Popis: 高所住民の心肺機能, および肺高血圧の頻度を明らかにするため, 我々はインド・ラダーク地方の地域住民242名を対象とし, 問診, 診察, 血液検査, 心電図検査, 呼吸機能検査, 心臓超音波検査を施行した. 男女ともに多血症を呈した住民は少なく, 呼吸機能低下や明らかな心不全徴候を含む慢性高山病を呈する住民はいなかった. 女性では左室駆出率が有意に高値で, ヘモグロビンと負の相関をしており, 周囲の環境に適応した結果と考えられた.
The aim of this study is to investigate cardiopulmonary function and pulmonary hypertension in healthy highlanders. We estimated 242 subjects (mean age, 55±13; male/female, 84/158). Blood pressure, pulse, SpO2, respiratory function, electrocardiography, echocardiography, chronic mountain sickness (CMS) score, and hemoglobin were measured. A few subjects had polycythemia and no one had CMS. The left ventricular ejection fraction in women was higher than that in men and had an inverse correlation with hemoglobin. This finding may represent a consequence of adaptation to the high-altitude environment.
