Background - Cardiac troponins are emerging as important prognostic markers in chronic cardiovascular conditions like stable coronary artery disease or chronic heart failure (HF). Less is known about the relation between serial measurements of high-sensitivity cardiac troponin T (hs-cTnT) and future events in HF. We determined the association between changes over time in hs-cTnT and outcome in patients with chronic HF. Methods and Results - We analyzed 5284 patients with chronic HF from 2 independent randomized clinical trials, the Valsartan Heart Failure Trial (Val-HeFT) (n=4053) and the Gruppo Italiano per lo Studio della Sopravvivenza nell'Insufficienza Cardiaca-Heart Failure (GISSI-HF) trial (n=1231). hs-cTnT was measured at randomization and after 3 months (GISSI-HF) or 4 months of follow-up (Val-HeFT). The association between changes over time of hs-cTnT and various outcomes was tested in multivariable models. In both studies, increases in hs-cTnT levels over time were associated with age, diabetes mellitus, worsening of renal function (reduction in estimated glomerular filtration rate), and baseline and increases in N-terminal pro-brain natriuretic peptide concentrations. Increases in hs-cTnT concentrations were associated with all-cause mortality (incidence rates, 8.19 [7.51-8.88] and 6.79 [5.98-7.61] per 100 person-years in Val-HeFT and GISSI-HF, respectively, with hazard ratios [95% confidence intervals] of 1.59 [1.39-1.82] and 1.88 [1.50-2.35]) after adjustment for conventional risk factors and baseline levels of hs-cTnT and N-terminal pro-brain natriuretic peptide. Changes in hs-cTnT concentration modestly improved prognostic discrimination beyond baseline values for fatal outcomes only. Conclusions - Despite very low circulating concentrations, changes in hs-cTnT concentrations over time are robust predictors of future cardiovascular events in patients with chronic HF but add limited prognostic discrimination. © 2011 American Heart Association, Inc.

Aims Registries and surveys improve knowledge of the 'real world'. This paper Aims to describe baseline clinical profiles, management strategies, and the in-hospital outcome of patients admitted to hospital for an acute heart failure (AHF) episode.Methods and resultsIN-HF Outcome is a nationwide, prospective, multicentre, observational study conducted in 61 Cardiology Centres in Italy. Up to December 2009, 5610 patients had been enrolled, 1855 (33) with AHF and 3755 (67) with chronic heart failure (CHF). Baseline and in-hospital outcome data of AHF patients are presented. Mean age was 72 ± 12 years, and 39.8 were female. Hospital admission was due to new-onset heart failure (HF) in 43 of cases. Co-morbid conditions were observed more frequently in the worsening HF group, while those with de novo HF showed a higher heart rate, blood pressure, and more preserved left ventricular ejection fraction (LVEF). Electrical devices were previously implanted in 13.3 of the entire group. Inotropes were administered in 19.4 of the patients. The median duration of hospital stay was 10 days (interquartile range 7-15). All-cause in-hospital death was 6.4, similar in worsening and de novo HF. Older age, hypotension, cardiogenic shock, pulmonary oedema, symptoms of hypoperfusion, hyponatraemia, and elevated creatinine were independent predictors of all-cause death.ConclusionOur registry confirms that in-hospital mortality in AHF is still high, with a long length of stay. Pharmacological treatment seems to be practically unchanged in the last decades, and the adherence to HF guidelines concerning implantable cardioverter defibrillators/cardiac resynchronization therapy is still very low. Some AHF phenotypes are characterized by worst prognosis and need specific research projects. © 2012 The Author. Source

