Glycaemic control and insulin therapy are significant confounders of the obesity paradox in patients with heart failure and diabetes mellitus. Clin Res Cardiol 2024; 113:822-830. [PMID: 37608126 PMCID: PMC11108876 DOI: 10.1007/s00392-023-02268-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Accepted: 09/13/2022] [Indexed: 08/24/2023]
Abstract
BACKGROUND A high body mass index (BMI) confers a paradoxical survival benefit in patients with heart failure (HF) or diabetes mellitus (DM). There is, however, controversy whether an obesity paradox is also present in patients with HF and concomitant DM. In addition, the influence of glycaemic control and diabetes treatment on the presence or absence of the obesity paradox in patients with HF and DM is unknown. METHODS We identified 2936 patients with HF with reduced ejection fraction (HFrEF) in the HF registries of the universities of Heidelberg, Germany, and Hull, UK (general sample). Of these, 598 (20%) were treated for concomitant DM (DM subgroup). The relationship between BMI and all-cause mortality was analysed in both the general sample and the DM subgroup. Patients with concomitant DM were stratified according to HbA1c levels or type of diabetes treatment and analyses were repeated. RESULTS We found an inverse BMI-mortality relationship in both the general sample and the DM subgroup. However, the obesity paradox was less pronounced in patients with diabetes treated with insulin and it disappeared in those with poor glycaemic control as defined by HbA1c levels > 7.5%. CONCLUSION In patients with HFrEF, a higher BMI is associated with better survival irrespective of concomitant DM. However, insulin treatment and poor glycaemic control make the relationship much weaker.

Outcomes in patients treated with loop diuretics without a diagnosis of heart failure: a retrospective cohort study. Heart 2024; 110:854-862. [PMID: 38631899 DOI: 10.1136/heartjnl-2023-323577] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Accepted: 03/15/2024] [Indexed: 04/19/2024] Open
Abstract
BACKGROUND Loop diuretics are commonly prescribed in the community, not always to patients with a recorded diagnosis of heart failure (HF). The rate of HF events in patients prescribed loop diuretics without a diagnosis of HF is unknown. METHODS This was a propensity-matched cohort study using data from the Clinical Practice Research Datalink, Hospital Episode Statistics and Office of National Statistics in the UK. Patients prescribed a loop diuretic without a diagnosis of HF (loop diuretic group) between 1 January 2010 and 31 December 2015 were compared with patients with HF (HF group)-analysis A, and patients with risk factors for HF (either ischaemic heart disease, or diabetes and hypertension-at-risk group)-analysis B. The primary endpoint was an HF event (a composite of presentation with HF symptoms, HF hospitalisation, HF diagnosis (analysis B only) and all-cause mortality). RESULTS From a total population of 180 384 patients (78 968 in the loop diuretic group, 28 177 in the HF group and 73 239 in the at-risk group), there were 59 694 patients, 22 352 patients and 57 219 patients in the loop diuretic, HF and at-risk groups, respectively, after exclusion criteria were applied. After propensity matching for age, sex and comorbidities, patients in the loop diuretic group had a similar rate of HF events as those in the HF group (71.9% vs 72.1%; HR=0.92 (95% CI 0.90 to 0.94); p<0.001), and twice as those in the at-risk group (59.2% vs 35.7%; HR=2.04 (95% CI 2.00 to 2.08); p<0.001). CONCLUSIONS Patients prescribed a loop diuretic without a recorded diagnosis of HF experience HF events at a rate comparable with that of patients with a recorded diagnosis of HF; many of these patients may have undiagnosed HF.

Urinary proteomic signature of mineralocorticoid receptor antagonism by spironolactone: evidence from the HOMAGE trial. Heart 2024:heartjnl-2023-323796. [PMID: 38729636 DOI: 10.1136/heartjnl-2023-323796] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Accepted: 04/28/2024] [Indexed: 05/12/2024] Open
Abstract
OBJECTIVE Heart failure (HF) is characterised by collagen deposition. Urinary proteomic profiling (UPP) followed by peptide sequencing identifies parental proteins, for over 70% derived from collagens. This study aimed to refine understanding of the antifibrotic action of spironolactone. METHODS In this substudy (n=290) to the Heart 'Omics' in Ageing Study trial, patients were randomised to usual therapy combined or not with spironolactone 25-50 mg/day and followed for 9 months. The analysis included 1498 sequenced urinary peptides detectable in ≥30% of patients and carboxyterminal propeptide of procollagen I (PICP) and PICP/carboxyterminal telopeptide of collagen I (CITP) as serum biomarkers of COL1A1 synthesis. After rank normalisation of biomarker distributions, between-group differences in their changes were assessed by multivariable-adjusted mixed model analysis of variance. Correlations between the changes in urinary peptides and in serum PICP and PICP/CITP were compared between groups using Fisher's Z transform. RESULTS Multivariable-adjusted between-group differences in the urinary peptides with error 1 rate correction were limited to 27 collagen fragments, of which 16 were upregulated (7 COL1A1 fragments) on spironolactone and 11 downregulated (4 COL1A1 fragments). Over 9 months of follow-up, spironolactone decreased serum PICP from 81 (IQR 66-95) to 75 (61-90) µg/L and PICP/CITP from 22 (17-28) to 18 (13-26), whereas no changes occurred in the control group, resulting in a difference (spironolactone minus control) expressed in standardised units of -0.321 (95% CI 0.0007). Spironolactone did not affect the correlations between changes in urinary COL1A1 fragments and in PICP or the PICP/CITP ratio. CONCLUSIONS Spironolactone decreased serum markers of collagen synthesis and predominantly downregulated urinary collagen-derived peptides, but upregulated others. The interpretation of these opposite UPP trends might be due to shrinking the body-wide pool of collagens, explaining downregulation, while some degree of collagen synthesis must be maintained to sustain vital organ functions, explaining upregulation. Combining urinary and serum fibrosis markers opens new avenues for the understanding of the action of antifibrotic drugs. TRIAL REGISTRATION NUMBER NCT02556450.

Intravenous iron for heart failure, iron deficiency definitions, and clinical response: the IRONMAN trial. Eur Heart J 2024; 45:1410-1426. [PMID: 38446126 PMCID: PMC11032711 DOI: 10.1093/eurheartj/ehae086] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Revised: 11/26/2023] [Accepted: 01/30/2024] [Indexed: 03/07/2024] Open
Abstract
BACKGROUND AND AIMS What is the relationship between blood tests for iron deficiency, including anaemia, and the response to intravenous iron in patients with heart failure? METHODS In the IRONMAN trial, 1137 patients with heart failure, ejection fraction ≤ 45%, and either serum ferritin < 100 µg/L or transferrin saturation (TSAT) < 20% were randomized to intravenous ferric derisomaltose (FDI) or usual care. Relationships were investigated between baseline anaemia severity, ferritin and TSAT, to changes in haemoglobin from baseline to 4 months, Minnesota Living with Heart Failure (MLwHF) score and 6-minute walk distance achieved at 4 months, and clinical events, including heart failure hospitalization (recurrent) or cardiovascular death. RESULTS The rise in haemoglobin after administering FDI, adjusted for usual care, was greater for lower baseline TSAT (Pinteraction < .0001) and ferritin (Pinteraction = .028) and more severe anaemia (Pinteraction = .014). MLwHF scores at 4 months were somewhat lower (better) with FDI for more anaemic patients (overall Pinteraction = .14; physical Pinteraction = .085; emotional Pinteraction = .043) but were not related to baseline TSAT or ferritin. Blood tests did not predict difference in achieved walking distance for those randomized to FDI compared to control. The absence of anaemia or a TSAT ≥ 20% was associated with lower event rates and little evidence of benefit from FDI. More severe anaemia or TSAT < 20%, especially when ferritin was ≥100 µg/L, was associated with higher event rates and greater absolute reductions in events with FDI, albeit not statistically significant. CONCLUSIONS This hypothesis-generating analysis suggests that anaemia or TSAT < 20% with ferritin > 100 µg/L might identify patients with heart failure who obtain greater benefit from intravenous iron. This interpretation requires confirmation.

