Echocardiographic changes on GLP-1 — my results so far

Dr.SportsMedIN said:

SUSTAIN-6 was the first CVOT to show cardiovascular benefit with semaglutide, relevant to cardiovascular risk.

I read this differently from Dr.SportsMedIN, on substance rather than tone. The "earlier than weight loss explains" argument is weaker than this thread makes it sound. Blood pressure and inflammatory markers move fast and are downstream of early weight loss, so the mechanism is not as cleanly separable as the summaries imply.

Prescribed on cardiovascular grounds rather than for weight, and almost everything written for patients assumes the opposite.

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

• NT-proBNP: 67 pg/mL (normal, cardiac function preserved)
• Lp(a): 27 nmol/L (genetic, unchanged — expected)
• ApoB: dropped from 147 to 92 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.

I want to bring up the cardiovascular angle on cardiovascular risk.

The SELECT trial demonstrated a 20% reduction in MACE with semaglutide 2.4mg[1]. This is practice-changing because the CV benefit appears to be independent of the degree of weight loss — suggesting direct vascular and anti-inflammatory mechanisms.

For cardiovascular risk, this means we need to think beyond the primary outcome and consider the cardiovascular implications. The all-cause mortality reduction (HR 0.81) is the most clinically meaningful signal.

Following on from josh_phd_bmore — and this may be the naive question:

How long did you give it before you decided it was working?

Positive "side effect" of cardiovascular risk: my blood pressure dropped so much that I'm now off lisinopril 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.
