The animals with heart failure were divided into two groups, one with CHF and one with compensated heart failure, based on determinations of LVEDP (see Table 1 and Methods). Heart failure-all represent all animals that were subjected to left coronary artery ligation 4 weeks earlier—i.e., the two groups combined. Values are expressed as mean ± SE. 

^*P < 0.05 when group was compared to sham. 

^†P < 0.05 when compared to the group with compensated heart failure.
