Spontaneous coronary artery dissection in patients with prior psychophysical stress: a systematic review of case reports and case series.

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is an underdiagnosed cause of acute coronary syndrome, particularly in younger women. Due to limited information about SCAD, case reports and case series can provide valuable insights into its features and management. This study aimed to comprehensively evaluate the features of SCAD patients who experienced psychophysical stress before the SCAD event. METHODS: We conducted an electronic search of PubMed, Scopus, and Web of Science from inception until January 7, 2023. We included case reports or series that described patients with SCAD who had experienced psychophysical stress before SCAD. Patients with pregnancy-associated SCAD were excluded from our analysis. RESULTS: In total, we included 93 case reports or series describing 105 patients with SCAD. The average patient age was 44.29 ± 13.05 years and a total of 44 (41.9%) of patients were male. Among the included SCAD patients the most prevalent comorbidities were fibromuscular dysplasia (FMD) and hypertension with the prevalence of 36.4 and 21.9%, respectively. Preceding physical stress was more frequently reported in men than in women; 38 out of 44 (86.4%) men reported physical stress, while 36 out of 61 (59.1%) females reported physical stress (p value = 0.009). On the other hand, the opposite was true for emotional stress (men: 6 (13.6%)), women: 29 (47.6%), p value < 0.001). Coronary angiography was the main diagnostic tool. The most frequently involved artery was the left anterior descending (LAD) (62.9%). In our study, recurrence of SCAD due to either the progression of a previous lesion or new SCAD in another coronary location occurred more frequently in those treated conservatively, however the observed difference was not statistically significant (p value = 0.138). CONCLUSION: While physical stress seems to precede SCAD in most cases, emotional stress is implicated in females more than males.

A state-of-the-art review of quality-of-life assessment in venous disease.

OBJECTIVE: Chronic venous disease is a common condition and has a significant impact on patients' health status. Validated patient-reported outcome measures (PROMs) used to assess health status are needed to measure health status. This state-of-the-art review summarizes the current validation evidence for disease-specific PROMs for chronic venous disease and provides a framework for their use in the clinical setting. METHODS: A literature search in OVID Embase and Medline was conducted to identify relevant English-language studies of chronic venous disease that used disease-specific PROMs between January 1, 1993, and June 30, 2022. Abstracts and titles from identified studies were screened by four investigators, and full-text articles were subsequently screened for eligibility. Data on validation of disease-specific PROMs was abstracted from each included article. Classical test theory was used as a framework to examine a priori defined validation criteria for content validity, reliability (construct validity, internal reliability, and test-retest reliability), responsiveness, and expansion of the validation evidence base (use in randomized controlled trials and comparative effectiveness research, cultural or linguistic translations, predictive validity, or establishing the minimal clinically important difference threshold, defined as smallest amount an outcome or measure is perceived as a meaningful change to patients). The PROMs were categorized into three groups based on the manifestations of disease of the population for which they were developed. The overall validity of each PROM was assessed across three stages of validation including content validity (phase 1); construct validity, reliability, and responsiveness (phase 2); and expansion of the validation evidence base (phase 3). RESULTS: Of 2338 unique studies screened, 112 studies (4.8%) met inclusion criteria. The eight disease-specific PROMs identified were categorized into three groups: (1) overall chronic venous disease (C1 to C6); (2) C1 to C4 disease; and (3) C5 to C6 disease. Assessed by group, the Chronic Venous Insufficiency Questionnaire met criteria for validation at all three phases for patients with C1 to C4 disease, and the Charing Cross Venous Ulcer Questionnaire met criteria for validation at all three phases for patients with C5 to C6 disease. There were no PROMs that met all criteria for validation for use in overall chronic venous disease (C1 to C6). CONCLUSIONS: Of the eight PROMs assessed in this review, only two met prespecified criteria at each phase for validation. The Chronic Venous Insufficiency Questionnaire and Charing Cross Venous Ulcer Questionnaire should be considered for use in patients with chronic venous disease without venous ulcers and with venous ulcers, respectively.

White matter hyperintensities and cognition across different Alzheimer's biomarker profiles.

