Episode: Woman Heart Attack Signs & Menopause Risk Explained

Host: Louisa Nicola (with Pursuit Network)

Guest: Dr. Jeremy London, Cardiac Surgeon

Release Date: July 24, 2025

Episode Overview

In this insightful episode, Louisa Nicola sits down with renowned cardiac surgeon Dr. Jeremy London to unpack the gender-specific risks of heart disease, focusing on how menopause dramatically increases women’s cardiovascular risk and what can be done to mitigate it. The conversation ranges from foundational science—why women’s risk triples after menopause—to practical, actionable advice on monitoring heart health, interpreting biomarkers, and leveraging lifestyle interventions. The episode also touches on evolving diagnostics, the impact of COVID-19 on cardiovascular health, and the future role of AI in medicine.

Louisa and Dr. London’s dynamic exchange is rich in clinical knowledge, personal anecdotes, and memorable quotes that make this essential listening for anyone interested in heart and brain health—especially women concerned about midlife risk changes.

Key Discussion Points and Insights

1. Why Women’s Heart Disease Risk Triples After Menopause

(00:00–04:28)

• Historical Gender Bias in Research:
  Dr. London highlights the late inclusion of women in cardiovascular studies, noting, "Women have not been included in many of these cardiovascular studies till the early 90s, which is unbelievable to me." (00:04).

• Role of Estrogen:
  As estrogen falls during perimenopause and menopause, full-body inflammation increases—a core driver of chronic disease, including cardiovascular conditions.

  • Estrogen functions as an anti-inflammatory; its decline intensifies risk factors like weight gain (particularly visceral fat) and higher LDL cholesterol.
  • “It's almost like a perfect storm … For some women, hormone replacement therapy can make a dramatic difference … and help mitigate risk.” – Dr. London (02:39)

• Cholesterol and Metabolic Shifts:
  LDL (“bad” cholesterol) rises as estrogen drops: “As estrogen levels drop, cholesterol levels rise in perimenopause and menopause.” – Dr. London (02:55)

2. Connection of Menopause, Alzheimer’s Disease and Heart Health

(03:40–04:28)

• Estrogen receptors are present all over the heart and brain; loss of estrogen removes neuroprotection:
  • “When that lock has nothing to attach to, it becomes scary … It's also neuroprotective, that hormone as well.” – Louisa (03:55)

3. Defining and Interpreting the Lipid Panel

(04:28–10:15)

• Total Cholesterol is Misleading:
  • Critical to break down HDL, LDL, and triglycerides, as each offers different insights.
  • “Anyone can take your blood. It’s about who’s interpreting it … are you trending upwards?” – Louisa (08:51)
• ApoB as the Best Risk Measure:
  • “I look at it as a 25,000-foot view of all cholesterol subgroups … If your overall ApoB is low, you fall in a lower risk.” – Dr. London (09:17)
• LP(a): The Hereditary Wildcard:
  • Lipoprotein(a) [“LP little a”] is highly genetic and not modifiable.
  • “You can’t lower this number … get this test once in your life, because it'll always be the same.” – Louisa (12:21)

4. Heart Imaging: How to Assess Your True Risk

(15:05–20:57)

• Calcium Scoring CT (CAC Score):
  • Fast, non-invasive, helps “screen for risk” (15:41).
  • Zero score is reassuring even with high LP(a); high scores call for more investigation.
• Cardiac Catheterization:
  • Gold standard if CAC questionable/high.
  • Now predominantly done through the wrist, decreasing complications: “90% of cases are done through the wrist … Patients can be discharged very quickly.” – Dr. London (18:51)
• Carotid Ultrasound for Brain Arteries:
  • Especially important in seniors or those at elevated risk.
  • Zero radiation and a valuable yearly baseline.

5. Atrial Fibrillation & Stroke: Hidden Dangers

(21:44–29:00)

• Atrial Fibrillation = High Lifetime Stroke Risk:
  • “There’s a 20% lifetime risk of stroke with atrial fibrillation … which is why patients have to be on blood thinners.” – Dr. London (24:10)
  • Diagnosis can be tricky—intermittent arrhythmias often missed by standard ECGs; wearables and Holter monitors becoming vital.
• Symptoms and Self-Awareness:
  • “Start with being aware of your body first … Anxious feeling, shortness of breath, fluttering in the chest.” – Dr. London (27:01)
  • Use wearables intelligently but trust bodily cues.

