There are 3 main kinds of cardiology: invasive, non-invasive and interventional. Interventional cardiology may be a non-surgical choice that uses a catheter – a little, versatile tube – to repair broken or weakened vessels, narrowed arteries, or different affected elements of the heart structure. Common conditions treated by interventional cardiology are arterial coronary sickness, Heart valve disease and Peripheral vascular sickness. Invasive cardiology uses open or minimally-invasive surgery to spot or treat structural or electrical abnormalities among the heart structure. Common kinds of invasive cardiology are angioplasty and Stenting. Non-invasive cardiology identifies heart issues without using any needles, fluids, or alternative instruments that are inserted into the body. Non-invasive cardiologists utilize techniques such as; nuclear cardiology, ECG, cardiac electrophysiology, Stress tests, Heart monitors and CT scans.
