The presence of cor pulmonale at death in relation to other factors such as emphysema, silicosis, and thromboembolism was analysed in a case-control study of 732 South African gold miners. Marked emphysema was the highest risk factor with an odds ratio of 21.32 (95% confidence interval (95% CI) 5.02-90.7), then extensive silicosis (OR 4.95, 95% CI 2.92-8.38) and thromboembolic disease (OR 1.92, 95% CI 1.37-2.69). Age and smoking were not significant predictors of cor pulmonale.
在一项针对732名南非金矿工人的病例对照研究中,分析了死亡时肺心病与其他因素(如肺气肿、矽肺和血栓栓塞)之间的关系。明显的肺气肿是最高风险因素,优势比为21.32(95%置信区间(95%CI)5.02 - 90.7),其次是广泛矽肺(优势比4.95,95%CI为2.92 - .38)和血栓栓塞性疾病(优势比1.92,95%CI为1.37 - 2.69)。年龄和吸烟并非肺心病的显著预测因素。
