| Objective To investigate the sleep quality of patients with acute myocardial infarction (AMI) after PCI and analyze the influencing factors. Methods Ninety-six patients with acute myocardial infarction underwent PCI during from Feb 2016 to June 2016 were selected. The PSQI of them was investigated by the Pittsburgh Sleep Quality Index (PSQI), and the influencing factors were analyzed. Results The sleep time scores of elderly patients (≥ 60 years) were significantly lower than those of young and middle-aged patients (<60 years); the sleep time, sleep quality, sleep disturbance, daytime function index and total sleep quality scores of elderly patients were significantly higher (P<0.05); sleep quality and sleep disturbance scores of female patients were higher than male patients (P<0.05); there were no significant differences in total sleep quality scores between female and male patients (P>0.05). Single factor analysis showed that age, exercise intensity, exercise time, postoperative medication, waist to hip ratio had significant effect on sleep quality, and multiple regression analysis showed that, waist to hip ratio(R2=0.482,P<0.01), exercise intensity(R2=0.415, P<0.01), exercise time (R2=0.337, P<0.01), postoperative medication(R2=0.327, P<0.01) were important factors influencing the sleep quality of the patients. Conclusion The quality of sleep in elderly patients with acute myocardial infarction is significantly lower than that in young and middle-aged patients; there was no significant difference in sleep quality between male and female patients, and waist to hip ratio, exercise intensity, exercise time, postoperative medication are closely related with sleep quality, so lifestyle intervention, reasonable exercise may probably improve sleep quality of patients with PCI. |
