Overview
Walk through angina is the appearance of anginal discomfort early in the course of exertion which then subsides despite continuation of exertion.
Walk through angina pectoris
- In the majority of patients with obstructive coronary artery disease, the intensity of angina is associated with the intensity of the physical activity. However, a subset of patients have so called walk through angina.
- These patients experience angina early in the course of physical activity (e.g. walking, gardening, climbing, and short running) but the angina then disappears despite continuation of the activity.
- The precise underlying mechanism of walk though angina remains unclear.
- It has been speculated that this may be due to an initial increase in coronary vascular tone with a consequent reduction in coronary blood flow at the beginning of the exercise.
- It has also been speculated that recruitment of collaterals may also play a role in the phenomenon.
