| Objective: Many studies have shown that sleep disorders are associated with increased risk of coronary heart disease.In this study,we investigated the correlation between heart rate variability(HRV)indicators,pittsburgh sleep quality index(PSQI)components and coronary heart disease in patients with sleep disorders,so as to explore the predictive indicators of coronary heart disease in patients with sleep disorders.Methods: A total of 46 patients with sleep disorders hospitalized from January 2016 to October 2019 were included,divided into 21 patients with coronary heart disease and 25 patients with non-coronary heart disease,collect the patient’s general data and biochemical indicators,prevalence,Pittsburgh sleep scale,HRV indicators,etc.,analyze the relationship between PSQI and HRV indicators of each group and coronary heart disease.Results:1.There were differences in sleep quality,sleep time,sleep efficiency,total score,LF / HF and low-density lipoprotein(P <0.05),and the total score,LF / HF and low-density lipoprotein indicators in the coronary heart disease group were higher than those in the non-coronary heart disease group,and the remaining indicators were not different between the two groups.2.Sleep quality,sleep time,sleep efficiency,total score and LF / HF indicators are related to the occurrence of coronary heart disease.3.Sleep quality,sleep efficiency and low-density lipoprotein,LF / HF and low-density lipoprotein construct Logistic model to predict the occurrence of coronary heart disease in patients with sleep disorders,the predicted percentages are 63% and 71.7%,respectively.4.The joint indicators of sleep quality,sleep efficiency and low-density lipoprotein,the combined indicators of LF / HF and low-density lipoprotein,and the LF / HF drawing of ROC curves for the diagnosis of coronary heart disease have statistical significance.5.Sleep quality,sleep time,sleep efficiency,and total score are related to LF / HF,and with the increase of the level and score of the four indicators,the LF / HF indicator is an upward trend.Conclusions: This study found that sleep quality,sleep efficiency combined with low-density lipoprotein,or LF / HF combined with low-density lipoprotein can predict the occurrence of coronary heart disease in patients with sleep disorders,and has certain clinical value.Can be combined with other indicators to determine the incidence of coronary heart disease in patients with sleep disorders. |
