Objective: Based on stress theory, this paper proposes a fresh explanation of Radial Artery Spasm (RAS), the nature of which remains unclear.(1)Data Sources: Published research papers accessed via PubMedStudy Selection: Abstract review Data Extraction: Computerized Internet SearchData Synthesis: Fresh information relevant to stress theory derived from unrelated research enabled the description of a testable “mammalian stress mechanism” (MSM) that explains the stress theory proposed by Hans Selye. Conclusions: MSM activity explains the nature of RAS.
