title: Predictors of poor blood pressure control assessed by 24 hour monitoring in patients with type B acute aortic dissection.
abstract: The chronic management of post-acute aortic dissection (AD) of the descending aorta (Type B) is based on optimal control of blood pressure (BP), with a target BP < 135/80 mmHg. The aim of our study was to determine and verify effective blood pressure control with an objective measurement method and to identify predicting factors.
  
  
  METHODS
  We collected data from 26 patients hospitalized in the acute phase of a Type B AD between 2006 and 2009. Two groups were defined according to 24 hour BP monitoring results at follow-up. Group 1 consisted of patients with a controlled BP (<130/80 mmHg), and Group 2 consisted of patients with an uncontrolled BP.
  
  
  RESULTS
  Thirty four percent of patients showed an uncontrolled BP at checkup. Vascular history before AD (P = 0.06), high baseline BP trend (P = 0.01 for systolic and P = 0.08 for diastolic), and greater diameter of the descending aorta (P = 0.02) were associated with poor BP control.
  
  
  CONCLUSIONS
  Prognosis after AD is associated with BP control. Therefore, 24 hour BP monitoring can be made.
