Marital status and outcomes in patients with cardiovascular disease

The national burden of cardiovascular disease (CVD) continues to impose significant risk of morbidity, mortality and increased costs. While traditional risk factors have been well-established, the evolving role of non-traditional risk factors, including socioeconomic and psychosocial factors, is increasingly being recognized. Several studies have acknowledged an association between marital status and the presence of CVD and its associated adverse outcomes. Across multiple U.S. and international cohorts, patients who are unmarried, including those who are divorced, separated, widowed, or never married, have an increased rate of adverse cardiovascular events when compared to their married counterparts. Some studies suggest that marriage may have a more protective role for men compared to women. Furthermore, dissatisfaction in a marriage and marriage quality have significant impact on cardiovascular risk. Psychosocial and socioeconomic factors, as well as other acute stressors, may contribute to the association between marital status and CVD outcomes, but the underlying mechanisms are not completely clear. Further investigation is required to identify potential targets for intervention and to determine whether more aggressive targeting of standard anti-atherosclerotic therapies can favorably impact CVD risk in unmarried patients.     

The Role of Novel Biomarkers of Cardiovascular Disease in Chronic Kidney Disease: Focus on Adiponectin and Leptin

Cardiovascular disease (CVD) remains a major cause of premature death in patients with chronic kidney disease (CKD), including renal transplant recipients. Both interplay of traditional cardiovascular and renal specific risk factors have been shown to be associated with an increased risk of cardiovascular death in patients with CKD. Recently, there has been great interest in the role of novel biomarkers, in particular adiponectin and leptin, and its association with CVD in the CKD population. Adiponectin is a multifunctional adipocyte-derived protein with anti-inflammatory, antiatherogenic and insulin sensitizing activity. Recent observational studies have shown adiponectin to be a novel risk marker of CVD in patients with stages 1 to 5 CKD. Leptin is an adipocyte-derived hormone that promotes weight loss by decreasing food intake. Similarly, there are observational studies to support an association between leptin and CVD, including patients with CKD. In the CKD population, leptin may be associated with uremic cachexia and subsequent increased mortality. This review aims to summarize the pathophysiological and potential clinical roles of these cardiovascular biomarkers in patients with CKD.Key Words: Biomarker, cardiovascular disease, adiponectin, leptin, kidney disease.     

Nonalcoholic Fatty Liver Disease: Dyslipidemia,Risk for Cardiovascular Complications,and Treatment Strategy

Studies have shown that nonalcoholic fatty liver disease (NAFLD) is strongly associated with several metabolic disorders and diseases, such as obesity, type 2 diabetes mellitus, and dyslipidemia. In NAFLD, dyslipidemia is manifested as increased serum triglyceride and low-density lipoprotein cholesterol levels and decreased high-density lipoprotein cholesterol levels, all of which are key risk factors for cardiovascular disease (CVD). CVD is a leading cause of mortality in NAFLD patients. Thus, implementation of an aggressive therapeutic strategy for dyslipidemia with hypolipidemic agents may mitigate the risk for CVD among NAFLD patients. Here, we provide a current review of literature regarding NAFLD, with particular emphasis on dyslipidemia and available treatment options.     

Chronic kidney disease and risk of incident myocardial infarction and all-cause and cardiovascular disease mortality in middle-aged men and women from the general population.

AIMS: Chronic kidney disease (CKD) was found to be an independent risk factor for all-cause mortality as well as adverse cardiovascular disease (CVD) events in high-risk populations. Findings from population-based studies are scarce and inconsistent. We investigated the gender-specific association of CKD with all-cause mortality, cardiovascular mortality, and incident myocardial infarction (MI) in a population-based cohort. METHODS AND RESULTS: The study was based on 3860 men and 3674 women (aged 45-74 years) who participated in one of the three MONICA Augsburg surveys between 1984 and 1995. CKD was defined by an estimated glomerular filtration rate between 15 and 59 mL/min/1.73 m(2). Hazard ratios (HRs) were estimated from Cox proportional hazard models. In this study, 890 total deaths, 400 CVD deaths, and 321 incident MIs occurred in men up to 31 December 2002; the corresponding numbers in women were 442, 187, and 102. In multivariable analyses, the HR for women with CKD compared to women with preserved renal function was significant for incident MI [HR 1.67; 95% confidence interval (CI) 1.07-2.61] and CVD mortality (HR 1.60; 95% CI 1.17-2.18). In men, CKD was also significantly associated with incident MI (HR 1.51; 95% CI 1.09-2.10) and CVD mortality (HR 1.48; 95% CI 1.15-1.92) after adjustment for common CVD risk factors. In contrast, men and women with CKD had no significant increased risk of all-cause mortality. CONCLUSION: CKD was strongly associated with an increased risk of incident MI and CVD mortality independent from common cardiovascular risk factors in men and women from the general population.

