The study objective was to describe the prevalence and correlates of sleep disturbances among women who retrospectively reported sleep disturbance before their myocardial infarction (MI). MI is frequently unrecognized in women because they may have only vague symptoms, such as sleep disturbance. Describing correlates of sleep disturbance before MI may assist in recognizing women at risk for coronary heart disease.
A secondary analysis was performed of a dataset derived from 15 sites.
Of 1270 women experiencing initial MI, 632 reported new onset of or worsening sleep disturbance before MI. Prevalence was similar across racial groups. Women reporting prodromal sleep disturbance were more likely to be older, to be heavier, and to report cognitive changes (adjusted odds ratio [OR], 1.47), new or increasing anxiety (adjusted OR, 2.21), and unusual fatigue (adjusted OR, 2.16).
Subjective reports of sleep disturbance preceding MI seem to be prevalent in women of all races and may be an important warning sign for MI in women.
本研究旨在描述在心肌梗死（MI）之前报告睡眠障碍的女性中睡眠障碍的患病率和相关因素。由于女性可能只有模糊的症状，如睡眠障碍，因此 MI 经常未被识别。描述 MI 前睡眠障碍的相关因素可能有助于识别患冠心病的高危女性。
对来自 15 个地点的数据进行了二次分析。
在经历初次 MI 的 1270 名女性中，有 632 名报告在 MI 前出现新发或加重的睡眠障碍。不同种族群体的患病率相似。报告前驱性睡眠障碍的女性更有可能年龄较大、体重较重，并报告认知改变（调整后的优势比 [OR]，1.47）、新出现或增加的焦虑（调整后的 OR，2.21）和异常疲劳（调整后的 OR，2.16）。
在所有种族的女性中，MI 之前出现的主观睡眠障碍报告似乎很常见，这可能是女性 MI 的一个重要预警信号。
