We had the privilege of sitting down with Dr. Kenji Chen, a leading cardiologist and researcher at the forefront of preventative heart care. With over two decades of experience, Dr. Chen’s work is changing how we approach cardiovascular wellness. In this interview, we discuss the biggest misconceptions about heart disease, the role of technology, and the simple changes that can make the biggest difference.
HealthHub: Dr. Chen, thank you for joining us. What is the single biggest myth about heart health you wish you could dispel?
Dr. Chen: The most pervasive myth is that heart disease is primarily a man’s problem, and one that only affects the elderly. This is dangerously untrue. Heart disease is the leading killer of women, and the warning signs can be far more subtle. Furthermore, we are seeing the foundations of heart disease being laid down earlier and earlier in life due to diet and lifestyle. The conversation about heart health needs to start in your 20s and 30s, not your 50s and 60s.
“The simplest lifestyle changes often have the most profound impact on heart health. It starts with your plate and your feet.”
HealthHub: You mention lifestyle. Beyond “eat less, move more,” what is the most impactful, actionable advice you give your patients?
Dr. Chen: It’s to understand that consistency trumps intensity. I’d rather a patient walks for 30 minutes every single day than goes to the gym for two hours once a week. It’s about building sustainable habits. For diet, my advice is simple: add, don’t just subtract. Instead of focusing on what to eliminate, focus on adding more vegetables, more fiber, and more whole foods to every meal. The bad stuff tends to get crowded out naturally. It’s a psychological shift that makes healthy eating feel like an act of abundance, not deprivation.
HealthHub: How is technology changing cardiology? Are things like smartwatches and wearable sensors making a real difference?
Dr. Chen: Immensely. Wearable technology is a double-edged sword, but its potential is undeniable. For many, it provides incredible real-time data that empowers them to be more engaged with their health. The ability to track heart rate, activity levels, and even perform a basic ECG is revolutionary for early detection of conditions like atrial fibrillation. The challenge for us as clinicians is to help patients interpret this data correctly and not fall into a trap of health anxiety. It’s a tool, not a doctor. But it’s a very, very powerful tool.
HealthHub: Finally, what are you most optimistic about for the future of heart health?
Dr. Chen: I’m most excited by the advancements in preventative and personalized medicine. We’re moving beyond treating the symptoms of heart disease and getting better at identifying and managing risk factors at a genetic level. We can now tell patients with a high degree of certainty what their specific risks are and provide truly tailored advice. This proactive, personalized approach is the future, and it will save countless lives.
