Frame
Dressler syndrome / PCIS — autoimmune pericarditis 2-12 wk post-cardiac-injury; high-dose ASA + colchicine first-line (preferred post-MI); NSAIDs + colchicine alternative (post-surgery); corticosteroids reserved for refractory; pericardiocentesis only if tamponade (~10-20% of cases) (ESC 2015 §Post-Cardiac Injury Syndrome; Imazio CIRCS NEJM 2015 PMID 26315582)
PCIS context with appropriate timing post-injury suspected
Patient inputs (11)
Older patients have higher post-MI Dressler risk + worse drug tolerance (Adler 2015 BMJ)
Compensatory tachycardia in tamponade physiology + low-grade tachycardia from inflammation (Imazio ICAP PMID 23992557)
MI vs CABG vs valve surgery vs lead implant vs ablation vs trauma; days-weeks elapsed since injury — drives diagnosis confidence + therapy selection (ASA preferred post-MI vs NSAID acceptable post-surgery) (ESC 2015; Imazio CIRCS PMID 26315582)
DAPT / DOAC / warfarin status drives hemorrhagic component risk + NSAID safety + pericardiocentesis bleeding risk (ESC 2015)
Low-grade fever (typically 37.5-38.5°C) is a hallmark — present in ~70-80% of cases (Adler 2015 BMJ)
Definitive bedside dx — chamber collapse, IVC, swinging heart if tamponade; effusion size + character drives drainage decision (ESC 2015 Class I)
CRP elevation is a key diagnostic criterion + treatment response marker; trend to <1 mg/dL guides therapy de-escalation (Imazio ICAP PMID 23992557)
Leukocytosis present in ~60-70% of cases; supports diagnosis when other criteria present (Adler 2015 BMJ)
Baseline for NSAID + colchicine renal dose adjustment (CrCl <30 → avoid colchicine) + ASA renal safety (ESC 2015)
Often mildly elevated from associated myopericarditis component; helps differentiate from re-infarction (Adler 2015 BMJ)
Hypotension is part of Beck triad if tamponade physiology develops (~10-20% of cases) (ESC 2015)

Assessment
**Cardiac tamponade — Dressler syndrome (post-cardiac-injury syndrome)** (cardio.cardiac-tamponade.dressler-syndrome.v1). Phenotype framing: Differentiate PCIS from: (1) re-infarction (serial troponin trend + cath if rising); (2) infectious pericarditis (no fever pattern + elevated procalcitonin + positive cultures); (3) malignant effusion (cancer history + cytology); (4) uremic pericarditis (CKD context + BUN >100); (5) post-procedural bleeding (no inflammatory markers, anticoagulation context). Pericardial fluid analysis ONLY if tamponade requiring drainage (ESC 2015; Adler 2015 BMJ) Scope: Dressler syndrome / PCIS — autoimmune pericarditis 2-12 wk post-cardiac-injury; high-dose ASA + colchicine first-line (preferred post-MI); NSAIDs + colchicine alternative (post-surgery); corticosteroids reserved for refractory; pericardiocentesis only if tamponade (~10-20% of cases) (ESC 2015 §Post-Cardiac Injury Syndrome; Imazio CIRCS NEJM 2015 PMID 26315582) No severity triggers fired against current inputs.

Disposition
Current setting: outpatient — CRP-guided anti-inflammatory taper completion at 6-8 wk; colchicine 3-mo completion; recurrence surveillance (~30% risk); pericardiectomy reserved for rare constrictive sequelae (ESC 2015; Imazio ICAP PMID 23992557) Disposition criteria: - Long-term continuation under cardiology + PCP; biologics if refractory recurrent; pericardiectomy if constriction develops; cross-link to cardio.cardiac-tamponade.core.v1 for acute recurrence pathway Escalation triggers (move to higher acuity): - Recurrent pericarditis (≥1 episode after symptom-free interval) → extend colchicine to 6 mo per CORP + restart anti-inflammatory - Multiple recurrences (≥2 episodes) → CORP-2 protocol + consider rheumatology consult - Refractory recurrent pericarditis with steroid dependence → azathioprine or anakinra per ESC 2015 + AIRTRIP - Constrictive pericarditis (rare in PCIS but possible) → CMR + RH cath + cardiothoracic for pericardiectomy - Tamponade recurrence → ED for echo + drainage
