Summary
Dr. Thomas Dayspring, a fellow of the National Lipid Association, delivers a deep dive into apolipoprotein B (ApoB) testing, target lab values for different risk profiles, and why standard cholesterol panels miss critical cardiovascular risk in women. He covers how estrogen loss during menopause raises ApoB and LDL, pregnancy complications as predictors of future heart disease, and the limitations of calcium scoring and CIMT for early detection.
Key Points
- ApoB is the single best blood marker for predicting cardiovascular risk because each atherogenic particle carries exactly one ApoB molecule.
- Target ApoB levels differ by risk profile: below 90 mg/dL for low risk, below 70 mg/dL for moderate risk, and below 50 mg/dL for high risk.
- Standard cholesterol panels can show "normal" LDL while masking high particle counts, particularly in insulin-resistant and post-menopausal women.
- Lp(a) should be tested at least once since it is genetically determined, not modifiable by diet or exercise, and dramatically increases cardiovascular risk when elevated.
- Menopause shifts lipid profiles unfavorably; women should get advanced lipid testing during perimenopause to establish a baseline before estrogen decline.
- Pregnancy complications (preeclampsia, gestational diabetes) signal future cardiovascular risk and should trigger earlier, more aggressive lipid monitoring.
Key Moments
ApoB targets depend on your baseline cardiovascular risk
Dr. Thomas Dayspring explains that optimal apoB levels depend on baseline risk, with aggressive targets around 30 for patients with known vascular disease and different goals for healthy women going through the menopausal transition.
"If you're a total nightmare, if you come walking in with a scar on your chest or you've had three st I'm going to want to turn you into an infant again with an apobia 30."
How estrogen loss in menopause raises LDL and cardiovascular risk
The episode explores how the loss of estrogen during menopause impairs the body's ability to clear LDL cholesterol, leading to higher apoB levels and increased cardiovascular risk that is specific to women's biology.

Pregnancy complications predict future heart disease risk in women
Dr. Dayspring identifies pregnancy-related clues that predict future cardiovascular risk for women, including gestational diabetes, preterm delivery, and early or late onset of menses as important signals that should be tracked.
