煤工尘肺病理改变以小血管、细支气管和肺泡间隔纤维化为主,因此,煤工尘肺患者晚期常并发心脏病变,肺心病是导致煤工尘肺患者生命质量下降和死亡的主要并发症。心电图、超声心动图是诊断煤工尘肺肺心病的有效方法,探讨心电图及超声心动图检查在尘肺并发肺心病患者的诊断和观察病情变化及疗效中的价值,对延缓煤工尘肺患者病情发展,改善预后具有非常重要的意义。
Coal workers pneumoconiosis pathological changes of small blood vessels, bronchioles and alveolar septa-based, therefore, coal workers often complicated by heart disease in patients with pneumoconiosis, pulmonary heart disease is the leading cause of coal workers with pneumoconiosis decreased quality of life and death of the main complications. Electrocardiogram, echocardiography is an effective method to diagnose pneumoconiosis in coal workers ’pneumoconiosis. To explore the value of electrocardiogram and echocardiography in the diagnosis and observation of patients with pneumoconiosis complicated with pulmonary heart disease and its curative effect, to delay the development of coal workers’ pneumoconiosis, To improve the prognosis is of great importance.
