The MMPI factor scales and risk of death in men during 45 years of follow-up: The Western Electric study.

We examined associations between personality traits measured in 1958 and both all-cause and cause-specific mortality assessed 45 years later in 2003. Participants were 1,862 middle-aged men employed by the Western Electric Company. Outcomes were days to death from all causes, coronary heart disease, stroke, cancer, and causes other than circulatory diseases, cancer, accidents/homicide/suicides, or injuries (other causes). Measures in 1958 included age, education, health behaviors, biomedical risk factors, and nine content factors identified in the Minnesota Multiphasic Personality Inventory (MMPI). Four content factors-neuroticism, cynicism, extraversion, and intellectual interests-were related to the five-factor model domains of neuroticism, agreeableness, extraversion, and openness, respectively. The remaining five-psychoticism, masculinity versus femininity, religious orthodoxy, somatic complaints, and inadequacy-corresponded to the five-factor model's facets and styles (combinations of two domains) or were unrelated to the five-factor model. In age-adjusted and fully adjusted models, cynicism was associated with greater all-cause and cancer mortality. In fully adjusted models, inadequacy was associated with lower all-cause mortality and lower mortality from other causes. In age-adjusted models, religious orthodoxy was associated with lower cancer mortality. Further analyses revealed that the association between cynicism and all-cause mortality waned over time. Exploratory analyses of death from any disease of the circulatory system revealed no further associations. These findings reveal the importance of cynicism (disagreeableness) as a mortality risk factor, show that associations between cynicism and all-cause mortality are limited to certain periods of the lifespan, and highlight the need to study personality styles or types, such as inadequacy, that involve high neuroticism, low extraversion, and low conscientiousness.

Association of Long-Term Risk Factor Levels With Carotid Atherosclerosis: The Chicago Healthy Aging Magnetic Resonance Imaging Plaque Study (CHAMPS).

BACKGROUND: Absence of cardiovascular risk factors (RF) in young adulthood is associated with a lower risk for cardiovascular disease. However, it is unclear if low RF burden in young adulthood decreases the quantitative burden and qualitative features of atherosclerosis. METHODS: Multi-contrast carotid magnetic resonance imaging was performed on 440 Chicago Healthy Aging Study participants in 2009 to 2011, whose RF (total cholesterol, blood pressure, diabetes mellitus, and smoking) were measured in 1967 to 1973. Participants were divided into 4 groups: low-risk (with total cholesterol <200 mg/dL and no treatment, blood pressure <120/80 mm Hg and no treatment, no smoking, and no diabetes mellitus), 0 high RF but some RF unfavorable (≥1 RF above low-risk threshold but below high-risk threshold), 1 high RF (total cholesterol ≥240 mg/dL or treated, blood pressure ≥140/90 or treated, diabetes mellitus, or smoking), and 2 or more high RF. Association of baseline RF status with carotid atherosclerosis (overall mean carotid wall thickness and lipid-rich necrotic core) at follow-up was assessed. RESULTS: Among 424 participants with evaluable carotid magnetic resonance images, the mean age was 32 years at baseline and 73 years at follow-up; 67% were male, 86% white, and 36% were low-risk at baseline. Two or more high RF status was associated with higher carotid wall thickness (0.99±0.11 mm) and lipid-rich necrotic core prevalence (30%), as compared with low-risk group (0.94±0.09 mm and 17%, respectively). Each increment in baseline RF status was associated with higher carotid wall thickness (ß-coefficient, 0.015; 95% CI, 0.004-0.026) and with higher lipid-rich necrotic core prevalence at older age (odds ratio, 1.26; 95% CI, 1.00-1.58) in models adjusted for baseline RF and demographics. CONCLUSIONS: RF status in young adulthood is associated with the burden and quality of carotid atherosclerosis in older age suggesting that the decades-long protective effect of low-risk status might be mediated through a lower burden of quantitative and qualitative features of atherosclerotic plaque.

Favorable Cardiovascular Health at Young and Middle Ages and Dementia in Older Age-The CHA Study.

