Background: In patients with heart failure and preserved ejection fraction, little is known about the characteristics of, and outcomes in, those with and without diabetes mellitus.Methods: We examined clinical and echocardiographic characteristics and outcomes in the I-Preserve trial (Irbesartan in Heart Failure With Preserved Ejection Fraction) according to history of diabetes mellitus. Cox regression models were used to estimate hazard ratios for cardiovascular outcomes adjusted for known predictors, including age, sex, natriuretic peptides, and comorbidity. Echocardiographic data were available in 745 patients and were additionally adjusted for in supplementary analyses.Results: Overall, 1134 of 4128 patients (27%) had diabetes mellitus. Compared with those without diabetes mellitus, they were more likely to have a history of myocardial infarction (28% versus 22%), higher body mass index (31 versus 29 kg/m2), worse Minnesota Living With Heart Failure score (48 versus 40), higher median N-terminal pro-B-type natriuretic peptide concentration (403 versus 320 pg/mL; all P<0.01), more signs of congestion, but no significant difference in left ventricular ejection fraction. Patients with diabetes mellitus had a greater left ventricular mass and left atrial area than patients without diabetes mellitus. Doppler E-wave velocity (86 versus 76 cm/s; P<0.0001) and the E/e' ratio (11.7 versus 10.4; P=0.010) were higher in patients with diabetes mellitus. Over a median follow-up of 4.1 years, cardiovascular death or heart failure hospitalization occurred in 34% of patients with diabetes mellitus versus 22% of those without diabetes mellitus (adjusted hazard ratio, 1.75; 95% confidence interval, 1.49-2.05), and 28% versus 19% of patients with and without diabetes mellitus died (adjusted hazard ratio, 1.59; confidence interval, 1.33-1.91).Conclusions: In heart failure with preserved ejection fraction, patients with diabetes mellitus have more signs of congestion, worse quality of life, higher N-terminal pro-B-type natriuretic peptide levels, and a poorer prognosis. They also display greater structural and functional echocardiographic abnormalities. Further investigation is needed to determine the mediators of the adverse impact of diabetes mellitus on outcomes in heart failure with preserved ejection fraction and whether they are modifiable.Clinical Trial Registration: URL: http://www.clinicaltrials.gov.

Background: Return to work is important financially, as a marker of functional status and for self-esteem in patients developing chronic illness. We examined return to work after first heart failure (HF) hospitalization.Methods: By individual-level linkage of nationwide Danish registries, we identified 21 455 patients of working age (18-60 years) with a first HF hospitalization in the period from 1997 to 2012. Of these patients, 11 880 (55%) were in the workforce before HF hospitalization and comprised the study population. We applied logistic regression to estimate odds ratios for associations between age, sex, length of hospital stay, level of education, income, comorbidity, and return to work.Results: One year after first HF hospitalization, 8040 (67.7%) returned to the workforce, 2981 (25.1%) did not, 805 (6.7%) died, and 54 (0.5%) emigrated. Predictors of return to work included younger age (18-30 versus 51-60 years; odds ratio [OR], 3.12; 95% confidence interval [CI], 2.42-4.03), male sex (OR, 1.22; 95% CI, 1.12-1.34), and level of education (long-higher versus basic school; OR, 2.06; 95% CI, 1.63-2.60). Conversely, hospital stay >7 days (OR, 0.56; 95% CI, 0.51-0.62) and comorbidity including history of stroke (OR, 0.55; 95% CI, 0.45-0.69), chronic kidney disease (OR, 0.46; 95% CI, 0.36-0.59), chronic obstructive pulmonary disease (OR, 0.62; 95% CI, 0.52-0.75), diabetes mellitus (OR 0.76; 95% CI, 0.68-0.85), and cancer (OR, 0.49; 95% CI, 0.40-0.61) were all significantly associated with lower chance of return to work.Conclusions: Patients in the workforce before HF hospitalization had low mortality but high risk of detachment from the workforce 1 year later. Young age, male sex, and a higher level of education were predictors of return to work. [ABSTRACT FROM AUTHOR]

