Computed tomography myocardial perfusion imaging to detect myocardial ischemia in patients with anxiety and obstructive coronary heart disease post-exposure to mental stressors.

This study aims to measure myocardial blood flow (MBF) using dynamic CT- myocardial perfusion imaging (CT-MPI) combined with mental stressors in patients with obstructive coronary artery disease (OCAD) and in patients with anxiety and no obstructive coronary artery disease (ANOCAD). A total of 30 patients with OCAD with 30 patients with ANOCAD were included in this analysis. Using the 17-segment model, the rest and stress phase MBF of major coronary arteries in participants were recorded respectively. Compared with ANOCAD patients, OCAD patients were more likely to have localized reduction of MBF (p < 0.05). For patients with ANOCAD, both global MBF and MBF of the main coronary arteries in the stress phase were lower than those in the rest phase (all p < 0.05), but there was no significant difference in MBF among the main coronary arteries in the rest or stress phase (p = 0.25, p = 0.15). For patients with OCAD, the MBF of the target area was lower than that of the non-target area in both the rest and stress phase, and the MBF of the target area in the stress phase was lower than that in the rest phase (all p < 0.05). However, there was no significant difference in MBF between the rest or stress phase in the non-target area (p = 0.73). Under mental stress, the decrease in MBF in ANOCAD patients was diffuse, while the decrease in MBF in OCAD patients was localized. Dynamic CT-MPI combined with mental stressors can be used to detect MBF changes in anxiety patients.

Improving mental health in chronic care in general practice: study protocol for a cluster-randomised controlled trial of the Healthy Mind intervention.

BACKGROUND: Mental health issues are common among patients with chronic physical conditions, affecting approximately one in five patients. Poor mental health is associated with worse disease outcomes and increased mortality. Problem-solving therapy (PST) may be a suitable treatment for targeting poor mental health in these patients. This study protocol describes a randomised controlled trial of the Healthy Mind intervention, a general practice-based intervention offering PST to patients with type 2 diabetes and/or ischaemic heart disease and poor mental well-being. METHODS: A stepped-wedge cluster-randomised controlled trial with 1-year follow-up will be conducted in Danish general practice. At the annual chronic care consultation, patients with type 2 diabetes and/or chronic ischaemic heart disease will be screened for poor mental well-being. Patients in the control group will be offered usual care while patients in the intervention group will be offered treatment with PST provided by general practitioners (GPs) or general practice staff, such as nurses, who will undergo a 2-day PST course before transitioning from the control to the intervention group. The primary outcome is change in depressive symptoms after 6 and 12 months. Secondary outcomes include change in mental well-being, anxiety, and diabetes distress (patients with type 2 diabetes) after 6 and 12 months as well as change in total cholesterol levels, low-density lipoprotein (LDL) levels, and blood glucose levels (patients with diabetes) after 12 months. Process outcomes include measures of implementation and mechanisms of impact. We aim to include a total of 188 patients, corresponding to approximately 14 average-sized general practices. DISCUSSION: The Healthy Mind trial investigates the impact of PST treatment for patients with chronic disease and poor mental well-being in general practice. This will be the first randomised controlled trial determining the effect of PST treatment for patients with chronic diseases in general practice. The results of this study will provide relevant insights to aid GPs, and general practice staff manage patients with poor mental well-being. TRIAL REGISTRATION: ClinicalTrials.gov NCT05611112.

Psychometric Evaluation of the Mandarin HeartQoL Health-Related Quality of Life Questionnaire Among Patients With Ischemic Heart Disease in China.

