In this episode, Erin discusses current trends in cardiovascular disease (CVD) through the lens of female biology and the observation that major adverse cardiac events in both sexes are on the rise. She walks through risk factors including LDL-cholesterol, apoB, and Lp(a) and makes the case for the importance of early preventative measures. She explains various interventions for reducing risk including a discussion of statins, GLP-1 agonists, PCSK9-inhibitors, and drugs that lower Lp(a). She goes in-depth on female-specific factors that contribute to CVD risk such as pregnancy, grand multiparity (having five or more children), oral contraceptives, menopause, and polycystic ovary syndrome (PCOS). Additionally, she explains her approach with patients as it relates to the use of hormone replacement therapy and provides advice for people wanting to lower risk both through lifestyle changes & medications. 0:00:00 - Intro 0:02:30 - Erin’s background in preventive cardiology 0:05:15 - Recent trends in cardiovascular disease in women, mortality data, & how it compares to cancer 0:13:15 - Why early preventative measures are critical for CVD risk 0:19:45 - ApoB as a causal agent of CVD, & why high apoB levels are not being aggressively treated 0:27:00 - The rising trend of metabolic syndrome & other factors contributing to the regression in progress of reducing cardiac events 0:33:30 - GLP-1 agonists—Promising drugs for diabetes & obesity 0:37:15 - Female-specific risk factors for ASCVD 0:47:00 - Polycystic ovary syndrome (PCOS): prevalence, etiology, & impact on metabolic health, lipids & fertility 0:52:30 - The effect of grand multiparity (having 5+ children) on cardiovascular disease risk for women 0:55:00 - The impact of oral contraceptives on cardiovascular disease risk 0:58:45 - The effect of pregnancy on lipids & other metabolic parameters 1:02:00 - The undertreatment of women with familial hypercholesterolemia (FH) & how it increases lifetime risk of ASCVD 1:09:45 - How concerns around statins have contributed to undertreatment, & whether women should stop statins during pregnancy 1:16:00 - How Erin approaches the prescription of statins to patients 1:21:15 - PCSK9 inhibitors & other non-statin drugs 1:28:30 - Advice for the low- and high-risk individual 1:31:00 - The impact of nutrition, stress, & lifestyle on lipids & CVD risk 1:41:15 - Lp(a) as a risk enhancer for cardiovascular disease 1:50:30 - The effect of menopause on cardiovascular disease risk 1:55:30 - How Erin approaches decisions regarding hormone replacement therapy (HRT) for her patients 2:03:30 - The urgent need for more data on women’s health 2:09:45 - Erin’s goal of running a marathon in every state -------- About: The Peter Attia Drive is a weekly, ultra-deep-dive podcast focusing on maximizing health, longevity, critical thinking…and a few other things. With over 45 million episodes downloaded, it features topics including fasting, ketosis, Alzheimer’s disease, cancer, mental health, and much more. Peter is a physician focusing on the applied science of longevity. His practice deals extensively with nutritional interventions, exercise physiology, sleep physiology, emotional and mental health, and pharmacology to increase lifespan (delay the onset of chronic disease), while simultaneously improving healthspan (quality of life).

WHAT IT’S REALLY ABOUT

Women's Heart Disease: Early Prevention, Lipids, Pregnancy, Statins, Menopause and Trial Gaps

  1. Michos reports that cardiovascular mortality declines have stalled and are rising in younger and middle-aged women, driven by obesity, diabetes, and cardiometabolic disease, while many women still fear cancer more than heart disease.
  2. Both speakers argue that lifetime exposure to LDL/apoB matters more than 10-year risk scores, so treating earlier, particularly in younger adults and in women with familial hypercholesterolemia, is warranted.
  3. The conversation walks through female-specific factors including menstrual cycle lipid shifts, PCOS, parity, oral contraceptives, pregnancy, and the lipid and androgen changes of menopause.
  4. Michos explains that women benefit from statins as much as men but are less likely to be offered them and more likely to stop them, and she outlines her approach with statins, PCSK9 inhibitors, inclisiran, bempedoic acid, and Lp(a) therapies.
  5. They discuss menopausal hormone therapy as a symptom-driven choice rather than a heart-prevention tool, and Michos calls for more women in cardiovascular trials and trial leadership.

IDEAS WORTH REMEMBERING

5 ideas

Heart disease progress has stalled and is reversing in some groups of women.

Michos says mortality is rising in younger women and fastest in women aged 45 to 64, and that heart disease may overtake cancer as the leading cause of death in younger women if trends continue.

Time exposure to LDL/apoB should drive treatment decisions, not just 10-year risk.

Both speakers argue that 10-year scores are dominated by age and ignore a causal agent. Michos tells patients she wants to prevent heart attacks over the next 40 years, not only the next 10.

Women are not protected from heart disease if they have FH, diabetes, or smoke.

The usual roughly 10-year female delay in ASCVD does not appear in FH, where women have the same early onset as men. Michos says about 30% of women with untreated FH will have a heart attack before 60.

Statins work in women, but women are undertreated.

Michos cites meta-analyses showing similar benefit by sex, yet women are less likely to be offered statins and more likely to decline or stop them, partly because of muscle symptoms and a large nocebo effect.

Pregnancy temporarily raises lipids and statin guidance is shifting.

Cholesterol, triglycerides, and LDL rise in pregnancy and fall afterward, and Michos still generally stops statins around conception and pregnancy. She notes the FDA removed its strongest warning, and a trial is testing pravastatin for preeclampsia prevention.

WORDS WORTH SAVING

5 quotes

It's never too late to implement prevention, but prevention is better implemented when started earlier.

— Erin Michos

I'm not just concerned about preventing a heart attack in the next 10 years. I want to prevent them from having a heart attack over the next 40 years.

— Erin Michos

You know, the really how we live the first half of our lives really influences our freedom from morbidity and mortality the second half of our lives.

— Erin Michos

You don't have to be good at a hobby to enjoy it.

— Erin Michos

It's basically a peashooter in a bazooka fight when we have big, big guns to reduce the risk of cardiovascular disease.
