Removal of these autoantibodies improved haemodynamic parameters and left ventricular ejection fraction patients with CHF. The goal of this project is to evaluate whether beta1-AAbs and M2-AAbs predict prognosis and sudden cardiac death (SCD) in CHF.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and results<\/jats:title>\n                    <jats:p>A total of 2062 patients with CHF and 824 control subjects were recruited. Beta1-AAbs and M2-AAbs were detected by the enzyme-linked immunosorbent assay (ELISA) method, and the correlation between these autoantibodies and the prognosis of CHF was analysed. During a median follow-up period of 36 months (0.40 \u00b1 65 months), 379 (21.56%) cases died\u2014164 had dilated cardiomyopathy (DCM) and 215 had ischaemic cardiomyopathy (ICM). Of these, SCD occurred in 69 cases (40.37%) of DCM and in 84 cases (39.07%) of ICM. Positivity for beta1-AAbs in DCM and ICM was significantly higher than for the controls (8.1% and 8.25% v.s 2.2%, both P &amp;lt; 0.01). However, positive M2-AAbs did not show any statistical difference between the three groups. Cox regression analysis revealed that positive beta1-AAbs were associated with higher mortality in CHF and that it predicted SCD for DCM [hazard ratio (HR) 4.51, 95% confidence interval (CI) 2.405\u20138.471] and ICM (HR 3.749, 95% CI 2.389\u20135.884) patients, but not non-SCD (NSCD) patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The rates of positive beta1-AAbs were higher in CHF patients than in the controls.
