In this review article many research and review article on coronary stent has been reviewed thoroughly and prepared a review on the same basis. Percutaneous Coronary Interventions refers to both non-stenting procedures and stent interventions. Various types of stents are available in both Bare Metal Stent (BMS) as well as Drug Eluting Stent (DES). Various safety and efficacy studies have been performed to compare BMS and DES with variety of variables. Many studies favor BMS as a good option at low cost. However in the support of DES, many studies results show it's not inferior in term of safety than BMS. Even there are data available for comparative studies between BMS and DES for effectiveness by assessing Major Adverse Cardiac Event (MACE). Studies prove non inferiority of DES compared to BMS. Cost of DES is higher than BMS, in general, but Pharmacoeconomical Studies indicate that DES has greater ratio of effectiveness than cost.
