One-year clinical outcomes of different coronary drug eluting stents—Data from a prospective registry

We compared one-year clinical outcomes of different drug eluting stents (DES) used in a prospective observation registry maintained in two hospitals over three years. The primary endpoint was combination of all-cause mortality, stent thrombosis and revascularization. There was no significant difference among different DES. We grouped DES into well-evaluated Imported DES (Imported group), which used to be expensive prior to price control and economical Indian DES (Indigenous group) that lack supportive clinical trials. One-year follow-up data was available in 99% of Indigenous group (n=1856) and 98.5% of Imported group (n=1539). After propensity score matching, there were 1310 matched pairs. There was no significant difference between two groups in the primary end-point or each of the components.
