B-115 | Sex-Based Differences in PCI Outcomes: Lower Procedural Complications Despite Greater Comorbidities in Women

professionals, persist.As part of an upgrade, Lahey Clinic installed reduced-dose angiographic equipment to minimize radiation.This study evaluates the efficacy of this equipment compared to standarddose equipment.Methods: A retrospective analysis was conducted using invasive coronary procedures, including diagnostic coronary angiography and percutaneous coronary intervention (PCI) from May to July 2023.Invasive coronary procedures were divided into two groups: Group A (reduced-dose equipment, 99 cases) and Group B (standard-dose equipment, 94 cases).The primary outcome was Absorbed Energy Dose (AED, measured in milligrays (mGy)), while fluoroscopy time was the secondary outcome.Statistical analyses, including t-tests and regression models, were used to compare groups.Results: Group A demonstrated a 32.7% reduction in AED compared to Group B (864.62 AE 881.88 mGy vs. 943.51AE 733.61 mGy, P < 0.001), based on a log transformed analysis.Fluoroscopy time was longer in Group A (13.62 AE 16.33 minutes) than in Group B (9.35 AE 7.44 minutes, P 0.03).No significant demographic differences were observed, ensuring comparability between the groups.Conclusions: The implementation of reduced-dose angiographic equipment resulted in a significant reduction in radiation exposure, as demonstrated by lower AED, despite an increase in fluoroscopy time.These findings highlight the importance of adopting advanced imaging technology to enhance radiation safety along with other best practices including time, distance, and shielding to achieve a radiation dose as low as reasonably achievable (ALARA).
