Dapagliflozin and Days of Full Health Lost in the DAPA-HF Trial.

BACKGROUND: Conventional time-to-first-event analyses cannot incorporate recurrent hospitalizations and patient well-being in a single outcome. OBJECTIVES: To overcome this limitation, we tested an integrated measure that includes days lost from death and hospitalization, and additional days of full health lost through diminished well-being. METHODS: The effect of dapagliflozin on this integrated measure was assessed in the DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure) trial, which examined the efficacy of dapagliflozin, compared with placebo, in patients with NYHA functional class II to IV heart failure and a left ventricular ejection fraction ≤40%. RESULTS: Over 360 days, patients in the dapagliflozin group (n = 2,127) lost 10.6 ± 1.0 (2.9%) of potential follow-up days through cardiovascular death and heart failure hospitalization, compared with 14.4 ± 1.0 days (4.0%) in the placebo group (n = 2,108), and this component of all measures of days lost accounted for the greatest between-treatment difference (-3.8 days [95% CI: -6.6 to -1.0 days]). Patients receiving dapagliflozin also had fewer days lost to death and hospitalization from all causes vs placebo (15.5 ± 1.1 days [4.3%] vs 20.3 ± 1.1 days [5.6%]). When additional days of full health lost (ie, adjusted for Kansas City Cardiomyopathy Questionnaire-overall summary score) were added, total days lost were 110.6 ± 1.6 days (30.7%) with dapagliflozin vs 116.9 ± 1.6 days (32.5%) with placebo. The difference in all measures between the 2 groups increased over time (ie, days lost by death and hospitalization -0.9 days [-0.7%] at 120 days, -2.3 days [-1.0%] at 240 days, and -4.8 days [-1.3%] at 360 days). CONCLUSIONS: Dapagliflozin reduced the total days of potential full health lost due to death, hospitalizations, and impaired well-being, and this benefit increased over time during the first year.

Direct and indirect costs of heart failure in relation to diabetes status - A nationwide study.

BACKGROUND AND AIM: Heart failure (HF) and diabetes mellitus (DM) are burdensome chronic diseases with high lifetime risks and numerous studies indicate associations between HF and DM. The objective of this study was to investigate the direct and indirect costs of HF patients with and without DM. METHODS AND RESULTS: Patients with a first-time diagnosis of HF from 1998 to 2016 were identified through nationwide Danish registries and stratified according to DM status into HF with or without DM. The economic healthcare cost analysis was based on both direct costs, including hospitalization, procedures, medication and indirect costs including social welfare and lost productivity. The economic burden was investigated prior to, at, and following diagnosis of HF. Patients with concomitant HF and DM were younger (median age 74 vs. 77), had more comorbidities and fewer were female as compared to patients with HF but without DM. The socioeconomic burden of concomitant HF and DM compared to HF alone was substantially higher; 45% in direct costs (€16,237 vs. €11,184), 35% in home care costs (€3123 vs. €2320), 8% in social transfer income (€17,257 vs. €15,994) and they had 27% lower income (€10,136 vs. €13,845). The economic burden peaked at year of diagnosis, but the difference became increasingly pronounced in the years following the HF diagnosis. CONCLUSION: Patients with concomitant HF and DM had a significantly higher economic burden compared to patients with HF but without DM.

Self-assessed health status and associated mortality in endocarditis: secondary findings from the POET trial.

PURPOSE: Self-assessed poor health status is associated with increased risk of mortality in several cardiovascular conditions, but has not been investigated in patients with endocarditis. We examined health status and mortality in patients with endocarditis. METHODS: This is a re-specified substudy of the randomized POET endocarditis trial, which included 400 patients. Patients completed the single-question self-assessed health status from the Short-Form 36 questionnaire at time of randomization and were categorized as having poor or non-poor (excellent/very good, good, or fair) health status. Self-assessed health status and all-cause mortality were examined by a Cox regression model. RESULTS: Self-assessed health status was completed by 266 (67%) patients with a mean age of 68.0 years (± 11.8), 54 (20%) were females, and 86 (32%) had one or more major concurrent medical conditions besides endocarditis. The self-assessed health status distribution was poor (n = 21, 8%) and non-poor (n = 245, 92%). The median follow-up was 3.3 years and death occurred in 9 (43%) and 48 (20%) patients reporting poor and non-poor health status, respectively, and mortality rates [mortality/100 person-years, 95% confidence interval (CI)] were 18.1 (95% CI 9.4-34.8) and 5.4 (95% CI 4.1-7.2), i.e., the crude hazard ratio for death was 3.4 (95% CI: 1.7-7.0, p < 0.01). CONCLUSION: Self-assessed poor health status compared with non-poor health status as assessed by a single question was associated with a threefold increased long-term mortality in patients with endocarditis.

