We investigated the prevalence and characteristics of ischemic heart disease especially silent myocardial ischemia (SMI) and arrhythmia in need of careful observation in the exercise stress tests in the Total Health Promotion Plan (THP), which was conducted between 1994-96 for the purpose of measuring cardiopulmonary function. All workers (n = 4,918, 4,426 males) aged 18-60 yr old in an occupational field were studied. Exercise tests with an ergometer were performed by the LOPS protocol, in which the maximal workload was set up as a presumed 70-80% maximal oxygen intake, or STEP (original multistage protocol). ECG changes were evaluated with a CC5 lead. Two hundred and fifteen people refused the study because of a common cold, lumbago and so on. Of 4,703 subjects, 17 with abnormal rest ECG and 19 with probable anginal pain were excluded from the exercise tests. Of 4,667 who underwent the exercise test, 37 (0.79%) had ischemic ECG change, and 155 (3.32%) had striking arrhythmia. These 228 subjects then did a treadmill exercise test with Bruce protocol. Twenty-two (0.47% of 4,703) showed positive ECG change, 9 (0.19%) of 22 had abnormal findings on a 201Tl scan. 8 (0.17%) were diagnosed as SMI (Cohn I), in which the prevalence of hypertension, hyperlipidemia, diabetes mellitus, smoker and positive familial history of ischemic heart disease was greater than that of all subjects. In a 15-30 month follow up, none has developed cardiac accidents. Exercise-induced arrhythmia was detected in 11 (0.23%) subjects. Four were non-sustained ventricular tachycardia without any organic disease, 4 were ventricular arrhythmia based on cardiomyopathy detected by echocardiography, 2 were atrial fibrillation and another was WPW syndrome. It is therefore likely that the ergometer exercise test in THP was effective in preventing sudden death caused by ischemic heart disease or striking arrhythmia.

This study was designed to survey the prevalence and risk factors of hypertension in Uygur adults in Tushala Township, Hetian area of Xinjiang Uygur Autonomous Region. Cross-sectional study of possible risk factors for hypertension was conducted in Tushala and in 28 surrounding villages using a stratified random sampling method. A modified version of the WHO STEP wise approach for risk factor survey was employed. Data collection on these relevant risk factors was performed using the WHO STEPS approach. Physical and body parameters were collected and used for analysis of variance. In addition, risk factors for hypertension were screened using a multifactor logistic regression analysis. The prevalence of hypertension in Hetian Township was 25.6%. The incidence of hypertension was positively correlated with body mass index and triglyceride cholesterol. There was also a positive correlation between risk of hypertension and levels of waist-to-hip ratio as well as abdominal circumference (AC). Logistic regression analysis exhibited AC as the predominant risk factor while high-density lipoprotein as the main protective factor for hypertension. In conclusion, our results indicated that high caloric food intake may trigger hyperlipidemia and subsequently elevated blood pressure, with elevated BMI and cholesterol levels being the major risk factors for hypertension.
