Cardiology (from Greek καρδίᾱ kardiā, "heart" and -λογία -logia, "study") is a branch of medicine that deals with the disorders of the heart as well as some parts of the circulatory system. A cardiologist is a physician who specialises in treating heart conditions such as abnormal heart rhythms, heart attacks, coronary artery disease, congenital heart defects, and disease of the heart valves.
A cardiologist can inform your doctor about new drugs or tests that may be beneficial to you.
Some heart conditions can cause permanent damage to the heart muscle, and can be fatal. Methods that cardiologists use to study heart conditions include stress tests, a monitor to record your heart rate and rhythm, a biopsy, which studies a tiny piece of heart tissue, and an echocardiogram, which uses sound waves to show a picture of how your heart works.
Interventional Cardiology
A wide range of coronary and peripheral interventional procedures are highly effective in diagnosing, preventing and treating heart disease. They include routine and emergency balloon angioplasty and coronary stenting.
