Cardiology is the branch of science that examines diseases related to the heart and circulatory system. Cardiology, which was a sub-branch of the internal medicine department, is now a separate department. A doctor with medical education gets the title of cardiologist by making his specialty in cardiology. People who have symptoms such as fatigue, cyanosis, palpitations, fainting, night urination, edema, shortness of breath, chest pain are treated in the cardiology department. The heart's main task is to pump blood around the body. If the heart cannot pump enough blood that the body needs for various reasons, heart failure occurs. Cardiology Ideals with many diseases such as hear failure, hypertension, ischemic heart diseases, atherosclerotic coronary artery disease and acute coronary syndrome.