BACKGROUND/OBJECTIVES: To examine the association between white matter hyperintensities (WMH) and cognitive domains such as memory and executive function (EF) across different clinical and biomarker categories of Alzheimer's disease (AD). DESIGN: Cross-sectional study. SETTING: Alzheimer's Disease Neuroimaging Initiative. PARTICIPANTS: A total of 216 cognitively normal (CN) participants and 407 participants with mild cognitive impairment (MCI) from the Alzheimer's Disease Neuroimaging Initiative (ADNI) at baseline. MEASUREMENTS: Based on the 2018 research framework, participants were classified using AT(N) (amyloid-ß deposition [A], pathologic tau [T], and neurodegeneration [(N)]) biomarkers into one of three categories: biomarker negative [A - T- (N)-], amyloid negative but other biomarker positive [A - T ± (N)+ or A - T + (N)±] or amyloid positive [A + T ± (N)±]. Linear regression models were then used to examine the association between WMH and memory composite scores and EF composite scores. RESULTS: Higher WMH burden was associated with worse EF in both CN and MCI subgroups while a significant association between WMH and memory was only found in the MCI subgroup. Furthermore, WMH was associated with EF in the group with A - T ± (N)+ or A - T + (N)± biomarker category, but not for A - T - (N)- (normal biomarker) and A + T ± (N) ± (AD pathology). The association between higher WMH and worse memory was independent of amyloid levels in individuals with MCI with evidence of AD pathology. CONCLUSION: Vascular disease, as indexed by WMH, independent of AD pathology affects cognitive function in both CN and MCI subgroups. Future studies using the AT(N) research framework should consider white matter lesions as a key biomarker contributing to the clinical presentation of AD.

Correlation of Patient Activation Measure Level with Patient Characteristics and Type of Vascular Disease.

BACKGROUND: Patient activation or level of engagement in one's medical care is linked to hospital readmissions and worse outcomes in a number of diseases. Patients with higher levels of activation are typically guiding their care rather than acting as passive observers of care. This study aims to determine if either patient demographics or type of vascular disease can predict patient activation. METHODS: All patients presenting over a 4-month period to an outpatient vascular clinic were asked to complete the Patient Activation Measure (PAM) survey. In total, 257 completed surveys were collected. Survey responses were scored on a Likert scale with anchors. Responses are tallied with a score of 1-100 and converted to summary levels 1-4 in accordance with the previously validated scoring system. Level 1 patients are considered disengaged and overwhelmed. Patients in level 2 are becoming aware of their health care, but still struggle. Level 3 patients are taking action, while level 4 represents patients who are maintaining healthy behaviors and pushing further. Chi-squared test and multivariable regression were then performed to determine if patient characteristics or type of disease correlated with activation levels. RESULTS: In total, 257 patients completed the survey. The mean participant age was 67 years (±15). Sixteen percent of patients lived alone, 58% were married, and in 39% mean household income was <$50,000. Overall, 21 patients (8.2%) were classified as level 1, 65 (25%) level 2, 94 (37%) level 3, and 77 (30%) level 4. The group comprised 32% peripheral artery disease (PAD), 20% carotid, 18% aortic/aneurysm, 14% venous, and 16% were various other vascular diseases. Over each disease group there was a wide range of activation, but no significant difference between the type of vascular disease and activation level. Chronic limb-threatening ischemia (CLTI) patients comprised 35% (n = 29) of the PAD group, and 66% of these patients reported an activation level of 3 (n = 10) or 4 (n = 9). There was no difference in the levels of activation reported by the CLTI patients compared to the general PAD cohort (P = 0.99). Multivariable analysis demonstrated that age, level of education, household income, and type of vascular disease correlated with PAM score, but there was no correlation between length of symptoms, race, or gender. CONCLUSIONS: Patient activation is unpredictable using patient characteristics or type of vascular disease, and CLTI patients report high activation levels. Quality databases that collect only patient demographics may not fully capture patient predictors of poor outcomes. Use of the PAM survey should be further explored in vascular patients to correlate activation level with vascular-specific outcomes.

