Disability and Incident Coronary Heart Disease in Older Community‐Dwelling Adults: The Three‐City Study

OBJECTIVES: To prospectively assess the association between disability and incident fatal and nonfatal coronary heart disease (CHD) in older adults free of cardiovascular disease (CVD). DESIGN: A French multicenter prospective population‐based cohort of 9,294 subjects, aged 65 and older at baseline, recruited between 1999 and 2001 and followed for 6 years. SETTING: Three cities in France: Bordeaux in the southwest, Dijon in the northeast, and Montpellier in the southeast. PARTICIPANTS: Seven thousand three hundred fifty‐four participants with no history of CVD and with available information on disability status. Subjects were categorized at baseline as having no disability, mild disability (mobility only), and moderate or severe disability (mobility plus activities of daily living or instrumental activities of daily living). MEASUREMENTS: Incident fatal and nonfatal coronary events (angina pectoris, myocardial infarction, revascularization procedures, and CHD death). RESULTS: At baseline, the mean level of the risk factors increased gradually with the severity of disability. After a median follow‐up of 5.2 years, 264 first coronary events, including 55 fatal events, occurred. After adjustment for cardiovascular risk factors, participants with moderate or severe disability had a 1.7 times (95% confidence interval (CI)=1.0–2.7) greater risk of overall CHD than nondisabled subjects, whereas those with mild disability were not at greater CHD risk. An association was also found with fatal CHD, for which the risk increased gradually with the severity of disability (hazard ratio (HR)_{mild disability}=1.7, 95% CI=0.8–3.6; HR_{moderate/severe disability}=3.5, 95% CI=1.3–9.3; P for trend=.01). CONCLUSION: In older community‐dwelling adults, the association between disability and incident CHD is mostly due to an association with fatal CHD.     

Depression and Anxiety in Women with Heart Disease

Depression and anxiety are extremely common conditions but are even more common in persons living with cardiovascular disease. Both conditions occur more frequently in women living with cardiovascular disease compared with men. Studies have demonstrated a link between coronary artery disease and depression, with an increased prevalence of depression in younger women living with CVD. Depression and anxiety are independent risk factors for cardiovascular disease and are associated with worse outcomes in those living with cardiovascular disease, particularly women. The purpose of this paper is to review the sex-based epidemiology of depression and anxiety in CVD and their possible mechanisms of impacting CVD risk factors and CVD outcomes in women with CVD.     

Effects of long-term and ongoing cardiac rehabilitation in elderly patients with coronary heart disease

The authors assessed the effect of very long-term cardiac rehabilitation (over 1 year) on exercise tolerance and coronary heart disease risk factors in patients older than 80 years with coronary heart disease relative to an elderly cohort without coronary heart disease. Included in this retrospective analysis were patients older than 80 at the time of their last evaluation who had completed at least 1 year of a cardiac prevention and exercise training program. A total of 43 coronary heart disease patients and 15 age-matched healthy subjects were included in this study. Long-term cardiac rehabilitation in very elderly coronary heart disease patients was shown to be feasible and effective in improving functional capacity (+5.4% after 1 year; P< .05) and risk factor control, and slowing the decline in exercise tolerance that occurs with normal aging.     

The effect of major depression on functional status in patients with coronary artery disease

OBJECTIVE: To examine the effect of major depression on reported functional status in a group of patients with coronary artery disease (CAD). SETTING: An inpatient cardiology service. PARTICIPANTS: Three hundred thirty-five inpatients with coronary artery disease who were free of dementia, Parkinson's disease, and other primary neurological illnesses. MEASUREMENTS: Duke Depression Evaluation Schedule, a structured psychiatric interview which included the Diagnostic Interview Schedule depression subscale, the Cumulative Illness Rating Scale, and two scales for measuring instrumental and self-maintenance activities of daily living. RESULTS: Twenty-seven subjects met DSM-IV criteria for major depression. Compared with subjects without major depression, depressed subjects were more than twice as likely to report a self-maintenance ADL deficit and were significantly more likely to report an IADL deficit than were nondepressed subjects (93 vs 71%). In regression models, female gender, older age, greater medical illness severity, and presence of major depression were significant predictors of self-maintenance ADL disability; and female gender, older age, greater medical severity, and presence of major depression significantly predicted greater IADL impairment. CONCLUSION: The presence of major depression was associated with functional disability in patients with CAD. Further research is needed to clarify whether antidepressant treatment significantly impacts both affective symptoms and functional status in patients with coronary heart disease.     

