【摘要】 目的　探讨左心室受压所引起的单纯性左室舒张性心力衰竭 (LVDHF)临床特征。方法　(1)对 2 1例原发性肺癌直接压迫左室造成的单纯性LVDHF的临床表现进行回顾性分析。 (2 )对患者进行心电图、X线胸片、超声心动图、胸部CT、纤维支气管镜、细胞学和病理学等检查。结果　 (1)超声示2 1例左室腔狭小 ,EV AV异常增大 8例 ,伪正常 13例 ,LVEF均正常。 (2 )X线胸片示 2 1例呈间质性或肺泡性肺水肿。 (3)临床上 2 1例均有呼吸困难 ,肺部有湿口罗音和 (或 )肺泡呼吸音减弱。 (4)洋地黄类使临床症状加重。结论　左室受压所致LVDHF具有一般的单纯性LVDHF共同的临床特征 ,其临床表现与左室收缩性心力衰竭 (LVSHF)基本一样。不能迅捷但能逐级缓缓平卧且无阵发性夜间呼吸困难是左室受压所致LVDHF的较早期的特征性临床表现更多还原

【Abstract】 Objective To investigate the clinical feature about the heart failure of the simple diastolic left ventricle (LVDHF) caused for the left ventricular wall being constricted.Methods (1)We carried out a retrospective analysis of the clinical manifestation about the simple LVDHF caused by 21 cases of primary lung cancer directly constricting the left ventricular wall.(2)We examined the patients by having an electrocardiogram,chest X ray,echocardiography,chest CT,fiber bronchoscope,pathology and several cytology.Results (1)Echocardiography showed 21 patients’ left ventricular cavity got narrow and small.8 patients’ EV/AV unsually enlarged.13 cases were falsely normal.The LVEF were all normal.(2)Chest X ray showed 21 cases suffered from pulmonary interstitial or alveolar edema.(3)All 21 cases had dyspnea to varying degrees and pulmonary moist rales,their pulmonary alveolar respiratory sounds were weakened.(4)The digitalis caused more serious clinical symptons.Conclusion The simple LVDHF that is caused by the left ventricular wall being constricted has the same clinical feature as the common simple LVDHF does.Its clinical manifestation is the same as LVSHF on the whole.It is the characteristic clinical manifestation of LVDHF,which is caused by the left ventricular wall being constricted,to be unable to lie quickly but to lie slowly little by little without paroxysmal nocturnal dyspnea.更多还原