Spontaneous Coronary Artery Dissection in Relation to Physical and Emotional Stress: A Retrospective Study in 4 Arab Gulf Countries.

Spontaneous coronary artery dissection (SCAD) has emerged as an important cause of acute coronary syndrome and sudden cardiac death. The triggers for SCAD often do not include traditional atherosclerotic risk factors. The most commonly reported triggers are extreme physical or emotional stress. The current study compared in-hospital and follow-up events in patients with SCAD with and without reported stress. Data from 83 patients with a confirmed diagnosis of SCAD were collected retrospectively from 30 centers in 4 Arab Gulf countries (KSA, UAE, Kuwait, and Bahrain) from January 2011 to December 2017. In-hospital myocardial infarction (MI), percutaneous coronary intervention (PCI), ventricular tachycardia/ventricular fibrillation, cardiogenic shock, death, ICD placement, dissection extension) and follow-up (MI, de novo SCAD, death, spontaneous superior mesenteric artery dissection) events were compared between those with and without reported stress. Emotional and physical stress was defined as new or unusually intense stress, within 1 week of their initial hospitalization. The median age of patients in the study was 44 (37-55) years. Foty-two (51%) were women. Stress (emotional, physical, and combined) was reported in 49 (59%) of all patients. Sixty-two percent of women with SCAD reported stress, and 51 % of men with SCAD reported stress. Men more commonly reported physical and combined stress. Women more commonly reported emotional stress (P < 0.001). The presence or absence of reported stress did not impact on overall adverse cardiovascular events (P = 0.8). In-hospital and follow-up events were comparable in patients with SCAD in the presence or absence of reported stress as a trigger.

Associations between Antiretrovirals and Cognitive Function in Women with HIV.

Cognitive complications persist in antiretroviral therapy(ART)-treated people with HIV. However, the pattern and severity of domain-specific cognitive performance is variable and may be exacerbated by ART-mediated neurotoxicity. 929 women with HIV(WWH) from the Women's Interagency HIV Study who were classified into subgroups based on sociodemographic and longitudinal behavioral and clinical data using semi-parametric latent class trajectory modelling. Five subgroups were comprised of: 1) well-controlled HIV with vascular comorbidities(n = 116); 2) profound HIV legacy effects(CD4 nadir <250 cells/µL; n = 275); 3) primarily <45 year olds with hepatitis C(n = 165); 4) primarily 35-55 year olds(n = 244), and 5) poorly-controlled HIV/substance use(n = 129). Within each subgroup, we fitted a constrained continuation ratio model via penalized maximum likelihood to examine adjusted associations between recent ART agents and cognition. Most drugs were not associated with cognition. However, among the few drugs, non-nucleoside reverse transcriptase inhibitor (NNRTIs) and protease inhibitors(PIs) were most commonly associated with cognition, followed by nucleoside reverse transcriptase inhibitors(NRTIs) and integrase inhibitors(IIs). Directionality of ART-cognition associations varied by subgroup. Better psychomotor speed and fluency were associated with ART for women with well-controlled HIV with vascular comorbidities. This pattern contrasts women with profound HIV legacy effects for whom poorer executive function and fluency were associated with ART. Motor function was associated with ART for younger WWH and primarily 35-55 year olds. Memory was associated with ART only for women with poorly-controlled HIV/substance abuse. Findings demonstrate interindividual variability in ART-cognition associations among WWH and highlight the importance of considering sociodemographic, clinical, and behavioral factors as an underlying contributors to cognition. Are antiretroviral agents a risk factor for cognitive complications in women with HIV? We examind associations between ART-agents and cognitive function among similar subgroups of women with HIV from the Women's Interagency HIV study. The patterns of associations depended on sociodemographic, clinical, and behavioral characteristics of women.

Perspectives on blood pressure by patients on haemo- and peritoneal dialysis.

