Names & Terms You Will Hear
Plain-language meanings for the terms your care team may use.
| Term | Meaning |
|---|---|
| Pericarditis | Inflammation of the pericardium — the two-layer sac around your heart. |
| Acute pericarditis | New episode lasting less than 4-6 weeks. |
| Recurrent pericarditis | Another flare after a symptom-free interval of 4-6 weeks or more. |
| Incessant pericarditis | Symptoms persist beyond 4-6 weeks without remission. |
| Constrictive pericarditis | Scarred, stiff sac that squeezes the heart — a long-term complication. |
| Myopericarditis | Pericarditis with mild heart-muscle inflammation (small troponin bump). Usually still benign. |
| Dressler's syndrome | Pericarditis 2-8 weeks after a heart attack or heart surgery — immune-mediated. |
| Idiopathic pericarditis | No cause found; in developed countries this is most cases — usually a recent viral infection. |
What Is Pericarditis?
- Your heart sits inside a two-layer sac called the pericardium. A normal sac holds 15-50 mL of slippery fluid that lets the heart glide.
- When the sac gets inflamed, the layers rub. That rubbing causes a sharp, stabbing chest pain that is usually worse when you lie down and better when you lean forward.
- Doctors diagnose pericarditis when at least 2 of these are present: typical chest pain, a friction rub on the stethoscope, diffuse ST-elevation or PR-depression on EKG, or a new pericardial effusion on echo.
- Most acute pericarditis in the US is idiopathic (no cause found) or follows a viral illness (Coxsackie, echovirus, COVID-19). Worldwide, tuberculosis is still common.
- Pericarditis can come with extra fluid in the sac (effusion). A small effusion is usually safe; a large one can compress the heart (tamponade) and is an emergency.
- About 30% of patients have a recurrence without colchicine. Colchicine cuts recurrence in half (ICAP, COPE, CORP-2 trials).
Why It Matters
- Acute pericarditis pain mimics a heart attack, sends patients to the ED, and is often misdiagnosed in both directions.
- Getting the diagnosis right matters because treatment is very different from a heart attack — and so is the prognosis (usually excellent).
- Without colchicine, recurrence is common. Each recurrence raises the risk of further recurrences. Early, full-dose colchicine breaks that cycle.
- Steroids early on (without a clear immune indication) increase recurrence and are reserved for true NSAID/colchicine failures.
- Rarely, untreated or scarring pericarditis becomes constrictive — a stiff sac squeezing the heart, with symptoms of right-sided heart failure. This requires pericardiectomy.
Risk Factors
Knowing your personal risks helps your care team take extra precautions.
| Risk Factor | Why It Increases Risk |
|---|---|
| Recent viral infection | Coxsackie, echovirus, influenza, and now COVID-19 are common triggers. Often the trigger is never identified. |
| Recent heart attack or heart surgery | Pericardial inflammation 2-8 weeks later (Dressler's syndrome) is immune-mediated. |
| Autoimmune disease | Lupus, rheumatoid arthritis, scleroderma, vasculitis, and familial Mediterranean fever can all cause pericarditis. |
| Kidney failure (uremic pericarditis) | Toxins built up in advanced kidney disease can inflame the sac. Improves with dialysis. |
| Cancer (lung, breast, lymphoma) | Tumor seeding of the pericardium or radiation effects. Often presents as a large effusion. |
| Tuberculosis | Major worldwide cause; rare in the US except in immigrants and immunocompromised hosts. |
| Recent cardiac procedure (catheter ablation, pacemaker) | Up to 1-2% of ablations have post-procedure pericarditis. |
| Radiation to the chest | Can scar the pericardium over years; raises constrictive-pericarditis risk. |
Treatment Options
Shown in English for your safety — this section is not automatically translated. Confirm with your doctor or call the office.
- First-line: NSAIDs + colchicine. The standard combo per ICAP/COPE trials. Either ibuprofen 600 mg three times a day or aspirin 750-1000 mg three times a day, tapered over 2-4 weeks.
- Colchicine 0.5 mg twice a day (or once a day if under 70 kg or kidney issues) for 3 full months on a first episode. Cuts recurrence by ~50%.
- Recurrent episode. Repeat NSAID course, plus colchicine for 6+ months (CORP-2 dosing). The longer course matters.
- Steroids are NOT first-line. They actually increase recurrence in viral/idiopathic disease. Reserved for autoimmune cases, NSAID failure, or when NSAIDs are contraindicated (pregnancy, severe kidney disease).
- IL-1 blockers (anakinra, rilonacept) for steroid-dependent or multi-recurrence patients. RHAPSODY (2021) showed rilonacept dramatically cuts recurrence.
- Acetaminophen + opioids are NOT enough — they relieve pain but do not treat inflammation. NSAIDs are doing the actual work.
- Restrict strenuous exercise until symptoms resolve, EKG changes settle, and inflammation markers (CRP) normalize — typically 3 months for athletes, less for non-athletes.
- Constrictive pericarditis -> pericardiectomy at an experienced center if symptomatic and refractory.