OBJECTIVES: This study evaluated the psychometric properties of the Mandarin version of the HeartQoL questionnaire, a core ischemic heart disease (IHD) health-related quality of life (HRQL) instrument, in patients with angina, myocardial infarction (MI), and ischemic heart failure (IHF). METHODS: The English version of HeartQoL was translated into Mandarin. A cross-sectional study was then conducted in mainland China using the Mandarin HeartQoL, Short Form-12 Health Survey, and Hospital Anxiety and Depression Scale. Factor analysis was used to establish the HeartQoL structure and internal consistency reliability and construct validity were assessed. RESULTS: Patients with IHD (n = 412; angina = 112, MI = 151, and IHF = 149) were enrolled. Significantly higher HeartQoL HRQL scores were reported by patients with either angina or MI than by patients with IHF. The 2-factor structure was confirmed by Mokken scale analysis in the total group with strong H coefficients on the global scale (0.64) and both the physical (0.70) and emotional (0.80) subscales. Internal consistency reliability was strong with Cronbach's α ranging from 0.90 to 0.95. Convergent validity was confirmed with strong correlations between similar physical and mental HeartQoL and Short Form-12 Health Survey subscales ranging from 0.77 to 0.82 with divergent validity confirmed with significantly lower correlations between dissimilar constructs. Discriminative validity was confirmed for 72% of the a priori sociodemographic and clinical hypotheses. CONCLUSIONS: The Mandarin version of the HeartQoL HRQL questionnaire demonstrates acceptable internal consistency reliability and convergent, divergent, and discriminative validity in patients with IHD and in each diagnostic subgroup. The data support the use of the HeartQoL to assess and compare HRQL in Mandarin-speaking patients with IHD.

Facial Emotion Expression and the Inducibility of Myocardial Ischemia During Cardiac Stress Testing: The Role of Psychological Background Factors.

OBJECTIVE: Negative emotional states, such as anger and anxiety, are associated with the onset of myocardial infarction and other acute clinical manifestations of ischemic heart disease. The likelihood of experiencing these short-term negative emotions has been associated with long-term psychological background factors such as depression, generalized anxiety, and personality factors. We examined the association of acute emotional states preceding cardiac stress testing (CST) with inducibility of myocardial ischemia and to what extent psychological background factors account for this association. METHODS: Emotional states were assessed in patients undergoing CST (n = 210; mean [standard deviation] age = 66.9 [8.2] years); 91 (43%) women) using self-report measures and video recordings of facial emotion expression. Video recordings were analyzed for expressed anxiety, anger, sadness, and happiness before CST. Psychological background factors were assessed with validated questionnaires. Single-photon emission computed tomography was used to evaluate inducibility of ischemia. RESULTS: Ischemia occurred in 72 patients (34%). Emotional states were not associated with subsequent inducibility of ischemia during CST (odds ratio between 0.93 and 1.04; p values > .50). Psychological background factors were also not associated with ischemia (odds ratio between 0.96 and 1.06 per scale unit; p values > .20) and did not account for the associations of emotional states with ischemia. CONCLUSIONS: Emotional states immediately before CST and psychological background factors were not associated with the inducibility of ischemia. These findings indicate that the well-documented association between negative emotions with acute clinical manifestations of ischemic heart disease requires a different explanation than a reduced threshold for inducible ischemia.

Association of Mental Stress-Induced Myocardial Ischemia With Cardiovascular Events in Patients With Coronary Heart Disease.

