Associations of systemic inflammation and social support with suicidal ideation in patients with acute coronary syndrome and stroke. J Affect Disord 2023; 323:101-107. [PMID: 36436762 DOI: 10.1016/j.jad.2022.11.055] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 11/15/2022] [Accepted: 11/20/2022] [Indexed: 11/27/2022]
Abstract
BACKGROUND This study aimed to investigate associations of serum high-sensitivity C-reactive protein (hsCRP) and social support (SS) levels with suicidal ideation (SI), and to evaluate potential modifying effects of SS on the associations between serum hsCRP levels and SI in two longitudinal cohorts with cardio-/cerebrovascular diseases. METHODS 1152 acute coronary syndrome (ACS) and 423 stroke patients were recruited at baseline within 2 weeks of disease onset, and evaluated for: i) serum hsCRP levels; ii) SS by the Social Support Scale and Social Undermining Scale; iii) SI by the "suicidal thoughts" item of the Montgomery-Åsberg Depression Rating Scale; and iv) covariates including socio-demographics, depression, vascular risk factors, and index disease severity. At 12-month follow-up, SI was re-evaluated. Logistic regression models were used to adjust for potential covariates. RESULTS In the ACS cohort, higher serum hsCRP and lower SS levels were significantly associated with SI at baseline; and only lower SS levels were significantly associated with SI at follow-up. In the stroke cohort, lower SS levels were significantly associated with SI at baseline; but no other association was found. Associations of serum hsCRP levels with SI at both baseline and follow-up were only significant at higher SS levels with significant interaction terms in both cohorts. LIMITATIONS This study evaluated SI, but not suicide attempts or death; it also used a single-center design. CONCLUSIONS By considering SS evaluations with routine serum hsCRP levels in cardio-/cerebrovascular disease, clinical prediction of SI both at acute and chronic phases of the diseases might be improved.

Interaction effects of diabetes and brain-derived neurotrophic factor on suicidal ideation in patients with acute coronary syndrome. Sci Rep 2022; 12:6602. [PMID: 35459929 PMCID: PMC9033782 DOI: 10.1038/s41598-022-10557-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Accepted: 04/01/2022] [Indexed: 11/16/2022] Open
Abstract
Acute coronary syndrome (ACS) is related to an increased risk of suicide. Although both diabetes and the brain-derived neurotrophic factor (BDNF) pathway are closely associated with ACS and suicide, the effects of these factors on suicidal behavior in ACS patients have not been assessed. We investigated the individual and interaction effects of diabetes and BDNF-related markers, namely the serum BDNF (sBDNF) level and the BDNF Val66Met polymorphism, on suicidal ideation (SI) in ACS patients. The presence of diabetes was ascertained, and sBDNF levels and the presence of the BDNF Val66Met polymorphism were measured in 969 patients within 2 weeks after an ACS episode. 711 patients were followed up at 1 year after the ACS episode. SI was assessed using the relevant items of the Montgomery–Åsberg Depression Rating Scale at baseline (acute SI) and the 1-year follow-up (chronic SI). Significant individual effects of low sBDNF levels were found on acute SI. The presence of both diabetes and a low sBDNF level or the BDNF Met/Met genotype was associated with acute SI, with multivariate logistic regression analyses revealing significant interaction effects. The highest frequency of chronic SI was seen in diabetic patients with an sBDNF level in the lowest tertile or with the BDNF Met/Met genotype, although the interaction terms were not statistically significant. Our study suggests that the combination of diabetes and BDNF-related markers, such as the sBDNF level and the BDNF Val66Met polymorphism, might provide a useful predictor of acute SI in ACS patients.

Abstract
BACKGROUND To investigate the impacts of depression screening, diagnosis and treatment on major adverse cardiac events (MACEs) in acute coronary syndrome (ACS). METHODS Prospective cohort study including a nested 24-week randomised clinical trial for treating depression was performed with 5-12 years after the index ACS. A total of 1152 patients recently hospitalised with ACS were recruited from 2006 to 2012, and were divided by depression screening and diagnosis at baseline and 24-week treatment allocation into five groups: 651 screening negative (N), 55 screening positive but no depressive disorder (S), 149 depressive disorder randomised to escitalopram (E), 151 depressive disorder randomised to placebo (P) and 146 depressive disorder receiving medical treatment only (M). RESULTS Cumulative MACE incidences over a median 8.4-year follow-up period were 29.6% in N, 43.6% in S, 40.9% in E, 53.6% in P and 59.6% in M. Compared to N, screening positive was associated with higher incidence of MACE [adjusted hazards ratio 2.15 (95% confidence interval 1.63-2.83)]. No differences were found between screening positive with and without a formal depressive disorder diagnosis. Of those screening positive, E was associated with a lower incidence of MACE than P and M. M had the worst outcomes even compared to P, despite significantly milder depressive symptoms at baseline. CONCLUSIONS Routine depression screening in patients with recent ACS and subsequent appropriate treatment of depression could improve long-term cardiac outcomes.

