Poor health-related quality of life in patients with peripheral arterial disease: Type D personality and severity of peripheral arterial disease as independent predictors

Relationship between Type D personality and adverse health outcomes in people with type 2 diabetes: The parallel mediating roles of diabetes distress and social isolation

AIM

To investigate the relationship between Type D personality and adverse health outcomes [glycated haemoglobin (HbA1c) and health-related quality of life (HRQOL)] directly, and indirectly via diabetes distress and social isolation in people with type 2 diabetes.

DESIGN

A secondary analysis of 524 participant's data derived from a cross-sectional, correlational study with people with type 2 diabetes.

METHODS

Data were analysed using the PROCESS macro of SPSS.

RESULTS

Type D personality was present in 31.3% of the participants, and exerted a direct effect on HRQOL but not on HbA1c. Type D personality indirectly affected both HbA1c and HRQOL via the mediators of diabetes distress and social isolation. Nurses need to monitor people with type 2 diabetes to determine whether Type D personality is present. Those with Type D personality should be provided with interventions to reduce diabetes distress and alleviate social isolation in order to improve HbA1c and HRQOL.

The negative affectivity dimension of Type D personality associated with increased risk for acute ischemic stroke and white matter hyperintensity

OBJECTIVE

This study was conducted to examine the relationship among type D personality, acute ischemic stroke (AIS), and white matter hyperintensity (WMH).

METHODS

In a cross-sectional study conducted between September 2020 and June 2021, 235 patients aged 50-85 years with first-ever ischemic cerebrovascular disease, including 146 males and 89 females, were enrolled. All participants underwent the Type D Scale-14 test containing negative affectivity (NA) and social inhibition (SI) subscales. Clinical and laboratory data were also collected for analysis. The patients were divided into the AIS group (n = 148) and the transient ischemic attack (TIA) group (n = 87) according to whether there was an acute lesion.

RESULTS

Patients with type D personality had a higher frequency of AIS and LAA and a higher level of WMH. Multiple logistic regression showed that the NA score was related to a 1.11-fold increase in the odds of AIS (95% CI: 1.03-1.19). Neither NA nor SI showed a clear association with a higher frequency of LAA. Higher scores of NA (OR = 1.07, 95% CI: 1.01-1.15), SI (OR = 1.11, 95% CI: 1.03-1.19), and the interaction between the two dimensions (OR = 1.03, 95% CI: 1.01-1.05) were independently associated with an increased load of WMH.

CONCLUSION

Type D personality was related to AIS and WMH. In particular, it was NA, not SI, affected the occurrence of AIS. Our findings may provide new insights regarding behavioral vulnerability for the development of cerebrovascular disorders.

An Unsafe/Safe Typology in People with Type 2 Diabetes: Bridging Patients' Expectations, Personality Traits, Medication Adherence, and Clinical Outcomes

BACKGROUND

Support programs are provided to people with diabetes to help them manage their disease. However, adherence to and persistence in support programs are often low, making it difficult to demonstrate their effectiveness.

AIM

To identify the determinants of patients' perceived interest in diabetes support programs because it may be a powerful determinant of effective participation in such programs.

PATIENTS AND METHODS

An online study conducted in April 2021 in metropolitan France on 600 people with diabetes recruited from a consumer panel. A 64-item psychosocial questionnaire including a question asking to evaluate the helpfulness of a support program was used. Univariate, multivariate, and multiple correspondence analyses were performed.

RESULTS

The existence of a typology, known as Unsafe/Safe, was discovered, in which patients with type 2 diabetes respond in two distinct ways. Type U (unsafe) patients, who believe that a support program would be helpful, are more likely to be nonadherent to their treatment, have high hemoglobin A1c levels, have at least one diabetic complication, lack information regarding their disease and treatment, rate the burden of their disease and impairment of their quality of life as high, worry about their future, and are pessimistic. Type S (safe) patients have the opposite characteristics. Type U patients can be dichotomized into two broad classes: one in which they lack information regarding disease and treatment and the other in which alterations in the quality of life and burden of the disease predominate. Insulin-treated patients give more importance to the lack of information, whereas noninsulin-treated patients complain primarily about the burden of the disease and impairment of quality of life.

CONCLUSION

This study describes this new U/S typology, proposes a simple method based on a nine-item questionnaire to identify type U patients by calculating a Program Helpfulness Score described herein, and clarifies the nature of the intervention to be provided to them. This novel approach could be applied to other chronic diseases.