Importance: Mental stress-induced myocardial ischemia is a recognized phenomenon in patients with coronary heart disease (CHD), but its clinical significance in the contemporary clinical era has not been investigated. Objective: To compare the association of mental stress-induced or conventional stress-induced ischemia with adverse cardiovascular events in patients with CHD. Design, Setting, and Participants: Pooled analysis of 2 prospective cohort studies of patients with stable CHD from a university-based hospital network in Atlanta, Georgia: the Mental Stress Ischemia Prognosis Study (MIPS) and the Myocardial Infarction and Mental Stress Study 2 (MIMS2). Participants were enrolled between June 2011 and March 2016 (last follow-up, February 2020). Exposures: Provocation of myocardial ischemia with a standardized mental stress test (public speaking task) and with a conventional (exercise or pharmacological) stress test, using single-photon emission computed tomography. Main Outcomes and Measures: The primary outcome was a composite of cardiovascular death or first or recurrent nonfatal myocardial infarction. The secondary end point additionally included hospitalizations for heart failure. Results: Of the 918 patients in the total sample pool (mean age, 60 years; 34% women), 618 participated in MIPS and 300 in MIMS2. Of those, 147 patients (16%) had mental stress-induced ischemia, 281 (31%) conventional stress ischemia, and 96 (10%) had both. Over a 5-year median follow-up, the primary end point occurred in 156 participants. The pooled event rate was 6.9 per 100 patient-years among patients with and 2.6 per 100 patient-years among patients without mental stress-induced ischemia. The multivariable adjusted hazard ratio (HR) for patients with vs those without mental stress-induced ischemia was 2.5 (95% CI, 1.8-3.5). Compared with patients with no ischemia (event rate, 2.3 per 100 patient-years), patients with mental stress-induced ischemia alone had a significantly increased risk (event rate, 4.8 per 100 patient-years; HR, 2.0; 95% CI, 1.1-3.7) as did patients with both mental stress ischemia and conventional stress ischemia (event rate, 8.1 per 100 patient-years; HR, 3.8; 95% CI, 2.6-5.6). Patients with conventional stress ischemia alone did not have a significantly increased risk (event rate, 3.1 per 100 patient-years; HR, 1.4; 95% CI, 0.9-2.1). Patients with both mental stress ischemia and conventional stress ischemia had an elevated risk compared with patients with conventional stress ischemia alone (HR, 2.7; 95% CI, 1.7-4.3). The secondary end point occurred in 319 participants. The event rate was 12.6 per 100 patient-years for patients with and 5.6 per 100 patient-years for patients without mental stress-induced ischemia (adjusted HR, 2.0; 95% CI, 1.5-2.5). Conclusions and Relevance: Among patients with stable coronary heart disease, the presence of mental stress-induced ischemia, compared with no mental stress-induced ischemia, was significantly associated with an increased risk of cardiovascular death or nonfatal myocardial infarction. Although these findings may provide insights into mechanisms of myocardial ischemia, further research is needed to assess whether testing for mental stress-induced ischemia has clinical value.

Investigating Rurality as a Risk Factor for State and Trait Hopelessness in Hospitalized Patients With Ischemic Heart Disease.

Background Rurality and hopelessness are each associated with increased mortality in adults with ischemic heart disease (IHD), yet there is no known research examining rurality as a risk factor for hopelessness in patients with IHD. This study evaluated rurality as a risk factor for state and trait hopelessness in adults hospitalized with IHD in samples drawn from the Great Lakes and Great Plains regions of the United States. Methods and Results A descriptive cross-sectional design was used. Data were collected from 628 patients hospitalized for IHD in the Great Lakes (n=516) and Great Plains (n=112). Rural-Urban Commuting Area codes were used to stratify study participants by level of rurality. Levels of state hopelessness (measured by the State-Trait Hopelessness Scale) were higher in rural patients (58.8% versus 48.8%; odds ratio [OR], 1.50; 95% CI, 1.03-2.18), a difference that remained statistically significant after adjusting for demographics, depression severity (measured by the Patient Health Questionnaire-8), and physical functioning (measured by the Duke Activity Status Index; OR, 1.59; 95% CI, 1.06-2.40; P=0.026). There was evidence of an interaction between marital status and rurality on state hopelessness after accounting for covariates (P=0.02). Nonmarried individuals had an increased prevalence of state hopelessness (nonmarried 72.0% versus married 52.0%) in rural areas (P=0.03). Conclusions Rural patients with IHD, particularly those who are nonmarried, may be at higher risk for state hopelessness compared with patients with IHD living in urban settings. Understanding rurality differences is important in identifying subgroups most at risk for hopelessness. Registration URL: http://www.clinicaltrials.gov. Unique identifier: NCT04498975.

