Telehealth consultations in cardio-oncology

Abstract

Aim. To evaluate the role of a cardiologist in telehealth counseling of cancer patients at the federal oncology center.Material and methods. This retrospective study was conducted based on the materials of 215 telehealth consultations on cardiooncology, performed in the period from January 2019 to September 2021. Data on referrals to a cardiologist (cardio-oncologist) from various Russian regions and consultants’ answers were analyzed, taking into account the following data: region, sex, age of a patient, cancer type, stage, participation of other consultants, type of cardiovascular disease, the need for additional information and features of treatment — surgery, chemotherapy, radiation therapy. Risk was stratified based on a checklist including the main risk factors for cardiotoxicity. The recommendations of consultants for monitoring patients, as well as drug therapy prescriptions, were analyzed.Results. The most common cancer sites in patients referred for telehealth consultations on cardio-oncology were lungs, larynx and trachea, colon and rectum, kidneys and bladder, ovaries and uterus, and stomach. Cardiologists consulted together with oncologists — surgeons, medical oncologists, as well as anesthesiologists and radiation oncologists. The most common cardiovascular diseases were hypertension — 80,9% of patients, heart failure — 60%, arrhythmias — 41,6% and coronary heart disease — 37,7%. From 71 to 80,3%, 15,6-21% and 3,9-7,8% of patients had preserved, mid-range and reduced left ventricular ejection fraction. In 47,6-66,7% of cases, consultants required additional information. Based on risk stratification of cardiotoxicity of anticancer treatment, 118 (81,9%) patients out of 144 were classified as high and very high risk. Most patients were recommended cardioprotective therapy, which most often included angiotensin-converting enzyme inhibitors/angiotensin receptor blockers — 43,1-53,1%, beta-blockers — 44,8-58,6%, and statins — 22,4-38,3%. An algorithm for creating a request for a cardio-oncology telehealth consultation has been developed.Conclusion. The important role of cardio-oncology telehealth consultations in the work of the federal oncology center is demonstrated. Consulting cardiologists are part of a single multidisciplinary team of specialists and must act taking into account the characteristics of cancer and antitumor therapy prescribed by oncologists.
