The term really means the repairing of a coronary artery. In reality, there is complete tearing of the entire arterial wall (hence deserving the term angiolysis). The grossly damaged artery is further insulted by putting in of a foreign body called stent. The stent irritates the artery. The artery reacts by giving rise to thrombosis (blockage by blood clot) and tumor (endothelioma) around the stent, especially at the ends of the stent that dig into the arterial wall. The so called medicated stents carry a drug that suppresses the natural reparative response of the artery

You can not do good by doing evil. Neither angioplasty nor bypass mollycoddles the coronary vessels. Plasty is a gross tearing of all the arterial coats. Can an attempt be made to reread the nature of blood vessels and their relationship to the needs of the tissues they supply? The next section on TRAS Principles makes an attempt. Tissue Requisitions (Principle I) / Relinquishes (Principle II) Arterial Supply of TRAS principles is introduced to help appreciate the failure / successes of modern medicine's attempts at restoring arterial flow in luminally compromised coronary / carotid fields, an invasive branch rightly called vascular Re-rheology, which comprises diagnosing / treating arterial blocks. Like bypass Angioplasty with or without stent damages the heart often killing the complaining segment of the heart.  The dead part of the heart can no longer complain.  So you feel nice.

The Concise Oxford Textbook of Medicine 2000 describes angioplasty as 'inflation of a balloon to compress an atheromatous lesion, creating one or more tears within the plaque or the normal vessel wall opposite'. Coronary tear/s as part of coronary care!