AIM: The management of blood pressure in patients requiring dialysis remains challenging and controversial. This study aimed to describe the perspectives of patients treated with peritoneal or haemodialysis regarding blood pressure, to inform patient-centred management. METHODS: We conducted a secondary thematic analysis of qualitative data from multiple data sets derived from the Standardised Outcomes in Nephrology (SONG) initiative. We extracted and analysed the responses of adult patients (aged 18 years or over) on haemodialysis and peritoneal dialysis, and their caregivers. Qualitative data were extracted from 26 focus groups, two international Delphi surveys and two consensus workshops completed as part of the SONG-Haemodialysis and SONG-Peritoneal dialysis projects. RESULTS: Collectively, the studies involved 644 patients and caregivers from 86 countries. We identified four themes: helpless and incapacitated (including the subthemes of disabling and debilitating symptoms, limiting ability to work, fear of "crashes" - a sudden drop in blood pressure - forced to depend on others); dismissed and ignored (disregarded as a problem, lacking information, education and reassurance); escalating medication burden; and taking control for improved self-management (determining thresholds in fluid management, establishing a routine for proactive monitoring). CONCLUSION: Blood pressure symptoms are debilitating for patients on dialysis and exacerbated by a perceived lack of information about how to understand and manage these symptoms. More patient-centred management of blood pressure, particularly symptom-causing blood pressure, in patients on dialysis is likely to substantially improve patient satisfaction and outcomes.

Transcranial direct current stimulation: A novel approach in the treatment of vascular depression.

BACKGROUND: Despite the impact of depression in terms of personal suffering and socioeconomic burden, most currently available treatment options are often ineffective. A particularly difficult-to-treat depressive disorder characteristic of the elderly is vascular depression, a late-life depressive syndrome related to a variety of potential vascular mechanisms. Transcranial Direct Current Stimulation (tDCS), a non-invasive and effective somatic approach to depression, also showed positive effects on cognitive deficits. AIM: We performed a double-blind randomized study to investigate the efficacy of tDCS as augmentation strategy to sertraline in the treatment of vascular depression, hypothesizing a positive effect in both depressive symptoms and cognitive functions. METHODS: We enrolled 93 inpatients over 60 years of age with a diagnosis of vascular depression. Depressive symptoms were weekly assessed (T0, T1, T2) with the 21-items Hamilton depression rating scale (HDRS). Cognitive functioning was evaluated with the Milan Overall Dementia Assessment (MODA) at baseline and after the treatment protocol. All patients were randomly assigned into three groups, Group I: one tDCS stimulation per day, Group II: two tDCS stimulations per day, Sham group: one sham tDCS stimulation per day. Stimulation was performed for 10 consecutive working days. RESULTS: A significant interaction time∗treatment was observed on HDRS scores (F = 14, p < 0.001). All groups improved at T1 but whereas Group II significantly differed from the Sham group (p < 0.001) we observed no difference between Sham and Group I. At T2 all groups improved but Group II showed the greater improvement (vs. Sham p < 0.001; vs. Group I p < 0.001) and the Sham group the smallest (vs. Group I p = 0.005). A significant interaction time∗treatment was also observed on MODA scores (F = 3.31, p = 0.04). Only subjects treated with tDCS improved at T2 (Group I: p < 0.001; Group II: p = 0.007). However, no difference between Group I and II was shown. CONCLUSION: tDCS as augmentation treatment of an adequate pharmacotherapy is a potential strategy in the management of vascular depression, a disease known to be often unresponsive to antidepressants only. Non-invasiveness, the absence of severe side effects and the possibility of administering it to outpatients at an affordable price make tDCS an important tool in clinical practice.

Spontaneous Coronary Artery Dissection: JACC State-of-the-Art Review.

Over the past decade, spontaneous coronary artery dissection (SCAD) has emerged as an important cause of myocardial infarction, particularly among younger women. The pace of knowledge acquisition has been rapid, but ongoing challenges include accurately diagnosing SCAD and improving outcomes. Many SCAD patients experience substantial post-SCAD symptoms, recurrent SCAD, and psychosocial distress. Considerable uncertainty remains about optimal management of associated conditions, risk stratification and prevention of complications, recommendations for physical activity, reproductive planning, and the role of genetic evaluations. This review provides a clinical update on the diagnosis and management of patients with SCAD, including pregnancy-associated SCAD and pregnancy after SCAD, and highlight high-priority knowledge gaps that must be addressed.

