A positive exercise stress test in a patient with recurrent angina indicates the presence of ischemia. During the test, the patient exercises, typically on a treadmill or stationary bike, and the response of the heart is monitored. If the test results in a decrease in blood flow to the heart muscle, which can be observed as ST segment changes on an electrocardiogram (ECG) or through reports of angina symptoms, this suggests that the heart is not receiving adequate oxygen compared to its demand during physical exertion.

This indicates underlying coronary artery disease or other issues that may restrict blood flow. The identification of ischemia during stress is significant as it helps clinicians understand the severity of the patient’s condition and can guide treatment decisions, such as the necessity for more invasive testing, modifications in medication, or surgical interventions.

The other options do not align with the diagnostic purpose of a positive exercise stress test in the context of recurring angina. A balanced oxygen demand and supply would not warrant a positive test, while normal vital signs would typically indicate that the heart is responding adequately to stress. Cardiac arrhythmias, while they can be noted during an exercise test, are not the primary indication of ischemia and do not specifically correlate with the recurring chest