Background Data are sparse on the association of cardiovascular health ( CVH ) in younger/middle age with the incidence of dementia later in life. Methods and Results We linked the CHA (Chicago Heart Association Detection Project in Industry) study data, assessed in 1967 to 1973, with 1991 to 2010 Medicare and National Death Index data. Favorable CVH was defined as untreated systolic blood pressure/diastolic blood pressure ≤120/≤80 mm Hg, untreated serum total cholesterol <5.18 mmol/L, not smoking, bone mass index <25 kg/m2, and no diabetes mellitus. International Classification of Diseases, Ninth Revision (ICD-9) codes and claims dates were used to identify the first dementia diagnosis. Cox models were used to estimate hazard ratios of incident dementia after age 65 years by baseline CVH status. Among 10 119 participants baseline aged 23 to 47 years, 32.4% were women, 9.2% were black, and 7.3% had favorable baseline CVH . The incidence rate of dementia during follow-up after age 65 was 13.9%. After adjustment, the hazard ratio for incident dementia was lowest in those with favorable baseline CVH and increased with higher risk factor burden ( P-trend<0.001). The hazards of dementia in those with baseline favorable, moderate, and 1-only high-risk factor were lower by 31%, 26%, and 20%, respectively, compared with those with ≥2 high-risk factors. The association was attenuated but remained significant ( P-trend<0.01) when the model was further adjusted for competing risk of death. Patterns of associations were similar for men and women, and for those with a higher and lower baseline education level. Conclusions In this large population-based study, a favorable CVH profile at younger age is associated with a lower risk of dementia in older age.

Cardiovascular health in young and middle adulthood and medical care utilization and costs at older age - The Chicago Heart Association Detection Project Industry (CHA).

It is unclear how long-term medical utilization and costs from diverse care settings and their age-related patterns may differ by cardiovascular health (CVH) status earlier in adulthood. We followed 17,195 participants of the Chicago Heart Association Detection Project Industry (1967-1973) with linked Medicare claims (1992 to 2010). Baseline CVH is a composite measure of blood pressure, body mass index, diabetes, cholesterol, and smoking and includes four mutually exclusive strata: all factors were favorable (5.5%), one or more factors were elevated but none high (20.3%), one factor was high (40.9%), and two or more factors were high (33.2%). We assessed differences in the quantities (using negative binomial models) of and costs (using quantile regressions) for inpatient admissions, ambulatory care, home health care, and others between less favorable and all favorable CVH. All analyses adjusted for baseline age, race, sex, education, age at follow-up, year, state of residence, and death. We found that all favorable CVH in earlier adulthood was associated with lower long-term utilization and costs in all settings and the gap widened with age. Compared to all favorable CVH, the annual number of acute inpatient admissions per person was 79% greater (p-value < 0.001) for poor CVH, the median annual Medicare payment per person was $640 greater (41%, p-value < 0.001), and the mean was $4628 greater (67%, p-value < 0.001). The cost differences were greatest for acute inpatient, followed by ambulatory, post-acute inpatient, home health, and other. Early prevention efforts may potentially result in compressed all-cause morbidity in later years of age, along with reductions in resource use and health care costs for associated conditions.

Long-term favorable cardiovascular risk profile and 39-year development of major and minor electrocardiographic abnormalities - The Chicago Healthy Aging Study (CHAS).

BACKGROUND: Data are limited on long-term associations of favorable cardiovascular risk profile (i.e., low-risk) and changes in risk profile with ECG abnormality development. METHODS: The Chicago Healthy Aging Study (CHAS) involved re-examination of 1395 participants, ages 65-84 years in 2007-10, free of baseline major ECG abnormalities or MI in 1967-1973. Stratified sampling method was used to recruit participants based on their baseline risk profile (low-risk and not low-risk). Low-risk status was defined as untreated SBP/DBP ≤ 120/≤80 mm Hg, untreated total cholesterol <200 mg/dl, not smoking, BMI <25 kg/m2, and no diabetes. ECG abnormalities were defined by Minnesota code criteria. Multinomial logistic regression was used. RESULTS: There were 28% women, 9% blacks, and 20% with baseline low-risk status. At follow-up, 21% developed ≥1 major ECG abnormalities, and 58% developed ≥1 minor ECG abnormalities. With multivariable adjustment, compared to those with 2 + high-risk factors, odds for developing from normal to any major ECG abnormalities were lower by 57%, 49%, and 35%, respectively, in persons with low-risk, any moderate-risk, and 1 high-risk factor (P-trend = 0.002). Findings were similar for some common specific subtypes of major and minor abnormalities. Associations were mainly due to baseline smoking and BMI. Remaining free of high-risk factors, or improving risk profile over time was also associated with lower major ECG abnormality development by 70% vs. always having any high-risk factor. CONCLUSIONS: Favorable CVD risk profile earlier in life and maintenance or improvement in risk profile over time are associated with lower risk of ECG abnormality development at older age.

