Dizziness and cardiovascular risk: I was lightheaded for the first 3 weeks.

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

• NT-proBNP: 53 pg/mL (normal, cardiac function preserved)
• Lp(a): 43 nmol/L (genetic, unchanged — expected)
• ApoB: dropped from 153 to 93 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 Dr.ObesityLA’s answer:

Was that from a primary source or from a summary of one?

Metabolic syndrome resolution on cardiovascular risk: I went from meeting 3 of 5 diagnostic criteria to meeting ZERO after 14 months of treatment.

The 5 criteria (and my journey):

1. Waist circumference: 53" → 37" ✅ Resolved
2. Triglycerides: 267 → 117 ✅ Resolved
3. HDL: 37 → 59 ✅ Resolved
4. Blood pressure: 147/93 → 120/74 ✅ Resolved
5. Fasting glucose: 117 → 89 ✅ Resolved

Metabolic syndrome reversal is, in my view, the most medically significant outcome of GLP-1 therapy.

Lp(a) and cardiovascular risk: a nuance that matters. Unlike most lipid markers, Lp(a) is 90%+ genetically determined and doesn't really change with weight loss or GLP-1 therapy.

My Lp(a) has remained at 47 nmol/L across all time points. If yours is elevated (>50 nmol/L), you need additional risk mitigation strategies regardless of your GLP-1 response. Don't assume your medication is covering all cardiovascular risk factors.

Genuinely useful, thank you. I had the facts and not the framework. Printing the relevant bit and taking it with me.
