Here's the HR data across the major GLP-1 RA trials for reference:
| Trial | Drug / Dose | Mean HR Increase vs. Placebo (bpm) |
|---|---|---|
| SUSTAIN-6 | Sema 0.5/1.0 mg | +2.5 |
| SELECT | Sema 2.4 mg | +3.4 |
| STEP 1 | Sema 2.4 mg | +2.3 |
| SURPASS-2 | Tirz 5/10/15 mg | +2.0 to +3.6 |
| LEADER | Liraglutide 1.8 mg | +3.0 |
These are means, and individual variation is substantial (standard deviations of ~5-8 bpm). The OP's 14 bpm increase is approximately 1.5-2 standard deviations above the mean, so it's an above-average response but within the observed distribution.
Notably, in none of these trials did the HR increase translate into excess cardiovascular events. The HR increase appears to be a pharmacological effect without adverse clinical consequences in the studied populations.
