Why the study?
Does a non-pressor dose of l-noradrenaline improve myocardial metabolism and function during ischaemia?
Does a non-pressor dose of l-noradrenaline improve myocardial metabolism and function during ischaemia?
A non-pressor dose of l-noradrenaline reverses myocardial K+ loss and improves contractility and arrhythmias during myocardial ischaemia in a preclinical model.

Hypothesis-generating for low-dose noradrenaline in ischaemia; requires clinical trials before any practice consideration.
Ventricular arrhythmias and diminished contractility during myocardial ischaemia have responded therapeutically to a non-pressor dose of l-noradrenaline. The free fatty acid oxygen extraction ratio was increased by ischaemia with a decline in glucose and pyruvate uptake, unaltered by noradrenaline. Myocardial K+ loss from ischaemic muscle was reversed by the hormone without affecting lactate production.