Cardiovascular Risk Factors and Incident Acute Renal Failure in Older Adults: The Cardiovascular Health Study

Background and objectives: Although the elderly are at increased risk for acute renal failure, few prospective studies have identified risk factors for acute renal failure in the elderly.Design, setting, participants, & measurements: The associations of cardiovascular disease risk factors, subclinical cardiovascular disease, and clinical coronary heart disease with the risk for development of acute renal failure were examined in older adults in the Cardiovascular Health Study, a prospective cohort study of community-dwelling older adults. Incident hospitalized cases of acute renal failure were identified through hospital discharge International Classification of Diseases, Ninth Revision codes and confirmed through physician diagnoses of acute renal failure in discharge summaries.Results: Acute renal failure developed in 225 (3.9%) of the 5731 patients during a median follow-up period of 10.2 yr. In multivariate analyses, diabetes, current smoking, hypertension, C-reactive protein, and fibrinogen were associated with acute renal failure. Prevalent coronary heart disease was associated with incident acute renal failure, and among patients without prevalent coronary heart disease, subclinical vascular disease measures were also associated with acute renal failure: Low ankle-arm index (≤0.9), common carotid intima-media thickness, and internal carotid intima-media thickness.Conclusions: In this large, population-based, prospective cohort study, cardiovascular risk factors and both subclinical and clinical vascular disease were associated with incident acute renal failure in the elderly.Acute renal failure (ARF) occurs most commonly in older adults and is associated with significant morbidity and mortality, with death rates among hospitalized patients ranging from 25 to >70% (1–4). Despite the prevalence of ARF in elderly adults, few studies have examined potential risk factors (5–7), and no studies have examined risk factors in the elderly. The limited data from small studies suggest that cardiovascular disease (CVD) risk factors, such as hypertension, diabetes, and inflammatory markers, and clinical CVD may be associated not only with chronic kidney disease (CKD) but also ARF. These associations may be particularly important in the elderly, in whom CVD is prevalent. We hypothesized that CVD risk factors and subclinical and clinical disease would be associated prospectively with the risk for development of ARF in older adults. To address these hypotheses, we evaluated the associations of these characteristics with incident ARF in the Cardiovascular Health Study (CHS), a large cohort study of older adults. If our hypotheses are correct, then prospective identification of risk factors for ARF in the elderly may suggest potential subgroups of this high-risk population that may merit additional attention or intervention.     

Alcohol consumption and risk of coronary heart disease in older adults: the Cardiovascular Health Study

OBJECTIVES: To evaluate several aspects of the relationship between alcohol use and coronary heart disease in older adults, including beverage type, mediating factors, and type of outcome. DESIGN: Prospective cohort study. SETTING: Four U.S. communities. PARTICIPANTS: Four thousand four hundred ten adults aged 65 and older free of cardiovascular disease at baseline. MEASUREMENTS: Risk of incident myocardial infarction or coronary death according to self-reported consumption of beer, wine, and spirits ascertained yearly. RESULTS: During an average follow-up period of 9.2 years, 675 cases of incident myocardial infarction or coronary death occurred. Compared with long-term abstainers, multivariate relative risks of 0.90 (95% confidence interval (CI)=0.71-1.14), 0.93 (95% CI=0.73-1.20), 0.76 (95% CI=0.53-1.10), and 0.58 (95% CI=0.39-0.86) were found in consumers of less than one, one to six, seven to 13, and 14 or more drinks per week, respectively (P for trend=.007). Associations were similar for secondary coronary outcomes, including nonfatal and fatal events. No strong mediators of the association were identified, although fibrinogen appeared to account for 9% to 10% of the relationship. The associations were statistically similar for intake of wine, beer, and liquor and generally similar in subgroups, including those with and without an apolipoprotein E4 allele. CONCLUSION: In this population, consumption of 14 or more drinks per week was associated with the lowest risk of coronary heart disease, although clinicians should not recommend moderate drinking to prevent coronary heart disease based on this evidence alone, because current National Institute on Alcohol Abuse and Alcoholism guidelines suggest that older adults limit alcohol intake to one drink per day.     

