I have several questions about cardiology. -First of what percentage of cardiologists are hospitalists? -Which types of of cardiologists are most likely to be hospitalists? -What is the difference between invasive and interventional cardiology (or are they simply synonyms)? -How long are the fellowships for the following positions(I am assuming this is after you do a residency in internal medicine) Non invasive cardiology(is this just the cardiology you take after an im residency) Invasive cardiology(is this after cardiology fellowship?) Interventional cardiology (assuming if these two are different) Heart transplant -Isn't heart transplant a sub specialty of general surgery or of cardiology? -Also are there residencies out there that let you combine internal medicine and cardiology for a shorter residency? Can anybody clarify the different residencies with cardiology?