The impact of partial-oral endocarditis treatment on anxiety and depression in the POET trial.

BACKGROUND: The Partial-Oral versus Intravenous Antibiotic Treatment of Endocarditis Trial (POET) found that partial-oral outpatient treatment was non-inferior to conventional in-hospital intravenous treatment in patients with left-sided infective endocarditis. We examined the impact of treatment strategy on levels of anxiety and depression. METHODS: Patients completed the Hospital Anxiety and Depression Scale (HADS) at randomization, at antibiotic completion, and after month 3 and month 6. Changes in anxiety and depression (each subdimension 0-21, high scores indicating worse) were calculated using a repeated measure analysis of covariance model with primary assessment after 6 months. Change in score of 1.7 represented a minimal clinical important difference (MCID). RESULTS: Among the 400 patients enrolled in the POET trial, 263 (66%) completed HADS at randomization with reassessment rates of 86-87% at the three subsequent timepoints. Patients in the partial-oral group and the intravenous group had similar improvements after 6 months in levels of anxiety (-1.8 versus -1.6, P = 0.62) and depression (-2.1 versus -1.9, P = 0.63), although patients in the partial-oral group had numerically lower levels of anxiety and depression throughout. An improvement in MCID scores after 6 months was reported by 47% versus 45% (p = 0.80) patients for anxiety and by 51% versus 54% (p = 0.70) for depression. CONCLUSION: Patients with endocarditis receiving partial-oral outpatient treatment reported similar significant improvements in anxiety and depression at 6 months, as compared to conventionally treated, but numerically lower levels throughout. These findings support the usefulness of partial-oral treatment.

Cause-specific death and risk factors of 1-year mortality after implantable cardioverter-defibrillator implantation: a nationwide study.

AIMS: Current treatment guidelines recommend implantable cardioverter-defibrillators (ICDs) in eligible patients with an estimated survival beyond 1 year. There is still an unmet need to identify patients who are unlikely to benefit from an ICD. We determined cause-specific 1-year mortality after ICD implantation and identified associated risk factors. METHODS AND RESULTS: Using Danish nationwide registries (2000-2017), we identified 14 516 patients undergoing first-time ICD implantation for primary or secondary prevention. Risk factors associated with 1-year mortality were evaluated using multivariable logistic regression. The median age was 66 years, 81.3% were male, and 50.3% received an ICD for secondary prevention. The 1-year mortality rate was 4.8% (694/14 516). ICD recipients who died within 1 year were older and more comorbid compared to those who survived (72 vs. 66 years, P < 0.001). Risk factors associated with increased 1-year mortality included dialysis [odds ratio (OR): 3.26, confidence interval (CI): 2.37-4.49], chronic renal disease (OR: 2.14, CI: 1.66-2.76), cancer (OR: 1.51, CI: 1.15-1.99), age 70-79 years (OR: 1.65, CI: 1.36-2.01), and age ≥80 years (OR: 2.84, CI: 2.15-3.77). The 1-year mortality rates for the specific risk factors were: dialysis (13.8%), chronic renal disease (13.1%), cancer (8.5%), age 70-79 years (6.9%), and age ≥80 years (11.0%). Overall, the most common causes of mortality were related to cardiovascular diseases (62.5%), cancer (10.1%), and endocrine disorders (5.0%). However, the most common cause of death among patients with cancer was cancer-related (45.7%). CONCLUSION: Among ICD recipients, mortality rates were low and could be indicative of relevant patient selection. Important risk factors of increased 1-year mortality included dialysis, chronic renal disease, cancer, and advanced age.

Glycated haemoglobin levels among 3295 hospitalized COVID-19 patients, with and without diabetes, and risk of severe infection, admission to an intensive care unit and all-cause mortality.

