Nitroglycerin is indicated for the treatment of which two conditions?

Nitroglycerin is commonly used in the treatment of heart-related conditions due to its vasodilating properties, which help to alleviate chest pain and improve blood flow. It is particularly effective in managing angina, which is a type of chest pain caused by reduced blood flow to the heart muscle. By dilating blood vessels, nitroglycerin helps to decrease the heart's workload and increases the oxygen supply to the heart, relieving the pain associated with angina.

Additionally, nitroglycerin is indicated for use during a heart attack, also known as myocardial infarction. In this scenario, it can help to relieve chest pain and improve blood flow to the heart, potentially limiting damage to the heart muscle and aiding in recovery.

Other choices mention conditions like muscle spasms, hypertension, and stroke, which are not primary indications for nitroglycerin. While managing hypertension may involve other medications and treatment strategies, nitroglycerin is not specifically indicated for this. Stroke management also involves different therapeutic approaches and interventions. Therefore, the correct pairing of heart attack and angina truly reflects the therapeutic uses of nitroglycerin.
