慢性肺原性心脏病54例尸检病理诊断标准的分析

对54肺原性心脏病(肺心病)和7例对照组的尸检分析,认为慢性支气管炎(慢支)、肺气肿、支气管扩张(支扩)和肺血管床减少(肺纤维化)是导致肺动脉高压产生肺心病的主要原因,而肺结核病也是引起肺心病的重要因素。并认为肺心病的心脏病理诊断标准是:①心脏重量≥300g;②右心室壁厚≥0.5cm;③右心室腔扩张。“节瓣距”、右心室外弧长、肺动脉瓣和三尖瓣的周长均可作为右心室腔扩张的指标。

STANDARDS OF PATHOLOGICAL DIAGNOSES OF CHRONIC COR PULMONALE-ANALYSIS OF 54 AUTOPSIES

Autopsy reports on 54 cases of cor pulmonale and 7 cases of non-pulmonary disease were analyzed and discussed in regards to the causes of death and standards of pathological diagnosis.It is considered that chronic bronchitis, emphysema, bronchieotasis and pulmonary iibrosis with reduction of pulmonary vascularity cause pulmonary arterial hypertension which then produces cor pulmonale. Tuberculosis is also an important etiologio factor of cor pulmonale.Standards for pathologic diagnosis of cor pulmonale are: (1) the heart weighs more than 300g; (2) the right ventricular wall is equal to or thicker than 0.5 cm; (3) the right ventricular cavity is enlarged. "The distance from the moderator band to the pulmonary valve", external length of the right ventricle, circumferences of i h3 pulmonary and tricuspid valves are all larger than those without pulmonary disease (p<0.05-0.01).
