Overview
Angina happens when the heart muscle doesn't get enough oxygen-rich blood during exertion. It often feels like pressure, squeezing, heaviness, or tightness in the chest, and may spread to the arm, neck, jaw, or back. It usually goes away within a few minutes of rest.
Women, older adults, and people with diabetes may feel shortness of breath, tiredness, or nausea instead. Angina that's new, happens more often, comes with less activity, or happens at rest (unstable angina) is an emergency because a heart attack may be coming.
When to get medical care
Causes
Most angina is caused by coronary artery disease from plaque buildup. Risk factors include high blood pressure, high cholesterol, diabetes, smoking, obesity, inactivity, older age, and family history. Other causes include aortic stenosis, thickened heart muscle, severe anemia, and coronary artery spasm.
OwieClear has pages on 2 conditions that can cause chest pressure with activity that goes away with rest. Each shows how soon to get care.
Common causes
- Angina (chest pain from narrowed heart arteries)Often needs care today
Chest pressure, squeezing, or tightness that comes on with activity or stress and eases with rest.
- Coronary spasm and small-vessel heart diseaseOften needs care today
Chest pain from heart arteries that suddenly tighten (spasm), often at night or early morning, or from disease in the tiny heart vessels.
What you can do at home
- Stop and rest when chest pressure starts.
- Use nitroglycerin as prescribed; if pain isn't better 5 minutes after the first dose, call 911.

- Eat a heart-healthy diet.
- Exercise as your provider advises, often in cardiac rehab.
