Method of treating cardiac arrhythmia with long acting atrial natriuretic peptide(LA-ANP)
Materials and Methods related to making and using natriuretic polypeptides having a mutation that results in an extended carboxy terminus.
1. A method for treating a cardiac arrhythmia in a mammal in need thereof, comprising administering to the mammal an effective amount of a polypeptide comprising the amino acid sequence set forth in SEQ ID NO:6, with two amino acid additions, subtractions, or substitutions, wherein the polypeptide has a length between 17 and 45 amino acids and has natriuretic activity.
2. A method for treating a cardiac arrhythmia in a mammal in need thereof, comprising administering to the mammal an effective amount of a polypeptide comprising the amino acid sequence set forth in SEQ ID NO:6, with one amino acid addition, subtraction, or substitution, wherein the polypeptide has a length between 17 and 45 amino acids and has natriuretic activity.