Weekly sleep trajectories and their associations with obesity and hypertension in the Hispanic/Latino population.

Study Objectives: To identify weekly sleep trajectories (sleep pattern changing by day over a course of week) of specific characteristics and examine the associations between trajectory classes and obesity and hypertension. Methods: A total of 2043 participants (mean age 46.9, 65.5% female) completed at least 7 days of actigraphy aged 18-64 from the Sueño ancillary study of the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). Weekly sleep trajectories for three daily level measures (wake after sleep onset [WASO], daytime napping duration, and intranight instability index) were identified using latent class growth models. The outcomes were obesity and hypertension. Results: Using the trajectory with low-stable WASO as reference, the trajectory classes with increasing and high-concave patterns had significantly higher odds for obesity (OR 3.64 [1.23-10.84]) and hypertension (OR 5.25 [1.33, 20.82]), respectively. Compared with individuals with a low-stable napping duration trajectory, those with the high-concave pattern class were associated with hypertension (OR 2.27 [1.10-4.67]), and the association was mediated in part by obesity (OR 1.11 [1.00-1.22]). Individuals in the high intranight instability index trajectory had significantly larger likelihood for both obesity (OR 1.90 [1.26-2.86]) and hypertension (OR 1.86 [1.13-3.06]) compared with those in the low intranight instability index trajectory. Conclusions: Weekly trajectories varied for WASO, daytime napping duration, and intranight instability index. The trajectories with relatively larger values for these three measures were associated with greater risk for obesity and hypertension. These findings suggest that a stable pattern with relatively small weekly and nightly variability may be beneficial for cardiovascular health.

Relation of Dietary Sodium (Salt) to Blood Pressure and Its Possible Modulation by Other Dietary Factors: The INTERMAP Study.

Available data indicate that dietary sodium (as salt) relates directly to blood pressure (BP). Most of these findings are from studies lacking dietary data; hence, it is unclear whether this sodium-BP relationship is modulated by other dietary factors. With control for multiple nondietary factors, but not body mass index, there were direct relations to BP of 24-hour urinary sodium excretion and the urinary sodium/potassium ratio among 4680 men and women 40 to 59 years of age (17 population samples in China, Japan, United Kingdom, and United States) in the INTERMAP (International Study on Macro/Micronutrients and Blood Pressure), and among its 2195 American participants, for example, 2 SD higher 24-hour urinary sodium excretion (118.7 mmol) associated with systolic BP 3.7 mm Hg higher. These sodium-BP relations persisted with control for 13 macronutrients, 12 vitamins, 7 minerals, and 18 amino acids, for both sex, older and younger, blacks, Hispanics, whites, and socioeconomic strata. With control for body mass index, sodium-BP-but not sodium/potassium-BP-relations were attenuated. Normal weight and obese participants manifested significant positive relations to BP of urinary sodium; relations were weaker for overweight people. At lower but not higher levels of 24-hour sodium excretion, potassium intake blunted the sodium-BP relation. The adverse association of dietary sodium with BP is minimally attenuated by other dietary constituents; these findings underscore the importance of reducing salt intake for the prevention and control of prehypertension and hypertension.

Description and initial evaluation of incorporating electronic follow-up of study participants in a longstanding multisite cohort study.

