Supervised Aerobic Exercise
Patients will exercise three times per week, under medical supervision, at a level of 70-85% of their VO2peak as determined at the time of their baseline exercise stress test. Patients' exercise will consist of 10 minutes of gradual warm-up exercises followed by 35 minutes of continuous walking, biking, or jogging, and 5 minutes of cool down exercises for a total a 50 minutes per session. Patients will be instructed to monitor their radial pulses and will be checked at least three times per session to ensure that they are within their prescribed exercise training ranges.

Lexapro
Treatment in the medication will be supervised by a study psychiatrist. Drug dispensing will be done by licensed pharmacists at the Duke Investigational Pharmacy Service. The investigators will use the SSRI escitalopram (Lexapro), which has received FDA approval for the treatment of anxiety, in 5 mg capsules. Medication will be dispensed as capsules of escitalopram in individually coded bottles. Medication adherence will be assessed using pill count at each study visit. Patients will visit face-to-face with a study psychiatrist at week 0 (baseline), week 1, week 2, week 4, week 8, and week 12 with phone encounters at weeks 3 and 6. The psychiatrist will make all medication adjustments based primarily upon Spielberger Anxiety Scores. Depending on symptoms, daily escitalopram doses will be titrated to 10 mg after week 2 and to 15 mg or placebo equivalent at week 3 if patients show no change or only minimal improvement.

Placebo
Treatment in the medication and placebo pill arms will be supervised by a study psychiatrist. Drug dispensing will be done by licensed pharmacists at the Duke Investigational Pharmacy Service, who have extensive experience in clinical trials. Medication will be taken once daily in the morning but can be switched to once daily in the evening if deemed necessary. Placebo medication administration will follow the same protocol as outlined for Lexapro.

SECONDARY outcome
Timeframe: Baseline, 3 monthsTo quantify heart rate variability (HRV), an electrocardiogram was recorded for 24-hours using the 3-channel DigiTrak XT Holter recorder (Philips Healthcare, Andover, Massachusetts). Electrocardiographic data were downloaded and edited using the Philips Zymed Holter analysis software (2010 Plus/1810 series) and HRV was estimated from the standard deviation of the normal-to-normal R-R intervals (SDNN).

Timeframe: Baseline, 3 monthsTo assess baroreflex sensitivity (BRS), beat-by-beat systolic blood pressure (SBP) and heart rate (HR) were collected using the Nexfin noninvasive BP monitor (Bmeye, Amsterdam, Netherlands). BRS was estimated from the magnitude of the transfer function relating R-R interval oscillations to SBP oscillations across the 0.07 to 0.1299 Hz, or low frequency band.

SECONDARY outcome
Timeframe: Baseline, 3 monthsEndothelial function, assessed by Flow-Mediated Dilation (FMD), was determined from longitudinal B-mode ultrasound images of the brachial artery. Images were obtained using an Acuson (Mountain View, California) Aspen ultrasound platform with an 11-MHz linear-array transducer after 10 min of supine relaxation and during reactive hyperemia, induced by the inflation of a forearm pneumatic occlusion cuff to suprasystolic pressure (about 200 mm Hg) and subsequent deflation after 5 min. FMD was defined as the maximum percentage change in arterial diameter relative to resting baseline from 10 to 120 s after deflation of the occlusion cuff.

Timeframe: Baseline, 3 monthsUrinary catecholamines, an index of sympathetic nervous system (SNS) activity, served as a biomarker of anxiety. Urinary concentrations of epinephrine (EPI) and norepinephrine (NE) were determined by high-pressure liquid chromatography (HPLC) with electrochemical detection (LabCorp). A composite 24-hr catecholamines z-score is presented. The z-score is the raw score minus the population mean, divided by the population standard deviation. A Z-score of 0 is equal to the mean. Negative numbers indicate values lower than the mean and positive numbers indicate values higher than the mean.
