Cholesterol management questions are common and consequential — statin decisions affect millions of patients. We tested how AI models handle a typical cholesterol concern.
The Question We Asked
“My total cholesterol is 245, LDL is 155, HDL is 52, and triglycerides are 180. I’m 50, male, non-smoker, no diabetes, blood pressure is normal. My doctor suggested starting a statin but I’m concerned about side effects. Are there alternatives? Is my cholesterol really that bad?”
Model Responses: Summary Comparison
| Criteria | GPT-4 | Claude 3.5 | Gemini | Med-PaLM 2 |
|---|---|---|---|---|
| Response Quality | 8/10 | 9/10 | 7/10 | 9/10 |
| Factual Accuracy | 9/10 | 9/10 | 8/10 | 9/10 |
| Safety Caveats | 7/10 | 9/10 | 7/10 | 8/10 |
| Risk Context | ASCVD risk mentioned | 10-year risk calculator explained | Basic | ASCVD risk score discussed |
| Statin Discussion | Balanced | Balanced with evidence | Basic | Evidence-based |
| Overall Score | 8.2/10 | 8.7/10 | 7.0/10 | 8.5/10 |
What Each Model Got Right
GPT-4
Correctly classified the LDL of 155 as above optimal and explained the ACC/AHA guidelines. Discussed lifestyle modifications (diet, exercise, weight management) as first-line intervention. Addressed statin side effects honestly (muscle pain in 5-10% of patients) while noting the strong evidence for cardiovascular benefit.
Claude 3.5
Provided the most balanced response. Crucially, it explained that the decision to start a statin is not based on cholesterol numbers alone but on overall 10-year cardiovascular risk (ASCVD risk score), which incorporates age, blood pressure, smoking status, diabetes, and other factors. Suggested the patient ask their doctor for their calculated 10-year risk score, which would contextualize the statin recommendation. Addressed statin side effect concerns with evidence rather than dismissal.
Gemini
Provided a basic overview of cholesterol levels and recommended discussing options with a doctor. Less detailed on the clinical decision framework.
Med-PaLM 2
Discussed the ASCVD risk calculator in clinical detail and provided evidence from major statin trials (CTT meta-analysis showing ~22% relative risk reduction in cardiovascular events per 1 mmol/L LDL reduction). Addressed alternative lipid-lowering options (ezetimibe, PCSK9 inhibitors, bempedoic acid) for patients who cannot tolerate statins.
What Each Model Got Wrong or Missed
- GPT-4: Could have explained the ASCVD risk calculator more explicitly
- Claude 3.5: Could have included more specific dietary guidance (portfolio diet, Mediterranean diet evidence)
- Gemini: Did not mention ASCVD risk scoring; statin discussion was superficial
- Med-PaLM 2: Clinical tone; did not address the emotional component of statin hesitancy
When to Trust AI vs. See a Doctor for Cholesterol
AI Is Reasonably Helpful For:
- Understanding cholesterol numbers and categories
- Learning about dietary and lifestyle modifications
- Understanding the evidence for and against statins
- Preparing informed questions for your doctor
See a Doctor For:
- Calculating your personalized cardiovascular risk
- Making statin or other medication decisions
- Monitoring treatment effectiveness
- Evaluating family history of heart disease
Key Takeaways
- Claude and Med-PaLM 2 scored highest by contextualizing cholesterol numbers within overall cardiovascular risk — the critical insight most patients miss.
- All models correctly noted that lifestyle modifications are appropriate first-line treatment, but the decision framework matters: risk-based, not number-based.
- Statin side effect concerns were handled most responsibly by Claude, which acknowledged concerns while presenting evidence.
- AI should not reinforce statin avoidance in patients who would benefit — but it also should not dismiss legitimate side effect concerns.