Continuous peripheral nerve block for in-patients with lower limb ischemic pain

OBJECTIVES

Demonstrate that continuous peripheral nerve block (CPNB) may be an alternative with adequate analgesia and a lower incidence of side effects for ischemic pain due peripheral obstructive arterial disease (POAD).

METHODS

Retrospective cohort study with 21 patients with POAD, Fontaine IV graded, with foot pain. Patients were submitted to continuous sciatic nerve block (CSNB), through a perineural catheter. Primary outcomes were pain intensity (by numerical rating scale) and opioid consumption (in oral morphine equivalents).

RESULTS

During CSNB, pain scores markedly decreased in comparison to the pre-block period.

CONCLUSIONS

CPNB may be a good option for ischemic pain treatment in in-patients, as it provides effective pain control with fewer adverse effects.

The mediating effect of resilience on the relationship between Type D personality and self-care behavior in patients with heart failure

AIM

There have been few studies done looking at the relationship between resilience, Type D personality, and self-care behavior in patients with heart failure. The purpose of this study was to identify the mediating effect of resilience on the relationship between Type D personality and self-care behavior in patients with heart failure.

METHODS

The subjects consisted of a sample of 90 heart failure patients aged ≥20 years who visited the cardiology outpatient clinic in the Chungbuk area of South Korea.

RESULTS

Among 90 patients, 49 subjects (54.0%) were classified as Type D personality, who exhibited statistically significant differences in resilience and self-care behavior (p < .001). A statistically significant correlation was also observed between self-care behavior score and resilience score (p < .01). The resilience had full mediation effects on the relationship between Type D personality and self-care behavior. In other words, the higher their resilience, the better their self-care behavior.

CONCLUSIONS

The study showed that resilience and Type D personality have important effects on self-care behavior.

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.

Type D Personality and Health-Related Quality of Life in Vascular Surgery Patients

BACKGROUND

This study evaluated the association of type D personality and health-related quality of life (HRQoL) and assessed the stability of type D personality in vascular surgery patients during the year after surgery.

METHOD

In a prospective cohort study between 2008 and 2014, 294 patients were assessed with validated questionnaires preoperatively and at 1, 6, and 12 months after surgery. Associations between type D personality, depression, and HRQoL were analyzed by generalized estimating equation models. Type D personality was analyzed in its standard dichotomous form as well as continuous (z) scores of its two components, negative affectivity (NA) and social inhibition (SI), and their interaction term.

RESULTS

Prevalence of type D personality varied between 18% and 25%. However, only 9% of the complete responders were classified as type D personality at all four assessments, whereas one third changed between type D classifications. Continuous scores showed greater stability over time. Dichotomized type D personality measured over time was significantly associated with impaired HRQoL, but this was not the case if measured once at baseline, like in general use. The continuous NA score and depression were also significantly associated with impaired HRQoL over time.

CONCLUSION

Type D personality was not a stable trait over time. Preoperative assessment of type D personality did not predict improvement in HRQoL after vascular surgery. However, the study revealed associations between the NA component of type D personality, depression, and lower HRQoL. This indicates that measures of overall negative affect should be taken into account when assessing HRQoL patient-reported outcomes in vascular surgery patients.

Factors Associated With Failure of Adult Strabismus-20 Questionnaire Scores to Improve Following Strabismus Surgery

Importance

Health-related quality of life (HRQOL) typically improves following strabismus surgery. Nevertheless, for some patients, HRQOL does not improve, and reasons for this are unknown.

Objective

To identify factors associated with failure of adult strabismus-20 (AS-20) HRQOL scores to improve following strabismus surgery.

Design, Setting, and Participants

Prospective observational case series at the Mayo Clinic, Rochester, Minnesota, comprising 276 adults, between July 2012 and August 2016.

Main Outcomes and Measures

Participants completed the AS-20 HRQOL questionnaire, diplopia questionnaire, Center for Epidemiologic Studies Depression Scale-Revised (CESD-R) (depressive symptoms), and Type-D Scale 14 questionnaire (type-Distressed [type-D] personality) both preoperatively and 6 weeks postoperatively. To assess factors associated with failure of HRQOL to improve (no change or decrease in score), univariate and multiple logistic regression analyses were performed. Each of the 4 AS-20 domains (self-perception, interactions, reading function, and general function) were analyzed separately including only patients able to improve at least by the magnitude of previously defined 95% limits of agreement. Factors assessed were age (at onset and at surgery), sex, number of previous surgeries, presence of visually obtrusive facial anomaly, visual acuity, preoperative and postoperative diplopia questionnaire scores, alignment (as a vector), presence of esotropia, presence of a vertical deviation, CESD-R scores, and type-D personality. Stepwise multiple logistic regression analyses were performed to assess factors associated with failure of AS-20 scores to improve for each domain.

