OBJECTIVES: The objectives of this work were to establish the primary clinical determinants of @entity1 radiation dose associated with percutaneous coronary interventional (PCI) and to identify opportunities for dose reduction. BACKGROUND: Use of X-ray imaging and associated radiation dose is a necessary part of PCI. Potential adverse consequences of radiation dose include @entity272 and predicted increase in lifetime @entity5 risk. METHODS: @entity272 ( @entity272 ) (measured in gray [Gy] units) was selected as a measurement of @entity1 radiation burden. Several @entity1 -, disease-, and treatment-related variables, including 15 performing physicians, were analyzed in a multiple linear regression statistical model with cumulative skin dose @entity272 as the primary end point. The model results provide an estimate of the relative @entity272 increase (decrease) attributable to each variable. RESULTS: Percutaneous coronary interventions performed on 1,287 male and 540 female @entity1 were included. Median @entity1 age was 68.6 years, median body mass index was 29.7 kg/m(2), and median weight was 88 kg. Median @entity272 was 1.64 Gy per procedure for male and 1.15 Gy for female @entity1 . Increasing body mass index, @entity1 sex, lesion complexity, lesion location, and performing physician were significantly associated with @entity272 . Physicians who performed more procedures were associated with lower @entity272 . CONCLUSIONS: Several primary determinants of @entity1 radiation dose during PCI were identified. Along with physician development of radiation-sparing methods and skills, pre-procedure dose planning is proposed to help minimize radiation dose for PCI.
