Introduction
If you or a loved one has recently undergone angioplasty, you might be concerned about post-procedure symptoms like fever. It’s natural to worry, but understanding what’s normal and when to seek help can ease your mind. Let’s explore whether fever is common after angioplasty, its possible causes, and when you should consult a doctor.
Understanding Angioplasty
Angioplasty is a minimally invasive procedure used to open blocked or narrowed coronary arteries (the blood vessels supplying the heart). A tiny balloon is inflated inside the artery to widen it, and often a stent (a small mesh tube) is placed to keep the artery open. While angioplasty is generally safe, like any medical procedure, it can have some side effects.
Is Fever Normal After Angioplasty?
A mild fever (below 100.4°F or 38°C) in the first 24-48 hours after angioplasty can sometimes occur and may not always be a cause for concern. This could be due to:
1. Body’s Response to the Procedure: The body may react to the stent placement or catheter insertion with a slight temperature rise.
2. Contrast Dye Reaction: The dye used during angioplasty can sometimes cause a mild fever.
3. Minor Inflammation: The procedure can cause temporary inflammation in the treated artery, leading to a low-grade fever.
However, if the fever is high (above 100.4°F or 38°C), persistent, or accompanied by other symptoms, it could indicate an infection or another complication that needs medical attention.
When Should You Be Concerned?
Seek immediate medical help if you experience:
High fever (above 101°F or 38.3°C)
Chills or sweating
Increased pain, redness, or swelling at the catheter insertion site, usually the groin or wrist
Shortness of breath or chest discomfort
Unusual fatigue or dizziness

These could be signs of an infection, stent-related issues, or other complications that require prompt treatment.
Possible Causes of Fever After Angioplasty
Here are some possible causes of fever after angioplasty, and understanding them can help you know when it’s a normal part of recovery and when to seek medical attention:
1. Infection: Though rare, infections can occur at the catheter insertion site or inside the artery.
2. Stent Reaction: Some people may develop a mild inflammatory response to the stent.
3. Contrast-Induced Reaction: The dye used in the procedure can sometimes cause a reaction, including fever.
4. Blood Clot or Thrombosis: A clot near the stent can sometimes trigger fever along with other symptoms.
How to Manage Mild Fever at Home?
If you have a low-grade fever without severe symptoms, you can:
Stay hydrated: Drink plenty of water to help your body recover.
Rest: Avoid strenuous activities for a few days.
Take prescribed medications: Your doctor may recommend paracetamol (acetaminophen) for fever. Avoid aspirin or ibuprofen unless advised.
Monitor your temperature: Check regularly and note any changes.
Preventing Complications After Angioplasty
To reduce the risk of fever or infections:
Keep the insertion site clean and dry: Follow your doctor’s instructions on wound care.
Take prescribed antibiotics (if given): Some patients may need preventive antibiotics.
Avoid heavy lifting or excessive movement: This helps prevent bleeding or irritation at the catheter site.
Follow up with your doctor: Attend all post-procedure check-ups.
When to Consult a Doctor?
If your fever:
Does not go away in 1-2 days
Gets worse or spikes suddenly
Is accompanied by other worrying symptoms like chest pain, swelling, or discharge at the insertion site
Don’t hesitate to contact your healthcare provider or visit the nearest hospital. Early intervention can prevent serious complications.
Conclusion
A mild fever after angioplasty can be normal, but it’s important to stay vigilant. Most fevers subside within a day or two, but if you’re unsure or concerned, always check with your doctor. Your health and peace of mind matter!
