An Overview on Coronary Artery Disease and Cardiovascular Stents

Coronary artery disease (CAD) is commonly called coronary heart disease, a condition with inadequate supply of blood and micronutrient to heart due to narrowing of arteries. Generally, symptoms are not seen in early stages but as disease progress common signs such as discomfort in chest, shortness of breath, tiredness and irregular heartbeats are detected. Primarily, CAD was one of the uncommon causes of death in the start of 20th century. But this scenario was changed from mid 1960s as peaks were observed in CAD deaths. At present, CAD is leading cause of death worldwide, though there is significant decline. However, there are treatments available for this medical condition such as angioplasty and stent placement. In this review, we present a detail study on diagnosis, risk factors, potential treatment options using different stents and their availability as well as relevant benefits. Furthermore, the future prospects of stent technology are also discussed.
