Hypothesis that beta-blockers may blunt contrast haemodynamics; leaves open prospective validation before any clinical use.
Do specific beta-adrenergic blocking agents counteract the immediate haemodynamic effects of intra-cardiac injection of contrast media?
The authors hypothesize that the immediate haemodynamic effects of angiocardiography contrast media are mediated by beta-adrenergic receptors and could be counteracted by beta-blockers.
Reale et al. (1967) studied this question.
