摘要

Chemotherapy-induced cardiomyopathy (CHIC) represents a growing clinical challenge due to the increasing use of cardiotoxic treatments. These therapies can lead to progressive myocardial dysfunction, ultimately resulting in heart failure. Cardiac resynchronization therapy (CRT) has been widely investigated in selected patients with chronic heart failure; however, those with CHIC remain underrepresented in CRT trials. Current evidence is largely based on retrospective and observational studies, with MADIT-CHIC being the only prospective trial to date. No randomized controlled trials are currently available. Despite encouraging findings, existing data remain limited by small sample sizes and short follow-up durations. In particular, the impact of CRT on left ventricular dyssynchrony, arrhythmic burden, and long-term survival in this population has not been fully elucidated. A multidisciplinary cardio-oncology approach is essential not only for the comprehensive management of these complex patients, but also to guide appropriate timing of CRT implantation. Further research is warranted to refine patient selection criteria and to fully assess the long-term benefits and risks of CRT in patients with CHIC.
