Collapse: Cardiovascular

Status: Reserved slug — full retrograde essay in development.

This is the first panel of the Terminal Event Diptych.

The Retrograde Chain

STEMI → Coronary plaque rupture → Endothelial dysfunction →
Chronic vascular inflammation → Circulating inflammatory mediators →
Bacterial extracellular vesicles (bEVs) → Periodontal pocket

Key Mechanisms (to be developed)

• Gingipain-mediated endothelial barrier disruption
• LPS-driven TLR4/NF-κB activation in vascular smooth muscle
• NLRP3 inflammasome assembly and IL-1β release
• bEV-mediated lipid deposition and plaque instability
• Biomineralization Hypothesis: vesicle-mediated

transition from soft plaque to calcified plaque

Pedagogical Method

Terminal Event Pedagogy — start with the MI,

work backward. The clinician already knows what a STEMI is. They don't need the

endpoint taught. They need the path from pocket to endpoint revealed.
