Fetal echocardiography has shown that EFE can begin to accumulate as early as 14 weeks of gestation, and increase with incredible rapidity and even that it can be reversed if the stress can be removed early in fetal life.The North American Pediatric Cardiomyopathy Registry was founded in 2000 and has been supported since by the National Heart, Lung and Blood Institute. Because of the logic of the diagnostic tree, where EFE applies to many branches of the tree and thus cannot occupy a branch, it is not listed by the Registry as a cause but rather, "with EFE" is a modifier that can be applied to any cause.Thus, the past half-century has seen EFE evolve from a mysterious but frequently observed disease to a rare but much better understood reaction to many diseases and other stresses.

While all antidepressants help regulate sleep, some antidepressants, such as amitriptyline, doxepin, mirtazapine, trazodone, and trimipramine, can have an immediate sedative effect, and are prescribed to treat insomnia. Amitriptyline, doxepin, and trimipramine all have antihistaminergic, anticholinergic, antiadrenergic, and antiserotonergic properties, which contribute to both their therapeutic effects and side effect profiles, while mirtazapines actions are primarily antihistaminergic and antiserotonergic and trazodones effects are primarily antiadrenergic and antiserotonergic. Mirtazapine is known to decrease sleep latency (i.e., the time it takes to fall asleep), promoting sleep efficiency and increasing the total amount of sleeping time in people with both depression and insomnia.Agomelatine, a melatonergic antidepressant with claimed sleep-improving qualities that does not cause daytime drowsiness, is approved for the treatment of depression though not sleep conditions in the European Union and Australia. After trials in the United States, its development for use there was discontinued in October 2011 by Novartis, who had bought the rights to market it there from the European pharmaceutical company Servier.A 2018 Cochrane review found the safety of taking antidepressants for insomnia to be uncertain with no evidence supporting long term use. Melatonin agonists
Melatonin receptor agonists such as melatonin and ramelteon are used in the treatment of insomnia. The evidence for melatonin in treating insomnia is generally poor. There is low-quality evidence that it may speed the onset of sleep by 6 minutes.
