急性冠脉综合征患者血液Rho激酶活性分析

探讨 Rho 激酶（ROCK）活性与急性冠脉综合征（ACS）患者冠状动脉狭窄程度及预后的关系。选取2012年6月至2013年3月住院的129例患者,其中急性心肌梗死（AMI）组68例、不稳定型心绞痛（UA）组30例、对照（CON ）组31例。Western Blot 检测血液白细胞中 ROCK 、ROCK1、ROCK2活性,同时根据冠状动脉的狭窄程度及是否发生心血管意外分组再次比较。 AMI 组和 UA 组 ROCK 、ROCK1、ROCK2活性均增高;且 AMI 组高于 UA 组;三支、双支、单支病变组活性依次减低,Gensini 评分≥20分组及发生心血管意外组均高于 Gensini 评分＜20分组及未发生心血管意外组,差异均有统计学意义（P＜0．05）。 ROCK 活性可能对 ACS 患者预后观察、评估有重要意义。     

DS14 is more likely to measure depression rather than a personality disposition in patients with acute coronary syndrome

It has been suggested that Type D Personality is a risk factor for acute coronary syndrome (ACS) and the DS14 has been developed for its assessment. However, some of the items on the DS14 seem to evaluate depressive symptoms rather than personality features. Therefore, the present study aims to verify whether an overlap exists between the constructs of Type D Personality and depression. Three‐hundred‐and‐four consecutive patients who were both presenting their first ACS and had no history of major depression completed the Hospital Anxiety and Depression Scale (HADS) and the DS14 to assess Type D personality at baseline and have been re‐evaluated at 1, 2, 4, 6, 9 and 12‐month follow‐ups. Out of 304 subjects (80.6% males), 40 were diagnosed as depressed. An exploratory factor analysis of HADS and the DS14 in the second month revealed that four out of seven items on the depressive subscale of HADS (HADS‐D) and six out of seven items on the Negative Affectivity (NA) subscale of the DS14 segregated on the same factor. Results were verified by a Partial Confirmatory Factor Analysis performed at the twelfth month when most of the patients achieved complete remission from the depressive episode. Temporal stability was poor for NA and Type D Personality and these construct co‐vary with HADS‐D over time. Our data suggests that NA and depression are overlapping constructs, supporting the idea that the DS14 measures depressed features, rather than a personality disposition.     

The psychosocial predictors of long-term distress in partners of patients with acute coronary syndrome

Objective: Partners of acute coronary syndrome (ACS) patients are at risk of experiencing long-term distress and the purpose of this study was to identify its predictors.

Design: Using an observational design, 80 partners of ACS patients completed validated questionnaires at three time points. The predictor variables, marital satisfaction and optimism were assessed three weeks after patient hospital discharge (T1). The outcomes, depressive symptoms and physical health status (from a quality of life scale) were measured 6 (T2) and 12 (T3) months post-discharge, and scores were combined to indicate the long-term response.

Main outcome measures: Depressive symptoms and physical health status.

Results: Partner depressive symptoms increased and physical health status deteriorated over the months following the patients’ ACS. After controlling for demographics, clinical severity of ACS and T1 levels of the outcome variable, partners’ long-term depressive symptoms were predicted by poor marital satisfaction and low optimism at T1, and poor physical health status was predicted by low T1 optimism.

Conclusion: Psychosocial factors are predictors of long-term distress for ACS partners. Partners in an unhappy marriage or with low optimism after ACS are at an increased risk of depression and low physical health status, and should be the target of additional support.     

Type a behaviour,social contact and coronary death

Abstract

The risk of coronary death associated with Type A behaviour (Framingham definition) and social contact was examined using a retrospective case-control design. Logistic regression analysis of 134 male cases and 339 controls showed that increased risk was associated with Type B behaviour, and independently with limited social contact. Discussion focuses on issues surrounding the use of retrospective, proxy data; and on the speculation that Type A behaviour may increase risk of non-fatal coronary events, but protect against coronary death.     

Cognitive predictors of posttraumatic stress symptoms six months following acute coronary syndrome

This study examined patients’ illness representations assessed shortly after an acute coronary syndrome (ACS) as predictors of posttraumatic stress symptoms six months later. Illness representations were assessed in ACS patients using standard measures at a home visit three weeks after discharge from hospital. Posttraumatic stress symptoms were assessed at the same time, and again six months later. Patients were aged 61 years on average, the majority being men (89.8%) of white European decent (89%). Greater posttraumatic symptoms at six months were associated with beliefs that the illness would last a long time (timeline), that it had an unpredictable time course (timeline – cyclical), greater consequences, less personal and treatment control, poorer illness coherence and stronger negative emotional representations (emotional upset relating to the illness; p?<?0.05). In multiple regression analyses, controlling for demographic, clinical and psychological factors (age, gender, ethnicity, social deprivation, ACS severity, negative affectivity and cardiac symptom recurrence), more intense emotional representations (β?=?0.146, p?=?0.041) and reduced illness coherence (β?=??0.133, p?=?0.029), emerged as independent predictors of posttraumatic symptom severity at six months. There was a near significant effect for personal control (β?=??0.113, p?=?0.058). These results demonstrate the importance of illness representations of ACS in predicting longer-term posttraumatic stress symptoms.     

A biopsychosocial model for depressive symptoms following acute coronary syndromes

A partial latent structural regression analysis was used to evaluate the influence of perceived stress and coping resources on depression following acute coronary syndromes (ACS) in a sample of 113 participants (25 females and 88 males with a mean age of 57.61 years (SD = 12.63). Out of them, 55 participants were Australian born and 48 were born elsewhere, with 53 of the patients scoring in the mild to high depression range on the Beck Depression Inventory and the Cardiac Depression Scale. Perceived stress and coping resources, after controlling for age and smoking explained 89% of the variance in the latent variable depression. Higher perceived stress levels and fewer coping resources predicted higher levels of depression. Higher levels of perceived stress predicted fewer coping resources and fewer coping resources predicted higher levels of depression. There was a significant direct and indirect effect of perceived stress through coping on depression. Cognitive and physical coping resources were the best predictors of the depression construct. These results have potential implications for the treatment of depression post-ACS. In particular, cognitive and physical coping mechanisms and perceived stress reduction need to be addressed when treating depression post-ACS.
