The purpose of the study is to determine if giving isosorbide,a drug that is used to treat chest pain, affects blood vessel release of an anti-clotting factor.

Study summary:

To test the hypothesis that the administration of the NO donor isosorbide dinitrate,but not the phosphodiesterase inhibitor sildenafil, will attenuate stimulated vascular t-PA release during ACE inhibition whereas both agents will improve glucose uptake.
