Coronary heart disease (CAD) and cancer are the two leading causes of morbidity and mortality worldwide. It is estimated that more than 50% of patients with cancer are treated with radiotherapy. Th e prognosis of many cancer has improved and increasing number of patients now go on to live an active and normal adult life, as evident by an increasing number of cancer survivors. Due to improvement in radiation technique the risk of cardiovascular complications in relation to radiation may have declined over time, but even in patients treated as lately as between 1979-1986 the risk congestive heart failure and valvular dysfunction remained increased. Mediastinal radiation causes a wide spectrum of disease involving the pericardium, valves, myocardium and coronary vessels, resulting in pericarditis, valvular disease, cardiomyopathy and pre- mature accelerated coronary atherosclerosis. Asymptomatic CAD is also prevalent in this patient population, with perfusion abnormalities developing in 27% of patients at 6 months of radiation therapy. Due to small number of patients and short duration of follow up, the long term consequence of these perfusion defects is not known. With improvement in radiation techniques, the cardiovascular aff ects my decrease over time. However these new techniques may not be available in less privileged countries for many years, exposing million of patients to current radiation techniques. Hence as such the emphasis should be on prevention, early detection and aggressive treatment of concomitant cardiovascular risk factors.