AIM: To determine the risk of adverse outcomes across the spectrum of glycated haemoglobin (HbA1c) levels among hospitalized COVID-19 patients with and without diabetes. MATERIALS AND METHODS: Danish nationwide registries were used to study the association between HbA1c levels and 30-day risk of all-cause mortality and the composite of severe COVID-19 infection, intensive care unit (ICU) admission and all-cause mortality. The study population comprised patients hospitalized with COVID-19 (3 March 2020 to 31 December 2020) with a positive polymerase chain reaction (PCR) test and an available HbA1c ≤ 6 months before the first positive PCR test. All patients had at least 30 days of follow-up. Among patients with diabetes, HbA1c was categorized as <48 mmol/mol, 48 to 53 mmol/mol, 54 to 58 mmol/mol, 59 to 64 mmol/mol (reference) and >64 mmol/mol. Among patients without diabetes, HbA1c was stratified into <31 mmol/mol, 31 to 36 mmol/mol (reference), 37 to 41 mmol/mol and 42 to 47 mmol/mol. Thirty-day standardized absolute risks and standardized absolute risk differences are reported. RESULTS: We identified 3295 hospitalized COVID-19 patients with an available HbA1c (56.2% male, median age 73.9 years), of whom 35.8% had diabetes. The median HbA1c was 54 and 37 mmol/mol among patients with and without diabetes, respectively. Among patients with diabetes, the standardized absolute risk difference of the composite outcome was higher with HbA1c < 48 mmol/mol (12.0% [95% confidence interval {CI} 3.3% to 20.8%]) and HbA1c > 64 mmol/mol (15.1% [95% CI 6.2% to 24.0%]), compared with HbA1c 59 to 64 mmol/mol (reference). Among patients without diabetes, the standardized absolute risk difference of the composite outcome was greater with HbA1c < 31 mmol/mol (8.5% [95% CI 0.5% to 16.5%]) and HbA1c 42 to 47 mmol/mol (6.7% [95% CI 1.3% to 12.1%]), compared with HbA1c 31 to 36 mmol/mol (reference). CONCLUSIONS: Patients with COVID-19 and HbA1c < 48 mmol/mol or HbA1c > 64 mmol/mol had a higher associated risk of the composite outcome. Similarly, among patients without diabetes, varying HbA1c levels were associated with higher risk of the composite outcome.

Initiation of domiciliary care and nursing home admission following first hospitalization for heart failure, stroke, chronic obstructive pulmonary disease or cancer.

BACKGROUND: Patients with chronic diseases are at higher risk of requiring domiciliary and nursing home care, but how different chronic diseases compare in terms of risk is not known. We examined initiation of domiciliary care and nursing home admission among patients with heart failure (HF), stroke, COPD and cancer. METHODS: Patients with a first-time hospitalization for HF, stroke, COPD or cancer from 2008-2016 were identified. Patients were matched on age and sex and followed for five years. RESULTS: 111,144 patients, 27,786 with each disease, were identified. The median age was 69 years and two thirds of the patients were men. The 5-year risk of receiving domiciliary care was; HF 20.9%, stroke 25.2%, COPD 24.6% and cancer 19.3%. The corresponding adjusted hazard ratios (HRs), with HF patients used as reference, were: stroke 1.35[1.30-1.40]; COPD 1.29[1.25-1.34]; and cancer 1.19[1.14-1.23]. The five-year incidence of nursing home admission was 6.6% for stroke, and substantially lower in patients with HF(2.6%), COPD(2.6%) and cancer (1.5%). The adjusted HRs were (HF reference): stroke, 2.44 [2.23-2.68]; COPD 1.01 [0.91-1.13] and cancer 0.76 [0.67-0.86]. Living alone, older age, diabetes, chronic kidney disease, depression and dementia predicted a higher likelihood of both types of care. CONCLUSIONS: In patients with HF, stroke, COPD or cancer 5-year risk of domiciliary care and nursing home admission, ranged from 19-25% and 1-7%, respectively. Patients with stroke had the highest rate of domiciliary care and were more than twice as likely to be admitted to a nursing home, compared to patients with the other conditions.

Room for improvement: initiation of lipid-lowering treatment and achievement of lipid target levels-a Danish registry-based study.