Medicines optimization prior to discharge in patients admitted to hospital with heart failure. ESC Heart Fail 2024; 11:950-961. [PMID: 38229241 DOI: 10.1002/ehf2.14638] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Revised: 10/25/2023] [Accepted: 11/28/2023] [Indexed: 01/18/2024] Open
Abstract
AIMS Approximately half of patients with heart failure and a reduced ejection fraction (HeFREF) are discharged from hospital on triple therapy [angiotensin-converting enzyme inhibitors (ACE-Is) or angiotensin receptor blockers (ARBs), beta-blockers (BBs), and mineralocorticoid receptor antagonists (MRAs)]. We investigated what proportion of patients are on optimal doses prior to discharge and how many might be eligible for initiation of sacubitril-valsartan or sodium-glucose co-transporter-2 inhibitors (SGLT2Is). METHODS AND RESULTS Between 2012 and 2017, 1277 patients admitted with suspected heart failure were enrolled at a single hospital serving a local community around Kingston upon Hull, UK. Eligibility for sacubitril-valsartan or SGLT2I was based on entry criteria for the PIONEER-HF, DAPA-HF, and EMPEROR-Reduced trials. Four hundred fifty-five patients had HeFREF with complete data on renal function, heart rate, and systolic blood pressure (SBP) prior to discharge. Eighty-three per cent of patients were taking an ACE-I or ARB, 85% a BB, and 63% an MRA at discharge. More than 60% of patients were eligible for sacubitril-valsartan and >70% for SGLT2I. Among those not already receiving a prescription, 37%, 28%, and 49% were eligible to start ACE-I or ARB, BB, and MRA, respectively. Low SBP (≤105 mmHg) was the most frequent explanation for failure to initiate or up-titrate therapy. CONCLUSIONS Most patients admitted for heart failure are eligible for initiation of life-prolonging medications prior to discharge. A hospital admission may be a common missed opportunity to improve treatment for patients with HeFREF.

Abstract
PURPOSE OF REVIEW Fluid retention or congestion is a major cause of symptoms, poor quality of life, and adverse outcome in patients with heart failure (HF). Despite advances in disease-modifying therapy, the mainstay of treatment for congestion-loop diuretics-has remained largely unchanged for 50 years. In these two articles (part I: loop diuretics and part II: combination therapy), we will review the history of diuretic treatment and the current trial evidence for different diuretic strategies and explore potential future directions of research. RECENT FINDINGS We will assess recent trials including DOSE, TRANSFORM, ADVOR, CLOROTIC, OSPREY-AHF, and PUSH-AHF amongst others, and assess how these may influence current practice and future research. There are few data on which to base diuretic therapy in clinical practice. The most robust evidence is for high dose loop diuretic treatment over low-dose treatment for patients admitted to hospital with HF, yet this is not reflected in guidelines. There is an urgent need for more and better research on different diuretic strategies in patients with HF.

Proteomic profiles of left atrial volume and its influence on response to spironolactone: Findings from the HOMAGE trial and STANISLAS cohort. Eur J Heart Fail 2024. [PMID: 38528728 DOI: 10.1002/ejhf.3202] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 02/21/2024] [Accepted: 03/07/2024] [Indexed: 03/27/2024] Open
Abstract
AIMS High left ventricular filling pressure increases left atrial volume and causes myocardial fibrosis, which may decrease with spironolactone. We studied clinical and proteomic characteristics associated with left atrial volume indexed by body surface area (LAVi), and whether LAVi influences the response to spironolactone on biomarker expression and clinical variables. METHODS AND RESULTS In the HOMAGE trial, where people at risk of heart failure were randomized to spironolactone or control, we analysed 421 participants with available LAVi and 276 proteomic measurements (Olink) at baseline, month 1 and 9 (mean age 73 ± 6 years; women 26%; LAVi 32 ± 9 ml/m2). Circulating proteins associated with LAVi were also assessed in asymptomatic individuals from a population-based cohort (STANISLAS; n = 1640; mean age 49 ± 14 years; women 51%; LAVi 23 ± 7 ml/m2). In both studies, greater LAVi was significantly associated with greater left ventricular masses and volumes. In HOMAGE, after adjustment and correction for multiple testing, greater LAVi was associated with higher concentrations of matrix metallopeptidase-2 (MMP-2), insulin-like growth factor binding protein-2 (IGFBP-2) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) (false discovery rates [FDR] <0.05). These associations were externally replicated in STANISLAS (all FDR <0.05). Among these biomarkers, spironolactone decreased concentrations of MMP-2 and NT-proBNP, regardless of baseline LAVi (pinteraction > 0.10). Spironolactone also significantly reduced LAVi, improved left ventricular ejection fraction, lowered E/e', blood pressure and serum procollagen type I C-terminal propeptide (PICP) concentration, a collagen synthesis marker, regardless of baseline LAVi (pinteraction > 0.10). CONCLUSION In individuals without heart failure, LAVi was associated with MMP-2, IGFBP-2 and NT-proBNP. Spironolactone reduced these biomarker concentrations as well as LAVi and PICP, irrespective of left atrial size.

Hospital admissions in the last year of life of patients with heart failure. EUROPEAN HEART JOURNAL. QUALITY OF CARE & CLINICAL OUTCOMES 2024; 10:168-175. [PMID: 37553153 DOI: 10.1093/ehjqcco/qcad047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 06/05/2023] [Accepted: 08/07/2023] [Indexed: 08/10/2023]
Abstract
AIM To explore the frequency, causes, and pattern of hospitalisation for patients with chronic heart failure (HF) in the 12 months preceding death. We also investigated cause of death. METHODS Patients referred to a secondary care HF clinic were routinely consented for follow-up between 2001 and 2020 and classified into three phenotypes: (i) HF with reduced ejection fraction (HFrEF), (ii) HF with preserved ejection fraction (HFpEF) with plasma N-terminal pro B-type natriuretic peptide (NT-proBNP) 125-399 ng L-1, and (iii) HFpEF with NT-proBNP ≥400 ng L-1. Hospital admissions in the last year of life were classified as: HF, other cardiovascular (CV), or non-cardiovascular (non-CV). The cause of death was systematically adjudicated. RESULTS A total of 4925 patients (38% women; median age at death 81 [75-87] years) had 9127 hospitalisations in the last year of life. The median number of hospitalisations was 2 (1-3) and total days spent in hospital was 12 (2-25). Out of the total, 83% of patients had ≥1 hospitalisation but only 20% had ≥1 HF hospitalisation; 24% had ≥1 CV hospitalisation; 70% had ≥1 non-CV hospitalisation. Heart failure hospitalisations were most common in patients with HFrEF, but in all groups, at least two thirds of admissions were for non-CV causes. There were 788 (16%) deaths due to progressive HF, of which 74% occurred in hospital. CONCLUSION For patients with chronic HF in the last year of life, most hospitalisations were for non-CV causes regardless of HF phenotype. Most patients had no HF hospitalisations in their last year of life. Most deaths were from causes other than progressive HF.

Abstract
AIMS We aim to characterize the clinical and proteomic profiles of patients at risk of developing heart failure (HF), with and without coronary artery disease (CAD) or prior myocardial infarction (MI). METHODS AND RESULTS HOMAGE evaluated the effect of spironolactone on plasma and serum markers of fibrosis over 9 months of follow-up in participants with (or at risk of having) CAD, and raised natriuretic peptides. In this post hoc analysis, patients were classified as (i) neither CAD nor MI; (ii) CAD; or (iii) MI. Proteomic between-group differences were evaluated through logistic regression and narrowed using backward stepwise selection and bootstrapping. Among the 527 participants, 28% had neither CAD or MI, 31% had CAD, and 41% had prior MI. Compared with people with neither CAD nor MI, those with CAD had higher baseline plasma concentrations of matrix metalloproteinase-7 (MMP-7), galectin-4 (GAL4), plasminogen activator inhibitor 1 (PAI-1), and lower plasma peptidoglycan recognition protein 1 (PGLYRP1), whilst those with a history of MI had higher plasma MMP-7, neurotrophin-3 (NT3), pulmonary surfactant-associated protein D (PSPD), and lower plasma tumour necrosis factor-related activation-induced cytokine (TRANCE). Proteomic signatures were similar for patients with CAD or prior MI. Treatment with spironolactone was associated with an increase of MMP7, NT3, and PGLYRP1 at 9 months. CONCLUSIONS In patients at risk of developing HF, those with CAD or MI had a different proteomic profile regarding inflammatory, immunological, and collagen catabolic processes.

A novel, small-volume subcutaneous furosemide formulation delivered by an abdominal patch infusor device in patients with heart failure: results of two phase I studies. EUROPEAN HEART JOURNAL. CARDIOVASCULAR PHARMACOTHERAPY 2024; 10:35-44. [PMID: 37804170 PMCID: PMC10766906 DOI: 10.1093/ehjcvp/pvad073] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/22/2023] [Revised: 09/01/2023] [Accepted: 10/04/2023] [Indexed: 10/09/2023]
Abstract
AIMS Subcutaneous (SC) furosemide has potential advantages over intravenous (IV) furosemide by enabling self-administration or administration by a lay caregiver, such as facilitating early discharge, preventing hospitalizations, and in palliative care. A high-concentration, pH-neutral furosemide formulation has been developed for SC administration via a small patch infusor pump. We aimed to compare the bioavailability, pharmacokinetic (PK), and pharmacodynamic (PD) profiles of a new SC furosemide formulation with conventional IV furosemide and describe the first use of a bespoke mini-pump to administer this formulation. METHODS AND RESULTS A novel pH-neutral formulation of SC furosemide containing 80 mg furosemide in ∼2.7 mL (infused over 5 h) was investigated. The first study was a PK/PD study of SC furosemide compared with 80 mg IV furosemide administered as a bolus in ambulatory patients with heart failure (HF). The primary outcome was absolute bioavailability of SC compared with IV furosemide. The second study investigated the same SC furosemide preparation delivered by a patch infusor in patients hospitalized with HF. Primary outcome measures were treatment-emergent adverse events, infusion site pain, device performance, and PK measurements.The absolute bioavailability of SC furosemide in comparison to IV furosemide was 112%, resulting in equivalent diuresis and natriuresis. When SC furosemide was administered via the patch pump, there were no treatment-emergent adverse events and 95% of participants reported no/minor discomfort at the infusion site. CONCLUSION The novel preparation of SC furosemide had similar bioavailability to IV furosemide. Administration via a patch pump was feasible and well tolerated.

