Age-related differences in the effect of psychological distress on mortality: Type D personality in younger versus older patients with cardiac arrhythmias

Psychiatric disorders, rumination, and metacognitions in patients with type D personality and coronary heart disease

BACKGROUND

Little is known regarding the prevalence of psychiatric disorders in patients with both coronary heart disease (CHD) and type D personality, and whether these patients may benefit from psychotherapy that modifies metacognitive beliefs implicated in disorder maintenance. This study explored prevalence rates among these patients and associations between type D characteristics, rumination and metacognitions.

METHODS

Forty-seven consecutive patients with CHD who scored positive for type D personality were included in this pre-planned study. Participants underwent structured clinical interviews for mental and personality disorders and completed questionnaires assessing rumination and metacognitions.

RESULTS

Mean age was 53.8 (SD 8.1) years and 21.3% were female. At least one mood disorder or anxiety disorder was found in 70.2% and 61.7% of the patients. The most common disorders were major depressive disorder (59.6%), social phobia (40.4%), and generalized anxiety disorder (29.8%). At least one personality disorder was detected in 42.6%. Only 21% reported ongoing treatment with psychotropic medication whereas none had psychotherapy. Metacognitions and rumination were significantly associated with negative affectivity (0.53-0.72, p < .001) but not social inhibition.

CONCLUSION

Mood and anxiety disorders were highly prevalent and relatively untreated among these patients. Future studies should test the metacognitive model for type D personality.

Risk of recurrent cardiovascular events in coronary artery disease patients with Type D personality

Introduction

Data on the association between Type D personality, its traits negative affectivity (NA) and social inhibition (SI), and risk of major adverse cardiac events (MACE) in coronary outpatients is sparse. Furthermore, the associations between Type D subgroups and cardiovascular risk factors are largely unknown.

Methods

We investigated i) Type D personality, NA and SI and risk of recurrent MACE, and ii) the relationship between Type D subgroups and risk factors in a coronary population. This prospective cohort study included 1083 patients` median 16 months after a myocardial infarction and/or a revascularization procedure who were followed-up for 4.2 (SD 0.4) years. Type D personality was assessed by DS14. Anxiety and depression, statin adherence, and risk factors were assessed by patients' self-report and a clinical examination with blood samples. MACE, defined as cardiovascular death, myocardial infarction, revascularization, stroke or heart failure, were obtained from hospital records from index event to end of study lasting 5.7 years. Data were analyzed by Cox proportional hazard regression.

Results

In all, 352 MACE occurred in 230 patients after average 4.2 years follow-up. Higher NA score was associated with MACE after adjustment for age, risk factors and comorbidity (HR 1.02 per unit increase, 95% CI 1.00-1.05), whereas we found a weaker, not statistically significant estimated effect of higher SI score. After additional adjustment for symptoms of anxiety and depression, we found a weaker, not statistically significant association between NA and MACE (HR 1.01 per unit increase, 95% CI 0.98-1.05). Low statin adherence and smoking were more prevalent in the Type D and high NA group.

Discussion

Our results indicate that the NA trait is related to worse prognosis in outpatients with coronary artery disease.

Type D Personality is Associated With Disease Severity and Poor Quality of Life in Turkish Patients With Fibromyalgia Syndrome: A Cross-Sectional Study

Objectives

This study aims to investigate the rate of type D personality in Turkish patients with fibromyalgia (FM) and evaluate its associations with clinical parameters of FM as well as its effects on health-related quality of life (HRQoL).

Patients and methods

The study included 100 patients with FM (14 males, 86 females; mean age 34.6±7.4 years; range, 22 to 49 years) fulfilling 1990 American College of Rheumatology diagnostic criteria and 50 healthy controls (9 males, 41 females; mean age 32.6±6.5 years; range, 21 to 50 years). Type D personality was assessed using the type D scale-14 (DS-14). FM disease severity was determined by Fibromyalgia Impact Questionnaire (FIQ), functional status by Stanford Health Assessment Questionnaire (HAQ), and HRQoL by Nottingham Health Profile (NHP). Severity of pain and fatigue were measured by visual analog scale (VAS).

