Abstract

This invention pertains to methods and compositions for the diagnosis and treatment of cardiovascular conditions. More specifically, the invention relates to isolated molecules that can be used to diagnose and/or treat cardiovascular conditions including cardiac hypertrophy, myocardial infarction, stroke, arteriosclerosis, and heart failure.

Claims

1. A method for predicting outcome of a cardiovascular condition in a subject having or suspected of having a cardiovascular condition and treating the subject, the method comprising:

(a) performing an assay to determine a level of soluble ST2 in a sample from a subject having or suspected of having a cardiovascular condition;

(b) comparing the level of soluble ST2 in the sample to a predetermined value specific for predicting outcome of the cardiovascular condition;

(c) identifying a subject having an elevated level of soluble ST2 compared to the predetermined value as having an increased likelihood of a negative outcome of a cardiovascular condition as compared to a subject not having an elevated level of soluble ST2 compared to the predetermined value; and

(d) administering an agent for reducing the risk of a cardiovascular condition to the subject identified in (c).

2. The method of claim 1, wherein the cardiovascular condition is selected from the group consisting of:

cardiac hypertrophy, myocardial infarction, stroke, and heart failure.

3. The method of claim 1, wherein the negative outcome is death, development of congestive heart failure, or worsening congestive heart failure.

4. The method of claim 3, wherein the death is in-hospital death or death within 30 days.

5. The method of claim 1, wherein the subject has an episode of ischemic discomfort.

6. The method of claim 5, further comprising obtaining a sample from the subject, wherein the sample is obtained from the subject within 12 hours of the episode of ischemic discomfort or 1, 3, 12, or 24 hours after the episode of ischemic discomfort.

7. The method of claim 5, further comprising obtaining a sample from the subject, wherein the sample is obtained from the subject within 6 hours of the episode of ischemic discomfort.

8. The method of claim 1, further comprising determining the level of at least one other marker related to the cardiovascular condition.

9. The method of claim 8, wherein the at least one other marker is selected from the group consisting of:

a circulating catecholamine, angiotensin II, creatinine, creatine kinase MB isoenzyme, C-reactive protein, a troponin, a natriuretic peptide, and a marker of oxidative stress.

10. The method of claim 9, wherein the at least one other marker is a troponin or a brain natriuretic peptide.

11. The method of claim 9, wherein the troponin is cardiac troponin I.

12. The method of claim 9, wherein the circulating catecholamine is norephinephrine, dopamine, or epinephrine.

13. The method of claim 9, wherein the natriuretic peptide is a brain natriuretic peptide (BNP) or pro-atrial natriuretic peptide (ProANP).

14. The method of claim 13, wherein the natriuretic peptide is a BNP.

15. The method of claim 9, wherein the marker of oxidative stress is adrenolutin or malondialdehyde.

16. The method of claim 1, wherein the sample comprises a biological fluid.

17. The method of claim 16, wherein the biological fluid is blood or serum.

18. The method of claim 1, wherein the subject is without ischemic disease.

19. The method of claim 1, wherein the agent is selected from the group consisting of:

an anti-inflammatory agent, an anti-thrombotic agent, an anti-platelet agent, a fibrinolytic agent, a lipid-reducing agent, a direct thrombin inhibitor, a glycoprotein IIb/IIIa receptor inhibitor, a calcium channel blocker, a beta-adrenergic receptor blocker, a cyclooxygenase-2 inhibitor, and a renin-angiotensin system (RAS) inhibitor.

20. The method of claim 19, wherein the renin-angiotensin system inhibitor is selected from the group consisting of:

an angiotensin-converting enzyme (ACE) inhibitor, an angiotensin II receptor blocker (ARB), an angiotensin II receptor antagonist, an agent that activates the catabolism of angiotensin II, and an agent that prevents the synthesis of angiotensin I.

21. The method of claim 1, wherein the assay in (a) is performed using an antibody that specifically binds to soluble ST2.

22. A method for predicting outcome of a cardiovascular condition in a subject having or suspected of having a cardiovascular condition and treating the subject, the method comprising:

(a) performing an assay to determine a first level of soluble ST2 in a sample obtained at a first time point from a subject having or suspected of having a cardiovascular condition;

(b) performing an assay to determine a second level of soluble ST2 in a sample obtained at a second time point from the subject;

(c) comparing the second level of soluble ST2 to the first level of soluble ST2;

(d) identifying a subject having an elevated second level of soluble ST2 compared to the first level of soluble ST2 as having an increased likelihood of a negative outcome of a cardiovascular condition as compared to a subject not having an elevated second level of soluble ST2 compared to the first level of soluble ST2; and

(d) administering an agent for reducing the risk of a cardiovascular condition to the subject identified in (c).

23. The method of claim 22, wherein the cardiovascular condition is selected from the group consisting of:

28. The method of claim 22, further comprising determining the level of at least one other marker related to the cardiovascular condition.

29. The method of claim 28, wherein the at least one other marker is selected from the group consisting of:
