Final answer:
An angiogram is an imaging procedure using radioactive dye to visualize arteries, often identifying blockages, while angioplasty is a treatment method where a balloon catheter is used to open narrowed or blocked vessels to improve blood flow, frequently employing a stent to keep the artery open.
Step-by-step explanation:
An angiogram is a medical imaging technique used to visualize blood vessels, particularly arteries, to detect abnormalities such as blockages. A radioactive dye is injected into the arteries, which then becomes visible on an X-ray, revealing areas of occlusion (blockage). Angioplasty is a procedure designed to treat these blockages: a catheter with a balloon is fed into the artery to the occlusion site, then inflated to press the plaque against the artery wall and widen the vessel. This helps restore adequate blood flow and oxygen delivery to the affected tissues, preventing severe consequences like myocardial infarction (heart attack). In many cases, a mesh tube called a stent is also inserted to maintain vessel patency. Additionally, treatments such as lifestyle changes, medication or even surgery like endarterectomy or coronary bypass can be used to manage cardiovascular diseases.
When addressing how to "fix" arteries, angioplasty is an essential technique accompanied by the placement of stents, lifestyle modifications, and medication. The prevention or treatment of atherosclerotic disease is critical in maintaining cardiovascular health and preventing serious events such as heart attacks.
For those with blockages in their arteries, these interventions can significantly improve blood flow and quality of life, while also reducing the risk of future cardiac events. The concepts of angiogram and angioplasty, along with related treatments, are fundamental to the field of cardiology and vascular medicine and form a significant part of patient care in these domains.
