Redictive factor of lethal arrhythmias in uremic patients [40]. Of note, patients with ventricular arrhythmia in the present study had higher left ventricular mass index and a higher frequency of left ventricular hypertrophy. It has been already established that coronary artery calcification is highly prevalent in dialysis patients as well as in nondialyzed CKD patients [41?4]. Not surprisingly, a high prevalence of coronary artery calcification was found in our study sample. We have previously demonstrated the straight association between vascular calcification and cardiovascular events in nondialyzed CKD 1317923 patients [45], which is in line with the finding by other investigators [46,47]. In the current study, coronary calcium score and the frequency of coronary artery calcification were both higher among patients with ventricular arrhythmia, when compared to those without this cardiac complication. The inhibitor impact of the presence of ventricular arrhythmia on hard outcomes remains to be further investigated. There is evidence in the literature that the inhibitor protein-energy malnutrition might increases the risk of prolonged QT interval, ventricular arrhythmias and sudden death [48]. The only measure that could support this rationale herein is the lower triglycerides level found in the group of patients with ventricular arrhythmia. However, since only 4 of the patients in the current study were malnourished according to the subjective global assessment, this supposition is unlikely in this study. Another explanation for the lower triglycerides in the group with arrhythmias could be thatVentricular Arrhythmia in CKD PatientsTable 2.
