Abstract
We studied the physiologic and clinical responses to moderate altitude in 97 older men and women (aged 59 to 83 years) over 5 days in Vail, Colorado, at an elevation of 2,500 m (8,200 ft). The incidence of acute mountain sickness was 16%, which is slightly lower than that reported for younger persons. The occurrence of symptoms of acute mountain sickness did not parallel arterial oxygen saturation or spirometric or blood pressure measurements. Chronic diseases were present in percentages typical for ambulatory elderly persons: 19 (20%) had coronary artery disease, 33 (34%) had hypertension, and 9 (9%) had lung disease. Despite this, no adverse signs or symptoms occurred in our subjects during their stay at this altitude. Our findings suggest that persons with preexisting, generally asymptomatic, cardiovascular or pulmonary disease can safely visit moderate altitudes.
摘要
我们在科罗拉多州韦尔海拔2500米（8200英尺）处，对97名年龄在59至83岁之间的老年男性和女性进行了为期5天的中度海拔生理和临床反应研究。急性高山病的发病率为16%，略低于年轻人的报告发病率。急性高山病症状的出现与动脉血氧饱和度、肺活量测定或血压测量结果并不平行。慢性病的比例与非卧床老年人的典型比例相同：19人（20%）患有冠状动脉疾病，33人（34%）患有高血压，9人（9%）患有肺部疾病。尽管如此，我们的受试者在该海拔停留期间未出现任何不良体征或症状。我们的研究结果表明，患有先前存在的、通常无症状的心血管或肺部疾病的人可以安全地前往中度海拔地区。
