title: [A survey of factors influencing prognosis and control rate for patients with hypertension in mainland China].
abstract: OBJECTIVE
  To observe the risk factor stratification and prevalence of target organ damage in hypertensive patients before therapy and blood pressure control rate after 4 or 12 weeks antihypertensive drug therapy.
  
  
  METHODS
  In this prospective survey, data on cardiovascular risk factors, target organ damage and concomitant disease were collected in 26 655 hypertensive patients. Among them 26 325 and 3457 patients were recruited for antihypertensive drug therapy for 4 and 12 weeks, respectively and blood pressure control rate was determined.
  
  
  RESULTS
  The sedentary lifestyle, smoking, high body mass index, dyslipidemia were found in 52.5%, 34.4%, 31.8%, 24.5%, and microproteinuria, left ventricular hypertrophy, coronary artery disease and diabetes in 21.0%, 23.6%, 20.1%, 26.7% hypertensive patients, respectively. The average systolic and diastolic pressures were 158 +/- 14 mm Hg and 94 +/- 11 mm Hg and 3.2%, 22.2%, 21.1% and 53.3% patients were defined as low, medium, high and very high risk patients in risk stratification to quantify prognosis. There were 77.2%, 20.4% and 2.4% systolic and diastolic, isolated systolic and isolated diastolic hypertensive patients respectively. The goal blood pressure control rate was 50.2% and 56.7% respectively after 4 and 12 weeks antihypertensive drug therapy. The control rate in patients complicated with diabetes and renal disease was significantly lower than patients without them and systolic pressure control rate was remarkably lower than diastolic pressure control rate. Majority patients required 2 or more antihypertensive drugs for effective pressure control (1.5 drug per patients in average in both 4 or 12 weeks groups).
  
  
  CONCLUSIONS
  The prevalence of risk factors, target organ damage and concomitant disease were high in Chinese patients with hypertension and comprehensive interventions were indicated. To reach goal blood pressure control in patients with hypertension, follow up intensifying and drug therapy guidance are required within the context of usual medical care.
