Blase K, Vermetten E, Lehrer P, Gevirtz R. Neurophysiological Approach by Self-Control of Your Stress-Related Autonomic Nervous System with Depression, Stress and Anxiety Patients. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18073329. [PMID: 33804817 PMCID: PMC8036915 DOI: 10.3390/ijerph18073329] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/22/2021] [Revised: 02/23/2021] [Accepted: 03/08/2021] [Indexed: 01/26/2023]
Abstract
BACKGROUND Heart Rate Variability Biofeedback (HRVB) is a treatment in which patients learn self-regulation of a physiological dysregulated vagal nerve function. While the therapeutic approach of HRVB is promising for a variety of disorders, it has not yet been regularly offered in a mental health treatment setting. AIM To provide a systematic review about the efficacy of HRV-Biofeedback in treatment of anxiety, depression, and stress related disorders. METHOD Systematic review in PubMed and Web of Science in 2020 with terms HRV, biofeedback, Post-Traumatic Stress Disorder (PTSD), depression, panic disorder, and anxiety disorder. Selection, critical appraisal, and description of the Random Controlled Trials (RCT) studies. Combined with recent meta-analyses. RESULTS The search resulted in a total of 881 studies. After critical appraisal, nine RCTs have been selected as well as two other relevant studies. The RCTs with control groups treatment as usual, muscle relaxation training and a "placebo"-biofeedback instrument revealed significant clinical efficacy and better results compared with control conditions, mostly significant. In the depression studies average reduction at the Beck Depression Inventory (BDI) scale was 64% (HRVB plus Treatment as Usual (TAU) versus 25% (control group with TAU) and 30% reduction (HRVB) at the PSQ scale versus 7% (control group with TAU). In the PTSD studies average reduction at the BDI-scale was 53% (HRV plus TAU) versus 24% (control group with TAU) and 22% (HRVB) versus 10% (TAU) with the PTSD Checklist (PCL). In other systematic reviews significant effects have been shown for HRV-Biofeedback in treatment of asthma, coronary artery disease, sleeping disorders, postpartum depression and stress and anxiety. CONCLUSION This systematic review shows significant improvement of the non-invasive HRVB training in stress related disorders like PTSD, depression, and panic disorder, in particular when combined with cognitive behavioral therapy or different TAU. Effects were visible after four weeks of training, but clinical practice in a longer daily self-treatment of eight weeks is more promising. More research to integrate HRVB in treatment of stress related disorders in psychiatry is warranted, as well as research focused on the neurophysiological mechanisms.

Abstract
BACKGROUND Hostility is associated with greater risk for cardiac disease, cardiac events and dysrhythmias. Investigators have reported equivocal findings regarding the association of hostility with acute coronary syndrome (ACS) recurrence and mortality. Given mixed results on the relationship between hostility and cardiovascular outcomes, further research is critical. AIMS The aim of our study was to determine whether hostility was a predictor of ACS recurrence and mortality. METHODS We performed a secondary analysis of data (N = 2321) from a large randomized clinical trial of an intervention designed to reduce pre-hospital delay among patients who were experiencing ACS. Hostility was measured at baseline with the Multiple Adjective Affect Checklist (MAACL) and patients were followed for 24 months for evaluation of ACS recurrence and all-cause mortality. We used Cox proportional hazards modeling to determine whether hostility was predictive of time to ACS recurrence or all-cause mortality. RESULTS The majority of patients were married (73%), Caucasian (97%), men (68%), and had a mean age of 67 ± 11 years. Fifty-seven percent of participants scored as hostile based on the established MAACL cut point (mean score = 7.56 ± 3.8). Hostility was an independent predictor of all-cause mortality (p = < 0.039), but was not a predictor of ACS recurrence (p = 0.792). CONCLUSION Hostility is common in patients with ACS and its relationship to clinical outcomes is important to the design of future interventions to improve long-term ACS mortality.

From Impulse to Action? Cognitive Mechanisms of Impulsivity-Related Risk for Externalizing Behavior. JOURNAL OF ABNORMAL CHILD PSYCHOLOGY 2020; 48:1023-1034.

