Angina

Last Updated: July 3, 2026

Key Points

  • Chest pain or tightness, often in other areas like the jaw or arm
  • Caused by reduced blood flow to the heart
  • Often triggered by exercise, stress, or cold temperatures
  • Usually relieved by rest or specific medication
  • Requires medical attention to diagnose and manage

Overview

Angina is a type of chest pain or discomfort that happens when your heart muscle doesn't get enough oxygen-rich blood. It can feel like squeezing, pressure, or a dull ache in your chest, and may spread to your neck, shoulders, jaw, or arms. These episodes are often called angina attacks. The most common cause of angina is coronary heart disease, where the blood vessels supplying your heart become narrowed or blocked by fatty deposits. Less commonly, it can be due to blood vessels in the heart tightening inappropriately. Angina attacks typically last less than 10 minutes and usually stop after resting or taking prescribed medicine. If you experience symptoms of angina, it's important to see a doctor promptly. Managing angina involves medication, lifestyle changes, and sometimes surgical procedures to improve blood flow to the heart. Proper treatment helps reduce symptoms and lower the risk of more serious heart events like a heart attack.
