Final answer:
A physician and a surgeon are two types of practitioners who can hold a Doctor of Medicine degree. Cardiologists are specialized physicians who require extensive training and certification, with outstanding individuals potentially earning the distinction of FACC.
Step-by-step explanation:
Two types of practitioners who can hold the degree of Doctor of Medicine are a Physician and a Surgeon. After completing medical school, a cardiologist, who is a specialized type of physician, will undergo extensive post-graduate training including a three-year residency in internal medicine and additional years focusing on cardiology. Upon completion of this rigorous training, they must then pass a two-day examination to become a board-certified cardiologist. Exceptional board-certified cardiologists can achieve further recognition by becoming a Fellow of the American College of Cardiology (FACC).
