An Evolutionary Appraisal of the Efficacy of Coronary Artery Stents relevant to the Treatment of Coronary Heart Diseases

Abstract

Cardiovascular heart disease is one of the leading healthcare problems in this present era and need much care to prevent from this problem. The main reason for this problem is the accumulation of fats or plaque that blocks coronary arteries of heart which in turn resist the flow of blood to the heart walls and cause serious complications. The advancement in biomedical engineering and fabrication technology along with implantation technique made it possible and convenient to minimize the problems of coronary heart diseases. Small medical implantable device such as coronary stent which is a mesh like tube structure is one such emerging and stunning application which could be implanted in coronary artery with desirable yield and controllability. In this paper we have reviewed about causes of heart arteries blockage due to atherosclerosis and stenosis, about coronary stents implantation technique and different types of coronary stents available in present scenario.
