The lack of obstructive coronary artery disease on coronary CT angiography safely reduces downstream cost and resource utilization during subsequent chest pain presentations

摘要: Abstract Objective The purpose of this study is to investigate the cost and resource use due chest pain (CP) evaluations after initial coronary CT angiography (CCTA) stratified by artery disease (CAD) burden. Methods We examined 1518 patients referred for CCTA from January 2005 July 2012 downstream evaluation during a median follow-up 351 days. Results were CAD burden as quantified on into no CAD, nonobstructive ( 90 days abstracted using ICD-9 codes Social Security Death Index query. A total 174 (11.5%) underwent CP index with higher rate subsequent clinical visits among obstructive compared those (17.8% vs 13.9% 7.5%; P  = .002). This resulted in lower per-patient (median [interquartile range 25–75 ]: $2952 [$307–2952] $235 [$0–2880]) when $5832 [$5498–17,459]; Conclusion Absence was associated costs decreased utilization presence
