The ten advances that have defined modern cardiology.

Modern cardiology was born early in the twentieth century. Here I list and review what I believe to be the ten most important advances in the twentieth century in this field. They are as follows: electrocardiography, cholesterol-induced atherosclerosis, cardiac catheterization, cardiovascular surgery, coronary angiography and percutaneous coronary angioplasty, the coronary care unit, the development of new cardiovascular drugs, preventive cardiology, cardiac imaging, and implanted cardiac pacemakers/defibrillators.
