The main objectives of this study were to assess the risk of contracting first episode of myocardial infarction (MI) subsequent to vibration exposure and to assess a possible exposure-response relationship.
The Västernorrland heart epidemiology programme (VHEEP, a part of the Stockholm heart epidemiology programme study) was the source of the data. VHEEP is a population-based case-control study of risk factors for acute MI. Exposure information was collected by questionnaire and vibration exposure was assessed in 218 cases and 257 controls. Relative risks were estimated using odds ratios (ORs) from binary logistic regression.
The results show that the OR of acute MI when exposed to vibration was 1.6 (95% CI: 1.1-2.4). It was not possible, however, to determine whether an exposure-response relationship was present.
Working entailing vibrating machines is associated with an increased risk for acute MI.
本研究的主要目的是评估振动暴露后首次发生心肌梗死（MI）的风险，并评估可能的暴露-反应关系。
韦斯特诺尔兰心脏流行病学项目（VHEEP，斯德哥尔摩心脏流行病学项目研究的一部分）是数据来源。VHEEP是一项基于人群的急性心肌梗死危险因素病例对照研究。通过问卷调查收集暴露信息，并对218例病例和257例对照进行振动暴露评估。使用二元逻辑回归的比值比（OR）估计相对风险。
结果显示，暴露于振动时急性心肌梗死的OR为1.6（95%CI：1.1-2.4）。然而，无法确定是否存在暴露-反应关系。
涉及振动机器的工作与急性心肌梗死风险增加有关。
