The role of psychopathology in perceiving, reporting and treating intermittent claudication: a systematic review

Addressing Psychosocial Care Needs in Women with Peripheral Artery Disease

PURPOSE OF REVIEW

Peripheral artery disease (PAD) is a growing global epidemic. Women with PAD are at elevated risk of experiencing psychosocial stressors that influence the diagnosis, management, and course of their illness due to unique sex- and gender-based factors.

RECENT FINDINGS

We review existing evidence for increased psychosocial risk in women with PAD with a focus on mood disorders, chronic stress, pain experiences, substance use disorders, health behaviors and illness perceptions, and healthcare access. We discuss how these factors exacerbate PAD symptomatology and lead to adverse outcomes. Existing gaps in women's vascular care are reviewed and potential solutions to bridge these gaps through psychosocial care integration are proposed. Current care paradigms for women's vascular care do not adequately screen for and address psychosocial comorbidities. Clinician education, integration of evidence-based psychological care strategies, implementation of workflows for the management of individuals with PAD and mental health comorbidities, reform to reimbursement structures, and further advocacy are needed in this space. This review provides a construct for integrated behavioral health care for women with PAD and advocates for further integration of care.

Association Between Mental Health Burden, Clinical Presentation, and Outcomes in Individuals With Symptomatic Peripheral Artery Disease: A Scientific Statement From the American Heart Association

Along with the rising burden of peripheral artery disease (PAD), mental health concerns are increasingly being recognized as a comorbidity to address in the chronic disease management of symptomatic PAD. Apart from a high prevalence of comorbid mental health conditions, the role of pain and changing health behaviors and the broader impacts of illness and adaptation to living with PAD require specialized behavioral health expertise. This scientific statement builds a case that this expertise should be integrated within the multidisciplinary PAD team. Furthermore, areas such as cognitive dysfunction and palliative care are highlighted as needing psychological interventions. Although much of the evidence of the efficacy of psychological and psychotropic interventions has been extrapolated from other cardiovascular populations, evidence for the role of psychological interventions for behavior change, for example, uptake of exercise regimens, is increasingly being accrued within PAD. Areas for behavioral health needs and interactions with PAD treatment are discussed, including the use of opioids, depression management, anxiety and stress reduction interventions, the use of benzodiazepines and antidepressants, smoking cessation, rehabilitation trajectories after amputation, and the role of cognitive decline for PAD treatment and outcomes. A case summary highlights the stigma around mental health and vascular disease and the fragmentation of care. This scientific statement provides remarks for building a road map for integrated behavioral PAD care and potential solutions to overcome these barriers. Instrumental to reaching these changes are interprofessional advocacy efforts and initiatives that help break down the stigma around mental health and promote evidence-based collaborative, nonhierarchical, and multidisciplinary PAD care.

Impact of physical activity on self-reported health parameters in peripheral artery disease in two periods of the COVID-19 pandemic

BACKGROUND

Prolonged social isolation intended to mitigate the spread of Coronavirus 2019 (COVID-19), may potentially affect the physical activity level and health of patients with peripheral artery disease (PAD).

OBJECTIVES

To analyze the impact of physical activity practice on longitudinal changes in self-reported health parameters during the COVID-19 pandemic in patients with PAD.

DESIGN

Longitudinal study.

SETTING

The database of studies developed by our group involving patients with PAD from public hospitals in São Paulo, Brazil.

METHODS

In this longitudinal study, 99 patients with PAD were evaluated in two periods during the COVID-19 pandemic (i.e., May to August 2020 and May to August 2021). Patients were interviewed by telephone, and information was obtained regarding physical activity practice and self-reported health (i.e., current global, physical, and mental health). Patients were divided into two groups: the physically inactive group (patients who were or became physically inactive, n=76, 51.3% male, 67±10 years old, 8±7 years of disease duration) and the physically active group (patients who started or continued practicing physical activity, n=23, 65.2% male, 71±8years old, 7±6 years of disease).

RESULTS

The physically inactive group more frequently self-reported their current health as poor (6.6 vs. 17.1%, P=0.045) and were more frequently hospitalized for reasons other than COVID-19 (6.6 vs. 27.6%, P=0.001) between the two periods evaluated during the COVID-19 pandemic. The physically active group self-reported lower declines in walking capacity (13.0 vs. 43.5%, P=0.022) between the two periods evaluated. We did not observe any differences in other parameters in either group between the two periods evaluated (p>0.05).

CONCLUSIONS

The practice of physical activity during the COVID-19 pandemic can help maintain or mitigate the negative impacts on self-reported global and physical health parameters in patients with PAD.

