Identifying independent risk factors of mortality among patients receiving a leadless pacemaker: A longitudinal retrospective study in a single center

CCI has previously been demonstrated to be a significant predictor of mortality in patients receiving pacemakers or implantable defibrillators. In our study, we found that a CCI of >4 was independently associated with mortality. In addition, our study highlights that low left ventricular ejection fraction, hemoglobin, and advanced age are key risk factors that may predict early mortality among LP patients.
