Depression In Coronary Artery Disease Research Articles

Prevalence of depression in postmyocardial infarction patients in a tertiary care center in Riyadh.

The coexistence of coronary artery disease (CAD) and depression is a growing concern, as both conditions lead to disability. Although depression is more prevalent in CAD patients than in the general population and has been associated with adverse cardiac outcomes, the underlying mechanisms linking depression and CAD are not yet fully understood. This study aims to assess the prevalence of depression in postmyocardial infarction (MI) patients as baseline data in Saudi Arabia. A cross-sectional study was conducted at King Saud Medical City, Riyadh. The study population included male and female patients who had survived MI from January 2022 to June 2022. A sample size of 323 patients was initially planned, but only 249 patients could be included on account of exclusions. The patients underwent screening for depression using Patient Health Questionnaire-2 (PHQ-2), and those who were positive on screening were further assessed using the PHQ-9 according to DSM-5 criteria. Sociodemographic data, comorbidities, and previous cardiac interventions were collected from medical records. The mean age of the study participants was 57.15 years, and majority (76.6%) were males. The prevalence of previously diagnosed depression was 9.2%, and 5.2% of patients reported using antidepressant medication. According to the PHQ-9 scores, 33.33% had depression, 9% had moderate depression, and 2.4% had severe depression. There were significant associations between the severity of depression and previous CAD (P < 0.05), previous coronary artery bypass graft surgery (P < 0.05), and heart failure (P < 0.05). This study reveals a high prevalence of depression in post-MI patients at King Saud Medical City. The findings highlight the need for comprehensive management of depression in this population to improve outcomes. Further research into the underlying mechanisms linking depression and CAD to develop effective interventions is required.

CORONARY ARTERY DISEASE AND DEPRESSION: A MISSING PILLAR IN MANAGEMENT

Patients with coronary artery disease have multiple co-morbids that include dyslipidemia, hypertension, diabetes mellitus, smoking and physical inactivity. It has been seen that depression is another issue in these patients that need close attention. Studies have shown that it affects between 20% and 40% in patients with coronary artery disease (CAD) and have a higher prevalence than in general population.1 One of the study done by SS Bokhari et al.2 has shown a point prevalence of depression in CAD as 37% (31.3% males and 53.8% females).&#x0D; Numerous studies have shown that patients with CAD and depression have poor health outcomes.3 Depression in different aspects in Pakistani population after myocardial infarction,4 after PCI5 and in in-hospital patients with CAD6 were evaluated and found to have significant mental illness which co-relates with the results of other international studies.&#x0D; Keeping all the research studies American Heart Association wrote a scientific statement and endorsed depression as a risk factor for cardiac morbidity and mortality.7 Importance of depression screening as a part of myocardial infarction protocol for caring patients with Ischemic Heart Disease was seen in TRIUMPH trial (Translational Research Investigating Underlying Disparities in Acute Myocordial Infarction Patients Health Status)8 ENRICHD Trial (Enhancing Recovery in Coronary Heart Disease)9 use of citalopram or serlatine plus as clinical management was used for depressive symptoms with CAD in CREATE Trial (Canadian Cardiac Randomized Evaluation of Antidepressant and Psychotherapy Efficacy).10&#x0D; In Pakistan where prevalent of CAD is high i.e. one in 4 middle age adults,11 managing such patients are numerous that includes revascularization (Surgical and Interventional), drugs and treatment of modifiable and nonmodifiable risk factors. Despite all these efforts it’s a need of time to focus on diagnosing depression in CAD to improve outcomes. Depression screening should be conducted to identify these important risk factors and treated with drugs in reducing morbidity and mortality.&#x0D; References&#x0D; &#x0D; Lett HS, Blumenthal JA, Babyak MA, Sherwood A, Strauman T, Robins C, et al.

Cortisol Awakening Reaction and Anxiety in Depressed Coronary Artery Disease Patients.