AIMS: Prevention of adverse outcomes in individuals with high cholesterol levels may be improved by intensified lipid-lowering treatment (LLT). We studied whether treatment goals of low-density lipoprotein cholesterol (LDL-C) were reached within 1 year from baseline (defined as first LDL-C measurement) in a Danish population. METHODS AND RESULTS: Danish registries were used to identify all persons in the Northern Region of Denmark who had LDL-C measured between 1997 and 2012 and who were naïve to LLT. Patients were categorized in LDL-C <5 or ≥5 mmol/L and further subdivided into low, high, and very high predicted cardiovascular (CV) risk as suggested by European guidelines for risk stratification. Initiation of LLT and lipid target levels were assessed after 1 year (3.0, 2.5, and 1.8 mmol/L, respectively). In this study, we examined the intensity of LLT and whether treatment goals were reached. More patients with LDL-C ≥5 mmol/L, regardless of the CV risk, initiated LLT compared with patients who had a very high CV risk and LDL-C <5 mmol/L. In total, 37.7% (n = 32 581) of all patients with a follow-up LDL-C, and 25.1% (n = 3229) of patients with LDL-C ≥5 mmol/L, had achieved their target levels after 1 year. Only 45.2% (n = 4545) of the LDL-C ≥5 mmol/L high-risk patients with a follow-up LDL-C had started LLT 12 months after baseline. CONCLUSION: Less than half of patients presenting with an LDL-C ≥5 mmol/L start LLT within 1 year, representing a missed opportunity for both primary and secondary prevention of CV disease.

Self-reported health status and the associated risk of mortality in heart failure: The DANISH trial.

OBJECTIVE: To examine the gradual association between self-reported health status and mortality in patients with heart failure (HF) as current research has focused on poor health status and increased risk of mortality. METHOD: This is a substudy of the DANISH (Defibrillator Implantation in Patients with Nonischemic Systolic HF) trial in which 1116 patients were randomized to receive or not receive an implantable cardioverter-defibrillator. Health status was assessed by a single question of the Short-Form 36. Patients were classified as having excellent/very good, good, fair (reference) or poor health status. We assessed the association between health status and mortality using multivariable Cox proportional hazard models. RESULTS: Self-reported health status was completed by 943 (84%) patients at randomization with a median follow-up of 67 months and a health status distribution of; excellent/very good (n = 79, 8%), good (n = 369, 39%), fair (n = 409, 43%), and poor (n = 86, 9%). All-cause mortality (death events/ 100 person-years) occurred with gradual differences according to health status from excellent/ very good (2.14), good (3.74), fair (5.21) to poor health status (5.57). The gradual difference yielded a crude hazard ratio (HR) of 0.40, 95% CI 0.20-0.80 (adjusted HR 0.47 (95% CI 0.23-0.95) for excellent/ very good health status, HR 0.71, 95% CI 0.52-0.97 (adjusted HR 0.78 (95% CI 0.56-1.08) for good health status. Poor being worse than fair health status yielded a crude HR of 1.07, 95% CI 0.67-1.69. CONCLUSION: Excellent/very good self-reported health status as assessed by a single question was associated with lower long-term mortality in patients with HF.

Serum potassium in the PARADIGM-HF trial.

AIMS: The associations between potassium level and outcomes, the effect of sacubitril-valsartan on potassium level, and whether potassium level modified the effect of sacubitril-valsartan in patients with heart failure and a reduced ejection fraction were studied in PARADIGM-HF. Several outcomes, including cardiovascular death, sudden death, pump failure death, non-cardiovascular death and heart failure hospitalization, were examined. METHODS AND RESULTS: A total of 8399 patients were randomized to either enalapril or sacubitril-valsartan. Potassium level at randomization and follow-up was examined as a continuous and categorical variable (≤3.5, 3.6-4.0, 4.1-4.9, 5.0-5.4 and ≥5.5 mmol/L) in various statistical models. Hyperkalaemia was defined as K+ ≥5.5 mmol/L and hypokalaemia as K+ ≤3.5 mmol/L. Compared with potassium 4.1-4.9 mmol/L, both hypokalaemia [hazard ratio (HR) 2.40, 95% confidence interval (CI) 1.84-3.14] and hyperkalaemia (HR 1.42, 95% CI 1.10-1.83) were associated with a higher risk for cardiovascular death. However, potassium abnormalities were similarly associated with sudden death and pump failure death, as well as non-cardiovascular death and heart failure hospitalization. Sacubitril-valsartan had no effect on potassium overall. The benefit of sacubitril-valsartan over enalapril was consistent across the range of baseline potassium levels. CONCLUSIONS: Although both higher and lower potassium levels were independent predictors of cardiovascular death, potassium abnormalities may mainly be markers rather than mediators of risk for death.

