Anxiety and Risk of Incident Coronary Heart Disease:A Meta-Analysis

ObjectivesThe purpose of this study was to assess the association between anxiety and risk of coronary heart disease (CHD).BackgroundLess research has focused on the association of anxiety with incident CHD in contrast to other negative emotions, such as depression.MethodsA meta-analysis of references derived from PubMed, EMBASE, and PsycINFO (1980 to May 2009) was performed without language restrictions. End points were cardiac death, myocardial infarction (MI), and cardiac events. The authors selected prospective studies of (nonpsychiatric) cohorts of initially healthy persons in which anxiety was assessed at baseline.ResultsTwenty studies reporting on incident CHD comprised 249,846 persons with a mean follow-up period of 11.2 years. Anxious persons were at risk of CHD (hazard ratio [HR] random: 1.26; 95% confidence interval [CI]: 1.15 to 1.38; p < 0.0001) and cardiac death (HR: 1.48; 95% CI: 1.14 to 1.92; p = 0.003), independent of demographic variables, biological risk factors, and health behaviors. There was a nonsignificant trend for an association between anxiety and nonfatal MI (HR: 1.43; 95% CI: 0.85 to 2.40; p = 0.180). Subgroup analyses did not show any significant differences regarding study characteristics, with significant associations for different types of anxiety, short- and long-term follow-up, and both men and women.ConclusionsAnxiety seemed to be an independent risk factor for incident CHD and cardiac mortality. Future research should examine the association between anxiety and CHD with valid and reliable anxiety measures and focus on the mechanisms through which anxiety might affect CHD

Heritability of type-D personality.

OBJECTIVE: To quantify the influence of genes and environment on individual differences in type-D status, and the type-D subcomponents negative affectivity and social inhibition. Type-D personality independently predicts poor prognosis in patients with cardiovascular disease. However, no previous study has determined the heritability of type-D personality. METHODS: This study determined type-D personality by applying the "combination of scales" method to survey data collected by the Netherlands Twin Register in 3331 healthy, young adult twins. Using structural equation modeling (SEM), the relative contributions of additive genetic, nonadditive genetic, and nonshared environmental factors to the variance in type-D and its subcomponents were determined. RESULTS: SEM indicated that type-D personality was substantially heritable (52%). The subcomponents negative affectivity and social inhibition were equally heritable, with broad heritability estimates of 46% and 50%. Although negative affectivity was determined by additive genetic effects and nonshared environment, individual differences in social inhibition were predominantly determined by nonadditive genetic effects and nonshared environment. CONCLUSIONS: This study provides strong evidence that genes are important in determining individual differences in type-D personality and the type-D subcomponents negative affectivity and social inhibition.

Validity of Type D personality in Iceland: association with disease severity and risk markers in cardiac patients

Type D personality has been associated with poor prognosis in cardiac patients. This study investigated the validity of the Type D construct in Iceland and its association with disease severity and health-related risk markers in cardiac patients. A sample of 1,452 cardiac patients completed the Type D scale (DS14), and a subgroup of 161 patients completed measurements for the five-factor model of personality, emotional control, anxiety, depression, stress and lifestyle factors. The Icelandic DS14 had good psychometric properties and its construct validity was confirmed. Prevalence of Type D was 26–29%, and assessment of Type D personality was not confounded by severity of underlying coronary artery disease. Regarding risk markers, Type D patients reported more psychopharmacological medication use and smoking, but frequency of previous mental problems was similar across groups. Type D is a valid personality construct in Iceland, and is associated with health-related risk markers, but not cardiac disease severity

Anhedonia is associated with poor health status and more somatic and cognitive symptoms in patients with coronary artery disease