Aims: A recent randomized placebo-controlled clinical trial has reported reductions in mortality and hospitalizations in patients with chronic heart failure (CHF) who were prescribed highly purified omega-3 polyunsaturated fatty acid ethyl esters (n-3 PUFA). This study aimed at evaluating the cost and benefits associated with their use in the treatment of CHF in a UK setting.Methods and resultsResults from a recent clinical trial were used to develop a Markov model to project clinical outcomes while capturing relevant costs and patient quality of life. The model captured outcomes over a lifetime horizon from a UK National Health Service perspective, with direct costs accounted in 2009 GBP (£) and discounted at 3.5 together with clinical benefits. Results are presented in terms of life expectancy, quality-adjusted life expectancy, direct costs, and incremental cost-effectiveness ratios. In addition to standard therapy, n-3 PUFA vs. placebo increased lifetime direct costs by £993 (≈€1150), with additional quality-adjusted life expectancy of 0.079 quality-adjusted life years (QALYs), and mean lifetime costs of £12 636 (≈€14 600) per QALY gained. Probabilistic sensitivity analyses suggested a 60 likelihood of n-3 PUFA being regarded as cost-effective versus placebo at a willingness-to-pay threshold of £30 000 (≈€34 600) per QALY gained.ConclusionsBy currently accepted standards of value for money in the UK; the addition of n-3 PUFA to optimal medical therapy for patients with heart failure is likely to be cost-effective. © 2011 The Author.

Background.Clinical observational studies on heart failure (HF) deal mostly with hospitalized patients, few with chronic outpatients, all with no or limited longitudinal observation. Methods and Results.This is a multicenter, nationwide, prospective observational trial on a population of 5610 patients, 1855 hospitalized for acute HF (AHF) and 3755 outpatients with chronic HF (CHF), followed up for 1 year. The cumulative total mortality rate at 1 year was 24% in AHF (19.2% in 797 patients with de novo HF and 27.7% in 1058 with worsening HF) and 5.9% in CHF. Cardiovascular deaths accounted for 73.1% and 65.3% and HF deaths for 42.4% and 40.5% of total deaths in AHF and CHF patients, respectively. One-year hospitalization rates were 30.7% in AHF and 22.7% in CHF patients. Among the independent predictors of 1-year all-cause death, age, low systolic blood pressure, anemia, and renal dysfunction were identified in both acute and chronic patients. A few additional variables were significant only in AHF (signs of cerebral hypoperfusion, low serum sodium, chronic obstructive pulmonary disease, and acute pulmonary edema), whereas others were observed only in CHF patients (lower body mass index, higher heart rate, New York Heart Association class, large QRS, and severe mitral regurgitation). Conclusions.In this contemporary data set, patients with CHF had a relatively low mortality rate compared with those with AHF. Rates of adverse outcomes in patients admitted for AHF remain very high either in-hospital or after discharge. Most deaths were cardiovascular in origin and .40% of deaths were directly related to HF. © 2013 American Heart Association, Inc. Source

Aims: Elevated heart rate is a significant marker for mortality and morbidity in cardiovascular disease including heart failure. Despite background treatment with a beta-blocker, many patients with heart failure and low ejection fraction maintain a heart rate above 70 b.p.m. Ivabradine reduces heart rate directly through inhibition of the If ionic current.MethodsSHIFT is a randomized, double-blind study designed to compare ivabradine with placebo on outcomes in patients with symptomatic chronic heart failure (NYHA class II-IV), left-ventricular ejection fraction ≤35, and a prior hospitalization for worsening heart failure within the previous 12 months. Randomized treatment is given on top of guidelines-based therapy for chronic heart failure, including a beta-blocker at optimized dose. Resting heart rate at baseline must be ≥70 b.p.m. The primary endpoint is the composite of the time to first event of cardiovascular death or hospitalization for worsening heart failure. Secondary endpoints include all-cause, cardiovascular and heart failure mortality, and hospitalization. The randomized treatment period lasts approximately 12-48 months. The study will include approximately 6500 patients and will continue until ≥1600 primary endpoints have occurred. The first patient was randomized in October 2006, and the study is expected to end in 2010.ConclusionThe SHIFT study will assess if a heart rate reduction by direct sinus node inhibition can reduce cardiovascular outcomes in patients with chronic heart failure and left-ventricular systolic dysfunction.
