My blood pressure normalization journey — July 2024

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

• NT-proBNP: 48 pg/mL (normal, cardiac function preserved)
• Lp(a): 28 nmol/L (genetic, unchanged — expected)
• ApoB: dropped from 148 to 88 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.

Mendelian randomization evidence supporting GLP-1 pathway modulation for cardiovascular risk: genetic variants in the GLP1R gene region associated with lower BMI also show associations with reduced cardiovascular risk, confirming a causal pathway[1].

This "natural experiment" (people born with genetically higher GLP-1 signaling being leaner and healthier) provides orthogonal evidence supporting the pharmacological approach. When genetic epidemiology, clinical trials, and mechanistic studies all converge, confidence in the therapeutic approach is high.

This matches mine closely enough to be worth saying so out loud. The detail I would add is minor and it is already implied above.

Adding the clinical framing, because it changes how the question reads.

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.
