Two decades in cardiology and the electrophysiology lab, now focused on what drives heart disease in the first place: metabolic health, inflammation, lifestyle, and the gut. Telehealth consults and second opinions, nationally and internationally.
A mechanism-minded cardiologist who kept finding the real problem upstream.
Andrew Rudin, MD is a cardiologist and board-certified cardiac electrophysiologist with more than twenty years of experience. For much of his career he treated the heart the way electrophysiologists are trained to — mapping and ablating the tiny circuits behind dangerous rhythms, with thousands of procedures in the EP lab. But over time he became just as interested in the causes sitting underneath heart disease as in the rhythms on the monitor.
Today he practices a natural, root-cause approach: addressing diet, metabolic health, inflammation, sleep, stress, and — increasingly — the gut microbiome, which he considers one of the most overlooked drivers of cardiovascular and whole-body health. He sees patients nationally and internationally through telehealth via Natural Heart Doctor — including across Europe, Canada, Mexico, and Australia — often for second opinions before major procedures, and writes for patients in plain language about the evidence behind everyday heart decisions.
Rigorous conventional training — applied to a root-cause philosophy.
Treat the fire, not just the smoke.
High cholesterol, high blood pressure, and arrhythmias are often symptoms of something upstream. I look for the real drivers — insulin resistance, inflammation, diet, sleep, and stress — and work on those.
The microbiome shapes blood pressure, cholesterol particles, and inflammation. Supporting the right gut environment is becoming one of the most promising frontiers in preventive cardiology.
Before an ablation, a stent, or a new prescription, a careful second look can change the plan. I help patients walk into big decisions fully informed.
I explain the evidence — including where it's weaker than patients are told — so you can make decisions that fit your life, alongside your own physician.
Sought out as an expert source on heart health.
In their own words.
“As an electrophysiologist, his level of expertise is outstanding — but what truly sets him apart is his openness to integrative and natural approaches to heart health. He took the time to truly listen. If you're looking for a great electrophysiologist for a second opinion, he's your guy!”
“Even though he wasn't the primary doctor, he monitored my father's chart daily, noticed the team was missing steps, and stepped in. His diligence quite literally saved my dad's life. He treated us like family.”
“He sent detailed instructions and answered every follow-up question. My triglycerides went from 224 to 100 with no pharmaceuticals, and my HDL improved too.”