The cardiometabolic syndrome as a cardiovascular risk factor

The cardiometabolic syndrome (CMS) is associated with cardiovascular disease (CVD) and includes a constellation of risk factors such as central obesity, hypertension, insulin resistance, dyslipidemia, microalbuminuria, and hypercoagulability. Collectively, these risk factors increase CVD endpoints such as stroke, congestive heart failure, chronic kidney disease (CKD), and overall mortality. The CMS is associated with endothelial dysfunction, inflammation, abnormal thrombolysis, and increased oxidative stress that accentuate progression of CVD. We will review how the varying components of the CMS relate to an increased CVD and renal disease risk.     

Severe extra-articular disease manifestations are associated with an increased risk of first ever cardiovascular events in patients with rheumatoid arthritis

BACKGROUND: Rheumatoid arthritis is associated with increased cardiovascular mortality and morbidity. OBJECTIVE: To assess the effect of severe extra-articular rheumatoid arthritis (ExRA) manifestations on the risk of cardiovascular disease (CVD) in patients with rheumatoid arthritis. METHODS: Patients with ExRA (n = 81) according to predefined criteria and controls (n = 184) without evidence of extra-articular disease were identified from a large research database of patients with rheumatoid arthritis. In a structured review of the medical records, the occurrence and the date of onset of clinically diagnosed CVD events were noted. Cox proportional hazards models were used to estimate the effect of ExRA on the risk of first ever CVD events after the diagnosis of rheumatoid arthritis. ExRA manifestations were modelled as time-dependent covariates, with adjustment for age, sex and smoking at the diagnosis of rheumatoid arthritis. Onset of erosive disease and rheumatoid factor seropositivity were entered as time-dependent variables. Patients were followed until onset of CVD, death or loss to follow-up. RESULTS: ExRA was associated with a significantly increased risk of first ever CVD events (p<0.001), and also with an increased risk of new-onset coronary artery disease, adjusted for age, sex and smoking (hazard ratio (HR): 3.16; 95% confidence interval (95% CI: 1.58 to 6.33). The association between ExRA and any first ever CVD event remained significant when controlling for age, sex, smoking, rheumatoid factor and erosive disease (HR: 3.25; 95% CI: 1.59 to 6.64). CONCLUSION: Severe ExRA manifestations are associated with an increased risk of CVD events in patients with rheumatoid arthritis. This association is not due to differences in age, sex, smoking, rheumatoid factor or erosive joint damage. It is suggested that systemic extra-articular disease is a major determinant of cardiovascular morbidity in rheumatoid arthritis.     

The Protective Role of Positive Well-Being in Cardiovascular Disease: Review of Current Evidence,Mechanisms, and Clinical Implications

Positive psychological aspects of well-being—including positive emotions, optimism, and life satisfaction—are increasingly considered to have protective roles for cardiovascular disease (CVD) and longevity. A rapidly-growing body of literature has linked positive well-being with better cardiovascular health, lower incidence of CVD in healthy populations, and reduced risk of adverse outcomes in patients with existing CVD. This review first examines evidence on the associations of positive well-being with CVD and mortality, focusing on recent epidemiological research as well as inconsistent findings. Next, an overview is provided of putative biological, behavioral, and stress-buffering mechanisms that may underlie the relationship between positive well-being and cardiovascular health. Key areas for future inquiry are discussed, in addition to emerging developments that capitalize on technological and methodological advancements. Promising initial results from randomized controlled trials suggest that efforts to target positive well-being may serve as valuable components of broader CVD management programs.     

