对移居高原4 000m 20年内61名体力劳动者摄后前位胸片,按居住年限梯度,自体对照并分析其x线心血管四项指标。结果表明,肺动脉段突度和右肺下动脉横经变化是反映高原肺动脉高压轻重程度的敏感指标对高原性心脏病判定有一定的参考价值。观测x线各指标的改变,对高原肺动脉高压及高原性心脏病发病的监测具有一定的临床价值。对移居高原者,早期定时定期拍摄x线胸片具有一定的临床实用意义。
61 000 manual laborers of the ex-chest radiograph after 4 000 m migrating to the plateau within 20 years were analyzed by autopsy and four cardiovascular indicators of x-ray according to their length of stay. The results show that the pulmonary artery segment and the right inferior pulmonary artery transverse changes reflect the degree of severity of altitude sickness of pulmonary hypertension sensitive indicators for the determination of high altitude heart disease have a certain reference value. Observation of changes in the various indicators of x-ray, high altitude pulmonary hypertension and monitoring of the incidence of heart disease has some clinical value. For those who migrate to plateau, regular early x-ray chest film has some clinical significance.
