Nitroglycerin is indicated for which condition?

Explanation:
Nitroglycerin works by dilating veins, which lowers venous return (preload) and reduces the heart’s oxygen demand, while also providing some coronary vasodilation to improve blood flow to ischemic areas. This makes it appropriate for chest pain caused by cardiac ischemia (angina). It won’t fix non-cardiac chest pain, hypertension without chest pain, or migraines, because those conditions aren’t driven by the same ischemic process that nitroglycerin targets. So the best indication is chest pain determined to be of cardiac origin.
