Cardiovascular Toxicity Induced by Vascular Endothelial Growth Factor Inhibitors

Abstract

Cardiotoxicity is an important side effect of vascular endothelial growth factor (VEGF) inhibitors therapy used in the treatment of various malignancies, leading to increased morbidity and mortality. Arterial hypertension, cardiac ischemia with the acceleration of atherosclerosis, arrhythmias, myocardial dysfunction and thromboembolic disease are the most feared cardiovascular adverse reactions due to VEGF inhibitors. Susceptibility for the occurrence of VEGF inhibitors-induced cardiotoxicity has multifactorial determinants, with a significant inter-individual variation. Baseline cardiovascular risk assessment of the patient, type and stage of cancer, dose and duration of VEGF inhibitors treatment and adjuvant chemotherapy or radiotherapy are the main predictors for cardiotoxicity. The role of the cardio-oncology team becomes essential for achieving maximum therapeutic anti-angiogenic effects with minimum cardiovascular side effects. This review will summarize the incidence, risk factors, mechanisms, management and treatment of VEGF inhibitors-induced cardiovascular toxicity.
