A 34-year-old woman with biopsy-proved pulmonary alveolar microlithiasis is described. Cardiac catheterization data and results of pulmonary function studies are presented. Mild to moderate pulmonary hypertension occurred with supine leg exercise, possibly reflecting a reduced capacity of the vascular bed evident only with increased pulmonary blood flow and tachycardia. Attention should be paid to the level of physical activity in patients with this disease, particularly if the vital capacity is reduced below 80 percent of that predicted.
报道了一名经活检证实患有肺泡微石症的34岁女性。文中呈现了心脏导管插入术数据及肺功能研究结果。仰卧位腿部运动时出现轻度至中度肺动脉高压，这可能反映出仅在肺血流量增加和心动过速时才明显的血管床容量降低。对于患有这种疾病的患者，应注意其身体活动水平，尤其是当肺活量降至预测值的80%以下时。
