What causes persistent chest pain after undergoing CABG?

Hello,

Welcome to icliniq.com.

I understand your concern.

You are a 51-year-old man who underwent CABG (coronary artery bypass grafting) eight months ago and are still experiencing chest pain, pain behind the shoulder, and dizziness. These symptoms are not expected to persist this long without a clear underlying cause, and they warrant a thorough medical evaluation.

Possible causes of your current symptoms:

A. Cardiac-related causes (most important to rule out):

1. Graft failure or recurrent blockage.
2. Angina due to narrowing in other coronary arteries.
3. Pericarditis (inflammation around the heart, which can cause chest and shoulder pain).
4. Low blood pressure, which may lead to dizziness.

B. Non-cardiac causes:

1. Musculoskeletal pain related to sternotomy or poor posture after surgery.
2. Nerve damage or irritation.
3. Anxiety or post-CABG depression (these can mimic or worsen physical symptoms).
4. Vestibular disorders or medication side effects (dizziness from beta-blockers or antihypertensives).

Recommended tests may include:

1. ECG (electrocardiogram).
2. Echocardiogram.
3. Stress test or CT (computed tomography) coronary angiogram.
4. A Holter monitor, if dizziness might be related to the heart rhythm.

What you should do now:

1. Consult a cardiologist as soon as possible, these symptoms should not be ignored, especially the combination of chest and shoulder pain with dizziness.

Review your medications:

1. Some medications prescribed after CABG (like beta-blockers or nitrates) may cause dizziness.
2. Pain might also be muscular or neuropathic, requiring specific treatment.

Lifestyle review:

1. Are you walking or exercising regularly?
2. Are your blood pressure, cholesterol, and blood sugar under control?
3. Any history of smoking or alcohol use?

When to go to the hospital:

1. If chest pain feels sharp, heavy, or pressure-like, especially during activity.
2. If you experience shortness of breath, sweating, or palpitations.
3. If dizziness leads to fainting or loss of balance.

I hope this explanation is helpful.