Abstract
Trait impulsivity is an established risk factor for externalizing behavior problems in adolescence, but little is understood about the cognitive mechanisms involved. Negative automatic thoughts are associated with externalizing behaviors and impulsivity is associated with less cognitive reappraisal. This study sought to adapt the bioSocial Cognitive Theory (bSCT) of impulsivity and substance use (an externalizing behavior) for externalizing behavior in general. It was predicted that only the component of impulsivity characterized by lack of forethought (rash impulsiveness; RI) would be associated with (non-substance use-related) externalizing behaviors, not reward sensitivity/drive. Further, this association would be mediated by negative automatic thoughts. Participants were 404 (226 female, 63%) adolescents from 6 high schools across South-East Queensland (age = 13-17 years, mean age = 14.97 years, SD = 0.65 years) of mostly Australian/New Zealand (76%) or European (11%) descent. Participants completed self-report measures of impulsivity, negative automatic thoughts, and externalizing behaviors. Path analysis revealed that, as predicted, only RI was uniquely associated with negative automatic thoughts and externalizing behaviors. However, only negative automatic thoughts centered around hostility mediated the positive association between RI and externalizing behaviors, with the indirect mediation effect being smaller than the direct association. In contrast to substance use, only one component of impulsivity, RI, was associated with general adolescent externalizing behavior. Hostile automatic thoughts may be an important mechanism of risk, supporting a role for cognitive-behavioral interventions. Other biopsychosocial mechanisms are clearly involved and the bSCT may provide a useful framework to guide future research.

Abstract
OBJECTIVE Psychological traits such as optimism and hostility affect coronary heart disease (CHD) risk, but mechanisms for this association are unclear. We hypothesized that optimism and hostility may affect CHD risk via changes in heart rate variability (HRV). METHODS We conducted a longitudinal analysis using data from the Women's Health Initiative Myocardial Ischemia and Migraine Study. Participants underwent 24-hour ambulatory electrocardiogram monitoring 3 years after enrollment. Optimism (Life Orientation Test-Revised), cynical hostility (Cook-Medley), demographics, and coronary risk factors were assessed at baseline. HRV measures included standard deviation of average N-N intervals (SDNN); standard deviation of average N-N intervals for 5 minutes (SDANN); and average heart rate (HR). CHD was defined as the first occurrence of myocardial infarction, angina, coronary angioplasty, and bypass grafting. Linear and Cox regression models adjusted for CHD risk factors were used to examine, respectively, associations between optimism, hostility, and HRV and between HRV and CHD risk. RESULTS Final analyses included 2655 women. Although optimism was not associated with HRV, hostility was inversely associated with HRV 3 years later (SDANN: adjusted β = -0.54; 95% CI = -0.97 to -0.11; SDNN: -0.49; 95% CI = -0.93 to -0.05). HRV was inversely associated with CHD risk; for each 10-millisecond increase in SDNN or SDANN, there was a decrease in CHD risk of 9% (p = .023) and 12% (p = .006), respectively. CONCLUSIONS HRV did not play a major role in explaining why more optimistic women seem to be somewhat protected from CHD risk. Although hostility was inversely associated with HRV, its role in explaining the association between hostility and CHD risk remains to be established.

Abstract
PURPOSE Heart rate variability biofeedback (HRV-BF) is an effective psychophysiological intervention, with short-term effects of increased autonomic nervous system homeostasis, strengthened baroreflex sensitivity, and decreased hostility in patients with coronary artery disease (CAD). The study examined the 1-year HRV-BF effect on cardiovascular prognosis of these patients. METHODS Of 222 patients with CAD referred by cardiologists, 210 were screened and randomly assigned to the HRV-BF and control groups. All patients received psychophysiological assessment and completed psychological questionnaires at pre- and post-interventions and 1-year follow-up. The cardiovascular prognosis primary endpoints included hospital readmission, emergency revisits, and mortality. RESULTS The HRV-BF group had fewer all-cause readmissions (12.00 vs. 25.42%) and all-cause emergency visits (13.33 vs. 35.59%) than the control group. The low-frequency HRV in the HRV-BF group increased at post-intervention and 1-year follow-up compared with that at pre-intervention. Although no significant interaction effect was found in the standard deviation of the normal-to-normal intervals (F = 2.96, p = 0.055), it increased by 26.68% from pre- to post-intervention and 15.77% from pre-intervention to follow-up in the HRV-BF group. However, it decreased by 3.60% from pre- to post-intervention and increased by 1.99% from pre-intervention to follow-up in the control group. Depression and hostility scores decreased significantly at post-intervention and 1-year follow-up only in the HRV-BF group. CONCLUSIONS The long-term HRV-BF effect was confirmed by improved cardiovascular prognosis, increased cardiac autonomic homeostasis and baroreflex sensitivity, and decreased depression and hostility. HRV-BF is an effective psychophysiological intervention with short- and long-term effects in cardiac rehabilitation programs.

