Introduction Feature tracking strain analysis using cardiac magnetic resonance (CMR) imaging enables the appreciation of complex mechanics of the athlete’s heart without adding extra sequences and increasing image acquisition time. Purpose We evaluated the associations of the left (LA) and right atrial (RA) functional and strain parameters with sports activity and demographic characteristics in a large cohort of competitive athletes. We compared the athlete’s biatrial remodelling with healthy, sex-matched control subjects. Methods We performed a retrospective analysis on 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. We excluded images with foreshortening or apparent planning flaw. Subjects were categorized into four groups based on their weekly training loads ( 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 LA GLS only differed between the lowest and highest training volumes (p=0.048). LA GCS was higher in the least trained group (p Interestingly, the LA end-diastolic volume index was less (r=0.13, p=0.008) correlated to weekly training volume than the left ventricular end-diastolic volume index (r=0.51, p 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. Sophisticated atrial function characterization by strain analysis might provide novel insight into healthy sports adaptation. |
