Post-stent chest pain

by Carolyn Thomas     @HeartSisters 

A friend’s daughter (who happens to be a cardiac nurse) phoned to check on me a few days after I was discharged from the hospital following my heart attack. I felt so relieved to hear Kate’s voice because  something was really starting to worry me:  I was still having chest pain.

Hadn’t the blocked coronary artery that had caused my “widow maker” heart attack just recently been magically unblocked? Wasn’t that newly revascularized artery now propped wide open with a shiny metal stent? Shouldn’t I be feeling better?

And that’s when I heard the words “stretch pain”  for the first time.    .       . 

She explained to me exactly what I would later learn more about from cardiac researchers in Germany: moststretch pain” symptoms are due to the dilation and stretching of a coronary artery that’s caused when a coronary stent is being implanted inside that artery.(1)  And for the majority of heart patients, she added, stretch pain is not a danger sign.

But if you’re like me, you may still be concerned, after your stent has been newly implanted, to find that the chest pain that sent you to the hospital in the first place is still happening.

At the time, I could find no information about chest pain AFTER a stent procedure in any of the patient education material I was given before I was discharged from the CCU (the Intensive Care Unit for heart patients).

But now I was learning that this new chest pain might be BECAUSE of a stent procedure.

The German researchers agreed that post-stent chest pain is likely not a reason for us to panic. But they did acknowledge:

“This is a common problem. Although the development of chest pain after coronary interventions may be benign, it is disturbing to patients, relatives and hospital staff.”

Disturbing? No kidding. . . 

New chest pain is very disturbing to a person who has just survived a heart attack.

In the German study, researchers found that stretch pain can be experienced after different types of cardiac interventions:

  • about 40 per cent of the patients they studied developed chest pain after having a coronary stent implanted (Percutaneous Coronary Intervention, or PCI)
  • 12 per cent developed chest pain after balloon angioplasty
  • 9 per cent developed chest pain after diagnostic angiography

As cardiologist Dr. Allen Jeremias explained in his book, Your Personal Guide to Angioplasty:

“The air pressure in your fully inflated car tires is about 2 atmospheres. By comparison, the high pressure used to inflate a balloon inside a coronary artery during angioplasty is between 10-20 atmospheres.”

Researchers suggest that chest pain in recently stented patients can be associated with continuous stretching of the treated coronary artery during an invasive procedure, which they described like this in the journal, Circulation:(2)

“Non-ischemic chest pain develops in almost half of all patients undergoing stent implantation, and seems to be related to blood vessel over-expansion caused by the stent inside the diseased vessel.”

U.K. sources add that it’s common to experience this new chest discomfort in the first few days and weeks following a stent procedure.

“This is because your artery has suffered some trauma and bruising from the stent being fitted. You can have episodes of pain or discomfort as the stent settles into place. This pain is usually felt quite locally in the chest, and is often described as sharp or stabbing. This type of pain can often be relieved by taking acetaminophen (Tylenol).”

Symptoms have been generally described by patients as mild or moderate, and also “unlike the pain of angina” that they had experienced before they came into the hospital for treatment. Three-quarters of patients with this pain described it as “continuous, squeezing pain located deep in the chest.” 

What if stretch pain continues or gets worse?

Stretch pain is typically a short-term issue while we are recuperating.  But sometimes, it is not just short-term.

The Journal of the American Heart Association reported that about one third of heart attack patients studied were still reporting occasional chest pain at six weeks or longer.(3)  These symptoms happened infrequently – about 80 per cent experienced symptoms once a month on average, but of the remaining 20 per cent, chest pain was happening weekly or even daily.

This kind of chest pain may not be just your average stretch pain.

If chest pain persists or worsens over weeks, it may indicate another cardiac issue that must be checked out. In a 2018 U.K. study, researchers turned the cardiology world on its ear by suggesting that stents may not address chest pain as we have always believed – especially for patients who have not had a heart attack.(4)  Coronary artery disease (CAD) typically affects many blood vessels, and so stenting only the largest blockage may not make much difference in a patient’s symptoms. As the New York Times described the findings of this study:

A few arteries might be blocked today, and then reopened with stents. But tomorrow a blockage might arise in another artery, and cause a heart attack.”

Always consult your own physician for ongoing or new chest pain, or any distressing symptoms that simply do not feel right to you.  See also: ISCHEMIA Study: That Blockage Isn’t A Time Bomb In Your Chest (about the controversial 2019 research that found stents or bypass surgery are no more effective – except during a heart attack – than providing optimal medical therapy; as I noted at the time, however, fewer than 1/4 of the ISCHEMIA study participants were women).

