Immune checkpoint inhibitor-induced myocarditis

Aim. To analyze the condition of the cardiovascular system in oncological patients receiving immune antitumor therapy with immune checkpoint inhibitors (CPIs) based on results of laboratory and instrumental examinations during a 3-month follow-up.Material and methods. This multicenter prospective observational study included 49 patients (25 men and 24 women aged 65.6±8.7 and 64.3±9.6 years, respectively). A laboratory screening (C-reactive proteins, troponin I, N-terminal pro-brain natriuretic peptide), EchoCG, and carotid ultrasound were performed for all patients. 27 patients were followed up at 3 months after the antitumor therapy initiation. Statistical analysis was performed with the StatPlus 8.0.3 software.Results. Incidence of cardiovascular complications was 16.3 %. The following significant changes in EchoCG parameters were observed: LV EF; (p=0.017), increased LV end-systolic volume (ESV) (р=0.023), and increased LV index of myocardial performance (LIMP; р=0.016). The degree of changes in ESV (ΔESV) depended on a history of chronic heart failure (р=0.03), whereas the degree of changes in EF (ΔEF) depended on the patient’s age at the initiation of antitumor therapy (р=0.006). Ultrasound showed an increase in maximum carotid stenosis (р=0.018).Conclusion. The study showed a high incidence of newly developed cardiovascular complications associated with the CPI treatment as well as the presence of changes in EchoCG parameters and data of carotid ultrasound.