Which frailty tool best predicts morbidity and mortality in ambulatory patients with heart failure? A prospective study. EUROPEAN HEART JOURNAL. QUALITY OF CARE & CLINICAL OUTCOMES 2023; 9:731-739.

Abstract
BACKGROUND Frailty is common in patients with heart failure (HF) and is associated with adverse outcome, but it is uncertain how frailty should best be measured. OBJECTIVES To compare the prognostic value of commonly-used frailty tools in ambulatory patients with HF. METHODS AND RESULTS We assessed, simultaneously, three screening tools [clinical frailty scale (CFS); Derby frailty index (DFI); acute frailty network (AFN) frailty criteria), three assessment tools (Fried criteria; Edmonton frailty score (EFS); deficit index (DI)) and three physical tests (handgrip strength, timed get-up-and-go test (TUGT), 5-metre walk test (5MWT)] in consecutive patients with HF attending a routine follow-up visit. 467 patients (67% male, median age = 76 years, median NT-proBNP = 1156 ng/L) were enrolled. During a median follow-up of 554 days, 82 (18%) patients died and 201 (43%) patients were either hospitalised or died. In models corrected for age, Charlson score, haemoglobin, renal function, sodium, NYHA, atrial fibrillation (AF), and body mass index, only log[NT-proBNP] and frailty were independently associated with all-cause death. A base model for predicting mortality at 1 year including NYHA, log[NT-proBNP], sodium and AF, had a C-statistic = 0.75. Amongst screening tools: CFS (C-statistic = 0.84); amongst assessment tools: DI (C-statistic = 0.83) and amongst physical test: 5MWT (C-statistic = 0.80), increased model performance most compared with base model (P <0.05 for all). CONCLUSION Frailty is strongly associated with adverse outcomes in ambulatory patients with HF. When added to a base model for predicting mortality at 1 year including NYHA, NT-proBNP, sodium, and AF, CFS provides comparable prognostic information with assessment tools taking longer to perform.

Influence of serum transferrin concentration on diagnostic criteria for iron deficiency in chronic heart failure. ESC Heart Fail 2023; 10:2826-2836. [PMID: 37400990 PMCID: PMC10567655 DOI: 10.1002/ehf2.14438] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Revised: 03/23/2023] [Accepted: 05/29/2023] [Indexed: 07/05/2023] Open
Abstract
AIMS Transferrin saturation (TSAT), a marker of iron deficiency, reflects both serum concentrations of iron (SIC) and transferrin (STC). TSAT is susceptible to changes in each of these biomarkers. Little is known about determinants of STC and its influence on TSAT and mortality in patients with heart failure. Accordingly, we studied the relationship of STC to clinical characteristics, to markers of iron deficiency and inflammation and to mortality in chronic heart failure (CHF). METHODS AND RESULTS Prospective cohort of patients with CHF attending a clinic serving a large local population. A total of 4422 patients were included (median age 75 (68-82) years; 40% women; 32% with left ventricular ejection fraction ≤40%). STC ≤ 2.3 g/L (lowest quartile) was associated with older age, lower SIC and haemoglobin and higher high-sensitivity C-reactive protein, ferritin and N-terminal pro-brain natriuretic peptide compared with those with STC > 2.3 g/L. In the lowest STC quartile, 624 (52%) patients had SIC ≤13 μmol/L, of whom 38% had TSAT ≥20%. For patients in the highest STC quartile, TSAT was <20% when SIC was >13 μmol/L in 185 (17%) patients. STC correlated inversely with ferritin (r = -0.52) and high-sensitivity C-reactive protein (r = -0.17) and directly with albumin (r = 0.29); all P < 0.001. In models adjusted for age, N-terminal pro-brain natriuretic peptide and haemoglobin, both higher SIC (hazard ratio 0.87 [95% CI: 0.81-0.95]) and STC (hazard ratio 0.82 [95% CI: 0.73-0.91]) were associated with lower mortality. SIC was more strongly associated with both anaemia and mortality than either STC or TSAT. CONCLUSIONS Many patients with CHF and a low STC have low SIC even when TSAT is >20% and serum ferritin >100 μg/L; such patients have a high prevalence of anaemia and a poor prognosis and might have iron deficiency but are currently excluded from clinical trials of iron repletion.

Abstract
(1) Background: Kidney and cardiovascular diseases are responsible for a large fraction of population morbidity and mortality. Early, targeted, personalized intervention represents the ideal approach to cope with this challenge. Proteomic/peptidomic changes are largely responsible for the onset and progression of these diseases and should hold information about the optimal means of treatment and prevention. (2) Methods: We investigated the prediction of renal or cardiovascular events using previously defined urinary peptidomic classifiers CKD273, HF2, and CAD160 in a cohort of 5585 subjects, in a retrospective study. (3) Results: We have demonstrated a highly significant prediction of events, with an HR of 2.59, 1.71, and 4.12 for HF, CAD, and CKD, respectively. We applied in silico treatment, implementing on each patient's urinary profile changes to the classifiers corresponding to exactly defined peptide abundance changes, following commonly used interventions (MRA, SGLT2i, DPP4i, ARB, GLP1RA, olive oil, and exercise), as defined in previous studies. Applying the proteomic classifiers after the in silico treatment indicated the individual benefits of specific interventions on a personalized level. (4) Conclusions: The in silico evaluation may provide information on the future impact of specific drugs and interventions on endpoints, opening the door to a precision-based medicine approach. An investigation into the extent of the benefit of this approach in a prospective clinical trial is warranted.

Dapagliflozin vs. metolazone in heart failure resistant to loop diuretics. Eur Heart J 2023; 44:2966-2977. [PMID: 37210742 PMCID: PMC10424881 DOI: 10.1093/eurheartj/ehad341] [Citation(s) in RCA: 14] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 05/11/2023] [Accepted: 05/16/2023] [Indexed: 05/23/2023] Open
Abstract
BACKGROUND AND AIMS To examine the decongestive effect of the sodium-glucose cotransporter 2 inhibitor dapagliflozin compared to the thiazide-like diuretic metolazone in patients hospitalized for heart failure and resistant to treatment with intravenous furosemide. METHODS AND RESULTS A multi-centre, open-label, randomized, and active-comparator trial. Patients were randomized to dapagliflozin 10 mg once daily or metolazone 5-10 mg once daily for a 3-day treatment period, with follow-up for primary and secondary endpoints until day 5 (96 h). The primary endpoint was a diuretic effect, assessed by change in weight (kg). Secondary endpoints included a change in pulmonary congestion (lung ultrasound), loop diuretic efficiency (weight change per 40 mg of furosemide), and a volume assessment score. 61 patients were randomized. The mean (±standard deviation) cumulative dose of furosemide at 96 h was 977 (±492) mg in the dapagliflozin group and 704 (±428) mg in patients assigned to metolazone. The mean (±standard deviation) decrease in weight at 96 h was 3.0 (2.5) kg with dapagliflozin compared to 3.6 (2.0) kg with metolazone [mean difference 0.65, 95% confidence interval (CI) -0.12,1.41 kg; P = 0.11]. Loop diuretic efficiency was less with dapagliflozin than with metolazone [mean 0.15 (0.12) vs. 0.25 (0.19); difference -0.08, 95% CI -0.17,0.01 kg; P = 0.10]. Changes in pulmonary congestion and volume assessment score were similar between treatments. Decreases in plasma sodium and potassium and increases in urea and creatinine were smaller with dapagliflozin than with metolazone. Serious adverse events were similar between treatments. CONCLUSION In patients with heart failure and loop diuretic resistance, dapagliflozin was not more effective at relieving congestion than metolazone. Patients assigned to dapagliflozin received a larger cumulative dose of furosemide but experienced less biochemical upset than those assigned to metolazone.