Factors Associated With Medication Adherence in Vascular Surgery Patients.

INTRODUCTION: Patients with vascular disease have higher mortality rates than age-matched peers and medical management of coexisting diseases may alter these outcomes. We sought to understand factors associated with medication nonadherence in vascular surgery patients at a single University vascular surgery clinic over a 3-month period. MATERIALS AND METHODS: Consecutive vascular surgery patients were surveyed from June to August 2019. The survey included demographic questions, the validated Morisky Medication Adherence Scale, the 4-item Patient Health Questionnaire for Anxiety and Depression scales, and other medication-related questions. Medical and surgical histories were retrospectively collected from charts. Univariate and multivariate analyses were used to compare among high, intermediate, and low adherence. RESULTS: A total of 128 (74%) of 174 patients met study inclusion criteria. On univariate analysis, lower medication adherence was associated with younger age (P = .004), anxiety and depression (P = .001), higher daily pain (P < .001), and patients who believed their medications were less important for treating their vascular disease (P < .001). Adherence was not associated with symptomatic vascular disease, gender, education level, marital status, employment, insurance, or the use of medication usage reminders. Multivariate analysis significantly predicted high adherence relative to low adherence with 5-year increase in age (odds ratio [OR] = 1.252, P = .021) and low adherence relative to high adherence with greater perceived pain (OR = 0.839, P = .016). CONCLUSIONS: Younger age and high level of pain were associated with lower medication adherence. Informing patients of the importance of prescribed medication and addressing anxiety or depression symptoms may improve adherence.

Evaluation of neurological effects of cerium dioxide nanoparticles doped with different amounts of zirconium following inhalation exposure in mouse models of Alzheimer's and vascular disease.

Increasing evidence from toxicological and epidemiological studies indicates that the brain is an important target for ambient (ultrafine) particles. Disturbance of redox-homeostasis and inflammation in the brain are proposed as possible mechanisms that can contribute to neurotoxic and neurodegenerative effects. Whether and how engineered nanoparticles (NPs) may cause neurotoxicity and promote neurodegenerative diseases such as Alzheimer's disease (AD) is largely unstudied. We have assessed the neurological effects of subacute inhalation exposures (4 mg/m3 for 3 h/day, 5 days/week for 4 weeks) to cerium dioxide (CeO2) NPs doped with different amounts of zirconium (Zr, 0%, 27% and 78%), to address the influence of particle redox-activity in the 5xFAD transgenic mouse model of AD. Four weeks post-exposure, effects on behaviour were evaluated and brain tissues were analysed for amyloid-ß plaque formation and reactive microglia (Iba-1 staining). Behaviour was also evaluated in concurrently exposed non-transgenic C57BL/6J littermates, as well as in Western diet-fed apolipoprotein E-deficient (ApoE-/-) mice as a model of vascular disease. Markers of inflammation and oxidative stress were evaluated in brain cortex. The brains of the NP-exposed 5xFAD mice revealed no accelerated amyloid-ß plaque formation. No significant treatment-related behaviour impairments were observed in the healthy C57BL/6J mice. In the 5xFAD and ApoE-/- models, the NP inhalation exposures did not affect the alternation score in the X-maze indicating absence of spatial working memory deficits. However, following inhalation exposure to the 78% Zr-doped CeO2 NPs changes in forced motor performance (string suspension) and exploratory motor activity (X-maze) were observed in ApoE-/- and 5xFAD mice, respectively. Exposure to the 78% doped NPs also caused increased cortical expression of glial fibrillary acidic protein (GFAP) in the C57BL/6J mice. No significant treatment-related changes neuroinflammation and oxidative stress were observed in the 5xFAD and ApoE-/- mice. Our study findings reveal that subacute inhalation exposure to CeO2 NPs does not accelerate the AD-like phenotype of the 5xFAD model. Further investigation is warranted to unravel whether the redox-activity dependent effects on motor activity as observed in the mouse models of AD and vascular disease result from specific neurotoxic effects of these NPs.

