Abstract Background Cardiac affectation in amyloidosis is presented among 50% patients what implies worse prognostic. Early diagnosis and prognostic stratification is mandatory after the appearance of new therapies that could modify the course of the disease. Purpose The aim of our study was to assess the prognostic value of cardiac magnetic resonance parameters, including Tissue deformation, in cardiac amyloidosis patients. Methods We recruited patients (p) prospectively followed in our cardiomyopathy unit, for a mean period of 10 years (from 2010 to 2020) who were diagnosed with CA. Baseline clinical, laboratory and echocardiographic data were obtained. Contrast-enhanced CMR was performed on a 1.5 T clinical scanner. Routine analysis was performed with a semi-automatic software for volumetric analysis. When late gadolinium enhancement was present, percentage of area of enhancement (LGE) was calculated.All strain parameters were measured off-line using dedicated software. Left ventricular circumferential strain (CS) measurements were obtained using mid-ventricular level short-axis cine views. Longitudinal strain (LS) derived from cine SSFP of 2-, 3-, and 4-chamber long axis views.Finally we evaluated the CMR parameters related with the combined event of mortality and heart failure in the follow-up. Results A total of 98 p were included, with a mean age of 67.5±16.9 years old. Mean follow-up was 42,2±32 months. 22 p (24,4%) had light-chain amyloidosis (AL), 34 p (37,8%) wild type transthyretin amyloidosis (ATTRwt) and 34 p (37,8%) familiar transthyretin amyloidosis (ATTRm). 59p (60,8%) died or present heart failure during the follow-up. Patients who died or present heart failure in the follow-uo had lower left ventricular ejection fraction (48,25±12,2% vs 56,13±11,03%, p=0,003), higher myocardial mass (156,05±54,8g vs 120,84±56,1g, p=0,007), higher LGE (8,6±6,8% vs 4,4±2%), worst GLS (−14,76±6,1% vs −18,67±6,2%) and worst GCS (−23,3±9,7% vs −30,04±9,1%). Both, GLS and GCS were independently associated with the combined event of dead or heart failure when evaluated within a multivariate analysis in a Cox regression model, but GCS was the stronger predictor of events in the follow-up over other CMR parameters like LGE an myocardial mass (p<0,001). Tertile distribution for GCS identified subgroups with different adverse events, particularly for the lowest-risk tertile: GCS <−34%, who had a combinated event in 13,6% of cases, significantly lower than patients in the mid-risk tertile (41,5%) and highest-risk tertile (53,8%) (Log-rank p=0,02) Conclusion Mortality and appearance of heart failure in cardiac amyloid patients is high. The assessment of myocardial strain parameters by CMR tissue-tracking in this population is useful to predict adverse outcomes in the follow-up. Particularly, GCS, stratify patients in subgroups with different risk of events, with added value to classical CMR parameters. FUNDunding Acknowledgement Type of funding sources: None.

Abstract Background Heart failure (HF) is a major and growing medical and economic problem, with high prevalence and incidence rates worldwide. Cardiac Biomarker is emerging as a novel tool for improving management of patients with HF with a reduced left ventricular ejection fraction (HFrEF). Methods This is a before and after interventional study, that assesses the impact of a personalized follow-up procedure for HF on patient’s outcomes and care associated cost, based on a clinical model of risk stratification and personalized management according to that risk. A total of 192 patients were enrolled and studied before the intervention and again after the intervention. The primary objective was the rate of readmissions, due to a HF. Secondary outcome compared the rate of ED visits and quality of life improvement assessed by the number of patients who had reduced NYHA score. A cost-analysis was also performed on these data. Results Admission rates significantly decreased by 19.8% after the intervention (from 30.2 to 10.4), the total hospital admissions were reduced by 32 (from 78 to 46) and the total length of stay was reduced by 7 days (from 15 to 9 days). The rate of ED visits was reduced by 44% (from 64 to 20). Thirty-one percent of patients had an improved functional class score after the intervention, whereas only 7.8% got worse. The overall cost saving associated with the intervention was € 72,769 per patient (from € 201,189 to € 128,420) and €139,717.65 for the whole group over 1 year. Conclusions A personalized follow-up of HF patients led to important outcome benefits and resulted in cost savings, mainly due to the reduction of patient hospitalization readmissions and a significant reduction of care-associated costs, suggesting that greater attention should be given to this high-risk cohort to minimize the risk of hospitalization readmissions.

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.

