Cardiovascular disease (CVD) and cancer are the leading causes of suffering and death amongst the American population. While an ever-increasing number of cancer survivors have a favorable outcome due to advances in cancer treatment; cancer survivors remain at high risk of developing CVD at an early age. There is scant information available on the pathogenic process that contributes to cardiovascular threat amongst cancer survivors and little is known about the interventions, which may interrupt or decrease the risk of CVD in this population. Importantly, early-subclinical markers may substantially precede clinical markers. The objective of this project is to accurately determine the constituents and characteristics of atherosclerotic plaques in carotid arteries by magnetic resonance imaging (MRI) techniques in cancer survivors; at different data intervals: before and after administration of treatment (medical and life style modification) and then correlate contrast agent dynamics with serum markers of inflammation and other tests of cardiac or vascular dysfunction, where available. The proposed study involves 100 asymptomatic patients who received prior chest or head and neck radiation therapy (HNXRT) as part of cancer treatment. MRI data (direct assessment of atherosclerosis) would be correlated with indirect measures of atherosclerosis (blood surrogate markers & metabolomics). The investigators intend to conduct an initial baseline MRI, blood tests (to correlate with surrogate markers of inflammation) and other tests whenever available of cardiac or vascular dysfunction. This cohort will be followed up with medication and/or life style modification regimen for a period of initially18 months and subsequently at 36 months. A repeat of all baseline studies (MRI and blood tests) would be performed as part of the 18 and 36-month follow-up. The plaque characteristics found at MRI will be correlated with results of blood tests (baseline, 18 and 36 months) and changes in one or both will be the expected end point of the study.
