Cardio-oncology discipline: focus on the necessities in developing countries

Cardiovascular diseases constitute one of the main aetiologies of mortality among patients with cancer. Population ageing and cancer survival rate improvements have resulted in the coexistence of cardiovascular diseases and malignancies in an increasing number of patients. With the diversity in treatments and the introduction of new drug lines, multiple mechanisms of cardiovascular injury have been recognized in these patients. Cardio-oncology is an emerging entity introduced to provide a proper solution to the several challenges encountered in the management of patients with cancer and cardiac involvement. This review will assess the logical grounds for establishing a cardio-oncology unit, describe the main objectives and the detailed responsibilities in such systems, and outline the target population. Furthermore, the importance of research and appropriate data collection will be highlighted. Lastly, the special considerations and modifications required for setting up such centres in the developing countries are discussed.
