A significant association between CC-AAbs and non-SCD (NSCD) was found in ICM patients (HR = 1.887, 95% CI 1.081C3.293). Our results demonstrated that the presence of CC-AAbs was higher in CHF patients versus controls and corresponds to a higher incidence of all-cause death and Mcl-1-PUMA Modulator-8 SCD. Positive CC-AAbs may serve as an independent predictor for SCD and all-cause death in these patients. 1. Introduction Chronic heart failure (CHF) evolves in the setting of left ventricular systolic and/or diastolic dysfunction and is a serious public health problem worldwide with increasing prevalence [1]. Long-term prognosis of CHF is usually poor and over 50% of CHF patients pass away within 5 years after diagnosis [2]. A major cause of mortality is sudden cardiac death (SCD) from ventricular arrhythmias [3, 4]. Thus, prediction and prevention of SCD are crucial to management of these patients. Recently, evidence has been accumulating suggesting that autoimmunity plays a role in the occurrence and progression of CHF [5C7]. For example, = 6), whereas the intermicrotiter plate CV level was obtained from different plates. The CVs of intraplates were less than 5%, and CVs of the interplates were less than 10%. 2.5. End Point Assessment The patients were followed up to the end of March 2013 during regular outpatient medical center or through telephone contact. Median follow-up period was 52 months (0.40~92??months). End points included all-cause death, SCD (ICD appropriate discharge counter as SCD), and NSCD (heart transplantation regarded as NSCD). SCD was defined as unexpected death within 1 hour of onset of acute symptoms or unwitnessed death such as during sleep or unexpected death of someone last seen in stable medical condition 24?h with no evidence of a noncardiac Mcl-1-PUMA Modulator-8 cause [20]. 2.6. Statistical Analysis Statistical analyses were performed using SPSS 21.0 software (SPSS Inc, Chicago). Continuous values were expressed as mean??SD, and categorical variables were shown as figures (%). Student’s 0.05 was considered significant. Person-months of follow-up period started from your date of enrollment to the end of March 2013. Survival analysis in CHF patients was performed. 265 (12.64%) patients were lost to follow up and excluded in survival analysis. Kaplan-Meier curves using log rank test were performed based on presence or absence of CC-AAbs. By using Cox regression, the hazard ratios for time to all-cause death, SCD, and non-SCD from baseline were evaluated. 3. Results 3.1. Clinical Characteristics A total of 1831 CHF patients (732 cases of DCM and 1099 cases of ICM) were successfully followed. As shown in Table 1, age and body mass index (BMI) distribution did not differ between CHF patients and controls ( 0.05). Other possible CHF risk factors such as hypertension, hyperlipidemia, diabetes mellitus, early ventricular contractions (PVCs), atrial fibrillation (AF), suggest heartrate (MHR), LVEF, and remaining ventricular end-diastolic size (LVEDD) had been more frequent in CHF individuals than in settings ( 0.05).
