This study was to examine the effects of sleep habits on acute myocardial infarction (AMI) risk and severity of coronary artery disease (CAD) in Chinese population from two centers. A total of 873 patients were recruited from the inpatient cardiology department of the Affiliated Jiangning Hospital and the First Affiliated Hospital of Nanjing Medical University. Investigators used a 17-item sleep factors questionnaire (SFQ) to evaluate sleep habits comprehensively by face-to-face interview.
Growing evidence indicates that poor sleep harms health. Early to bed and early to rise is considered as a healthy lifestyle in Chinese population. The current study aimed to examine the effects of sleep habits on acute myocardial infarction (AMI) risk and severity of coronary artery disease (CAD) in Chinese population from two centers. A total of 873 patients including 314 with AMI were recruited from the inpatient cardiology department of the Affiliated Jiangning Hospital and the First Affiliated Hospital of Nanjing Medical University. 559 controls included 395 CAD cases and 164 non-CAD cases. Investigators used a 17-item sleep factors questionnaire (SFQ) to evaluate sleep habits comprehensively by face-to-face interview. The severity of CAD was assessed by Gensini score in AMI and CAD groups. The effects of sleep factors on AMI risk and Gensini score were examined by unconditional logistic regression. The timing of sleep (24:00 and after), sleep duration (<6h) and frequency of night-time waking (3 times) increased the risk of AMI. In subjects with age ≤60 years, daytime napping reduced the risk of AMI. The correlation between sleep quality and AMI became insignificant after subgroup analysis by age. Short sleep duration also increased the risk of high Gensini score.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| control group | Patients hospitalized and diagnosed as non-AMI during the same time period were matched. All patients underwent coronary angiography and CAD was defined as at least one main coronary artery with > 50% narrowing of luminal diameter. | ||
| AMI group | Patients were diagnosed as MI when a cardiac biomarker (preferably cardiac troponin) rose or fell at least one value in its 99th percentile upper reference limit and at least one of the following criteria was met, including ischemic symptoms, electrocardiogram (ECG) changes of new ischemia, pathologic Q waves in the ECG, imaging evidence of new loss of viable myocardium or new regional wall motion abnormality, identification of an intracoronary thrombus by angiography or autopsy. |

A case-control study was designed to investigate the effects of sleep habits on AMI and severity of CAD. After patients were in stable condition, trained physicians administered a questionnaire survey by a face-to-face interview. Information on demographic characteristics, hypertension, diabetes and dyslipidemia history, drug use, smoking, drinking, dietary habits, exercise and sleep habits were collected.