An analysis of anxiety and selected aspects of personality in women with ischemic heart disease according to P.T. Costa and R. R. McCrae theory - The role of psychosocial factors in ischemic heart disease.

INTRODUCTION: Risk factors for ischemic heart disease (IHD) are very numerous and not fully defined. In addition to classic risk factors, different factors are also distinguished, among them psychological aspects chich have rarely been subject to detailed analyses. OBJECTIVE: The aim of study was an analysis of the anxiety structure, including the five factors of personality: neuroticism (NEU), extraversion (EXT), openness (OPE), agreeableness (AGR) and conscientiousness (CON), in women with IHD. MATERIAL AND METHODS: The study involved 140 women aged 37-74 years with IHD confirmed by coronary angiography. Psychological examination was conducted using R.B. Cattell's IPAT Anxiety Scale and P.T. Costa and R.R. McCrae's NEO-FFI Personality Inventory. RESULTS: The results obtained from the IPAT Anxiety Scale showed that the study group of 140 women with IHD had the correct level of internal integrity (Q3- ). The dominant factor in the anxiety structure in 88.7% of subjects was neurotic tension (Q4+). A lack of sense of safety was indicated by 72.6% of subjects (L+), 69.3% experienced a strong tendency to self-blame and experience a sense of guilt (O + ), and over 51.6% of women with IHD expressed decreased emotional stability (C - ). The level of general anxiety was high (GA=7.3). The analysis of the five factors of personality revealed that the dominant factors in the structure of personality of women with IHD were CON in 69.3%, AGR in 46.7% and EXT in 45.2%. NEU and OPE were moderately significant factors. CONCLUSIONS: Women with IHD are characterised by a high level of anxiety, increased neurotic tension, decreased emotional stability, auto-aggression and a sense of danger and distrust. Women with IHD demonstrate a high level of factors, such as extraversion, agreeableness and conscientiousness.

Heart up! RCT protocol to increase physical activity in cardiac patients who report hopelessness: Amended for the COVID-19 pandemic.

Hopelessness is associated with decreased physical activity (PA) and increased adverse events and death in patients with ischemic heart disease (IHD). Rates of PA in patients with IHD continue to be low in both hospital-based cardiac rehabilitation and home settings. While researchers have investigated strategies to increase PA among patients with IHD, interventions to promote PA specifically in IHD patients who report hopelessness are lacking. We describe the protocol for a NIH-funded randomized controlled trial designed to establish the effectiveness of a 6-week intervention (Heart Up!) to promote increased PA in IHD patients who report hopelessness. Participants (n = 225) are randomized to one of three groups: (1) motivational social support (MSS) from a nurse, (2) MSS from a nurse plus significant other support (SOS), or (3) attention control. Aims are to: (1) test the effectiveness of 6 weeks of MSS and MSS with SOS on increasing mean minutes per day of moderate to vigorous PA; (2) determine the effects of change in moderate to vigorous PA on hopelessness; and (3) determine if perceived social support and motivation (exercise self-regulation) mediate the effects of the intervention on PA. A total of 69 participants have been enrolled to date. The protocol has been consistently and accurately used by research personnel. We address the protocol challenges presented by the COVID-19 pandemic and steps taken to maintain fidelity to the intervention. Findings from this study could transform care for IHD patients who report hopelessness by promoting self-management of important PA goals that can contribute to better health outcomes.

Efficacy and cost-effectiveness of a therapist-assisted web-based intervention for depression and anxiety in patients with ischemic heart disease attending cardiac rehabilitation [eMindYourHeart trial]: a randomised controlled trial protocol.