Results

The frequency of type D personality was 33% in FM patients and 12% in controls (odds ratio=3.612, 95% confidence interval 1.398-9.333) (p=0.006). Type D FM patients scored higher in tender point count (TPC), FIQ, HAQ, VAS-pain and all NHP subgroups except energy (p<0.01). Type D personality was found to be correlated with FIQ, TPC, HAQ, VAS-pain and NHP subgroups except energy (p<0.01).

Conclusion

Based on our findings, assessment of personality characteristics of patients with FM may hold the key for the treatment of the disease. Besides, a better understanding of personality-related pain in FM patients may provide a more targeted approach to pain treatment.

The association of type D personality and depression with infertility in women

Purpose: Type D personality-defined as the presence of two personality characters, namely negative affectivity (NA) and social inhibition (SI)-is associated with various disorders. The 14-item Type D Scale (DS14), which consists of NA and SI subscales, can be used for the detection of the presence of Type D personality. The aim of our study was to investigate the association of Type D personality and depression with infertility in women.Method: A total of 324 women, 168 primary unexplained infertile women (92 patients undergoing in vitro fertilization (IVF) treatment and 76 undergoing intrauterine insemination (IUI) treatment) and 156 fertile controls were recruited. The 21-item Beck Depression Inventory (BDI-21) and DS14 were completed by all participants. The study was approved by Local Ethics Committee with the protocol number 72867572-050-218.Results: Depression and Type D personality were found to be significantly more prevalent in the infertile group than the fertile group. Type D was positively associated with infertility (OR = 2.34, 95% CI = 1.45-3.78, p < .0001), especially in the younger-aged (<35 years) population (OR = 2.59, 95% CI = 1.48-4.5, p = .001). After adjusting for the duration of marriage, age, obesity, educational level, and the same characteristics of the partner, the association between Type D personality and infertility persisted (OR = 2.56, 95% CI = 1.52-4.29, p < .001). The scores of the BDI-21 and NA subscale were found to be negatively correlated with age and partner's age. The BDI and SI scores, and the NA, SI, and Type D personality rates were similar between the IUI and the IVF groups; however, the NA score was higher, and depression was found to be more prevalent and severe in the IUI group than the IVF group.Conclusions: Type D personality could be positively associated with infertility, especially in younger-aged women.

The risk of developing cardiovascular disease is increased for patients with prostate cancer who are pharmaceutically treated for depression

OBJECTIVE

To examine the associations between pharmaceutically treated anxiety and depression and incident cardiovascular disease (CVD) among 1-year prostate cancer survivors.

PATIENTS AND METHODS

A registry-based cohort study design was used to describe the risk of incident CVD in adult 1-year prostate cancer survivors without a history of CVD. Patients with prostate cancer diagnosed between 1999 and 2011 were selected from the Netherlands Cancer Registry. Drug dispenses were retrieved from the PHARMO Database Network and were used as proxy for CVD, anxiety, and depression. Data were analysed using Cox regression analysis to examine the risk associations between pharmaceutically treated anxiety and depression entered as a time-varying predictor with incident CVD in 1-year prostate cancer survivors, while controlling for age, traditional CVD risk factors, and clinical characteristics.

