Adverse transverse-tubule remodeling in a rat model of heart failure is attenuated with low-dose triiodothyronine treatment

Table 3 Cardiomyocyte calcium transient measurements (rise and fall)

	Sham	MI + Veh	MI + T3
Ca²⁺ Rise (Max Rate/Peak Ca²⁺ Height)	67.1 ± 4.1	72.2 ± 7.3	67.0 ± 9.8
Time at max rate of Ca²⁺ Rise (s)	0.016 ± 0.002	0.017 ± 0.003	0.015 ± 0.002
Ca²⁺ Fall (Max Rate/Peak Ca²⁺ Height)	4.84 ± 0.25	4.83 ± 0.24	5.38 ± 0.61
Time at max rate of Ca²⁺ Fall (s)	0.175 ± 0.001	0.183 ± 0.008	0.171 ± 0.016
Area Under Curve of Ca²⁺ Fall Phase	0.068 ± 0.013	0.072 ± 0.019	0.050 ± 0.014

Values are mean ± SD. MI, myocardial infarction; Veh, vehicle; T3, triiodothyronine. Sham, n = 5; MI + Veh, n = 7, MI + T3, n = 5; Max Rate is max velocity of Ca²⁺ rise (release) or Ca²⁺ fall (re-uptake) phase of the transient