Synergistic effects of depression and NR3C1 methylation on prognosis of acute coronary syndrome. Sci Rep 2020; 10:5519.

Abstract
High levels of methylation in the GR gene (nuclear receptor subfamily 3, group C, member 1; NR3C1) have been associated with depression and cardiovascular risk. This study aimed to investigate whether NR3C1 methylation status was associated with the long-term prognosis of acute coronary syndrome (ACS) considering depression and cardiovascular status at the early phase of ACS. A total of 969 patients with recent ACS were recruited at a tertiary university hospital in Korea. Baseline evaluations were made from 2007 to 2012, including DSM-IV depressive disorder, NR3C1 methylation, and various demographic and clinical characteristics such as cardiovascular risk markers. Over a 5~12 year follow-up after the index ACS, time to major adverse cardiac event (MACE) was investigated using Cox regression models. Higher NR3C1 methylation status was associated with depression and several cardiovascular risk markers at baseline. NR3C1 hypermethylation predicted worse long-term prognosis of ACS only in the presence of depressive disorder with significant synergistic interaction terms and independent of potential confounding factors. Synergistic effects of depressive disorder and NR3C1 hypermethylation on long-term cardiac outcomes in ACS were found. NR3C1 methylation status represents a candidate prognostic biomarker for ACS in combination with a diagnosis of depressive disorder. Further research is needed to ascertain the generalisability of these findings.

Abstract
Background The prognostic role of BDNF val66met polymorphism on long-term cardiac outcomes in acute coronary syndrome (ACS) has been unclear. Environmental factors may modify the association, but these have not been investigated to date. This study aimed to investigate the potential interactive effects of BDNF val66met polymorphism and personality traits, one of the main environmental prognostic factors of ACS, on major adverse cardiac events (MACEs) in patients with ACS. Methods A total of 611 patients with recent ACS were recruited at a university hospital in Korea. Baseline evaluations from 2007 to 2012 assessed BDNF val66met polymorphism and personality using the Big Five Inventory, which yielded two personality clusters (resilient and vulnerable) and five dimensions (extraversion, agreeableness, conscientiousness, neuroticism, and openness). Over a 5~12 year follow-up after the index ACS, times to MACE were investigated using Cox regression models after adjustment for a range of covariates. Results The BDNF val66met polymorphism modified the associations between vulnerable personality type and worse long-term cardiac outcomes in ACS patients with significant interaction terms, in that the associations were statistically significant in the presence met allele. Similar findings were observed for the individual personality dimensions of agreeableness and neuroticism. Conclusions Gene (BDNF val66met polymorphism) x environment (personality traits) interactions on long-term cardiac outcomes were found in ACS.

Modifying effects of depression on the association between BDNF methylation and prognosis of acute coronary syndrome. Brain Behav Immun 2019; 81:422-429.

Abstract
AIMS Brain-derived neurotrophic factor (BDNF) plays important roles in angiogenesis, inflammation, and neuronal plasticity. BDNF methylation has been extensively investigated in depression, but not in cardiac diseases. We asked whether BDNF methylation status is associated with a major adverse cardiac event (MACE), inflammation, and the association with depression comorbidity and its treatment in patients with acute coronary syndrome (ACS). METHODS AND RESULTS A cross-sectional baseline study and nested 24 week double-blind escitalopram placebo-controlled trial (ClinicalTrial.gov identifier NCT00419471) were performed from 2006 to 2012, with 5-12 year follow-up for MACE. Patients with recent ACS (969 total) were divided into four groups according to depression comorbidity at baseline and treatment allocation: 591, absent depression; 127, depression on escitalopram; 128, depression on placebo; 123, depression on care as usual (CAU). BDNF methylation was measured in leucocyte DNA, and multiple demographic and clinical characteristics including interleukin 6 were evaluated as covariates at baseline. The primary outcome, time to first MACE (a composite of all-cause mortality, myocardial infarction and percutaneous coronary intervention), was investigated using Cox regression models after adjustment for covariates. Interleukin 6 level was significantly higher in patients with higher BDNF methylation values. Higher BDNF methylation was associated with increased MACE independent of confounding factors [HR (95% CI) = 1.45 (1.17-1.78)]. This association was significant in patients without depression [HR (95% CI) = 1.39 (1.01-1.90)] and depressive patients on placebo [HR (95% CI) = 1.72 (1.02-3.02)] or CAU [HR (95% CI) = 1.53 (1.01-2.61)], but not in those treated with escitalopram [HR (95% CI) = 1.00 (0.51-1.95)]. CONCLUSION BDNF methylation was significantly associated with prognosis of ACS. Escitalopram may mitigate the deleterious effect of higher BDNF methylation in depressive patients with ACS. Further research is needed to elucidate the mechanistics and to assess the generalisability of these findings.
