Cause-of-death analysis in patients with cardiac resynchronization therapy with or without a defibrillator: a systematic review and proportional meta-analysis

ConclusionOverall, compared with CRT-D patients, unadjusted mortality rate was almost two-fold higher in CRT-P recipients, with SCD representing one third of the excess mortality. Rate of SCD was significantly higher in certain subgroups (males, ischaemic cardiomyopathy, NYHA class 3), where a CRT-D may be of more pronounced benefit. This deserves further focused investigation.
