ABSTRACT
Left ventricular (LV) function is characterized by contraction in the longitudinal, radial, and circumferential planes. Previous studies of postexercise changes in LV function have assessed global indices of LV function. The purpose of this study was to use 2-dimensional (2D) strain analysis to examine LV function following marathon running in the circumferential, radial, and longitudinal planes, and to compare these data with other global and regional indices of function. Fifteen (mean ± SD: age, 32 ± 7 years; stature, 1.76 ± 0.08 m; body mass, 77.8 ± 8.2 kg) competitors in the London Marathon were echocardiographically assessed pre- and postrace. 2D strain (ejection fraction (EF), Doppler (early (E) and late (A) trans-mitral filling), tissue Doppler imaging (TDI) (systolic (S′) and early diastolic (E′) wall-motion velocities); TDI-derived longitudinal strain (εTDI), and systolic and diastolic strain rate (SRTDI); and 2D-derived peak circumferential, radial, and longitudinal strain (ε2D), and systolic and diastolic strain rate (SR2D) were examined. Differences pre- and postrace completion were assessed using paired t tests, with alpha set at 0.01. All participants completed the marathon in a mean time of 213 ± 41 min. A varied response was observed for measures of LV systolic and diastolic function following completion of the marathon (mean ± SD): EF, 63 ± 6 vs. 63 ± 7% (p > 0.01); E:A, 1.70 ± 0.37 vs. 1.17 ± 0.37; E′:A′, 2.36 ± 0.79 vs. 1.60 ± 0.57 (p < 0.01); mean longitudinal εTDI, 19.1 ± 5.1 vs. 17.5 ± 4.2% (p < 0.01); mean longitudinal diastolic SRTDI, 1.81 ± 0.54 vs. 1.58 ± 0.51·s-1 (p < 0.01); mean longitudinal systolic SR2D, 0.73 ± 0.21 vs. 0.97 ± 0.22·s-1 (p < 0.01); mean longitudinal diastolic SR2D, 0.94 ± 0.34 vs. 1.01 ± 0.23·s-1 (p > 0.01); mean radial systolic SR2D, 1.20 ± 0.15 vs. 1.45 ± 0.32·s-1 (p < 0.01); mean radial diastolic SR2D, 1.19 ± 0.25 vs. 1.29 ± 0.41·s-1 (p > 0.01); mean circumferential systolic SR2D, -1.09 ± 0.16 vs. -1.24 ± 0.18·s-1 (p < 0.01); and mean circumferential diastolic SR2D, -1.27 ± 0.28 vs. -1.22 ± 0.31·s-1 (p > 0.01). Marathon running promotes a varied echocardiographic response, with some functional parameters showing no change, some increasing, and some decreasing postexercise. This varied response likely reflects the complexities of cardiac function and highlights the need to adopt a multimodality approach when assessing cardiac function following exercise.
