Angina pectoris is characterized by chest pain or discomfort due to reduced blood flow to the heart muscle, typically associated with stress, physical exertion, or underlying heart conditions. The primary method for alleviating symptoms of angina is the use of nitroglycerin. This medication works by dilating blood vessels, which improves blood flow to the heart muscle, thus relieving the pain associated with angina attacks.

When administered, nitroglycerin can quickly relieve symptoms by reducing the heart's workload and increasing oxygen delivery to the heart. It is important for patients with a history of angina to have this medication on hand, as it can provide fast relief during an episode.

Other options, such as sitting in a cold room or drinking several glasses of water, do not directly address the underlying issue of inadequate blood flow to the heart muscle and are not effective in alleviating angina symptoms. While contacting emergency services may be necessary if the symptoms are severe or persistent, nitroglycerin remains the recommended immediate treatment for an angina episode.
