GLP-1 and atrial fibrillation risk — November 2025

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

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.

Metabolic syndrome resolution on cardiovascular risk: I went from meeting 5 of 5 diagnostic criteria to meeting ZERO after 13 months of treatment.

This is exactly what I could not find anywhere else. Adding it to my notes with a link back to this thread.

Vitamin deficiency cascade with cardiovascular risk: after 6+ months of reduced food intake, I developed a subtle but important pattern: low B12 → elevated homocysteine → increased cardiovascular risk marker.

The connection: B12 is a cofactor for homocysteine metabolism. Without adequate B12, homocysteine accumulates. This is ironic — taking a CV-protective medication while developing a CV risk factor from reduced nutrition.

Solution: comprehensive vitamin supplementation and regular lab monitoring. Don't let the medication's benefits be undermined by nutritional deficiencies.

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

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, -1.6 lbs/week average
Fasting glucose (finger stick): stable at 85 mg/dL
Blood pressure (home): 116/75 average
Resting heart rate: 65 bpm (down from 81)
Waist circumference: down 15 inches total

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