肺心病左室舒张功能障碍发病机制的研究进展

摘要

In recent years, the incidence of pulmonary heart disease has increased year by year. In the past, the influence of pulmonary heart disease on the heart was mainly due to right heart dysfunction, which did not affect left heart function. Left heart dysfunction was mainly caused by primary left heart disease, but in recent years, many literatures indicate that pulmonary heart disease caused by long-term development of chronic obstructive pulmonary disease can be combined with left ventricular dysfunction in the early stage, mainly with left ventricular diastolic dysfunction. This article mainly describes the causes of left ventricular diastolic dysfunction in patients with pulmonary heart disease caused by long-term development of chronic obstructive pulmonary disease from five different aspects, and summarizes the related literature.%近年来肺心病的发病率逐年上升, 以往认为肺心病对心脏的影响主要以右心功能障碍为主, 不影响左心功能, 左心功能障碍主要为原发左心病变所致, 但近年来不少文献指出由慢阻肺长期发展引起的肺心病在早期即可合并左心功能障碍, 主要以左室舒张功能障碍为主.本文主要从五个不同方面阐述由慢阻肺长期发展引起的肺心病患者左室舒张功能障碍的原因, 结合相关文献做一综述.