Analysis of Posttraumatic Stress Disorder, Depression, Anxiety, and Resiliency Within the Unique Population of Spontaneous Coronary Artery Dissection Survivors.

Background Mental health after spontaneous coronary artery dissection (SCAD), a cause of myocardial infarction in young women, remains largely unexplored. We assessed the prevalence and severity of psychiatric symptoms after SCAD. Methods and Results Individuals with confirmed SCAD who consented to the Mayo Clinic "Virtual" Multicenter SCAD Registry were sent the Posttraumatic Stress Disorder Diagnostic Scale for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, Anxiety Sensitivity Index, Connor-Davidson Resilience Scale, 36-Item Short-Form Health Survey, and an SCAD-specific questionnaire. Among 782 patients contacted, 512 surveys were returned. Most respondents were women (97.5%), with median age at time of SCAD and survey completion of 47 and 52 years, respectively. Eighty-two percent had at least one trauma, with mild or more posttraumatic stress disorder symptoms in 28%. Symptoms of anxiety and depression were observed in 41% and 32%, respectively. On multivariable analysis, those of younger age at first SCAD and low resiliency scored higher on measures of trauma, anxiety, and depression. Those with higher anxiety sensitivity had more severe anxiety and posttraumatic stress disorder symptoms. Emotional and social quality of life was higher in those with high resiliency scores. Time from SCAD event to survey completion was associated with lower Generalized Anxiety Disorder-7 score severity. Conclusions Survivors of SCAD have significant rates of posttraumatic stress disorder, depression, and anxiety, which are associated with lower quality of life specifically among those with lower resiliency. Given the prevalence and potential impact, screening and treatment for the psychological distress is advised. Behavioral interventions targeted toward resiliency training may be beneficial for this patient population.

Association of Vascular Risk Factors With ß-Amyloid Peptide and Tau Burdens in Cognitively Unimpaired Individuals and Its Interaction With Vascular Medication Use.

Importance: Vascular risk factors are associated with increased risk of Alzheimer disease (AD), but it is unclear whether there is a direct association of these risk factors with AD pathogenesis. Objectives: To assess the associations of vascular risk factors with AD pathogenesis in asymptomatic individuals, and to test whether this association is moderated among individuals who use vascular medications. Design, Setting, and Participants: This cross-sectional study used data from the Presymptomatic Evaluation of Experimental or Novel Treatments for Alzheimer Disease (PREVENT-AD) cohort of cognitively unimpaired individuals aged 55 to 82 years with a parental or multiple-sibling history of sporadic AD, who were recruited via advertisement from the greater Montreal, Quebec, Canada, metropolitan area. Participants were enrolled between September 9, 2011, to May, 3, 2017, and stratified by use vs no use of vascular medications. Data were analyzed July 1, 2018, to April 5, 2019. Main Outcomes and Measures: Principal analyses investigated associations of total, high-density lipoprotein, and low-density lipoprotein cholesterol levels, systolic and diastolic blood pressure, pulse pressure, and a combined vascular risk score (measured using the Framingham Coronary Risk Profile) with global ß-amyloid peptide (Aß) and entorhinal tau burden as measured by positron emission tomography (PET). Potential moderating associations of use of vascular medications with these associations were examined. Secondary similar analyses considered cerebrospinal fluid (CSF) Aß1-42 and phosphorylated tau levels. Results: Among 215 participants (mean [SD] age, 62.3 [5.0] years; 161 [74.8%] women), 120 participants underwent PET, including 75 participants (62.5%) who were not using vascular medications, and 162 participants underwent CSF assessment, including 113 participants (69.8%) who were not using vascular medications. There was an overlap of 67 participants who underwent PET and CSF assessment. Interaction analyses showed that among participants not using vascular medications, higher Aß deposition as measured by PET was associated with higher total cholesterol level (ß = -0.002 [SE, 0.001]; P = .02), low-density lipoprotein cholesterol level (ß = -0.002 [SE, 0.001]; P = .006), systolic blood pressure (ß = -0.006 [SE, 0.002]; P = .02), pulse pressure (ß = -0.007 [SE, 0.002]; P = .004), and Framingham Coronary Risk Profile score (ß = -0.038 [SE, 0.011]; P = .001), but such associations were absent in participants who used vascular medications. Interactions were also found between vascular medication use and high-density lipoprotein cholesterol (ß = -3.302 [SE, 1.540]; P = .03), low-density lipoprotein cholesterol (ß = 1.546 [SE, 0.754]; P = .04), and Framingham Coronary Risk Profile score (ß = 23.102 [SE, 10.993]; P = .04) on Aß1-42 burden as measured in CSF. Higher Framingham Coronary Risk Profile scores were associated with reduced tau burden among participants using vascular medications but not among participants not using vascular medications (interaction, ß = -0.010 [SE, 0.005]; P = .046). Conclusions and Relevance: These findings corroborate previously reported associations of vascular risk factors with Aß burden but not tau burden. However, these associations were found only among individuals who were not using vascular medications. These results suggest that medication use or other control of vascular risk factors should be considered in Alzheimer disease prevention trials.