Disturbances of HPA axis functioning as represented by cortisol awakening reaction (CAR) belong to the mediating pathways linking psychosocial distress and cardiovascular risk. Both depression and anxiety have been confirmed as independent risk factors for coronary artery disease (CAD). However, data on anxiety and cortisol output in CAD patients are scarce. Based on previous data, we hypothesized that anxiety would be associated with higher cortisol output and a more pronounced morning increase in moderately depressed CAD patients. 77 patients (60 y, 79% male) underwent saliva sampling (+0, +30, +45, +60 min after awakening, midday and late-night sample). Anxiety was measured using the Hospital Anxiety and Depression Scale (HADS) and patients were grouped into anxious versus non anxious subjects based upon the recommended score (≥11). A repeated measures ANOVA yielded a significant time and quadratic time effect referring to the typical CAR. Anxious patients showed a significantly steeper 30 min increase, higher AUCi, lower waking and late-night cortisol levels. The steeper cortisol increase in the anxious group is in line with previous data and may be interpreted as a biological substrate of affect regulation. The lower basal and late-night levels coupled with greater AUCi mirror a more dynamic reactivity pattern compared to depressed subjects without anxiety.

Depression, anxiety, and vital exhaustion are associated with pro-coagulant markers in depressed patients with coronary artery disease – A cross sectional and prospective secondary analysis of the SPIRR-CAD trial

IntroductionA hyper-coagulant state is a biological mechanism that triggers cardiac events in patients with coronary artery disease (CAD). Depressive symptoms and anxiety predict an unfavourable course of CAD. The SPIRR-CAD-RCT examined the effects of a psychological intervention and provided the opportunity to explore cross-sectional associations between indices of psychological strain and coagulation parameters, as well as prospective changes in depression scores and coagulation parameters. MethodsIn this secondary analysis, we investigated 253 CAD patients (194 male; age m 58.9, SD 8.3 yrs.) with mild to moderate depression (≥8 on the HADS-D) at baseline and at follow-up 18 months later: TF, fibrinogen, D-dimer, VWF, FVII and PAI-1 and the course of depression (HAM-D), vital exhaustion (VE) and anxiety scores (HADS-A) were examined by ANOVA in the total and younger age groups (≤ 60). ResultsHAM-D at baseline was correlated with TF (corr. R2 = 0.27; F = 9.31, p = 0.001). HADS anxiety was associated with fibrinogen (corr. R2.20; F = 7.27, p = 0.001). There was no detectable therapeutic effect on coagulation. Fibrinogen and VWF decreased within 18 months (time effect; p = 0.02; p = 0.04), as did HADS-D in both treatment groups (p < 0.001). Fibrinogen decreased more in patients ≤60 years with high VE compared to low VE (interaction time x group, p = 0.01). ConclusionsThis is the first study to show an association between TF and depression. Coagulation parameters as potential mediators of CAD progression correlated cross-sectionally with depression and anxiety and prospectively with VE. Further studies should replicate these correlations in depressed and non-depressed CAD patients.ISRCTN: 76240576; clinicaltrials.gov

Psychiatric and Psychological Interventions for Depression in Patients With Heart Disease: A Scoping Review.

Depression in patients with cardiovascular disease is independently associated with progression of heart disease, major adverse cardiac events, and mortality. A wide variety of depression treatment strategies have been studied in randomized controlled trials as the field works to identify optimal depression treatments in this population. A contemporary scoping review of the literature can help to consolidate and synthesize the growing and disparate literature on depression treatment trials in people with cardiovascular disease. We conducted a scoping review utilizing a systematic search of the literature via 4 databases (PubMed, PsycINFO, EMBASE, and Google Scholar) from database inception to March 2020. We identified 42 relevant randomized controlled trials of depression treatment interventions in patients with cardiac disease (n=9181 patients with coronary artery disease, n=1981 patients with heart failure). Selective serotonin reuptake inhibitors appear to be safe in patients with cardiac disease and to have beneficial effects on depression (and some suggestion of cardiac benefit) in patients with coronary artery disease, with less evidence of their efficacy in heart failure. In contrast, psychotherapy appears to be effective for depression in coronary artery disease and heart failure, but with less evidence of cardiac benefit. Newer multimodal depression care management approaches that utilize flexible approaches to patients' care have been less studied but appear promising across cardiac patient groups. Selective serotonin reuptake inhibitors may be preferred in the treatment of patients with coronary artery disease, psychotherapy may be preferred in heart failure, and more flexible depression care management approaches have shown promise by potentially using both approaches based on patient needs.

