Efficacy and safety of cardiac resynchronization therapy in chemotherapy‐induced cardiomyopathy: A systematic review

OBJECTIVE: The aim of the study was to assess the efficacy of cardiac resynchronization therapy (CRT) in patients with chemotherapy‐induced cardiomyopathy (CIC). METHODS: With the increasing incidence of CIC, the association of CRT with improvement in clinical outcomes, echocardiographic parameters, and New York Heart Classification (NYHA) class was assessed through this qualitative systematic review. RESULTS: The five studies included a total of 169 patients who underwent CRT after CIC, and of these, 61 (36.1%) patients were males. All studies showed an improvement in left ventricular ejection fraction (LVEF), among other echocardiographic parameters of LV volume. However, these findings are limited by short follow‐up periods, small sample sizes, and the absence of a control group. CONCLUSION: CRT was associated with improvement in all patient parameters with CIC.
