Background The occurrence and development of acute coronary syndrome (ACS) are closely associated with inflammatory responses, but the relationship between dietary inflammatory potential and severity of coronary artery disease of ACS patients is currently unknown. Objective To investigate the relationship between dietary inflammatory potential evaluated by dietary inflammation index (DII) and severity of coronary artery disease in ACS patients. Methods Convenient sampling method was used to select 309 patients diagnosed as ACS for the first time by coronary arteriography in the Department of Cardiology, the Second Affiliated Hospital of Harbin Medical University from April 2022 to March 2023, and they were divided into DII-1 group (from -8.35 to -4.56), DII-2 group (from -4.55 to -0.77), DII-3 group (from -0.76 to 3.02) and DII-4 group (from 3.03 to 6.81) according to the quartile of DII, into Q1 group (4-32 scores), Q2 group (34-52 scores), Q3 group (54-84 scores) and Q4 group (86-192 scores) according to the quartile of Gensini score. Demographic and clinical features, overall DII, and DII of nutrient were compared in ACS patients with different severity of coronary artery stenosis, multivariate Logistic regression analysis was used to analyze the relation of DII with the severity of coronary artery stenosis. Results There was significant difference in educational level, LDL-C, LP-a, overall DII, DII of total fat, saturated fatty acids, vitamin E, carotene in ACS patients with different severity of coronary artery stenosis, respectively (P≤0.05). After the correction of confounders of educational level, LDL-C and LP-a, the multivariate Logistic regression analysis showed that, DII-4 group was the influencing factor of Q2 group (OR=15.389, 95%CI=1.595-148.432), Q3 group (OR=15.102, 95%CI=1.620-140.788) and Q4 group (OR=17.319, 95%CI=1.901-157.807), respectively (P

We aimed to explore the association between stressful life events and coronary plaque vulnerability, and examine the moderating effects of psychological distress and physiological indices. A total of 311 patients with acute coronary syndrome (ACS) completed Life Events Scale, Zung Self-Rating Depression and Anxiety Scales. Plaque vulnerability was assessed by in vivo optical coherence tomography (OCT). The regression analysis showed that that stressful life events were independent predictors of plaque vulnerability including lipid-rich plaque (OR = 1.018, 95% CI = 1.005, 1.031, p = 0.005), thin-cap fibroatheroma (TCFA) (OR = 1.038, 95% CI = 1.025, 1.051, p < 0.001), rupture (OR = 1.025, 95% CI = 1.013, 1.037, p < 0.001) and thrombus (OR = 1.030, 95% CI = 1.012, 1.048, p = 0.001). The moderated mediation model revealed that there were significant indirect effects of stressful life events on TCFA through total cholesterol, and the path between stressful life events and TCFA can be moderated by depression. Stressful life events increase the risk of vulnerable plaque in ACS patients. The relationship could be moderated by depression and mediated by physiological indices. [ABSTRACT FROM AUTHOR]

Personality traits are associated with major adverse coronary events (MACE) in patients with coronary artery disease (CAD). However, the link between personality traits and intravascular morphology in CAD patients is poorly understood. This study investigated the relationship between personality traits, specifically Type A behavior pattern and Type D personality, and plaque vulnerability. After adjustment for demographic and clinical factors, multivariable regression analysis showed no association between Type A and optical coherence tomography indices. However, Type D personality was independently associated with lipid plaque, thin cap fibroatheroma (TCFA), and fibrous cap thickness. More specifically, negative affectivity of Type D was related to lipid plaque, TCFA and fibrous cap thickness, and social inhibition was associated with plaque rupture. Our results show that Type D personality was associated with plaque vulnerability, independent of clinical factors. Measurement of negative affectivity and social inhibition will increase our understanding of the progressive phase of the plaque vulnerability, which can contribute to the early identification of high risk patients and reduce the incidence of MACE.

Background: Type D personality and depression are the independent psychological risk factors for adverse outcomes in cardiovascular patients. The aim of this study was to examine the combined effect of Type D personality and depression on clinical outcomes in patients suffering from acute myocardial infarction (AMI)., Methods: This prospective cohort study included 3568 patients diagnosed with AMI between February 2017 and September 2018. Type D personality and depression were assessed at baseline, while the major adverse cardiac event (MACE) rate (cardiac death, recurrent non-fatal myocardial infarction, revascularization, and stroke) and in-stent restenosis (ISR) rate were analyzed after a 2-year follow-up period., Results: A total of 437 patients developed MACEs and 185 had ISR during the follow-up period. The Type D (+) depression (+) and Type D (+) depression (-) groups had a higher risk of MACE [95% confidence interval (CI) 1.74-6.07] (95% CI 1.25-2.96) and ISR (95% CI 3.09-8.28) (95% CI 1.85-6.22). Analysis of Type D and depression as continuous variables indicated that the main effect of Type D, depression and their combined effect were significantly associated with MACE and ISR. Moreover, Type D (+) depression (+) and Type D (+) depression (-) emerged as significant risk factors for MACE and ISR in males, while only Type D (+) depression (+) was associated with MACE and ISR in female patients., Conclusions: These findings suggest that patients complicated with depression and Type D personality are at a higher risk of adverse cardiovascular outcomes. Individual assessments of Type D personality and depression, and comprehensive interventions are required.