The Relationship between Depression Symptoms and Severity of Coronary Artery Disease in Patients Undergoing Angiography.

Objective: Cardiovascular diseases are the main cause of mortality worldwide. Depression is one of the effective factors in the incidence of cardiovascular diseases like coronary artery stenosis. This study aimed to investigate the relationship between depression symptoms and severity of coronary artery disease (CAD) in patients scheduled for angiography. Method : This prospective, cross sectional research was conducted on as many as 401 patients scheduled to undergo angiography at Dr. Heshmat heart hospital as the referral center in the north of Iran in 2016. Before cardiac catheterization, patients' demographic information (age, gender, level of education, and place of residence) and patients’ medical history (history of diabetes mellitus, hypertension, and family history of cardiac disease) were obtained. Also, Beck Depression Questionnaire 2 (BDI II) was completed by a psychologist before angiography. After collecting the data, SPSS v.21 and statistical tests such as Spearman correlation, and Mann-Whitney U regression were used to analyze the data. Results: After controlling for age, sex, and having history of diabetes mellitus, no relation was found between having depression symptoms and more frequency of vessel involvement (OR = 1.35, 95% CI: 0.92 to 1.98, P =0.130) or higher severity of CAD (OR = 1.47, 95% CI: 0.95 to 2.28, P = 0.087). The results were similar for the relation between severity of depression symptoms and CAD extent or CAD severity. Conclusion: The results of this study showed that in patients undergoing angiography, depression symptoms were not related to CAD severity and number of involved vessels. Depression was associated with angina, independently of CAD severity. Our study found no significant correlation between CAD severity and severity of depression. The reason may be that measuring depression at a single time point cannot accurately reveal the impact of this problem on the trend of atherosclerosis over time.

The impact of SSRIs on mortality and cardiovascular events in patients with coronary artery disease and depression: systematic review and meta-analysis.

Depression is common in patients after acute coronary syndromes (ACS) and with stable coronary artery disease (CAD) and has been associated with increased mortality and morbidity. However, it is unclear whether selective serotonin receptor inhibitors (SSRIs) reduce mortality or cardiac events in patients with CAD and depression. We conducted a systematic review and meta-analysis to assess the effects of SSRIs on cardiovascular events in depressed CAD patients. The CENTRAL, MEDLINE, and PsycINFO databases were searched (April 2020) for randomized controlled trials (RCTs) and extended follow-up analyses of RCTs that compared SSRIs with placebo or no intervention in patients with CAD and depression. The primary outcomes were all-cause mortality, cardiovascular mortality, and myocardial infarction incidence. The results were calculated through random-effect meta-analyses and reported in terms of risk ratio (RR) with 95% confidence intervals (CI). We retrieved 8 RCTs (2 of which with extended follow-up analyses), comprising a total of 1148 patients. 7 studies only included post-ACS patients. SSRIs were associated with a significantly lower risk of myocardial infarction in patients with CAD and depression (RR 0.54, 95% CI 0.34-0.86), and in post-ACS patients with depression (RR 0.56, 95% CI 0.35-0.90). We found no statistically significant difference in all-cause mortality, cardiovascular mortality, hospitalizations, angina, congestive heart failure, or stroke incidence. The use of SSRIs in post-ACS patients with depression was associated with a 44% relative risk reduction of myocardial infarction. No difference in mortality was found. Given that the quality of the evidence was low, further research is warranted.

