Abstract

Background: Accurate risk stratification for patients with non-dilated left ventricular cardiomyopathy (NDLVC) remains challenging due to lack of dedicated clinical trials. This post-hoc analysis aims to delineate the arrhythmic risk and assess the incremental value of cardiac magnetic resonance (CMR) imaging in the DERIVATE (CarDiac MagnEtic Resonance for Primary Prevention Implantable CardioVerter DebrillAtor ThErapy) study cohort meeting the NDLVC diagnostic criteria.

Methods: Patients with NDLVC from DERIVATE registry were identified in the absence of left ventricular (LV) dilatation and in the presence of non-ischaemic LV scarring ("fibrotic NDLVC") or isolated LV systolic dysfunction (LV ejection fraction <50%) without fibrosis ("hypokinetic NDLVC"). The primary endpoint was all-cause mortality. Major adverse arrhythmic cardiac events (MAACE) were the secondary endpoint and included sudden cardiac death (SCD) and aborted SCD.

Results: One hundred ninety-seven NDLVC patients were identified from the cohort of the DERIVATE study (Mean age: 59±14 years; Male: 135). Over a median follow-up of 2.7 years, 15 (8%) patients died, and 8 (4%) experienced MAACE. Patients with "hypokinetic" NDLVC had significantly lower rates of MAACE than non-ischaemic dilated cardiomyopathy (NIDCM) (p=0.001), while patients with "fibrotic" NDLVC had same rate of both primary (p=0.48) and secondary endpoints (p= 0.616) compared to NIDMC patients. Multivariable analysis identified LGE with midwall distribution as an independent predictor of MAACE in NDLVC patients (Hazard Ratio 6.7, 95% Confidence Interval: 1.33-33.67; p=0.021).

Conclusions: NDLVC patients exhibit a heterogeneous risk profile for arrhythmic events. The presence of midwall LGE, similarly to NIDCM, is a significant predictor of MAACE, highlighting the importance of CMR imaging for risk stratification.

期刊介绍： European Heart Journal – Cardiovascular Imaging is a monthly international peer reviewed journal dealing with Cardiovascular Imaging. It is an official publication of the European Association of Cardiovascular Imaging, a branch of the European Society of Cardiology. The journal aims to publish the highest quality material, both scientific and clinical from all areas of cardiovascular imaging including echocardiography, magnetic resonance, computed tomography, nuclear and invasive imaging. A range of article types will be considered, including original research, reviews, editorials, image focus, letters and recommendation papers from relevant groups of the European Society of Cardiology. In addition it provides a forum for the exchange of information on all aspects of cardiovascular imaging.