BACKGROUND: The objective of this study was to evaluate a pilot program that allowed Chicago field center participants of the Coronary Artery Risk Development in Young Adults (CARDIA) study to submit follow-up information electronically (eCARDIA). METHODS: Chicago field center participants who provided email addresses were invited to complete contact information and follow-up questionnaires on medical conditions electronically in 2012-2013. Sociodemographic characteristics were compared between those who did and did not complete follow-up electronically. The number of participant contacts by CARDIA staff needed before follow-up was completed was also evaluated. RESULTS: Blacks and low socioeconomic position individuals were less likely to complete follow-up using the electronic questionnaire. Participants who used the electronic questionnaire for follow-up needed fewer contacts (e.g., median 1 contact compared with 3for contact information follow-up), but they also needed fewer contacts prior to eCARDIA (median 1 before and after eCARDIA). CONCLUSIONS: Findings suggest other approaches will be needed to maintain contact and elicit follow-up information from harder-to-reach individuals.

Optimal Levels of All Major Cardiovascular Risk Factors in Younger Age and Functional Disability in Older Age: The Chicago Heart Association Detection Project in Industry 32-Year Follow-Up Health Survey.

BACKGROUND: The associations of optimal levels of all major cardiovascular disease risk factors, that is, low risk, in younger age with subsequent cardiovascular disease morbidity and mortality have been well documented. However, little is known about associations of low-risk profiles in younger age with functional disability in older age. METHODS AND RESULTS: The sample included 6014 participants from the Chicago Heart Association Detection Project in Industry Study. Low-risk status, defined as untreated systolic/diastolic blood pressure ≤120/≤80 mm Hg, untreated serum total cholesterol <5.18 mmol/l, not smoking, body mass index < 25 kg/m(2), and no diabetes mellitus, was assessed at baseline (1967 to 1973). Functional disability, categorized as (1) any disability in activities of daily living (ADLs), (2) any disability in instrumental ADLs but not in ADL, or (3) no disability, was assessed from the 2003 health survey. There were 39% women, 4% Black, with a mean age of 43 years and 6% low-risk status at baseline. After 32 years, 7% reported having limitations in performing any ADL and 11% in any instrumental ADL only. The prevalence of any ADL limitation was lowest in low-risk people and increased in a graded fashion with less-favorable risk factor groups (P trend <0.001). Compared with those with 2+ high-risk factors, the multivariable-adjusted odds of having any disability in ADLs versus no disability in people with low risk, any moderate risk, and 1 high-risk factor at baseline were lower by 58%, 48%, and 37%, respectively. Results were similar for instrumental ADLs, in both men and women. CONCLUSIONS: Having an optimal cardiovascular disease risk factor profile at younger age is associated with the lowest rate of functional disability in older age.

Favorable Levels of All Major Cardiovascular Risk Factors at Younger Ages and High-Sensitivity C-Reactive Protein 39 Years Later -The Chicago Healthy Aging Study.

OBJECTIVES: Examine associations of favorable levels of all cardiovascular disease (CVD) risk factors (RFs) [i.e., low risk (LR)] at younger ages with high sensitivity C-reactive protein (hs-CRP) at older ages. METHODS: There were 1,324 participants ages 65-84 years with hs-CRP ≤ 10mg/l from the Chicago Healthy Aging Study (2007-2010), CVD RFs assessed at baseline (1967-73) and 39 years later. LR was defined as untreated blood pressure (BP) ≤120/≤80 mmHg, untreated serum total cholesterol <200 mg/dL, body mass index (BMI) <25 kg/m2, not smoking, no diabetes. Hs-CRP was natural log-transformed or dichotomized as elevated (≥3 mg/l or ≥2 mg/l) vs. otherwise. RESULTS: With multivariable adjustment, the odds ratios (95% confidence intervals) for follow-up hs-CRP ≥3 mg/ in participants with baseline 0RF, 1RF and 2+RFs compared to those with baseline LR were 1.35 (0.89-2.03), 1.61(1.08-2.40) and 1.69(1.04-2.75), respectively. There was also a graded, direct association across four categories of RF groups with follow-up hs-CRP levels (ß coefficient/P-trend = 0.18/0.014). Associations were mainly due to baseline smoking and BMI, independent of 39-year change in BMI levels. Similar trends were observed in gender-specific analyses. CONCLUSIONS: Favorable levels of all CVD RFs in younger age are associated with lower hs-CRP level in older age.

