Echocardiographic reference ranges for noninvasive left ventricular 18-segment myocardial work index and work efficiency in a healthy Asian population.
Background: Left ventricular (LV) myocardial work index (WI) and work efficiency (WE) have become the latest indicators for assessing LV function. Reference ranges for normal LV segmental WI and WE have not been established.
Methods: Four hundred eleven healthy Asian subjects (47% men, median age: 35 years) were enrolled prospectively. WI and WE were analysed using the LV pressure-strain loop (LVPSL) with specific software.
Results: WI and WE differed significantly between segments as well as between walls and levels of the left ventricle. The anteroseptal basal segment had the lowest WI and WE (1440 mmHg ± 324 and 92% [88-96], respectively) among the eighteen segments. Significant WI and WE differences were found between sexes and age groups. No correlation was observed between age groups and the average WI of any wall or level in men, while the average WI of several different walls and levels in women showed significant differences between age groups. The average WI of most walls and levels increased with age in women. No correlation was found between age groups and the average WE of any wall or level in either men or women.
Conclusions: This study establishes the normal reference values of WI and WE of eighteen segments for clinical work and clinical experiments. There were significant differences in WI and WE between segments, levels, and walls of the normal left ventricle. Sex should be considered when analysing WI and WE. Age should be considered when analysing WI in women.
期刊介绍：
Cardiovascular Ultrasound is an online journal, publishing peer-reviewed: original research; authoritative reviews; case reports on challenging and/or unusual diagnostic aspects; and expert opinions on new techniques and technologies. We are particularly interested in articles that include relevant images or video files, which provide an additional dimension to published articles and enhance understanding.
As an open access journal, Cardiovascular Ultrasound ensures high visibility for authors in addition to providing an up-to-date and freely available resource for the community. The journal welcomes discussion, and provides a forum for publishing opinion and debate ranging from biology to engineering to clinical echocardiography, with both speed and versatility.
