以急性心肌梗死、反复心衰为主要表现的重度主动脉瓣狭窄一例病例分享

Severe Aortic Stenosis with Acute Myocardial Infarction and Refractory Heart Failure as the Main Clinical Manifestations: A Case Report

主动脉瓣狭窄是临床上常见的一种心脏瓣膜病,其主要原因有先天性、老年性及风湿性。心绞痛、晕厥和劳力性呼吸困难是典型主动脉瓣狭窄的常见三联征,也可因心排量降低出现焦躁不安、疲乏、呼吸困难性发绀、左心衰及肺水肿,严重肺动脉高压时,可出现右心衰。治疗以手术为主,时机的掌握与患者预后关系密切。本文报道1例因急性非ST段抬高型心肌梗死、心力衰竭反复3次入院的老年患者,住院期间心脏彩超提示其主动脉瓣狭窄进行性加重,经瓣膜置换术后症状治愈。提示及时识别主动脉瓣狭窄患者临床症状对于指导主动脉瓣狭窄的诊断、治疗具有重要临床意义。

Aortic stenosis,a clinically commonvalvular heart disease,is congenital,senile,and rheumatic.As people aging,the incidence of senile aortic stenosis increases.Angina,syncope,andexertional dyspnea are common triads of typical aortic stenosis.However,dueto the decrease in cardiac output,there may also be anxiety,fatigue,anddifficulty in breathing happened simultaneously as by-side effects,which willcause heart failure and pulmonary edema.When severe pulmonary hypertensionoccurs,right heart failure may occur.Surgery is the main treatment for aorticstenosis,and the timing is closely related to the prognosis of patients.Thisarticle demonstrates the general diagnosis and treatment received by an elderlypatient with acute non-ST-segment elevation myocardial infarction and heartfailure during the three times admissions to hospital.Colour Dopplerechocardiography during hospitalization prompted a progressive aggravation ofaortic stenosis,and the symptoms were cured after valve replacement.It ishighly suggested that timely identification of clinical symptoms of patientswith aortic stenosis has important clinical significances on guiding the diagnosisand treatment of aortic stenosis.