Inferior vena cava diameter is associated with prognosis in patients with chronic heart failure independent of tricuspid regurgitation velocity. Clin Res Cardiol 2023; 112:1077-1086. [PMID: 36894788 PMCID: PMC10359207 DOI: 10.1007/s00392-023-02178-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Accepted: 02/22/2023] [Indexed: 03/11/2023]
Abstract
AIMS A high, Doppler-derived, tricuspid regurgitation velocity (TRV) indicates pulmonary hypertension, which may contribute to right ventricular dysfunction and worsening tricuspid regurgitation leading to systemic venous congestion, reflected by an increase in inferior vena cava (IVC) diameter. We hypothesized that venous congestion rather than pulmonary hypertension would be more strongly associated with prognosis. METHODS AND RESULTS 895 patients with chronic heart failure (CHF) (median (25th and 75th centile) age 75 (67-81) years, 69% men, LVEF 44 (34-55)% and NT-proBNP 1133 (423-2465) pg/ml) were enrolled. Compared to patients with normal IVC (< 21 mm) and TRV (≤ 2.8 m/s; n = 504, 56%), those with high TRV but normal IVC (n = 85, 9%) were older, more likely to be women and to have LVEF ≥ 50%, whilst those with dilated IVC but normal TRV (n = 142, 16%) had more signs of congestion and higher NT-proBNP. Patients (n = 164, 19%) with both dilated IVC and high TRV had the most signs of congestion and the highest NT-proBNP. During follow-up of 860 (435-1121) days, 239 patients died. Compared to those with both normal IVC and TRV (reference), patients with high TRV but normal IVC did not have a significantly increased mortality (HR: 1.41; CI: 0.87-2.29; P = 0.16). Risk was higher for patients with a dilated IVC but normal TRV (HR: 2.51; CI: 1.80-3.51; P < 0.001) or both a dilated IVC and elevated TRV (HR: 3.27; CI: 2.40-4.46; P < 0.001). CONCLUSION Amongst ambulatory patients with CHF, a dilated IVC is more closely associated with an adverse prognosis than an elevated TRV.

A machine learning-derived echocardiographic algorithm identifies people at risk of heart failure with distinct cardiac structure, function, and response to spironolactone: Findings from the HOMAGE trial. Eur J Heart Fail 2023; 25:1284-1289. [PMID: 37062878 DOI: 10.1002/ejhf.2859] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 03/31/2023] [Accepted: 04/11/2023] [Indexed: 04/18/2023] Open
Abstract
AIM An echocardiographic algorithm derived by machine learning (e'VM) characterizes pre-clinical individuals with different cardiac structure and function, biomarkers, and long-term risk of heart failure (HF). Our aim was the external validation of the e'VM algorithm and to explore whether it may identify subgroups who benefit from spironolactone. METHODS AND RESULTS The HOMAGE (Heart OMics in AGEing) trial enrolled participants at high risk of developing HF randomly assigned to spironolactone or placebo over 9 months. The e'VM algorithm was applied to 416 participants (mean age 74 ± 7 years, 25% women) with available echocardiographic variables (i.e. e' mean, left ventricular end-diastolic volume and mass indexed by body surface area [LVMi]). The effects of spironolactone on changes in echocardiographic and biomarker variables were assessed across e'VM phenotypes. A majority (>80%) had either a 'diastolic changes' (D), or 'diastolic changes with structural remodelling' (D/S) phenotype. The D/S phenotype had the highest LVMi, left atrial volume, E/e', natriuretic peptide and troponin levels (all p < 0.05). Spironolactone significantly reduced E/e' and B-type natriuretic peptide (BNP) levels in the D/S phenotype (p < 0.01), but not in other phenotypes (p > 0.10; pinteraction <0.05 for both). These interactions were not observed when considering guideline-recommended echocardiographic structural and functional abnormalities. The magnitude of effects of spironolactone on LVMi, left atrial volume and a type I collagen marker was numerically higher in the D/S phenotype than the D phenotype but the interaction test did not reach significance. CONCLUSIONS In the HOMAGE trial, the e'VM algorithm identified echocardiographic phenotypes with distinct responses to spironolactone as assessed by changes in E/e' and BNP.

Are non-invasive estimations of plasma volume an accurate measure of congestion in patients with chronic heart failure? EUROPEAN HEART JOURNAL. QUALITY OF CARE & CLINICAL OUTCOMES 2023; 9:281-292.

Abstract
AIMS We report associations between different formulae for estimating plasma volume status (PVS) and clinical and ultrasound markers of congestion in patients with chronic heart failure (CHF) enrolled in the Hull Lifelab registry. METHODS AND RESULTS Cohort 1 comprised patients with data on signs and symptoms at initial evaluation (n = 3505). Cohort 2 included patients with ultrasound assessment of congestion [lung B-line count, inferior vena cava (IVC) diameter, jugular vein distensibility (JVD) ratio] (N = 341). Two formulae for PVS were used: (a) Hakim (HPVS) and (b) Duarte (DPVS). Results were compared with clinical and ultrasound markers of congestion. Outcomes assessed were mortality and the composite of heart failure (HF) hospitalisation and all-cause mortality. In cohort 1, HPVS was associated with mortality [hazard ratio (HR) per unitary increase = 1.02 (1.01-1.03); P < 0.001]. In cohort 2, HPVS was associated with B-line count (HR) = 1.05 [95% confidence interval (CI) (1.01-1.08); P = 0.02] and DPVS with the composite outcome [HR = 1.26 (1.01-1.58); P = 0.04]. HPVS and DPVS were strongly related to haemoglobin concentration and HPVS to weight. After multivariable analysis, there were no strong or consistent associations between PVS and measures of congestion, severity of symptoms, or outcome. By contrast, log[NTproBNP] was strongly associated with all three. CONCLUSION Amongst patients with CHF, HPVS and DPVS are not strongly or consistently associated with clinical or ultrasound evidence of congestion, nor clinical outcomes after multivariable adjustment. They appear only to be surrogates of the variables from which they are calculated with no intrinsic clinical utility.

Effect of Spironolactone on QRS Duration in Patients at Risk for Heart Failure (from the HOMAGE Trial). Am J Cardiol 2023; 191:39-42. [PMID: 36634548 DOI: 10.1016/j.amjcard.2022.12.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 12/05/2022] [Accepted: 12/18/2022] [Indexed: 01/12/2023]
Abstract
The QRS duration can be easily obtained from a 12-lead electrocardiogram. Increased QRS duration reflects greater ventricular activation times and often ventricular dyssynchrony. Dyssynchrony causes an impairment of the global cardiac function and adversely affects the prognosis of patients with heart failure (HF). Little is known about the impact of pharmacologic therapies on the QRS duration, particularly for patients with presymptomatic HF with a preserved left ventricular (LV) ejection fraction (i.e., stage B HF with preserved ejection fraction [HFpEF]). The HOMAGE (Heart OMics in AGEing) trial enrolled patients at risk factors for developing HF and assigned them to receive either spironolactone or the usual care for approximately 9 months in a randomized manner. This analysis reports the effect of spironolactone on the QRS duration. A total of 525 patients was included in the analysis. The median (percentile25-75) QRS duration at baseline was 92 (84 to 106) ms. Spironolactone reduced the QRS duration at month 9 by -2.8, 95% confidence interval -4.6 to -1.0 ms, p = 0.003. No significant associations were found between month 9 changes in the QRS duration and corresponding changes in the LV ejection fraction, LV mass, LV end-diastolic volume, blood pressure, N-terminal pro-brain natriuretic peptide, and procollagen type I carboxy-terminal propeptide (all p >0.05). This analysis shows that for patients with stage B HFpEF, therapy with spironolactone for 9 months shortened the QRS duration, an effect that was not associated with reductions in LV mass or volume, supporting the hypothesis that spironolactone has direct beneficial effects to improve myocardial electrical activation in patients with stage B HFpEF.

Association between sacubitril/valsartan initiation and changes in left ventricular ejection fraction: Insights from ARIADNE registry. Int J Cardiol 2023; 370:279-286.

Abstract
AIMS We tested the hypothesis that initiation versus non-initiation of sacubitril/valsartan is associated with a more favorable subsequent change in left ventricular ejection fraction (LVEF) in a real-world setting. METHODS A prospective, non-randomized, double-arm, open-label, cohort study had been conducted across 687 centers in 17 European countries enrolling HFrEF patients aged ≥18 years with symptoms of HF (New York Heart Association [NYHA] II-IV) and "reduced LVEF". For the current analysis, 2602 patients with LVEF measured at baseline and follow-up were chosen, of which 860 (33%, mean age 67 years, 26% women) were started on sacubitril/valsartan at baseline and 1742 (67%, 68 years, 23% women) were not. Patients started on sacubitril/valsartan had higher NYHA class and lower LVEF. RESULTS LVEF increased from mean 32.7% to 38.1% in the sacubitril/valsartan group versus from 35.9% to 38.7% in the non-sacubitril/valsartan group (mean difference in increase 2.6%, p < 0.001). LVEF increased from baseline in 64% versus 53% of patients and increased by ≥5% (absolute %) in 50% versus 35% of patients in the sacubitril/valsartan versus non-sacubitril/valsartan groups, respectively. In the overall cohort, initiation of sacubitril/valsartan was independently associated with any increase in LVEF (adjusted odds ratio [OR] 1.49 [1.26-1.75]) and with increase by ≥5% (OR 1.65 [1.39-1.95]). CONCLUSION Initiating versus not initiating sacubitril/valsartan was independently associated with a greater subsequent increase in LVEF in this real-world setting. Reverse cardiac remodeling may be one mechanism of benefit of sacubitril/valsartan.