6. The COVID-19 Cardio Aftermath

(31:57–35:45)

• Worsening Inflammatory Responses:
  • “[COVID-19] patients with baseline coronary disease … did very, very poorly with bypass surgery and stenting, again probably from this overall inflammatory response.” – Dr. London (33:15)
• Surge in Cardiomyopathies Among Young People:
  • “Echocardiograms would show ejection fractions of 20, 25%. Yes, it was really dramatic. Again, the thought process was that it was almost like an autoimmune situation.” – Dr. London (34:40)

7. Blood Pressure—Why the Numbers Matter More than You Think

(35:45–41:41)

• SPRINT Trial Takeaway:
  • Even small rises above 120/80 cause harm at the capillary level.
  • “Just a small change in blood pressure can have a dramatic impact, particularly at the capillary level.” – Dr. London (36:53)
• Home Monitoring Tips:
  • Routine, calm, correct procedure is vital for accurate blood pressure readings.

8. Diet, Lifestyle, and the Non-Pharmacological “Pillars” of Heart Health

(48:06–60:01)

a. Exercise

• Dr. Ben Levine’s research showed two years of intense exercise can “turn a 50-year-old’s heart into a 30-year-old’s heart.” – Louisa (49:00)
• “VO2 max is probably one of the single most important indicators of longevity that we have.” – Dr. London (50:25)
• Resistance training is critical for muscle mass, which is “the organ of longevity.” (51:36)

b. Diet

• “90% of the outside world is through our body. And we literally are made of what we eat.” – Dr. London (53:29)
• Focus on whole foods, limiting processed foods, and alcohol.
• Exercise alone can't compensate for poor diet.

c. Sleep

• “Sleep is my personal Achilles heel … True growth, whether it’s our mental muscle or our physical muscle, occurs during sleep.” – Dr. London (57:03)

d. Consistency & Customization

• “Of these pillars of health, figure out which one you don’t do well, because that’s the one that’s most important for you.” – Dr. London (60:01)

9. AI and the Future of Cardiac Medicine

(41:41–46:44)

• AI-Enhanced Diagnostics:
  • “I think that AI is going to be transformative in medicine … It’s going to pick up on subtleties that we as human beings miss.” – Dr. London (43:20)
• Real-world AI Success Story:
  • “He took all of the physical findings … and put them into Open Evidence and it gave him the diagnosis. … The patient actually got better.” – Dr. London (45:24)
• AI is not yet replacing surgeons but is revolutionizing diagnostics and research efficiency.

Notable Quotes & Memorable Moments

• On Female Risk Post-Menopause:
  • “As estrogen levels drop, cholesterol levels rise … It’s almost like a perfect storm.” – Dr. London (02:55)
• On Diagnostics:
  • “ApoB is very important because as you said, the panel kind of paints the broad brush strokes. Now we want to look at what those numbers truly mean.” – Dr. London (09:36)
• On Wearables:
  • “The wearable devices are really good at picking up irregular heart rate, so that’s a great place to start.” – Dr. London (27:34)
• On Lifestyle Change:
  • “You’re not defined by your past. … Small steps, because all those small steps compound to really get you where you want to be.” – Dr. London (56:24)
• On holistic health:
  • “What’s good for the heart is good for the brain. This is why this has been such a beautiful podcast today.” – Louisa (60:37)

• Screening tests (CAC, carotid ultrasound) are crucial for baseline risk, especially for those with genetic factors.
• Lifestyle factors—especially exercise, diet, and sleep—are powerful levers for prevention, but consistency and targeting your weakest pillar is key.
• AI is rapidly reshaping diagnostics but clinical judgment remains irreplaceable—at least for now.
• Knowledge, vigilance, and advocacy (especially for women who may be dismissed) are crucial in the early detection and management of heart disease.