Team-Based Care of Women With Cardiovascular Disease From Pre-Conception Through Pregnancy and Postpartum: JACC Focus Seminar 1/5

The specialty of cardio-obstetrics has emerged in response to the rising rates of maternal morbidity and mortality related to cardiovascular disease (CVD) during pregnancy. Women of childbearing age with or at risk for CVD should receive appropriate counseling regarding maternal and fetal risks of pregnancy, medical optimization, and contraception advice. A multidisciplinary cardio-obstetrics team should ensure appropriate monitoring during pregnancy, plan for labor and delivery, and ensure close follow-up during the postpartum period when CVD complications remain common. The hemodynamic changes throughout pregnancy and during labor and delivery should be considered with respect to the individual cardiac disease of the patient. The fourth trimester refers to the 12 weeks after delivery and is a key time to address contraception, mental health, cardiovascular risk factors, and identify any potential postpartum complications. Women with adverse pregnancy outcomes are at increased risk of long-term CVD and should receive appropriate education and longitudinal follow-up.     

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.     

NAFLD,and cardiovascular and cardiac diseases: Factors influencing risk,prediction and treatment

Background and aimNon-alcoholic fatty liver disease (NAFLD), affecting up to around 30% of the world’s adult population, causes considerable liver-related and extrahepatic morbidity and mortality. Strong evidence indicates that NAFLD (especially its more severe forms) is associated with a greater risk of all-cause mortality, and the predominant cause of mortality in this patient population is cardiovascular disease (CVD). This narrative review aims to discuss the strong association between NAFLD and increased risk of cardiovascular, cardiac and arrhythmic complications. Also discussed are the putative mechanisms linking NAFLD to CVD and other cardiac/arrhythmic complications, with a brief summary of CVD risk prediction/stratification and management of the increased CVD risk observed in patients with NAFLD.ResultsNAFLD is associated with an increased risk of CVD events and other cardiac complications (left ventricular hypertrophy, valvular calcification, certain arrhythmias) independently of traditional CVD risk factors. The magnitude of risk of CVD and other cardiac/arrhythmic complications parallels the severity of NAFLD (especially liver fibrosis severity). There are most likely multiple underlying mechanisms through which NAFLD may increase risk of CVD and cardiac/arrhythmic complications. Indeed, NAFLD exacerbates hepatic and systemic insulin resistance, promotes atherogenic dyslipidaemia, induces hypertension, and triggers synthesis of proatherogenic, procoagulant and proinflammatory mediators that may contribute to the development of CVD and other cardiac/arrhythmic complications.ConclusionCareful assessment of CVD risk is mandatory in patients with NAFLD for primary prevention of CVD, together with pharmacological treatment for coexisting CVD risk factors.     

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.     

Daytime sleepiness predicts mortality and cardiovascular disease in older adults. The Cardiovascular Health Study Research Group

INTRODUCTION: As part of the baseline examination in the Cardiovascular Health Study, sleep disturbance symptoms including snoring and daytime sleepiness, were assessed as potential risk factors or precipitants of cardiovascular disease (CVD). Because of the association of sleep disturbance with poorer health and the possible associations of sleep apnea with CVD, we hypothesized that those with poorer sleep or daytime sleepiness may be at increased risk of mortality or incident CVD. SETTING: Participants (n = 5888) were recruited in 1989, with an additional minority cohort recruited in 1993, in four US communities for a cohort study designed to evaluate risk factors for cardiovascular disease. METHODS: An interview-administered questionnaire regarding health and sleep habits with ongoing ascertainment of total mortality and cardiovascular disease morbidity and mortality, including total CVD morbidity and mortality, incident myocardial infarction, and congestive heart failure. RESULTS: Daytime sleepiness was the only sleep symptom that was significantly associated with mortality in both men and women. The unadjusted hazard ratio was 2.12 (1.66, 2.72) in women and 1.40 (1.12, 1.73) in men. Men who reported difficulty falling asleep also had an increased mortality rate (HR = 1.43 (1.14, 1.80)) which was not seen in women. The risks were attenuated with adjustment for age but remained significant for daytime sleepiness in women (HR = 1.82 (1.42, 2.34)) and for difficulty falling asleep in men. (HR = 1.29 (1.03, 1.63)). Frequent awakenings, early morning awakening, and snoring were not associated with a significantly increased risk of mortality in these older men and women. Crude event rates were evaluated for total incident cardiovascular morbidity and mortality, incident myocardial infarction, and incident congestive heart failure (CHF). Incident CVD rates were higher in both men and women with daytime sleepiness. The aged adjusted HR was 1.35 (95% CI = 1.03, 1.76) in men and was 1.66 (95% CI = 1.28, 2.16) in women. Incident CVD was not higher in those with any other sleep disturbance including snoring. The risk of CVD events associated with daytime sleepiness was attenuated but remained significant in women after adjustment for age. Incident myocardial infarction (MI) rates were also higher in women with daytime sleepiness but were not significantly higher in men. Incident CHF rates were increased in both men and women with daytime sleepiness. In men, the age adjusted HR was 1.49 (95% CI, 1.12- 1.98) and in women, was 2.21 (95% CI, 1.64-2.98). Women reporting both daytime sleepiness and frequent awakening had a hazard ratio of 2.34 (95% CI, 1.66-3.29) for incident CHF compared with those with daytime sleepiness but without frequent awakening. This interaction was not found in men. CONCLUSIONS: In this study, daytime sleepiness was the only sleep disturbance symptom that was associated with mortality, incident CVD morbidity and mortality, MI, and CHF. These findings were stronger in women than men, i.e., the associations persisted for mortality, CVD, and CHF in women after adjustment for age and other factors. Thus, a report of daytime sleepiness identifies older adults at increased risk for total and cardiovascular mortality, and is an independent risk factor in women.     

