Abstract/OtherAbstract:
AIMS: Asymptomatic long-term cancer survivors treated with anthracycline were investigated for late anthracycline cardiotoxicity using dobutamine stress echocardiography (DSE) and tissue Doppler (TD) velocities.
METHODS AND RESULTS: The study comprised 20 asymptomatic patient and 18 healthy children as the control group. Twenty patients were divided into two groups according to the myocardial wall motion during DSE: Group 1 (normal myocardial wall motion; six girls and five boys) and Group 2 (abnormal myocardial wall motion: nine boys). Intravenous dobutamine infusion was started at a dose of 5 µg/kg/min (D5) and gradually increased to 10 (D10), 15 (D15) and 20 µg/kg/min (D20). Echocardiographic assessment was performed at rest and after each dose of dobutamine infusion. Abnormal myocardial wall motion was observed at rest in 3 patients and during DSE in six patients. There were no significant differences between the patients and control groups at rest except the end systolic wall stress and mitral deceleration time measured by conventional methods; however, both patients group showed significant differences of systolic and diastolic functions at D20. In patients groups, systolic and diastolic functions of interventricular septum (IVS) and systolic function of left ventricle (LV) and right ventricle (RV) TD velocities showed significant changes compared with control group at rest. Significant differences of diastolic functions of IVS and RV were noted during dobutamine infusion in abnormal myocardial wall motion compared with other groups.
CONCLUSION: LV, RV and IVS TD velocities systolic function at rest and during DSE can provide valuable information for early detection of subclinical cardiac toxicity. TD velocities of diastolic functions during DSE are a valuable parameter for assessment of subclinical cardiac toxicity in patient with abnormal wall motion.
