CAC 525 stenosis at 35yo with Kawasaki disease: what to do?

35yo caucasian male, amateur endurance runner (15h/w), RHR 45bpm, lean 80kg/183cm, healthy diet, never smoked, non-drinker.
Childhood (5yo) Kawasaki disease coronary aneurysms: fusiform dilation of proximal LAD and 7-8mm spherical aneurysm on RCA.
By age 19, coronary aneurysms had fully regressed to normal luminal diameter, zero stenosis, and strictly extra-luminal calcification.

Recently experienced an altitude-triggered hypertensive crisis (170 BP) → investigated with cardio:

  • CAC 525
  • CCTA: mild (25–49%) stenosis in the proximal LAD (eccentric mixed plaque) and in the mid RCA (arc-like calcification); zero aneurysms remaining
  • 48h Holter: non-remarkable
  • 24h ABPM: non-dipping pattern (systolic only -2% at night)

… DESPITE (UNMEDICATED):

  • ApoB 73 mg/dL
  • LDL 3.00 mmol/L (1.87 mmol/L 2 years before hypertensive crisis)
  • hs-CRP 1.33 mg/L (<0.34 mg/L 2 years before hypertensive crisis)
  • Lp(a) <10 mg/dL
  • Fasting glucose 4.5 mmol/L

Cardio put me on:

  • Rosuvastatin 10mg + Ezetimibe 10mg
  • Telmisartan 80mg + Amlodipine 5mg
  • Aspirin 100mg

Medicated outcome:

  • ApoB 51 mg/dL
  • LDL 1.41 mmol/L
  • hs-CRP 0.98 mg/L
  • BP 110/65

Kawasaki is a rare condition so it is hard to find answers on targets to stabilise/regress plaque. I wonder:

  1. ApoB: Target even lower? Add a PCSK9i and/or Bempedoic Acid? (wary of BA due to the tendon rupture risk with high running volume)

  2. Aspirin: Aneurysms fully regressed + recent low altitude epistaxis while medicated: does the haemorrhagic risk outweigh the prophylactic protection against cap rupture at 25–49% mixed stenosis? - Family history: one grandparent died of aortic dissection, another of haemorrhagic stroke, and my mother had two thrombotic strokes in her 40s linked to ultra-high BP (230 unmedicated and 150-160 medicated).

  3. CRP: Target even lower? Low-dose colchicine?
