About me

Dr. Orest B. Bartoszyk, MD, is an attending cardiologist and Director of the Professional Education Committee at MedStar St. Mary’s Hospital. The majority of his patients suffer from coronary artery disease, congestive heart failure, atrial fibrillation, hyperlipidemia, or hypertension.

Working closely with his patients, Dr. Bartoszyk aims to formulate a good rapport so that together, they can collaborate in determining lifestyle changes to reduce cardiovascular risk factors. As part of this approach, he recommends stress reduction through lifestyle modification and the use of non-medicinal strategies. He also stresses optimizing nutrition to lower blood pressure, reduce lipid levels, and improve glycemic control through food choice. Dr. Bartoszyk’s specialty is in echocardiography, including transesophageal echocardiography (TEE), an imaging technology that allows him to better understand and treat a patient’s existing cardiac condition.

Dr. Bartoszyk’s passion for cardiology was born when he began reading EKGs at age 18, while volunteering during the summer with the Department of Cardiology at St. Michael’s Medical Center in Newark, New Jersey. He then went on to participate in the Beta Beta Beta (TriBeta) Biological Honors Society and Phi Beta Kappa Honors Society at Rutgers University (Newark College of Arts and Science) from where he graduated Summa Cum Laude. He obtained his medical degree from the University of Medicine and Dentistry of New Jersey at Newark. Dr. Bartoszyk completed his residency training at the University of Medicine and Dentistry of New Jersey, the Newark Beth Israel Medical Center, and the East Orange General Hospital, followed by cardiology fellowship training at St. Michael’s Medical Center.
