Unstable Angina Pectoris

The introduction of intravenously administered nitrate formulations such as intravenous nitroglycerin and intravenous isosorbide dinitrate has markedly improved the conservative therapy of unstable angina. These formulations, originally used only in coronary care units, are now used in general medical wards and emergencies rooms, without hemodynamic monitoring, and in some countries also in mobile coronary care units.
