Introduction: Myocardial scar is associated with a higher prevalence of ventricular arrhythmias (VA) and sudden cardiac death (SCD). Late gadolinium enhancement cardiovascular magnetic resonance (LGE-CMR) can accurately evaluate the extent of myocardial scar. Clinical evidence suggests that scar assessment may help the decision of adding an implantable cardioverter defibrillator (ICD) to cardiac resynchronization therapy (CRT) to reduce the risk of VA and SCD.
Aims: In this systematic review and meta-analysis, we investigate the association between scar burden and SCD risk in cardiac resynchronization therapy patients.
Method: We performed a systematic literature search on MEDLINE using the PubMed, Embase, Scopus, and CENTRAL databases. The target population was patients with heart failure with reduced ejection fraction who underwent CRT. The primary endpoint was appropriate ICD shock. Meta-analyses were performed using the META and DMETAR packages in R, using a random-effects model. The risk of bias was assessed using RoB2 and the quality of evidence was evaluated using the GRADE assessment.
Results: Altogether 16 eligible articles have been included in our study, with a total of 2624 patients, of whom 601, 1220, and 391 have been implanted with an ICD, CRT-D, CRT-P respectively. Altogether 56 % of the total population were LGE-CMR positive, The proportion of appropriate ICD shock reached 18,58 % in the total population during the median follow-up time of 44 months.
The risk of developing sudden cardiac death events in the LGE positive population in articles using competing risk models was almost 48% higher (Hazard ratio 1,48, 95% Confidence interval: 0,75- 2,92) compared to LGE negative patients.
Conclusion: In our meta-analysis, LGE-CMR was associated with a trend toward appropriate device therapy and can identify a subgroup of patients with an increased risk of sudden cardiac death events. Based on our results performing an MRI before device implantation might be important to select the high-risk patients for SCD.
