The present invention relates a number of different lysine containing peptides which can be administered to a mammal to normalize cardiac pressure for treatment of heart disease conditions such as myocardial ischemia. These peptides include certain known peptides, some of which are capable of liberating growth hormone to various degrees when administered to a mammal. Other peptides useful in the invention are novel peptide sequences which include a spirolactam, bicyclic or tricyclic peptidomimetic unit. The peptides disclosed herein exhibit binding to cardiac tissue and normalize cardiac pressure after administration, thus imparting cardiac protecting activity by a mechanism which at the present is unknown. One common feature of the peptides of this invention is that at least one lysine unit is present. |