Background . The use of implantable cardiac defibrillators has been associated with improved survival in several well-defined patient (pt) subsets. Its utilization for primary prevention in eligible pts, however, is unclear. We sought to examine the frequency of ICD implantation (ICD-IMP) for primary prevention in a cohort prospectively enrolled in a prospective, multicenter registry of ICD candidates. Methods . We identified 961 pts enrolled in the AdreView Myocardial Imaging for Risk Evaluation in Heart Failure (ADMIRE-HF) study, a prospective, multicenter study evaluating the prognostic usefulness of 123I-mIBG scintigraphy in a heart failure population. Inclusion criteria limited patients to those meeting guideline criteria for ICD implantation; these criteria included left ventricular ejection fraction ≤35% and New York Heart Association functional class II-III. We excluded pts with an ICD at the time of enrollment, leaving a study cohort of 934 patients. Pts were followed up for 24 months after enrollment. Pts undergoing ICD-IMP after enrollment for secondary prevention were censored at the time of intervention. The association between ICD-IMP utilization and demographic, clinical, laboratory, and imaging data was examined using Cox proportional hazards analysis (CPH). Results . Of 934 pts, 196 (21%) were referred for ICD-IMP over a mean follow-up of 612±242 days. Implantations occurred 167±164 days after enrollment. Patients referred for ICD were younger (61±12 vs. 63±12), but did not differ with respect to proportion female (17% vs. 21%), African-American race (12% vs. 15%), diabetics (37% vs. 36%) (All p=NS). The frequency of ICD-IMP did not differ as a function of age, race, sex, LVEF, or imaging result (All p=NS). CPH revealed that a model including age, race, sex, diabetes, smoking, BMI, NYHA class, hypertension, heart failure etiology, and prior MI identified none of these as predictive of ICD-IMP. Conclusion: This analysis of prospective registry data reveals that in patients who are guideline-defined candidates for ICD-IMP, only about one in five receive an ICD over a two year follow-up interval. Multivariable modeling failed to identify any factor associated with ICD use.

Background: BNP testing is now common though it is not clear if the test results are used to improve patient care. A high BNP may be an indicator that the left ventricular ejection fraction (LVEF) is low (<40%) such that the patient will benefit from life-prolonging therapy. Objective: To determine how often clinicians obtained a measure of LVEF (echocardiography, nuclear) following a high BNP value when the left ventricular ejection fraction (LVEF) was not known to be low (<40%). Methods and Results: We reviewed the medical records of 296 consecutive patients (inpatient or outpatient) with a BNP values of at least 200 pg/ml at a single medical center (tertiary hospital with 8 community clinics). A prior diagnosis of heart failure was made in 65%, while 42% had diabetes, 79% had hypertension, 59% had ischemic heart disease and 31% had chronic lung disease. The mean age was 73 ± 12 years, 75% were white, 10% black, 15% other and the mean BNP was 810 ± 814 pg/ml. The LVEF was known to be < 40% in 84 patients (28%, mean BNP value of 1094 ± 969 pg/ml). Of the remaining 212 patients without a known low LVEF, 161 (76%) had a prior LVEF >=40% ( mean BNP value of 673 ± 635 pg/ml), and 51 (24%) had no prior LVEF documented (mean BNP 775 ± 926 pg/ml). Following the high BNP, a measure of LVEF was obtained (including outside studies documented by the primary care provider) within 6 months in only 53% (113 of 212) of those with an LVEF not known to be low. Of those with a follow-up echocardiogram, the LVEF was <40% in 18/113 (16%) and >=40% in 95/113 (84%). There was no significant difference in mean initial BNP values between those with a follow-up LVEF <40% (872 ± 940pg/ml), >=40% (704 ± 737 pg/ml), or not done (661 ± 649 pg/ml, p=0.5). Conclusions: Follow-up measures of LVEF did not occur in almost 50% of patients with a high BNP where the information may have led to institution of life-prolonging therapy. Of those that did have a follow-up study a new diagnosis of depressesd LVEF was noted in 16%. Screening of existing BNP and LVEF data and may be an efficient strategy to identify patients that may benefit from life-prolonging therapy for heart failure.