Isolated systolic hypertension in young and middle-aged adults and 31-year risk for cardiovascular mortality: the Chicago Heart Association Detection Project in Industry study.

BACKGROUND: Isolated systolic hypertension (ISH), defined as systolic blood pressure (SBP) ≥140 mm Hg and diastolic blood pressure (DBP) <90 mm Hg, in younger and middle-aged adults is increasing in prevalence. OBJECTIVE: The aim of this study was to assess the risk for cardiovascular disease (CVD) with ISH in younger and middle-aged adults. METHODS: CVD risks were explored in 15,868 men and 11,213 women 18 to 49 years of age (mean age 34 years) at baseline, 85% non-Hispanic white, free of coronary heart disease (CHD) and antihypertensive therapy, from the Chicago Heart Association Detection Project in Industry study. Participant classifications were as follows: 1) optimal-normal blood pressure (BP) (SBP <130 mm Hg and DBP <85 mm Hg); 2) high-normal BP (130 to 139/85 to 89 mm Hg); 3) ISH; 4) isolated diastolic hypertension (SBP <140 mm Hg and DBP ≥90 mm Hg); and 5) systolic diastolic hypertension (SBP ≥140 mm Hg and DBP ≥90 mm Hg). RESULTS: During a 31-year average follow-up period (842,600 person-years), there were 1,728 deaths from CVD, 1,168 from CHD, and 223 from stroke. Cox proportional hazards models were adjusted for age, race, education, body mass index, current smoking, total cholesterol, and diabetes. In men, with optimal-normal BP as the reference stratum, hazard ratios for CVD and CHD mortality risk for those with ISH were 1.23 (95% confidence interval [CI]: 1.03 to 1.46) and 1.28 (95% CI: 1.04 to 1.58), respectively. ISH risks were similar to those with high-normal BP and less than those associated with isolated diastolic hypertension and systolic diastolic hypertension. In women with ISH, hazard ratios for CVD and CHD mortality risk were 1.55 (95% CI: 1.18 to 2.05) and 2.12 (95% CI: 1.49 to 3.01), respectively. ISH risks were higher than in those with high-normal BP or isolated diastolic hypertension and less than those associated with systolic diastolic hypertension. CONCLUSIONS: Over long-term follow-up, younger and middle-aged adults with ISH had higher relative risk for CVD and CHD mortality than those with optimal-normal BP.

Association of depressive symptoms, trait anxiety, and perceived stress with subclinical atherosclerosis: results from the Chicago Healthy Aging Study (CHAS).

OBJECTIVE: Examine the association between multiple psychological factors (depressive symptoms, trait anxiety, perceived stress) and subclinical atherosclerosis in older age. METHOD: This cross-sectional study included 1101 adults ages 65-84 from the Chicago Healthy Aging Study (CHAS - 2007-2010). Previously validated self-report instruments were used to assess psychological factors. Non-invasive methods were used to assess subclinical atherosclerosis in two regions of the body, i.e., ankle-brachial blood pressure index (ABI) and coronary artery calcification (CAC). Multivariate logistic regression was used to examine the association between each psychological measure and subclinical atherosclerosis, after the adjustment for socio-demographic factors, sleep quality, young adulthood/early middle age and late-life CVD risk status, and psychological ill-being as appropriate. RESULTS: The burden of major cardiovascular disease risk factors did not significantly differ across tertiles of psychological factors. In multivariate adjusted models, trait anxiety was associated with calcification: those in the second tertile were significantly more likely to have CAC >0 compared to those in the lowest anxiety tertile [OR=1.68; 95% CI=1.09-2.58], but no significant difference was observed for Tertile III of trait anxiety [OR=1.31; 95% CI=0.75-2.27]. No association was seen between psychological measures and ABI. CONCLUSION: Of several psychological factors, only trait anxiety was significantly associated with CAC.

