What health condition is nitroglycerine commonly used to treat?

Nitroglycerine is primarily used to treat angina, which is chest pain caused by reduced blood flow to the heart muscle. When a person experiences angina, it usually occurs during physical exertion or stress, where the heart demands more oxygen than the narrowed arteries can supply. Nitroglycerine works by relaxing the blood vessels, which allows for increased blood flow to the heart and helps to alleviate the pain associated with angina.

By reducing the workload on the heart and dilating the coronary arteries, nitroglycerine effectively relieves symptoms and improves the oxygen supply to the heart muscle. This makes it a critical medication for individuals diagnosed with angina who need immediate relief during episodes of chest pain.

While nitroglycerine may have roles in other cardiovascular conditions, such as heart attacks, its primary and most well-recognized use is in the management of angina. Understanding this context clarifies why it is specifically indicated for treating this particular condition.
