Tirzepatide cardiovascular safety — looking for input

Mendelian randomization evidence supporting GLP-1 pathway modulation for cardiovascular risk: genetic variants in the GLP1R gene region associated…

I'm 58 years old and want to share my perspective on cardiovascular risk as an older member of this community.

My doctor was initially hesitant because of my age, but the SELECT trial included patients up to 72 and showed consistent benefit across age groups. We started at the lowest dose with closer monitoring.

16 months later: down 63 lbs, off metoprolol, A1C from 8.6% to 5.4%. My cardiologist is thrilled. cardiovascular risk is absolutely relevant for older adults — don't let anyone tell you otherwise.

Genuinely useful, thank you. I had the facts and not the framework. Taking it to my next appointment.

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.

This is my experience too, for whatever a second data point is worth. Nothing to add that would improve it.

Positive "side effect" of cardiovascular risk: my blood pressure dropped so much that I'm now off amlodipine entirely! My cardiologist is thrilled.

If you're on BP meds and losing weight on a GLP-1, monitor your BP at home regularly. Hypotension symptoms (dizziness, lightheadedness when standing) mean your BP meds may need reduction. Don't wait for your next scheduled appointment — call your doctor.
