Tamar Polonsky, MD, MSCI, is a general cardiologist who treats a wide range of cardiac conditions, including coronary artery disease, hypertension, hyperlipidemia (high cholesterol) and valve disease.
Dr. Polonsky also specializes in the management of heart disease in cancer patients (cardio-oncology). She works closely with oncologists and surgeons to take care of patients with preexisting heart disease and to help monitor for potential cardiac complications from chemotherapy and radiation.
Dr. Polonsky has research expertise in cardiovascular epidemiology and prevention. She has experience analyzing data from large cohort studies, with the aim of finding novel ways to predict a person's risk of developing heart disease.
