title: [Blood pressure control and glucose metabolism status in hypertension specialty clinics in China].
abstract: OBJECTIVE
  To investigate blood pressure control the glucose metabolism, cardiovascular risk factors of patients who were regularly followed up at professional hypertension clinics in China.
  
  
  METHODS
  A cross-sectional survey was conducted in 32 004 patients from 127 professional hypertension clinics across China. The questionnaires included case history and related treatment physical examination and laboratory biochemical tests were also taken at the same time.
  
  
  RESULTS
  The mean blood pressure of overall population was (151 ± 13)/(92 ± 10) mm Hg(1 mm Hg = 0.133 kPa). Totally 3424 patients (10.7%) had never taken any anti-hypertension medicine. Among patients treated with anti-hypertension drugs, 19 818 were of mono-therapy (69.3%) and 8762 were of combination therapy. The most frequently used drug was renin-angiotensin system inhibitor, followed by calcium-channel blocker. Fixed compound preparations accounted for 15.6%. The overall blood pressure control rate (<140/90 mm Hg ) was 26.8%, among them, 27.7%, 30.0%, 25.4% and 21.3% patients were complicated with coronary heart disease, diabetes mellitus, kidney diseases and cerebral stroke respectively. About 70.3% hypertensive patients had abnormal glucose metabolism whose mean glycosylated hemoglobin (GHbA1c) was 7.84%, which was significantly higher than 7.0% , the target value defined by ADA.Even among them, 20.2% patients have never received any anti-diabetic drugs.Low-risk and medium-risk patients accounted for 16.0%. Totally 48.0% patients were classified in high-risk group and 36.0% in very high risk group. About half of all patients had different target organ dysfunction. About 49.0% patients had associated comorbidities.
  
  
  CONCLUSIONS
  Co-existence of hypertension and abnormal glucose metabolism is common in Chinese population. Among these patients, target organ dysfunction and comorbidities are prevalent, but blood pressure is only effectively controlled in less than 30% patients. Low proportion of combination therapy is one of the reasons for unsatisfied control of blood pressure.It indicates that effective management of hypertension is urgent.
