The association of reduced global longitudinal strain with cancer therapy-related cardiac dysfunction among patients receiving cancer therapy
2020
Overview
BackgroundCardiotoxicity is a leading cause of morbidity and mortality among patients receiving cancer therapy. The most commonly used definition is cancer therapy-related cardiac dysfunction (CTRCD) defined by a left ventricular ejection fraction reduction. Global longitudinal strain (GLS) has been implied to be superior in detecting early subclinical dysfunction.ObjectivesEvaluate the prevalence of reduced GLS and whether it is associated with CTRCD development among patients receiving cancer therapy.MethodsData were collected as part of the Israel Cardio-Oncology Registry (ICOR), a prospective registry enrolling all adult patients receiving different types of cancer therapy, who were referred to the cardio-oncology clinic. Patients were divided into two groups—reduced GLS (> − 17%) vs. preserved GLS (≤ − 17%). Multivariable analyses were adjusted for a propensity score for baseline characteristics.ResultsAmong 291 consecutive patients, 48 (16%) patients were included in the reduced GLS group. Overall, 11 (5%) patients developed CTRCD at following echocardiogram evaluation. Patients with preserved GLS had a significantly lower risk for CTRCD development [odds ratio (OR) 0.11, 95% confidence interval (CI) 0.03–0.41, p = 0.001], with every 1-unit improvement of GLS the risk of CTRCD decreased by 16% (OR 0.84, 95%CI 0.73–0.95, p = 0.007). After adjustment for baseline characteristics, including cardiovascular risk factors and systolic function, preserved GLS remained significantly associated with a lower risk for CTRCD development (OR 0.11, 95%CI 0.02–0.64, p = 0.014), with every 1-unit improvement lowering the risk by 19% (OR 0.81, 95%CI 0.67–0.98, p = 0.032).ConclusionsReduced GLS is common among patients receiving cancer therapy and may identify patients at increased risk for CTRCD development.Graphic abstract