Results

Of the 276 participants, the median age was 57 years (range, 18-91 years), 153 were women (55%), and 266 were white (96%). Failure to improve was associated with worse diplopia postoperatively on the self-perception (adjusted risk ratio [RR], 1.01; 95% CI, 1.00-1.02), reading function (adjusted RR, 1.02; 95% CI, 1.01-1.03), and general function domains (adjusted RR, 1.02; 95% CI, 1.01-1.03). In addition, failure to improve on the self-perception domain was associated with type-D personality postoperatively (adjusted RR, 4.26; 95% CI, 1.90-9.57) and failure to improve on the interactions domain was associated with postoperative depressive symptoms (adjusted RR, 1.04; 95% CI, 1.02-1.06) and coexisting visually obtrusive anomaly (adjusted RR, 2.12; 95% CI, 1.04-4.32).

Conclusions and Relevance

Postoperative diplopia, depressive symptoms, type-D personality, and visually obtrusive facial anomalies were associated with failure of AS-20 scores to improve (remaining the same or worsening) following strabismus surgery. The association of nonstrabismus factors may have implications for patient treatment and is worthy of continued study.

A Qualitative Study Exploring Patient Concerns and Values in Chronic Limb-Threatening Ischemia

BACKGROUND

Chronic limb-threatening ischemia (CLTI) is the debilitating end stage of peripheral artery disease, causing patients to experience low quality of life and poor health outcomes. It is unknown which aspects of care patients with CLTI value. This pilot qualitative study aims to explore patients' concerns and values related to CLTI treatment, to better inform patient-centered care.

METHODS

A qualitative study design was piloted to explore the experiences of patients with CLTI undergoing elective vascular surgery. In-depth, semistructured interviews were recorded preoperatively and 3 mo after discharge. Transcribed interviews were analyzed using content analysis, to derive patient-centered themes. Findings were mapped to a framework of patient-centered care.

RESULTS

Twelve interviews from six participants were analyzed. Five themes related to participant experiences of CLTI were identified: treatment and diagnosis, concerns about symptoms, limitations in physical function, social function, and emotional function. Participants expressed how CLTI intruded on all aspects of their lives. Framework analysis demonstrated CLTI patients valued patient-centered care relating to both relational and functional aspects of care. In particular, participants valued supportive and trustworthy care, in addition to integrated, holistic care that recognized the patient in the context of their overall health and life.

CONCLUSIONS

Feasibility was demonstrated for both study design and methodology. Data obtained from interviews were sufficiently "rich and thick" in quality and quantity to allow for common themes related to experience and health care values in patients with CLTI to be identified. If confirmed in future studies, these findings will enhance patient-centered care in CLTI.

Predictors of health-related quality of life in patients with symptomatic peripheral artery disease

OBJECTIVE

The aim of this study was to identify predictors of baseline measures of health-related quality of life (HRQoL) in symptomatic patients with peripheral artery disease (PAD) from objective markers of severity of PAD, clinical and demographic characteristics, comorbid conditions, cardiovascular risk factors, objectively measured physical activity, and patient-based measures of physical function.

METHODS

HRQoL measurements of 216 symptomatic men and women with PAD were assessed with the Medical Outcomes Study 36-Item Short Form Health Survey. Patients were further characterized on demographic variables, comorbid conditions, cardiovascular risk factors, ankle-brachial index, peak walking time during a maximal treadmill test, 6-minute walk distance, gait speed, ambulatory activity monitored during 1 week, activities of daily living (ADLs), Mini-Mental State Examination questionnaire, and Walking Impairment Questionnaire (WIQ).

RESULTS

For the physical function HRQoL subscale, the significant predictors included WIQ speed score (P < .001), history of stumbling (P < .001), WIQ stair climbing score (P < .001), ADL associated with bathing (P = .001), 6-minute walk distance (P = .004), and daily walking cadence (P = .043). For the role emotional function HRQoL subscale, the significant predictors included a history of stumbling (P < .001), the ADL associated with transferring from a bed to a chair (P < .001), and the WIQ distance score (P = .022).