Cognition in Vascular Aging and Mild Cognitive Impairment.

Cardiovascular health declines with age, due to vascular risk factors, and this leads to an increasing risk of cognitive decline. Mild cognitive impairment (MCI) is defined as the negative cognitive changes beyond what is expected in normal aging. The purpose of the study was to compare older adults with vascular risk factors (VRF), MCI patients, and healthy controls (HC) in main dimensions of cognitive control. The sample comprised a total of 109 adults, aged 50 to 85 (M = 66.09, S.D. = 9.02). They were divided into three groups: 1) older adults with VRF, 2) MCI patients, and 3) healthy controls (HC). VRF and MCI did not differ significantly in age, educational level, or gender as was the case with HC. The tests used mainly examine inhibition, cognitive flexibility, and working memory processing. Results showed that the VRF group had more Set Loss Errors in drawing designs indicating deficits in establishing cognitive set and in cognitive shifting. MCI patients displayed lower performance in processing. Hence, different types of specific impairments emerge in vascular aging and MCI, and this may imply that discrete underlying pathologies may play a role in the development of somewhat different profiles of cognitive decline.

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.

Patient-Reported Psychological Distress After Spontaneous Coronary Artery Dissection: EVIDENCE FOR POST-TRAUMATIC STRESS.

PURPOSE: High rates of depression and anxiety are reported among patients who have experienced spontaneous coronary artery dissection (SCAD) but the incidence of post-traumatic stress disorder (PTSD) is unknown. The purpose of this study was to investigate symptoms of PTSD in women who have experienced SCAD. METHODS: This cross-sectional pilot study included 14 female SCAD patients, mean age of 51 yr, who responded to standardized psychosocial questionnaires at a median of 35 mo post-SCAD. Patients were identified by cardiologists as having had a SCAD event and were concurrently invited to participate in a psychosocial group for SCAD survivors. RESULTS: Participants reported current symptoms of stress (93%), insomnia (57%), anxiety (71%), depression (36%), and PTSD (43%). Eight of the 11 women who reported having a mental health history (72.7%) indicated that their symptoms were related to having experienced SCAD. Health-related quality of life and social support were comparable with other all-female cardiac samples. Patterns of perceived control were more similar to those of patients with cancer than other cardiac patients in that SCAD patients ranked "chance" as more likely than "self-control" to impact medical outcomes. CONCLUSIONS: The prevalence of PTSD symptoms in this first-known assessment of post-traumatic stress among SCAD patients is concerning. The unexpected nature of SCAD and lack of known treatment options may play a role in patient distress. Future research is needed to accurately estimate rates of PTSD after SCAD and assess the benefits of treatment.

Metabolic risk in older adults is associated with impaired sustained attention.