Relationship between vitamin D deficiency and cardiovascular disease

Epidemiological studies have found that low 25-hydroxyvitamin D levels may be associated with coronary risk factors and adverse cardiovascular outcomes.Additionally,vitamin D deficiency causes an increase in parathyroid hormone,which increases insulin resistance and is associated with diabetes,hypertension,inflammation,and increased cardiovascular risk.In this review,we analyze the association between vitamin D supplementation and the reduction in cardiovascular disease.The role of vitamin D deficiency in cardiovascular morbidity and mortality is still controversial,and larger scale,randomized placebo controlled trials are needed to investigate whether oral vitamin D supplementation can reduce cardiovascular risk.Given the low cost,safety,and demonstrated benefit of higher 25-hydroxyvitamin D levels,vitamin D supplementation should become a public health priority for combating common and costly chronic cardiovascular diseases.     

Nonalcoholic Fatty Liver Disease and the Heart: JACC State-of-the-Art Review

Nonalcoholic fatty liver disease (NAFLD) and cardiovascular disease (CVD) are both manifestations of end-organ damage of the metabolic syndrome. Through multiple pathophysiological mechanisms, CVD and NAFLD are associated with each other. Systemic inflammation, endothelial dysfunction, hepatic insulin resistance, oxidative stress, and altered lipid metabolism are some of the mechanisms by which NAFLD increases the risk of CVD. Patients with NAFLD develop increased atherosclerosis, cardiomyopathy, and arrhythmia, which clinically result in cardiovascular morbidity and mortality. Defining the mechanisms linking these 2 diseases offers the opportunity to further develop targeted therapies. The aim of this comprehensive review is to examine the association between CVD and NAFLD and discuss the overlapping management approaches.

Depression,Anxiety, and Cognitive Impairment

Purpose of Review

Depression, anxiety, and cognitive impairment constitute established risk markers for incident cardiovascular disease (CVD) and are associated with impaired life expectancy and quality of life and high hospitalization rates and healthcare expenditure. This review summarizes current knowledge about mental health disorders in patients with CVD and heart failure (HF).

Recent Findings

Emerging evidence suggests various shared pathophysiological mechanisms between psychological comorbidities and CVD (e.g., systemic inflammation and autonomic dysfunction). Bi-directional interactions involving the central nervous and cardiovascular systems may help explain the rising prevalence of comorbid mood disorders with increasing CVD severity and support the concept of alternative pathophysiological mechanisms in the presence of severe somatic illness, making symptoms less responsive or unresponsive to psychotropic pharmacotherapy.

Summary

Considering high prevalence and negative impact of psychological comorbidities in CVD and HF, routine care should integrate screening for these conditions. Multidisciplinary treatment approaches with active patient participation in disease management were shown to improve outcomes. However, better understanding of factors mediating the adverse prognostic effects of mood disorders is needed. This might enable more targeted treatment and possibly also facilitate better understanding of the pathophysiological mechanisms driving CVD.

