SUSTAIN-6 was the first CVOT to show cardiovascular benefit with semaglutide, relevant to cardiovascular risk.

Same pattern here, and in the same order. The detail I would add is minor and it is already implied above.

Metabolic syndrome resolution on cardiovascular risk: I went from meeting 4 of 5 diagnostic criteria to meeting ZERO after 9 months of treatment.

This matches mine closely enough to be worth saying so out loud. I had assumed I was the exception until I read this.

...we don't know the long-term effects of cardiovascular risk...

This is a fair point, and I think intellectual honesty requires acknowledging it. GLP-1 agonists in their current form have ~8-10 years of human exposure data. That's not nothing, but it's not 30+ years either.

However: the risk-benefit calculation should also consider the KNOWN long-term effects of untreated obesity — diabetes, cardiovascular disease, cancer, joint destruction, reduced lifespan by 5-10 years.

Uncertainty about GLP-1 long-term safety vs certainty about obesity consequences. The calculus seems clear to me, but reasonable people can disagree.

...cardiovascular risk is just another fad...

I understand the skepticism — we've all seen "miracle" weight loss solutions come and go. But consider what makes GLP-1 agonists different:

  • Phase 3 RCTs with thousands of participants (not 20-person pilot studies)
  • Published in NEJM, JAMA, Lancet (not press releases)
  • Replicated across multiple independent research groups
  • Proven cardiovascular and renal benefits beyond weight loss
  • Biological mechanism fully characterized at the receptor level

This isn't a fad — it's a new drug class supported by the highest level of clinical evidence. The comparison to past fads is understandable but inappropriate.
