What is a Cardiologist? A cardiologist is a medical doctor who specializes in treating problems of the heart, arteries, and veins, collectively known as the cardiovascular system. Conditions that may require the attention of a cardiologist include shortness of breath, chest pains (angina), and dizzy spells. Cardiologists also treat patients with heart disease, heart murmurs (arrhythmia), and victims of heart attacks or heart failure. They typically make decisions about when to perform heart-related procedures such as angioplasty, heart surgery, and heart transplants.
