Question 1

What is Unstable Angina?

Accepted Answer

Unstable angina is a serious cardiovascular condition characterized by unpredictable chest pain or discomfort that occurs at rest or with minimal exertion. It is caused by reduced blood flow to the heart muscle due to partial blockage or spasm of the coronary arteries, often from atherosclerotic plaque buildup. The Troponin T High Sensitivity test is the most important test for distinguishing unstable angina from heart attack and assessing the severity of cardiac damage.

Question 2

What causes unstable angina?

Accepted Answer

Unstable angina is caused by reduced blood flow to the heart muscle due to partial blockage or spasm of the coronary arteries. Atherosclerotic plaque buildup narrows the coronary arteries, and when these plaques rupture or develop blood clots, they can suddenly restrict blood flow. Unlike stable angina which occurs predictably with exertion, unstable angina happens unpredictably at rest or with minimal activity, making it a medical emergency requiring immediate evaluation.

Question 3

What is the best test for unstable angina?

Accepted Answer

The Troponin T High Sensitivity test is the most important blood test for unstable angina because it detects troponin T, a protein released when heart muscle is damaged. While unstable angina typically doesn't cause significant troponin elevation, slight increases may occur due to temporary coronary artery blockage, helping doctors distinguish unstable angina from a full heart attack. This test is essential for determining the severity of your condition and guiding treatment decisions, and should be interpreted alongside an electrocardiogram and clinical evaluation.

Question 4

When should I get tested for unstable angina?

Accepted Answer

You should get tested immediately if you experience chest pain or discomfort that occurs at rest, worsens in frequency or intensity, lasts longer than usual, or isn't relieved by rest or nitroglycerin. Seek emergency care if you have new chest pain that feels like pressure, squeezing, or heaviness in the chest, especially if accompanied by shortness of breath, nausea, sweating, or pain radiating to your arm, jaw, or back. Unstable angina is a medical emergency that requires urgent evaluation to prevent a heart attack.

Question 5

What are the symptoms of unstable angina?

Accepted Answer

Unstable angina symptoms include chest pain or discomfort that feels like pressure, squeezing, heaviness, or tightness in the chest. You might notice the pain occurring at rest or waking you from sleep, lasting longer than 10-15 minutes, or not improving with rest or medication that previously helped. The discomfort may radiate to your shoulders, arms, neck, jaw, or back, and can be accompanied by shortness of breath, sweating, nausea, lightheadedness, or extreme fatigue.

Question 6

Who is at risk for unstable angina?

Accepted Answer

People with existing coronary artery disease, previous heart attacks, or a history of stable angina are at highest risk for unstable angina. Risk increases with age, smoking, high blood pressure, high cholesterol, diabetes, obesity, physical inactivity, and a family history of heart disease. Men over 45 and women over 55 have increased risk, as do people with high stress levels or chronic kidney disease. Having multiple risk factors significantly increases your likelihood of developing unstable angina.

Question 7

What happens if unstable angina is left untreated?

Accepted Answer

Untreated unstable angina can progress to a full heart attack, causing permanent damage to heart muscle tissue and potentially leading to heart failure or sudden cardiac death. The partially blocked coronary arteries may become completely blocked, cutting off blood supply to portions of the heart. This is why unstable angina is considered a medical emergency requiring immediate hospitalization and treatment. Early intervention with medications and possibly procedures like angioplasty or stenting can prevent these serious complications and save your life.

Question 8

Can unstable angina be diagnosed with a blood test?

Accepted Answer

Unstable angina cannot be diagnosed by blood tests alone, but the Troponin T High Sensitivity test is crucial for evaluation and distinguishing it from a heart attack. While unstable angina typically shows normal or minimally elevated troponin levels, a heart attack shows significantly elevated levels. Diagnosis requires a combination of your symptoms, medical history, electrocardiogram findings, and blood test results. Your doctor may also order additional tests like stress tests or cardiac catheterization to visualize coronary artery blockages.

Question 9

How is unstable angina treated?

Accepted Answer

Unstable angina requires immediate hospitalization and aggressive treatment to restore blood flow and prevent a heart attack. Treatment typically includes medications like aspirin, blood thinners, beta-blockers, nitroglycerin, and statins to reduce blood clots and improve blood flow. Many patients undergo cardiac catheterization to identify blockages, followed by angioplasty with stent placement to open narrowed arteries. In severe cases, coronary artery bypass surgery may be necessary. Long-term management includes lifestyle changes and medications to prevent future episodes.

Question 10

How can I prevent unstable angina?

Accepted Answer

You can reduce your risk of unstable angina by managing cardiovascular risk factors through lifestyle changes and medical care. Quit smoking, maintain a healthy weight, exercise regularly with your doctor's approval, and eat a heart-healthy diet low in saturated fats and high in fruits, vegetables, and whole grains. Control high blood pressure, high cholesterol, and diabetes through medication and lifestyle modifications. Take prescribed heart medications as directed, manage stress through relaxation techniques, and attend regular check-ups to monitor your heart health.

Question 11

What can I do at home for unstable angina?

Accepted Answer

While unstable angina requires emergency medical treatment, once stabilized you can support heart health at home by taking all prescribed medications exactly as directed and keeping nitroglycerin accessible. Rest when you feel chest discomfort and avoid triggers like heavy meals, cold weather, or emotional stress. Monitor your symptoms carefully and call 911 immediately if chest pain worsens or doesn't respond to medication. Follow a heart-healthy diet, limit salt and caffeine, and gradually increase activity as approved by your cardiologist. Never attempt to treat unstable angina symptoms at home without medical evaluation.
