Determining the Benefits of Exercise on Cardiovascular Risk in PTSD
What this study is about
The purpose of this study is to use a non-invasive imaging technique called positron emission tomography/magnetic resonance imaging (PET/MRI) to investigate the effects of exercise on brain activity and arterial (blood vessel) inflammation in people with PTSD symptoms and evidence of or elevated risk for artery disease.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.

- Ability to understand and sign informed consent
Exclusion criteria
- History of stroke, brain surgery, or seizure
- Use of certain CVD medications (e.g., beta-blockers, high-intensity statins \[e.g., rosuvastatin 20/40 mg and atorvastatin 40/80 mg\], PCSK-9 inhibitors)
- Psychiatric or cardiovascular medication change within 4 weeks (i.e., stable regimen is allowed)
- Unstable blood pressure or cardiac arrhythmia
- Currently in a supervised or graduated exercise program
- Neurological or systemic inflammatory disease/current systemic anti-inflammatory therapy

- Current mania/psychosis
- Weight \>300 lbs.
- Claustrophobia
- Metal implants
- Uncontrolled hyperglycemia (HgbA1c\>7.5%)

Where
- Boston, Massachusetts
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