CONCLUSIONS

Physical and mental subscales of HRQoL in symptomatic patients with PAD are primarily predicted by patient-based physical function rather than by more specific markers of PAD severity and comorbid conditions. The clinical significance is that interventions designed to improve HRQoL should focus on improving the quality of executing functional tasks, such as walking more steadily without stumbling; completing ADLs that are not specific to walking, such as bathing and transferring; and improving patient-based ability to walk various distances and speeds and to climb stairs.

Does personality affect health-related quality of life? A systematic review

Background

Health-related quality of life (HRQOL) is increasingly measured as an outcome for clinical and health services research. However, relatively little is known about how non-health factors affect HRQOL. Personality is a potentially important factor, yet evidence regarding the effects of personality on HRQOL measures is unclear.

Methods

This systematic review examined the relationships among aspects of personality and HRQOL. Eligible studies were identified from Medline and PsycINFO. The review included 76 English-language studies with HRQOL as a primary outcome and that assessed personality from the psychological perspective. Individuals with various health states, including ill (e.g., cancer, cardiovascular disorders), aging, and healthy, were included in this review study.

Results

Some personality characteristics were consistently related to psychosocial aspects more often than physical aspects of HRQOL. Personality characteristics, especially neuroticism, mastery, optimism, and sense of coherence were most likely to be associated with psychosocial HRQOL. Personality explained varying proportions of variance in different domains of HRQOL. The range of variance explained in psychosocial HRQOL was 0 to 45% and the range of explained variance in physical HRQOL was 0 to 39%.

Conclusions

Personality characteristics are related to HRQOL. Systematic collection and analysis of personality data alongside HRQOL measures may be helpful in medical research, clinical practice, and health policy evaluation.

An integrative review of health-related quality of life in patients with critical limb ischaemia

AIMS AND OBJECTIVES

To examine the domains and the domain-specific characteristics within a peripheral arterial disease health-related quality of life framework for their usefulness in defining critical limb ischaemia health-related quality of life.

BACKGROUND

Critical Limb Ischaemia presents a highly individualised set of personal and health circumstances. Treatment options include conservative management, revascularisation or amputation. However, the links between treatment decisions and quality of life require further investigation.

DESIGN

The framework for this integrative review was the peripheral arterial disease-specific health-related quality of life domains identified by Treat-Jacobson et al.

RESULTS

The literature expanded and refined Treat-Jacobson's framework by modifying the characteristics to better describe health-related quality of life in critical limb ischaemia.

CONCLUSIONS

Given that critical limb ischaemia is a highly individualised situation with powerful health-related quality of life implications, further research focusing on patient and family-centred decision-making relating to therapeutic options and advanced care planning is required.

RELEVANCE TO CLINICAL PRACTICE

A critical limb ischaemia-specific, health-related quality of life tool is required to capture both the unique characteristics of this disorder, and the outcomes for active or conservative care among this complex group of patients.

The role of personality in the course of health-related quality of life and disease-specific health status among colorectal cancer survivors: A prospective population-based study from the PROFILES registry

BACKGROUND

Prospective studies in various cardiovascular populations show that Type D personality predicted impaired health-related quality of life (HRQoL) and disease-specific health status. We examined the effect of negative affectivity (NA), social inhibition (SI) and their combined effect (Type D personality) on HRQoL and disease-specific health status among colorectal cancer (CRC) patients.

METHODS

CRC patients diagnosed between 2000 and 2009, as registered in the Dutch population-based Eindhoven Cancer Registry, received questionnaires on Type D personality (DS14), HRQoL (EORTC QLQ-C30) and disease-specific health status (EORTC QLQ-CR38) in 2010, 2011 and 2012.

RESULTS

Response rates were 73% (n = 2625), 83% (n = 1643) and 82% (n = 1458), respectively. Analyses were done on those completing at least two questionnaires (n = 1735). Individuals with Type D (NA+/SI+; 19%) and high NA (NA+/SI-; 11%) reported a significantly worse HRQoL and disease-specific health status compared to NA-/SI+ and NA-/SI-. Differences were stable over time. Linear mixed effects models showed that Type Ds had a lower quality of life, cognitive and emotional functioning, more insomnia, diarrhea, gastrointestinal, defecation and stoma-related problems and poor body image and future perspective compared to the reference group (NA-/SI-), even after controlling for sociodemographic and clinical variables. High NA individuals (NA+/SI-) reported similar poor health outcomes as Type Ds. However, they also reported lower social functioning and more fatigue, pain, micturition- and financial problems, while Type Ds reported more constipation, sexual problems and less sexual enjoyment.