Quality of life and the associated risk of all-cause mortality in nonischemic heart failure.

OBJECTIVES: To examine the association between health-related quality of life (HRQoL) and mortality in patients with heart failure (HF). BACKGROUND: The potential association of HRQoL and mortality in patients with HF is unclear. We investigated this association in The Danish Study to Assess the Efficacy of Implantable Cardioverter Defibrillators (ICD) in Patients with Non-ischemic Systolic Heart Failure on Mortality (DANISH). METHODS: In DANISH, a total of 1116 patients with non-ischemic systolic HF on guideline-recommended therapy were randomized to ICD therapy or usual clinical care. HRQoL was assessed at randomization using the disease-specific Minnesota Living with Heart Failure Questionnaire (MLHFQ, 0-105, high score indicating worse HRQoL). Multivariable Cox proportional hazard models were used to compare hazard ratios (HR) for all-cause mortality according to MLHFQ above or below 45, as recommended by a recent meta-analysis, to identify patients with poor HRQoL. RESULTS: HRQoL was completed by 935 (84%) patients at baseline with a median follow-up of 67 months (IQR 47-83). Patients with poor HRQoL (MLHFQ score > 45, median 60 (IQR 53-71),n = 350) had a higher incidence of all-cause mortality than patients with moderate/good HRQoL (MLHFQ ≤45, median 23 (IQR 13-33), n = 585), respectively 26% vs. 18% with an unadjusted HR of 1.57 (95% CI 1.19-2.08, p = .002), and an adjusted HR of 1.39 (95% CI 1.01-1.91, p = .04). CONCLUSION: Poor HRQoL was associated with an increased risk of all-cause mortality after adjustment for traditional risk factors.

Association between Type D personality and outcomes in patients with non-ischemic heart failure.

PURPOSE: The "distressed" (Type D) personality trait has been reported to be over-represented in patients with heart failure (HF) compared to the background population and may provide prognostic information for mortality. We examined the association between Type D personality and outcomes in the DANISH trial (The Danish Study to Assess the Efficacy of Implantable Cardioverter Defibrillators in Patients with Non-ischemic Systolic Heart Failure on Mortality). METHODS: The DANISH trial included a total of 1116 patients with non-ischemic HF on guideline-recommended therapy. Type D personality was assessed with the Type D Scale (DS14) at baseline and investigated through follow-up accordingly. Multivariable Cox proportional hazard models were used to compare hazard ratios (HR) of cardiovascular and all-cause mortality. RESULTS: Type D personality assessment was completed by 873 (78%) patients at baseline and Type D personality was found in 120 (14%) patients. The median follow-up was 67 months (interquartile range [IQR] 48-83). Among patients with versus without Type D personality, 22% versus 19% died from all-cause yielding similar incidence rates of 4.62 (95% CI 3.14-6.87) versus 3.95 (95% CI 3.37-4.66) per 100 person-years. The adjusted risk of all-cause mortality was not significantly different in patients with versus without Type D personality with an adjusted HR of 1.31 (95% CI 0.84-2.03, p = 0.23) with similar results for cardiovascular death (HR 1.46 (95% CI 0.88-2.44, p = 0.15). CONCLUSION: Type D personality was not significantly associated with increased risk of all-cause mortality or cardiovascular death in patients with non-ischemic HF.

The economic burden of heart failure in Denmark from 1998 to 2016.

BACKGROUND: Heart failure (HF) imposes a large burden on both the individual and the society. The aim of this study was to investigate the economic burden (either direct or indirect costs) attributed to patients with HF before, at, and after time of diagnosis. METHODS AND RESULTS: Using Danish nationwide registries we identified all patients > 18 years with a first-time diagnosis of HF from 1998-2016 and matched them 1:1 with a control group from the background population on age, gender, marital status, and educational level. The economic analysis of the total costs after diagnosis was based on direct costs including hospitalization, procedures, medication, and indirect costs including social welfare and lost productivity to estimate the annual cost of HF. A total of 176 067 HF patients with a median age of 76 (interquartile range 67-84) years and 55% male were included. Patients with HF incurred an average of €17 039 in total annual direct (€11 926) and indirect (€5113) healthcare costs peaking at year of diagnosis compared to €5936 in the control group with the majority attributable to inpatient admissions. The total annual net costs including public transfer after index HF were €11 957 higher in patients with HF compared to controls and the economic consequences were evident more than 2 years prior to the diagnosis of HF. CONCLUSION: Patients with HF impose significantly higher total annual healthcare costs compared to a matched control group with findings evident more than 2 years prior to HF diagnosis.