A pilot-study to assess the feasibility and acceptability of an Internet-based cognitive-behavior group therapy using video conference for patients with coronary artery heart disease. PLoS One 2018; 13:e0207931. [PMID: 30496222 PMCID: PMC6264821 DOI: 10.1371/journal.pone.0207931] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2018] [Accepted: 11/08/2018] [Indexed: 12/02/2022] Open
Abstract
Background Many patients with coronary artery heart disease are unable to access traditional psychosocial rehabilitation conducted face to face due to excessive travel distance. Therefore, this study developed and assessed the feasibility and acceptability of an 8-week Internet-based cognitive-behavior group therapy program, described the patterns of use and measured change in risk factors. Methods This study adopted an online video conference system, JointNet, to maintain group interaction functions similar to face to face groups online, and also built an self-learning platform to deliver psychoeducation content and cognitive-behavior therapy related materials and homework. Forty-three out-patients were recruited in the pilot study, who then chose to participate in either the Internet-based cognitive-behavior group therapy or face to face group based on their preference. Fourteen patients were assigned to the waiting-list control. Results Seventeen participants (17/43 = 39.5%) chose the Internet-based cognitive-behavior group therapy program. Among them, thirteen participants (13/17 = 76.5%) finished the program and were more male (92.3% vs. 50%), employed (53.8% vs. 35.3%), and had longer education duration (13.9 vs. 12.5 years) than the counterparts of the face to face group. Furthermore, they were highly motivated with average number of log-ins (66.5 time), website surfing time (950.94 min), reading frequency (78.15 time) and reading time (355.90 min) for the self-learning platform during eight weeks; and also highly satisfied (97%) with visiting the self-learning platform and video conferences. The treatment effectiveness of Internet-based cognitive-behavior group therapy was comparable with face to face one in reducing anxiety, hostility, respiration rate, and in improving vasodilation but not depression compared with the waiting-list control. Conclusion These results indicated that the Internet-based group therapy program using video conference is feasible and acceptable for the psychosocial rehabilitation of patients with coronary artery heart disease, and provides an alternative for patients who are unable to obtain conventional psychosocial rehabilitation conducted face to face.

Abstract
OBJECTIVE This study investigated the importance of the combination of the hostility and defensiveness variables as psychosocial factors that predict the risk of cardiovascular dysfunction. We examined the impact of a stressful situation on blood pressure responses, using a continuous psychophysiological assessment approach. DESIGN We measured the evolution of these responses over three experimental phases (adaptation, task and recovery), also considering a minute-by-minute analysis within each phase. MAIN OUTCOME MEASURES We used the Cook-Medley Hostility Scale and the Social Desirability Questionnaire to form four groups (high hostility and high defensiveness, high hostility and low defensiveness, low hostility and high defensiveness, and low hostility and low defensiveness). RESULTS We expected the group of hostile defensive women to record higher activation (task phase: an academic exam) and slower habituation (recovery phase) compared to the other groups. The results confirmed our hypothesis, as the profile of the hostile defensive individuals was one of constant or sensitization during the task phase, while during the recovery phase those individuals underwent a slow recovery. CONCLUSION Therefore, it can be indicated that the low hostility and low defensive group is the most adaptive, as recorded very little activation in response, and rapid recovery.

Abstract
The aim of this study was to determine the relationships among functional status, hostility, social support, illness perceptions, and health behaviors in patients with coronary artery disease using structural equation modeling. Participants comprised 215 patients with coronary artery disease who had received percutaneous coronary artery intervention or a coronary artery bypass graft in two general hospitals in Seoul, Korea. Using structured interviews with questionnaires, data accrued from July to August, 2015. Fitness of the model was verified with AMOS 21.0. As social support increased, it negatively aligned with cognitive-illness perceptions. Higher levels of hostility and greater negative cognitive-illness perceptions aligned with negative emotional-illness perceptions. Social support indirectly affected emotional-illness perceptions. Lower levels of functional status, greater social support, and more positive cognitive-illness perceptions aligned with health behaviors. Social support indirectly affected health behaviors. In conclusion, nurses should focus on coronary artery disease patients’ physical functions and cognitive-illness perceptions to provide support.

