Methods for reducing morality associated with acute myocardial infarction
Methods of reducing mortality in myocardial infarction patients receiving a stent in connection with percutaneous transluminal coronary angioplasty include administering an anti-inflammatory compound to the patient. In one embodiment, the anti-inflammatory compound is an antibody to a complement component.
1. A method of treating acute myocardial infarction comprising:
administering a mortality reducing amount of an anti-C5 antibody to a subject receiving a stent in connection with percutaneous transluminal coronary angioplasty.
2. The method as in claim 1 wherein the antibody is h5G1.1-scFv.
3. The method as in claim 1 wherein the antibody is an antibody that directly or indirectly reduces the conversion of complement component C5 into complement components C5a and C5b.
4. The method as in claim 3 wherein the antibody is an antibody comprising at least one antibody-antigen binding site, said antibody exhibiting specific binding to human complement component C5, said specific binding being targeted to the alpha chain of human complement component C5, wherein the antibody 1) inhibits complement activation in a human body fluid; 2) inhibits the binding of purified human complement component C5 to either human complement component C3 or human complement component C4; and 3) does not specifically bind to the human complement activation product for C5a.
5. A method of reducing mortality in a subject with acute myocardial infarction receiving a stent in connection with percutaneous transluminal coronary angioplasty comprising:
administering to the subject a first dose of an anti-C5 antibody prior to performing the percutaneous transluminal coronary angioplasty; and
subsequently administering a second dose of the anti-C5 antibody by intravenously infusing the subject over a period of at least 4 hours.
6. The method as in claim 5 wherein the second dose is administered no later than 4 hours after the first dose.
7. The method as in claim 5 wherein the second dose is administered over a period of 8 to 24 hours.
8. The method as in claim 5 wherein the second dose is administered over a period of 12 to 20 hours.
9. The method as in claim 5 wherein the antibody is h5G1.1-scFv.
10. The method as in claim 5 wherein the antibody is an antibody that directly or indirectly reduces the conversion of complement component C5 into complement components C5a and C5b.
11. The method as in claim 10 wherein the antibody is an antibody comprising at least one antibody-antigen binding site, said antibody exhibiting specific binding to human complement component C5, said specific binding being targeted to the alpha chain of human complement component C5, wherein the antibody 1) inhibits complement activation in a human body fluid; 2) inhibits the binding of purified human complement component C5 to either human complement component C3 or human complement component C4; and 3) does not specifically bind to the human complement activation product for C5a.
12. A method of reducing mortality in a subject with acute myocardial infarction receiving a stent in connection with percutaneous transluminal coronary angioplasty comprising administering an anti-C5 antibody to the subject.
13. The method as in claim 12 wherein the antibody is h5G1.1-scFv.
14. The method as in claim 12 wherein the antibody an antibody that directly or indirectly reduces the conversion of complement component C5 into complement components C5a and C5b.
15. The method as in claim 14 wherein the antibody is an antibody comprising at least one antibody-antigen binding site, said antibody exhibiting specific binding to human complement component C5, said specific binding being targeted to the alpha chain of human complement component C5, wherein the antibody 1) inhibits complement activation in a human body fluid; 2) inhibits the binding of purified human complement component C5 to either human complement component C3 or human complement component C4; and 3) does not specifically bind to the human complement activation product for C5a.
16. The method as in claim 12 wherein the antibody is administered as a first dose prior to performing the percutaneous transluminal coronary angioplasty; and a second dose of the antibody is subsequently administered by intravenously infusing the subject over a period of at least 4 hours.
17. The method as in claim 16 wherein the second dose is administered no later than 4 hours after the first dose.
18. The method as in claim 16 wherein the second dose is administered over a period of 8 to 24 hours.
19. The method as in claim 16 wherein the second dose is administered over a period of 12 to 20 hours.
20. A method of treating acute myocardial infarction comprising:
administering a stent in connection with percutaneous transluminal coronary angioplasty, the stent comprising a coating that contains an anti-C5 antibody.
21. The method as in claim 20 wherein the antibody is h5G1.1-scFv.
22. The method as in claim 20 wherein the antibody is an antibody that directly or indirectly reduces the conversion of complement component C5 into complement components C5a and C5b.
23. The method as in claim 22 wherein the antibody comprising at least one antibody-antigen binding site, said antibody exhibiting specific binding to human complement component C5, said specific binding being targeted to the alpha chain of human complement component C5, wherein the antibody 1) inhibits complement activation in a human body fluid; 2) inhibits the binding of purified human complement component C5 to either human complement component C3 or human complement component C4; and 3) does not specifically bind to the human complement activation product for C5a.