Abstract
Heart failure (HF) and chronic obstructive pulmonary disease (COPD) are common causes of breathlessness which frequently co-exist; one potentially exacerbating the other. Distinguishing between the two can be challenging due to their similar symptomatology and overlapping risk factors, but a timely and correct diagnosis is potentially lifesaving. Modern treatment for HF can substantially improve symptoms and prognosis for many patients and may have beneficial effects for patients with COPD. Conversely, while many inhaled treatments for COPD can improve symptoms and reduce exacerbations, there is conflicting evidence regarding the safety of some inhaled treatments for COPD in patients with HF. Here we explore the overlap between HF and COPD, examine the effect of one condition on the other, and address the challenges of managing patients with both conditions.

Abstract
BACKGROUND Whether revascularization by percutaneous coronary intervention (PCI) can improve event-free survival and left ventricular function in patients with severe ischemic left ventricular systolic dysfunction, as compared with optimal medical therapy (i.e., individually adjusted pharmacologic and device therapy for heart failure) alone, is unknown. METHODS We randomly assigned patients with a left ventricular ejection fraction of 35% or less, extensive coronary artery disease amenable to PCI, and demonstrable myocardial viability to a strategy of either PCI plus optimal medical therapy (PCI group) or optimal medical therapy alone (optimal-medical-therapy group). The primary composite outcome was death from any cause or hospitalization for heart failure. Major secondary outcomes were left ventricular ejection fraction at 6 and 12 months and quality-of-life scores. RESULTS A total of 700 patients underwent randomization - 347 were assigned to the PCI group and 353 to the optimal-medical-therapy group. Over a median of 41 months, a primary-outcome event occurred in 129 patients (37.2%) in the PCI group and in 134 patients (38.0%) in the optimal-medical-therapy group (hazard ratio, 0.99; 95% confidence interval [CI], 0.78 to 1.27; P = 0.96). The left ventricular ejection fraction was similar in the two groups at 6 months (mean difference, -1.6 percentage points; 95% CI, -3.7 to 0.5) and at 12 months (mean difference, 0.9 percentage points; 95% CI, -1.7 to 3.4). Quality-of-life scores at 6 and 12 months appeared to favor the PCI group, but the difference had diminished at 24 months. CONCLUSIONS Among patients with severe ischemic left ventricular systolic dysfunction who received optimal medical therapy, revascularization by PCI did not result in a lower incidence of death from any cause or hospitalization for heart failure.

Abstract
Abstract
Background
Increasing severity of impairment of left ventricular systolic dysfunction (LVSD) in patients with chronic heart failure (CHF) is associated with higher mortality. However, the relation between temporal changes in LVSD severity and long-term clinical outcome is unknown.
Purpose
We therefore investigated the effects of change of LVSD as measured by serial echocardiography on all-cause mortality in patients with CHF.
Methods
Patients with CHF defined as the presence of compatible symptoms and either at least moderate LVSD or NTproBNP >125 ng/L were enrolled. LVSD was qualitatively assessed as: none, mild, moderate, and severe. Echocardiography was performed at baseline and 12 months. The primary endpoint was all-cause mortality. Cox proportional hazard models were used to assess the relation between changes in LVSD and outcome. Hazard ratios (HR) are reported with 95% confidence intervals (CI).
Results
At baseline, 170 (11%) had no, 231 (16%) mild, 633 (43%) moderate and 453 (30%) severe LVSD. Amongst patients with either moderate or severe LVSD at baseline, 40% had improvement in function at 12 months (figure 1). Amongst patients with no LVSD at baseline, only 14% had deterioration of function. During subsequent median follow up of 2773 days, 868 patients died. Worsening of LVSD was associated with increasing all-cause mortality in patients with moderate LVSD and severe LVSD at baseline, but this was not significant after adjustment for covariables (table 1). Improvement of LVSD was independently associated with better survival in patients with moderate LVSD at baseline (HR 0.72 (95% CI: 0.53–0.98, p=0.04).
Conclusion
Greater severity of LVSD at baseline is associated with increasing likelihood of improvement. Amongst patients with moderate LVSD, improvement in LVSD is independently associated with survival.

Abstract
Abstract
Background
Evaluation of pulmonary arterial pressure (PAP) is recommended by guidelines to diagnose and monitor congestion in patients with heart failure (HF). However, the high compliance of the venous system might buffer the effects of a large increase in intravascular volume and delay an elevation in PAP. Therefore, measuring inferior vena cava (IVC) diameter by ultrasounds might add important information in patients with HF, regardless of PAP.
Aim
To evaluate the relationship between the IVC diameter and systolic PAP (PAsP) assessed by echocardiography with mortality in outpatients with HF.
Methods
We enrolled consenting out-patients attending a community HF clinic for initial diagnosis or follow-up in Kingston upon Hull, UK between 2009–2012. HF was defined as the presence of relevant symptoms and signs and objective evidence of cardiac dysfunction: either a left ventricular systolic function (LVEF) <50% or elevated amino-terminal pro-brain natriuretic peptide (NT-proBNP) ≥125 pg/ml. IVC was considered dilated when >2.0 cm, PAsP elevated when >35 mmHg.
Results
Amongst the 874 patients enrolled, median age was 75 years, 68% were men, median LVEF was 44% and median NT-proBNP was 1125 pg/ml. 468 patients (54%) had normal IVC and PAsP, 117 (13%) had normal IVC but elevated PAsP, 75 (8%) had dilated IVC but normal PAsP and 214 (25%) had both dilated IVC and elevated PAsP. Compared to those with normal IVC and PAsP, those with elevated PAsP but normal IVC were older, more likely to be women, and had higher LVEF and NT-proBNP, whilst those with dilated IVC but normal PAsP had similar age and LVEF, but more signs of congestion and higher NT-proBNP. Compared to those with both normal IVC and PAsP (reference), those with dilated IVC but normal PAsP (HR: 1.83; CI: 1.04–3.25; P=0.037) or elevated PAsP but normal IVC (HR: 1.88; CI: 1.25–2.85; P=0.003) had a similarly increased risk of death but those with a dilated IVC and elevated PAsP had the greatest risk (HR: 4.16; CI: 3.10–5.57; P<0.001).
Conclusion
A dilated IVC is associated with mortality even when PAsP is not elevated. Tailoring treatments to reduce IVC diameter is a strategy worth exploring to improve outcomes in outpatients with heart failure.

Abstract
AIMS ARIADNE aimed to assess the association between effects of sacubitril/valsartan and no sacubitril/valsartan treatment and clinical characteristics, functional capacity, and clinical outcomes (cause-specific mortality and hospitalizations) in outpatients with heart failure (HF) with reduced ejection fraction (HFrEF). METHODS ARIADNE was a prospective European registry of 9069 patients with HFrEF treated by office-based cardiologists or selected primary care physicians. Of the 8787 eligible for analysis, 4173 patients were on conventional HF treatment (non-S/V group), whereas 4614 patients were either on sacubitril/valsartan treatment at enrolment or started sacubitril/valsartan within 1 month of enrolment (S/V group). We also generated a restricted analysis set (rS/V) including only those 2108 patients who started sacubitril/valsartan treatment within the month prior to or after enrolment. RESULTS At the baseline, average age of patients enrolled in the study was 68 years, and 23.9% (2099/8787) were female. At the baseline, the proportions of patients with New York Heart Association (NYHA) Class III symptoms were 30.9 (1288/4173), 42.8 (1974/4614), and 48.2% (1015/2108), in non-S/V, S/V, and rS/V groups, respectively. After 12 months of treatment, the proportion of patients with NYHA Class III at baseline who improved to Class II was 32.0% (290/907) in the non-S/V group vs. 46.3% (648/1399) in S/V group and 48.7% (349/717) in rS/V group. The overall mortality rate was 5.0 per 100 patient-years. Rates of HF hospitalizations were high (20.9, 20.3, and 21.2 per 100 patient-years in the non-S/V, S/V, and rS/V groups, respectively). Emergency room visits without hospitalization occurred in 3.9, 3.2, and 3.9% of patients in the non-S/V, S/V, and rS/V groups, respectively. CONCLUSIONS This large HFrEF European registry provides a contemporary outcome profile of outpatients with HFrEF treated with or without sacubitril/valsartan. In a real-world setting, sacubitril/valsartan was associated with an improvement of symptoms in patients with HFrEF compared with the conventional HFrEF treatment.