BACKGROUND: One in five patients with ischaemic heart disease (IHD) develop comorbid depression or anxiety. Depression is associated with risk of non-adherence to cardiac rehabilitation (CR) and dropout, inadequate risk factor management, poor quality of life (QoL), increased healthcare costs and premature death. In 2020, IHD and depression are expected to be among the top contributors to the disease-burden worldwide. Hence, it is paramount to treat both the underlying somatic disease as well as depression and anxiety. eMindYourHeart will evaluate the efficacy and cost-effectiveness of a therapist-assisted eHealth intervention targeting depression and anxiety in patients with IHD, which may help fill this gap in clinical care. METHODS: eMindYourHeart is a multi-center, two-armed, unblinded randomised controlled trial that will compare a therapist-assisted eHealth intervention to treatment as usual in 188 CR patients with IHD and comorbid depression or anxiety. The primary outcome of the trial is symptoms of depression, measured with the Hospital Anxiety and Depression Scale (HADS) at 3 months. Secondary outcomes evaluated at 3, 6, and 12 months include symptoms of depression and anxiety (HADS), perceived stress, health complaints, QoL (HeartQoL), trial dropout (number of patients dropped out in either arm at 3 months) and cost-effectiveness. DISCUSSION: To our knowledge, this is the first trial to evaluate both the efficacy and cost-effectiveness of a therapist-assisted eHealth intervention in patients with IHD and comorbid psychological distress as part of CR. Integrating screening for and treatment of depression and anxiety into standard CR may decrease dropout and facilitate better risk factor management, as it is presented as "one package" to patients, and they can access the eMindYourHeart program in their own time and at their own convenience. The trial holds a strong potential for improving the quality of care for an increasing population of patients with IHD and comorbid depression, anxiety or both, with likely benefits to patients, families, and society at large due to potential reductions in direct and indirect costs, if proven successful. Trial registration The trial was prospectively registered on https://clinicaltrials.gov/ct2/show/NCT04172974 on November 21, 2019 with registration number [NCT04172974].

Anxiety and hemodynamic reactivity during cardiac stress testing: The role of gender and age in myocardial ischemia.

BACKGROUND: The prevalence of myocardial ischemia is associated with anxiety. State and trait anxiety are more common in younger women compared to men, and high anxiety levels could affect hemodynamic reactivity during cardiac stress testing. The aim is to examine whether anxiety plays a role in gender differences in patients ≤ 65 and > 65 years in hemodynamic reactivity and ischemia during cardiac stress testing. METHODS AND RESULTS: Included were 291 patients (66.8 ± 8.7 years, 45% women) with suspect ischemia undergoing myocardial perfusion single-photon emission computed tomography (MPI-SPECT). Primary outcomes were semi-quantitative summed difference score (SDS) and summed stress score (SSS), as continuous indicators of myocardial ischemia. Analyses were stratified by age. Trait anxiety was measured using a validated questionnaire (GAD-7) and state anxiety using facial expression analyses software. Overall, trait and state anxiety were not associated with the prevalence of ischemia (N = 107, 36%). A significant interaction was found between gender and trait anxiety in women ≤ 65 years for SDS (F(1,4) = 5.73, P = .019) and SSS (F(1,10) = 6.50, P = .012). This was not found for state anxiety. CONCLUSION: SDS and SSS were significantly higher in women younger than 65 years with high trait anxiety. This interaction was not found in men and women over 65 years.

Mental stress-induced myocardial ischemia and cognitive impairment in coronary atherosclerosis.

