Purpose of review: In this review article we describe the cardiovascular adverse events associated with BRAF and MEK inhibitors as well as their pathophysiologic mechanisms and provide up to date guidance for risk stratified surveillance of patients on treatment and the optimal management of emergent cardiotoxicities.
Recent findings: Combination BRAF/MEK inhibition has become an established standard treatment option for patients with a wide variety of BRAF mutant haematological and solid organ cancers, its use is most commonly associated with stage three and metastatic melanoma. The introduction of these targeted drugs has significantly improved the prognosis of previously treatment resistant cancers. It is increasingly recognised that these drugs have a number of cardiovascular toxicities including left ventricular systolic dysfunction, hypertension and QTc interval prolongation. Whilst cardiotoxicity is largely reversible and manageable with medical therapy, it does limit the effective use of these highly active agents.
Keywords: BRAF inhibitors; Cardiovascular toxicity; Hypertension; Left ventricular systolic dysfunction; MEK inhibitors; Melanoma.
