Twin peaks diversity with sacubitril/valsartan treatment responses in cardiomyopathic heart failure patients of non-ischemic compared to ischemic etiologies

Abstract Background Ischemic cardiomyopathy (ICM) has been associated with increased mortality when compared with non-ischemic cardiomyopathy (NICM) from several heart failure (HF) cohorts. Instead, PARADIGM study demonstrated similar event rates of cardiovascular (CV) death, all-cause mortality and HF readmissions between ICM and NICM patients. Although the beneficiary effect of sacubitril/valsartan (SAC/VAL) compared to enalapril on these endpoints was consistent across etiologic categories, PARADIGM study did not analyze the effect of ventricular remodeling of SAC/VAL on patients with different HF etiologies, which may significantly affect treatment outcomes. Purpose We aim to compare alterations of left ventricular ejection fraction (LVEF) following SAC/VAL treatment and its association with clinical outcomes in patients with different HF etiologies. Methods Treatment with angiotensin receptor neprilysin inhibitor for Taiwan heart failure patients (TAROT-HF) study is a multicenter study which enrolled 1552 patients with LVEF <40%, whom had been on SAC/VAL treatment from 9 hospitals between 2017 and 2018. After excluding patients without having follow-up echocardiographic studies, patients were grouped by HF etiologies and by LVEF changes following treatment for 8-month period. LVEF improvement ≥15% was defined as “significant improvement”, 5–15% as “marginal improvement”, and <5% or worse as “lack of improvement”. The primary endpoint was a composite of CV death or a first hospitalization for HF. Mean follow-up period was 726 days. Results A total of 1230 patients were analyzed. Patients with ICM were significantly older, more male, and prone to have associated hypertension and diabetes. On the other hand, patients with NICM had lower LVEF and higher likelihood of atrial fibrillation. LVEF increase was significantly greater in patients with NICM compared to those with ICM (11.2±12.4% vs. 6.9±9.8, p<0.001). The effect of ventricular remodeling of SAC/VAL on patients with NICM showed twin peaks diversity (Significant improvement 37.1%, lack of improvement 42.3%), whereas in patients with ICM the proportions of significant, marginal and lack of improvement groups were 19.4%, 28.2% and 52.4%, respectively. The primary endpoint showed twin peaks diversity also in patients with NICM in line with LVEF changes: adjusted HR for patients with NICM and significant improvement was 0.41 (95% CI 0.29–0.57, p<0.001), for patients with NICM and lack of improvement was 1.54 (95% CI 1.22–1.94, p<0.001). Analyses for CV death, all-cause mortality, and HF readmission demonstrated consistent results. Conclusion Patients with NICM had higher degree of LVEF improvement than those with ICM following SAC/VAL treatment, and significant improvement of LVEF in NICM patients may indicate favorable outcome. NICM patients without response to SAC/VAL treatment should serve as an indicator for poor clinical outcome and warranted meticulous HF management.

Background: Past data suggest ischemic cardiomyopathy (ICM) is associated with worse prognosis when compared to non-ischemic cardiomyopathy(NICM). With advances in heart failure management, this relationship deserves a fresh look. We hypothesize that all cause mortality from NICM is lower when compared to ICM over five year period. Methods: We retrospectively studied consecutive heart failure patients with left ventricular ejection fraction(EF) less than 35% admitted to Einstein Medical Center Philadelphia between 01/01/2007 to 12/31/2007. Data pertaining to patient demographics and clinical characteristics were obtained. All cause mortality was obtained at 5 years using hazard ratio to account for time to event. Results: The final cohort consisted of 360 patients of which 63%(224 of 360) had NICM. Mean age was 61±16 years for NICM and 66±11 yrs for ICM. African Americans constituted 83%(185 of 224) of NICM and 59%(80 of 136) of ICM. The clinical characteristics are as shown in the table. There were 160 deaths over the follow up period. Age, CKD, dyslipidemia and EF were significant predictors of mortality. ICM cohort had 81 deaths out of 136(60%) as compared to 85 out of 185((39%) in NICM over the follow up period. However, when adjusted for age, DM, CKD and days of follow-up, there was no statistically significant difference in mortality between the two groups over the five year follow up period. Conclusions: In this study, there was no significant mortality difference between ICM and NICM. We also found that despite advances in heart failure management in the last two decades, in clinical practice they are under-utilized.

