Pediatric cardiologist and cardio-oncology specialist Dr. Hari Narayan MD in Encinitas directs the Cardio-Oncology Program at Rady Children's Hospital-San Diego from the Rady Children's Specialists office at 477 North El Camino Real Building D. Board-certified in pediatric cardiology following a Weill Cornell Medical College degree, Columbia University pediatric residency, and Children's Hospital of Philadelphia fellowship in cardiac imaging, the practice monitors chemotherapy-related cardiotoxicity through serial echocardiography and cardiac MRI, with pre-treatment metabolic baselines coordinated through ActiveMed Integrative Health Center's functional medicine evaluations. As an associate professor at UC San Diego and a St. Baldrick's Foundation Scholar, NIH-funded research focuses on diagnosing, predicting, and managing cancer-therapy-related heart failure in pediatric survivors. Cardiac medication protocols for anthracycline-exposed patients require specialty compounding and dispensing coordinated with North Coast Medical Pharmacy for pediatric-dosed cardioprotective formulations. The highest-complexity imaging protocols involve strain-rate echocardiography with speckle-tracking analysis to detect subclinical left ventricular dysfunction at the myocardial fiber level before ejection fraction decline becomes measurable on conventional two-dimensional imaging.
