside metric may be useful in dialysis patients for CVD risk stratification.

Background Cardiovascular disease (CVD) in women has unique features, including associations with reproductive factors that are incompletely understood. Vasomotor symptoms (VMS), the classic menopausal symptom, are linked to CVD risk factors and subclinical CVD. Evidence linking VMS to CVD events is limited. We tested whether frequent and/or persistent VMS were associated with increased risk for fatal and nonfatal CVD events in SWAN (Study of Women’s Health Across the Nation). Methods and Results A total of 3083 women, aged 42 to 52 years at baseline, underwent up to 16 in‐person visits over 22 years. Assessments included questionnaires on VMS frequency (0, 1–5, or ≥6 days/2 weeks), physical measures, phlebotomy, and reported CVD events (myocardial infarction, stroke, heart failure, and revascularization). A subset of events was adjudicated via medical record. Death certificates were obtained. Relationships between baseline VMS or persistent VMS over the follow‐up (proportion of visits with frequent VMS) with combined incident nonfatal and fatal CVD were tested in Cox proportional hazards models adjusted for demographics, medication use, and CVD risk factors. Participants experienced 231 CVD events over the follow‐up. Women with frequent baseline VMS had an elevated risk of subsequent CVD events (relative to no VMS; ≥6 days: hazard ratio [HR] [95% CI], 1.51 [1.05–2.17], P =0.03; 1–5 days: HR [95% CI], 1.02 [0.75–1.39], P =0.89, multivariable). Women with frequent VMS that persisted over time also had an increased CVD event risk (>33% versus ≤33% of visits: HR [95% CI], 1.77 [1.33–2.35], P <0.0001, multivariable). Conclusions Frequent and persistent VMS were associated with increased risk of later CVD events. VMS may represent a novel female‐specific CVD risk factor.

AbstractThe purpose is to investigate the added prognostic value of coronary artery calcium (CAC), thoracic aortic calcium (TAC), and heart valve calcium scores for prediction of a combined endpoint of recurrent major cardiovascular events and cardiovascular interventions (MACE +) in patients with established cardiovascular disease (CVD). In total, 567 patients with established CVD enrolled in a substudy of the UCC-SMART cohort, entailing cardiovascular CT imaging and calcium scoring, were studied. Five Cox proportional hazards models for prediction of 4-year risk of MACE + were developed; traditional CVD risk predictors only (model I), with addition of CAC (model II), TAC (model III), heart valve calcium (model IV), and all calcium scores (model V). Bootstrapping was performed to account for optimism. During a median follow-up of 3.43 years (IQR 2.28–4.74) 77 events occurred (MACE+). Calibration of predicted versus observed 4-year risk for model I without calcium scores was good, and the c-statistic was 0.65 (95%CI 0.59–0.72). Calibration for models II–V was similar to model I, and c-statistics were 0.67, 0.65, 0.65, and 0.68 for model II, III, IV, and V, respectively. NRIs showed improvement in risk classification by model II (NRI 15.24% (95%CI 0.59–29.39)) and model V (NRI 20.00% (95%CI 5.59–34.92)), but no improvement for models III and IV. In patients with established CVD, addition of the CAC score improved performance of a risk prediction model with classical risk factors for the prediction of the combined endpoint MACE+ . Addition of the TAC or heart valve score did not improve risk predictions.

Purpose Findings on the association between risk of cardiovascular disease (CVD) and the duration and type of androgen-deprivation therapy (ADT) in men with prostate cancer (PCa) are inconsistent. Methods By using data on filled drug prescriptions in Swedish national health care registers, we investigated the risk of CVD in a cohort of 41,362 men with PCa on ADT compared with an age-matched, PCa-free comparison cohort (n = 187,785) by use of multivariable Cox proportional hazards regression models. Results From 2006 to 2012, 10,656 men were on antiandrogens (AA), 26,959 were on gonadotropin-releasing hormone (GnRH) agonists, and 3,747 underwent surgical orchiectomy. CVD risk was increased in men on GnRH agonists compared with the comparison cohort (hazard ratio [HR] of incident CVD, 1.21; 95% CI, 1.18 to 1.25; and orchiectomy: HR, 1.16; 95% CI, 1.08 to 1.25). Men with PCa on AA were at decreased risk (HR of incident CVD, 0.87; 95% CI, 0.82 to 0.91). CVD risk was highest during the first 6 months of ADT in men who experienced two or more cardiovascular events before therapy, with an HR of CVD during the first 6 months of GnRH agonist therapy of 1.91 (95% CI, 1.66 to 2.20), an HR of CVD with AA of 1.60 (95% CI, 1.24 to 2.06), and an HR of CVD with orchiectomy of 1.79 (95% CI, 1.16 to 2.76) versus the comparison cohort. Conclusion Our results support that there should be a solid indication for ADT in men with PCa so that benefit outweighs potential harm; this is of particular importance among men with a recent history of CVD.