OBJECTIVE: To understand if presence of mental stress-induced myocardial ischemia (MSIMI) is associated with higher prevalence of cognitive impairment at baseline and its decline over time. METHODS: A cohort of participants with stable coronary atherosclerosis underwent acute mental stress testing using a series of standardized speech/arithmetic stressors. The stress/rest digital vasomotor response to mental stress (sPAT) was assessed to measure microvascular constriction during mental stress. Patients received 99mTc-sestamibi myocardial perfusion imaging at rest, with mental stress and with conventional (exercise/pharmacological) stress. Cognitive function was assessed both at baseline and at a 2 year follow-up using the Trail Making Test parts A and B and the verbal and visual memory subtests of the Wechsler Memory Scale. RESULTS: We studied 486 individuals (72% male, 32.1% Black, 62 ± 9 (mean ± SD) years old). After multivariable adjustment for baseline demographics, risk factors, and medication use, presence of MSIMI was associated with 21% and 20% slower completion of Trail-A and Trail-B, respectively (p for all <0.01). After a 2-year follow-up period, presence of MSIMI was associated with a 33% slower completion of Trail-B, denoting cognitive decline (B = 0.33, 95% CI, 0.04, 0.62). A lower sPAT, indicating greater vasoconstriction, mediated the association between MSIMI and worsening Trail-B performance by 18.2%. Ischemia with a conventional stress test was not associated with any of the cognitive tests over time. CONCLUSION: MSIMI is associated with slower visuomotor processing and worse executive function at baseline and with greater decline in these abilities over time.

Differential Diagnosis, Clinical Characteristics, and Interventions of Braid-Like Coronary Artery: Case Series Analysis Based on Optical Coherence Tomography.

AIM: Based on optical coherence tomography (OCT), we aimed to determine the diagnosis, clinical characteristics, and interventions of braid-like coronary arteries, which are rare and tend to be diagnosed as a woven coronary artery (WCA) anomaly. METHODS AND RESULTS: We identified braid-like lesions on coronary angiography (CAG) in 7 patients (6 men; median age 47 years; age range 26 to 57 years). All patients were heavy smokers. Four patients were diagnosed with an old myocardial infarction and the other 3 with unstable angina. The braid-like lesions were located in the left anterior descending arteries in 2 patients and in the right coronary arteries in the other 5. TIMI grade 2 flow was observed in all involved vessels. OCT findings of all lesions were consistent with recanalization of organized thrombi, which consisted of septa that divided the lumen into multiple small cavities communicating with each other. No separate three-layered structure could be defined. Based on the significance of the stenosis and its related symptoms, drug-eluting stents were implanted in all of the lesions. All patients experienced symptomatic improvement after the intervention and were followed up event-free for 12 months. CONCLUSIONS: Braid-like coronary arteries are likely to undergo recanalization of organized thrombi rather than WCA according to our OCT findings. The majority of cases affect men who smoke heavily. Percutaneous stent implantation may be beneficial in selected patients when feasible.

The impact of depression and anxiety in prognosis of patients undergoing myocardial perfusion imaging with 99mTc tetrofosmin SPECT for evaluation of possible myocardial ischemia.

BACKGROUND: The goal of this study was to evaluate the prevalence of depression and anxiety in patients subjected to myocardial perfusion imaging (MPI) with 99mTc tetrofosmin stress-rest single-photon emission computer tomography (SPECT), and their impact on their cardiological events or disease. MATERIAL AND METHODS: Patients referred to the Nuclear Medicine Department for 99mTc tetrofosmin myocardial MPI-SPECT were asked to fulfill the Zung Self-Rating Depression Scale (ZDS) and Hamilton anxiety questionnaire (HAQ). Among 213 patients who completed the ZDS and HAQ, 80 patients (59 males and 21 females) were selected for this study because they had no known psychological disease, other disease that could influence psychological status, or use of narcotic drugs. Collected data from MPI and psychological status were subsequently analyzed. RESULTS: Among all 80 patients, 52 patients (65%) had abnormal MPI of whom 28/52 (53.8%) exhibited either depression, anxiety or both, and 28 (35%) patients had normal MPI of whom 10/28 (35.7%) had abnormal psychological status. The higher number of patients with abnormal psychological status in association with abnormal MPI was noted predominantly in patients with previously established coronary artery disease. A correlation was also noted between obesity, cardiac heredity and depression or anxiety in patients with abnormal MPI. CONCLUSIONS: Patients that exhibit depression, anxiety, or both, have high rates of myocardial ischemia, and thus are at risk for subsequent cardiological events.

Mobile-Application-Based Interventions for Patients With Hypertension and Ischemic Heart Disease: A Systematic Review.

