Echocardiographic parameters of left ventricular function were measured with LPS treatment (15 mg/kg) with or without CoPPIX (5 mg/kg) and CQ (20 mg/kg) for 3 and 24 h.

<p>Shown are heart-to-body weight ratio (HW/BW), left ventricular end-diastolic diameter (LVDd), left ventricular end-systolic diameter (LVDs), left ventricular fractional shortening (LVFS), and ejection fraction (EF). Each value represents the mean ± S.E. of four animals.</p>**<p><i>p</i><0.01;</p>*<p><i>p</i><0.05 vs. Control.</p>++<p><i>p</i><0.01;</p>+<p><i>p</i><0.05 vs. LPS (24 h).