4581 Autonomic Dysfunction as a Marker of Depression and Coronary Artery Disease

OBJECTIVES/GOALS: Dysfunction of the autonomic nervous system (ANS) may be important in both depression and coronary artery disease (CAD). A novel heart rate variability (HRV) metric, Dyx, may be a be a potentially useful tool to study ANS dysfunction in these diseases. We propose that ANS dysfunction, measured by decreased Dyx, will associate with both depression and obstructive CAD. METHODS/STUDY POPULATION: We included participants undergoing coronary angiography for suspected CAD. Depressive symptoms were assessed with the Patient Health Questionnaire-9 (PHQ-9). HRV data were collected continuously on participants before catheterization using a new ECG patch (VivaLNK). We assessed HRV by Dyx (primary) and high and low frequency power, multiscale entropy, and deceleration capacity. Two-sample t-tests and logistic regressions (with adjustment for age and sex) were used to study the difference in HRV (before cardiac catheterization) between those with high versus low depressive burden (PHQ-9 ≥ 10), and in those with versus without obstructive CAD (&gt;70% stenosis). RESULTS/ANTICIPATED RESULTS: We assessed 30 individuals with mean (SD) age 62.4 (13.2); 7.1% were female and 15.4% were black. Mean Dyx in high depressive symptoms (N = 21, 70%) was 1.8 (0.2) and in none-low depressive symptoms (N = 7, 23%) was 2.2 (0.2). Differences were also observed for high frequency (HF) (4.4 (1.1) vs. 6.0 (1.4)) and deceleration capacity (−4.2 (2.1) vs. −10.7 (8.5)). Mean Dyx in obstructive CAD (N = 17, 57%) and non-obstructive CAD (N = 10, 33%) was 1.7 (0.6) and 2.6 (1.2) respectively. Differences were seen with sample entropy (1.2 (0.2) vs. 1.5 (0.2)). Every 1 unit of log(HF) had an odds ratio = 0.14 (95% CI 0.06 – 0.36) for depression. DISCUSSION/SIGNIFICANCE OF IMPACT: ANS dysfunction, measured by HRV, associates with both depression and obstructive CAD. Autonomic ECG markers may play an important role in assessing brain-heart pathology, and may be useful to study the interaction between depression and CAD.

Length Polymorphisms in the Angiotensin I-Converting Enzyme Gene and the Serotonin-Transporter-Linked Polymorphic Region Constitute a Risk Haplotype for Depression in Patients with Coronary Artery Disease

Genetic variations affecting the course of depressive symptoms in patients with coronary artery disease (CAD) have not yet been well studied. Therefore, we set out to investigate whether distinct haplotypes of the two insertion/deletion polymorphisms in the serotonin-transporter-linked polymorphic region (5-HTTLPR) and the angiotensin I-converting enzyme (ACE) gene located on chromosome 17 can be identified as risk factors for trajectories of depression. Clinical and genotyping data were derived from 507 depressed CAD patients participating in the randomized, controlled, multicenter Stepwise Psychotherapy Intervention for Reducing Risk in Coronary Artery Disease (SPIRR-CAD) trial, of whom the majority had an acute cardiac event before study inclusion. Depression scores on the Hospital Anxiety and Depression Scale (HADS) were assessed at baseline and at five follow-up time points up to 2 years after study entrance. At baseline, depression scores did not significantly differ between patients carrying the risk haplotype ACE D/D, 5-HTTLPR I/I (n = 46) and the non-risk haplotypes (n = 461, 10.9 ± 2.7 versus 10.4 ± 2.5, p = 0.254). HADS-depression scores declined from study inclusion during the first year irrespective of the genotype. At each follow-up time point, HADS-depression scores were significantly higher in ACE D/D, 5-HTTLPR I/I carriers than in their counterparts. Two years after study inclusion, the mean HADS depression score remained 1.8 points higher in patients with the risk haplotype as compared to subjects not carrying this haplotype (9.9 ± 4.2 versus 8.1 ± 4.0, p = 0.009). In summary, the presence of the ACE D/D, 5-HTTLPR I/I haplotype may be a vulnerability factor for comorbid depressive symptoms in CAD patients.

Effects of a mental stress challenge on brain function in coronary artery disease patients with and without depression.

