Why the study?
Does sympathetic stimulation improve regional function in pigs with hibernating myocardium compared to controls?
Does sympathetic stimulation improve regional function in pigs with hibernating myocardium compared to controls?
Functional responses to sympathetic stimulation are blunted in hibernating myocardium without catecholamine-induced hypersensitivity, suggesting a protective downregulation against demand-induced ischemia.
No takes yet. Share an insight, caveat, or question.
Blunted epinephrine responsiveness in hibernating myocardium suggests caution with sympathetic agents; leaves open adaptive downregulation mechanisms in chronic ischemia models.
Ovchinnikov et al. (2005) studied this question.