Background: Cardiopulmonary exercise test (CPET) is a crucial tool for the functional evaluation of cardiac patients. We hypothesized that VO2 max and VE/VCO2 slope are not the only parameters of CPET able to predict major cardiac events (mortality or cardiac transplantation urgently or elective). Objectives: We aimed to identify the best CPET predictors of major cardiac events in patients with severe chronic heart failure and to propose an integrated score that could be applied for their prognostic evaluation. Methods: We evaluated 140 patients with chronic heart failure who underwent CPET between 2011 and 2019. Major cardiac events were evaluated during follow-up. Univariate and multivariate logistic regression analysis were applied to study the predictive value of different clinical, echocardiographic and CPET parameters in relation to the major cardiac events. A score was generated and c-statistic was used for the comparisons. Results: Thirty-nine patients (27.9%) died or underwent cardiac transplantation over a median follow-up of 48 months. Five parameters (maximal workload, breathing reserve, left ventricular ejection fraction, diastolic dysfunction and non-idiopathic cardiomyopathy) were used to generate a risk score that had better risk discrimination than NYHA dyspnea scale, VO2 max, VE/VCO2 slope > 35 alone, and combined VO2 max and VE/VCO2 slope (p= 0.009, 0.004, < 0.001 and 0.005 respectively) in predicting major cardiac events. Conclusions: A composite score of CPET and clinical/echocardiographic data is more reliable than the single use of VO2max or combined with VE/VCO2 slope to predict major cardiac events.

Introduction: MPI is an echocardiographic parameter that exibit the left ventricular functions globally. NT-proBNP  is an important both diagnostic and prognostic factor in heart failure. In this study, we aimed to investigate the prognostic significance of serum NT-proBNP levels and MPI in patients with STEMI. Method: Totally 104 patients with a diagnosis of STEMI were included in the study. Patients followed for 30-days and questioned for presence of symptoms of heart failure (HF) and cardiac death. Patients were invited for outpatient control after 30-days and were divided into two groups: (HF (+) group) and (HF (-) group). Results: Totally 104 patients with STEMI were hospitalized in the coronary intensive care unit. Of those patients, 17 were female (16%), 87 were male (84%), and the mean age of the patients was 58.9±10.8 years. During the 30-day follow-up, 28 (27%) of 104 patients developed HF. The mean age, hypertension ratio and anterior STEMI rate were significantly higher in the HF (+) group compared to the HF (-) group. Ejection time (ET) and left ventricular ejection fraction (LVEF) were significantly lower and MPI was significantly higher in the HF (+) group. When the values on day first and  sixth were compared, NT-ProBNP levels were decreased in both groups. There was no significant difference between the two groups in terms of the change in MPI values on the first and sixth days. Multiple regression analysis showed that the presence of anterior MI, first day NT-proBNP level and LVEF were independently associated with development of HF and death. Conclusion: In our study, NT-proBNP levels were found to be positively associated with MPI in patients with acute STEMI. It was concluded that the level of NT-proBNP detected especially on the 1st day was more valuable than MPI in determining HF development and prognosis after STEMI.

Background: A significant number of heart failure (HF) patients with reduced left ventricular ejection fraction (LVEF) experience ventricular function recovery during follow-up. We studied the variables associated with LVEF recovery in patients treated with sacubitril/valsartan (SV) in clinical practice. Methods: We analyzed data from a prospective and multicenter registry including 249 HF outpatients with reduced LVEF who started SV between October 2016 and March 2017. The patients were classified into 2 groups according to LVEF at the end of follow-up (>35%: group R, or ≤35%: group NR). Results: After a mean follow-up of 7 ± 0.1 months, 62 patients (24.8%) had LVEF >35%. They were older (71.3 ± 10.8 vs. 67.5 ± 12.1 years, p = 0.025), and suffered more often from hypertension (83.9 vs. 73.8%, p = 0.096) and higher blood pressure before and after SV (both, p < 0.01). They took more often high doses of beta-blockers (30.6 vs. 27.8%, p = 0.002), with a smaller proportion undergoing cardiac resynchronization therapy (14.8 vs. 29.0%, p = 0.028) and fewer implanted cardioverter defibrillators (ICD; 32.8 vs. 67.9%, p < 0.001), this being the only predictive variable of NR in the multivariate analysis (OR 0.26, 95% CI 0.13–0.47, p < 0.0001). At the end of follow-up, the mean LVEF in group R was 41.9 ± 8.1% (vs. 26.3 ± 4.7% in group NR, p < 0.001), with an improvement compared with the initial LVEF of 14.6 ± 10.8% (vs. 0.8 ± 4.5% in group NR, p < 0.0001). Functional class improved in both groups, mainly in group R (p = 0.035), with fewer visits to the emergency department (11.5 vs. 21.6%, p = 0.07). Conclusions: In patients with LVEF ≤35% treated with SV, not carrying an ICD was independently associated with LVEF recovery, which was related to greater improvement in functional class.