     

Prognostic value of adiponectin for cardiovascular disease and mortality

CONTEXT: Low adiponectin concentrations are associated with the presence of an adverse cardiovascular disease (CVD) risk profile. OBJECTIVE: We studied the predictive value of adiponectin levels for all-cause and CVD mortality and CVD morbidity. DESIGN, SETTING, AND PARTICIPANTS: This was a population-based cohort study in Hoorn, The Netherlands, which started in 1989 and included 2484 participants, aged 50-75 yr. MAIN OUTCOME MEASURES: Hazard ratios (HRs) with 95% confidence interval per sd change in log-adiponectin for all-cause and CVD mortality and CVD morbidity were calculated. RESULTS: Adiponectin was determined for 1077 men and 1248 women. Higher adiponectin reduced the risk of nonfatal CVD in women [HR with 95% confidence interval 0.72 (0.61-0.90) in women and 0.92 (0.79-1.06) in men], but not the risk of all-cause or CVD mortality. In contrast, after adjustment for cardiovascular risk factors, higher adiponectin was a significant predictor of all-cause and CVD mortality [HR for CVD mortality 1.45 (1.10-1.92) in women and 1.30 (1.04-1.63) in men]. Higher adiponectin was associated with an increased risk of CVD mortality in people with prevalent CVD [HR 1.27 (0.98-1.63)] and with reduced risk in people without [HR 0.90 (0.73-1.11)]. After adjustment for cardiovascular risk factors, the HRs for CVD mortality were 1.60 (1.14-2.23) for patients with and 1.38 (1.06-1.80) for patients without prevalent CVD. CONCLUSIONS: High levels of adiponectin predict mortality, in particular in patients with prevalent CVD. We hypothesize that adiponectin protects against metabolic and vascular diseases, but in patients already afflicted with CVD, adiponectin is compensatory up-regulated and, therefore, indicates a high mortality risk.     

Hemostatic abnormalities and relationships to metabolic and hormonal status in polycystic ovarian syndrome

Polycystic ovarian syndrome (PCOS), diagnosed based on hyperandrogenism, ovulatory dysfunction, and polycystic ovaries, is one of the most common disorders of reproductive-aged females. Etiology includes both genetic and environmental/lifestyle factors contributing to both insulin resistance and hyperandrogenism. Clinically, PCOS has reproductive, psychological, and metabolic features, the latter predisposing to cardiovascular disease (CVD). Hemostatic abnormalities have an association with and a demonstrated pathophysiological role in CVD in non-PCOS populations but have not been adequately explored in PCOS. This review focuses on the hemostatic system in PCOS, exploring also relationships to the metabolic and hormonal abnormalities of the syndrome, and aims to identify whether hemostatic abnormalities are present as potential contributors to increased cardiovascular risk. Ultimately, this area may reveal preventative and therapeutic opportunities, which could improve the cardiovascular health of women with PCOS.     

Cardiovascular Disease in Systemic Lupus Erythematosus: The Role of Traditional and Lupus Related Risk Factors

Atherosclerosis is a chronic inflammatory disorder characterized by immune cell activation, inflammation driven plaque formation and subsequent destabilization. In other disorders of an inflammatory nature, the chronic inflammatory state per se has been linked to acceleration of the atherosclerotic process which is underlined by an increased incidence of cardiovascular disease (CVD) in disorders such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA) and antiphopholipid (Hughes) syndrome (APS). SLE is an autoimmune disease that may affect any organ. Premature coronary heart disease has emerged as a major cause of morbidity and mortality in SLE. In addition to mortality, cardiovascular morbidity is also markedly increased in these patients, compared with the general population. The increased cardiovascular risk can be explained only partially by an increased prevalence of classical risk factors for cardiovascular disease; it also appears to be related to inflammation. Inflammation is increasingly being considered central to the pathogenesis of atherosclerosis and an important risk factor for vascular disease. Recent epidemiologic and pathogenesis studies have suggested a great deal in common between the pathogenesis of prototypic autoimmune disease such as SLE and that of atherosclerosis.We will review traditional risk factors for CVD in SLE. We will also discuss the role of inflammation in atherosclerosis, as well as possible treatment strategies in these patients.Key Words: Cardiovascular disease, systemic lupus erythematosus, atherosclerosis.