Coronary artery disease (CAD) patients with comorbid depression show an increase in mortality compared to cardiac patients without depression, but the mechanisms mediating this effect remain obscure. One possible explanation for this finding is that depressed patients with CAD exhibit an increased vulnerability to stress. The purpose of this study was to assess the effects of stress and depression on brain function and to explore its relationship with myocardial ischemia in CAD patients. Patients with CAD and depression (N = 13) and CAD without depression (N = 15) underwent imaging of the brain with positron emission tomography and [O-15] water and imaging of the heart with single photon emission computed tomography (SPECT) and [Tc-99m] sestamibi under mental stress task and control conditions. CAD patients with depression compared to nondepressed showed decreased function with mental stress in the rostral anterior cingulate, the hippocampus, parts of the dorsolateral temporal and parietal cortex, the cerebellum, and the uncus, with increased blood flow in the parahippocampus, visual association cortex, and posterior cingulate. Depressed CAD patients who became ischemic during a mental stress task had relative decreases in the caudal and posterior cingulate, orbitofrontal cortex, and cerebellum, and increased activation in the parietal cortex and precuneus/visual association cortex compared to nonischemic depressed CAD patients. These findings are consistent with dysfunction in a network of brain regions involved in the stress response in patients with comorbid CAD and depression that has direct and indirect links to the heart, suggesting a pathway by which stress and depression could lead to increased risk of heart disease related morbidity and mortality.

Brain mechanisms of stress and depression in coronary artery disease

IntroductionMajor depression is associated with an increased risk for and mortality from coronary artery disease (CAD), however the mechanisms by which this occurs are not clear. Depression, which is linked to stress, is associated with changes in brain areas involved in memory and the stress response, and it is likely that these regions play an important role in this increased risk. This study assessed the effects of stress on brain and cardiac function in patients with CAD with and without depression. MethodsCAD patients with (N = 17) and without (N = 21) major depression based on the Structured Clinical Interview for DSM-IV (DSM-IV) and/or a Hamilton Depression Scale score of nine or greater underwent imaging of the brain with high resolution positron emission tomography (HR-PET) and [O-15] water and imaging of the heart with single photon emission tomography (SPECT) and [Tc-99 m] sestamibi during mental stress (mental arithmetic) and control conditions. ResultsPatients with CAD and major depression showed increased parietal cortex activation and a relative failure of medial prefrontal/anterior cingulate activation during mental stress compared to CAD patients without depression. Depressed CAD patients with stress-induced myocardial ischemia, however, when compared to depressed CAD patients without showed increased activation in rostral portions of the anterior cingulate. ConclusionsThese findings are consistent with a role for brain areas implicated in stress and depression in the mechanism of increased risk for CAD morbidity and mortality in CAD patients with the diagnosis of major depression.

Longitudinal associations between 4-hydroxynonenal and depression in coronary artery disease patients

Depressive symptoms in patients with coronary artery disease (CAD) attenuate the cardiovascular benefits of cardiac rehabilitation (CR). Given that oxidative stress may be an important mechanism underlying depression, this study aimed to understand the longitudinal relationship between lipid peroxidation markers and depression in CAD. Serum levels of early (lipid hydroperoxides, LPH) and late (4‑hydroxy‑2-nonenal, 4-HNE; 8-isoprotane, 8-ISO) lipid peroxidation markers were measured in 120 CAD patients undergoing CR. The Structured Clinical Interview for DSM Axis I Disorders – Depression Module (SCID) was used to diagnose depression at baseline and the Center for Epidemiological Studies Depression Scale (CES-D) was used to measure depressive symptom severity. Multivariate mixed models compared the trajectories of serum LPH, 4-HNE, and 8-ISO between depressed and non-depressed CAD patients undergoing 6 months of CR. Similar models evaluated the associations between serum LPH, 4-HNE, and 8-ISO and CES-D score over the course of CR. Serum 4-HNE decreased less in CAD patients with depression compared to those without. In addition, a decrease in 4-HNE concentrations was significantly associated with a decrease in CES-D scores over 6 months. These findings suggest that 4-HNE may be an important marker of depressive symptoms in CAD and may be involved in its progression.

