These are two different things that are related to the health of the heart. An angiogram is known to be a type of test that will help test what arteries that are leading to the heart have already narrowed. This will be effective in checking out the web of arteries and veins and knowing which ones would need to be treated soon.
The angioplasty is the procedure or treatment that will be done to prevent the arteries from narrowing further. People who have heart conditions are required to do some lifestyle changes and also to undergo some treatments if necessary to help improve their heart health.