Purpose: The effectiveness of cardiac rehabilitation (CR) in patients with coronary artery disease (CAD) is moderated by negative emotions and clinical factors, but no studies evaluated the role of positive emotions. This study examined whether anhedonia (i.e. the lack of positive affect) moderated the effectiveness of CR on health status and somatic and cognitive symptoms. Methods: CAD patients (n = 368) filled out the Hospital Anxiety and Depression Scale (HADS) to assess anhedonia at the start of CR, and the Short-Form Health Survey (SF-36) and the Health Complaints Scale (HCS) at the start of CR and at 3 months to assess health status and somatic and cognitive symptoms, respectively. Results: Adjusting for clinical and demographic factors, health status improved significantly during the follow-up (F(1,357) = 10.84, P = .001). Anhedonic patients reported poorer health status compared with non-anhedoni

Symptom Dimensions of Anxiety Following Myocardial Infarction:Associations With Depressive Symptoms and Prognosis

Objective: Differential associations of symptom dimensions with prognosis in myocardial infarction (MI) patients have been shown for depression, but no studies have focused on anxiety dimensions. The aim of this study was to assess the association between somatic and psychological symptoms of anxiety following acute MI with adverse prognosis and to assess the overlap between anxiety and depression dimensions. Method: Patients (n = 418) were assessed on demographic and clinical variables. The Hamilton Anxiety and Depression Rating Scales were used to measure anxiety and depression 2 months post-MI. Mean follow-up period was 3.8 years and the endpoint consisted of all-cause mortality and recurrent MI. Results: After adjustment for demographic and clinical variables, somatic anxiety was significantly associated with recurrent MI and mortality (HR: 1.32; 95% CI [1.03, 1.69]; p = .03), and a trend was shown for an association between psychological anxiety and outcome (HR: 1.29; 95% CI [0.99, 1.67]; p = .06). The total anxiety score of the HARS was the strongest predictor of recurrent MI and mortality (HR: 1.38; 95% CI [1.07, 1.78]; p = .02). The HARS and the HDRS were highly correlated (r = .86; p < .01). Dimensions consisting of psychological distress (HR: 1.29; 95% CI [1.02, 1.63]; p = .03) and cardiopulmonary/autonomic symptoms (HR: 1.36; 95% CI [1.06, 1.75]; p = .02) also predicted outcome in adjusted analyses. Conclusions: Anxiety was associated with adverse prognosis in MI patients with significant associations for somatic anxiety and total anxiety. When combining anxiety and depression items, psychological distress and cardiopulmonary/autonomic symptoms predicted recurrent MI and mortality. Future research might better focus on dimensions of anxiety and depression simultaneously in MI patients

Personality, psychological stress, and self-reported influenza symptomatology

<p>Abstract</p> <p>Background</p> <p>Psychological stress and negative mood have been related to increased vulnerability to influenza-like illness (ILI). This prospective study re-evaluated the predictive value of perceived stress for self-reported ILI. We additionally explored the role of the negative affectivity and social inhibition traits.</p> <p>Methods</p> <p>In this study, 5,404 respondents from the general population were assessed in terms of perceived stress, personality, and control variables (vaccination, vitamin use, exercise, etc.). ILI were registered weekly using self-report measures during a follow-up period of four weeks.</p> <p>Results</p> <p>Multivariable logistic regression analysis on ILI was performed to test the predictive power of stress and personality. In this model, negative affectivity (OR = 1.05, p = 0.009), social inhibition (OR = 0.97, p = 0.011), and perceived stress (OR = 1.03, p = 0.048) predicted ILI reporting. Having a history of asthma (OR = 2.33, p = < 0.0001) was also associated with ILI reporting. Older age was associated with less self-reported ILI (OR = 0.98, P = 0.017).</p> <p>Conclusion</p> <p>Elderly and socially inhibited persons tend to report less ILI as compared to their younger and less socially inhibited counterparts. In contrast, asthma, trait negative affectivity, and perceived stress were associated with higher self-report of ILI. Our results demonstrate the importance of including trait markers in future studies examining the relation between stress and self-report symptom measures.</p