Associations of NT-proBNP and parameters of mental health in depressed coronary artery disease patients

Natriuretic peptides (NP) are involved in the regulation of blood pressure and blood volume, and are elevated in patients with coronary artery disease (CAD). They are used as markers for illness severity, but their role in mental health is not well understood. Recently, A-type NP (ANP) has been associated with reduced anxiety in studies on cardiac patients; however, this study is the first to assess this effect for B-type NP (BNP) and for further dimensions of well-being and mental health. Depression, anxiety, and distress are more common in CAD patients than in the general population and are most likely not only influenced by psychological adaptation but also by neurobiological processes. We used baseline N-terminal proBNP (NT-proBNP) samples and psychometric assessments of 529 at least mildly depressed (Hospital Anxiety and Depression Scale, depression score ≥ 8) CAD patients from the multicenter Stepwise Psychotherapy Intervention for Reducing Risk in Coronary Artery Disease (SPIRR-CAD) trial. Psychosocial status was assessed using standardized self-rating questionnaires on anxiety, depression, coping with illness, vital exhaustion, type D personality, and quality of life. Separate linear regression models for each psychometric scale revealed significant negative correlations of NT-proBNP with anxiety, depression, vital exhaustion, depressive coping, and negative affectivity. Moreover, patients with higher levels of NT-proBNP experienced less bodily pain and had a better self-rated mental health, despite worse physical functioning. Linear regression adjusted for age, sex, and physical functioning (Short Form Health Survey [SF-36]) revealed NT-proBNP to be a significant predictor for all tested measures of the patients’ psychosocial status. These results indicate that NT-proBNP is not only positively associated with greater disease severity in mildly to moderately depressed CAD patients but also with better psychosocial status and mental well-being. Possible mechanisms of this effect are discussed.

The relationship between attachment orientations and the course of depression in coronary artery disease patients: A secondary analysis of the SPIRR-CAD trial

ObjectiveThe relationship between attachment orientations and the recovery from depressive symptoms in patients diagnosed with coronary artery disease (CAD) with and without a psychotherapeutic intervention was examined in this study. MethodsIn a multicenter trial of 570 depressed CAD patients (SPIRR-CAD), assigned to usual care plus either a stepwise psychotherapy intervention or one information session, 522 patients provided attachment data at baseline. Attachment was measured with the Relationship Scales Questionnaire (RSQ), yielding four attachment orientations. The primary outcome was change in Hospital Anxiety and Depression Scale depression (HADS-D) scores from baseline to follow-up at 18 months. Secondary outcomes were HADS-D scores at 1, 6, 12, and 24 months. ResultsIndependent of treatment assignment, attachment was related to change in depression at 18 months (p < 0.01) with secure attachment resulting in a significant reduction (−2.72, SE = 0.27) in depression compared to dismissive-avoidant (−1.51, SE = 0.35, p = 0.040) and fearful-avoidant (−0.65, SE = 0.61, p = 0.012) attachment. Patients with anxious-preoccupied attachment showed changes similar to secure attachment (−2.01, SE = 0.47). An explorative subgroup analysis across all assessment time points revealed patients with a dismissive-avoidant attachment benefitted from psychotherapy (average mean difference = 0.93, SE = 0.47, p = 0.048). ConclusionAttachment played an important role for improvement in depressive symptoms. Only dismissive-avoidant patients seemed to benefit from the intervention. The lack of improvement in fearful-avoidant patients shows a need for specific interventions for this group.Trial Registration: www.clinicaltrials.govNCT00705965; www.isrctn.com ISRCTN76240576.

Plasma sphingolipids and depressive symptoms in coronary artery disease.

