Abstract

Since major trials focus on ischemic cardiomyopathy, identifying predictors specific to DCM is crucial.</span></span></span></p> <p style="text-align:justify"><span style="font-size:12pt"><span style="font-family:"Times New Roman",serif"><strong><span style="font-family:"Arial",sans-serif">Methods and purpose:</span></strong><span style="font-family:"Arial",sans-serif"> We performed a single-centre retrospective, observational study reviewing patients with DCM</span><span style="font-family:"Arial",sans-serif"> who received cardiac implantable electronic devices (CIED) between May 2014 - October 2018 to evaluate sustained ventricular arrhythmias and associated factors, using clinical records and SPSS software for analysis. </span></span></span></p> <p style="text-align:justify"><span style="font-size:12pt"><span style="font-family:"Times New Roman",serif"><strong><span style="font-family:"Arial",sans-serif">Results: </span></strong><span style="font-family:"Arial",sans-serif">A total of 100 patients were included. </span><span style="font-family:"Arial",sans-serif">Seventy-four percent of patients were men. </span><span style="font-family:"Arial",sans-serif">Sixty-six patients had a CRT (cardiac resynchronization therapy)-defibrillator, 18 patients had a CRT-pacemaker, and 16 patients had an ICD (implantable cardioverter-defibrillator). Ninety-three percent of patients implanted the device as primary prevention and 7% as secondary prevention. Seventy-eight</span><span style="font-family:"Arial",sans-serif"> patients had arterial hypertension (HTN) and 23 presented diabetes <em>mellitus </em>(DM). At the time of device implantation, 45 patients had atrial fibrillation (AF) and by the end of follow up, that number raised to 65. During a follow-up time of 6.80±3.55 years, 33 patients presented at least one sustained VA detected by the device: 21 patients presented only ventricular tachycardia events, 2 experienced only ventricular fibrillation events and 10 had both events. Patients were divided in VA group and non-VA group. No differences were found related to age (65.36±2.16 in the VA group versus (<em>vs</em>) 67.30±1.23 years, p=0.407). The median creatinine levels were the same across groups </span><span style="font-family:Symbol">[</span><span style="font-family:"Arial",sans-serif">1.22 (IQR 0.49) in the VA <em>vs</em> 1.09 (IQR 0.57) mg/dl, p=0.361</span><span style="font-family:Symbol">]</span><span style="font-family:"Arial",sans-serif">. Patients that presented VA had significantly higher values of left ventricular end-diastolic diameter (LVEDD): 70 (IQR 9)<em> vs </em>66 (IQR 13) mm, p=0.029; but no differences when it came to left ventricular end-systolic diameter (LVESD): 58.73±1.41 mm in the AV group <em>vs</em> 55.26±1.20 mm, p=0.096. Left ventricular ejection fraction (LVEF) was the same among groups: 30 (IQR 9) %, p=0.919. </span><span style="font-family:"Arial",sans-serif">There were no association between HTN (p=0.347), DM (p=0.515) or AF at the time of device implantation (p=0.351) and the occurrence of VA events. Although by the end of follow up, 25 of the 33 patients in the VA group had atrial fibrillation, that wasn´t statistically significant (p=0.308). </span></span></span></p> <p style="text-align:justify"><span style="font-size:12pt"><span style="font-family:"Times New Roman",serif"><strong><span style="font-family:"Arial",sans-serif">Conclusion: </span></strong><span style="font-family:"Arial",sans-serif">In patients with DCM undergoing CIED implantation, sustained AV was linked to increased LVEDD, while no significant association was observed with LVEF. </span></span></span></p>
