Overview
Walk through angina is the appearance of anginal chest discomfort early in the course of exertion which subsequently subsides despite continued exertion.
Pathophysiology
- The precise underlying mechanism of walk though angina remains unclear.
- It has been speculated that walk through angina may be due to an initial increase in coronary vascular tone with a consequent reduction in coronary blood flow at the beginning of exercise.
- It has also been speculated that recruitment of collaterals may also play a role in the walk through angina phenomenon.
Diagnosis
Symptoms
- 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 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.
Treatment
The treatment is the same as chronic stable angina.
