Abstract:
Objective:To explore the correlation between sleep and the severity of coronary artery stenosis, and to further guide the prevention and control of coronary heart disease.
Methods:A total of 302 patients, including 183 males and 119 females, were enrolled in the department of cardiology of Changhai hospital from February to June 2019. The patients were divided into three groups according to the degree of stenosis (atherosclerotic group, atherosclerotic group with degree of stenosis <50%, atherosclerotic group with degree of stenosis 50%-70%, and atherosclerotic group with degree of stenosis >70%). General information, comorbidities and Pittsburgh sleep quality index (PSQI) of patients in each group were analyzed to compare the differences and analyze the risk factors of aggravated coronary artery stenosis.
Results:There were statistically significant differences in age, gender and diabetes among all groups (P<0.05). There was no statistically significant difference in the incidence of hypertension and hyperlipidemia in each group (P>0.05). Spearman correlation analysis showed that PSQI score was positively correlated with the degree of atherosclerosis (P<0.01). In the multivariate regression model, poorer sleep quality (OR=1.75, 95% CI: 1.14-2.69, P<0.05), shorter sleep time (OR=1.64, 95% CI: 1.05-2.55, P<0.05) and more diurnal dysfunction (OR=1.45, 95% CI: 1.11-1.88, P<0.01) were correlated with increased coronary artery stenosis. Higher PSQI total score (OR=1.13, 95% CI: 1.06-1.20, P<0.01) and lower PSQI evaluation grade (very bad vs very good: 13.85, 95% CI: 1.56-122.82, P<0.05) were also related to the increase of coronary artery stenosis.
Conclusions:Poorer sleep quality, shorter sleep time and more diurnal dysfunction were independent risk factors for the aggravation of coronary artery stenosis. Higher Pittsburgh sleep quality index was significantly associated with the severity of coronary artery stenosis.