Association of drinking pattern and alcohol beverage type with the prevalence of metabolic syndrome, diabetes, coronary heart disease, stroke, and peripheral arterial disease in a Mediterranean cohort

The purpose of this study was to investigate the relationship between alcohol consumption and the prevalence of the metabolic syndrome (MetS), type 2 diabetes mellitus (DM), coronary heart disease (CHD), stroke, peripheral arterial disease (PAD), and overall cardiovascular disease (CVD) in a Mediterranean cohort. It consisted of a cross-sectional analysis of a representative sample of Greek adults (n = 4,153) classified as never, occasional, mild, moderate, or heavy drinkers. Cases with overt CHD, stroke, or PAD were recorded. In our population, 17% were never, 23% occasional, 27% mild, 24% moderate, and 9% heavy drinkers. Moderate alcohol consumption was associated with a lower trend for the prevalence of the MetS (P = .0001), DM (P < .0001), CHD (P = .0002), PAD (P = .005), and overall CVD (P = .001) but not stroke compared with no alcohol use. Heavy drinking was associated with an increase in the prevalence of all of these disease states. Wine consumption was associated with a slightly better effect than beer or spirits consumption on the prevalence of total CVD, and beer consumption was associated with a better effect than spirits consumption. Alcohol intake was positively related with body weight, high-density lipoprotein cholesterol levels, and hypertension. Moderate alcohol consumption is associated with a lower prevalence of the MetS, DM, PAD, CHD, and overall CVD but not stroke compared with no alcohol use in a Mediterranean population. Heavy drinking was associated with an increase in the prevalence of all of these disease states. Advice on alcohol consumption should probably mainly aim at reducing heavy drinking.     

Effect of statin (HMG-Co-A-Reductase Inhibitor) use on 1-year mortality and hospitalization rates in older patients with cardiovascular disease living in nursing homes

OBJECTIVES: To quantify the effect of statins on 1-year mortality, hospitalizations, and decline in physical function among patients with cardiovascular disease (CVD) aged 65 and older living in nursing homes. DESIGN: Retrospective cohort study. SETTING: All Medicare/Medicaid certified nursing homes (N = 1,492) in Maine, New York, Mississippi, and South Dakota. PARTICIPANTS: We identified 51,559 older patients with CVD from a population database that merged sociodemographic data and functional, clinical, and drug treatments from more than 300,000 newly admitted nursing home residents from 1992 to 1997. Statin users (n = 1,313) were matched with nonusers (n = 1,313) in the same facilities. MEASUREMENTS: All-cause mortality, hospitalization, combined endpoint of mortality or hospitalization, and decline in physical function were determined at 1 year, and survival analysis was performed. RESULTS: Prevalence of statin use in this frail older cohort with CVD was 2.6%. Statin use varied by age, gender, comorbid condition, medication use, and cognitive and physical function. One-year mortality was 229/1,000 person-years in the statin group and 404/1,000 person-years in the nonusers, with an adjusted hazard rate ratio (HRR) of 0.69, 95% confidence interval (CI) = 0.58-0.81. The estimated number needed to treat was seven (95% CI = 5-13). This association with improved all-cause mortality was evident for women and men and for age groups 75 to 84, and 85 and older. CONCLUSION: Statin therapy is associated with improved clinical outcomes, including reduction in 1-year all-cause mortality, and the combined endpoint of death or hospitalization in a frail older population with CVD. Some caution should be taken in interpreting these results because potential bias from residual confounding could affect these results.     

Two-year changes in blood pressure and subsequent risk of cardiovascular disease in men

BACKGROUND-It is unclear whether, given a current blood pressure level, the previous 2-year change in blood pressure adds important predictive information for cardiovascular disease (CVD). METHODS AND RESULTS-We conducted a prospective cohort study of 11 150 middle-aged and older men reporting blood pressure in the Physicians' Health Study. These men had no history of CVD or antihypertensive medication use through the time of the 2-year follow-up questionnaire; after this time, follow-up for the current study began. A total of 905 incident cases of CVD (705 cases of coronary heart disease and 200 cases of stroke) occurred during a median follow-up of 10.8 years. After controlling for current blood pressure and other coronary risk factors, we found that previous 2-year changes in systolic blood pressure were not associated with the risk of CVD. A similar lack of association was found for individual end points of coronary heart disease and stroke. However, previous 2-year changes in diastolic blood pressure (DBP) may be inversely associated with the risk of CVD (linear trend, P=0.049) independent of coronary risk factors and current DBP. In subgroup analyses, previous 2-year blood pressure changes only added information in leaner men (body mass index <24.39 kg/m(2)). CONCLUSIONS-In this normotensive population of men, the prior 2-year change in DBP, but not systolic blood pressure, may add information to current levels in relation to the risk of CVD. Clinicians may need to consider the previous pattern of DBP change when considering the risk associated with the current DBP level. These data require confirmation in other studies in which blood pressure is measured.     

