ABSTRACT
BACKGROUND:
Strenuous and chronic exercise training can have detrimental effects on cardiac morphology and function. Our aim was to evaluate the cardiac adaptation between 2 different specialties' endurance athletes marathon runners (M) and ultra-trailers (UT).METHODS:
47 M (age 45±7, men 32; training 18 (9-53) years*days/week), 41 UT (age 42±9, men 38, training 30 (15-66) years*days/week) were submitted in rest condition to conventional 2D echocardiography and Speckle-Tracking echo (STE) (Beyond Diogenes 2.0, AMID) during agonistic season and compared with 15 age matched sedentary individuals (S) (age 43±6, men 10).RESULTS:
Left ventricle (LV) global longitudinal strain (GLS) and global radial strain (GRS) were increased in M and UT compared to S (see table) without differences in LV anatomy and function. Right ventricle (RV) end-diastolic area (p=0.026), fractional area changing (p=0.008) and RV GLS were increased in UT compared to M. Moreover UT showed larger right atrium (RA) volume compared to M (p=0.03) and S (p=0.003). RA GLS was reduced in UT compared to M while the RA Global Circumferential Strain was significantly increased in UT. After adjusted for age, sex and HR as covariates, UT showed a reduced RA GLS (OR 0.907; CI 0.856-0.961) and increased RV FAC (OR 1.172; CI 1.044-1.317) compared to M; while when compared to S subjects, UT showed increased RA volume (OR 1.048; CI 1.002-1.096) and RV GLS (OR 0.667; CI 0.490-0.907).CONCLUSION:
UT showed higher RV and RA morphological and functional remodeling in comparison with M. 2D-STE is a useful tool to investigate the deformation dynamic in different sport specialties. Further studies will be necessary to clarify the long-term consequences for cardiac health due to myocardial perturbations.MUTSpLV GLS-28.59±3.43*-27.64±4.18*-24.82±4.53<0.05LV GRS69.85±8.94*66.59±11.19*56.27±16.25<0.001RV GLS-25.60±10.54-30.41±4.38*-27.10±4.64<0.05RA GLS37.15±13.4931.65±9.60*35.37±9.99<0.05RA GCS17.46±6.4222.28±8.97*23.37±6.47<0.01.
