Diagnostic Tests for Unstable Angina
To diagnose unstable angina, your doctor will perform a combination of physical exams, medical history reviews, and diagnostic tests. Here are some of the tests you may undergo:
Electrocardiogram (ECG or EKG)
An electrocardiogram is a non-invasive test that records the electrical activity of your heart. It can help your doctor identify any abnormalities in your heart’s rhythm or signs of a heart attack.
Blood Tests
Blood tests can help your doctor identify any signs of heart damage or inflammation. These tests may include:
- Troponin test: measures the levels of troponin, a protein released by the heart when it’s damaged
- CK-MB test: measures the levels of creatine kinase, an enzyme released by the heart when it’s damaged
- Complete Blood Count (CBC): measures the levels of white blood cells, red blood cells, and platelets in your blood
Imaging Tests
Imaging tests can help your doctor visualize your heart and coronary arteries. These tests may include:
- Echocardiogram: uses sound waves to create images of your heart
- Stress test: measures your heart’s function and blood flow during physical activity
- Coronary angiogram: uses X-rays and dye to visualize your coronary arteries
Other Diagnostic Tools
In addition to these tests, your doctor may use other diagnostic tools to help identify unstable angina, such as:
- HEART score: a scoring system that evaluates your risk of heart attack or death based on your symptoms, medical history, and test results
- GRACE score: a scoring system that evaluates your risk of heart attack or death based on your symptoms, medical history, and test results
By combining these diagnostic tests and tools, your doctor can accurately diagnose unstable angina and develop an effective treatment plan.
Unstable Angina Treatment Options
Unstable angina is a serious medical condition that requires prompt treatment. The goal of treatment is to reduce your symptoms, prevent heart attacks, and improve your overall quality of life. In this section, we’ll explore the treatment options for unstable angina.
Medications for Unstable Angina
Your doctor may prescribe medications to help manage your symptoms and reduce your risk of heart attack. These medications may include:
