The ratio of left ventricle weight to body weight following injection.

Data are presented as means ± standard errors. Sham: control group; Non-BRL: HF group without BRL37344 injection; BRL: HF group with BRL37344 injection; BW: body weight; LVW: left ventricular weight; LV/BW: left ventricular weight/body weight.*P†P‡P§P数据以平均值±标准误（standard error）表示。假手术组（Sham）：对照组；非BRL组（Non-BRL）：未注射BRL37344的心力衰竭（HF）组；BRL组（BRL）：注射BRL37344的心力衰竭（HF）组；体质量（BW，body weight）；左心室质量（LVW，left ventricular weight）；左心室质量/体质量（LV/BW，left ventricular weight/body weight）。*P、†P、‡P、§P
