In this video, Dr. Lily Johnston addresses viewer questions about lipid panels, heart disease risk, and diagnostic testing. Key topics include:

Coronary Calcium Scans vs. CCTA/CIMT: Why calcium scores may not be sufficient for younger patients and the benefits of soft plaque detection.
Exercise and Lipids: Clarifying that while exercise is vital for longevity, its impact on LDL-C numbers is often minimal.
MRI vs. CT for Plaque: Why MRI is generally not the preferred tool for assessing arterial plaque buildup.
Inflammation and Cardiovascular Risk: A discussion on the "Zeus" trial and the ongoing relevance of inflammation in heart disease.
LDL-C to ApoB Ratios: Explaining discordance and why both particle count and cargo matter for risk assessment.
ApoB Particle Size: Debunking myths about "large fluffy" particles and emphasizing the importance of total particle burden.
N=1 Experiment: Dr. Lily reveals she will be testing both Dihydroberberine and Ezetimibe to observe their effects on her own lipid levels, starting with Dihydroberberine.
