1039 CARDIAC MRI EVALUATION FOR ATHLETES WITH NEGATIVE T WAVES AT ECG AND NORMAL TRANSTHORACIC ECHOCARDIOGRAPHY.

Abstract Introduction Negative T waves at ECG represent a common diagnostic dilemma in athletes. These subjects, often asymptomatic, undergo screening every year before practicing competitive sports. The clinical meaning of these abnormalities is unclear and comprehensive evaluation needed. Echocardiography the first step test all cases, but advent cardiac MRI field empowers capability for identification cardiovascular disease very early stage, even when transthoracic echocardiography normal. aim present study to define prevalence positive among athletes with negative normal predictors pathological or CT Material Methods A consecutive cohort findings were enrolled. All underwent 24h monitoring, exercise MRI; was performed only if clinically indicated subjects >35 years old age. type sport practiced recorded stratified according intensity into low- mid- high-intensity. site defined as “deep” wider than 2 mm. presence any arrhythmias during 24-ECG monitor well. primary end-point criteria structural heart Results total 55 (50 male, 90%) enrolled mean age 27 ± 14 years-old. Most them high-intensity sports activity (47 athletes, 85.4%). Anterior most (29 52.7%) 8 (14.5%) had more isolated ventricular ectopic beats 24-hours monitoring. Among entire cohort, 16 (29.1%) specific disease. Of interest, deep t (OR 8.1 95%CI 1.4–49.5, p<0.001) complex 5.5 1.1–26.6, significative associated echocardiography. Conclusions Our results identified 29% interest Thus, our results, advanced imaging techniques (cardiac CT) should be considered especially are present.