RESULTS

Of the 5262 prostate cancer survivors, 327 (6%) developed CVD during the 13-year follow-up period. Prostate cancer survivors who were pharmaceutically treated for depression had an increased risk of incident CVD after full adjustment compared to prostate cancer survivors who were not pharmaceutically treated for depression (hazard ratio [HR] 1.51, 95% confidence interval [CI] 1.06-2.15). The increased risk of incident CVD amongst those pharmaceutically treated for depression compared to those who were not pharmaceutically treated for depression, was only valid among: prostate cancer survivors who were aged ≤65 years (HR 2.91; 95% CI 1.52-5.55); those who were not treated with radiotherapy (HR 1.63; 95% CI 1.01-2.65); those who were treated with hormones (HR 1.76; 95% CI 1.09-2.85); those who were not operated upon (HR 1.55; 95% CI 1.07-2.25); and those with tumour stage III (HR 2.21; 95% CI 1.03-4.74) and stage IV (HR 2.47; 95% CI 1.03-5.89).

CONCLUSION

Patients with prostate cancer who were pharmaceutically treated for depression had a 51% increased risk of incident CVD after adjustment for anxiety, age, traditional CVD risk factors, and clinical characteristics. The results emphasise the need to pay attention to (pharmaceutically treated) depressed patients with prostate cancer prior to deciding on prostate cancer treatment and for a timely detection and treatment of CVD.

[Type D personality in patients with coronary heart disease underwent coronary stenting: a prospective study]

AIM

To evaluate the type D personality relation with clinical and instrumental parameters in patients with coronary heart disease (CHD) underwent coronary stenting (CS) and to determine the influence of the personality type D on the prognosis in these patients within one year after CS. Material and methods. Into prospective study we included 977 patients (740 men and 237 women) aged 33 to 86 years (mean age 58.7±9.4) who underwent CS. The Cox proportional hazard regression model was used to estimate the relative risk (RR) with a 95% confidence interval (CI) of the end point. The end points included death from all causes, death from cardiovas- cular disease (CVD), myocardial infarction (fatal + non-fatal) (MI), non-fatal myocardial infarction (non-fatal MI), unstable angina (UA), and stroke. Results. Type D personality was found in 31.8% patients. These did not differ from the others in terms of age, gender, main cardiovascular risk factors. Patients of D-type had tendency to the increase of diabetes diagnosed - 25.1% vs 20.3% (p=0.09). At the same time D-type patients had more prevalent ≥2 myocardial infarction in anamnesis - 9.0% vs 4.5% (p=0,006) among those with post infarction cardiosclerosis. There was no difference between the groups according to echocardiography and the short-term outcomes of CS. During the prospective study period (12±1.8 months) 24 patients (2.4%) died from all causes, 21 patients (2.1%) died from CVD. MI developed in 47 patients (4.8%) of whom, 23 patients (2.4%) underwent non-fatal MI. In 50 patients (5.1%) ischemic heart disease in a prospective period complicated UA. In 8 patients (0.8%) developed a stroke. There was no effect of personality type D on the prognosis in patients with CHD who underwent CS for 1 year after surgery. Conclusion. Among CHD patients underwent CS, type D personality was found in 31.8%. There is no link for type D personality and severity of CHD clinically as well as the short-term and long-term outcomes of CS.

Pharmaceutically treated anxiety but not depression prior to cancer diagnosis predicts the onset of cardiovascular disease among breast cancer survivors

PURPOSE

To examine the associations between pharmaceutically treated anxiety and depression present in the year prior to breast cancer diagnosis and the risk of incident cardiovascular disease (CVD), while controlling for traditional cardiovascular risk factors and clinical characteristics in a population-based observational study.

METHODS

Adult 1-year breast cancer survivors (n = 7227), diagnosed between 01-01-1999 and 12-31-2010, with no history of CVD, were selected from the Netherlands Cancer Registry. Drug dispensing data were derived from the PHARMO Database Network and used as proxy for CVD, anxiety, and depression. By multivariable Cox regression analysis, we examined the risk associated with pharmaceutically treated anxiety and depression for developing CVD after cancer diagnosis, adjusting for age, pharmaceutically treated hypertension, hypercholesterolemia, and diabetes mellitus in the year prior to cancer diagnosis, tumor stage, and cancer treatment.

