Preventing the 4 Horseman of Death

Last month we discussed Peter Attia’s 4 common causes of death.

Here are two videos where Dr. Attia discusses prevention (one and two)

I’m sure there will be advancements in the future. And these interventions need to be individualized. But this provides some good information for all.

1. Atherosclerotic Cardiovascular Disease (ASCVD) Prevention:

ASCVD is presented as a disease with clear pathways for prevention, making it arguably the most preventable of the four.

  • Lowering ApoB Particles:

    • What it is: ApoB is a protein that's part of lipoproteins (like LDL, VLDL) that carry cholesterol in the blood.A high number of ApoB particles means more of these potentially artery-clogging particles are present.

    • Prevention Focus: The primary goal here is to reduce the number of these particles. This often involves:

      • Dietary interventions: Reducing saturated and trans fats, increasing fiber, and adopting heart-healthy eating patterns (e.g., Mediterranean diet).

      • Exercise: Regular physical activity can positively impact lipid profiles.

      • Medication (if necessary): Statins are often used to effectively lower ApoB and LDL cholesterol when lifestyle alone isn't sufficient.

  • Protecting the Endothelium:

    • What it is: The endothelium is the delicate inner lining of your blood vessels. Damage to this lining is an early step in plaque formation.

    • Prevention Focus: Avoid factors that damage the endothelium:

      • Stop smoking: Smoking is a major endothelial toxin.

      • Manage blood pressure: High blood pressure puts mechanical stress on the endothelium. Regular exercise, a low-sodium diet, and potentially medication are key.

      • Address metabolic conditions: Insulin resistance, high glucose, and high insulin levels (often part of metabolic syndrome) directly harm the endothelium. This ties into metabolic disease prevention.

  • Managing Inflammation:

    • What it is: Chronic low-grade inflammation plays a significant role in the progression of ASCVD.

    • Prevention Focus: While direct pharmacological treatments for inflammation in ASCVD are limited, broad lifestyle changes are highly effective:

      • Nutrition: An anti-inflammatory diet rich in fruits, vegetables, whole grains, and healthy fats (like omega-3s).

      • Sleep: Adequate, quality sleep is crucial for regulating inflammatory processes.

      • Exercise: Regular physical activity has systemic anti-inflammatory effects.

2. Cancer Prevention:

The video suggests that while prevention is more challenging for cancer due to the role of "bad luck" (somatic mutations), there are still significant environmental factors to address.

  • Addressing Environmental Triggers:

    • Smoking Cessation: This remains one of the most impactful prevention strategies for a wide range of cancers.

    • Obesity Management: Obesity is strongly linked to several cancers, likely due to chronic inflammation, hormonal imbalances (e.g., high insulin, IGF-1), and altered metabolism.

      • Diet and Exercise: Maintaining a healthy weight through balanced nutrition and regular physical activity is critical. Physical therapists can assist with exercise programs tailored for weight management.

  • Dietary Considerations:

    • The video notes that evidence linking specific foods to cancer is less clear when diets are isocaloric (same calorie intake), suggesting that overall calorie balance and avoiding obesity are more crucial than obsessing over individual foods.

  • Early and Aggressive Screening:

    • Given the limitations in direct prevention for all cancers, early detection through recommended screenings (e.g., mammograms, colonoscopies, PSA tests) is emphasized as a vital strategy for improving outcomes.

3. Neurodegenerative Diseases (e.g., Alzheimer's) Prevention:

Prevention for neurodegenerative diseases is highlighted as being "in the middle ground" – not as clear-cut as ASCVD, but with significant potential.

  • "What's Good for the Heart is Good for the Brain":

    • Interventions that lower ASCVD risk also reduce dementia risk:

      • Better metabolic health: Managing blood sugar, insulin sensitivity, and weight reduces systemic inflammation and vascular damage that can affect the brain.

      • Lower ApoB: Directly related to better vascular health in the brain.

      • Lower blood pressure: Chronic hypertension damages small blood vessels in the brain, contributing to cognitive decline.

      • Not smoking: Protects brain vasculature and overall brain health.

  • Exercise for Greater Benefits:

    • While exercise is good for the heart, the video suggests its benefits for preventing neurodegenerative diseases might be even more pronounced.

    • Mechanisms: Exercise improves blood flow to the brain, promotes neurogenesis (growth of new brain cells), reduces inflammation, and enhances brain plasticity. Physical therapy is crucial here, helping individuals maintain or improve their physical activity levels safely and effectively.

  • Building Cognitive and Movement Reserve:

    • Cognitive Reserve: Engaging in mentally stimulating activities (learning new skills, reading, puzzles) builds a more robust neural network, which can help the brain compensate for damage later in life.

    • Movement Reserve: Maintaining physical function, balance, and mobility through consistent exercise and activity helps maintain brain health and reduce the risk of falls, which can also impact cognitive health.

4. Metabolic Diseases Prevention:

Metabolic diseases are presented as having a clear mechanistic understanding and being largely preventable. They are also critical because they significantly increase the risk of the other three "horsemen."

  • Addressing Overnutrition and Energy Imbalance:

    • Primary Driver: These diseases (e.g., fatty liver disease, type 2 diabetes, insulin resistance) are fundamentally driven by consuming more calories than are expended, leading to excess fat storage and insulin resistance.

    • Prevention Focus:

      • Dietary Quality and Quantity: Focusing on whole, unprocessed foods, managing portion sizes, and reducing intake of refined sugars and unhealthy fats.  Dr. Attia's research suggests that lifestyle changes like low-carbohydrate diets and intermittent fasting can improve metabolic healt

      • Regular Physical Activity: Exercise plays a vital role in improving insulin sensitivity, burning calories, and maintaining a healthy body composition. Physical therapists can help design appropriate exercise programs.

      • Weight Management: Achieving and maintaining a healthy weight is paramount.

Summary

The video underscores a proactive, preventative approach, heavily reliant on lifestyle modifications.For physical therapy, this means emphasizing:

  • Prescribing exercise tailored to individual needs, addressing cardiovascular health, metabolic health, and cognitive function.

  • Educating patients on the importance of physical activity for overall health and disease prevention.

  • Collaborating with other healthcare professionals to ensure comprehensive care that addresses nutrition, sleep, and stress management.

By focusing on these core areas, individuals can significantly reduce their risk of succumbing to the "four horsemen of death."
