Delayed, second window RIC improves post-ischemic cardiac performance in isolated perfused hearts.

Representative LVDP (A) and LVEDP (B) tracings are shown from 2W control and RIC groups. Left ventricular developed pressure (LVDP) is expressed as a percentage of pre-ischemic baseline values and left ventricular end diastolic pressure (LVEDP) is expressed in mm Hg. Values are expressed as means ± S.E.M. An (*) denotes a statistically significant difference (P<0.05) compared to control groups after 60 minutes of reperfusion.