Cholesterol fractions and apolipoproteins as risk factors for heart disease mortality in older men

BACKGROUND: The relevance of blood lipid levels as risk factors for ischemic heart disease (IHD) in older people is uncertain; hence, cholesterol-lowering therapy is not routinely prescribed in older populations. METHODS: We assessed IHD mortality associations with plasma levels of total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, apolipoprotein B, and apolipoprotein A(1) measured in older men. Ischemic heart disease was assessed in a 7-year follow-up of a cohort of 5344 men (mean age, 76.9 years), including 74.3% without cardiovascular disease (CVD) or statin use and 25.6% with CVD or statin use. Hazard ratios (HRs) for 447 deaths from IHD were estimated for a 2-SD difference in usual plasma lipid levels. RESULTS: Ischemic heart disease mortality was not significantly associated with total cholesterol levels in all men (HR, 1.05), but a significant positive association in men without CVD and a slight nonsignificant inverse association in men with CVD were observed (HR, 1.47 vs 0.84). The patterns were similar for low-density lipoprotein cholesterol levels (HR, 1.50 vs 0.98) and for apolipoprotein B levels (HR, 1.68 vs 0.93). Ischemic heart disease risks were inversely associated with high-density lipoprotein cholesterol levels and with apolipoprotein A(1) levels in men with and without CVD. Ischemic heart disease risks were strongly associated with total/high-density [corrected] lipoprotein cholesterol levels (HR, 1.57) and apolipoprotein B/apolipoprotien [corrected] A(1) levels (HR, 1.54), and remained strongly related at all ages. CONCLUSIONS: Blood lipid levels other than total cholesterol levels were associated with IHD in older men. Differences in lipid levels that are achievable by statin use were associated with about a one-third lower risk of IHD, irrespective of age.     

Physical Frailty Phenotype and the Development of Geriatric Syndromes in Older Adults with Coronary Heart Disease

BackgroundFrailty, a clinical state of vulnerability, is associated with subsequent adverse geriatric syndromes in the general population. We examined the long-term impact of frailty on geriatric outcomes among older patients with coronary heart disease.MethodsWe used the National Health and Aging Trends Study, a prospective cohort study linked to a Medicare sample. Coronary heart disease was identified by self-report or International Classification of Diseases (ICD) codes 1-year prior to the baseline visit. Frailty was measured using the Fried physical frailty phenotype. Geriatric outcomes were assessed annually during a 6-year follow-up.ResultsOf the 4656 participants, 1213 (26%) had a history of coronary heart disease 1-year prior to their baseline visit. Compared to those without frailty, subjects with frailty were older (ages ≥75: 80.9% vs 68.9%, P < 0.001), more likely to be female, and belong to an ethnic minority. The prevalence of hypertension, stroke, falls, disability, anxiety/depression, and multimorbidity were much higher in the frail, than nonfrail, participants. In a discrete time survival model, the incidence of geriatric syndromes during 6-year follow-up including 1) dementia, 2) loss of independence, 3) activities of daily living disability, 4) instrumental activities of daily living disability, and 5) mobility disability were significantly higher in the frail than in the nonfrail older patients with coronary heart disease.ConclusionIn patients with coronary heart disease, frailty is a risk factor for the accelerated development of geriatric outcomes. Efforts to identify frailty in the context of coronary heart disease are needed, as well as interventions to limit or reverse frailty status for older patients with coronary heart disease.     

Risk factors for coronary disease and stroke in previously hospitalized African-Americans with Type 1 diabetes: a 6-year follow-up.