BackgroundDepression is highly prevalent in individuals with coronary artery disease (CAD) and increases the risk of future cardiac events and mortality. Sphingolipids have been implicated in the pathophysiology of both CAD and depression. This study assessed the association between plasma sphingolipid concentrations and depressive symptoms in CAD subjects.MethodsDepressive symptoms were measured using the depression subscale of the self‐reported Hospital Anxiety and Depression Scale (HADS). Sphingolipid concentrations were measured from fasting plasma samples using high‐performance liquid chromatography‐coupled electrospray ionization tandem mass spectrometry (LC/MS/MS). Linear regression models were used to assess associations between log‐transformed concentrations of plasma sphingolipids and depressive symptoms.ResultsA total of 111 CAD patients (mean (SD) age = 63.6 ± 6.4, 84.7% male) were included. In linear regression analyses, higher plasma concentrations of ceramides C16:0 (β = 0.204, p = .026) and C18:0 (β = 0.209, p = .023) and sphingomyelin SM18:1 (β = 0.210, p = .024) were significantly associated with higher HADS depression subscale score after adjusting for covariates.ConclusionSphingolipids, in particular the ceramide species C16:0 and C18:0 and the sphingomyelin species SM18:1, may be implicated in the pathophysiology of depression in CAD. The association between plasma sphingolipid concentrations and depression should be further examined in CAD patients and in other populations.

A Stepwise Psychotherapy Intervention for Reducing Risk in Coronary Artery Disease (SPIRR-CAD): Results of an Observer-Blinded, Multicenter, Randomized Trial in Depressed Patients With Coronary Artery Disease.

Depression predicts adverse prognosis in patients with coronary artery disease (CAD), but previous treatment trials yielded mixed results. We tested the hypothesis that stepwise psychotherapy improves depressive symptoms more than simple information. In a multicenter trial, we randomized 570 CAD patients scoring higher than 7 on the Hospital Anxiety and Depression Scale-depression subscale to usual care plus either one information session (UC-IS) or stepwise psychotherapy (UC-PT). UC-PT patients received three individual psychotherapy sessions. Those still depressed were offered group psychotherapy (25 sessions). The primary outcome was changed in the Hospital Anxiety and Depression Scale-depression scores from baseline to 18 months. Preplanned subgroup analyses examined whether treatment responses differed by patients' sex and personality factors (Type D). The mean (standard deviation) depression scores declined from 10.4 (2.5) to 8.7 (4.1) at 18 months in UC-PT and from 10.4 (2.5) to 8.9 (3.9) in UC-IS (both p < .001). There was no significant group difference in change of depressive symptoms (group-by-time effect, p = .90). Preplanned subgroup analyses revealed no differences in treatment effects between men versus women (ptreatment-by-sex interaction = .799) but a significant treatment-by-Type D interaction on change in depressive symptoms (p = .026) with a trend for stronger improvement with UC-PT than UC-IS in Type D patients (n = 341, p = .057) and no such difference in improvement in patients without Type D (n = 227, p = .54). Stepwise psychotherapy failed to improve depressive symptoms in CAD patients more than UC-IS. The intervention might be beneficial for depressed CAD patients with Type D personality. However, this finding requires further study. www.clinicaltrials.gov NCT00705965; www.isrctn.com ISRCTN76240576.

Unique Aspects of Coronary Artery Disease in Indian Women.

Epidemiologic and clinical research suggests important gender-related differences in the prevalence, presentation, associated conventional and non-conventional risk factors, management and outcomes of coronary heart disease (CHD) patients. Adequate data is not available for Indian population where prevalence of CHD and depression is high. We conducted an observational, single-center, study from January 2010 to December 2011 on 10450 consecutive patients visiting a tertiary care center, Ahmedabad, Gujarat, India who presented with complaints related to CHD. Of these, 6867 patients had coronary artery disease (CAD) as confirmed by angiographic investigation; 5678 were males, and 1189 were females with similar mean age. As compared to males, females had higher prevalence of hypertension, diabetes and obesity while males had higher prevalence of smoking. Invasive treatment options like Coronary Artery Bypass Grafting (p < 0.001) and Percutaneous Coronary Intervention (p = 0.001) were used less often to treat females, and medical therapy (p < 0.001) was the preferred treatment option irrespective of the contributing risk factors/extent of CAD. Depression was observed in 39.8% of acute coronary syndrome patients (n = 1648) as assessed by MARDS scale. It was higher in female patients and in low socioeconomic strata (p < 0.001).At 12 and 36 months, rates of revascularization (p < 0.001) and mortality (p < 0.005) were higher with poor quality of life (QoL) (P < 0.001) in depressed CAD patients. In India, women appear to have a higher prevalence of hypertension, diabetes, obesity, and family history of CHD. Yet women get invasive treatments less often than men. Depression is also more common in women and is associated with poor QoL and early mortality than men.

