Heart failure is a major source of cardiovascular morbidity, including acute decompensations requiring hospitalization. Because most therapeutic interventions in acute heart failure target optimization of cardiac output and volume status, accurate assessment of these parameters at the point of care is critical to guide management. However, physician bedside assessments of left ventricular (LV) function and volume status have limited accuracy. Traditional echocardiographic platforms, while useful for assessing ventricular and valvular function and volume status, have limitations for bedside use or frequent serial evaluation. Handcarried cardiac ultrasound devices, with their substantially lower costs, portability, and ease of use, circumvent many of the limitations of traditional echocardiographic platforms. The diagnostic capabilities of handcarried devices provide the opportunity for ultrasound assessment of LV function and serial bedside evaluation of volume status in patients with acutely decompensated heart failure.
心力衰竭是心血管疾病发病的主要原因,包括需要住院治疗的急性失代偿。由于急性心力衰竭的大多数治疗干预措施旨在优化心输出量和容量状态,因此在床边准确评估这些参数对于指导治疗至关重要。然而,医生在床边对左心室(LV)功能和容量状态的评估准确性有限。传统超声心动图平台虽然有助于评估心室和瓣膜功能及容量状态,但在床边使用或频繁进行系列评估方面存在局限性。便携式心脏超声设备成本大幅降低、便于携带且易于使用,克服了传统超声心动图平台的许多局限性。便携式设备的诊断能力为急性失代偿性心力衰竭患者的左心室功能超声评估和容量状态的床边系列评估提供了机会。