Abstract
OBJECTIVE Evidence from both laboratory and observational studies suggests that acute and chronic smoking leads to reduced high-frequency heart rate variability (HF-HRV), a measure of cardiac vagal regulation. We used ecological momentary assessment (EMA) to study the effect of smoking on concurrent HF-HRV in a trial measuring the effects of hostility reduction and compared 24-hour HF-HRV in smokers and nonsmokers. METHOD Ambulatory electrocardiogram data were collected before randomization from 149 healthy individuals with high hostility levels (20-45 years, body mass index ≤ 32 kg/m) and paired with concurrent EMA ratings of smoking and physical position during waking hours. A multilevel mixed model was estimated associating ln(HF-HRV) from smoking status (between-person factor) and person-centered momentary smoking (within-person factor, treated as a random effect), adjusting for momentary physical position, medication use, and consumption of alcohol and caffeine. RESULTS Thirty-five smokers and 114 nonsmokers provided both EMA and HF-HRV data. Within smokers, ln HF-HRV was reduced by 0.31 millisecond (p = .04) when participants reported having recently smoked cigarettes, compared with when they had not. The 24-hour HF-HRV was significantly lower in smokers (M [SD] = 5.24 [0.14] milliseconds) than nonsmokers (5.63 ± 0.07 milliseconds, p = .01). CONCLUSIONS In healthy smokers with high hostility levels used as their own controls during daily living, smoking acutely reduced HF-HRV. HF-HRV was also reduced in smokers as compared with nonsmokers. Although limited by a small sample of individuals with high hostility levels, these findings nonetheless provide additional evidence that cardiac vagal regulation is lowered by cigarette smoking, which may be one of the numerous pathophysiological effects of smoking.

Abstract
OBJECTIVE Hostility is associated with coronary artery disease. One candidate mechanism may be autonomic nervous system (ANS) dysregulation. In this study, we report the effect of cognitive behavioral treatment on ANS regulation. METHODS Participants were 158 healthy young adults, high in hostility measured by the Cook-Medley Hostility and Spielberger Trait Anger scales. Participants were also interviewed using the Interpersonal Hostility Assessment Technique. They were randomized to a 12-week cognitive behavioral treatment program for reducing hostility or a wait-list control group. The outcome measures were preejection period, low-frequency blood pressure variability, and high-frequency heart rate variability measured at rest and in response to and recovery from cognitive and orthostatic challenge. Linear-mixed models were used to examine group by session and group by session by period interactions while controlling for sex and age. Contrasts of differential group and session effects were used to examine reactivity and recovery from challenge. RESULTS After Bonferroni correction, two-way and three-way interactions failed to achieve significance for preejection period, low-frequency blood pressure variability, or high-frequency heart rate variability (p > .002), indicating that hostility reduction treatment failed to influence ANS indices. CONCLUSIONS Reduction in anger and hostility failed to alter ANS activity at rest or in response to or recovery from challenge. These findings raise questions about whether autonomic dysregulation represents a pathophysiological link between hostility and heart disease.

Abstract
Hostility is a psychosocial risk factor that may decrease heart rate variability (HRV) in coronary artery disease (CAD) through cardiac autonomic imbalance. Heart rate variability biofeedback (HRV-BF) increases HRV indices and baroreflex gain. This study examines the effectiveness of HRV-BF in restoring cardiac autonomic balance and decreasing hostility among patients with CAD. One hundred and fifty-four patients with CAD were assigned randomly to receive 6 weeks of HRV-BF, in addition to the standard medical care received by the wait-list control (WLC) group. A 5-min electrocardiogram, blood pressure, and hostility were assessed pre-intervention, post-intervention, and at 1-month follow-up. The standard deviation of normal-to-normal intervals (SDNN), low frequency (LF), and log LF at post-intervention was significantly higher than that at pre-intervention in the HRV-BF group. Baseline log LF was significantly higher post-intervention and at follow-up after HRV-BF training than at pre-intervention. The treatment curve of log LF pre-session increased significantly after session 2, which was maintained to post-intervention. Expressive hostility, suppressive hostility, and hostility total score at post-intervention and one-month follow-up after HRV-BF were significantly lower than at pre-intervention. This study showed increased HRV and decreased expressive and suppressive hostility behavior in patients with CAD following HRV-BF.