Dyskalemia in people at increased risk for heart failure: findings from the heart 'OMics' in AGEing (HOMAGE) trial. ESC Heart Fail 2022; 9:4352-4357. [PMID: 36065795 PMCID: PMC9773649 DOI: 10.1002/ehf2.14086] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 05/24/2022] [Accepted: 07/08/2022] [Indexed: 01/19/2023] Open
Abstract
AIMS In people at risk of heart failure (HF) enrolled in the Heart 'OMics' in AGEing (HOMAGE) trial, spironolactone reduced circulating markers of collagen synthesis, natriuretic peptides, and blood pressure and improved cardiac structure and function. In the present report, we explored factors associated with dyskalaemia. METHODS AND RESULTS The HOMAGE trial was an open-label study comparing spironolactone (up to 50 mg/day) versus standard care in people at risk for HF. After randomization, serum potassium was assessed at 1 and 9 months and was defined as low when ≤3.5 mmol/L (hypokalaemia) and high when ≥5.5 mmol/L (hyperkalaemia). Multivariable logistic regression models were constructed to identify clinical predictors of dyskalaemia. A total of 513 participants (median age 74 years, 75% men, median estimated glomerular filtration rate 71 mL/min/1.73 m2 ) had serum potassium available and were included in this analysis. At randomization, 88 had potassium < 4.0 mmol/L, 367 had potassium 4.0-5.0 mmol/L, and 58 had potassium > 5.0 mmol/L. During follow-up, on at least one occasion, a serum potassium < 3.5 mmol/L was observed in 6 (1.2%) and <4.0 mmol/L in 46 (9%) participants, while a potassium > 5.0 mmol/L was observed in 38 (8%) and >5.5 mmol/L in 5 (1.0%) participants. The median (percentile25-75 ) increase in serum potassium with spironolactone during the study was 0.23 (0.16; 0.29) mmol/L. Because of the low incidence of dyskalaemia, for regression analysis, hypokalaemia and hyperkalaemia thresholds were set at <4.0 and >5.0 mmol/L, respectively. The occurrence of a serum potassium > 5.0 mmol/L during follow-up was positively associated with the presence of diabetes mellitus {odds ratio [OR]: 1.21 [95% confidence interval (CI) 2.14; 3.79]} and randomization to spironolactone (OR: 2.83 [95% CI 1.49; 5.37]). Conversely, the occurrence of a potassium concentration < 4.0 mmol/L was positively associated with the use of thiazides (OR: 2.39 [95% CI 1.32; 4.34]), blood urea concentration (OR: 2.15 [95% CI 1.34; 3.39] per 10 mg/dL), and history of hypertension (OR: 2.32 [95% CI 1.02; 5.29]) and negatively associated with randomization to spironolactone (OR: 0.30 [95% CI 0.18; 0.52]). CONCLUSIONS In people at risk for developing HF and with relatively normal renal function, spironolactone reduced the risk of hypokalaemia and, at the doses used, was not associated with the occurrence of clinically meaningful hyperkalaemia.

Overstimulation of the ergoreflex—A possible mechanism to explain symptoms in long COVID. Front Cardiovasc Med 2022; 9:940832.

Abstract
Long COVID refers to a multitude of symptoms that persist long after SARS-CoV-2 infection. Fatigue and breathlessness are the most common symptoms of long COVID across a range of studies. They are also cardinal symptoms of chronic heart failure (CHF). In this review, we propose that fatigue and breathlessness in patients with long COVID may be explained by skeletal muscle abnormalities, in a manner similar to patients with CHF. The ergoreflex is a cardiorespiratory reflex activated by exercise, which couples ventilation and cardiovascular function to exercise intensity. At least part of the symptomatology of CHF is related to abnormal skeletal muscle and an enhanced ergoreflex, resulting in heightened sympathetic, vasoconstrictor and ventilator drives. Similarly, SARS-CoV-2 infection results in a hyperinflammatory and hypercatabolic state. This leads to reduction in skeletal muscle mass and altered function. We postulate that the ergoreflex is chronically overstimulated, resulting in fatigue and breathlessness. Exercise training preserves muscle mass and function as well as reduces ergoreflex activation; therefore may have a role in improving symptoms associated with long COVID. Should the ergoreflex be proven to be an important pathophysiological mechanism of long COVID, tailored exercise interventions should be trialed with the aim of improving both symptoms and perhaps outcomes in patients with long COVID.

Abstract
AIMS Risk changes with the progression of disease and the impact of treatment. We developed a dynamic risk stratification Markov chain model using artificial intelligence in patients with chronic heart failure (CHF). METHODS AND RESULTS We described the pattern of behaviour among 7496 consecutive patients assessed for suspected HF. The following mutually exclusive health states were defined and assessed every 4 months: death, hospitalization, outpatient visit, no event, and leaving the service altogether (defined as no event at any point following assessment). The observed figures at the first transition (4 months) weres 427 (6%), 1559 (21%), 2254 (30%), 1414 (19%), and 1842 (25%), respectively. The probabilities derived from the first two transitions (i.e. from baseline to 4 months and from 4 to 8 months) were used to construct the model. An example of the model's prediction is that at cycle 4, the cumulative probability of death was 14%; leaving the system, 37%; being hospitalized between 12 and 16 months, 10%; having an outpatient visit, 8%; and having no event, 31%. The corresponding observed figures were 14%, 41%, 10%, 15%, and 21%, respectively. The model predicted that during the first 2 years, a patient had a probability of dying of 0.19, and the observed value was 0.18. CONCLUSIONS A model derived from the first 8 months of follow-up is strongly predictive of future events in a population of patients with chronic heart failure. The course of CHF is more linear than is commonly supposed, and thus more predictable.

The association between markers of type I collagen synthesis and echocardiographic response to spironolactone in patients at risk of heart failure: findings from the HOMAGE trial. Eur J Heart Fail 2022; 24:1559-1568. [PMID: 35703355 DOI: 10.1002/ejhf.2579] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2022] [Revised: 06/07/2022] [Accepted: 06/08/2022] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND Procollagen type I C-terminal propeptide (PICP) and procollagen type III N-terminal propeptide (PIIINP) are markers reflecting collagen synthesis in cardiac fibrosis. However, they may be influenced by the presence of noncardiac comorbidities (e.g., ageing, obesity, renal impairment). Understanding the associations between markers of collagen synthesis and abnormalities of cardiac structure and function is important to screen for myocardial fibrosis and monitor the antifibrotic effect of medications. METHODS The HOMAGE (Heart OMics in Aging) trial showed that spironolactone decreased serum PICP concentrations and improved cardiac remodeling over 9 months in a population at risk of developing heart failure (HF). We evaluated the associations between echocardiographic variables, PICP, PIIINP and galectin-3 at baseline and during the course of the trial. RESULTS Among 527 individuals (74±7years, 26% women), median serum concentrations of PICP, PIIINP and galectin-3 were 80.6μg/L (65.1-97.0), 3.9μg/L (3.1-5.0) and 16.1μg/L (13.5-19.7), respectively. After adjustment for potential confounders, higher serum PICP was significantly associated with left ventricular hypertrophy, left atrial enlargement, and greater ventricular stiffness (all p-values<0.05), whereas serum PIIINP and galectin-3 were not (all p-values>0.05). In patients treated with spironolactone, a reduction in serum PICP during the trial was associated with a decrease in E/e' (adjusted-beta [95% CI] =0.93 [0.14-1.73]; p=0.022). CONCLUSIONS In individuals at high risk of developing HF, serum PICP was associated with cardiac structural and functional abnormalities, and a decrease in PICP with spironolactone was correlated with improved diastolic dysfunction as assessed by E/e'. In contrast, no such associations were present for serum PIIINP and galectin-3.

Effects of sildenafil on symptoms and exercise capacity for heart failure with reduced ejection fraction and pulmonary hypertension (The SilHF study): A randomised placebo-controlled multicentre trial. Eur J Heart Fail 2022; 24:1239-1248. [PMID: 35596935 PMCID: PMC9544113 DOI: 10.1002/ejhf.2527] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 04/26/2022] [Accepted: 04/30/2022] [Indexed: 11/25/2022] Open
Abstract
Aims Pulmonary hypertension (PHT) may complicate heart failure with reduced ejection fraction (HFrEF) and is associated with a substantial symptom burden and poor prognosis. Sildenafil, a phosphodiesterase‐5 (PDE‐5) inhibitor, might have beneficial effects on pulmonary haemodynamics, cardiac function and exercise capacity in HFrEF and PHT. The aim of this study was to determine the safety, tolerability, and efficacy of sildenafil in patients with HFrEF and indirect evidence of PHT. Methods and results The Sildenafil in Heart Failure (SilHF) trial was an investigator‐led, randomized, multinational trial in which patients with HFrEF and a pulmonary artery systolic pressure (PASP) ≥40 mmHg by echocardiography were randomly assigned in a 2:1 ratio to receive sildenafil (up to 40 mg three times/day) or placebo. The co‐primary endpoints were improvement in patient global assessment by visual analogue scale and in the 6‐min walk test at 24 weeks. The planned sample size was 210 participants but, due to problems with supplying sildenafil/placebo and recruitment, only 69 patients (11 women, median age 68 (interquartile range [IQR] 62–74) years, median left ventricular ejection fraction 29% (IQR 24–35), median PASP 45 (IQR 42–55) mmHg) were included. Compared to placebo, sildenafil did not improve symptoms, quality of life, PASP or walk test distance. Sildenafil was generally well tolerated, but those assigned to sildenafil had numerically more serious adverse events (33% vs. 21%). Conclusion Compared to placebo, sildenafil did not improve symptoms, quality of life or exercise capacity in patients with HFrEF and PHT.

