The identification of diastolic heart failure (DHF) is important for determining the prognosis of congestive heart failure patients. This study attempted to determine the accuracy of emergency physicians who performed bedside echocardiography (BECH) in patients with diastolic dysfunction.
Three attending emergency physicians underwent 3 h of didactic and 3 h of hands-on training taught by a cardiology specialist for the echocardiographic diagnostic criteria of DHF. Between February and April 2010, the emergency physicians performed BECH for patients presenting with dyspnoea, and echocardiographic views were recorded. Our gold standard for the diagnosis of diastolic dysfunction was the cardiologists' echocardiography report. Results were compared with χ(2) testing.
Of the 69 enrolled patients, 51 were diagnosed as having diastolic dysfunction by emergency physicians. The sensitivity of BECH was 89% (77-95) and specificity was 80% (51-95) with 95% CI. The accuracy of the emergency physicians' echocardiographic diagnosis was 87%.
BECH performed by emergency physicians may serve as an objective, rapid, non-invasive tool in the assessment of patients presenting with dyspnoea in ED.
舒张性心力衰竭(DHF)的诊断对于确定充血性心力衰竭患者的预后非常重要。本研究试图确定在具有舒张功能障碍的患者中进行床边超声心动图(BECH)的急诊医师的准确性。
三位主治急诊医师接受了 3 小时的理论教学和 3 小时的由心脏病专家进行的实践培训,以了解 DHF 的超声心动图诊断标准。在 2010 年 2 月至 4 月期间,急诊医师对出现呼吸困难的患者进行了 BECH,并记录了超声心动图图像。我们将舒张功能障碍的诊断的金标准设为心脏病专家的超声心动图报告。结果用卡方检验进行比较。
在纳入的 69 名患者中,有 51 名被急诊医师诊断为舒张功能障碍。BECH 的灵敏度为 89%(77-95),特异性为 80%(51-95),95%CI 为 87%。急诊医师超声心动图诊断的准确性为 87%。
在 ED 中对出现呼吸困难的患者进行评估时,BECH 可能成为一种客观、快速、无创的工具。
