Table 3 Comparison of the RA reservoir, conduit and booster pump function between HCM patients and normal subjects by detecting the RA Strain and strain rate (mean ± SD)

From: Right atrial function assessed by volume-derived values and speckle tracking echocardiography in patients with hypertrophic cardiomyopathy

Variable Values P Value
HCM(32) Normal(34)
S-reservoir(%) 29.42 ± 12.02 41.99 ± 14.58 < 0.001
S-conduit(%) 14.70 ± 7.61 23.95 ± 9.69 < 0.001
S-booster pump(%) 14.72 ± 6.45 18.04 ± 7.13 0.052
Sr-reservoir(S−1) 1.40 ± 0.56 1.90 ± 0.67 < 0.001
Sr-conduit(S− 1) −0.93 ± 0.41 −1.43 ± 0.51 < 0.001
Sr-booster pump(S−1) − 1.77 ± 0.88 −2.07 ± 0.61 0.104
  1. Abbreviations: S-reservoir RA strain corresponding to reservoir function, S-conduit RA strain corresponding to conduit function, S-booster pump RA strain corresponding to booster pump function, SR-reservoir RA strain rate corresponding to reservoir function, SR-conduit RA strain rate corresponding to conduit function, SR-booster pump RA strain rate corresponding to booster pump function