Background: Many episodes of worsening of heart failure (HF) are treated by increasing oral therapy or temporary intravenous treatment in the community or emergency department (ED), without hospital admission. We studied the frequency and prognostic importance of these episodes of worsening in the Prospective Comparison of ARNI (angiotensin-receptor-neprilysin inhibitor) with ACEI (angiotensin-converting enzyme inhibitor) to Determine Impact on Global Mortality and Morbidity in Heart Failure Trial (PARADIGM-HF).Methods and Results: Outpatient intensification of HF therapy was added to an expanded composite outcome with ED visits, HF hospitalizations, and cardiovascular deaths. In an examination of first nonfatal events, 361 of 8399 patients (4.3%) had outpatient intensification of HF therapy without a subsequent event (ie, ED visit/HF hospitalizations) within 30 days; 78 of 8399 (1.0%) had an ED visit without previous outpatient intensification of HF therapy or a subsequent event within 30 days; and 1107 of 8399 (13.2%) had HF hospitalizations without a preceding event. The risk of death (in comparison with no-event patients) was similar after each manifestation of worsening: outpatient intensification of HF therapy (hazard ratio, 4.8; 95% confidence interval, 3.9-5.9); ED visit (hazard ratio, 4.5; 95% confidence interval, 3.0-6.7); HF hospitalizations (hazard ratio, 5.9; 95% confidence interval, 5.2-6.6). The expanded composite added 14% more events and shortened time to accrual of a fixed number of events. The benefit of sacubitril/valsartan over enalapril was similar to the primary outcome for the expanded composite (hazard ratio, 0.79; 95% confidence interval, 0.73-0.86) and was consistent across the components of the latter.Conclusions: Focusing only on HF hospitalizations underestimates the frequency of worsening and the serious implications of all manifestations of worsening. For clinical trials conducted in an era of heightened efforts to avoid HF hospitalizations, inclusion of episodes of outpatient treatment intensification (and ED visits) in a composite outcome adds an important number of events and shortens the time taken to accrue a target number of end points in an event-driven trial.Clinical Trial Registration: URL: http://www.clinicaltrials.gov.

Background--High-sensitivity troponin-I (hs-TnI) measurement improves risk assessment for cardiovascular events in many clinical settings, but the added value in atrial fibrillation patients has not been described. Methods and Results--At randomization, hs-TnI was analyzed in 14 821 atrial fibrillation patients in the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation (ARISTOTLE) trial comparing apixaban with warfarin. The associations between hs-TnI concentrations and clinical outcomes were evaluated by using adjusted Cox analysis. The hs-TnI assay detected troponin (≥1.3 ng/L) in 98.5% patients, 50% had levels >5.4, 25% had levels >10.1, and 9.2% had levels ≥23 ng/L (the 99th percentile in healthy individuals). During a median of 1.9 years follow-up, annual rates of stroke or systemic embolism ranged from 0.76% in the lowest hs-TnI quartile to 2.26% in the highest quartile (>10.1 ng/L). In multivariable analysis, hs-TnI was significantly associated with stroke or systemic embolism, adjusted hazard ratio 1.98 (1.42-2.78), P=0.0007. hs-TnI was also significantly associated with cardiac death; annual rates ranged from 0.40% to 4.24%, hazard ratio 4.52 (3.05-6.70), P<0.0001, in the corresponding groups, and for major bleeding hazard ratio 1.44 (1.11-1.86), P=0.0250. Adding hs-TnI levels to the CHA2DS2VASc score improved c-statistics from 0.629 to 0.653 for stroke or systemic embolism, and from 0.591 to 0.731 for cardiac death. There were no significant interactions with study treatment. Conclusions--Troponin-I is detected in 98.5% and elevated in 9.2% of atrial fibrillation patients. The hs-TnI level is independently associated with a raised risk of stroke, cardiac death, and major bleeding and improves risk stratification beyond the CHA2DS2VASc score. The benefits of apixaban in comparison with warfarin are consistent regardless of hs-TnI levels. Clinical Trial Registration--URL: http://www.clinicaltrials.gov. Unique identifier: NCT00412984.
