煤工尘肺患者脉压水平对冠心病的影响

目的探讨煤工尘肺患者脉压水平对冠心病的影响。方法选自2007年1月—2008年12月某煤矿现已脱离粉尘作业的男性煤工尘肺患者260例为研究对象(尘肺组),以某建筑公司无粉尘作业史的男性工人260例为对照组。对尘肺组与对照组进行一般情况调查、疾病史调查,同时测量血压、身高、体重,检查心电图、心脏超声及血脂。资料整理后,用SPSS13.0统计软件包分析并处理数据,尘肺组与对照组比较采用t检验和χ2检验,以P0.05为有统计学意义。结果尘肺组收缩压平均(131.67±15.94)mmHg]、舒张压平均(75.62±9.83)mmHg]水平均低于对照组平均(137.01±18.69)mmHg、(84.25±10.31)mmHg)];脉压平均(55.86±13.96)mmHg)]水平高于对照组平均(52.83±15.02)mmHg];尘肺组冠心病患病率高于对照组,差异有统计学意义(P0.05);不同期别煤工尘肺患者冠心病患病情况比较,差异无统计学意义(P0.05);无论脉压60mmHg或≥60mmHg,尘肺组冠心病患病率均高于对照组(P0.05)。结论煤工尘肺患者冠心病患病率高于对照组,无论是尘肺组还是对照组,患冠心病的危险性均随脉压水平的增加而增加。未发现尘肺期别对尘肺患者冠心病的患病率有影响。

Influence of Pulse Pressure Level of Patients with Coal Worker Pneumoconiosis on Coronary Heart Disease

Objective]To study the influence of pulse pressure level of pneumoconiosis coal workers on coronary heart disease.Methods]Totally 260 male coal workers with pneumoconiosis who had been separated from dust work were selected as study objects (pneumoconiosis group),260 male workers without dust exposure from a construction enterprise were selected as control group.The general investigation and disease history investigation were performed on pneumoconiosis group and control group,as well as simultaneous surv...