AIMS: To report the 6-year incidence of, and risk factors for, cardiovascular disease (CVD), either coronary disease or stroke, in previously hospitalized African-Americans with Type 1 diabetes mellitus. METHODS: African-Americans (n = 483) with Type 1 diabetes were re-examined as part of a 6-year follow-up. At both visits, patients underwent a structured clinical interview, which included history of either coronary disease or stroke, ocular examination and masked grading of seven stereoscopic fundus photographs, blood pressure measurements, and administration of the Beck Depression Inventory. Biological measurements included blood and urine assays. RESULTS: Of the 483 patients who had a 6-year follow-up, 449 had no evidence of CVD at the baseline examination. Of these 449 patients, 51 (11.4%) developed any CVD-42 (9.3%) coronary disease and 14 (3.1%) a stroke. Six-year incidence of any CVD was significantly associated with older age (P < 0.0001) and longer duration of diabetes (P < 0.0001) at baseline. Multiple logistic regression showed that baseline older age, higher body mass index, higher diastolic blood pressure, proteinuria, retinopathy severity and being depressed were significant and independent risk factors for incidence of any CVD. CONCLUSION: Six-year incidence of CVD is high in previously hospitalized African-Americans with Type 1 diabetes. Risk factors appear to include older age, higher body mass index, higher diastolic blood pressure, proteinuria, retinopathy severity and depression.     

Ankle-arm index as a predictor of cardiovascular disease and mortality in the Cardiovascular Health Study. The Cardiovascular Health Study Group

Peripheral arterial disease (PAD) in the legs, measured noninvasively by the ankle-arm index (AAI) is associated with clinically manifest cardiovascular disease (CVD) and its risk factors. To determine risk of total mortality, coronary heart disease, or stroke mortality and incident versus recurrent CVD associated with a low AAI, we examined the relationship of the AAI to subsequent CVD events in 5888 older adults with and without CVD. The AAI was measured in 5888 participants >/=65 years old at the baseline examination of the Cardiovascular Health Study. All participants had a detailed assessment of prevalent CVD and were contacted every 6 months for total mortality and CVD events (including CVD mortality, fatal and nonfatal myocardial infarction, congestive heart failure, angina, stroke, and hospitalized PAD). The crude mortality rate at 6 years was highest (32.3%) in those participants with prevalent CVD and a low AAI (P<0.9), and it was lowest in those with neither of these findings (8.7%, P<0.01). Similar patterns emerged from analysis of recurrent CVD and incident CVD. The risk for incident congestive heart failure (relative risk [RR]=1.61) and for total mortality (RR=1.62) in those without CVD at baseline but with a low AAI remained significantly elevated after adjustment for cardiovascular risk factors. Hospitalized PAD events occurred months to years after the AAI was measured, with an adjusted RR of 5.55 (95% CI, 3.08 to 9.98) in those at risk for incident events. A statistically significant decline in survival was seen at each 0.1 decrement in the AAI. An AAI of <0.9 is an independent risk factor for incident CVD, recurrent CVD, and mortality in this group of older adults in the Cardiovascular Health Study.     

Functional Limitations, Socioeconomic Status, and All-Cause Mortality in Moderate Alcohol Drinkers

OBJECTIVES: To determine whether the survival benefit associated with moderate alcohol use remains after accounting for nontraditional risk factors such as socioeconomic status (SES) and functional limitations.
DESIGN: Prospective cohort.
SETTING: The Health and Retirement Study (HRS), a nationally representative study of U.S. adults aged 55 and older.
PARTICIPANTS: Twelve thousand five hundred nineteen participants were enrolled in the 2002 wave of the HRS.
MEASUREMENTS: Participants were asked about their alcohol use, functional limitations (activities of daily living, instrumental activities of daily living, and mobility), SES (education, income, and wealth), psychosocial factors (depressive symptoms, social support, and the importance of religion), age, sex, race and ethnicity, smoking, obesity, and comorbidities. Death by December 31, 2006, was the outcome measure.
RESULTS: Moderate drinkers (1 drink/d) had a markedly more-favorable risk factor profile, with higher SES and fewer functional limitations. After adjusting for demographic factors, moderate drinking (vs no drinking) was strongly associated with less mortality (odds ratio (OR)=0.50, 95% confidence interval (CI)=0.40–0.62). When traditional risk factors (smoking, obesity, and comorbidities) were also adjusted for, the protective effect was slightly attenuated (OR=0.57, 95% CI=0.46–0.72). When all risk factors including functional status and SES were adjusted for, the protective effect was markedly attenuated but still statistically significant (OR=0.72, 95% CI=0.57–0.91).
CONCLUSION: Moderate drinkers have better risk factor profiles than nondrinkers, including higher SES and fewer functional limitations. Although these factors explain much of the survival advantage associated with moderate alcohol use, moderate drinkers maintain their survival advantage even after adjustment for these factors.     

