[OBJECTIVE] Onco-cardiology services are expanding rapidly in Japan. To provide a better service, it is important to consider the needs of oncologists. However, little is known regarding specific needs for which oncologists should consult cardiologists to manage cardiovascular problems of their patients.

[METHOD] We retrospectively investigated consecutive 2064 cardiology consultations of cancer patients in the University of Tsukuba Hospital, Tsukuba, Japan, between January 2014 and December 2018.

Among the 361 consultations before the administration of anticancer drugs, 235 (65.1%) were for anthracycline-based regimens. There were 506 (24.5%) consultations for the management of cardiovascular emergencies developing after the commencement of cancer treatment; venous thromboembolism was the most frequent (n = 125; 24.7%), followed by atrial fibrillation (n = 110;