CONCLUSIONS

Type D personality and high NA both have a significant negative stable impact on HRQoL and disease-specific health status among CRC patients.

Comparison between subjective and objective methods to assess functional capacity during clinical treatment in patients with intermittent claudication

Objective

To analyze if there is any relation between functional capacity assessed by subjective and objective methods regarding the current state and after clinical treatment in patients with intermittent claudication.

Methods

A total of 500 patients with intermittent claudication were enrolled. All patients underwent clinical examination and a functional evaluation by subjective (clinical visit) and objective method (treadmill test). Additionally, 50 patients were selected to evaluate the effect of clinical treatment by subjective and objective methods in relation to functional capacity.

Results

Out of 500 patients, only 60 (12.0%) had similar results in both methods. The remaining, that is 440 patients (88.0%) had subject values in disagreement with stress test findings. Regarding the clinical effect of the treatment on the functional outcomes, results were similar in both methods (χ²=1.7; p=0.427).

Conclusion

Although the subjective method overestimates the functional capacity when compared to the objective method, no significant differences were observed between both methods when analyzing the effect of clinical treatment. Thus, the subjective method provides similar information as compared with objective method, in monitoring the clinical treatment of patients with intermittent claudication.

Distressed personality without a partner enhances the risk of depression in patients with coronary heart disease

INTRODUCTION

Cultural differences in the combined effects of Type D personality and other mediating factors in the Asian population have not been reported. We examined the influence of the Type D personality in relation to the presence of a partner by measuring symptoms of anxiety and depression, quality of life, self-perception of health status in coronary heart disease (CHD) patients and normal controls.

METHODS

Normal controls (n = 541) and patients with CHD (n = 110) were included. All participants completed self-report measures on Type D personality, questionnaires on socio-demographic factors, the Spielberger State and Trait Anxiety Inventory-State (STAI-S), and the Center for Epidemiologic Studies Depression Scale (CES-D). By stratifying participant group, personality type, and partner status, eight groups were constructed.

RESULTS

The subjects with Type D personality showed higher mean scores on the STAI-S and CES-D as well as perception of their health. In cases of depression, CHD patients with Type D personality and without partner showed about a 50-fold increase in odds ratio when compared with non-Type D normal controls with partners. Odds ratio for depression changed from 31.44 to 48.72 in CHD patients with Type D personality based on the existence of a partner.

DISCUSSION

Having a partner significantly predicted the risk of depression. It is important to identify social support systems in CHD patients with Type D personality.

The impact of type D personality and high-sensitivity C-reactive protein on health-related quality of life in patients with atrial fibrillation

BACKGROUND

Anxiety or depressive symptoms are known to be predictors of impaired health-related quality of life (HRQoL). However, little research has focused on the impact of type D personality as chronic psychological distress on HRQoL in atrial fibrillation (AF) patients. Increased high-sensitivity C-reactive protein (hsCRP) is likely to be associated with anxiety or depressive symptoms, whereas the relation of hsCRP to Type D personality was unexplored, and the impact of hsCRP on HRQoL was undetermined in AF patients.

AIM

To determine whether type D personality and hsCRP are independently associated with impaired HRQoL.

METHODS

A cross-sectional study design was used among a total of 114 patients with chronic AF. Patients underwent measurements of serum levels of hsCRP. Type D personality, anxiety and depressive symptoms, and HRQoL were assessed by the type D scale, the hospital anxiety and depression scale, and the short-form medical outcomes survey, respectively. Hierarchical linear regression was used to determine the impact of Type D personality and hsCRP on HRQoL.

RESULTS

Thirty-two percent of patients had Type D personality. Patients with type D personality had higher hsCRP than those with non-type D personality (1.4 ± 1.9 vs. 0.6 ± 2.2, p = 0.046). In hierarchical linear regression, type D personality (β = - 0.28; p = 0.005) and hsCRP (β = -0.21; p = 0.034) were independently associated with HRQoL controlling for clinical risk factors, anxiety, and depression symptoms.

CONCLUSIONS

Type D personality and hsCRP are independent predictors of impaired HRQoL. Clinicians need to pay attention to patients with Type D personality and monitor serum levels of hsCRP to prevent impaired HRQoL in AF patient.

Quality of life in perspective to treatment of postoperative edema after peripheral bypass surgery

BACKGROUND

To examine the effects of peripheral bypass surgery on patients' quality of life (QoL) as well as to compare two treatment modalities to reduce postoperative edema with regard to patients' QoL.

