Dr. Mozaffarian's primary research interests are lifestyle factors and prevention of cardiovascular disease. He is particularly interested in effects of dietary habits, incuding fish and omega-3 fatty acids and trans fatty acids, on cardiovascular health. His training in cardiology, epidemiology, and nutrition facilitates an integrated approach to formulating research hypotheses and the methods to address these questions. A translational approach also allows application of clinical experiences to research questions and of research results to patient care. To understand more fully the public health and cardiovascular impact of diet, Dr. Mozaffarian is interested in the effects on multiple cardiovascular outcomes, including coronary heart disease, sudden death, stroke, heart failure, and atrial fibrillation. He is also interested in potential intermediary phenotypes, pathways, and risk factors, such as hemodynamics, inflammation, cardiac structure and function, and electrophysiology.