RESULTS

During the 13-year follow-up period, 193 (3%) breast cancer survivors developed CVD. Women pharmaceutically treated for anxiety in the year prior to their cancer diagnosis had a 48% increased hazard for CVD [HR = 1.48; 95% CI 1.05-1.08] after full adjustment. This association was restricted to breast cancer survivors who were 65 years or younger. Depression was not associated with CVD risk [HR = 0.89; 95% CI 0.52-1.53]. Older age [HR = 1.06; 95% CI 1.05-1.08], hypertension [HR = 1.80; 95% CI 1.32-2.46], and hypercholesterolemia [HR = 1.63; 95% CI 1.15-2.33] were associated with an increased hazard for incident CVD, whereas hormone therapy [HR = 0.59; 95% CI 0.42-0.83] was protective.

CONCLUSIONS

Anxiety present in the year prior to breast cancer diagnosis increases the risk of incident CVD in 1-year breast cancer survivors, after adjustment for depression, traditional cardiovascular risk factors, and clinical characteristics.

Is Type D personality a risk factor for all-cause mortality? A prospective population-based study among 2625 colorectal cancer survivors from the PROFILES registry

Objective Our goal was to examine whether Type D personality and its components, negative affectivity (NA) and social inhibition (SI), were associated with all-cause mortality among colorectal cancer (CRC) patients.

METHODS

CRC patients diagnosed between 2000 and 2009, as registered in the Dutch population-based Eindhoven Cancer Registry, received a questionnaire on Type D (DS14) on average 5.3years after diagnosis. Survival status (31-12-2013) was obtained from the Central Bureau for Genealogy. We used a Cox proportional hazard model to relate personality to all-cause mortality, while adjusting for demographics, clinical characteristics and cardiovascular disease (CVD).

RESULTS

Fifty percent was categorized as the 'reference group' (n=1281), 17% as 'SI only' (n=421), 12% as 'NA only' (n=309), and 21% as 'Type D' (n=532). After adjustment, CRC patients in the 'NA only' and 'Type D' groups showed an increased risk (HR=2.0, 95% CI=1.4-2.8, p<0.01, and HR=1.7, 95% CI=1.3-2.4, p<0.01) for all-cause mortality. This adverse effect of NA was limited to men aged >70. There was an additional adverse effect of SI on all-cause mortality in older men without CVD (HR=2.3, 95% CI=1.2-4.4, p=0.01). Personality was not related to mortality in women. Entering personality continuously, showed an increased risk for NA among older survivors, men and patients with comorbid CVD. Neither SI nor the interaction term was predictive in both the un- and adjusted Cox models.

CONCLUSION

Our findings suggest that it is the NA component that drives the adverse effect of psychological distress on survival in CRC patients, which is most prominent among older men.

Is type D personality an independent risk factor for recurrent myocardial infarction or all-cause mortality in post-acute myocardial infarction patients?

Background Type D personality refers to a combination of simultaneously high levels of negative affectivity and social inhibition. The present study aimed to examine whether type D personality was independently associated with recurrent myocardial infarction or all-cause mortality in post-acute myocardial infarction patients, using any of the previously proposed methods for measuring type D personality. Design This was a prospective cohort study. Methods Utilising data from the Västmanland Myocardial Infarction Study, 946 post-acute myocardial infarction patients having data on the DS14 instrument used to measure type D personality were followed-up for recurrent myocardial infarction and all-cause mortality until 9 December 2015. Data were analysed using Cox regression, adjusted for established risk factors. Results In total, 133 (14.1%) patients suffered from type D personality. During a mean follow-up time for recurrent myocardial infarction of 5.7 (3.2) years, 166 (17.5%) patients were affected by recurrent myocardial infarction, of which 26 (15.7%) had type D personality, while during a mean follow-up time for all-cause mortality of 6.3 (2.9) years, 321 (33.9%) patients died, of which 42 (13.1%) had type D personality. After adjusting for established risk factors, type D personality was not significantly associated with recurrent myocardial infarction or all-cause mortality using any of the previously proposed methods for measuring type D personality. A weak association was found between the social inhibition part of type D personality and a decreased risk of all-cause mortality, but this association was not significant after taking missing data into account in a multiple imputation analysis. Conclusions No support was found for type D personality being independently associated with recurrent myocardial infarction or all-cause mortality in post-acute myocardial infarction patients, using any of the previously proposed methods for measuring type D personality.

