LV global longitudinal strain (GLS) is a less load-dependent measure of LV function. However, the prognostic value of LV GLS in secondary MR has not been evaluated. OBJECTIVES This study sought to demonstrate the prognostic value of LV GLS over LVEF in patients with secondary MR. METHODS A total of 650 patients (mean 66 ± 11 years of age, 68% men) with significant secondary MR were included. The study population was subdivided based on the LV GLS value at which the hazard ratio (HR) for all-cause mortality was >1 using a spline curve analysis (LV GLS less then 7.0%, impaired LV systolic function vs. LV GLS ≥7.0%, preserved LV systolic function). The primary endpoint was all-cause mortality. RESULTS During a median follow-up of 56 (interquartile range 28 to 106 months) months, 334 (51%) patients died. Patients with a more impaired LV GLS showed significantly higher mortality rates at 1-, 2-, and 5-year follow-up (13%, 23%, and 44%, respectively) when compared with patients with more preserved LV systolic function (5%, 14%, and 31%, respectively). On multivariable analysis, LV GLS less then 7.0% was associated with increased mortality (HR 1.337; 95% confidence interval 1.038 to 1.722; p = 0.024), whereas LVEF ≤30% was not (HR 1.055; 95% confidence interval 0.794 to 1.403; p = 0.711). CONCLUSIONS In patients with secondary MR, impaired LV GLS was independently associated with an increased risk for all-cause mortality, whereas LVEF was not. LV GLS may therefore be useful in the risk stratification of patients with secondary MR.