BACKGROUND: Hypertension and ischemic heart disease are major causes of adult mortality. Related interventions to manage these conditions are important to implement during long, symptom-free periods. The recent proliferation of smartphones has spawned numerous health interventions that rely on mobile applications. PURPOSE: This systematic review was designed to summarize and analyze research on interventions using mobile applications for patients with hypertension and ischemic heart disease. METHODS: We searched for related studies published from January 2006 to August 2017 on MEDLINE, EMBASE, CINAHL, and three Korean databases. Seventeen studies were identified and evaluated against eligibility criteria that included a focus on patients with hypertension or ischemic heart disease and a discussion of the detailed effects of a mobile-app-based intervention. All of the identified studies were evaluated qualitatively using a methodology checklist. RESULTS: Twelve of the 17 studies were deemed as of acceptable quality according to the Scottish Intercollegiate Guideline Network quality assessment. According to the National Institutes of Health quality assessment tool, one article was of fair quality and four articles were of poor quality. Monitoring, education, and reminders were identified as application interventions. The effects of the app interventions were analyzed according to physiological factors, cognitive and behavioral factors, and psychological factors. Of the seven studies that measured blood pressure in patients with hypertension, five studies reported that the app-based interventions reduced blood pressure. Two of three studies showed a significant decrease of body mass index in patients with ischemic heart disease after the app-based interventions compared to the control group. Five of seven studies reported a significant change in medication adherence. Several studies showed different outcomes according to the disease, but the limited number of eligible studies was insufficient to demonstrate a conclusive effect. CONCLUSIONS: To ensure the long-term effects of mobile-application-based interventions, healthcare professionals should consider the functions of mobile applications. Moreover, because the focus of these interventions may differ based on the nature of the disease, it is recommended that the composition of interventions be tailored to the specific disease.

Lack of perceived social support in patients with ischemic heart disease is associated with hopelessness.

OBJECTIVE: To evaluate perceived social support (PSS) in ischemic heart disease (IHD) patients who report hopelessness. METHODS: Using a cross-sectional design, 156 patients were screened during their hospitalization for moderate to severe state hopelessness. Twenty patients who reported hopelessness during hospitalization and maintained hopelessness one week after hospital discharge were included. RESULTS: A moderately strong negative correlation was identified between PSS and state hopelessness (r = -0.54, p = .014). PSS was significantly higher in married/partnered patients (26.7 ± 4.85) compared to unmarried/unpartnered patients (18 ± 9.18; t = 2.45, p = .035). CONCLUSIONS: Social support may help reduce hopelessness in vulnerable cardiac patients, especially those who are unpartnered.

Gender-Related Determinants of Adherence to the Mediterranean Diet in Adults with Ischemic Heart Disease.

BACKGROUND: The reasons behind low adherence to the Mediterranean diet (Med-diet) are still not entirely known. We aimed to evaluate the effect of biological (i.e., sex-related) and psycho-socio-cultural (i.e., gender-related) factors on Med-diet adherence. METHODS: Baseline Med-diet adherence was measured using a self-administered questionnaire among adults with ischemic heart disease (IHD) from the EVA (Endocrine Vascular Disease Approach) study. A multivariable analysis was performed to estimate the effect of sex- and gender-related factors (i.e., identity, roles, relations, and institutionalized gender) on low adherence. RESULTS: Among 366 participants (66 ± 11 years, 31% women), 81 (22%) adults with low adherence demonstrated higher rates of diabetes, no smoking habit, lower male BSRI (Bem Sex Role Inventory) (median (IQR) 4.8 (4.1 to 5.5) vs. 5.1 (4.5 to 5.6) and p = 0.048), and higher Perceived Stress Scale 10 items (PSS-10) (median (IQR) 19 (11 to 23) vs. 15 (11 to 20) and p = 0.07) scores than those with medium-high adherence. In the multivariable analysis, only active smoking (odds ratio, OR = 2.10, 95% confidence interval, CI 1.14 to 3.85 and p = 0.017), PPS-10 (OR = 1.04, 95% CI 1.00 to 1.08, and p = 0.038) and male BSRI scores (OR = 0.70, 95% CI 0.52 to 0.95, and p = 0.021) were independently associated with low adherence. CONCLUSIONS: Male personality traits and perceived stress (i.e., gender identity) were associated with low Med-diet adherence regardless of the sex, age, and comorbidities. Therefore, gender-sensitive interventions should be explored to improve adherence in IHD.

