Across China, there are an estimated 270 million people at present suffering from hypertension. We aimed to investigate the incidence of cardiovascular risk factors/clinical conditions, blood pressure (BP) control status among Chinese cardiac outpatients.Design and Method:
This multicenter cross-sectional survey was carried out from July 2014 to January 2015. The subjects were consecutively recruited from 119 hospitals in China. The subjects’ data was inputted into the database with touch screen integrated machines. The incidence of cardiovascular risk factors/clinical conditions, blood pressure control status was calculated.Results:
173598 outpatients’ data meeting inclusion criteria was involved in the statistical analysis. There were 111501 hypertensive (64.2%, mean age 59 ± 12 years old) and 62097 non-hypertensive (35.8%, mean age 48 ± 14 years old) patients. In hypertensive outpatients, overweight/obesity was found in 64.5%, physical inactivity in 46.5%, diabetes in 26.4%, dyslipidemia/high cholesterol in 33.1%, atrial fibrillation in 15.4%, stroke or transient ischemic attack in 12.0%. And the BP control (< 140/90 mmHg) rate was 31.0% in hypertensive patients, while 45.8%, 16.9% and 6.4% of patients were in patients with Grade 1, 2, and 3 hypertension, respectively. Meanwhile, in hypertensive patients there were 51.3% (57162/111501) without diabetes or dyslipidemia, 15.6% (17428/111501) with diabetes, 22.4% (24933/111501) with dyslipidemia, and 10.7% (11978/111501) with both. The proportion of hypertensive patients who complicated with diabetes, dyslipidemia or both had a positive relationship with age (F = 1007.899, P < 0.001) or obesity (BMI or abnormal waist) (χ2 = 2080.144, P < 0.001). And it had significant difference between different regions (χ2 = 1514.972, P < 0.001).Conclusions:
The incidence of cardiovascular risk factors/clinical conditions was high while the BP control rate was low among Chinese cardiac outpatients.