Abstract
OBJECTIVE Hostility is associated with adverse outcomes in patients with coronary heart disease (CHD). However, assessment tools used to evaluate hostility in epidemiological studies vary widely. METHODS We administered nine subscales of the Cook-Medley Hostility Scale (CMHS) to 656 outpatients with stable CHD between 2005 and 2007. We used Cox proportional hazards models to determine the association between each hostility subscales and all-cause mortality. We also performed an item analysis using logistic regression to determine the association between each CMHS item and all-cause mortality. RESULTS There were 136 deaths during 1364 person-years of follow-up. Four of nine CMHS subscales were predictive of mortality in age-adjusted analyses, but only one subscale (the seven-item Williams subscale) was predictive of mortality in multivariable analyses. After adjustment for age, sex, education, smoking, history of heart failure, diabetes, and high-density lipoprotein, each standard deviation increase in the Williams subscale was associated with a 20% increased mortality rate (hazard ratio = 1.20, 95% confidence interval = 1.00-1.43, p = .046), and participants with hostility scores in the highest quartile were twice as likely to die as those in the lowest quartile (hazard ratio = 2.00, 95% confidence interval = 1.10-3.65, p = .023). CONCLUSIONS Among nine variations of the CMHS that we evaluated, a seven-item version of the Williams subscale was the most strongly associated with mortality. Standardizing the assessment of hostility in future epidemiological studies may improve our understanding of the relationship between hostility and mortality in patients with CHD.

Abstract
We introduce an implementation of a novel spline framework for parametrically representing electrocardiogram (ECG) waveforms. This implementation enables a flexible means to study ECG structure in large databases. Our algorithm allows researchers to identify key points in the waveform and optimally locate them in long-term recordings with minimal manual effort, thereby permitting analysis of trends in the points themselves or in metrics derived from their locations. In the work described here we estimate the location of a number of commonly-used characteristic points of the ECG signal, defined as the onsets, peaks, and offsets of the P, QRS, T, and R' waves. The algorithm applies Bayesian optimization to a linear spline representation of the ECG waveform. The location of the knots-which are the endpoints of the piecewise linear segments used in the spline representation of the signal-serve as the estimate of the waveform's characteristic points. We obtained prior information of knot times, amplitudes, and curvature from a large manually-annotated training dataset and used the priors to optimize a Bayesian figure of merit based on estimated knot locations. In cases where morphologies vary or are subject to noise, the algorithm relies more heavily on the estimated priors for its estimate of knot locations. We compared optimized knot locations from our algorithm to two sets of manual annotations on a prospective test data set comprising 200 beats from 20 subjects not in the training set. Mean errors of characteristic point locations were less than four milliseconds, and standard deviations of errors compared favorably against reference values. This framework can easily be adapted to include additional points of interest in the ECG signal or for other biomedical detection problems on quasi-periodic signals.

Abstract
BACKGROUND Hostility is a significant predictor of mortality and cardiovascular events in patients with coronary heart disease (CHD), but the mechanisms that explain this association are not well understood. The purpose of this study was to evaluate potential mechanisms of association between hostility and adverse cardiovascular outcomes. METHODS AND RESULTS We prospectively examined the association between self-reported hostility and secondary events (myocardial infarction, heart failure, stroke, transient ischemic attack, and death) in 1022 outpatients with stable CHD from the Heart and Soul Study. Baseline hostility was assessed using the 8-item Cynical Distrust scale. Cox proportional hazard models were used to determine the extent to which candidate biological and behavioral mediators changed the strength of association between hostility and secondary events. During an average follow-up time of 7.4 ± 2.7 years, the age-adjusted annual rate of secondary events was 9.5% among subjects in the highest quartile of hostility and 5.7% among subjects in the lowest quartile (age-adjusted hazard ratio [HR]: 1.68, 95% confidence interval [CI]: 1.30 to 2.17; P < 0.0001). After adjustment for cardiovascular risk factors, participants with hostility scores in the highest quartile had a 58% greater risk of secondary events than those in the lowest quartile (HR: 1.58, 95% CI: 1.19 to 2.09; P = 0.001). This association was mildly attenuated after adjustment for C-reactive protein (HR: 1.41, 95% CI, 1.06 to 1.87; P = 0.02) and no longer significant after further adjustment for smoking and physical inactivity (HR: 1.25, 95% CI: 0.94 to 1.67; P = 0.13). CONCLUSIONS Hostility was a significant predictor of secondary events in this sample of outpatients with baseline stable CHD. Much of this association was moderated by poor health behaviors, specifically physical inactivity and smoking.

