Which type of angina is characterized by pain during physical activity or exercise?

Stable angina is characterized by predictable patterns of chest pain or discomfort that occur during physical activity or exercise and is typically relieved by rest or nitroglycerin. This type of angina arises when the heart muscle doesn't get enough oxygen-rich blood during times of increased demand, such as during exertion or stress.

Patients with stable angina usually can anticipate their symptoms based on their activity levels. For instance, if a person commonly experiences chest pain while climbing stairs, they can manage their activities to avoid such situations or stop to rest when feeling symptoms. The key aspect of stable angina is its consistent pattern and timing in relation to physical activity, making it distinct from other forms of angina, which may present differently or unpredictably.
