Onco-cardiology: Present and future.

"Onco-cardiology" is a term that indicates cardiotoxicity during treatment of malignant diseases. Many studies have demonstrated that chemotherapy agents induce cardiotoxicity in certain ratios. In clinical settings, active malignant diseases or a history thereof are often encountered in patients with cardiovascular disease (CVD); it is not uncommon for a patient to struggle with a prior treatment. We have previously demonstrated a close association between malignant diseases and coronary calcifications in coronary artery disease. The concurrence of arteriosclerotic diseases, including CVD, with malignant diseases should be carefully considered in clinical settings, particularly with regard to scheduled surgical procedures. Moreover, it is essential that all medical professionals associated with cancer care understand these associations. Our advocacy will provide new insight into onco-cardiology.
