慢性肺原性心脏病28例临床与病理分析

Clinical Analysis of 28 Autopsies with Chroniccor Pulmonale

本文对28例肺心病的肺原发疾病分布及其死因进行了分析。发现2/5的病例左室厚度正常,3/5的病例左室增厚,后者的57％同时合并有冠心病或高血压,左室肥厚为综合因素引起,其余43％的病例不合并其他心脏病,理应认为由肺心病引起。还发现其肥厚程度与心衰史长短有关,5年以内者不肥厚。5年以上者多肥厚,心衰史越长,肥厚越显著。

The constitution of primary pulmonary diseases and causes of death in 28 cases of cor pulmonale were analysed. We found that 2/5 of the cases had normal left ventricles and 3/5 with left ventricular hypertrophy Among the hypertrophy group, 57％ of the patients were complicated with coronary heart disease or hypertension. of suggested that the causes of hypertrophy were comprehensive, The other 43％ cases were not complicated with other heart diseases. Their ventricular hypertrophy should be cousidered due to cor pulmonale alone. We also found that there was correlation between the degree of hypertrophy and the duration of cardiac failure. There was no hypertrophy cases with the duration of cardiac failure under 5 years. The left ventricular hypertrophy happened mostly in the patients had the duration longer than 5 years and the longer the duration of cardiac failure, the more severe the hypertrophy was.