Abstract
OBJECTIVES The aim of this study was to assess differences in health-related quality of life (HRQoL) between Roma and non-Roma coronary heart disease (CHD) patients, and whether differences in hostility contribute to this association. METHODS We examined 570 CHD patients (mean age 57.8, 28.1 % female) scheduled for coronary angiography, 88 (15.4 %) of whom were Roma. Hostility was measured using the 27-item Cook-Medley Scale and HRQoL using the Short-Form Health Survey 36, from which the mental and physical component summary (MCS, PCS) were calculated. The relationship between ethnicity, hostility and HRQoL was examined using regression analyses. RESULTS Roma ethnicity was associated with poorer MCS (B = -3.44; [95 % CI = -6.76; -0.13] and poorer PCS (B = -4.16; [95 % CI = -7.55; -0.78]) when controlled for age, gender and socioeconomic status. Adding hostility to the model weakened the strength of the association between Roma ethnicity and MCS (B = -1.87; [95 % CI = -5.08; 1.35]) but not between Roma ethnicity and PCS (B = -4.07; [95 % CI = -7.50; -0.64]). CONCLUSIONS Roma ethnicity is associated with poorer MCS and PCS. Hostility may mediate the association between Roma ethnicity and MCS. The poorer HRQoL of Roma CHD patients requires attention in both care and research, with special attention on the role of hostility.

J Psychiatr Res 2013; 47:628-35. [PMID: 23434176 PMCID: PMC3594003 DOI: 10.1016/j.jpsychires.2013.01.018] [Citation(s) in RCA: 51] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2012] [Revised: 11/27/2012] [Accepted: 01/18/2013] [Indexed: 12/13/2022]
Abstract
Cardiac vagal control (CVC), an index of parasympathetic contribution to cardiac regulation, has been linked to enhanced executive functioning (EF). However, findings to date have been based on small or unique samples. Additionally, previous studies assessed the CVC-EF link only during rest or recovery period from a cognitive challenge, but not during both states. In the present study, data on 817 socioeconomically diverse participants were obtained from the Midlife Development in the United States (MIDUS) study. As part of this study, participants completed cognitive tests, including EF, along with laboratory-based measures of CVC during rest and following recovery from a cognitive challenge. Regression analyses adjusting for respiratory rate revealed no effect of CVC at rest or during recovery on a global index of EF. However, exploratory post-hoc analyses of the components of the global EF index revealed a significant association between faster vagal recovery and better attention-switching and response inhibition abilities, as indexed by faster reaction time to the mixed SGST. This association remained significant after controlling for demographic, clinical (BMI, diseases and medications altering cardiac autonomic functioning, etc.), and health behavior covariates (Beta = .148, p = .010). Our findings suggest that future studies may need to investigate the links of CVC to specific EF abilities, rather than global measures of EF. Additionally, our results highlight the importance of assessing CVC during both rest and recovery from a cognitive challenge. The authors discuss the putative neurobiological underpinning of this link, as well as suggestions for future basic and clinical research.

Abstract
In the popular imagination, anger has long been linked to cardiovascular diseases (CVD), but empirical validation from case-control and prospective studies emerged only in the 1970's. After describing the multidimensional nature of anger and its assessment (via self-report or observed in structured interviews), this paper selectively reviews evidence in (a) behavioral epidemiology, (b) stress and biological processes with implications for cardiopathogenesis, and (c) behavioral/pharmacological interventions for anger/hostility reduction. Although evidence is inconsistent, chronic feelings of anger, cynical distrust and antagonistic behavior are at least modestly associated with risk of both initiation and progression of CVD. Anger/hostility also is linked to stress exposure and reactivity, exaggerated autonomic function, reduced heart rate variability, platelet aggregation and inflammation. Clinical and pharmacologic treatment of anger/hostility has the potential to reduce anger and its health-damaging effects. Limitations, including third-variable explanations and overlap among the negative emotions, and implications for cardiology and behavioral medicine research and practice are discussed.

Abstract
Hostility is associated with a number of metabolic risk factors for cardiovascular disease, including waist-hip ratio, glucose, and triglycerides. Along with hostility, many of these measures have also been shown to be associated with reduced central serotonergic function. We have previously reported that a citalopram intervention was successful in reducing hostility by self-report assessment (Kamarck et al., 2009). Here we examine the effects of this serotonergic intervention on metabolic risk factors in the same sample. 159 healthy adults with elevated hostility scores were randomized to citalopram or placebo for a 2-month period. Citalopram favorably changed metabolic risk factors, including waist circumference (p=.003), glucose (p=.02), HDL cholesterol (p=.04), triglycerides (p=.03), insulin sensitivity (p=.045) and diastolic blood pressure by automated assessment (p=.0021). All of these metabolic changes were significantly mediated by treatment-related changes in body mass index (in most cases, p<.01). In addition, the changes in blood glucose were significantly mediated by treatment-related changes in hostility (p<.05). Mechanisms accounting for these associations remain to be explored.
