Abstract

Aims: The variability of ejection fraction (EF) poses a problem in the assessment of left ventricular (LV) function in patients receiving potentially cardiotoxic chemotherapy. We sought to use global longitudinal strain (GLS) to compare LV responses to various cardiotoxic chemotherapy regimens and to examine the response to cardioprotection with beta-blockers (BB) in patients showing subclinical myocardial damage.

Methods and Results We studied 159 patients (4914 year, 127 women) receiving anthracycline (group A, n=53, 4617 year), trastuzumab (group T, n=61, 5312 year), or trastuzumab after anthracyclines (group AT, n = 45, 46 9 year). LV indices [ejection fraction (EF), mitral annular systolic velocity, and GLS] were measured at baseline and follow-up (77 months). Patients who decreased GLS by ≥11% were followed for another 6 months; initiation of BB was at the discretion of the clinician. Anthracycline dose was similar between group A and group AT (213118 vs. 21647 mg/m2, P=0.85). Although ΔEF was similar among the groups, attenuation of GLS was the greatest in group AT (group A, 0.72.8% shortening; T, 1.12.7%; and AT, 2.02.3%; P=0.003, after adjustment). Of 52 patients who decreased GLS by ≥−11%, 24 were treated with BB and 28 were not. GLS improved in BB groups (from −17.62.3 to −19.82.6%, P<0.001) but not in non-BB groups (from −18.02.0 to −19.03.0%, P=0.08). Effects of BB were similar with all regimens.

Conclusions GLS is an effective parameter for identifying systolic dysfunction (which appears worst with combined anthracycline and trastuzumab therapy) and responds to cardioprotection in patients administered beta-blockers.
