[1] [2] Neointimal hyperplasia is the major cause of restenosis after percutaneous coronary interventions such as stenting or angioplasty. [1] The term neointima is used because the cells in the hyperplastic regions of the vascular wall have histological characteristics of both intima and normal artery cells.
Diagram of stent placement. In A, the catheter is inserted across the lesion. In B, the balloon is inflated, expanding the stent and compressing the plaque. In C, the catheter and deflated balloon have been removed. Before-and-after cross sections of the artery show the results of the stent placement. Arterial Stenting 3D Medical Animation
After placement of a stent or scaffold, the patient needs to take two antiplatelet medications (aspirin and one of a few other options) for several months to help prevent blood clots. The length of time a patient needs to be on dual antiplatelet therapy is individualized based risks of ischemic events and bleeding risk.
Percutaneous access and procedures frequently refer to catheter procedures such as percutaneous transluminal angioplasty (PTA) ballooning, stent delivery, filter delivery, cardiac ablation, and peripheral or neurovascular catheter procedures but also refers to a device that is implanted in the body, such as a heart pump (LVAD), and receives ...
A diet high in fruits and vegetables decreases the risk of cardiovascular disease and death. [97] Vegetarians have a lower risk of heart disease, [98] [99] possibly due to their greater consumption of fruits and vegetables. [100] Evidence also suggests that the Mediterranean diet [101] and a high fiber diet lower the risk. [102] [103]
Infarct area and arterial calcium can also be observed (however those require a somewhat higher radiation exposure). That said, one advantage retained by Catheter angiography is the ability of the physician to perform procedure such as balloon angioplasty or insertion of a stent to improve blood flow to the artery.

A percutaneous coronary intervention, or coronary angioplasty with stenting, is a non-surgical procedure used to improve the blood flow to the heart. [ 1 ] Coronary angioplasty is indicated for coronary artery diseases such as unstable angina , NSTEMI , STEMI and spontaneous coronary artery perforation. [ 1 ]
