Abstract

Aims To obtain the normal ranges for 2D echocardiographic (2DE) indices of myocardial work (MW) from a large group of healthy volunteers over a wide range of ages and gender.

Methods and results A total of 226 (85 men, mean age: 45 +/- 13 years) healthy subjects were enrolled at 22 collaborating institutions of the Normal Reference Ranges for Echocardiography (NORRE) study. Global work index (GWI), global constructive work (GCW), global work waste (GWW), and global work efficiency (GWE) were estimated from left ventricle (LV) pressure-strain loops. Peak LV systolic pressure was non-invasively derived from brachial artery cuff pressure. The lowest values of MW indices in men and women were 1270mmHg% and 1310mmHg% for GWI, 1650mmHg% and 1544mmHg% for GCW, and 90% and 91% for GWE, respectively. The highest value for GWW was 238mmHg% in men and 239mmHg% in women. Men had significant lower values of GWE and higher values of GWW. GWI and GCW significantly increased with age in women.

Conclusion The NORRE study provides useful 2DE reference ranges for novel indices of non-invasive MW.
