Cancer therapy-induced left ventricular dysfunction: interventions and prognosis. Journal of cardiac failure Thakur, A., Witteles, R. M. 2014; 20 (3): 155-158


For multiple chemotherapeutics, cardiotoxicity is dose limiting and can lead to substantial morbidity and mortality. Early cardiac intervention has the potential to positively affect clinical course.We reviewed 247 consecutive patients referred to the Stanford cardiology clinic for cancer therapy-associated cardiac abnormalities from 2004 to 2012. A comprehensive review of records was performed, with documentation of baseline characteristics, cardiac imaging, medications, and clinical course. Seventy-nine patients who had left ventricular ejection fraction (LVEF) declines temporally associated with cancer therapy were included. The most common malignancies were breast (46%) and hematologic (35%); 71% of the patients were female, and overall mean age was 52 years. The primary cancer therapeutics associated with LVEF decline included anthracyclines, trastuzumab, and tyrosine kinase inhibitors. The mean LVEF was 60% before cancer therapy and 40% after cancer therapy. The most common cardiac interventions included beta-blockers (84%) and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (83%). Mean LVEF after cardiac intervention rose to 53%; 77% of patients had LVEF recovery to =50%, and 68% of these patients had recovery within 6 months of starting cardiac therapy; 76% of patients were able to continue their planned cancer therapy.With appropriate cardiac intervention, the majority of patients with LVEF decline from cancer therapy can achieve LVEF recovery and complete their cancer therapy.
