ABSTRACT
Introduction: Advances in early detection and treatment of cancer have significantly reduced mortality. The net result is the emergence of a cohort of patients whose survival is sufficient to evidence the side effects of the used therapies. Cardiotoxicity is the set of cardiovascular diseases resulting from onco-hematological treatments.Objectives: To evaluate the role of global longitudinal strain in the early detection of cardiotoxicity in patients undergoing chemotherapy.
Method: A quantitative, analytical, prospective, longitudinal study was carried out in 44 patients diagnosed with breast cancer or lymphoma, who started chemotherapy treatment at the Instituto de Oncología y Radiobiología of Cuba, from February 2017 to April 2018. Primary and secondary methods were used for raw data collection and several statistical tests were used for its analysis.
Results: The mean age and treatment period were 47.7 years old and 5.05 months, respectively. The most prevalent risk factor was high blood pressure and cardiotoxicity was higher (27.8%) in patients with previous diastolic dysfunction. Among those who developed cardiotoxicity, the variable that showed the greatest affectation was global longitudinal strain (p<0.0001), with a reduction of 19.6% with respect to the basal one.
Conclusions: Global longitudinal strain is an echocardiographic index of myocardial performance, which presented a significant discriminating value with respect to cardiotoxicity in patients who received chemotherapeutic treatment.