Hearing sensitivity in older adults: associations with cardiovascular risk factors in the health, aging and body composition study

OBJECTIVES: To examine the association between cardiovascular disease (CVD) and its risk factors and age‐associated hearing loss in a cohort of older black and white adults. DESIGN: Cross‐sectional cohort study. SETTING: The Health, Aging, and Body Composition (Health ABC) Study, a community‐based cohort study of older adults from Pittsburgh, Pennsylvania, and Memphis, Tennessee. PARTICIPANTS: Two thousand forty‐nine well‐functioning adults (mean age 77.5; 37% black). MEASUREMENTS: Pure‐tone audiometry measurement and history of clinical CVD were obtained at the fourth annual follow‐up visit. Pure‐tone averages in decibels reflecting low (250, 500, and 1,000 Hz), middle (500, 1,000, and 2,000 Hz), and high (2,000, 4,000, and 8,000 Hz) frequencies were calculated for each ear. CVD risk factors, aortic pulse‐wave velocity (PWV), and ankle–arm index (AAI) were obtained at study baseline. RESULTS: In sex‐stratified models, after adjustment for age, race, study site, and occupational noise exposure, risk factors associated with poorer hearing sensitivity in men included high triglyceride levels, high resting heart rate, and history of smoking. In women, poor hearing sensitivity was associated with high body mass index, high resting heart rate, fast PWV, and low AAI. CONCLUSION: Modifiable risk factors for CVD may play a role in the development of age‐related hearing loss.     

Physical Activity and Executive Function in Aging: The MOBILIZE Boston Study

OBJECTIVES: To determine the relationship between physical activity and cognition, specifically executive function, and the possible mediating role of factors such as cardiovascular disease (CVD) and CVD risk factors, chronic pain, and depressive symptoms.
DESIGN: Cross-sectional study.
SETTING: Population-based study of individuals aged 70 and older in the Boston area.
PARTICIPANTS: Older community-dwelling adults (n=544; mean age 78, 62% female).  

MEASUREMENTS:

Presence of heart disease (self-reported physician diagnosed), pain, and depressive symptomatology were assessed using interviewer-administered questions. Blood pressure was measured. Engagement in physical activity was determined using the Physical Activity Scale for the Elderly (PASE). Cognitive function was measured using a battery of neuropsychological tests.
RESULTS: The older adults who engaged in more physical activity had significantly better performance on all cognitive tests, except for Letter Fluency and the memory test of delayed recall, after adjusting for age, sex, education, and total number of medications. With further adjustment for CVD and CVD risk factors (heart disease, diabetes mellitus, stroke, and hypertension), pain, and depressive symptoms, PASE score remained significantly associated with executive function tests.
CONCLUSION: Even after multivariate adjustment, neuropsychological tests that were executive in nature were positively associated with physical activity participation in this cohort of older community-dwelling adults. In contrast, delayed recall of episodic memory was not associated with physical activity, supporting the idea that the relationship with executive function represents a specific biologically determined relationship.     

Screening and Management of Depression in Patients With Cardiovascular Disease: JACC State-of-the-Art Review

Depression is a common problem in patients with cardiovascular disease (CVD) and is associated with increased mortality, excess disability, greater health care expenditures, and reduced quality of life. Depression is present in 1 of 5 patients with coronary artery disease, peripheral artery disease, and heart failure. Depression complicates the optimal management of CVD by worsening cardiovascular risk factors and decreasing adherence to healthy lifestyles and evidence-based medical therapies. As such, standardized screening pathways for depression in patients with CVD offer the potential for early identification and optimal management of depression to improve health outcomes. Unfortunately, the burden of depression in patients with CVD is under-recognized; as a result, screening and management strategies targeting depression have been poorly implemented in patients with CVD. In this review, the authors discuss a practical approach for the screening and management of depression in patients with CVD.     

Depressive symptoms and risk of functional decline and death in patients with heart failure.

