GLP-1 and atrial fibrillation risk — November 2025

CRP reduction on cardiovascular risk — this is the lab result that excites me most:

Baseline hsCRP: 11.0 mg/L (high cardiovascular risk)
Month 6 hsCRP: 3.5 mg/L (moderate risk)
Month 12 hsCRP: 0.7 mg/L (low risk)

This level of inflammatory marker reduction is comparable to what you'd see with statin therapy. Combined with the weight loss, my 10-year ASCVD risk score dropped from 18% to 6%. My cardiologist is genuinely impressed.

Positive "side effect" of cardiovascular risk: my blood pressure dropped so much that I'm now off metoprolol entirely! My cardiologist is thrilled.

If you're on BP meds and losing weight on a GLP-1, monitor your BP at home regularly. Hypotension symptoms (dizziness, lightheadedness when standing) mean your BP meds may need reduction. Don't wait for your next scheduled appointment — call your doctor.

This answered a question I did not know how to ask. Taking it to my next appointment.

Clinical perspective, offered as context rather than as advice.

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.

Same pattern here, and in the same order. Posting only so the count is not one.
