Physician, Associate Professor
Cardiovascular Disease
Department: Internal Medicine
As a cardiologist, I work closely with my patients to formulate individualized care plans with special consideration for their cardiovascular health. I treat numerous heart conditions including but not limited to adult cardiology, coronary artery disease, hypertension, hypercholesterolemia, and cardiac disorders of neuromuscular disease. It’s important for my patients to be actively involved in their own care, so I encourage them to ask questions and stay involved. I begin the process of treatment by addressing any concerns that my patients or their families may have before conducting a thorough evaluation of their cardiovascular health.
I specialize in cardiac MRI, and I am the program director of the Cardiovascular Diagnostic Imaging Fellowship-Training Program. Together with the neuromuscular team, I helped establish the Multidisciplinary Cardiopulmonary Neuromuscular Clinic in 2026. My research focuses on using cardiac MRI to improve cardiovascular disease diagnosis and treatment.
What I love most about The Ohio State University Wexner Medical Center is the opportunity to work with a talented and dedicated team to advance patient care through clinical and research endeavors.
When I'm not working, I enjoy spending time with my son and my husband, gardening and cooking.

Very attentive and thorough (both Dr. Zarega and the resident). The nurse who administered the EKG and holter monitor also excellent.
Outstanding- best physician encounter I have ever had
Great care always.
The dr was very informative and helpful
Professional, experienced, caring
The doctor was excellent.
This was my first visit with this cardiologist (who replaced my previous cardiologist who'd moved) and she was well-prepared. Again, everything was business-like, but friendly.
excellent doctor; listens to issues, and explains everything clearly to me.. Keeps up-to-date on my medical statistics.
My care provider is very personable. She is in the here and now during the appointment. She explains things clearly.
Dr Zareba spends time with me and I feel she listens to my questions/concerns.I've been with OSU for many years and two of my doctors have moved on. I really hope Dr Zareba loves Columbus and stays put.
My care provider was wonderful. Although I was a new patient establishing under her care, she thoroughly analyzed my medical records before coming in to meet with me. She even provided me with a printed exercise program to help manage an existing condition and showed great concern for my health.
As always, a wonderful lady who takes her time to ask questions and talk about any concerns I may have.
Dr Zareba is an outstanding doctor. She is very thorough and detailed in our discussions. I am thankful she is my cardiologist.
Good - Dr. Zareba is competent, thorough, a great listener, and is always willing to invest whatever time I need to ask any questions and reach closure with me on the answer.

D. Zareba is a valued member of my health care team!
Dr. Zareba is OUTSTANDING. She took so much time with me to explain answers to all of my questions about starting a statin. She even pulled up online research to support her answers and gave me time to scan the information to ease my concerns. I've also used OSU MyChart to ask questions during my treatment journey and Dr. Zareba is EXTREMELY prompt, thorough, and helpful with her responses! She even addressed one of my concerns by calling me to speak in person about my question while she was on her family vacation. That is BEYOND outstanding care!
The experience was all good the staff and Dr. Were very kind and efficient!
I was very happy with the time spent with me and how things were explained.
Dr z is an amazing doctor! She is respectful responsible extremely thorough extremely knowledgeable especially about my specific needs and medical situation and she looks at all angles and avenues that affect it and how to treat it best. I am extremely pleased with her as a doctor I do not think I have seen as many doctors as good as her in my life experience. I highly recommend her to anyone and hope she's six round long enough that I can stay with her for many years.
