The ReplyRecently, we proposed a new internal medicine subspecialty−Cardiometabolic Medicine. 1 While we received a great deal of positive feedback−from clinicians, health systems, NIH program officers, journal publishers, and industry−we also received several critiques. A prominent concern raised by Dr. Doroghazi pertains to length of training. This is an important issue, which we agree represents a major problem in modern medicine.First, we would like to clarify our proposed training pathway. We envision a three-year training program following internal medicine residency. This is one year longer than endocrinology fellowship and is commensurate or shorter than many cardiology fellowships (which are 3-4 years). Perhaps most importantly, a career pathway in Cardiometabolic Medicine would be at least one year shorter than the current training for preventive cardiology, which requires at least one additional year after general cardiology fellowship. 2 We see Cardiometabolic Medicine as a streamlined curriculum that would otherwise require rotations in many disparate fields: endocrinology, cardiology, nephrology, hepatology, and obesity medicine for example. In 2020, there is no way for a trainee interested in this field to obtain the necessary training with any less than 4 years after Internal Medicine residency, and even so this would require tremendous individual planning.While shortening college or medical school remains a separate issue worth discussing, 3 we believe that a new Cardiometabolic specialty could be time-saving for many. 4 Of note, we have received the opposite feedback as well − how could you learn critical aspects of endocrinology, metabolism, cardiology, and atherosclerosis imaging in just 3 years?We are certain it could be done, and that it should be done.
