Unstable Angina Diagnosis & Tests
-
Physical examination may reveal a change in blood pressure. Transient heart murmur or arrhythmias (irregular heartbeats) may occur as well.
-
ECG changes that occur at rest, during pain, are often diagnostic.
- Heart scans or coronary angiography of the heart are often performed.
- Echocardiography may reveal changes in the heart caused by decreased coronary blood flow.
- Blood tests such as CPK, CPK-MB, troponin I, troponin T, and myoglobin are used to diagnose unstable angina and can predict likelihood of progression to heart attack.
