Heart Failure Improvement after Autologous Bone Marrow Mononuclear Cells (ABMMC) Transplantation.

Abstract Background: Pilot studies suggest that intracoronary transplantation of unselected ABMMC cells may improve Left Ventricular Ejection Fraction (LVEF) in heart failure (HF) Methods: 18 patients were enrolled and completed 1 year follow up. Patients underwent SPECT evaluation, all had ejection fraction < 35%, 6 patients were randomly allocated to the control group and 12 in the Bone Marrow Cells (BMC) group, median age 65 years old, male/female ratio 17/1; all with ischemic cardiomyopathy. All of cohort had NYHA class of III with maximal medical therapy and median basal LEVF was 28.38% (SD=6.5%). Median number of mononuclear and CD34+ cells infused were 8.1*108 and 1.2*107 respectively in a 50 cc delivered retrograde via coronary sinus approach using balloon occlusion "over wire" for 8 to 10 minutes. No study related adverse events were observed. Results: After a median time of 21 days, patients in the BMC group had relief of dyspnea symptoms and improvement in functional class. At 1 year, NYHA class improved in 92% of the patients in the BMC group by at least 1 class and no improvement in the control group. Mean improvements of LVEF post BMC transplantation were 6.18% (SD=4.94%) and 6.7% (SD=4.07%) at rest and stress SPECT respectively. Rest LVEF at baseline and after one-year follow up between the BMC and control groups demonstrates significant difference (4.9% vs 1.6%, p=0.006), as well as the comparison of change in stress LVEF in both groups (6.7% vs 0.11%, p<0.001). Conclusions: Infusion of progenitor cells into the coronary sinus is safe and feasible in the ischemic HF. It is associated with significant improvement in symptoms, functional capacity and LVEF. Larger randomized studies are in progress to build upon this pilot study. Figure Figure

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.

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 > 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 < 0.001 < 0.01 0.46 0.46 < 0.01 < 0.01 Dynamic Torsion Indexes and Classic Torion Parameters in pLVEF CA patients vs Control group.

The Impact

Abstract Aims Current guidelines recommend an implantable cardiac defibrillator (ICD) in patients with symptomatic heart failure and reduced ejection fraction [HFrEF; left ventricular ejection fraction (LVEF) ≤35%] despite ≥3 months of optimal medical therapy. Recent observations demonstrated that sacubitril/valsartan induces beneficial reverse cardiac remodelling in eligible HFrEF patients. Given the pivotal role of LVEF in the selection of ICD candidates, we sought to assess the impact of sacubitril/valsartan on ICD eligibility and its predictors in HFrEF patients. Methods and results We retrospectively evaluated 48 chronic HFrEF patients receiving sacubitril/valsartan and previously implanted with an ICD in primary prevention. We assumed that ICD was no longer necessary if LVEF improved >35% (or > 30% in asymptomatics) at follow-up. Over a median follow-up of 11 months, sacubitril/valsartan induced a significant drop in LV end-systolic volume (−16.7 ml/m2, P = 0.023) and diameter (−6.8 mm, P = 0.022), resulting in a significant increase in LVEF (+3.9%, P < 0.001). As a consequence, 40% of previously implanted patients resulted no more eligible for ICD at follow-up. NYHA class improved in the 50% of population. A dose-dependent effect was noted, with higher doses associated to more reverse remodelling. Among patients deemed no more eligible for ICD, lower NYHA class [odds ratio (OR): 3.73 (95% CI: 1.05–13.24), P = 0.041], better LVEF [OR: 1.23 (95% CI: 1.01–1.48), P = 0.032], and the treatment with the intermediate or high dose of sacubitril/valsartan [OR: 5.60 (1.15–27.1), P = 0.032] were the most important predictors of status change. Conclusions In symptomatic HFrEF patients, sacubitril/valsartan induced beneficial cardiac reverse remodelling and improved NYHA class. These effects resulted in a significant reduction of patients deemed eligible for ICD in primary prevention.

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.