Serum inflammatory cytokines and depression in coronary artery disease.

Background:Severe depression may be accompanied by immune dysregulation and is also associated with increased risk of coronary artery disease (CAD).Objectives:We investigated serum levels of 10 cytokines and their relationship with depression in patients with cardiovascular diseases as well as healthy subjects in northeast of Iran.Patients and Methods:The study was carried out on 462 subjects (120 healthy subjects and 342 candidates undergoing angiography). The healthy subjects were referred for routine annual checkups or pre-employment examinations; they did not have clinically evident CAD. A questionnaire was used to obtain demographic data and the Beck depression inventory (BDI) was applied to assess depression. The Evidence Investigator® platform was used for cytokines assays for IL-1α, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, TNF-α, MCP-1 and IFN-γ, using sandwich chemiluminescent method. The statistical analysis was performed using SPSS version 11.5.Results:The mean age was 53.3 ± 11.5, 54.8 ± 11.3, and 59.5 ± 11.3 in healthy, angiography (-), and angiography (+) subjects, respectively (P < 0.05). There were significant differences in serum levels of IL-4, IL-6, IL-10, and MCP-1 cytokines, comparing subjects with CAD and healthy persons (P < 0.05). When all subjects were divided to with and without depression regardless of their cardiovascular status, there was a significant difference in serum levels of IL-8 and IL-6 between the groups (P < 0.05). When the subgroup with features of CAD was selected and divided to those with and without depression, there was also a significant difference in serum levels of IL-8 and TNF-α (P < 0.05).Conclusions:The positive interaction between depression and CAD was probably mediated by inflammatory mechanisms.

Relation of Major Depression to Survival After Coronary Artery Bypass Grafting

The primary aim was to study the association between preoperative depression and long-term survival after coronary artery bypass grafting (CABG). Our secondary objective was to analyze the association between depression and cardiovascular events or all-cause mortality. In a nationwide, population-based, cohort study, all patients who underwent CABG in Sweden from 1997 to 2008 were included from the Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies registry. Individual-level data were cross-linked from other national Swedish registers. Depression status and outcomes were obtained from the National Patient Register. The study population was 56,064 patients who underwent primary, isolated, nonemergent CABG. We identified 324 patients (0.6%) with depression before CABG. During a mean follow-up of 7.5years, 114 patients (35%) with depression died, compared with 13,767 patients (25%) in the control group. Depression was significantly associated with increased mortality and the combined end point of death or rehospitalization for myocardial infarction, heart failure, or stroke (multivariate-adjusted hazard ratios [95% confidence intervals] 1.65 [1.37 to 1.99] and 1.61 [1.38 to 1.89], respectively). In conclusion, we found a strong and significant association between depression and long-term survival in patients with established ischemic heart disease who underwent CABG. Depression was also associated with an increased risk for a combination of death or rehospitalization for heart failure, myocardial infarction, or stroke.

Depression in coronary artery disease.

Depression is one of the Common psychological disorders. From the cognitive point of view, the unhealthy attitudes increase the severity of the depression. The aim of this study was to investigate depression and unhealthy attitudes in coronary patients hospitalized at Tabriz Shahid Madani Heart Center. One hundred twenty eight hospitalized patients having myocardial Infarctions were studied regarding unhealthy attitudes, severity of depression and demographic data. The study showed a significant relation between unhealthy attitudes, BDI (Beck Depression Inventory) and severe depression. Moreover, a significant relation existed between gender and depression (P=0.0001). In addition, the level of education increased the intensity of unhealthy attitudes (P=0.0001). Several researches in both outside and inside Iran support the idea. Based on present study and more other investigations, it can be suggested to provide the necessary elements and parameters such as antidepressant medication, psychologists, complementary treatment for coping with negative mood and its unwanted consequences.
