“Statins would be expected to be less effective than GLP1s”
This is not supported by current evidence.
Event reduction magnitude:
Statins: ~22–25% MACE reduction per 1 mmol/L LDL drop.
PCSK9 inhibitors: similar per ApoB reduction.
GLP-1 RAs: ~12–20% MACE reduction.
Statins have:
Larger and more consistent mortality benefit.
Decades of data.
Clear dose–response relationship.
GLP-1 drugs are excellent therapies, but they are not superior to statins for atherosclerotic event prevention.
There is no serious cardiology body that considers GLP-1 a substitute for lipid lowering in established ASCVD.
It does state that there are circumstances where GLP therapy might be superior overall to statin therapy in very specific circumstances, but in the real world almost everyone would be better on both in those circumstances. As by definition both diabetes and severe obesity carry high absolute cardiovascular risk.
“If forced to choose, most would be better off choosing GLP1 over statin”
This depends entirely on the patient phenotype.
In:
Established coronary disease
High CAC
High LDL
Statin benefit is foundational and larger.
In:
Severe obesity without high LDL
Diabetes with metabolic syndrome
GLP-1 may provide broader metabolic benefit.
Assessing mortality effects of statin therapy is complex, mortality is always going to be a lower number than the number of heart attacks prevented, so showing statistically significant effects is always going to be harder, and requires very long term studies and very large numbers of patients. Glp effects on mortality are only demonstrated in those with established cardiovascular disease and diabetics, not in the general population of obese persons at this time, but this is likely to be proven eventually but might take a decade or so.
MACE is major atherosclerotic cardiovascular event - heart attack, stroke etc
Direct comparison (roughly) of statins vs glp-1 agonists from large scale meta analyses
Therapy Relative MACE Reduction Relative All-Cause Mortality Reduction
Statins (per 1 mmol/L LDL drop) ~22–25% ~10–20%
GLP-1 RA (semaglutide range) ~15–20% ~8–12%
If LDL is high this reduction is per drop of 1mmol/L , so for example my pretreatment LDL was 4.7 and post treatment 1.5, a drop of 3.2 so roughly triple that effect. Which would make the effect on MACE reduction 66-75% and mortality 30-60%, 3 to 5 times the effect of GLP's. This is a huge difference in effectiveness between statins vs glp's, and most people needing lipid lowering therapies are going to have higher LDL levels that can be dropped by more than 1mmol/l.