Abstract
BACKGROUND Left ventricular ejection fraction (LVEF) can provide hemodynamic information and may influence the response to spironolactone and other heart failure (HF) therapies. AIMS To study the patient characteristics and circulating protein associations with LVEF, and whether LVEF influenced the response to spironolactone. METHODS HOMAGE enrolled patients aged >60 years at high risk of developing HF with a LVEF ≥45%. 527 patients were randomized to either spironolactone or standard-of-care for ≈9 months. 276 circulating proteins were measured using Olink® technology. RESULTS 364 patients had available LVEF determined by the Simpson's bi-plane method. The respective LVEF tertiles were: Tertile1:<60% (N = 122), Tertile2:60%-65% (N = 121), and Tertile3:>65% (N = 121). Patients with a LVEF>65% had smaller LV chamber size and volumes, and lower natriuretic peptide levels. Compared to patients with a LVEF<60%, those with LVEF>65% had higher levels of circulating c-c motif chemokine ligand-23 and interleukin-8, and lower levels of tissue plasminogen activator, BNP, S100 calcium binding protein A12, and collagen type I alpha 1 chain (COL1A1). Spironolactone significantly reduced the circulating levels of BNP and COL1A1 without significant treatment-by-LVEF heterogeneity: BNP change β = -0.36 Log2 and COL1A1 change β = -0.16 Log2 (P < 0.0001 for both; interactionP>0.1 for both). Spironolactone increased LVEF from baseline to month 9 by 1.1%, P = 0.007. CONCLUSION Patients with higher LVEF had higher circulating levels of chemokines and inflammatory markers and lower levels of stretch, injury, and fibrosis markers. Spironolactone reduced the circulating levels of natriuretic peptides and type 1 collagen, and increased LVEF. This article is protected by copyright. All rights reserved.

Abstract
AIMS Hypochloraemia is common in patients hospitalized with heart failure (HF) and associated with a high risk of adverse outcomes during admission and following discharge. We assessed the significance of changes in serum chloride concentrations in relation to serum sodium and bicarbonate concentrations during admission in a cohort of 1002 consecutive patients admitted with HF and enrolled into an observational study based at a single tertiary centre in the UK. METHODS AND RESULTS Hypochloraemia (<96 mmol/L), hyponatraemia (<135 mmol/L), and metabolic alkalosis (bicarbonate >32 mmol/L) were defined by local laboratory reference ranges. Outcomes assessed were all-cause mortality, all-cause mortality or all-cause readmission, and all-cause mortality or HF readmission. Cox regression and Kaplan-Meier curves were used to investigate associations with outcome. During a median follow-up of 856 days (interquartile range 272-1416), discharge hypochloraemia, regardless of serum sodium, or bicarbonate levels was associated with greater all-cause mortality [hazard ratio (HR) 1.44, 95% confidence interval (CI) 1.15-1.79; P = 0.001], all-cause mortality or all-cause readmission (HR 1.26, 95% CI 1.04-1.53; P = 0.02), and all-cause mortality or HF readmission (HR 1.41, 95% CI 1.14-1.74; P = 0.002) after multivariable adjustment. Patients with concurrent hypochloraemia and natraemia had lower haemoglobin and haematocrit, suggesting congestion; those with hypochloraemia and normal sodium levels had more metabolic alkalosis, suggesting decongestion. CONCLUSION Hypochloraemia is common at discharge after a hospitalization for HF and is associated with worse outcome subsequently. It is an easily measured clinical variables that is associated with morbidity or mortality of any cause.

Biomarker-based assessment of collagen cross-linking identifies patients at risk of heart failure more likely to benefit from spironolactone effects on left atrial remodelling. Insights from the HOMAGE clinical trial. Eur J Heart Fail 2021; 24:321-331.

Abstract
AIMS The HOMAGE randomized trial found that spironolactone reduced left atrial volume index (LAVI), E:A ratio, and a marker of collagen type I synthesis (procollagen type I C-terminal propeptide) in patients at risk of heart failure (HF). Previous trials showed that patients with HF, preserved ejection fraction and low serum collagen type I C-terminal telopeptide to matrix metalloproteinase-1 ratio (CITP:MMP-1), associated with high collagen cross-linking, had less improvement in diastolic function with spironolactone. We evaluated the interaction between serum CITP:MMP-1 and spironolactone on cardiac function in the HOMAGE trial. METHODS AND RESULTS Patients at risk of HF were randomized to spironolactone (n = 260) or not (n = 255). Blood sampling and echocardiography were done at baseline, one and nine months. CITP:MMP-1 was used as an indirect measure of collagen cross-linking. Higher baseline CITP:MMP-1 (i.e. lower collagen cross-linking) was associated with greater reductions in LAVI with spironolactone at both one (p = 0.003) and nine (p = 0.01) months, but no interaction was observed for E:A ratio. Spironolactone reduced LAVI after one and nine months only for those patients in the third tertile of CITP:MMP-1 (estimated lowest collagen cross-linking) [mean differencesspiro/control : -1.77 (95% confidence interval, CI -2.94 to -0.59) and -2.52 (95% CI -4.46 to -0.58) mL/m2 ; interaction pacross-tertiles = 0.005; interaction pthird tertile = 0.008] with a similar trend for N-terminal pro-B-type natriuretic peptide which was consistently reduced by spironolactone only in the lowest collagen cross-linking tertile [mean differencesspiro/control : -0.47 (95% CI -0.66 to -0.28) and -0.31 (95% CI -0.59 to -0.04) ng/L; interaction pacross-tertiles = 0.09; interaction pthird tertile < 0.001]. CONCLUSIONS These findings suggest that, for patients at risk of HF, the effects of spironolactone on left atrial remodelling may be more prominent in patients with less collagen cross-linking (indirectly assessed by serum CITP:MMP-1).

Abstract
Heart failure (HF) with reduced ejection fraction is common following acute myocardial infarction (MI), and active medical management can have a profound impact on prognosis. Reviewing relevant clinical trials, we focus on the pharmacological management of left ventricular systolic dysfunction (LVSD) following an acute MI, although there is overlap with the pharmacological management of chronic HF due to reduced ejection fraction. Angiotensin converting enzyme (ACE) inhibitors, beta-blockers, and mineralocorticoid receptor antagonists are the mainstay of medical management in patients with LVSD post MI; there may also be a role for anticoagulation. Sacubitril-valsartan (angiotensin receptor neprilysin inhibitor) has not yet been shown to be superior to an ACE inhibitor in reducing cardiovascular mortality and HF events in patients with LVSD post MI. Large randomised trials evaluating sodium glucose transporter 2 (SGLT-2) inhibitors in LVSD post MI are ongoing.

Abstract
Introduction Digoxin is used in patients with chronic heart failure (CHF) who remain symptomatic despite optimal medical treatment. Impaired renal function is commonly associated with CHF. We investigated the relation between digoxin use and change in renal function over time in patients with CHF. Methods One thousand two hundred forty-one patients with symptoms and signs of CHF (average age 72 years (64% male), and median NTproBNP 1426 ng/l (interquartile range 632–2897) were divided into four groups: never on digoxin (N = 394); digoxin throughout (N = 449); started digoxin at some point after baseline (N = 367); and stopped digoxin at some point after baseline (N = 31). The rate of change of estimated glomerular filtration rate (eGFR) was calculated using linear regression. Results Patients on digoxin throughout had a significantly greater rate of decline in eGFR per year than patients not on digoxin throughout (mean (± standard deviation); − 5 (14) ml/min/1.73m2 per year v − 2 (11) ml/min/1.73m2 per year, P = 0.02). In those patients who started digoxin during follow up, there was no significant difference in the rate of decline in eGFR before and after starting digoxin. There was no correlation between baseline eGFR (or rate of decline in eGFR) and age, haemoglobin or NTproBNP. Compared to patients taking both angiotensin-converting-enzyme inhibitor (ACEi) or angiotensin receptor blockers (ARB) and beta-blocker (BB), patients who were not taking an ACEi/ARB or BB had a numerically faster rate of decline in eGFR, although this was not statistically significant. Conclusion The rate of decline in renal function is greater in patients with CHF who are taking digoxin.

