BACKGROUND
Coronary heart disease (CHD) is an impending global pandemic in developed countries as well as developing countries and economies in transition, such as India. A significant increase in the incidence of myocardial infarction (MI), one of the most common types of CHD, is being reported in India, and the incidence and severity of the disease are more among the youth in Kerala. Studies assessing the association between psychological factors and MI are few in India.
METHODS
We adopted a case-control study design. A total of 150 cases (with MI) and 150 controls (without MI and matched for age and gender) from a tertiary care hospital in Trivandrum, Kerala, India, were selected using convenient sampling method, between September 2016 and August 2017.
RESULTS
As compared to 33.3% of the controls, 50.7% of patients with MI had type D personality characteristics. Multivariate logistic regression analysis after adjusting for the confounders indicated a positive and statistically significant association between type D personality and MI: OR = 4.14, 95% CI = 2.19-8.85, P = 0.003.
CONCLUSION
Type D personality is associated with MI.
背景
冠心病（CHD）在发达国家以及发展中国家和经济转型国家（如印度）中已成为迫在眉睫的全球大流行病。据报道，印度冠心病最常见类型之一——心肌梗死（MI）的发病率显著上升，且喀拉拉邦年轻人中该疾病的发病率和严重程度更高。在印度，评估心理因素与心肌梗死之间关联的研究较少。
方法
我们采用病例对照研究设计。2016年9月至2017年8月期间，采用方便抽样法，从印度喀拉拉邦特里凡得琅一家三级护理医院选取了150例（患有心肌梗死）病例和150例对照（未患心肌梗死且年龄和性别匹配）。
结果
与33.3%的对照相比，50.7%的心肌梗死患者具有D型人格特征。在对混杂因素进行调整后的多因素逻辑回归分析表明，D型人格与心肌梗死之间存在正向且具有统计学意义的关联：比值比（OR）=4.14，95%置信区间（CI）=2.19 - 8.85，P = 0.003。
结论
D型人格与心肌梗死有关。