But meanwhile, my own question on stretch pain is still this: 

“If stretch pain caused by having a stent implanted is as common as cardiac researchers seem to suggest, why aren’t heart patients like me warned about this before hospital discharge so we don’t need to panic during recovery?”

Q:  Have you ever experienced stretch pain after a cardiac procedure?


Please do not leave a comment here asking me about your current symptoms. I  am not a physician and cannot offer you medical advice. Always see a healthcare professional if you’re experiencing distressing symptoms.

  1. Well it’s Thanksgiving day, and I had 4 stents implanted on Monday afternoon, 3 days ago, and 2 implanted in 2015. NO ONE EVER TOLD ME ABOUT STRETCH PAIN!

    SO RELIEVED TO HEAR ABOUT THIS 🤗 because I feel the chest pain just walking to the bathroom. Actually I was in pain during my procedure and in the recovery room, I was crying it hurt so bad. I was told the Dr. had to do a lot of work, such as breaking up the plaque…and I had to work through the chest pain. I thought you have to be kidding me, they gave me more Nitro and Tylenol for the headache I was bound to get from the effects of the medication.

    So anyway here I sit, 3 days later, no pain thank god, while sitting, hoping, praying I can change my lifestyle habits and start a better way of living free of chest pain in the years to come. I will keep you updated.

    Thank you so much for the article, it has given me MUCH HOPE !!!
    by the way I just turned 56 on the 11th of November 🦃 Happy Thanksgiving everyone.

    1. Hello Kelly – I’m glad you found my site! You’re not alone – if you read some of the comments below, you’ll see many many others who say “NO ONE EVER TOLD ME ABOUT STRETCH PAIN!” Given how common researchers tell us that this post-stent chest pain is, it’s hard to believe that so many healthcare professionals working in cardiology do not know this. Yet every person like you or me who do experience this, and learn more about it, are helping to spread the word to others, in the hope that one day nobody will be unaware of this very common after-effect of having a stent implanted, because the likelihood will routinely be explained before hospital discharge.

      Hope you continue to feel better – good luck with your decision to change some habits! You can do it!!

      Take care, stay safe. . . ♥


  2. I was so relieved when a friend found this article and sent it to me.

    I am 6 days since my heart attack and 4 days after having two stents put in my artery. The whole time I complained in the hospital to all medical staff, doctors and nurses about the continuing sharp jabbing pain I was still having in my chest, specifically my heart.

    They would just tell me, “But your numbers look good”. I didn’t want to hear that my pain continued and I had been told I had a widow maker artery that was 45 percent blocked but they only do stents in arteries that are 70 percent blocked. I just knew my pain has been leading up to the
    “big” heart attack.

    I feel relieved reading this article and promptly send messages to both my doctors so perhaps they could learn something new from it too. I am very grateful to the author and every comment.
    Thank you!

    1. Hello Angie – I’m glad your friend forwarded this article to you. The thing that makes stretch pain really annoying is that research suggests it’s VERY COMMON – yet so few physicians or nurses seem to be aware of it as a potential culprit when hearing reports of ongoing post-stent chest pain. Many heart patients worry needlessly for weeks after hospital discharge, believing that another heart attack is imminent, all because nobody warned them how common this post-stent symptom actually is.

      You are still in very early days yet – I hope that your sharp jabbing pain will ease up as healing continues over time. If it doesn’t, or if it gets worse, see your doctor. Good luck to you…

      Take care, stay safe… ♥


  3. Hi again Carolyn,

    My post-stent stretching pain lasted exactly 3 months. My Cardiac rehab nurse didn’t give it much credence.

    Not only that, I received a call after 3 weeks (instead of weekly check-in) while I was brushing my teeth. When I called back I couldn’t get through to the nurse, left a message, no call-back.

    Best part: in my post-review report, she stated exactly that patient brushing teeth, will call back. I am wondering if this was a joke or does someone actually care, is paying attention to the patient, or just checking a box ‘done’……

    1. Hi again Romi – I’ve run across some medical studies that were so obscure that “patient brushing teeth” might actually have been something they’d record! 🙂

      Just imagine: a research paper on how often a heart patient is busy brushing her teeth when a nurse phones.

      Sounds like a tickbox needing checking off to me. . .

      Take care, stay safe. . . ♥