Heart failure and the prognostic impact and incidence of new-onset of diabetes mellitus: a nationwide cohort study.

BACKGROUND: Prevalent diabetes at the time of heart failure (HF) diagnosis is associated with a higher risk of death, but the incidence and prognostic importance of new-onset diabetes in patients with established HF remains unknown. METHODS: Patients with a first hospitalization for HF in the period 2003-2014 were included and stratified according to history of diabetes. Annual incidence rates of new-onset diabetes were calculated and time-dependent multivariable Cox regression models were used to compare the risk of death in patients with prevalent and new-onset diabetes with patients without diabetes as reference. The model was adjusted for age, sex, duration of HF, educational level and comorbidity. Covariates were continuously updated throughout follow-up. RESULTS: A total of 104,522 HF patients were included in the study, of which 21,216 (19%) patients had diabetes at baseline, and 8164 (10%) developed new-onset diabetes during a mean follow-up of 3.9 years. Patients with new-onset diabetes and prevalent diabetes were slightly younger than patients without diabetes (70 vs. 74 and 77, respectively), more likely to be men (62% vs. 60% and 54%), and had more comorbidities expect for ischemic heart disease, hypertension and chronic kidney disease which were more prevalent among patients with prevalent diabetes. Incidence rates of new-onset diabetes increased from around 2 per 100 person-years in the first years following HF hospitalization up to 3 per 100 person-years after 5 years of follow-up. A total of 61,424 (59%) patients died during the study period with event rates per 100 person-years of 21.5 for new-onset diabetes, 17.9 for prevalent diabetes and 13.9 for patients without diabetes. Compared to patients without diabetes, new-onset diabetes was associated with a higher risk of death (adjusted HR 1.47; 95% CI 1.42-1.52) and prevalent diabetes was associated with an intermediate risk (HR 1.19; 95% CI, 1.16-1.21). CONCLUSION: Following the first HF hospitalization, the incidence of new-onset diabetes was around 2% per year, rising to 3% after 5 years of follow-up. New-onset diabetes was associated with an increased risk of death, compared to HF patients with prevalent diabetes (intermediate risk) and HF patients without diabetes.

N-Terminal Pro-B-Type Natriuretic Peptide Levels for Risk Prediction in Patients With Heart Failure and Preserved Ejection Fraction According to Atrial Fibrillation Status.

Background NT-proBNP (N-terminal pro-B-type natriuretic peptide) is useful in diagnosis and prognostication in heart failure (HF). We examined the relationship between NT-proBNP and outcomes in patients with HF and preserved ejection fraction, with and without atrial fibrillation (AF). Methods and Results Among 3835 HF with preserved ejection fraction patients enrolled in the I-Preserve (Irbesartan in Heart Failure With Preserved Systolic Function trial) or TOPCAT trial (Treatment of Preserved Cardiac Function in Heart Failure With an Aldosterone Antagonist), 719 (19%) patients had AF on their baseline ECG. Median (Q1-Q3) levels of NT-proBNP were 1286 pg/mL (778-2072) in those with AF and 288 pg/mL (122-704) in those without ( P<0.001). We analyzed patients using 4 NT-proBNP bands: <400, 400 to 999 (reference), 1000 to 1999, and ≥2000 pg/mL. The event rates for the primary composite outcome of cardiovascular death or HF hospitalization were higher in patients with AF versus patients without or those without without AF in the lowest NT-proBNP band (<400 pg/mL; 8.0 versus 3.2 per 100 patient-years), whereas for the higher bands the opposite was true (1000-1999 pg/mL; 11.4 versus 13.2 per 100 patient-years and ≥2000 pg/mL; 17.4 versus 25.6 per 100 patient-years). In adjusted analyses, higher NT-proBNP levels were less predictive of HF hospitalization than mortality in patients with AF compared with those without. Conclusions Event rates in HF with preserved ejection fraction patients without AF and with NT-proBNP <400 pg/mL are low. Among patients with NT-proBNP ≥400 pg/mL, the relationship between NT-proBNP and outcomes differs with lower absolute risk in patients who have AF compared with those who do not have AF.

