True or False: Angina pectoris is chest pain caused by myocardial ischemia.

Angina pectoris being classified as chest pain caused by myocardial ischemia is indeed true. Myocardial ischemia refers to a reduction in blood flow to the heart muscle, often due to coronary artery narrowing or blockage. When the heart does not receive enough oxygenated blood, it results in discomfort or pain, known as angina. This condition serves as a warning sign of potential heart problems, including the risk of heart attacks. Recognizing that angina is a manifestation of ischemia is critical for addressing and managing underlying cardiovascular disease. Understanding this relationship helps healthcare providers implement early interventions to alleviate symptoms and prevent further cardiac events.