METHODS

This was a randomized controlled trial set in the department of vascular surgery in a nonacademic teaching hospital. Ninety-three patients (mean age, 70 years; 33% Rutherford 5-6), enrolled between August 2006 and September 2009, who underwent peripheral bypass surgery (autologous 57, polytetrafluoroethylene 36). Patients were assigned to intermittent pneumatic compression (n = 46) or to compression stockings (n = 47). The main outcome measure was QoL, measured with the World Health Organization Quality of Life assessment instrument (short form: WHOQOL-BREF).

RESULTS

QoL improved on the domain of Physical Health by 7.18 points (P < 0.001 [range, 0-100]) after 2 weeks and by 10.03 points (P < 0.001) after 3 months. Patients who received a polytetrafluoroethylene bypass scored 0.45 points (P = 0.0008 [range, 1-5]) lower at baseline on Global QoL than patients who received an autologous bypass. Type of bypass or edema treatment method did not affect the improvements. Edema did not correlate with QoL.

CONCLUSION

Improvement in QoL on the domain Physical Health following femoropopliteal bypass surgery was found as soon as 2 weeks after surgery. Improvement in QoL domains was not influenced by the type of bypass reconstruction. No specific effects of edema on QoL were detected.

Type D personality and health status in cardiovascular disease populations: a meta-analysis of prospective studies

BACKGROUND

Knowledge of the factors associated with individual differences in patient-reported outcomes is essential to identify high-risk patients and improve secondary prevention.

DESIGN

In this meta-analysis, we examined the association between Type D personality and the individual differences in patient-reported physical and mental health status among cardiovascular patients.

METHODS

A computerized search of the literature through PUBMED and PsychINFO (from 1995 to May 2011) was performed and prospective studies were selected that analysed the association between Type D personality and health status in cardiovascular patients. Two separate meta-analyses were performed for the association of Type D personality with physical and mental health status, respectively.

RESULTS

Of all identified studies, ten studies met the selection criteria. The meta-analyses showed that Type D was associated with a two-fold increased odds for impaired physical health status (3035 patients, OR 1.94, 95% CI 1.49-2.52) and a 2.5-fold increased odds for impaired mental health status (2213 patients, OR 2.55, 95% CI 1.57-4.16). There was no significant heterogeneity between the studies on physical health status (Q = 12.78; p = 0.17; I(2 )= 29.59), but there was between those on mental health status (Q = 21.91; p = 0.003; I(2 )= 68.04). Subgroup analyses showed that the association between Type D and mental health status decreased yet remained significant when adjusting for baseline health status.

CONCLUSION

Type D personality was shown to be an independent correlate of impaired patient-reported physical and mental health status in various cardiovascular patient groups. Clinicians should be aware of the association between chronic psychological distress and poor patient-reported outcomes.

Personality traits and medical outcome of cardiac illness

OBJECTIVE

Our goal was to examine the empirical literature on the effect of personality traits on the medical outcome of cardiac illness.

METHOD

Pub Med and Psychological Abstracts were searched for the years 1990 to September 2009 using the terms personality, personality traits, personality disorder, health, recovery from illness, cardiac illness and surgical recovery. Articles were then selected that were prospective, had a peer review published measure of personality, a standardized measure of outcome of physical illness and at least one year follow up.

RESULTS

Seven articles were identified that met our criteria. All seven had a significant finding that personality traits predicted medical outcomes. Of these seven articles six had similar enough measures of personality to be included in a meta analysis. (All used Type D personality.) Meta analysis found an odds ratio of 3.76 for Type D personality traits predicting poorer medical outcome. This indicated that patients with Type D personality had a 276% increase in the odds of a poor medical outcome compared to patients without Type D personality.

CONCLUSIONS

These findings indicate that personality traits are a strong predictor of medical outcome of cardiac disease.

Quality of life three years after major lower extremity amputation due to peripheral arterial disease

BACKGROUND AND AIMS

The purpose of this study was to assess the quality of life (QoL) of peripheral arterial disease (PAD) amputees.

PATIENTS AND METHODS

Fifty-nine PAD patients (mean age 75.2, SD 10.7, range 39-96, 47% men) who had undergone their first major lower leg amputation (LEA) on average 2.7 years earlier (in 1998-2002) were interviewed, and 118 age- and gender-matched controls completed a postal questionnaire. Outcomes were assessed with 15D Health-Related QoL instrument, Rand-36 Physical Functioning- and General Health subscales, Geriatric Depression Scale, 6-item Brief Social Support Questionnaire, and Self-reported Life Satisfaction score.

