PURPOSE: It is generally believed that deployment of multiple stents during percutaneous coronary intervention (PCI) is associated with higher incidence of complications. The objective of the study was to determine the incidence of major adverse cardiac outcomes (MACE) associated with multiple stent deployment and its comparison with the deployment of single stent.
METHODS: Study cohort was formed by all patients who had percutaneous intervention done during January 2003 to August 2004 at our institution. A retrospective review of their medical records was done to obtain data regarding cardiac risk factors, medications at discharge and MACE [cumulative of death, myocardial infarction(MI) and target vessel revascularization (TVR)].
RESULTS: A total of 333 patients underwent PCI who were followed up for a mean duration of 36 ± 5 months. 208 patients (62%) received a single stent whereas the remaining 38% received two or more stents. Cardiac risk factors and medications at discharge were similar in patients with single or multiple stent deployment. 21 patients (10%) in single stent group and 7 patients (6%) in multiple stent group had MI (p value=0.15). Both groups had similar TVR and MACE over the follow up period of 3 years(Table 1).
CONCLUSION: There is no significant association between the number of stents deployed during PCI and the incidence of long term adverse cardiac outcomes.
CLINICAL IMPLICATIONS: This study provides long term outcome data on multiple stent deployment during percutaneous coronary interventions.
