STEP-HFpEF: semaglutide in heart failure with preserved EF — March 2026

Clinical perspective, offered as context rather than as advice.

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.

Lp(a) and cardiovascular risk: a nuance that matters.

Saving this. It is the first explanation that did not require me to already understand it.

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

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, -2.2 lbs/week average
Fasting glucose (finger stick): stable at 85 mg/dL
Blood pressure (home): 117/75 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.

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