RESULTS

The amputees had more diseases than their controls. HRQoL was lower among amputees than among controls. Half the amputees lived in institutional care, 25% had a Mini-Mental Examination score <18, and 22% had unilateral belowknee amputations only. The amputees had a similar self-assessed sense of their general state of health, life satisfaction and perceived social support as controls. Amputees who were institutionalized and those who did not use prostheses had more symptoms of depression than those who lived at home or used prostheses.

CONCLUSION

Home-dwelling amputees had a relatively good QoL, whereas institutionalization was associated with depressive symptoms. In rehabilitation programs, not only physical disability assessment but also QoL should be considered.

Optimizing supervised exercise therapy for patients with intermittent claudication

BACKGROUND

The first-line intervention for intermittent claudication is usually supervised exercise therapy (SET). The literature describes a range of exercise programs varying in setting, duration, and content. The purpose of the present study was to examine the exercise protocols offered and to identify the impact of the intensity of the SET programs (in terms of frequency, duration, and type of exercise) on improvements in walking distance (response) in the first 3 months. The present study is part of the Exercise Therapy in Peripheral Arterial Disease (EXITPAD) study, a multicenter randomized clinical trial comparing the effects of SET provided by regional physiotherapists, with or without daily feedback, on the level of activities with the effects of walking advice.

METHODS

The analysis included patients randomized to receive SET with or without feedback. The physical therapists administering the SET were asked to fill out therapy evaluation sheets stating frequency, duration, and type of exercises. The relationship between training volume and the impact on walking distance was explored by dividing training volume data into tertiles and relating them to the median change in maximum walking distance at 3 and 12 months.

RESULTS

Data of 169 patients were included in the analysis. A SET program consisting of at least two training sessions per week each lasting over 30 minutes, during the first 3 months of a 1-year program tailored to individual patients' needs led to better results in terms of walking distance after 3 and 12 months than the other variants. The results of our analysis dividing training volume into tertiles suggest that there is a relationship between training volume and improvement in walking distance and that at least 590 minutes of training should be offered in the first 3 months. No differences were found between program involving only walking and a combination of exercises, nor between individual and group training.

CONCLUSION

A SET programs consisting of at least two training sessions a week, each lasting over 30 minutes, should be offered during the first 3 months of the SET program to optimize improvement in terms of maximum walking distance.

Is type-D a stable construct? An examination of type-D personality in patients before and after cardiac surgery

OBJECTIVE

Type-D personality-negative affectivity and social inhibition-are related to poor prognosis in cardiovascular diseases. At present, little is known about type-D personality and its stability before and after cardiac surgery.

METHODS

One hundred twenty-six patients recommended for coronary bypass and/or valve surgery were examined at pre-surgery and 6 months post-surgery to investigate the stability of type-D (14-item Type-D Scale) and its relationship to anxiety, depression (Hospital Anxiety and Depression Scale) and quality of life (Short Form 12).

RESULTS

Preoperatively, 26% were assessed to have type-D, while only 11% fulfilled type-D criteria both pre- and post-surgery. Patients were assessed and identified as belonging to one of the four type-D groups: Stable type-D (11%), non-type-D (61%), type-D pre (15%), and type-D post (13%). In comparison to the stable non-type D group, the stable type-D reported more symptoms of anxiety, depression, lower physical quality of life post-surgery, and lower mental quality of life both pre- and post-surgery. When compared to the population at large, stable type-D had more symptoms of depression pre-surgery, and more anxiety as well as lower physical and mental quality of life pre- and post-surgery.

CONCLUSION

Type-D diagnosis changed in nearly 60% of the cases post-surgery. Only those patients with stable type-D exhibited a relationship to emotional distress, such as anxiety and depression and reduced quality of life. Additional research on the critical cut-off scores and stability of type-D as it relates to critical life events would likely enhance our ability to more effectively diagnose and treat patients who are at high risk for insufficient coping.

Pain management in peripheral arterial obstructive disease: oral slow-release oxycodone versus epidural l-bupivacaine

OBJECTIVES

To compare the effectiveness of oral slow-release oxycodone (group OX, n=18) with that of epidural l-bupivacaine (group LRA, n=13) for the control of moderate/severe pain of advanced-stage peripheral arterial obstructive disease (PAOD) patients.

DESIGN

Observational and retrospective analysis of advanced stage and hospitalised PAOD patients treated for pain management for at least 7 days prior to surgery or discharged from the hospital without surgery.