Abstract Ischemic heart disease is a major causes of heart failure. Heart failure patients have predominantly left ventricular dysfunction (systolic or diastolic dysfunction, or both). Acute heart failure is most commonly caused by reduced myocardial contractility, and increased LV stiffness. We performed echocardiography and gated SPECT with Tc99m MIBI within 263 patients and 166 normal individuals. Left ventricular end systolic volume (LVESV), left ventricular end diastolic volume (LVEDV), and left ventricular ejection fraction (LVEF) were measured. For all degrees of ischemia, there was a significant difference between ejection fraction values measured by SPECT and echocardiography, and there were no significant differences among end systolic volume and end diastolic volume value calculated by two methods for all cases. The mean value for EDV (ECHO)/EDV (SPECT) was 1.07 ± 0.31 for degree (1, 2); in the degree 3 the mean value was 1.02 ± 0.08, and 1.005 ± 0.07 for degree 4. The mean value for ESV (ECHO)/ESV (SPECT) was 1.08 ± 0.34 for degree (1, 2); while 1.03 ± 0.12, 1.021 ± 0.128 for degree 3 and 4 respectively. This study was showed a good relation between left ventricular size and ejection fraction measured by SPECT with Tc99m, and echocardiography.

Objective: to evaluate vasopressin (VP) concentration in patients with varying severity of chronic heart failure (CHF), intensity of clinical symptoms, and decreased level of left ventricular ejection fraction (LVEF). Materials and methods. In total, 120 patients (44 males, 76 females) with CHF of varying genesis (mean age 72.12 ± 10.18 years) and 30 clinically healthy individuals (18 males, 12 females) as a control group (mean age 33.4 ± 6.23 years) were examined. All patients underwent comprehensive clinical and instrumental examination in accordance with the standards for patients with CHF. The VP level was determined using ELISA. Statistical analysis was performed using the IBM SPSS Statistics v. 23 software.Results. The patients with CHF had significantly higher blood VP levels compared to the control group (72.91 ± 53.9 pg/ml versus 6.6 ± 3.2 pg/ml respectively; p <0.01). At the same time, patients with stage III CHF had significantly lower VP levels than patients with stages IIВ and IIА (35.61 ± 21.53 pg/ml versus 71.67 ± 48.31 pg/ml and 86.73 ± 59.78 pg/ml respectively; p<0.01). A similar picture was observed for the functional classes (FC). For instance, for CHF FC II and III, the VP level was 91.93 ± 67.13 pg/ml and 77.95 ± 54.01 pg/ml respectively, while for FC IV it decreased to 50.49 ± 28.18 pg/ml (p <0.01). The VP concentration in patients who subsequently perished was significantly lower than in patients who survived (48.79 ± 26.30 pg/ml versus 79.72 ± 57.73 pg/ml; p = 0.012). Moreover, in patients with LVEF <50 %, the VP level was significantly lower than in patients with LVEF >50 % (59.43 ± 42.51 pg/ml versus 86.43 ± 62.46 pg/ml respectively; p <0.05).Conclusion. The observed significant differences in VP in patients with stage III and IV CFH can indicate depletion of neurohumoral mediators in this patient category. However, a correlation between the VP level and the level of LVEF decrease can indicate a significant difference in the role of VP in CHF pathogenesis in patients with preserved and decreased LVEF. This observation requires further research.

Background: Relatively high left ventricular ejection fraction (EF) (>65%) in women was recently associated with higher all-cause mortality over 6 years follow-up in the CONFIRM study. We sought to evaluate high EF and major adverse cardiovascular events (MACE) in the Women’s Ischemia Syndrome Evaluation (WISE) study. Methods: The WISE original cohort (enrolled 1996-2000) is a multicenter prospective study of women with suspected ischemic heart disease undergoing clinically indicated invasive coronary angiography. We investigated the relationship between high (>65%) and normal (55-65%) EF and MACE, defined as all-cause death, nonfatal myocardial infarction (MI), stroke and heart failure (HF) hospitalization using Kaplan Meier (KM) and regression analyses. Results: A total of 653 women were included (298 high and 355 normal EF). Mean age was 58±11 years and mean EF was 68±7%. There was no significant difference in MACE by EF group over a 10-year follow-up period (log rank p=0.54, Figure ). When patients were stratified by the presence of obstructive CAD, MACE rates remained similar between high and normal EF. High EF was not associated with stroke or HF but had a lower MI risk (log rank p=0.03, Table ). EF was not associated with MACE in a multivariable regression model. Conclusions: Among women presenting with evidence of ischemia, there was no significant difference in MACE between high and normal EF groups. High EF was associated with a lower risk of myocardial infarction as an individual component of MACE.

The Relationship

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.

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.
