Introduction: Feature tracking cardiac magnetic resonance (CMR) imaging enables the appreciation of complex mechanics of the heart without adding extra sequences and increasing image acquisition time.
Aims: We evaluated the associations of the left (LA) and right atrial (RA) functional and strain parameters with sports activity and demographic characteristics in a cohort of competitive athletes and compared them with healthy, sex-matched control subjects.
Methods: We analyzed native CMR cine images acquired between 2009 and 2021. Standard two-chamber and four-chamber long-axis cine movies were analyzed using Medis Suite software. Subjects were categorized based on their weekly training loads (<6 h, 6-10 h, 11-20 h and 21 h<).
Results: We performed CMR on 510 subjects, of which 375 were highly trained athletes (median age 20 ys, IQR 16-25; 244 male). A group of 135 healthy volunteers [median (mdn) age 25 ys, IQR 23-28, 64 male] served as controls. Left atrial global longitudinal strain (GLS) was lower (p=.002) in athletes (mdn 41%) than in controls (mdn 43%), whereas RA GLS showed a more pronounced decrease (mdn 32% vs 43%, p<.0001). Between male athletes and controls, LA global circumferential strain [(GCS), mdn 40% vs 47%, p=.0001], LA conduit (mdn 26% vs 28%, p=.025), RA GLS (mdn 31% vs 38%, p<.0001), and RA GCS (mdn 17% vs 20%, p=.024) strain values showed a difference. Between female athletes and controls, RA GLS (mdn 34% vs 44%, p<.0001), RA GCS (mdn 19% vs 29%, p<.001), RA booster (mdn 9% vs 13%, p=.006), and RA conduit (mdn 25% vs 32%, p<.001) were significantly different, while LA strain values were comparable. We found a significant difference between male and female athletes in LA GLS (mdn 39%, vs 43%, p=.0001), LA GCS (mdn 40% vs 42%, p=.01) and LA conduit strain (mdn 26% vs 29%, p<.001). In the right atrium, GLS (mdn 31% vs 34%, p=.047) and conduit strain (mdn 21% vs 25%, p=.004) were significantly lower in male athletes.
LA GLS only differed between the lowest and highest training volumes (p=0.048). LA GCS was higher in the least trained group (p<.001) than in the other three categories.
Conclusion: The atrial adaptation of the athlete’s heart shows distinct mechanic properties, which are further stratified with exercise level and sex. The RA seems to be more prone to increasing exercise load than the LA.