All Cause Mortality

Abstract Background Heart failure patients with diabetes mellitus (DM) have a higher risk for all-cause mortality and also for sudden cardiac death. We lack data on the effect of adding an implantable cardioverter defibrillator (ICD) to cardiac resynchronization therapy (CRT) on all-cause mortality in diabetic heart failure patients. Purpose We aimed to investigate the risk of DM on all-cause mortality in CRT patients, and to examine the beneficial effect of adding an ICD on all-cause mortality by left ventricular ejection fraction in CRT patients with or without DM. Methods We examined retrospectively 2525 patients who underwent CRT implantation based on the current guidelines at our clinic between June 2000 and September 2018, of which 928 (36%) had diabetes. The primary endpoint was all-cause mortality, also expressed as events per 100 person-year by quintiles of ejection fraction (EF) with or without an ICD or DM. Time to event data was investigated by Kaplan Meier and multivariate Cox regressional analysis. Results During our mean follow-up time of 4.6 years, 1432 (56%) patients reached the primary endpoint, of which 553 (38%) had DM. In the DM group, hypertension (82% vs. 66%; p‹0.01), ischemic etiology (56% vs. 44%; p‹0.01), myocardial infarction (43% vs. 36%; p‹0.01) was more frequent compared to non-DM group. There was no difference between the two groups regarding the implantation of an ICD (54% vs. 53%; p = 0,84). Those with DM showed a 25% higher risk of all-cause mortality (HR 1.25; 95% CI 1.12-1.40; p‹0.01), also observable after adjusting for relevant clinical covariates such as age, gender, atrial fibrillation and the addition of an ICD (HR 1.17; 95% CI 1.06-1.31; p‹0.01). Examined as all-cause mortality per 100 person-year follow up, patients with EF›30% and DM (13,7 events/ 100 person-year follow-up for an EF 30-35%) showed similar risk as those without DM and a severely impaired left ventricular function with EF‹25% (14 events/100 person-year follow-up for an EF <25%). Investigating the composite end-point of all-cause mortality and heart failure hospitalization, those with DM showed a 21% higher risk than non-DM CRT patients (HR 1.21; CI 1.09-1.34; p = 0 < 0.001). Adding an ICD for CRT patients with DM reduces the risk of all-cause mortality significantly by 32% (HR 0,68; CI 0,56 to 0,82; p < 0.001) during the first six years but diminished on longer follow-up time. Conclusions Diabetes was found as an independent predictor of all-cause mortality in CRT patients. Those with a left ventricular ejection fraction above 30% have comparable risk of mortality as non-diabetic patients with a severely impaired left ventricular function. In diabetic CRT patients the addition of an ICD reduces the risk of all-cause mortality mostly seen in the first six years. These findings might implicate the relevance of adding an ICD to CRT even at a higher ejection fraction in those with severe comorbidities such as diabetes. Abstract Figure.

Abstract Background Lower systolic blood pressure (SBP) at admission or discharge was associated with poor outcomes in patients with heart failure and preserved ejection fraction (HFpEF). However, the optimal long-term SBP for HFpEF was less clear. Purpose To examine the association of long-term SBP and all-cause mortality among patients with HFpEF. Methods We analyzed participants from the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) study. Participants had at least two SBP measurements of different times during the follow-up were included. Long-term SBP was defined as the average of all SBP measurements during the follow-up. We stratified participants into four groups according to long-term SBP: <120mmHg, ≥120mmHg and <130mmHg, ≥130mmHg and <140mmHg, ≥140mmHg. Multivariable adjusted Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CI) for all-cause mortality associated with SBP level. To assess for nonlinearity, we fitted restricted cubic spline models of long-term SBP. Sensitivity analyses were conducted by confining participants with history of hypertension or those with left ventricular ejection fraction≥50%. Results The 3338 participants had a mean (SD) age of 68.5 (9.6) years; 51.4% were women, and 89.3% were White. The median long-term SBP was 127.3 mmHg (IQR 121–134.2, range 77–180.7). Patients in the SBP of <120mmHg group were older age, less often female, less often current smoker, had higher estimated glomerular filtration rate, less often had history of hypertension, and more often had chronic obstructive pulmonary disease and atrial fibrillation. After multivariable adjustment, long-term SBP of 120–130mmHg and 130–140mmHg was associated with a lower risk of mortality during a mean follow-up of 3.3 years (HR 0.65, 95% CI: 0.49–0.85, P=0.001; HR 0.66, 95% CI 0.50–0.88, P=0.004, respectively); long-term SBP of <120mmHg had similar risk of mortality (HR 1.03, 95% CI: 0.78–1.36, P=0.836), compared with long-term SBP of ≥140mmHg. Findings from restricted cubic spline analysis demonstrate that there was J-shaped association between long-term SBP and all-cause mortality (P=0.02). These association was essentially unchanged in sensitivity analysis. Conclusions Among patients with HFpEF, long-term SBP showed a J-shaped pattern with all-cause mortality and a range of 120–140 mmHg was significantly associated with better outcomes. Future randomized controlled trials need to evaluate optimal long-term SBP goal in patients with HFpEF. Funding Acknowledgement Type of funding source: Foundation.

