Patients with coronary diseases admitted to special care unit often suffer from sleep disorders, which may cause physiological changes and adversely affect patient's health. The relationship between sleep disorders and obesity is an important factor in studies on sleep disorders and other chronic diseases in all groups, including cardiovascular diseases. Understanding this relationship may increase the chance of progress in effective medical interventions in sleep disorders and obesity. This study was designed to evaluate the association between short sleep and Body Mass Index (BMI), hypertension among acute coronary syndrome patients.
MATERIALS & METHODS: In this descriptive analytical study, 221 coronary patients admitted to coronary care unit and general wards were investigated. Data were collected through a researcher-made questionnaire whose validity and reliability had been confirmed. Data were analyzed with SPSS-16 software.
A total of 221 patients with acute coronary diseases (including myocardial infarction and angina pectoris) with a mean age of 61.27 years were studied, of whom 61.5% were male and 38.5% were female. A significant association was observed between short sleep and higher BMI (P=0.000). About half the patients (49.3%) had a history of hypertension, and sleep disorders were also significantly related to hypertension (P=0.006).
In this study, sleep disorders were patients' main complaint. Researchers found that patients with less than 5 hours or more than 9 hours sleep at night were more likely to have hypertension compared to patients that slept 7-8 hours. Lack of sleep affects metabolism, and daily energy expenditure reduces with increased immobility. In this study, a significant relationship was observed between BMI and sleep duration among hospitalized patients in coronary care unit (P=0.000), and sleep disorders increased with higher BMI. Short of sleep increases sympathetic tonus, cortisol level, and activation of inflammatory pathways, impairing glucose metabolism and contributing to overweigh, increased visceral fat.
Our findings suggest that poor sleep quality, is related to higher BMI and hypertension among acute coronary syndrome patients.
入住重症监护病房的冠心病患者常伴有睡眠障碍，这可能导致生理变化并对患者健康产生不利影响。睡眠障碍与肥胖之间的关系是包括心血管疾病在内的所有群体睡眠障碍及其他慢性病研究中的一个重要因素。了解这种关系可能会增加在睡眠障碍和肥胖的有效医学干预方面取得进展的机会。本研究旨在评估急性冠脉综合征患者短睡眠与体重指数（BMI）、高血压之间的关联。
在这项描述性分析研究中，对入住冠心病监护病房和普通病房的221例冠心病患者进行了调查。通过一份经证实有效性和可靠性的研究者自制问卷收集数据。使用SPSS - 16软件进行数据分析。
共研究了221例急性冠心病患者（包括心肌梗死和心绞痛），平均年龄61.27岁，其中男性占61.5%，女性占38.5%。观察到短睡眠与较高的BMI之间存在显著关联（P = 0.000）。约一半患者（49.3%）有高血压病史，睡眠障碍也与高血压显著相关（P = 0.006）。
在本研究中，睡眠障碍是患者的主要诉求。研究人员发现，与睡眠7 - 8小时的患者相比，夜间睡眠少于5小时或多于9小时的患者患高血压的可能性更大。睡眠不足会影响新陈代谢，随着活动减少，每日能量消耗也会降低。在本研究中，冠心病监护病房住院患者的BMI与睡眠时间之间存在显著关系（P = 0.000），且睡眠障碍随BMI升高而增加。睡眠不足会增加交感神经张力、皮质醇水平并激活炎症途径，损害葡萄糖代谢，导致体重超重、内脏脂肪增加。
我们的研究结果表明，睡眠质量差与急性冠脉综合征患者较高的BMI和高血压有关。
