Andrew Y. Chang, MD, PhD

Andrew Y. Chang, MD, PhD, is a cardiologist who specializes in cardiovascular medicine and cardiac imaging. He provides care for patients with a variety of heart conditions, using advanced techniques such as echocardiography, which is an ultrasound-based method to visualize the structure and function of the heart. Dr. Chang has particular expertise in guiding minimally invasive procedures to repair or replace heart valves using real-time imaging, reducing the need for open-heart surgery.

As an assistant professor of medicine at Yale School of Medicine, Dr. Chang’s research explores how environmental factors—including climate change—affect heart health. He investigates ways to use digital data, such as information collected from electronic health records and wearable devices, to identify harmful environmental exposures and develop strategies to reduce their impact on cardiovascular health.

Dr. Chang earned his medical and doctoral degrees from Stanford University, where he also completed his internal medicine residency, chief residency, and a fellowship in cardiology. He then completed advanced fellowship training in echocardiography at the University of California San Francisco.