Abstract Background Activation of the inflammatory response in heart failure (HF) may initially serve as a compensatory mechanism. However, on the longer term, this physiological phenomenon can become disadvantageous. Temporal patterns of inflammatory proteins other than CRP have not yet been investigated in patients with stable HF. Purpose We aimed to evaluate the association of 17 serially measured cytokines and cytokine receptors with clinical outcome in patients with stable heart failure. Methods In 263 patients, 1984 serial, tri-monthly blood samples were collected during a median follow-up of 2.2 (IQR: 1.4–2.5) years. The primary endpoint (PE) composed of cardiovascular mortality, HF-hospitalization, heart transplantation, and LVAD. We selected baseline blood samples in all patients, as well as the two samples closest to the primary endpoint, and the last sample available in event-free patients. Thus, in 567 samples we measured 17 cytokines and cytokine receptors using the Olink Proteomics Cardiovascular III multiplex assay. Associations between biomarkers and PE were investigated by joint modelling. Results Median age was 68 (IQR: 59–76) years, with 72% men, 74% NYHA class I-II and a median ejection fraction of 30% (23–38%). 70 patients reached a PE. After adjustment for clinical characteristics (age, sex, diabetes, atrial fibrillation, NYHA class at baseline, diuretics and systolic blood pressure), 7 biomarkers were associated with the PE (Figure). Interleukin-1 receptor type 1 (IL1RT1) showed the strongest association: HR 2.65 [95% CI: 1.78–4.21]) per standard deviation change in level (NPX) at any point in time during follow-up, followed by Tumor necrosis factor receptor 1 (TNF-R1): 2.25 [1.66–3.08], and C-X-C motif chemokine 16 (CXCL16): 2.18 [1.59–3.04]. After adjustment for baseline N-terminal pro–B-type natriuretic peptide, high-sensitive troponin T and C-reactive protein however, only IL1RT1 and TNF-R1 remained significantly associated with the PE. Conclusion Repeatedly measured levels of several cytokines and cytokine receptors are independently associated with clinical outcome in stable HF patients. These results suggest that repeated measurements of these biomarkers, in addition to established cardiac biomarkers, may contribute to personalized risk assessment and herewith better identify high-risk patients.

The Impact

Background: The angiotensin receptor-neprilysin inhibitor (ARNI) decreases cardiovascular mortality in patients with chronic heart failure with a reduced ejection fraction (HFrEF). Data regarding the impact of ARNI on the outcome in HFrEF patients according to heart failure etiology are limited. Methods and results: One hundred twenty-one consecutive patients with HFrEF from the years 2016 to 2017 were included at the Medical Centre Mannheim Heidelberg University and treated with ARNI according to the current guidelines. Left ventricular ejection fraction (LVEF) was numerically improved during the treatment with ARNI in both patient groups, that with ischemic cardiomyopathy (n = 61) (ICMP), and that with non-ischemic cardiomyopathy (n = 60) (NICMP); p = 0.25. Consistent with this data, the NT-proBNP decreased in both groups, more commonly in the NICMP patient group. In addition, the glomerular filtration rate (GFR) and creatinine changed before and after the treatment with ARNI in both groups. In a one-year follow-up, the rate of ventricular tachyarrhythmias (ventricular tachycardia and ventricular fibrillation) tended to be higher in the ICMP group compared with the NICMP group (ICMP 38.71% vs. NICMP 17.24%; p = 0.07). The rate of one-year all-cause mortality was similar in both groups (ICMP 6.5% vs. NICMP 6.6%; log-rank = 0.9947). Conclusions: This study shows that, although the treatment with ARNI improves the LVEF in ICMP and NICMP patients, the risk of ventricular tachyarrhythmias remains higher in ICMP patients in comparison with NICMP patients. Renal function is improved in the NICMP group after the treatment. Long-term mortality is similar over a one-year follow-up.

