Abstract
Aim. To assess the structure and performance of left atrium (LA) before and after 3 cycles of anticancer treatment in lymphoma patients, as well as the incidences of supraventricular arrhythmia (SVA) and the levels of biomarkers of inflammation. Material and Methods. This is a prospective observational study of patients with confirmed diagnosis of lymphoma [n=23; 57% men; median age 52 (34;64) years], who had no prior polychemotherapy. The comparison group included persons without lymphoma [n=18; 50% men; median age 43 (37; 54) years] comparable with the main group in terms of sex, age and risk factors for cardiovascular diseases. Patients with lymphoma underwent 24h-ECG monitoring and advanced transthoracic echocardiography at baseline and after 3 cycles (within 3 months) of anticancer treatment. Biomarkers of inflammation were measured. The results were compared with the data of the comparison group. Results. In lymphoma patients, LA reservoir, conduit, and booster function were found to be impaired at baseline but were comparable with these in matched controls. After 3 cycles of anticancer treatment, a trend to reduction of LA booster and conduit strain was found. The proportion of those with SVA was significantly higher in lymphoma patients before chemotherapy compared to those after anti-cancer treatment or controls: 57% vs 10% and 33% respectively (pS=0.44; pact) and ESR (rS=0.42, pS=0.43, pact and neuregulin-1β (rS=0.42, pS=0.55, pConclusions. In lymphoma patients, LA phasic strain parameters were impaired regardless of anticancer treatment. The associations between inflammatory biomarkers with SVA and parameters of LA performance were found.Keywords
