目的通过比较接触煤矿粉尘和噪声的职业人群与仅接触煤矿粉尘的职业人群的心血管疾病易感因素之间的差异,探索噪声对心血管疾病易感因素的影响。方法用现况研究方法,对观察组和对照组的一般情况和心血管易感因素进行统计分析。结果观察组收缩压、舒张压异常率,以及高血压Ⅰ级发生率较对照组高,且两组之间差异有统计学意义(P<0.05)。观察组与对照组心电图窦性心动过速改变差异有统计学意义(P<0.05)。动脉粥样硬化指数(AI)观察组与对照组的差异有统计学意义(P<0.05)。结论长期的噪声接触可对接噪人员心血管易感因素产生影响。 Objective To explore the effect of noise on susceptibility to cardiovascular diseases by comparing the differences in cardiovascular disease susceptibility between occupational groups exposed to dust and noise from coal mines and those exposed to coal dust. Methods Using the current research methods, the statistical analysis was made on the general situation and the cardiovascular predisposition factors of the observation group and the control group. Results The systolic blood pressure, diastolic blood pressure anomalous rate and the incidence of hypertension grade Ⅰ in the observation group were higher than those in the control group, and there was a significant difference between the two groups (P <0.05). The changes of electrocardiographic sinus tachycardia in observation group and control group were statistically significant (P <0.05). The difference between atherosclerosis index (AI) observation group and control group was statistically significant (P <0.05). CONCLUSIONS Long-term noise exposure can have an impact on the cardiovascular risk factors for noise officers.
