Abstract

Background: Reliable quantification of stroke volume (SV) and left ventricular ejection fraction (LVEF) is essential for point-of-care assessment in hemodynamically compromised patients. Handheld echocardiography (HHE) equipment has entered the market a few years ago and is now available for clinical use. However, the performance of HHE for SV and LVEF quantification in comparison to cardiac magnetic resonance (CMR) imaging as golden standard is yet unknown.

Methods: Twenty volunteers were scanned with HHE, standard echocardiography (SE), and CMR. LVEF and SV were measured with each modality, and their accuracy and precision were evaluated.

Results: Bias and limits of agreement (LOA) between HHE and CMR were -0.21% (-2.89: 2.48) and 11.24% (-15.79: 15.59) for LVEF and 29.85 ml (22.13: 37.57) and 32.34 ml (-15.01: 44.86) for SV, respectively. Bias and LOA between SE and CMR were -0.60% (-3.74:2.55) and 13.16% (-18.85:18.26) for LVEF and 32.08 ml (24.61:39.54) and 31.34 ml (-11.29:43.37) for SV, respectively.

Conclusion: HHE versus CMR showed comparable accuracy and precision compared to SE versus CMR.

手持超声心动图与心脏磁共振在卒中量和左心室射血分数定量方面的比较

背景：可靠地量化每搏量（SV）和左心室射血分数（LVEF）对于血流动力学受损患者的护理点评估至关重要。手持式超声心动图（HHE）设备几年前已进入市场，现在已可用于临床。然而，与作为黄金标准的心脏磁共振成像（CMR）相比，HHE 在 SV 和 LVEF 定量方面的性能尚不清楚：方法：对 20 名志愿者进行 HHE、标准超声心动图 (SE) 和 CMR 扫描。方法：对 20 名志愿者进行 HHE 扫描、标准超声心动图扫描和 CMR 扫描，分别测量 LVEF 和 SV，并评估其准确性和精确性：HHE 和 CMR 测量 LVEF 的偏差和一致性界限（LOA）分别为 -0.21% (-2.89: 2.48) 和 11.24% (-15.79: 15.59)，测量 SV 的偏差和一致性界限（LOA）分别为 29.85 ml (22.13: 37.57) 和 32.34 ml (-15.01: 44.86)。SE和CMR的偏差和LOA分别为：LVEF为-0.60%（-3.74:2.55）和13.16%（-18.85:18.26），SV为32.08毫升（24.61:39.54）和31.34毫升（-11.29:43.37）：与SE和CMR相比，HHE和CMR的准确性和精确度相当。

期刊介绍： The Journal of Medical Ultrasound is the peer-reviewed publication of the Asian Federation of Societies for Ultrasound in Medicine and Biology, and the Chinese Taipei Society of Ultrasound in Medicine. Its aim is to promote clinical and scientific research in ultrasonography, and to serve as a channel of communication among sonologists, sonographers, and medical ultrasound physicians in the Asia-Pacific region and wider international community. The Journal invites original contributions relating to the clinical and laboratory investigations and applications of ultrasonography.