Abstract
Abstract
Background
Recently, the Heart Failure Association (HFA) of the European Society of Cardiology (ESC) proposed a four-domain approach to assess frailty in patients with heart failure (HF), to tailor treatment and potentially improve outcomes. The efficacy of such approach in detecting frailty and predicting outcome in patients with HF is unknown.
Aim
To study the prevalence and prognostic value of four different types of frailty deficits: clinical, physical, cognitive and social frailty in ambulatory patients with HF.
Methods
We assessed prospectively consecutive patients attending a routine follow-up visit. Patients with ≥5 non-HF comorbidities were classified as having a clinical deficit. Those who scored ≥3 using the Fried criteria were classified as having a physical deficit. Those who failed to complete a clock test accurately were classified as having a cognitive deficit. Those who lived alone or in a residential home were classified as having a social deficit. All patients were followed for a minimum of 1 year. The primary end point is all-cause mortality.
Results
We enrolled 467 patients (67% male, median (25th–75th centile) age 76 (69–82) years, median (25th–75th centile) NT-proBNP 1156 (469–2463) ng/L). 65% of patients had clinical deficits, 52% had a physical deficit, 39% had a social deficit and 18% had a cognitive deficit. 28% had 2, 19% had 3, 8% of patients had all 4 deficits; 16% had none. An increasing number of frailty deficits was associated with worse symptoms, higher NT-proBNP and less likelihood of being prescribed guideline-indicated HF treatment.
During a median follow-up of 554 days, 82 patients died. The presence of any frailty deficit was associated with increased risk of mortality. (Figure 1) The more frailty deficit a patient had, the higher the risk of mortality (Figure 2). A base model (including age, body mass index, NYHA class and log [NT-proBNP]) for predicting mortality at 1 year achieved a C-statistic of 0.78. Addition of all four deficits improved the performance of the base model (C-statistic = 0.82).
Conclusion
Clinical, physical, cognitive and social deficits are common in patients with HF and are associated with a poor outcome. Future studies should evaluate how a domain-based approach can be used to optimise care for frail patients with HF.

The prevalence and clinical associations of ultrasound measures of congestion in patients at risk of developing heart failure. Eur J Heart Fail 2021; 23:1831-1840. [PMID: 34632680 DOI: 10.1002/ejhf.2353] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Revised: 09/19/2021] [Accepted: 09/21/2021] [Indexed: 12/28/2022] Open
Abstract
AIMS Congestion is a cardinal feature of untreated heart failure (HF) and might be detected by ultrasound (US) before overt clinical signs appear. METHODS AND RESULTS We investigated the prevalence and clinical associations of subclinical congestion in 238 patients with at least one clinical risk factor for HF (diabetes, ischaemic heart disease, or hypertension) using three US variables: (i) inferior vena cava (IVC) diameter; (ii) jugular vein distensibility (JVD) ratio (the ratio of the jugular vein diameter during the Valsalva manoeuvre to that at rest); (iii) the number of B-lines from a 28-point lung US. US congestion was defined as IVC diameter > 2.0 cm, JVD ratio < 4.0 or B-lines count > 14. The prevalence of subclinical congestion (defined as at least one positive US marker of congestion) was 30% (13% by IVC diameter, 9% by JVD ratio and 13% by B-line quantification). Compared to patients with no congestion on US, those with at least one marker had larger left atria and higher plasma concentrations of natriuretic peptides. Patients with raised plasma N-terminal pro-B-type natriuretic peptide/B-type natriuretic peptide had a lower JVD ratio (7.69 vs. 8.80; P = 0.05) and more often had at least one lung B-line (74% vs. 63%; P = 0.05). However, plasma natriuretic peptide concentrations were more closely related to left atrial volume than other US measures of congestion. CONCLUSIONS Subclinical evidence of congestion by US is common in patients with clinical risk factors for HF. Whether these measurements provide additional value for predicting the development of HF and its prevention deserves consideration.

Abstract
Therapy to activate bone formation is required to reverse and restore the damaged bone architecture found in women with postmenopausal osteoporosis. The osteoanabolic drugs include teriparatide, which has been available for several years, and abaloparatide and romosozumab, novel osteoanabolic drugs that have become available more recently. By stimulating bone formation, these drugs produce greater increases in bone mass and bone strength, and they do so more quickly compared to the commonly used anti-remodeling (also called antiresorptive) drugs such as bisphosphonates. In head-to-head trials, teriparatide and romosozumab reduce fracture risk more effectively than do oral bisphosphonates in women with osteoporosis and high fracture risk. Osteoanabolic drugs have little role in the prevention of bone loss during early menopause, but they have an important place in the treatment of women at very high risk of fracture or who remain at high fracture risk after a course of bisphosphonate therapy. Primarily because of the high cost of the drugs, these therapies are initiated by specialists rather than primary-care physicians in most countries. This review will present the evidence for efficacy and safety of these drugs so that clinicians may discern their appropriate use when caring for postmenopausal women with osteoporosis.

A comparison of non-invasive methods of measuring body composition in patients with heart failure: a report from SICA-HF. ESC Heart Fail 2021; 8:3929-3934. [PMID: 34216106 PMCID: PMC8497207 DOI: 10.1002/ehf2.13402] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2020] [Revised: 04/15/2021] [Accepted: 04/22/2021] [Indexed: 12/04/2022] Open
Abstract
Background Cachexia is common in patients with chronic heart failure and is associated with poor prognosis. How best to measure body composition is not clear. Methods and results We characterized body composition in 120 patients with chronic heart failure: mean (SD) age 70 (10) years, left ventricular ejection fraction 44 (10) %, and median (Q1–Q3) N‐terminal pro B‐type natriuretic peptide 845 (355–1368) ng/L. We measured body composition using dual‐energy X‐ray absorptiometry (DEXA) and a multi‐frequency bioelectrical impedance analysis (BIA) device (Tanita BIA MC‐180MA). Mean (SD) fat mass (FM) was 27.2 (11.7) kg by BIA and 32.3 (12.2) kg by DEXA (mean difference −5.1 kg, 95% limits of agreement: −11.7, 1.5; 4% of values outside limit of agreement); mean (SD) lean mass (LM) was 56.6 (10.9) kg by BIA and 51.1 (9.9) kg by DEXA (mean difference 5.5 kg, 95% limits of agreement: −1.3, 12.3; 6% of values outside limit of agreement); and mean (SD) bone mass (BM) was 3.0 (0.5) kg by BIA and 2.8 (0.6) kg by DEXA (mean difference 0.2 kg, 95% limits of agreement: −0.5, 0.8; 5% of values outside limit of agreement). There was a close correlation between DEXA and BIA for both LM and FM (LM: r = 0.95, P < 0.001; FM: r = 0.96, P < 0.001) but less so for BM (r = 0.84, P < 0.001). Both DEXA and BIA body composition measurements correlated well with other measures of body size (body mass index, hip circumference, and waist circumference). Conclusions There are differences in the measurements of FM, LM, and BM between the two techniques, which should not be used interchangeably.

Identification of sex-specific biomarkers predicting new-onset heart failure. ESC Heart Fail 2021; 8:3512-3520. [PMID: 34156155 PMCID: PMC8497379 DOI: 10.1002/ehf2.13476] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 05/20/2021] [Accepted: 06/01/2021] [Indexed: 01/06/2023] Open
Abstract
Aims Heart failure (HF) is common in both men and women, yet disease pathophysiology, presentation, and progression differ between sexes. Studies addressing whether biomarkers predict new onset HF sex‐specifically are scarce. This study therefore aims to test the sex‐specificity of 252 protein biomarkers for new‐onset HF. Methods and results A matched case–control design in patients selected from cohorts within the HOMAGE consortium was used. Cases (new‐onset HF, n = 562) and controls (n = 780) were matched for cohort (PREDICTOR, HEALTH‐ABC, & PROSPER), follow‐up time (defined as time from entry to incident HF), and age. Incident HF was defined as first hospitalization for HF. Targeted plasma proteins (n = 252) were measured using Proximity Extension Assay technology from O‐link. To look for sex differences for new onset HF, we adjusted for cohort, age, and baseline clinical parameters. At baseline, women had a biomarker profile reflecting activated metabolism and immune responses. However, none of the biomarkers had a significant interaction with sex in predicting new onset HF, but four biomarkers had a trend towards sex‐specificity (P < 0.013). E‐selectin and interleukin 1 receptor antagonist were more female‐specific, whereas IL17A and CHIT1 tended to be male sex‐specific for incident HF. Conclusions The majority of biomarkers associated with incident HF did not significantly differ between women and men, despite clear differences in biomarkers at baseline.