AbstractFew reports have discussed appropriate strategies for patient referrals to advanced heart failure (HF) centers with available left ventricular assist devices (LVADs). We examined the association between the characteristics and prognoses of referred patients with advanced HF and the bed volume of the referring hospitals. This retrospective analysis evaluated 186 patients with advanced HF referred to our center for consultation about the indication of LVAD between January 1, 2015, and August 31, 2018. We divided the patients into two groups according to the bed volume of their referring hospital (high bed volume hospitals (HBHs): ≥ 500 beds in the hospital; low bed volume hospitals (LBHs): < 500 beds). We compared the primary outcome measure, a composite of LVAD implantation and all-cause death, between the patients referred from HBHs and patients referred from LBHs. The 186 patients with advanced HF referred to our hospital, who were referred from 130 hospitals (87 from LBHs and 99 from HBHs), had a mean age of 43.0 ± 12.6 years and a median left ventricular ejection fraction of 22% [15–33%]. The median follow-up duration of the patients was 583 days (119–965 days), and the primary outcome occurred during follow-up in 42 patients (43%) in the HBH group and 20 patients (23%) in the LBH group. Patients referred from HBHs tended to require catecholamine infusion on transfer more often than those referred from LBLs (36.5% (HBH), 20.2% (LBL), P = 0.021). Kaplan–Meier analysis indicates that the occurrence of the primary outcome was significantly higher in the HBH patients than in the LBH patients (log-rank P = 0.0022). Multivariate Cox proportional hazards analysis revealed that catecholamine support on transfer and long disease duration were statistically significant predictors of the primary outcome. Patients from HBHs had a greater risk of the primary outcome. However, the multivariate analysis did not indicate an association between referral from an HBH and the primary outcome. In contrast, catecholamine support on transfer, long duration of disease, and low blood pressure were independent predictors of the primary outcome. Therefore, these should be considered when determining the timing of a referral to an advanced HF center, irrespective of the bed volume of the referring hospital.

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 BACKGROUND New echocardiographic phenotypes of heart failure (HF) are focused on myocardial systolic involvement of the left ventricle (LV), either endocardial and/or transmural. PURPOSE. To study the pattern of myocardial involvement in patients (p) with HF with preserved left ventricular ejection fraction (pLVEF) and cardiac amyloidosis (CA). METHODS. Comparative study of 16 p with CA and HF with pLVEF, considering as cut point LVEF &gt; 50%, in NYHA class ≥ II / IV, and a control group of 16 healthy people. Longitudinal Strain (LS) and Circumferential Strain (CS) were calculated using 2D speckle-tracking echocardiography, along with Mitral Annulus Plane Systolic Excursion (MAPSE) and Base-Apex distance (B-A). Also, the following indexes were calculated: Twist (apical rotation + basal rotation, º); Classic Torsion (TorC): (twist/B-A, º/cm); Torsion Index (Tor.I): (twist/MAPSE, º/cm) and Deformation Index (Def.I): (twist/LS, º). We suggest the introduction of these dynamic torsion indexes as Tor.I and Def.I that include twist per unit of longitudinal systolic shortening of the LV instead of using TorC which is the normalisation of twist to the end-diastolic longitudinal diameter of the LV. RESULTS There were no differences of age between the groups (68.2 ± 11.5 vs 63.7 ± 2.8 years, p = 0.14). Global values of LS and CS were lower in p with CA indicating endocardial and transmural deterioration during systole, while TorC and Twist of the LV remained conserved in p with CA. However, there is an increase of dynamic torsion parameters such as Tor.I and Def.I that show an increased Twist per unit of longitudinal shortening of the LV in the CA group (Table). CONCLUSIONS In p with CA and HF with pLVEF, the impairment of LS and CS indicates endocardial and transmural systolic dysfunction. In these conditions, LVEF would be preserved at the expense of a greater dynamic torsion of the LV. Table LS (%) CS (%) Twist (º) TorC (º/cm) Tor.I (º/cm) Def.I (º/%) CA pLVEF (n = 16) -11.7 ± 4.2 17.2 ± 4.8 19.8 ± 8.3 2.5 ± 1.1 27.7 ± 13.5 -1.8 ± 0.9 Control Group (n = 15) -20.6 ± 2.5 22.7 ± 4.9 21.7 ± 6.1 2.7 ± 0.8 16.4 ± 4.7 -1.0 ± 0.3 p &lt; 0.001 &lt; 0.01 0.46 0.46 &lt; 0.01 &lt; 0.01 Dynamic Torsion Indexes and Classic Torion Parameters in pLVEF CA patients vs Control group.