OBJECTIVE: Metabolic syndrome (MetS), the presence of three or more cardiovascular risk factors, has been associated with subtle and diffuse neural compromise but has not been consistently associated with cognitive dysfunction. Sustained attention is a fundamental cognitive operation that relies on multiple brain networks and is impaired in a broad array of neurologic conditions. We examined whether a well-validated measure of sustained attention would be sensitive to vascular risk, as compared with more standard neuropsychological measures of attention and executive functioning. METHOD: We assessed vascular risk factors (VRFs; blood pressure, waist circumference, cholesterol, glucose, and triglycerides) in 93 middle-to-older aged adults (45-75 years). MetS was defined based on current guidelines from the National Cholesterol Education Program Adult Training Program (NCEP ATP III). Participants were grouped according to number of VRFs: high risk (MetS; 3+ VRFs; N = 32), medium risk (1 or 2 VRFs; N = 35), and low risk (0 VRFs; N = 26). All participants underwent a neuropsychological battery of tests measuring executive functioning. Participants also performed the gradual-onset continuous performance task (gradCPT), a measure of sustained attention. RESULTS: There was a significant main effect of VRF group on sustained attention performance; participants with lower vascular risk were better able to sustain attention. No significant effects were detected on standard neuropsychological tests of executive function. CONCLUSION: Our results suggest that the gradCPT is sensitive to the potentially negative effects of MetS on subtle aspects of neurocognitive functioning.

The Seriousness of Chronic Venous Disease: A Review of Real-World Evidence.

Chronic venous disease (CVD) is a prevalent condition that tends to worsen with age. Patients initially seek treatment to relieve symptoms of leg pain, discomfort, heaviness and swelling, all of which impact their quality of life. As the disease increases in severity to include varicose veins, skin changes, and venous ulcer, the demand for treatment increases while the quality of life further diminishes. The prevalence of CVD is highest in Western countries where it already consumes up to 2% of healthcare budgets. With the aging of the global population, the prevalences of CVD and severe CVD are projected to increase substantially, foretelling unsustainably large increases in the healthcare resources and costs needed to treat CVD patients in the coming decades. Effective venoactive drug treatments and ablation procedures are available that provide symptom relief, improve quality of life, slow disease progression, and promote ulcer healing. In addition, venoactive drug treatments may be highly cost-effective. However, there is evidence that physician awareness of CVD is suboptimal and that many patients with CVD are not being treated or referred to specialists according to established guidelines. To decrease this treatment gap and prevent unnecessary disease progression, international guidelines are available to help physicians consider CVD treatment options and refer patients when warranted. Improved disease awareness and appropriate early treatment may help reduce the coming burden of CVD.Funding: Servier.

Impact of Vascular Disease, Amputation Level, and the Mismatch Between Balance Ability and Balance Confidence in a Cross-Sectional Study of the Likelihood of Falls Among People With Limb Loss: Perception Versus Reality.

OBJECTIVE: The aim of the study was to investigate the impact of balance ability, activities-specific balance confidence, and other self-reported and clinical factors on incidence of falls among people with lower limb loss. DESIGN: This is a cross-sectional study (N = 305) with multivariable logistic regression analysis. RESULTS: Participants included 68.3% men with an age of 55.5 ± 14.9, with 50% dysvascular and 56.8% transtibial amputations. The mean ± SD activities-specific balance confidence is 2.1/4 ± 1.1, balance ability is 2.9/4 ± 1.3, and walking speed is 0.766 ± 0.387 m/sec. The final model showed fall risk was heightened for people with vascular comorbidities (odds ratio = 3.46, 95% confidence interval = 1.40-8.54) and better balance (odds ratio = 23.29, confidence interval = 3.19-170.23), but attenuated for people with transfemoral (odds ratio = 0.08, confidence interval = 0.01-0.82) and vascular amputations (odds ratio = 0.38, confidence interval = 0.15-0.95). Significant interactions existed between age and amputation level (odds ratio = 1.06, confidence interval = 1.02-1.11) and between balance confidence and balance ability (odds ratio = 0.27, confidence interval = 0.13-0.57). CONCLUSIONS: Although people with vascular amputations were less likely to fall than those with nonvascular amputations, people with concurrent vascular comorbidities were more likely to fall than those without. People with transfemoral amputations were less likely to fall; however, fall risk increased with each year of age compared with people with transtibial amputations. People with balance ability of 3.5 or greater fell more often than those with lower ability, but people with lower balance ability and mismatched confidence in their balance ability had 3.7 times greater fall risk.
