From the other side of the consultation, briefly.

Anti-inflammatory mechanisms of GLP-1 agonists and cardiovascular risk: beyond weight loss, GLP-1R activation directly suppresses NF-κB signaling, reduces NLRP3 inflammasome activation, and decreases monocyte/macrophage adhesion to endothelium[1].

Clinical correlates: hsCRP reduction of 30-60% (consistently seen across trials), reduced carotid intima-media thickness, and decreased coronary plaque inflammation on PET imaging.

These anti-inflammatory effects likely contribute to the cardiovascular benefit seen in SELECT — and may explain benefits beyond what weight loss alone would predict.

This matches mine closely enough to be worth saying so out loud.

Continuous metabolic monitoring dashboard for cardiovascular risk — I track everything in a spreadsheet and here's the month-over-month trend for my key markers:

Weight: consistent downtrend, -2.4 lbs/week average
Fasting glucose (finger stick): stable at 87 mg/dL
Blood pressure (home): 119/73 average
Resting heart rate: 67 bpm (down from 83)
Waist circumference: down 17 inches total

The resting heart rate improvement correlates with cardiovascular fitness gains. Everything is moving in the right direction.

Cardiac biomarkers and cardiovascular risk: my cardiologist ordered advanced cardiac labs given my family history. Results were encouraging:

  • NT-proBNP: 58 pg/mL (normal, cardiac function preserved)
  • Lp(a): 58 nmol/L (genetic, unchanged — expected)
  • ApoB: dropped from 143 to 98 mg/dL (excellent response)
  • Coronary calcium score: 0 (unchanged from baseline — reassuring)

The ApoB reduction is particularly meaningful — it's considered the best single predictor of cardiovascular risk. GLP-1 therapy seems to improve this consistently.

One thing that is still open after NurseKim_ATL’s answer:

How long did you give it before you decided it was working?