The impact of implantable cardioverter-defibrillator implantation on health-related quality of life in the DANISH trial.

AIM: The Danish Study to Assess the Efficacy of Implantable Cardioverter-Defibrillators (ICD) in Patients with Non-ischaemic Systolic Heart Failure (HF) on Mortality (DANISH) found no overall effect on all-cause mortality. The effect of ICD implantation on health-related quality of life (HRQoL) remains to be established as previous trials have demonstrated conflicting results. We investigated the impact of ICD implantation on HRQoL in patients with non-ischaemic systolic HF, a prespecified secondary endpoint in DANISH. METHODS AND RESULTS: In DANISH, a total of 1116 patients with non-ischaemic systolic HF were randomly assigned (1:1) to ICD implantation or usual clinical care (control). Patients completed disease-specific HRQoL as assessed by Minnesota Living with Heart Failure Questionnaire (MLHFQ; 0-105, high indicating worse). Changes in HRQoL 8 months after randomization were assessed with a mixed-effects model. At randomization, MLHFQ was completed by 935 (84%) patients (n = 472 in the ICD group and n = 463 in the control group) and was reassessed in 274 (58%) and 292 (63%) patients, respectively after 8 months for the primary analysis. Patients in the ICD group vs. the control group had similar improvements in MLHFQ after 8 months [least square mean -7.0 vs. -4.2 (P = 0.13)]. A clinically relevant improvement (decrease ≥5) in the MLHFQ overall score at 8 months was observed in 151 patients in the ICD group and 148 patients in the control group [55% vs. 51%, respectively (P = 0.25)]. CONCLUSION: Implantable cardioverter-defibrillator implantation in patients with non-ischaemic systolic HF did not significantly alter HRQoL compared with patients randomized to usual clinical care.

Cardiac ventricular sizes are reduced in patients with long-term, normoalbuminuric type 1 diabetes compared to the non-diabetic background population.

AIMS: Type 1 diabetes entails increased cardiovascular morbidity and cardiac chamber sizes are associated with cardiovascular disease. The aim of this study was to compare cardiac chamber sizes in normoalbuminuric persons with type 1 diabetes to a background population without diabetes. METHODS: In a cross-sectional study, we examined 71 normoalbuminuric persons with long-term type 1 diabetes without known cardiovascular disease using cardiac multi-detector computed tomography. Cardiac chamber sizes and left ventricular remodelling were compared to persons without diabetes from the Copenhagen General Population Study. RESULTS: Participants were median (interquartile range) 54 (48-60) (type 1 diabetes) and 57 (50-64) (without diabetes) years old and 59% were men (both groups). Participants with type 1 diabetes had smaller left ventricular mass (-3.5 g/m2, 95% confidence interval -5.8 to -1.3) and left (-4.0 mL/m2, 95% confidence interval -6.9 to -1.0) and right (-11.7 mL/m2, 95% confidence interval -15.4 to -7.9) ventricular volumes in multivariable analyses (adjusted for age, sex, body composition, blood pressure and antihypertensive medication), but no differences in atrial volumes. CONCLUSION: Persons with long-term type 1 diabetes had smaller left ventricular mass and biventricular volumes, yet similar atrial sizes, compared to a background population without diabetes. These findings may reflect subclinical development of diabetic cardiomyopathy.

Differential Impact of Heart Failure With Reduced Ejection Fraction on Men and Women.

