摘要
目的 探讨舒张性心力衰竭的临床特点。方法 对 30例舒张性心力衰竭患者的临床表现特点及X线、心超检查进行临床分析。结果 30例舒张性心力衰竭中 ,劳力性呼吸困难 2 8例 ,咳嗽、咳痰 2 2例 ,两中下肺湿罗音 2 6例 ,X线心胸比例 <0 5 1,心超左室舒张末期内径小于 6 0mm ,内径缩短率大于 2 5 % ,射血分数正常。结论 舒张性心力衰竭在冠心病、高心病、肥厚性心肌病、主动脉瓣狭窄等病中发生率高。治疗中钙拮抗剂为首选 。
Objective To study and discuss the clinical characteristics of diastolic heart failure in aged patients.Methods By means of X rays radiography,cardioultrasonatro,and others,30 patients were examined.The data given were carefully analyzed.Results Among the 30 patients:28 cases having exertion dyspnea,22 cases having dry cough and(or) productive cough,26 cases having moist rale at the middle and lower parts of both right and left lungs.For all the patients:ratio of heart and lung width as shown in the radiographs less than 0.51,inside diameter of the left ventricle at the later stage of diastole less than 60mm,with a shortening greater than 25 per cent and fraction of blood discharge normal.Conclusion The occurance frequency of diastolic heart failure is high among the patients suffering form the common disease as coronarism,cardiohypertension,hypertrophic cardiomyopathy,and angusty of aortic valve.Calcium antagonist is the first choice for therapy.Positive systolic medicament is not advised.