Vascular Inflammatory Markers as Predictors of Peripheral Arterial Disease Patients' Quality-of-Life Changes after Endovascular Treatment

The association between chronic inflammation and depression, anxiety, anhedonia, and quality of life (QoL) has been recently emphasized. However, the pathophysiology of this relationship remains unsolved. This study aims to assess the dependence between vascular inflammation represented by eicosanoid concentration and quality of life in patients with peripheral arterial disease (PAD). A total of 175 patients undergoing endovascular treatment due to lower limbs ischemia were covered with eight years of observation after the endovascular procedure, including ankle-brachial index (ABI), color Doppler ultrasound examination, urinary leukotriene E4 (LTE4), thromboxane B2 (TXB2) and 5-Hydroxyeicosatetraenoic acid (5-HETE) measurement and quality-of-life assessment with VascuQol-6. The baseline concentrations of LTE4 and TXB2 reversely correlated with preoperative VascuQol-6 and were predictive of the postoperative values of VascuQol-6 at each follow-up. At every follow-up timepoint, the results of VascuQol-6 reflected the LTE4 and TXB2 concentrations. Higher concentrations of LTE4 and TXB2 were correlated with lower life quality during the next follow-up meeting. Changes in VascuQol-6 at eight years vs. preoperative values were reversely related to the preoperative concentrations of LTE4 and TXB2. This is the first study to confirm that changes in life quality in PAD patients undergoing endovascular treatment are highly dependent on eicosanoid-based vascular inflammation.

Impact of the COVID-19 pandemic on health lifestyle in patients with peripheral artery disease: A cross-sectional study

Background

Social isolation has been one of the main strategies to prevent the spread of Coronavirus 2019 (COVID-19). However, the impact of social isolation on the lifestyle of patients with peripheral artery disease (PAD) and claudication symptoms remains unclear.

Objectives

To analyze the perceptions of patients with PAD of the impact of social isolation provoked by COVID-19 pandemic on health lifestyle.

Design

Cross-sectional.

Setting

The database of studies developed by our group involving patients with PAD from public hospitals in São Paulo.

Methods

In this cross-sectional survey study, 136 patients with PAD (61% men, 68 ± 9 years old, 0.55 ± 0.17 ankle-brachial index, 82.4% with a PAD diagnosis ≥5 years old) were included. Health lifestyle factors were assessed through a telephone interview using a questionnaire containing questions related to: (a) COVID-19 personal care; (b) mental health; (c) health risk habits; (d) eating behavior; (e) lifestyle; (f) physical activity; (g) overall health; and (h) peripheral artery disease health care.

Results

The majority of patients self-reported spending more time watching TV and sitting during the COVID-19 pandemic and only 28.7% were practicing physical exercise. Anxiety and unhappiness were the most prevalent feelings self-reported among patients and 43.4% reported a decline in walking capacity.

Conclusion

Most patients with PAD self-reported increased sedentary behavior, lower physical activity level, and worse physical and mental health during the COVID-19 pandemic. Thus, it is necessary to adopt strategies to improve the quality of life of these patients during this period.

Supervised Exercise Therapy is Effective for Patients With Intermittent Claudication Regardless of Psychological Constructs

OBJECTIVE

According to current guidelines, supervised exercise therapy (SET) is the treatment of choice for intermittent claudication (IC). Little is known about the potential consequences of psychological factors on the effectiveness of treatment. The aim of this study was to determine possible associations between a set of psychological constructs and treatment outcomes, and to investigate whether self efficacy increased after SET.

METHODS

This was a substudy of the ELECT Registry, a multicentre Dutch prospective cohort study in patients with IC receiving primary SET. A complete set of validated questionnaires scoring extraversion, neuroticism, conscientiousness, anxiety, depression, self control, optimism, and self efficacy was obtained in 237 patients (median age 69 years, 40% female). Anxiety and depression were dichotomised using established cutoff scores, whereas other scores were analysed as continuous measures. Multiple linear regression analyses determined possible associations between these independent variables and maximum and functional walking distances (MWD and FWD, respectively), Six Minute Walk Test (6MWT), and VascuQol-6 (dependent variables). Self efficacy during 12 months of SET was analysed using a linear mixed model.

RESULTS

Neuroticism and anxiety were associated with lower overall VascuQol-6 scores (estimate -1.35 points [standard error (SE) 0.57; p = .018] and -1.98 points [SE 0.87, p = .023], respectively). Optimism and self efficacy demonstrated higher overall 6MWT (5.92 m [SE 2.34; p = .012] and 1.35 m [SE 0.42; p = .001], respectively). Self control was associated with lower overall log MWD (-0.02 [SE 0.01; p = .038] and log FWD (-0.02 [SE 0.01; p = .080), whereas self efficacy had a higher overall log MWD (0.01 [SE 0.003; p = .009]) and log FWD (0.01 [SE 0.003; p = .011]). Depressive patients with IC demonstrated a greater improvement in 6MWT during follow up (17.56 m [SE 8.67; p = .044]), but this small effect was not confirmed in sensitivity analysis. Self efficacy did not increase during follow up (0.12% [SE 0.49; p = .080]).

CONCLUSIONS

The beneficial effects of SET occur regardless of the psychological constructs, supporting current guidelines recommending a SET first strategy in each patient with IC.

Depression among predictors of intermittent claudication: A cross-sectional study

PURPOSE

The aim of the present cross-sectional study was to investigate the relationship between depression and intermittent claudication (IC), independently of traditional risk factors.

