肺心病主要表现在右心室肥大和扩张,最简单的诊断方法是在肺动脉瓣下2cm处测右心室心肌的厚度,国内外都以该处之厚度>0.5cm作为诊断标准。但广西籍人个体普遍比较小,心脏包括右室均较轻而薄。本组正常右心室厚度平均值为0.33cm,比国内正常平均值0.48cm薄许多;8例肺心病平均厚度只有0.47cm,尚略低于全国正常平均值水平。因此,广西不能用右心室厚度>0.5cm作为诊断肺心病标准,否则势必漏诊许多病例。本组正常右心室的重量平均值为50克,较国外正常标准65克小很多;8例肺心病右室平均值为70克,与国外相同,说明本组肺心病例右室肥大是显著的。左右室之比值(L+S)/R反映右室相对大小,不受体型大小之影响,本组平均比值为1.95,支持国外提出以(L+S)/R<2作为肺心病诊断标准。
Pulmonary heart disease is mainly manifested in right ventricular hypertrophy and expansion, the simplest diagnostic method is to measure the thickness of right ventricular myocardium 2cm below the pulmonary valve, both at home and abroad to the thickness of> 0.5cm as a diagnostic criteria. However, individuals in Guangxi are generally relatively small, including the right ventricle, the heart is relatively light and thin. The average right ventricular thickness in this group was 0.33cm, which was much thinner than the normal 0.48cm in China. The average thickness of 8 cases of pulmonary heart disease was only 0.47cm, which was still slightly lower than the national normal average level. Therefore, Guangxi can not use the right ventricular thickness> 0.5cm as a diagnostic criteria for pulmonary heart disease, otherwise it is bound to miss a lot of cases. This group of normal right ventricle weight average of 50 grams, 65 grams smaller than the normal foreign standards; 8 cases of cor pulmonale average of 70 grams of right ventricle, the same as abroad, indicating that this group of patients with pulmonary heart disease, right ventricular hypertrophy is significant . (L + S) / R reflects the relative size of the right ventricle, regardless of the size of the body size, the average ratio of 1.95, to support the proposed foreign (L + S) / R <2 as the diagnostic criteria for pulmonary heart disease .
