Recurrent Pericarditis as FMF Serositis Reaching the Heart

Put Stina’s heart story on one page and the pattern is unmistakable. This was not her first ‘chest thing’ — there had been earlier nights of sharp, breath-linked pain blamed on anxiety or reflux, never connected. Seen together, they are recurrent pericarditis: the same positional pain, the same rub, the same diffuse ECG, the same small effusion, returning again and again. No single episode looked like a systemic disease. The recurrence is the diagnosis.

Read against the rest of her chart, recurrent pericarditis is not a stand-alone heart condition — it is FMF serositis reaching the heart. The pericardium is a serous membrane, and in FMF the inflammasome drives IL-1β–mediated inflammation of exactly these linings, which is why the same patient gets peritonitis in the belly, pleuritis in the chest wall, and pericarditis around the heart. That is Chart Clue #15: Stina’s ‘heart attacks that weren’t’ are the serositis thread, already familiar from her abdomen and her lungs, surfacing at one more serous surface. The heart was never diseased on its own — its sac was simply the newest lining to catch the same fire.

The pericardium is a serous membrane, and the same IL-1β–driven inflammasome that produces peritonitis in her belly and pleuritis in her chest produces pericarditis around her heart. Positional pain, friction rub, diffuse ECG, small effusion, returning again and again — one disease, three linings, and a pump that was never diseased at all. The heart’s sac was simply the newest lining to catch the same fire.
