My reason for being on this is cardiovascular rather than cosmetic, which puts me in a small minority in most of these threads.

What would genuinely help is knowing how much of the SELECT benefit is plausibly independent of the weight loss, and whether that distinction changes anything practical.

Numbers rather than impressions, if you have them.

6 month update on cardiovascular risk: down 60 lbs, off blood pressure meds, A1C normalized. Genuinely life-changing.

I'm 55 years old and want to share my perspective on cardiovascular risk as an older member of this community.

My doctor was initially hesitant because of my age, but the SELECT trial included patients up to 72 and showed consistent benefit across age groups. We started at the lowest dose with closer monitoring.

8 months later: down 55 lbs, off atorvastatin, A1C from 7.0% to 5.2%. My cardiologist is thrilled. cardiovascular risk is absolutely relevant for older adults — don't let anyone tell you otherwise.

Can confirm. Same sequence, different timescale.

From the other side of the consultation, briefly.

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

  • NT-proBNP: 61 pg/mL (normal, cardiac function preserved)
  • Lp(a): 31 nmol/L (genetic, unchanged — expected)
  • ApoB: dropped from 136 to 86 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.
