👉 Cardiologists are medical specialists who specialize in treating conditions of the heart and blood vessels, including coronary artery disease, heart failure, heart valves, and other cardiovascular diseases. They work closely with surgeons to diagnose and treat these conditions. Cardiologists also perform surgeries such as angioplasty (introducing a bypass to allow blood flow through blocked arteries) and stenting (the removal of plaque or blockages in the walls of arteries).