Sex and gender-stratified risks of psychological factors for adverse clinical outcomes in patients with ischemic heart disease: A systematic review and meta-analysis.

BACKGROUND: Psychological factors are associated with adverse prognosis in patients with ischemic heart disease (IHD). However, it is unknown whether these risk factors differ between women and men. METHODS: PubMed, EMBASE, and PsycINFO were searched to identify studies assessing the risk of psychological factors for major adverse cardiovascular events (MACE) in samples with IHD. Psychological factors included anger/hostility, anxiety, depression, psychological distress, social support, Type A behavior pattern, Type D personality, and Posttraumatic Stress Disorder (PTSD). RESULTS: A total of 44 articles (64 separate reports) including 227,647 women and 321,894 men reporting confounder-adjusted hazard ratios (HRs) or relative risks (RRs) were included in the primary analysis. Results based on random-effects models showed that the association between psychological factors (all combined) and MACE was stronger in men (n = 321,236; 57 reports; HR = 1.37, 95%CI 1.27-1.48) than in women (n = 226,886; 56 reports; HR = 1.21, 95%CI 1.12-1.30; p = .017). A subset of the studies focusing on women showed significant associations between anger/hostility, depression, and distress with MACE. For men, statistically significant associations were found for anxiety, depression, and distress with MACE. CONCLUSIONS: Psychological factors are associated with MACE in samples with IHD in both women and men, with a small, but significant higher risk for men. Because of the limited number of studies on other psychological factors than depression and anxiety and the current major focus on MACE reflecting lesions in the major coronary arteries which is more typical in men than women, more research is needed to better identify sex and gender differences in IHD.

Increased Vascular Pathology in Older Veterans With a Purple Heart Commendation or Chronic Post-Traumatic Stress Disorder.

The goal of this retrospective cohort study was to determine whether stressors related to military service, determined by a diagnosis of chronic post-traumatic stress disorder (cPTSD) or receiving a Purple Heart (PH), are associated with an increased risk of vascular risk factors and disease, which are of great concern for veterans, who constitute a significant portion of the aging US population. The Veterans Integrated Service Network (VISN) 16 administrative database was searched for individuals 65 years or older between October 1, 1997 to September 30, 1999 who either received a PH but did not have cPTSD (PH+/cPTSD-; n = 1499), had cPTSD without a PH (PH-/cPTSD+; n = 3593), had neither (PH-/cPTSD-; n = 5010), or had both (PH+/cPTSD+; n = 153). In comparison to the control group (PH-/cPTSD-), the PH+/cPTSD- group had increased odds ratios for incidence and prevalence of diabetes mellitus, hypertension, and hyperlipidemia. The PH-/cPTSD+ group had increased odds ratios for prevalence of diabetes mellitus and for the incidence and prevalence of hyperlipidemia. The PH-/cPTSD+ and PH+/cPTSD- groups were associated with ischemic heart disease and cerebrovascular disease, but not independently of the other risk factors. The PH+/cPTSD+ group was associated only with an increase in the incidence and prevalence of hyperlipidemia, though this group's much smaller sample size may limit the reliability of this finding. We conclude that certain physical and psychological stressors related to military service are associated with a greater incidence of several vascular risk factors in veterans aged 65 years or older, which in turn are associated with greater rates of ischemic heart disease and cerebrovascular disease.
