左心疾病相关肺动脉高压流行病学

Epidemiology of Pulmonary Hypertension due to Left Heart Disease

肺动脉高压是左侧心力衰竭的一种常见的并发症,与左室射血分数无关。左心疾病相关肺动脉高压属于第二类肺动脉高压,是其最常见的一种类型,并且有着较高的患病率及病死率。与其他类型的肺动脉高压(如特发性肺动脉高压)相比,左心疾病相关肺动脉高压的流行病学数据少得多;但近年来,人们对于左心疾病相关肺动脉高压的关注度越来越高。现将国内外有关左心疾病相关肺动脉高压的流行病学数据进行简要综述,旨在了解国内外左心疾病相关肺动脉高压流行病学情况,以及这些研究带来的启示。

Pulmonary hypertension（ PH） is a common complication of left heart failure,which is not related to the left ventricular ejection fraction. Left heart disease（ LHD） due to PH is classified as group 2,is believed to be the most common cause of PH and is associated with high morbidity and mortality. Epidemiology studies of PH-LHD are less exhaustive than others such as idiopathic PH,but in recent years,research on this topic has grown rapidly. In this review,current epidemiology of group 2 PH research from around the world are reviewed,along with the implications of these studies.
