Group C: control animals, Group T (-): taurine-deficient animals; LVSD: left ventricular systolic diameter; BW: body weight; HR: heart rate; CO: cardiac output; % FS: fractional shortening; EF: ejection fraction; E/A: relationship between the E and A waves; IRT: isovolumetric relaxation time; IRTc: isovolumetric relaxation time normalized by the HR. Data are expressed as means ± standard deviations or medians (quartile 1 - quartile 3). Bold values indicate statistical significance (P≤0.05).
