OBJECTIVES: Retrospective study of oncology patients with cardiovascular event ,  in order to help an decision.   There is evidence regarding the prognosis of cancer patients, which is seen as a carrier of a chronic disease that throughout its evolution may have acute decompensation, as cardiovascular manifestations .  Progress in cancer treatment also resulted in  increased exposure of patients to cardiovascular risk factors and chemotherapy with potential cardiotoxicity  and sure for expenses in terms of adding costs of care . METHODS: We analised  68 cases collected and registered by the  time of cardiology and oncology audit , in 2012. OUTCOMES ITEMS USED : Costs , cardiovascular events associated with cancer . RESULTS: Among 68 cases , Breast Cancer is the majority accounting 32  ( 47 % ) . All of them were seen by cardiologist and the total amount spent were USD 15.000,00 .  Thirty one patients  were caracterized having a cardio - vascular event and the costs were comprise by echocardio , ergo-cardio test, angio tomography and coronary cardiac catheterization . The costs of oncology  treatment range from $1.500,00 to $ 6.800,00  USD per cicle , each 21 or 28 days , that means $ 18.000,00 to $ 120.000,00  USD a year .  It means that the provisional budget will range from $ 1.224.000,00 to $ 8.160.000,00 USD a year for the cohort of 68 patients in our  institution. So ,  we will spend 0,18 % to 1.22 % in cardiac vigilance for the oncologic patients describe above CONCLUSIONS: The costs still low, the price of the oncologic cure with an cardiologic event needs more studies, details need for further recomendations .