BACKGROUND: Heart failure (HF) trials initiated in the last century highlighted many differences between men and women. Of particular concern was undertreatment of women compared with men, but much has changed during the past 20 years. OBJECTIVES: This study sought to identify these changes, which may give a new perspective on the management of, and outcomes in, women with HF. METHODS: The study analyzed 12,058 men and 3,357 women enrolled in 2 large HF with reduced ejection fraction (HFrEF) trials with near identical inclusion and exclusion criteria and the same principal outcomes. Outcomes were adjusted for other prognostic variables including N-terminal pro-B-type natriuretic peptide. RESULTS: Women were older and more often obese than men were, had slightly higher systolic blood pressure and heart rate, and were less likely to have most comorbidities, except hypertension. Women had more symptoms and signs (e.g., pedal edema 23.4% vs 19.9%; p < 0.0001) and worse quality of life-median Kansas City Cardiomyopathy Questionnaire Clinical Summary Score 71.3 (interquartile range: 53.4 to 86.5) versus 81.3 (interquartile range: 65.1 to 92.7; p < 0.0001)-despite similar left ventricular ejection fraction and N-terminal pro-B-type natriuretic peptide. However, women had lower mortality (adjusted hazard ratio: 0.68; 95% confidence interval: 0.62 to 0.74; p < 0.001) and risk of HF hospitalization (hazard ratio: 0.80; 95% confidence interval: 0.72 to 0.89; p < 0.001). Diuretics and anticoagulants were underutilized in women. Device therapy was underused in both men and women, but more so in women (e.g., defibrillator 8.6% vs. 16.6%; p < 0.0001). CONCLUSIONS: Although women with HFrEF live longer than men, their additional years of life are of poorer quality, with greater self-reported psychological and physical disability. The explanation for this different sex-related experience of HFrEF is unknown as is whether physicians recognize it. Women continue to receive suboptimal treatment, compared with men, with no obvious explanation for this shortfall.

Duration and complications of diabetes mellitus and the associated risk of infective endocarditis.

BACKGROUND: Long duration of diabetes mellitus (DM) is associated with an increased risk of infection, however no studies have yet focused on the duration of DM and the associated risk of infective endocarditis (IE). METHODS: Patients with DM were identified through the Danish Prescription Registry, 1996-2015. Duration of DM was split in follow-up periods of: 0-5 years, 5-10 years, 10-15 years, and >15 years. Multivariable adjusted Poisson regression was used to calculate incidence rate ratios (IRR) according to study groups. DM late-stage complications and the associated risk of IE were investigated as time-varying covariates using the validated Diabetes Complications Severity Index (DCSI). RESULTS: We included 299,551 patients with DM. In patients with DM duration of 0-5 years, 5-10 years, 10-15 years, and >15 years, the incidence rates of IE were 0.24, 0.33, 0.58, and 0.96 cases of IE/1000 person years, respectively. Patients with DM duration 5-10 years, 10-15 years, and >15 years were associated with a higher risk of IE with an IRR of 1.24 (95% CI: 1.02-1.51), 1.92 (95% CI: 1.52-2.43) and 3.05 (95% CI: 2.11-4.40), respectively, compared with DM duration 0-5 years. Patients with a DCSI score of 2, 3 and >3 were associated with a higher risk of IE compared with patients with a DCSI score of 0, IRR = 1.78 (95% CI: 1.34-2.36), IRR = 2.34 (95% CI: 1.73-3.16), and IRR = 2.59 (95% CI: 1.92-3.48), respectively. CONCLUSION: This study shows a stepwise increase in the risk of IE with DM duration and severity independent of age and known comorbidity.

Heart failure with reduced ejection fraction: comparison of patient characteristics and clinical outcomes within Asia and between Asia, Europe and the Americas.

AIMS: Nearly 60% of the world's population lives in Asia but little is known about the characteristics and outcomes of Asian patients with heart failure with reduced ejection fraction (HFrEF) compared to other areas of the world. METHODS AND RESULTS: We pooled two, large, global trials, with similar design, in 13 174 patients with HFrEF (patient distribution: China 833, India 1390, Japan 209, Korea 223, Philippines 223, Taiwan 199 and Thailand 95, Western Europe 3521, Eastern Europe 4758, North America 613, and Latin America 1110). Asian patients were younger (55.0-63.9 years) than in Western Europe (67.9 years) and North America (66.6 years). Diuretics and devices were used less, and digoxin used more, in Asia. Mineralocorticoid receptor antagonist use was higher in China (66.3%), the Philippines (64.1%) and Latin America (62.8%) compared to Europe and North America (range 32.8% to 49.6%). The rate of cardiovascular death/heart failure hospitalization was higher in Asia (e.g. Taiwan 17.2, China 14.9 per 100 patient-years) than in Western Europe (10.4) and North America (12.8). However, the adjusted risk of cardiovascular death was higher in many Asian countries than in Western Europe (except Japan) and the risk of heart failure hospitalization was lower in India and in the Philippines than in Western Europe, but significantly higher in China, Japan, and Taiwan. CONCLUSION: Patient characteristics and outcomes vary between Asia and other regions and between Asian countries. These variations may reflect several factors, including geography, climate and environment, diet and lifestyle, health care systems, genetics and socioeconomic influences.
