title: [Current status of morning blood pressure control and medication of hypertensive patients in Beijing].
abstract: OBJECTIVE
  To explore the current status of morning blood pressure and medication of hypertensive patients in Beijing.
  
  
  METHODS
  This study included 2187 hypertensive patients who visited the ambulance of our cardiology department in the morning (7:00-10:00) from March 2012 to April 2012. Patients were divided into three groups: no antihypertensive agent group, single antihypertensive drug therapy group (include CCB, ARB, ACEI, β-blocker) and combined drug therapy group at least one month. Blood pressure control rate was compared among the groups.
  
  
  RESULTS
  Target blood pressure was not reached in 1193 patients (54.6%), most patients took CCB and the target blood pressure was not reached in 61.7% (295/478) patients taking CCB. There was no significant difference on target blood pressure uncontrolled rate among the four single drug subgroups (CCB, ARB, ACEI, β-blocker). The blood pressure uncontrolled rate was 46.3% (63/136) for amlodipine, 70.5% (55/78) for nifedipine and 73.8% (31/42) for felodipine. There OR of uncontrolled blood pressure rate was 0.36 (amlodipine vs. nifedipine, 95%CI:0.20-0.65) and 0.31% (amlodipine vs. felodipine, 95%CI:0.14-0.66).
  
  
  CONCLUSIONS
  The morning blood pressure uncontrolled rate is high in hypertensive patients visiting Beijing tertiary hospitals. Amlodipine is possible superior to nifedipine and felodipine on morning blood pressure control in this patient cohort.
