Brief Summary
The goal of this study is to assess a slimy substance that settles/deposits along blood vessel wall. This slimy substance is called plaque. Plaque could be made up of fat, calcium or both. Plaque deposition narrows the vessels. This leads to decreased blood flow to various parts of body. Blood vessels include vessels that supply to heart (coronary), vessels to brain (carotid), vessels to kidneys (renal) and vessels to legs (femoral). Decreased blood flow causes symptoms such as brain stroke, heart attack, leg pain. Similarly individuals at risk of cardiovascular disease can have certain markers elevated in their blood that can be measured by simple blood tests. High or increased plaque deposition is seen in neck vessels of cancer patients who received radiation to chest or head and neck as part of their cancer treatment. Cancer survivors are at increased risk of plaque development and are therefore called high-risk population. Exercise +/- fat lowering medicine can potentially decrease plaque deposition and statins are one of the several fat lowering medications.

Outcome Measures
Primary Outcomes (1)
Plaque Volume of Carotid Arteries
Plaque volume of carotid arteries were measured by MRI as a surrogate for progression of cardiovascular disease. Plaque volume varies with observed ranges from other studies ranging from 23.9 to 604.1mm\^3. Plaque volume tends to increase with age. Increased plaque volume has an increased risk of vascular events.
Baseline, 18 months, 36 months
Study Arms (2)
Lifestyle modification
ACTIVE COMPARATORLifestyle modification is tailored to each participant and includes a recommended exercise regimen, a healthy diet and decreasing alcohol intake.
Statin therapy
EXPERIMENTALParticipants will receive statin medication along with instruction about regular exercise.
Interventions
Statin therapy includes rosuvastatin 20 mg administered orally, once a day, for the duration of the trial, which is 3 years. Participants may also receive a different type of statin as prescribed by their cardiologist based on clinical judgement.
Lifestyle modification includes a recommended exercise regimen, a healthy diet and decreasing alcohol intake for 3 years.
Eligibility Criteria
You may qualify if:
- Age 22 and above with prior head and neck or chest irradiation
- Six months or more post head and neck irradiation
- Documented subclinical cardiovascular disease (inflammatory markers in the serum)
- Pre-existing plaques (detected by ultrasound, CT or MRI)
- Asymptomatic major arterial stenosis
- Not being considered for arterial surgery or endovascular treatment.
You may not qualify if:
- Recurrence of cancer (with or without treatment)
- Planned surgical or endovascular intervention for revascularization of carotid arteries at the time of enrollment
- Renal failure
- Estimated glomerular filtration rate (eGFR) \< 45 (calculation based on serum creatinine levels, race, age and gender)
- Medically unstable or hematologic, renal, or hepatic dysfunction
- Non-atherosclerotic arterial stenosis (dissection)
- Presence of stents or external clips that can cause artifacts impairing accurate interpretation of MRI data
- Contraindications to MRI: cardiac pacemaker, metal implants, metal in eyes, pregnant or nursing women, claustrophobia, allergy to MRI contrast
- Physical or mental impairment that would limit the patient's ability to comply with the medical instructions or study procedures
