Cardio-oncology is the cardiac care of cancer patients. Cardiac issues may develop during cancer treatment or may be pre-existing or may develop as late effects. There has been increasing recognition of these issues recently which has led to the development of the new sub-speciality of cardio-oncology bringing together cardiologists, oncologists and allied healthcare professionals.

This Cardio-oncology section showcases key papers in the field to allow readers to quickly familiarise themselves with the latest advances in this rapidly developing field. There will be work related to the different cardiac complications of cancer treatment e.g. acute coronary syndromes, myocarditis, heart failure and arrhythmias. Research focussing on specific cancer therapies and their cardiotoxicities will also be featured e.g. immunotherapies, targeted therapies, cytotoxic drugs, radiotherapy etc. Finally this section will enable the reader to reference the most up-to-date guidelines in the field from national and international organisations.
