积极的情感被认为独立于消极的情感来预测心血管健康。在1995年新斯科舍省健康调查中，我们对1739名成年人(862名男性和877名女性)的积极情感与心血管事件之间的关系进行了调查，研究了积极情感水平较高是否与较低的冠心病(CHD)风险相关。训练有素的护士进行A型结构化访谈，编码员对外在表现出的积极影响程度进行五分制评分。为了检验积极情绪在控制抑郁症状和其他负面情绪时预测冠心病的发生，我们使用了协变量：流行病学研究中心抑郁症状量表、库克·梅德利敌意量表和斯皮尔伯格特质焦虑量表。在14916人年的观察中，有145例(8.3%)急性非致命性或致命性缺血性心脏病事件。在控制了年龄、性别和心血管危险因素的比例风险模型中，积极情感预测冠心病(调整后的HR，0.78；95%CI 0.63-0.96个百分点；P=0.02)，协变量抑郁症状继续预测冠心病，正如以前在相同患者中发表的那样(HR，1.04；95%CI 1.01-1.07每个百分点；P=0.004)，敌对和焦虑不能(P>；在这项基于人群的大型研究中，增加积极情绪对10年发生的冠心病具有保护作用，这表明预防策略不仅可以通过减少抑郁症状，还可以通过增加积极情绪来加强。
Positive affect is believed to predict cardiovascular health independent of negative affect. We examined whether higher levels of positive affect are associated with a lower risk of coronary heart disease (CHD) in a large prospective study with 10 years of follow-up.We examined the association between positive affect and cardiovascular events in 1739 adults (862 men and 877 women) in the 1995 Nova Scotia Health Survey. Trained nurses conducted Type A Structured Interviews, and coders rated the degree of outwardly displayed positive affect on a five-point scale. To test that positive affect predicts incident CHD when controlling for depressive symptoms and other negative affects, we used as covariates: Center for Epidemiological Studies Depressive symptoms Scale, the Cook Medley Hostility scale, and the Spielberger Trait Anxiety Inventory. There were 145 (8.3%) acute non-fatal or fatal ischaemic heart disease events during the 14 916 person-years of observation. In a proportional hazards model controlling for age, sex, and cardiovascular risk factors, positive affect predicted CHD (adjusted HR, 0.78; 95% CI 0.63-0.96 per point; P = 0.02), the covariate depressive symptoms continued to predict CHD as had been published previously in the same patients (HR, 1.04; 95% CI 1.01-1.07 per point; P = 0.004) and hostility and anxiety did not (both P > 0.05).In this large, population-based study, increased positive affect was protective against 10-year incident CHD, suggesting that preventive strategies may be enhanced not only by reducing depressive symptoms but also by increasing positive affect.
