For people with type 2 diabetes, lowering their blood pressure or bad cholesterol with GLP-1 drugs doesn't seem to make a noticeable difference in their risk of heart attack or stroke.
See the scientific wording
In patients with type 2 diabetes, reductions in systolic blood pressure and low-density lipoprotein cholesterol (LDL-C) achieved through GLP-1 receptor agonist therapy are not significantly associated with reductions in major adverse cardiovascular events (MACE).
Contradicted by evidence
One moderate-quality study contradicts this claim, though the evidence is not conclusive.

Systematic Review With Meta-AnalysisMeta-analysis2025
This study looked at whether lowering blood pressure and 'bad' cholesterol with GLP-1 drugs helps prevent heart attacks and strokes in diabetics — and found that those changes didn’t make a noticeable difference. So the claim is right.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether SBP and LDL-C changes consistently fail to mediate MACE reduction across GLP-1 RA trials.
A systematic review and meta-analysis of individual patient data from all GLP-1 RA CVOTs, testing SBP and LDL-C changes as mediators of MACE reduction using formal mediation analysis, adjusting for HbA1c and weight loss.
Whether adding intensive BP or LDL-C lowering to GLP-1 RA therapy provides additional MACE benefit beyond what is achieved by GLP-1 RAs alone.
A double-blind RCT of 4,000+ adults with type 2 diabetes and established CVD, randomized to GLP-1 RA + intensive BP/LDL-C lowering (target SBP <120, LDL-C <70) vs. GLP-1 RA + standard BP/LDL-C control, matched for HbA1c and weight change, with MACE as primary endpoint over 5 years.
Whether SBP and LDL-C changes predict MACE risk in type 2 diabetes patients on GLP-1 RAs in real-world settings.
A prospective cohort of 12,000+ adults with type 2 diabetes on GLP-1 RAs, tracking annual SBP and LDL-C changes over 6 years using electronic health records and linking to adjudicated MACE events, adjusting for HbA1c, weight loss, and medication adherence.
