Nathaniel R. Smilowitz, MD

As an interventional cardiologist at NYU Langone, I am dedicated to providing thoughtful, compassionate, and high-quality care to my patients. I find immense gratification in helping individuals feel better, improving their quality of life, and enabling them to return to the activities they love. My approach to patient care is deeply rooted in a calm demeanor and a commitment to understanding each patient’s unique needs.

I specialize in diagnosing and treating patients with chest pain, particularly those with blocked heart arteries. Using advanced techniques such as balloons and stents, I work to restore blood flow to the heart muscle, significantly enhancing my patients’ wellbeing.

Additionally, I have a keen interest in managing chest pain that occurs without significant blockages in the coronary arteries. This often involves conditions like coronary microvascular dysfunction, which affects the small blood vessels in the heart, and coronary spasm, which is a temporary narrowing of the heart’s blood vessels. These conditions require specialized testing in the catheterization laboratory for accurate diagnosis.

Throughout my career, I have focused on advancing the field of cardiology so patients can benefit from the latest advancements. My clinical research aims to uncover the causes of coronary microvascular dysfunction and coronary spasm, and to develop new diagnostic and treatment approaches for these often-overlooked conditions.

My journey into medicine was inspired by a desire to make a meaningful impact on my patients’ lives. I am privileged to be part of NYU Langone, where I not only care for patients but also contribute to advancing medical science and the training of future physician leaders.
