Analgosedation raises baroreflex sensitivity in acute myocardial ischaemia.
Acute local myocardial ischaemia is associated with a decrease in baroreflex sensitivity while electrical instability (vulnerability) of ventricles increases. Co-administration of a benzodiazepine and a potent analgesic (analgosedation) has been found to raise both baroreflex sensitivity and ventricular fibrillation threshold. Pharmacological modulation of neurovegetative ionization of the heart in the early phase of ischaemia is a promising method for preventing sudden coronary death.
