Not every heart surgery is lifesaving. Believe it or not, there’s one procedure that’s been called out again and again for being done way more than it should. We’re talking about stent placement—also known as angioplasty—for people with stable heart disease. Here’s the kicker: lots of studies, including one huge trial called the COURAGE trial, have shown that putting a stent in someone with stable angina doesn’t actually lower the risk of a future heart attack compared to just taking medicines.
The problem is, stents sound like a quick fix. You go in, get your artery ‘opened up,’ and it feels like action is being taken. But if your symptoms aren’t severe or you’re not dealing with a heart attack, meds and lifestyle changes often work just as well—and sometimes even better. Thousands of people every year end up with stents or bypasses they probably didn’t truly need.

Surgery That Might Not Be Needed
When it comes to heart problems, a lot of folks think surgery is the only way out. But here’s the thing: most people with stable chest pain—what doctors call stable angina—don’t actually live longer or have fewer heart attacks after getting a stent or angioplasty. What works just as well? Good old medication and lifestyle tweaks.
The COURAGE trial and other big studies proved that for people who aren’t in immediate danger, surgery often doesn’t beat medicines like beta blockers, statins, and aspirin. For example, someone with clogged arteries might get told they need a stent right away, but if their symptoms are under control with meds, adding a stent usually doesn’t give them any extra protection. That’s a massive wake-up call for anyone being offered a heart surgery out of nowhere.
Here’s what usually makes people end up on the surgery list when they probably shouldn’t be:
- Mild or moderate symptoms that don’t mess with daily life
- No recent heart attack
- Test results that show stable heart disease and not anything dangerous
- No proof that medicine and lifestyle changes aren’t working
Unless you’re having a heart attack, surgery like a stent or bypass should never be the “default” answer. Always ask about meds and other options first.
Why Doctors Still Recommend Them
It sounds strange, but doctors often keep suggesting stents and other heart surgeries even when they might not help much. Part of it comes down to habit and comfort zone. Surgeons and cardiologists spend years learning how to do these procedures, so it's natural for them to lean towards what they know. Plus, patients expect action. If you walk into the office with chest pain, you want something fixed, not just another prescription.
There's also some serious pressure from the system. Hospitals and clinics make a lot more money from procedures than they do from follow-up visits or prescribing lifestyle changes. According to a 2023 study in JAMA, the average hospital charge for a single angioplasty in the U.S. was almost $30,000—compare that to a few hundred dollars for a few months of medicines and check-ups.
| Procedure | Average Hospital Charge (USD) |
|---|---|
| Angioplasty (Stent) | $29,700 |
| Bypass Surgery | $78,100 |
| Medication + Check-ups (6 months) | $500-$1,200 |
Another reason? Old guidelines die hard. It takes years for new research to show up in everyday practice. Some doctors worry about lawsuits if they don’t act aggressively. If something goes wrong, no one wants to be the person who ‘didn’t do enough.’
- Hospitals get paid much more for surgeries and procedures than for medical therapy.
- Many doctors genuinely believe stenting improves every patient’s life, because that’s what they’ve been taught.
- Insurance often covers the big-ticket heart surgery bills without question.
- Patients often ask for surgery, believing it’s the safest and fastest fix.
In short, old habits, money, and patient expectations all mix together. It’s not always easy to break the cycle, especially when the whole system gives a big thumbs-up to doing something, instead of waiting and watching.
Spotting the Red Flags
You don’t need a medical degree to question whether a heart surgery is truly necessary. Some warning signs should immediately push you to hit pause and ask more questions.
- Your doctor skips over or downplays medicine and lifestyle fixes and jumps straight to surgery.
- No one has explained if your symptoms are actually linked to blocked arteries that cause real trouble, or if your discomfort is mild and stable.
- You aren’t having major chest pains, breathlessness, or other clear signs of high-risk heart problems, but surgery still gets pushed as the only solution.
- Your test results are based on something vague—like a “borderline” finding on a scan, not a full-blown blockage or emergency.
- You didn’t get a second opinion, or you’re made to feel uncomfortable for wanting one.
If your doctor tells you there’s “no risk” with surgery or seems in a hurry to get you scheduled for the procedure, be careful. Modern data from the Cleveland Clinic shows that 30-50% of heart stent surgeries may be unnecessary, especially for stable patients.
| Red Flag | What It Means |
|---|---|
| No mention of medicine/lifestyle changes | Doctor rushing to operate without trying safer solutions first. |
| Symptoms not severe | You’re stable—surgery may add little or no benefit. |
| Poor explanation of test results | Unclear if there’s a real blockage or just a minor problem. |
| No time for second opinion | Pressure to agree quickly usually means the case isn’t urgent. |
When these red flags pop up, remember it’s okay to push for details and slow things down. A rushed or unclear recommendation usually benefits nobody except the hospital’s bottom line.
Real Risks of Unnecessary Heart Surgery
When it comes to heart surgery, going under the knife always comes with risks—even when the procedure isn’t actually needed. We’re not just talking about the bill (which can be massive), but some real dangers that can hit you hard and fast.
