Episode Summary
Dr. Lucy McBride sits down with Dr. Greg Katz, cardiologist and educator at NYU, to make sense of the new 2026 cholesterol guidelines — and what they actually mean for real patients. Together, they cut through the noise on coronary artery calcium scores, Lp(a), statins, GLP-1s, and the lifestyle factors that matter most for heart health. The upshot: we treat people, not numbers.
The New Cholesterol Guidelines — Goals and Limits
The 2026 guidelines were released in March, endorsed by eleven groups of medical experts, and they reflect a synthesis of existing cardiovascular evidence, not new data.
The goal of updated guidelines isn’t for doctors (or patients) to treat them as the Bible, but rather to help assess cardiovascular risk, estimate the benefit of various interventions, and help patients understand how medical evidence applies to them.
Guidelines are built on large populations; they can’t account for the individual patient sitting in front of you. For example, two people with identical LDL levels can have entirely different risk profiles, family histories, reasons their cholesterol is elevated, and therefore completely different treatment pathways.

Coronary Artery Calcium Scores — What They Can and Can’t Tell You
A calcium score looks for calcified, hardened plaque in the coronary arteries — it tells you about the “plumbing,” not the whole story of a patient’s heart health.
A score of zero doesn’t mean you have no plaque; soft plaque is invisible on this test and can still cause blockages.
A non-zero score doesn’t mean a heart attack is imminent — age, sex, and the rest of your risk profile matter enormously.
When doctors overreact to elevated scores, it can set off a cascade of unnecessary tests and procedures and lead to patient anxiety. As always, context and appropriate communication matter when transmitting information to patients.
Blood Pressure: The Underappreciated Risk Factor
Blood pressure is probably the most underappreciated driver of cardiovascular risk — contributing to heart disease, heart failure, kidney failure, and dementia.
If someone has an elevated calcium score and imperfect blood pressure, controlling the blood pressure often matters more than starting a statin.
Most heart disease prevention comes down to three things: blood pressure, cholesterol, and metabolic health (Read more on what your blood pressure is telling you here).
Statins — Who Needs Them, and What the Side Effects Actually Mean
Statins reduce cardiovascular risk by about 20-25% on average — but if your baseline risk is very low, 20% of near-zero is still near-zero!
Side effects are real but manageable: about 8-10% of people get muscle aches that are predictable and reversible when the medication is stopped.
Claims that statins cause diabetes are overblown — the blood sugar rise is not inevitable and often is small and predictable.
Non-statin options give patients who can’t tolerate statins real alternatives.
Lp(a) — What It Is and What to Do With It
Lipoprotein(a) is a genetically driven particle that accelerates plaque formation, promotes inflammation, and makes blood more likely to clot.
It is not modifiable by lifestyle, and statins actually raise it slightly — the LDL remains the primary therapeutic target.
A very high Lp(a) combined with a strong family history of early heart disease is a red flag that should sharpen clinical decision-making across the board.
Drugs to directly lower Lp(a) are in late-stage trials and look promising, but aren’t yet on the market.
Exercise, Diet, and the Case Against Prescriptive Protocols
The best exercise is the one you’ll actually do — movement matters more than which movement.
Strength training is especially important in midlife to preserve muscle mass, but the barriers are real; YouTube body weight workouts are a legitimate starting point.
Most people know what junk food is; the best dietary strategy is the one that fits your actual life — and only a real conversation reveals which approach will stick.
Upshot
The new cholesterol guidelines are a useful framework — not a personal prescription. Whether the question is statins, calcium scores, or Lp(a), the answer almost always depends on who you are, what your family history looks like, and what you’re willing to do. Numbers need context, and good medicine means treating the human behind the chart.