MAIN METHODS

The sample consisted of 300 individuals (M age = 65.3 ± 8.7 years, 61.0% female) recruited from the offices of 33 general practitioners. Participants' medical history and the presence of major cardiovascular risk factors were recorded. Participants completed the Edinburgh Claudication Questionnaire. The role of depression (assessed by a shortened version of the Beck Depression Inventory) in predicting IC was examined using a binary logistic regression analysis - controlled for sex, age, hypertonia, diabetes, smoking, hypercholesterinemia, hazardous drinking, and body mass index (BMI).

RESULTS

The descriptive data indicated that the prevalence of depression was 57.9% in the IC subgroup and 16.1% in those free of IC. The bivariate analyses indicated that hypercholesterinemia, smoking, hazardous drinking, BMI, and depression were significantly associated with IC. Male sex and age showed a trend toward being a significant correlate of IC. Results of the multivariate analyses indicated that depressive symptomatology was significant in predicting IC (OR: 1.08 (1.05-1.11)), even after controlling for lifestyle and traditional risk factors such as smoking, hazardous drinking, and BMI. Among traditional risk factors, smoking (OR: 2.44 (1.26-4.74)), hazardous drinking (OR: 1.19 (1.02-1.40)), and hypercholesterinemia (OR: 2.17 (1.26-3.75)) showed a significant, positive relationship with IC.

CONCLUSIONS

These results underscore the importance of a multidisciplinary approach that focuses on supporting health-related behavioral changes and managing mental health symptoms when providing care for patients with IC.

A Comparison of Health Status and Quality of Life in Patients with Intermittent Claudication

BACKGROUND

Patient reported outcome measures (PROMs) such as health status (HS) and quality of life (QOL) are frequently used interchangeably while they represent different outcomes. Whether a discrepancy exists in patients with intermittent claudication (IC) in changes over time between HS and QOL is unclear. This study aimed to investigate the strength and the direction of the association between HS and QOL over time in patients with IC that underwent supervised exercise therapy (SET).

MATERIAL AND METHODS

Patients were part of the ELECT multi-center prospective cohort study. One goal of this study was to obtain data on HS and QOL at different time intervals of patients with IC that underwent SET. HS (VascuQOL-6) and QOL (WHOQOL-BREF) were completed at baseline, 3 months, and 6 months follow up. Pearson's correlation coefficients and the associated common variances (R²) were calculated to measure the strength and the direction of the association between HS and QOL in changes between baseline and follow-up moments.

RESULTS

In total, 177 patients were included in data analyses. Only changes in physical QOL and overall QOL had a small correlation with changes over time in HS, at both 3- and 6 months follow up (respectively R²=.14; P < 0.001 and R² = 0.12; P < 0.001 for physical QOL and R² = 0.18; P < 0.001 and R² = 0.13; P < 0.001 for overall QOL).

CONCLUSIONS

This study showed that HS and QOL provide different outcomes in patients with IC that underwent SET. Future studies should be aware of these differences before PROMs are being incorporated as an outcome measure in clinical studies.

Personality Profile and Low Back Pain: Are Clinicians Missing an Important Factor That Influences Pain Perception and Treatment Options?

Personality type can influence pain perception and prognosis. Therefore, it is important for clinicians to consider personality factors that may influence outcomes and understand personality inventories to garner a better understanding of how an individual may perceive pain. This paper explores different elements that contribute to low back pain (LBP) and evaluates a personality inventory reported in the medical literature. Understanding how to evaluate personality type as well as how to approach clinical interactions based on personality may help to provide context for the unique needs of individual patients when developing a plan of care to treat LBP.

Depressive symptomatology and personality traits in patients with symptomatic and asymptomatic peripheral arterial disease

Background

The aim of this study was to examine the relationship of depressive symptomatology and personality traits with peripheral arterial disease (PAD).

Methods

The sample of this cross-sectional study comprised of 300 individuals (M_age = 65.3 ± 8.7 years, 61.0% female) recruited from the offices of 33 general practitioners. Based on at-rest ankle-brachial index (ABI) values and claudication symptoms, four subsamples were formed: clear PAD-positive, clear PAD-negative, ABI-negative but symptomatic, and a non-compressible-artery group. The concurrent role of depression (assessed by a shortened version of the Beck Depression Inventory) and personality traits (measured by the Big Five Inventory) in predicting PAD status was examined using multinomial logistic regression – controlled for sex, age, hypertonia, diabetes, smoking, hazardous drinking, and body mass index.

Results

Depressive symptomatology was significant in predicting peripheral arterial disease status even after controlling for both traditional risk factors and personality traits. Among the Big Five personality traits, neuroticism showed a significant, positive relationship with PAD – independently of depression.

Conclusions

Patients with PAD – even those with asymptomatic forms of the disease – are at higher risk for suffering from depression compared to individuals without PAD, independently of neuroticism, other Big Five personality dimensions or traditional risk factors for cardiovascular diseases.
