CMR-TSI and outcome of CRT. Kaplan-Meier estimates of the time to the composite endpoint of death from any cause or hospitalization for a major cardiovascular event (MCE) after CRT.. Patients were stratified according to a pre-implant CMR-TSI < 110 ms or CMR-TSI ≥ 110 ms. Results of univariate Cox proportional hazards analyses are expressed in terms of the hazard ratio (HR) and 95% confidence limits. Reproduced with permission from Chalil S, et al.