METHODS

The outcome measures were pain intensity using the visual analogue scale under static, (VASs) and dynamic (VASd) conditions; vital signs, treatment side effects and patient satisfaction.

RESULTS

In both groups, pain control was satisfactory and VAS scores median were VASs<3 and VASd<4; under dynamic conditions, pain control was better in the LRA group (p<0.01). Against few and transient side effects, most patients (n=30) found both pain treatments good or excellent. Results should be confirmed by studies with larger samples.

CONCLUSIONS

In the perioperative setting, the epidural infusion of local anaesthetics, such as l-bupivacaine, is an effective technique for pain control in PAOD patients; for patients with contraindication for this technique or for non-surgical or outpatients, slow-release oxycodone is suggested as a possible alternative for the control of severe pain in these patients.

Clustering of negative affectivity and social inhibition in the community: prevalence of type D personality as a cardiovascular risk marker

OBJECTIVE

To explore the prevalence of Type D personality-the combination of negative affectivity and social inhibition-in the general population and its relationship to other cardiovascular risk factors, including psychopathological symptoms. Type D personality has been identified as a prognostic risk factor for various cardiovascular disease conditions.

METHODS

In a representative sample of 2698 individuals (aged 35-74 years), psychological, lifestyle, and somatic risk factors were investigated with laboratory testing, self-report measures, and a clinical interview. Type D was assessed with the German Type D Scale-14.

RESULTS

The prevalence of Type D was 23.4% (95% confidence interval [CI], 21.2-25.6) in men and 26.9% (95% CI, 23.7-30.1) in women and, thus, in the range of classical risk factors (e.g., hypercholesterolemia). In age-adjusted analysis, Type D was associated with psychopathological symptoms, including depression and somatic symptom burden. With the exception of physical inactivity in both sexes, hypertension in women and hypercholesterolemia in men, Type D was not associated with classical cardiovascular risk factors. Multivariate analysis revealed depression, exhaustion, anxiety, and low self-rated health as associated with Type D in both sexes (odds ratios, 1.97-3.21 in men, 1.52-2.44 in women).

CONCLUSIONS

A Type D personality disposition can be found in about a quarter of the general population, which is comparable to the prevalence of classical cardiovascular risk factors. In both sexes, an independent association to Type D appeared mainly in psychopathological symptoms. Type D constitutes a relevant and independent risk marker in the community and should receive attention in clinical practice.

Impact of peripheral arterial disease on health status: a comparison with chronic heart failure

OBJECTIVE

To further document the experienced burden in patients with peripheral arterial disease (PAD), we compared the health status of patients with PAD and chronic heart failure (CHF). As a secondary aim, we studied clinical and socio-demographic correlates of health status in both conditions.

METHODS

We conducted a cross-sectional observational study in four outpatient clinics in the Southern part of The Netherlands, with subjects consisting of ambulatory (346 PAD and 188 CHF) patients. All patients completed the Short-Form 12 to assess their physical and mental health status. Information about socio-demographic, clinical risk factors, and disease severity indices was obtained from patients' medical records. Propensity methodology was applied to enhance comparability between both medical conditions.

RESULTS

Type of medical condition explained differences in health status (F = 33.1, P < .0001, Effect Size = 0.27). Impaired physical health status was more often reported in PAD patients (48.4%) compared with CHF patients (17.4%, Odds Ratio [OR] = 4.4, 95% Confidence Interval [CI] 2.3-8.8, P < .0001); impaired mental health status was more noted in CHF patients (43.5% vs. 22.0%, OR = 1.7, 95% CI 1.2-2.6, P = .002). In PAD, younger age (P = .002), low education (P = .02), cardiac history (P = .02), diabetes mellitus (P = .03), and a lower ankle brachial index (P = .003) were associated with worse physical health status; younger age (P = .01) and living without partner (P = .01) were associated with lower mental health status scores. In CHF, patients with comorbid diabetes mellitus (P < .001) and females (P = .001) reported worse physical health, whereas no clinical or socio-demographics were associated with mental health status.

CONCLUSIONS

By contrasting PAD patients' health status with another chronic disabling condition, the impact of PAD on patients' physical health status became evident; whereas mental health status was more affected in CHF, patients with PAD reported a greater physical burden as compared with CHF patients. PAD patients who were younger, lower-educated, without a partner or had a cardiac history especially reported a higher disease burden. Clinicians need to be aware of these differences in order to develop tailor-made disease management programs for different groups of cardiovascular patients.