The top risks include:
- Major bleeding that sometimes requires another surgery
- Infections at the surgery site or inside your heart
- Stroke or mini-strokes caused by small blood clots
- Reactions to anesthesia or other medicines used during the procedure
- Kidney problems, sometimes permanent, if you already have kidney trouble
- Not feeling any better than before the surgery
The numbers back it up, too. A systematic review found that people getting elective stents for stable heart disease had a complication rate of about 5%—and that’s just the short-term stuff. Some of these problems can end up landing you back in the hospital, or worse.
| Type of Risk | Chance of Happening (Approx.) |
|---|---|
| Major Bleeding | 2-3% |
| Serious Infection | 1-2% |
| Death (during procedure) | 0.1-0.3% |
| Stroke | 0.4-0.6% |
Here’s something most folks don’t realize: going through unnecessary surgery can also make it harder for doctors to do any future procedures that you might actually need. Scar tissue builds up, arteries can get damaged, and recovery gets tougher each time.
“Every surgery has risk, and if it doesn’t clearly help the patient live longer or feel better, you should seriously question if it’s right for you.” — Dr. Rita Redberg, Professor of Cardiology, UCSF
Bottom line, if you’re told you need a heart procedure but you’re not in immediate danger, it’s absolutely okay to hit pause and double-check if it’s truly the best move for your health.
What to Do If You’re Told You Need Surgery
Getting told you need a heart procedure can be pretty scary. But take a breath—there are steps you can take to make sure you’re making the right move, especially when it comes to heart surgery like getting a stent or angioplasty.
The first thing you’ve got to know: ask questions. Don’t just accept the first recommendation, especially if your situation isn’t an emergency.
- Ask about your options. Will medication or lifestyle changes work just as well as surgery? Research shows for people with stable angina, medicines can control symptoms and protect against heart attacks about as well as surgery.
- Request clear numbers. How much does surgery lower your risk or help your symptoms, compared to doing something less invasive? Ask your doctor for facts and point them to big studies like the COURAGE trial, which found no difference in heart attack rates for stable patients who got stents versus those who just took meds.
- Get a second opinion. Seriously, this isn’t about hurt feelings—heart doctors expect it. Find a cardiologist at a different hospital or clinic, and get their take before making decisions. It’s your heart, and your choice.
- Check the procedure numbers. Some hospitals and doctors do lots more elective stent placements than others. It doesn’t always mean you’re getting better care—it might just mean they’re quicker to operate. Ask about it.
- Take your time (if it’s not an emergency). Unless you’re in the middle of a heart attack or have serious ongoing pain, most decisions can wait a day or even a week while you talk it over with your family or another doctor.
Here’s a quick look at how often stents are used for stable angina, and the percentage that experts say might not really be needed:
| Year | Total Stent Procedures* | Estimated Unnecessary (%) |
|---|---|---|
| 2020 | 500,000+ | 20-30% |
| 2022 | 520,000+ | 25-35% |

If you press your doctor for details and they can’t give clear answers, or get annoyed at your questions—it’s a red flag. Your health deserves open conversations and honest facts. And don’t forget, most insurers will pay for a second opinion; just call ahead and check. Take control and make the decision that fits your situation, not just what the hospital recommends out of habit.
Better Alternatives and Second Opinions
If your doctor says you need heart surgery, you don’t have to just go along with it, especially if we’re talking about stents for folks with stable heart disease. There are real alternatives, and getting another opinion can make a world of difference.
What should you consider first? Here’s a rundown of options that can actually work as well—or better—than going straight to surgery:
- Medications: For many stable heart problems, things like statins (for cholesterol), beta-blockers, aspirin, and meds to lower blood pressure do the heavy lifting. These drugs have been proven to cut heart attack and stroke risk for lots of patients without ever making a trip to the cath lab.
- Lifestyle Tweaks: We’re talking basics—quitting smoking, walking just 30 minutes a day, cutting back on junk food, and keeping an eye on weight and stress. The American Heart Association says these changes lower risk more than most people think.
- Cardiac Rehab: Not just for people after surgery—anyone with heart issues can benefit. Cardiac rehab teaches you what to eat, how to move, and how to keep your heart in the safe zone with real-life coaching.
Always consider seeing a different doctor before agreeing to surgery, especially if you’re not in an emergency. Studies have shown that when people get a second opinion on heart surgery, about 30% end up getting a totally different recommendation.
| Approach | Success Rate | Common Risks |
|---|---|---|
| Medication + Lifestyle | Up to 90% symptom control for stable angina | Side effects from meds, lifestyle changes can be tough |
| Stent Placement (for non-emergency) | No improved survival over meds for stable heart disease | Bleeding, blood clots, rare heart attack |
So, how do you actually go about getting that second opinion? Here’s how:
- Ask your current cardiologist for copies of your reports and test results.
- Find another specialist—preferably at a different hospital or practice.
- Bring all your info and ask, “Would you recommend a different approach based on my case?”
Don’t shy away from these questions. Most good doctors want you to get the best care, even if it means hearing another take. Your heart—and your future—deserve more than a one-size-fits-all fix.
