The aim of this study is to determine whether the sleep-aid Eszopiclone can improve sleep, decrease inflammation, and decrease pro-coagulation factors in patients who have recently suffered myocardial infarction when compared with a control group without sleep aids. Eszopiclone is a benzodiazepine receptor agonist which improves sleep quality by reducing the time to sleep onset and reduces wakefulness during the sleep period. Unlike benzodiazepines, it does not affect the deeper stage 3 and 4 sleep. The result is that it provides a more nearly normal night sleep than other sleep aids. It is hoped that improved sleep patterns will result in more rapid normalization of inflammatory and coagulation factors and perhaps more rapid recovery.