Diuretic Response

Background. The diuretic response has been shown to be a robust independent marker of cardiovascular outcomes in acute heart failure patients. The objectives of this clinical research are to analyze two different formulas (diuretic response (DR) or response to diuretic (R-to-D)) in predicting 6-month clinical outcomes. Methods: Consecutive patients discharged alive after an acute decompensated heart failure (ADHF) were enrolled. All patients underwent N-terminal-pro hormone BNP (NT-proBNP) and an echocardiogram together with DR and R-to-D calculation during diuretic administration. Death by any cause, cardiac transplantation and worsening heart failure (HF) requiring readmission to hospital were considered cardiovascular events. Results: 263 patients (62% male, age 78 years) were analyzed at 6-month follow-up. During the follow-up 58 (22.05%) events were scheduled. Patients who experienced CV-event had a worse renal function (p = 0.001), a higher NT-proBNP (p = 0.001), a lower left ventricular ejection fraction (p = 0.01), DR (p = 0.02) and R-to-D (p = 0.03). Spearman rho’s correlation coefficient showed a strong direct correlation between DR and R to D in all patients (r = 0.93; p < 0.001) and both in heart failure with reduced ejection fraction (HFrEF) (r = 0.94; p < 0.001) and HF preserved ejection fraction (HFpEF) (r = 0.91; p < 0.001). At multivariate analysis, a value of R-to-D <1.69 kg/40 mg, but only <0.67 kg/40 mg for DR were significantly related to poor 6-month outcome (p = 0.04 and p = 0.05, respectively). Receiver operating characteristic (ROC) curve analyses demonstrated that DR and R-to-D are equivalent in predicting prognosis (area under curve (AUC): 0.39 and 0.40, respectively). Only R-to-D was inversely related to in-hospital stay (r = −0.23; p = 0.01). Conclusion: Adding diuresis to DR seemed to provide a better risk assessment in alive HF patients discharged after an acute decompensation.

Abstract Moderate-to-severe or severe functional mitral regurgitation (FMR) is associated with higher rates of hospitalizations and with increased mortality in heart failure with reduced left ventricular ejection fraction (HFrEF). Transcatheter mitral valve repair by MitraClip® implantation (TMVrMC) may effectively reduce severe MR, and is associated with symptomatic improvement. However, the long-term clinical effects of this procedure are not well defined. Aims We analyzed outcomes for rehospitalization and survival in heart failure patients with moderate-to-severe or severe functional mitral regurgitation (FMR) treated by either medical treatment (MT) only TMVrMC+MT by meta-analysis. Methods and results By systematic search of bibliographic databases, we evaluated publications comparing heart failure patients with FMR treated by MT only versus treatment by MT combined with TMVrMC. Studies with a minimum of 25 enrolled patients and a follow/up period of at least 12 months were deemed eligible for this meta-analysis. We identified n=7 studies enrolling 2,884 HFrEF patients, divided into two study arms: TMVrMC+MT (n=1,618), versus FMR patients receiving MT only (n=1,266). At 12 months, there was a significant reduction in all-cause mortality favoring TMVR+MT (OR: 0.67; CI 95% 0.55–0.81), as well as a reduction of unplanned rehospitalizations (OR: 0.69; 95%; CI 0.53–0.89), compared with the MT only patients. At 24 months, there was a significant reduction of all-cause mortality in the TMVrMC+MT patient group (OR: 0.50; CI: 95%: 0.38–0.66; p<0.001). TMVrMC+MT was associated with significantly lower rates of unplanned re-admissions for heart failure compared with MT only at 12 months (OR: 0.69; 95% CI: 0.53–0.89; p<0.001) and at 24 months (OR: 0.53; 95% CI: 0.39–0.71; p<0.001). In one publication, a survival benefit of TMVrMC+MT over MT alone was shown at 5 years post intervention (HR: 0.75; 95% CI: 0.69–0.94; p=0.012) after weighting for propensity score and controlling for age. Conclusions This meta-analysis on n=2,884 patients with moderate-to-severe or severe FMR reveals that TMVrMC+MT, as compared with MT alone, is associated with a significant reduction of rehospitalizations and improvement of survival. These data imply additional evidence for TMVrMC in eligible heart failure patients with relevant FMR, which might be important for an update of the corresponding guidelines.

