Key result
Contrast media triggers acute adverse reactions within 1 hour via complement and fibrinolytic activation.
Why the study?
Acute adverse drug reactions secondary to contrast media after cardiac catheterization occur within 1 hour and involve complex biochemical pathways, but risk identification remains unclear.
Can we identify patients at risk for acute adverse drug reactions with contrast media after cardiac catheterization?

Timing-based classification of contrast ADRs informs monitoring; Level 5 evidence leaves open targeted prevention.
Adverse reactions to contrast media are classified as acute or delayed reactions. Acute adverse drug reactions (ADRs) secondary to contrast media typically occur within 1 hour of contrast administration, as compared to within 1–7 hours for delayed reactions. ADRs have been attributed to the activation of complement and fibrinolytic systems along with the release of histamine, prostaglandins, leukotrienes, and bradykinins (1,2).

Mahtta et al. (2019) conducted a review in Acute adverse drug reactions to contrast media. Contrast media was evaluated. Contrast media administration can cause acute adverse drug reactions within 1 hour due to the activation of complement and fibrinolytic systems.
