- Background The incremental prognostic value of high-sensitive troponin T (hs-cTnT) in heart failure (HF) beyond that of high-sensitivity C-reactive protein and amino-terminal probrain natriuretic peptide is debated. We examined the prognostic value of hs-cTnT in a subgroup of patients from the Controlled Rosuvastatin Multinational Trial in HF (CORONA) study. Methods and Results Hs-cTnT as a risk factor for the primary end point (cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke; n=356), as well as all-cause mortality (n=366), cardiovascular mortality (n=299), and the composite of cardiovascular mortality and hospitalization from worsening of HF (n=465), was investigated in 1245 patients (60 years; New York Heart Association [NYHA] class II-IV, ischemic systolic HF) randomly assigned to 10 mg rosuvastatin or placebo. In multivariable analyses, adjusting for left ventricular ejection fraction, NYHA class, age, body mass index, diabetes mellitus, sex, intermittent claudication, heart rate, estimated glomerular filtration rate, apolipoprotein B/apolipoprotein A-1 ratio, amino-terminal probrain natriuretic peptide, high-sensitivity C-reactive protein, and hs-cTnT (both dichotomized according to the 99th percentile and as a continuous variable) was associated with all end points (primary end point: hazard ratio, 1.87 and 1.51, respectively, per SD change; P<0.001; all other end points: hazard ratio, 1.39-1.70). However, improved discrimination as assessed by C-statistics was only seen for the primary end point and all-cause mortality. Conclusions Elevated hs-cTnT levels provide strong and independent prognostic information in older patients with chronic ischemic HF. Clinical Trial Registration URL: http://www.clinicaltrials.gov. Unique identifier: NCT00206310.

Beneficial effect on cardiac function by intravenous immunoglobulin treatment in patients with dilated cardiomyopathy is not due to neutralization of anti-receptor autoantibody

- Anti-beta1-adrenoceptor (beta1AR) autoantibodies have been shown to be pathophysiologically important in idiopathic dilated cardiomyopathy (DCM). Treatment with intravenous immunoglobulin (IVIG) has shown beneficial effects in both DCM and ischemic cardiomyopathy. However, the underlying mechanism has not been clarified. In the present study, we therefore examined whether the improvement of cardiac function was due to neutralization of functional beta1AR autoantibodies by anti-idiotypic antibodies. Autoantibodies against the beta1AR was analysed in sera from patients with DCM and coronary artery disease (CAD) treated with IVIG or placebo before, 6 and 12 months. Six month after treatment, DCM patients showed increase in beta1AR autoantibodies, mostly in IgG1 and IgG2, whereas in CAD patients mostly in IgG2. No changes in beta1AR autoantibodies after 12 months were detected. In summary, our results indicate that improvement of cardiac function by IVIG is not due to neutralization of beta1AR autoantibodies.