Abstract Background Advanced glycation end-products, indicated by skin autofluorescence (SAF) levels, could be prognostic predictors of all-cause and cardiovascular mortality in patients with diabetes mellitus (DM) and renal disease. However, the clinical usefulness of SAF levels in patients with heart failure (HF) who underwent cardiac rehabilitation (CR) remains unclear. Purpose The purpose of this study was to investigate the prognostic value of SAF levels in patients with HF who underwent CR. Methods This study enrolled 204 consecutive patients with HF who had undergone CR at our university hospital between November 2015 and October 2017. Clinical characteristics and anthropometric data were collected at the beginning of CR. SAF levels were noninvasively measured with an autofluorescence reader. The major adverse cardiovascular event (MACE) was a composite of all-cause mortality and unplanned hospitalization for HF. Follow-up data concerning primary endpoints were collected until November 2018. Results Patients' mean age was 68.1 years, and 61% were males. Patients were divided into two groups according to the median SAF levels (high and low SAF groups). Patients in the high SAF group were significantly older, had a higher prevalence of chronic kidney disease, and histories of coronary artery bypass surgery; however, there were no significant between-group differences in sex, prevalence of DM, left ventricular ejection fraction, and physical function. During a median follow-up period of 623 days, 25 patients experienced all-cause mortality and 34 were hospitalized for HF. Kaplan–Meier analysis showed that patients in the high SAF group had a higher incidence of MACE (log-rank P<0.05), whereas when patients were divided into two groups according to the median hemoglobin A1c level, no significant between-group difference was observed for the incidence of MACE (Figure). After adjusting for confounding factors, Cox regression multivariate analysis revealed that SAF levels were independently associated with the incidence of MACE (hazard ratio: 1.74, 95% confidence interval: 1.12–2.65, P<0.05). Figure 1 Conclusion SAF levels were significantly associated with the incidence of MACE in patients with HF and may be useful for risk stratification in patients with HF who undergo CR.

Aims: This study assessed the impact of acute hemoglobin (Hb) falls in heart failure (HF) patients. Methods: HF patients with repeated Hb values over time were included. Falls in Hb greater than 30% were considered to represent an acute episode of anemia and the risk of hospitalization and all-cause mortality after the first episode was assessed. Results: In total, 45,437 HF patients (54.9% female, mean age 74.3 years) during a follow-up average of 2.9 years were analyzed. A total of 2892 (6.4%) patients had one episode of Hb falls, 139 (0.3%) had more than one episode, and 342 (0.8%) had concomitant acute kidney injury (AKI). Acute heart failure occurred in 4673 (10.3%) patients, representing 3.6/100 HF patients/year. The risk of hospitalization increased with one episode (Hazard Ratio = 1.30, 95% confidence interval (CI) 1.19–1.43), two or more episodes (HR = 1.59, 95% CI 1.14–2.23, and concurrent AKI (HR = 1.61, 95% CI 1.27–2.03). A total of 10,490 patients have died, representing 8.1/100 HF patients/year. The risk of mortality was HR = 2.20 (95% CI 2.06–2.35) for one episode, HR = 3.14 (95% CI 2.48–3.97) for two or more episodes, and HR = 3.20 (95% CI 2.73–3.75) with AKI. In the two or more episodes and AKI groups, Hb levels at the baseline were significantly lower (10.2–11.4 g/dL) than in the no episodes group (12.8 g/dL), and a higher and significant mortality in these subgroups was observed. Conclusions: Hb falls in heart failure patients identified those with a worse prognosis requiring a more careful evaluation and follow-up.

However, few reports discuss the difference in clinical predictors for recurrent VT/VF between patients with ischemic cardiomyopathy (ICM) and patients with dilated cardiomyopathy (DCM).MethodsFrom May 2004 to December 2015, 132 consecutive patients who had ICM (n= 94) or DCM (n= 38) and had received ICD implantation for secondary prevention were enrolled in this study. All anti-tachycardia events during follow-up were validated. The clinical characteristics and echocardiographic parameters were obtained for comparison. The incidence of recurrence of VT/VF, cardiovascular mortality, all-cause mortality, the change of left ventricular ejection fraction (LVEF) and LV volume were analyzed.ResultsAt a mean follow-up of 3.62 ± 2.93 years, 34 patients (36.2%) in the ICM group and 22 patients (57.9%) in the DCM group had a recurrence of VT/VF episodes (p= 0.032). The DCM group had a lower LVEF (p= 0.019), a larger LV end-diastolic volume (LVEDV) (p= 0.001), a higher prevalence of LVEDV >158 mL (p= 0.010), and a larger LV end-systolic volume (p= 0.010) than the ICM group. LVEDV >158 mL and no use of angiotensin-converting-enzyme inhibitor/angiotensin receptor blocker were independent predictors of recurrences of VT/VF in ICM patients but not in DCM patients. There were no difference in cardiovascular mortality and all-cause mortality between the ICM and DCM patients.ConclusionThe DCM patients had a higher recurrence rate of VT/VF than did the ICM patients during long-term follow-up. An enlarged LV is an independent predictor of the recurrence of VT/VF in ICM patients receiving ICD for secondary prevention.
