Long-term clinical outcomes after upgrade to resynchronization therapy: A propensity score-matched analysis.

ABSTRACT:

Background

Upgrade to cardiac resynchronization therapy (CRT) is common in Europe, despite little and conflicting evidence.

Objective

To compare long-term clinical outcomes in a cohort of patients receiving de novo or upgrade to CRT.

Methods

Single-center retrospective study of 295 consecutive patients submitted to CRT implantation between 2007 and 2018. Upgraded and de novo patients complying with a dedicated follow-up protocol were compared in terms of clinical (NYHA class improvement without major adverse cardiac events [MACE] in the first year of follow-up) and echocardiographic (left ventricle end-systolic volume reduction of >15% during the first year) response.

Results

No differences in the rate of clinical (59.3% vs 62.6%, P = .765) or echocardio
