1. A method of ameliorating at least one cause, symptom or untowards effect of pulmonary hypertension in a subject comprising administering to the subject a therapeutically effective dose of at least one anthracycline selected from the group consisting of daunorubicin, doxorubicin, epirubicin, idarubicin, pyrromycin, aclacinomycin, isorhodomycine and carminomycine, wherein the subject was identified as having pulmonary hypertension prior to administration of the at least one anthracycline.
2. The method of claim 1 , wherein the subject is a mammal.
3. The method of claim 1 , wherein the subject is a human.
4. The method of claim 1 , wherein the at least one anthracycline is daunorubicin or doxorubicin.
5. The method of claim 4 , wherein the anthracycline is daunorubicin and the daunorubicin is administered at a dose of 20 mg/kg or less.
6. The method of claim 5 , wherein the daunorubicin is administered at a dose of 10 mg/kg or less.
7. The method of claim 5 , wherein the daunorubicin is administered at a dose of 5 mg/kg or less.
8. The method of claim 1 , wherein the at least one anthracycline is administered via intravenous injection.
9. The method of claim 1 , wherein the at least one anthracycline is administered as an inhalant.
10. The method of claim 1 further comprising co-administering a therapeutically effective amount of a cardioprotectant to the subject.
11. The method of claim 10 , wherein the cardioprotectant is dexrazoxane.
12. The method of claim 1 further comprising co-administering a therapeutically effective amount of a vasodilator.
13. The method of claim 12 , wherein the vasodilator is selected from the group consisting of Hydralazine, Diazoxide, Minoxidil, Sodium Nitroprusside, Nitroprusside, Diazozide, Ifenprodil Tartrate, Dilazep Dihydrochloride, Cilostazol, Dipyridamole, Isosorbide Dinitrate, Isosorbide Mononitrate, Nitroglycerin, Sildenafil, vardenafil, tadalafil, alprostadil and Papaverine.
14. The method of claim 1 further comprising co-administering a therapeutically effective amount of an iron chelator.
15. The method of claim 14 , wherein the iron chelator is deferoxamine.
16. The method of claim 1 further comprising co-administering a therapeutically effective amount of a p53 inhibitor.
17. The method of claim 16 , wherein the p53 inhibitor is pifithrin-α.
18. The method of claim 17 , wherein the subject has a cardiovascular or pulmonary disease.