Major and minor electrocardiographic abnormalities and their association with underlying cardiovascular disease and risk factors in Hispanics/Latinos (from the Hispanic Community Health Study/Study of Latinos).

The association of electrocardiographic (ECG) abnormalities with cardiovascular disease and risk factors has been extensively studied in whites and African-Americans. Comparable data have not been reported in Hispanics/Latinos. The Hispanic Community Health Study/Study of Latinos (HCHS/SOL) is a multicenter, community-based, prospective cohort study of men and women of diverse backgrounds aged 18 to 74 years who self-identified as Hispanic/Latinos. Participants (n = 16,415) enrolled from March 2008 to June 2011. We describe the prevalence of minor and major ECG abnormalities and examined their cross-sectional associations with cardiovascular disease and risk factors. The Minnesota code criteria were used to define minor and major ECG abnormalities. Previous cardiovascular disease and risk factors were based on data obtained at baseline examination. Significant differences in prevalent ECG findings were found between men and women. Major ECG abnormalities were present in 9.2% (95% confidence interval 8.3 to 10.1) of men and 6.6% (95% confidence interval 5.8 to 7.3) of women (p <0.0001). The odds of having major ECG abnormalities significantly increased with age, presence of ≥3 cardiovascular risk factors, and prevalent cardiovascular disease, in both men and women. Significant differences in major ECG abnormalities were found among the varying groups; Puerto Ricans and Dominicans had more major abnormalities compared with Mexican men and women. In conclusion, in a large cohort of Hispanic/Latino men and women, prevalence of major abnormalities was low, yet strong associations of major ECG abnormalities with cardiovascular disease and risk factors were observed in both men and women.

Chicago Healthy Aging Study: objectives and design.

Investigators in the Chicago Healthy Aging Study (CHAS) reexamined 1,395 surviving participants aged 65-84 years (28% women) from the Chicago Heart Association Detection Project in Industry (CHA) 1967-1973 cohort whose cardiovascular disease (CVD) risk profiles were originally ascertained at ages 25-44 years. CHAS investigators reexamined 421 participants who were low-risk (LR) at baseline and 974 participants who were non-LR at baseline. LR was defined as having favorable levels of 4 major CVD risk factors: serum total cholesterol level <200 mg/dL and no use of cholesterol-lowering medication; blood pressure 120/≤80 mm Hg and no use of antihypertensive medication; no current smoking; and no history of diabetes or heart attack. While the potential of LR status in overcoming the CVD epidemic is being recognized, the long-term association of LR with objectively measured health in older age has not been examined. It is hypothesized that persons who were LR in 1967-1973 and have survived to older age will have less clinical and subclinical CVD, lower levels of inflammatory markers, and better physical performance/functioning and sleep quality. Here we describe the rationale, objectives, design, and implementation of this longitudinal epidemiologic study, compare baseline and follow-up characteristics of participants and nonparticipants, and highlight the feasibility of reexamining study participants after an extended period postbaseline with minimal interim contact.

Lifetime risk for heart failure among white and black Americans: cardiovascular lifetime risk pooling project.

OBJECTIVES: This study sought to estimate lifetime risk for heart failure (HF) by sex and race. BACKGROUND: Prior estimates of lifetime risk for developing HF range from 20% to 33% in predominantly white cohorts. Short-term risks for HF appear higher for blacks than whites, but only limited comparisons of lifetime risk for HF have been made. METHODS: Using public-release and internal datasets from National Heart, Lung, and Blood Institute-sponsored cohorts, we estimated lifetime risks for developing HF to age 95 years, with death free of HF as the competing event, among participants in the CHA (Chicago Heart Association Detection Project in Industry), ARIC (Atherosclerosis Risk in Communities), and CHS (Cardiovascular Health Study) cohorts. RESULTS: There were 39,578 participants (33,652 [85%] white; 5,926 [15%] black) followed for 716,976 person-years; 5,983 participants developed HF. At age 45 years, lifetime risks for HF through age 95 years in CHA and CHS were 30% to 42% in white men, 20% to 29% in black men, 32% to 39% in white women, and 24% to 46% in black women. Results for ARIC demonstrated similar lifetime risks for HF in blacks and whites through age 75 years (limit of follow-up). Lifetime risk for HF was higher with higher blood pressure and body mass index at all ages in both blacks and whites, and did not diminish substantially with advancing index age. CONCLUSIONS: These are among the first data to compare lifetime risks for HF between blacks and whites. Lifetime risks for HF are high and appear similar for black and white women, yet are somewhat lower for black compared with white men due to competing risks.

Lifetime risks of cardiovascular disease.

BACKGROUND: The lifetime risks of cardiovascular disease have not been reported across the age spectrum in black adults and white adults. METHODS: We conducted a meta-analysis at the individual level using data from 18 cohort studies involving a total of 257,384 black men and women and white men and women whose risk factors for cardiovascular disease were measured at the ages of 45, 55, 65, and 75 years. Blood pressure, cholesterol level, smoking status, and diabetes status were used to stratify participants according to risk factors into five mutually exclusive categories. The remaining lifetime risks of cardiovascular events were estimated for participants in each category at each age, with death free of cardiovascular disease treated as a competing event. RESULTS: We observed marked differences in the lifetime risks of cardiovascular disease across risk-factor strata. Among participants who were 55 years of age, those with an optimal risk-factor profile (total cholesterol level, <180 mg per deciliter [4.7 mmol per liter]; blood pressure, <120 mm Hg systolic and 80 mm Hg diastolic; nonsmoking status; and nondiabetic status) had substantially lower risks of death from cardiovascular disease through the age of 80 years than participants with two or more major risk factors (4.7% vs. 29.6% among men, 6.4% vs. 20.5% among women). Those with an optimal risk-factor profile also had lower lifetime risks of fatal coronary heart disease or nonfatal myocardial infarction (3.6% vs. 37.5% among men, <1% vs. 18.3% among women) and fatal or nonfatal stroke (2.3% vs. 8.3% among men, 5.3% vs. 10.7% among women). Similar trends within risk-factor strata were observed among blacks and whites and across diverse birth cohorts. CONCLUSIONS: Differences in risk-factor burden translate into marked differences in the lifetime risk of cardiovascular disease, and these differences are consistent across race and birth cohorts.

Prospective relationship of low cardiovascular risk factor profile at younger ages to ankle-brachial index: 39-year follow-up--the Chicago Healthy Aging Study.

BACKGROUND: Data are sparse regarding the long-term association of favorable levels of all major cardiovascular disease risk factors (RFs) (ie, low risk [LR]) with ankle-brachial index (ABI). METHODS AND RESULTS: In 2007-2010, the Chicago Healthy Aging Study reexamined a subset of participants aged 65 to 84 years from the Chicago Heart Association Detection Project in Industry cohort (baseline examination, 1967-1973). RF groups were defined as LR (untreated blood pressure ≤ 120/≤ 80 mm Hg, untreated serum cholesterol <200 mg/dL, body mass index <25 kg/m(2), not smoking, no diabetes) or as 0 RFs, 1 RF, or 2+ RFs based on the presence of blood pressure ≥ 140/≥ 90 mm Hg or receiving treatment, serum cholesterol ≥ 240 mg/dL or receiving treatment, body mass index ≥ 30 kg/m(2), smoking, or diabetes. ABI at follow-up was categorized as indicating PAD present (≤ 0.90), as borderline PAD (0.91 to 0.99), or as normal (1.00 to 1.40). We included 1346 participants with ABI ≤ 1.40. After multivariable adjustment, the presence of fewer baseline RFs was associated with a lower likelihood of PAD at 39-year follow-up (P for trend is <0.001). Odds ratios (95% CIs) for PAD in persons with LR, 0 RFs, or 1 RF compared with those with 2+ RFs were 0.14 (0.05 to 0.44), 0.28 (0.13 to 0.59), and 0.33 (0.16 to 0.65), respectively; findings were similar for borderline PAD (P for trend is 0.005). The association was mainly due to baseline smoking status, cholesterol, and diabetes. Remaining free of adverse RFs or improving RF status over time was also associated with PAD. CONCLUSIONS: LR profile in younger adulthood (ages 25 to 45) is associated with the lowest prevalence of PAD and borderline PAD 39 years later.