OBJECTIVES: We sought to examine whether depressive symptoms are associated with poorer prognosis in patients with heart failure. BACKGROUND: Depression is an established risk factor for poor outcome in patients with coronary heart disease (CHD). Little is known of its role in patients with heart failure. METHODS: We prospectively followed 391 patients > or =50 years of age who met criteria for decompensated heart failure on hospital admission. The outcome of the study was death or decline in activities of daily living (ADL) at six months, relative to baseline. Depressive symptoms were measured at baseline by means of the Geriatric Depression Scale, Short-Form, with 6 to 7 symptoms, 8 to 10 symptoms and > or =11 symptoms indicating mild, moderate and severe levels of depressive symptoms, respectively. RESULTS: There was a strong and graded association between the severity of depressive symptoms at baseline and the rate of the combined end point of either functional decline or death at six months. After adjustment for demographic factors, medical history, baseline functional status and clinical severity, patients with > or =11 depressive symptoms, compared with those with <6 depressive symptoms, had an 82% higher risk of either functional decline or death, whereas the intermediate levels of depressive symptoms showed intermediate risk (p = 0.003 for trend). A similar graded association was found for functional decline and death separately; however, after multivariate analysis, the association with mortality was less strong and no longer statistically significant. CONCLUSIONS: An increasing number of depressive symptoms is a negative prognostic factor for patients with heart failure, just as it is for patients with CHD.     

Prospective cohort study of hostility and the risk of cardiovascular disease mortality

BACKGROUND: Recent literature reviews have questioned hostility as a risk factor for heart disease. However, controversy persists due to the rarity of large-scale prospective cohort studies of initially healthy populations. METHODS: We prospectively investigated the association between hostility and cardiovascular (and all-cause) mortality among 20,550 men and women, 41-80 years of age, participating in the European Prospective Investigation into Cancer and Nutrition in Norfolk (EPIC-Norfolk), United Kingdom study. Participants were recruited by post from general practice age-sex registers and subsequently attended health checks that included the assessment of coronary disease risk factors. Hostility assessment was completed by postal questionnaire. RESULTS: During mean follow-up of 6 years, 1284 deaths were recorded including 481 from cardiovascular disease (CVD). Hostility was not associated with CVD mortality, after adjustment for age and prevalent disease, in either men (rate ratio for a 1 SD decrease in hostility score, representing increased hostility, 1.09; 95% confidence interval 0.98-1.22) or in women (rate ratio 1.00; 95% confidence interval 0.86-1.26). Subgroup analysis suggested hostility may be associated with CVD mortality (independent of age, prevalent disease and cigarette smoking) for participants reporting very high hostility and for those aged less than 60 years. CONCLUSIONS: Hostility was not associated with an increased risk of cardiovascular mortality in this population study of older adults.     

Obesity is associated with functional decline in community-dwelling rural older persons

OBJECTIVES: This investigation sought to examine potential gender differences in the relationship between body mass index (BMI) and functional decline. DESIGN: Cohort study. SETTING: Rural Pennsylvania. PARTICIPANTS: Medicare managed-risk program participants (aged > or =65) in the Geisinger Health Plan. Mean age at study baseline was 71. Final analyzable sample was 2,634 participants. MEASUREMENTS: Self-reported weight, weight change, living and eating habits, alcohol and medication use, depression, dentition, and functional status were obtained upon enrollment and again between 3 and 4 years later. Measured height and weight were also recorded at enrollment. Functional decline was defined as any increase in reported limitations in activities of daily living or instrumental activities of daily living over the study period. Logistic regression was used to evaluate the relationship between BMI, as defined by current National Institutes of Health categories, and risk of functional decline while controlling for age, depression, and polypharmacy. The referent category was BMI 18.5 to 24.9. RESULTS: Women had a higher prevalence of reported functional decline than men at the upper range of BMI categories (31.4% vs 14.3% for BMI > or =40). Women (odds ratio (OR) = 2.61, 95% confidence interval (CI) = 1.39-4.95) and men (OR = 3.32, 95% CI = 1.29-8.46) exhibited increased risk for any functional decline at BMI of 35 or greater. Weight loss of 10 pounds and weight gain of 20 pounds were also risk factors for any functional decline. CONCLUSIONS: Obesity was a risk factor for functional decline in older persons of either gender. Change in body weight did not benefit function for many older persons.
