Primary Outcome Measures:
  • 1.To Investigate the Effects of Escitalopram on Cardiac Vagal Function as Measured by R-R Interval Variability, Especially in the HF (0.15-0.5 Hz) Band in OEF/OIF Veterans With PTSD. [ Time Frame: 12 Weeks ] [ Designated as safety issue: No ]
  • To Investigate the Effects of Escitalopram on an Absolute or Relative Decrease in Cardiac Sympathetic Function and Serious Cardiac Side Effects as Measured by QT Interval Variability in OEF/OIF Veterans With PTSD. [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]

Enrollment: 11
Study Start Date: June 2008
Study Completion Date: June 2013
Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: PTSD Depression Group
Escitalopram 10-20 mg/day
Drug: Escitalopram
10-20mg daily for 12 weeks
Other Name: Lexapro
Active Comparator: Major Depression Group
Escitalopram 10-20 mg/day
Drug: Escitalopram
10-20mg daily for 12 weeks
Other Name: Lexapro

Detailed Description:

The investigators are studying if taking escitalopram will normalize heart rate variability and a decrease (or no effect implying a lack of serious cardiac side effects) including QT variability in veterans with PTSD.

Criteria

Inclusion Criteria:

  • Inclusion Criteria - Group I
  • Patients, men and women between 19 and 55 years of age, inclusive.
  • Patients with diagnosis of Posttraumatic Stress Disorder as determined by Mini-International Neuropsychiatric Interview (M.I.N.I.).
  • Patients, who are able to comprehend and satisfactorily comply with protocol requirements and have an ability to read and write English.
  • Patients, who signed the written informed consent given prior to entering any study procedure.
  • Inclusion Criteria - Group II
  • Patients, men and women between 19 and 55 years of age, inclusive.

-Patients with diagnosis of Major Depression as determined by Mini- International Neuropsychiatric Interview (M.I.N.I.). A diagnosis of PTSD will be exclusionary.

  • Patients, who are able to comprehend and satisfactorily comply with protocol requirements and have an ability to read and write English.
  • Patients, who signed the written informed consent given prior to entering any study procedure.

Exclusion Criteria:

  • History of cardiovascular disease or a history of hypertension.
  • Patients with a concurrent DSM-IV diagnosis in any of the following categories as determined by the M.I.N.I.
  • Lifetime Schizophrenia and Schizoaffective Disorder
  • Lifetime Bipolar I Disorder
  • Substance Dependence or Abuse (excluding nicotine) within one month prior to the Screening Visit.
  • Patients with a history of intolerance or hypersensitivity to escitalopram or citalopram.
  • Patients who based on history or mental status examination have a significant risk of committing suicide. Current suicide risk (past month) will be assessed using the MINI Suicidality Module. Subjects considered at high suicide risk based on the module (> 17 points) will be excluded from study participation.
  • Patients who are homicidal or violent and who are in the Investigator's opinion in significant imminent risk of hurting others.
  • Subjects will be excluded who have a history of significant medical illness and who are on medications that affect cardiac and/or autonomic function.
  • Female patients who are pregnant, planning to become pregnant, or if of childbearing potential, not using an acceptable method of birth control.
