From: Myocardial ultrasonic tissue characterization in patients with thyroid dysfunction

  Hyperthyroidism
(n = 10)
Hypothyroidism
(n = 6)
Subclinical Hypothyroidism
(n = 8)
  Baseline Treatment Baseline Treatment Baseline Treatment
CC of IBS 1.7 ± 0.7 1.3 ± 0.2 b 1.6 ± 0.2 1.4 ± 0.3 1.4 ± 0.2 1.4 ± 0.2
CV (dB) 8.1 ± 2.1 11.1 ± 4.7 8.3 ± 2.0 12.3 ± 2.9 a 8.2 ± 2.7 10.9 ± 4.3
CVI (%) 39.1 ± 11.5 41.5 ± 14.2 41.2 ± 19.6 51.8 ± 16.2 36.1 ± 20.4 52.3 ± 18.4
  1. a = p < 0.05; b = p < 0.08 vs baseline; CC of IBS = correct coefficient of IBS; CV = absolute cyclic variation of IBS; CVI = percentual relationship between CV and mean value of IBS
