Heart Surgery / Cardiology
Cardiology is the specialty that deals with the diseases or disorders connected with the heart. It is the study of the heart and its functions whether in health or disease. A physician who treats heart ailments medically is known as cardiologist, and the cardiologist that specializes in surgery of the heart is known as cardiac surgeon (Heart Specialist).
Cardiologist is a specialist in diagnosis and treatment of congenital heart diseases, valvular heart disease, electrophysiology, coronary artery disease and heart failure. The main function of the heart is to pump blood and circulate it throughout the body.
Blood circulation in heart is of two types: systemic circulation and pulmonary circulation. When the blood is pumped from the body, it is known as systemic circulation, and when it pumps blood through the lungs, it is known as pulmonary circulation.
Heart diseases can affect the heart’s muscles, valves, heart’s electrical system, and the coronary arteries that feed the heart muscles.
Following are the common heart diseases:
Coronary Artery Disease (CAD): This is a very common, but a deadly form of heart disease. This is the disease of the blood vessel that supplies blood and nutrients to the heart.
Heart valve disease: This means that the valves that regulate blood flow in the heart are not functioning properly.
