Dr. Joel Kahn discusses heart health assessments, emphasizing that feeling good is not enough to ensure a healthy heart. He recommends a coronary artery calcium CT scan, ideally aiming for a score of zero, which indicates no calcified plaque. If the score is not zero, lifestyle changes are necessary. For a more comprehensive view, a CT angiogram can be performed, though it is not the first test to consider.
Kahn highlights the importance of blood tests, particularly hemoglobin A1c for blood sugar levels, fasting insulin, hsCRP for inflammation, and lipoprotein little a (LP(a)), a genetic cholesterol that can be harmful. He also mentions APO lipoprotein B (APO B), which aggregates all bad cholesterol particles into one number, helping to assess cardiovascular risk.
He stresses the significance of lifestyle factors such as diet, sleep, and exercise in managing heart health. Kahn advocates for a whole food, plant-based diet, while acknowledging that individuals can have varying dietary needs. He notes that high LDL cholesterol levels can exist alongside good metabolic health, underscoring the need for personalized assessments.
Kahn also discusses the role of supplements, particularly aged garlic extract and a product called Arterial Protect, which contains Gotu Kola and Pycnogenol, both shown to reduce plaque. He cautions against high doses of vitamin K2, as recent studies show no significant impact on calcium scores.
The conversation touches on the importance of strength training and adequate protein intake for muscle mass and metabolic health. Kahn references Dr. Walter Longo's research advocating for lower protein intake for longevity, suggesting a balanced approach to diet and exercise.
Finally, Kahn emphasizes the need for proactive heart disease screening, particularly for high-risk populations like South Asians, and encourages individuals to seek personalized medical advice to ensure optimal heart health.