Explaining heterogeneity in the predictive value of Type D personality for cardiac events and mortality

BACKGROUND

Type D personality has been associated with adverse outcomes in patients with coronary artery disease (CAD). However, large heterogeneity exists between Type D studies, including some studies reporting null-findings.

OBJECTIVES

The aim of this study was to examine i) choice of endpoint and ii) age as two study characteristics that may partly explain this large heterogeneity in the Type D associated prognostic effect.

METHODS

We used four existing data cohorts of 1503 CAD patients (89% male, mean age=57.2±9.1) with baseline measures of Type D and endpoints >5years follow-up: major adverse cardiac events (MACE), cardiac death/MI, and non-cardiac death. Patients were classified in 4 age categories: <50y, 50-59y, 60-69y and ≥70y. Multiple logistic regression models included age, sex, and clinical covariates.

RESULTS

At follow-up, there were 295 events, including 116 cardiac death/MI, and 37 non-cardiac deaths. Both continuous and categorical measures of Type D predicted adverse events. Type D was independently associated with MACE (OR=1.82; 95%CI 1.33-2.50) and cardiac death/MI (OR=2.49; 95%CI 1.55-3.99). However, Type D was not associated with non-cardiac death (OR=1.23; 95%CI 0.57-2.69). Regarding age, Type D consistently predicted MACE in the lower age groups (all ORs≥2.20, all ps≤.004), but not in patients aged ≥70y (OR=1.43, p=.57).

CONCLUSIONS

Choice of endpoint and age modulated the risk conferred by Type D personality. Type D was associated with an increased risk of cardiac events, but not with non-cardiac death, or with events in patients aged ≥70y. Research on psychosocial risk in CAD should account for different sources of heterogeneity in study characteristics.

Examination of the potential association of stress with morbidity and mortality outcomes in patient with heart failure

Objectives:

The high mortality and morbidity rates associated with heart failure are still not well explained. A few psychosocial factors have been studied and explain some of this risk, but other factors, like stress, remain largely unexplored in heart failure. This study aimed to (1) examine the association of stress with 6-month cardiac event-free survival, (2) examine the relationship of stress with salivary cortisol, and (3) examine the association of salivary cortisol level with 6-month cardiac event-free survival.

Method:

A total of 81 heart failure patients participated. Stress was measured using the brief Perceived Stress Scale. Cortisol was measured from unstimulated whole expectorated saliva. Cox regression analyses were used to determine whether stress predicted event-free survival, and if salivary cortisol predicted event-free survival. Linear and multiple regressions were used to determine the association of stress with salivary cortisol.

Results:

Stress was not a significant predictor of event-free survival in heart failure (heart rate = 1.06; 95% confidence interval = 0.95–1.81; p = 0.32). Salivary cortisol was a significant predictor of event-free survival in the unadjusted model (heart rate = 2.30; 95% confidence interval = 0.99–5.927; p = 0.05), but not in the adjusted model. Stress (β 1.06; 95% confidence interval = 0.95–1.18; p = 0.32) was not a significant predictor of salivary cortisol level.

Conclusion:

Stress is a complex phenomenon, and our measure of stress may not have captured it well. Alternatively, the physical stressors acting in heart failure produce levels of neurohormonal activation that mask the effects of psychosocial stressors or an indirect association of stress with outcomes that is mediated through another construct. Future studies are needed to investigate stress in patients with heart failure to provide definitive answers.