- Cardiac tamponade (large effusion compressing the heart) -> emergency drainage (pericardiocentesis).
Risks, Benefits, and Alternatives
Shown in English for your safety — this section is not automatically translated. Confirm with your doctor or call the office.
Every choice has trade-offs. Use this table to start the shared decision conversation with your care team.
| Option | Risks | Benefits | Alternatives |
|---|---|---|---|
| NSAID + colchicine (3 months) | GI upset, ulcers (NSAID); diarrhea (colchicine, dose-dependent); rare kidney effects; drug interactions with statins. | Standard of care. ~50% reduction in recurrence. Most patients fully recover. | NSAID alone (higher recurrence); steroid (higher recurrence). |
| Repeat NSAID + extended colchicine (6+ months) for recurrence | Same side effects; longer exposure. | Breaks the recurrence cycle. CORP-2 evidence base. | Add low-dose steroid; IL-1 blocker. |
| Low-dose prednisone (last-resort or autoimmune cases) | Weight gain, bone loss, glucose elevation, mood changes; higher recurrence rate. | Works fast for pain. Useful when NSAIDs are not safe. | Stick with NSAID/colchicine; add IL-1 blocker. |
| IL-1 blocker (rilonacept or anakinra) | Injection-site reactions, infection risk; cost. | Steroid-sparing for multi-recurrent disease. RHAPSODY showed dramatic recurrence reduction. | Long-term colchicine + low-dose steroid; pericardiectomy in extreme cases. |
| Pericardiectomy (surgical removal of the sac) | Open-heart surgery: mortality 5-10% in best centers; long recovery. | Curative for chronic constrictive pericarditis. The only definitive option once scarring is fixed. | Continued medical therapy; symptomatic management. |
| No treatment (NSAIDs only without colchicine) | 30% or higher recurrence rate. More ED visits. | Avoids colchicine GI effects. | Add colchicine. |
Common Misconceptions
| Myth | Reality |
|---|---|
| "My chest pain has to be a heart attack." | Pericarditis pain is sharp, pleuritic (worse with deep breath), worse lying down, and better leaning forward. Heart-attack pain is usually heavy pressure, not pleuritic, and not positional. The EKG patterns also differ — diffuse ST elevation with PR depression is pericarditis, not a heart attack. |
| "Just put me on steroids — they work the fastest." | Steroids feel good in week one and cause trouble for months. Multiple studies show early steroids increase recurrence in viral/idiopathic pericarditis. NSAIDs + colchicine is slower to relieve pain but produces fewer recurrences. |
| "I should stay in bed for weeks." | Mild activity is fine and probably helpful. Only strenuous exercise and competitive sports need to wait until inflammation markers (CRP) normalize. |
| "Once it is gone, it can't come back." | About 30% of untreated patients recur. Even with treatment, 15-20% have a recurrence. That is why colchicine is given for a full 3-6 months, not just until pain resolves. |
| "Colchicine is just for gout." | Colchicine is one of the most important medications in modern pericarditis care. The ICAP, COPE, and CORP-2 trials all showed it cuts recurrence by about half. We dose it 0.5 mg once or twice daily for 3-6 months. |
| "Pericarditis means I will get heart failure." | Constrictive pericarditis is uncommon (less than 1% of acute viral cases). Most patients recover fully with no long-term cardiac problems. |
Possible Complications
Knowing what can go wrong helps you spot problems early. Most complications are uncommon, especially with treatment.
| Where / What | What Can Happen |
|---|---|
| Pericardial effusion | Extra fluid in the sac. Small effusions are common and usually safe. Large effusions can compress the heart. |
| Cardiac tamponade | An emergency — fluid compresses the heart, dropping blood pressure. Needs immediate drainage (pericardiocentesis). |
| Recurrent pericarditis | 30% rate without colchicine; ~15% with. Most respond to repeating the NSAID/colchicine course. |
| Constrictive pericarditis | Scarred, stiff sac. Causes leg swelling, fatigue, ascites — looks like right-sided heart failure. May need pericardiectomy. |
| Myopericarditis | Mild heart-muscle involvement (small troponin bump). Usually still benign but requires more exercise restriction. |
| Atrial fibrillation | Sometimes triggered during the acute inflammatory phase. Often resolves once inflammation settles. |
Points to Know
Shown in English for your safety — this section is not automatically translated. Confirm with your doctor or call the office.
If you remember nothing else, remember these key points.
- The classic clue: sharp chest pain that is worse lying flat and better leaning forward.
- First-line treatment is NSAID + colchicine for 3 months. Not steroids.
- About 30% recur without colchicine; closer to 15% with. Finish the full colchicine course even if you feel better.
- Strenuous exercise and competitive sports wait until your CRP normalizes (often 3 months in athletes).
- Watch for shortness of breath, fast heartbeat, or low BP — these can mean tamponade and need immediate care.
- If you have a second episode, a third, or are dependent on steroids, ask about IL-1 blockers (rilonacept / anakinra).
