Medscape Reference and St. Luke's-Roosevelt Hospital Center have formed a partnership to develop content covering key areas of medicine, including critical care, clinical procedures, and electrophysiology. The content reviews the essentials of these subjects but also features insights from key thought leaders affiliated with the medical school and, specifically, the Departments of Internal Medicine, Emergency Medicine, and Cardiology. These leading physicians and surgeons offer their perspective on the comparative effectiveness of different surgical approaches, developing technology, and new recommendations for care of patients. Selected contributions are featured on this page.
