Heart rate increase on GLP-1 — need advice

SELECT is the trial that changed the framing of this class, because it was an outcome trial rather than a weight trial: about a 20% relative reduction…

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.

Following on from Dr.LipidDallas — and this may be the naive question:

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

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.

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, -1.5 lbs/week average
Fasting glucose (finger stick): stable at 88 mg/dL
Blood pressure (home): 115/74 average
Resting heart rate: 68 bpm (down from 84)
Waist circumference: down 18 inches total

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

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

Baseline hsCRP: 9.0 mg/L (high cardiovascular risk)
Month 6 hsCRP: 2.5 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 16% to 5%. My cardiologist is genuinely impressed.
