Philosophy of Care
Dr. Schaefer views each patient as an individual, and is interested in their approach to their health. He works with patients to optimize their health and uses the full range of therapies to treat cardiovascular disease.
Dr. Schaefer is a general cardiologist offering care to patients with, or at risk for, cardiovascular disease. He has a special interest in disease prevention, emphasizing non-pharmacologic approaches to heart disease. He has a special interest in abnormalities of lipid metabolism, including diagnosis and treatment of high cholesterol.
Dr. Schaefer has an active laboratory studying how to prevent and treat heart failure. Using a genetically modified mouse model, Dr. Schaefer is trying to understand the metabolic abnormalities that are seen in heart failure. He is using that knowledge to develop new and unique treatments that could be used in patients with, or at risk for, heart failure.
