1986年在拉萨使用微型心导管直接测量了12例高原健康人和7例高原性心脏病人的肺动脉压。以肺动脉收缩压>4kPa和/或平均压>2.67kPa做为判断肺动脉高压的标准,测量结果表明12例高原健康人肺动脉高压发生率为25％,7例高原性心脏病人肺动脉高压发生率为100％。作者认为高原健康人存在的肺动脉高压与高原性心脏病之间并无严格的界限,二者是一个病理生理过程中的两个阶段。
Pulmonary arterial pressure was measured directly in Lhasa using a miniature cardiac catheter in 12 healthy people in the plateau and in 7 patients with elevated heart disease in Lhasa. Pulmonary artery systolic blood pressure> 4kPa and / or mean pressure> 2.67kPa were used as the criteria for the determination of pulmonary hypertension. The results showed that the incidence of pulmonary hypertension in 12 healthy subjects was 25%, and the incidence of pulmonary hypertension in 7 patients with elevated heart disease was 100 %. The author believes there is no strict boundary between pulmonary hypertension and high altitude heart disease in healthy people in the plateau. Both of them are two stages in a pathophysiological process.
