Objective To investigate the significance of the changes in heart rate variability (HRV) in patients undergoing coronary artery bypass graft procedure Methods Thirty six patients scheduled for elective coronary artery bypass were studied HRV was monitored by HXD I monitoring system one day prior to surgery (as baseline values), before anesthesia, at the end of surgery and on the 3rd day and 6th day after surgery Results The baseline logical values for total power(TP), low frequency (LF), high frequency (HF), LF/HF ratio were 3 07?0 35, 2 38?0 47, 2 37?0 54 and 1 34?0 93 respectively There were no significant changes in all these parameters before anesthesia as compared to baseline values LF,HF and TP decreased significantly on the 3rd day after surgery as compared with baseline values, and were kept at the level on the 6th postoperative day Conclusions The decrease in HRV power can last over 6 days after coronary bypass graft surgery, signifying reduced autonomous regulation of heart in the early postoperative days

Objective:
To identify the incidence of hypertension, overweight/obesity in middle-aged population in China, and explore their impact on cardiovascular events.
Methods:
From 2009 to 2010, 12 areas were sampled in China, and about 1 000 subjects aged 35 - 64 from each area were enrolled to collect the basic information, physical examination and blood tests were also performed. From 2016 to 2017, data from 8 835 subjects, who completed the 6 years follow-up, were analyzed.Blood pressure and body mass index(BMI) at both baseline and the follow-up, as well as incidence of hypertension, overweight and obesity, were calculated. Cox proportional hazard model was used to investigate the impacts of hypertension, overweight and obesity on cardiovascular events after adjusting confounders.
Results:
At the end of follow-up, both BMI and systolic and diastolic blood pressure increased significantly compared with the baseline levels (all

Objective:
To evaluate the effects of standardized management of hypertension on blood pressure control of hypertension patients with diabetes mellitus in workplace population.
Methods:
Taking the type and size of workplace into consideration, 61 work sites were selected in different provinces by using epidemiological field trial method. In each selected province, 2-4 work sites with similar economic and medical conditions were chosen, among which 1-3 were designated as the intervention group and the other one as the control group. In total, 443 patients with hypertension and diabetes mellitus were included, with 347 patients in the intervention group and 96 patients in the control group. After training, doctors conducted standardized management for patients in the intervention group for a period of 24 months, following up with them regularly once a month, and recorded changes in blood pressure, risk factors, target organ damage, and treatment, while the control group had no special intervention, and relevant information was collected only at baseline and 24 months. Blood pressure, blood pressure control rate, and blood glucose changes were compared between the two groups.
Results:
After receiving standardized management of hypertension, the control rate of hypertension for patients with both hypertension and diabetes mellitus in the intervention group increased from 24.2% to 63.7% (
