研究表明,感染可通过细胞因子介导的全身反应导致左、右心室射血分数(EF)降低,并且增加两心室的舒张末期和收缩末期容积。SARS是以超强的免疫反应为特征,由一种变异的冠状病毒(SARS-CoV)引起的传染病,SARS患者是否有类似的左心室功能障碍目前还不清楚。 方法 研究对象为46例被确诊为SARS的患者,在感染的急性期和第30天做经胸超声心动 Studies have shown that infection can lead to a decrease in left and right ventricular ejection fraction (EF) through cytokine-mediated systemic reactions and an increase in both ventricular end-diastolic and end-systolic volumes. SARS is characterized by a strong immune response, an infectious disease caused by a variant coronavirus (SARS-CoV), and it is unclear whether patients with SARS have similar left ventricular dysfunction. Methods Forty-six patients diagnosed with SARS underwent transthoracic echocardiography at the acute and 30th day of infection