Biomarkers of inflammation and thrombosis as predictors of near-term mortality in patients with peripheral arterial disease: a cohort study.

BACKGROUND: Traditional atherosclerotic risk factors predict long-term cardiovascular disease events but are poor predictors of near-term events. OBJECTIVE: To determine whether elevated levels of D-dimer and biomarkers of inflammation were more closely associated with near-term than long-term mortality in patients with lower-extremity peripheral arterial disease (PAD) and whether greater increases in biomarker levels were associated with higher mortality rates during the first year after the increase than during later years. DESIGN: Prospective cohort study with a mean follow-up of 3.4 years. SETTING: Academic medical center. PATIENTS: 377 men and women with PAD. MEASUREMENTS: Mortality within 1 year after biomarker measurement, 1 to 2 years after biomarker measurement, and 2 to 3 years after biomarker measurement. Cox regression analyses were used to evaluate associations of biomarkers levels and changes in biomarkers with cardiovascular and all-cause mortality. Hazard ratios were calculated for each 1-unit increase in log1.5(biomarker level). Analyses were adjusted for age, sex, race, comorbid conditions, ankle-brachial index, and other confounders. RESULTS: Seventy-six patients (20%) died during follow-up. Higher levels of D-dimer, C-reactive protein, and serum amyloid A were associated with higher all-cause mortality among patients who died within 1 year after biomarker measurement (hazard ratio, 1.20 [95% CI, 1.08 to 1.33], 1.13 [CI, 1.05 to 1.21], and 1.12 [CI, 1.04 to 1.20], respectively; P < 0.001, P < 0.001, and P = 0.003) and among patients who died 1 to 2 years after biomarker measurement (hazard ratio, 1.14 [CI, 1.02 to 1.27], 1.15 [CI, 1.06 to 1.24], and 1.13 [CI, 1.04 to 1.24]; P = 0.022, P = 0.001, and P = 0.005]). However, higher levels of each biomarker were not associated with all-cause mortality for deaths occurring 2 to 3 years after biomarker measurement. Similar results were observed for cardiovascular mortality. Greater increases in each biomarker were associated with higher all-cause and cardiovascular mortality during the following year. LIMITATION: The small number of deaths limited the statistical power of the analyses. CONCLUSION: Among persons with PAD, circulating levels of D-dimer and inflammatory markers are higher in the 1 to 2 years before death than in periods more remote from death. Increasing levels of D-dimer and inflammatory biomarkers are independently associated with higher mortality in persons with PAD.

Resting heart rate in middle age and diabetes development in older age.

OBJECTIVE: Based on prior research showing inverse associations between heart rate and life expectancy, we tested the hypothesis that adults with higher resting heart rate in middle age were more likely to have diagnosed diabetes or to experience diabetes mortality in older age (>65 years). RESEARCH DESIGN AND METHODS: Resting heart rate was measured at baseline (1967-1973) in the Chicago Heart Association Detection Project in Industry. We used Medicare billing records to identify diabetes-related hospital claims and non-hospital-based diabetes expenses from 1992 to 2002 in 14,992 participants aged 35-64 years who were free from diabetes at baseline. Diabetes-related mortality was determined from 1984 to 2002 using National Death Index codes 250.XX (ICD-8 and -9) and E10-E14 (ICD-10). RESULTS: After age 65, 1,877 participants had diabetes-related hospital claims and 410 participants had any mention of diabetes on their death certificate. The adjusted (demographic characteristics, cigarette smoking, and years of Medicare eligibility) odds of having a diabetes-related claim was approximately 10% higher (odds ratio [OR] 1.10 [95% CI 1.05-1.16]) per 12 bpm higher baseline heart rate. Following adjustment for BMI and postload glucose at baseline, the association attenuated to nonsignificance. Higher heart rate was associated with diabetes mortality in adults aged 35-49 years at baseline following adjustment for postload glucose and BMI (1.21 [1.03-1.41]). CONCLUSIONS: Higher resting heart rate is associated with diabetes claims and mortality in older age and is only due in part to BMI and concurrently measured glucose.
