Balancing between clinical efficacy and economic expediency: choosing a device for cardiac resynchronization therapy

The article focuses on the analysis of device selection for cardiac resynchronization therapy based on the stratification of sudden cardiac death risk. Various diagnostic methods and clinical-anamnestic data are considered, along with their role in predicting arrhythmogenic events and making implantation decisions. Differences in implantation approaches for patients with ischemic and non-ischemic cardiomyopathy are discussed, emphasizing the importance of a combined risk assessment and the use of prognostic models. Unresolved issues related to optimal patient selection, timing for evaluating CRT effectiveness, and potential implantation strategies considering both economic and clinical factors are also reviewed.
