Abstract Introduction The impact of therapeutic hypothermia on kidneys in cardiac arrest survivors with known congestive heart failure (CHF) is not known. Weak evidence suggests higher risk of acute kidney injury with hypothermia. Purpose The effect of hypothermia on organ function in cardiac arrest patients with preexisting CHF Methods This analysis includes 1417 comatose cardiac arrest survivors that achieved achieved return of spontaneous circulation on hospitalization and had a previous left ventricular ejection fraction (LVEF) assessment within last 1 year. Detailed chart review of these patients was performed. CHF was defined as either prior episode of congestive heart failure or presence of LVEF <50%. Odds ratio (OR) and 95% confidence intervals (CI) for association of hypothermia and acute kidney injury as well as hemodialysis at discharge among patients with and without CHF were computed using multivariable adjusted logistic regression. Results Overall, 1417 cardiac arrest patients (mean age 62.5±14.6 years, 60.2% males, 67.2% white and 29.7% black) were included in this analysis, out of which 467 (33.0%) were treated with therapeutic hypothermia and known CHF was present in 624 (44%). AKI developed in 25.2% of CHF patients that were not treated with hypothermia while, only in 18.0% among CHF patients treated with hypothermia (OR 0.56; 95% CI 0.32–0.96, p=0.03). There was an decrease in trend of requiring hemodialysis at discharge among CHF patients treated with hypothermia compared with CHF patients that were not treated with hypothermia (8.1% vs. 19.62%, p=0.019) among CHF patients not treated with hypothermia. However, there was no significant result. Conclusions Hypothermia is associated with nephroprotective effects among patients with cardiac survivors with pre-existing CHF. Future research is needed to identify subgroups that derive benefit from therapeutic hypothermia after cardiac arrest.

Abstract Background Several studies suggest that psychological factors including anxiety are associated with negative outcomes and in particular higher mortality rates among congestive heart failure (CHF) patients. However, the impact of anxiety on mortality in patients with implanted cardiac devices has not been fully appreciated. Purpose To estimate the influence of anxiety on all-cause mortality in patients with CHF after implantation of cardiac electronic devices. Methods The study enrolled 268 patients (mean age 57.1±10.1 years, 218 men and 50 women) with CHF and implanted cardiac devices (170 patients with implanted cardiac devices for resynchronization therapy, 98 patients - with implantable cardioverter defibrillators). We measured symptoms of anxiety with the Spielberger State-Trait Anxiety Inventory (STAI) scale. Cox proportional hazards regression model was used to estimate hazard ratios (HR) with 95% confidence interval (95% CI) for impact of anxiety symptoms on all-cause mortality. HR was calculated after adjustment for the following confounders: age, gender, smoking status, hypertension, diabetes mellitus, body mass index, hypercholesterolemia, atrial fibrillation, left ventricular ejection fraction, number of hemodynamically significant lesions of the coronary arteries and the type of the implanted cardiac devices. Results According to State-A scale 119 (44.4%) patients had light symptoms of state anxiety (SA), 115 (42.9%) – mild SA symptoms and 34 (12.7%) – expressed SA symptoms. According to Trait-A scale 10 (3.7%) patients had light trait anxiety (TA) symptoms, 99 (40.0%) – mild TA symptoms and 159 (59.3%) – expressed TA symptoms. During prospective observation period, 46 (17.2%) patients died of all-causes. Multivariant analysis in patients with the expressed SA symptoms resulted in mortality HR which complied 5.26, 95% CI 1.99–13.90; patients with the expressed TA symptoms – 3.5, 95% CI 1.48–6.29. Conclusion SA and TA have significant and independent influence on all-cause mortality in patients with CHF after implantation of cardiac electronic devices.

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.

Introduction The impact of preserved and reduced left ventricular ejection fraction (LVEF) has been well studied in heart failure, but not in hypertension. We aimed to highlight the prevalence, clinical characteristics, comorbidities and outcomes of hospitalized hypertensives with preserved and reduced LVEF from three teaching hospitals in Nigeria. Methods: This is a retrospective study of hypertensives admitted in 2013 in three teaching hospitals in Lagos, Kano and Ogbomosho, who had echocardiography done while on admission. Medical records and echocardiography parameters of the patients were retrieved and analyzed. Results: 54 admitted hypertensive patients who had echocardiography were recruited, of which 30 (55.6%) had reduced left ventricular ejection fraction (RLVEF), defined as ejection fraction <50%; while 24 (44.4%) had preserved left ventricular ejection fraction (PLVEF). There were 37(61.5%) females and 17 (31.5%) males. Of the male patients 64.7% had RLVEF, while 35.3% had PLVEF. 19(51.4%) of females had RLVEF, while 48.6% had PLVEF. Mean age of patients with PLVEF was 58.83±12.09 vs 54.83± 18.78 of RLVEF; p-0.19. Commonest comorbidity was Heart failure (HF) followed by stroke (found among 59.3% and 27.8% of patients respectively). RLVEF was significantly commoner than PLVEF in HF patients (68.8% vs 31.3%; p- 0.019); no significant difference in stroke patients (46.7% vs 53.3%; p-0.44). Mortality occurred in 1 (1.85%) patient who had RLVEF.         Conclusion: RLVEF was more common than PLVEF among admitted hypertensive patients; they also have more comorbidities. In-hospital mortality is, however, very low in both groups.

Background: Acute kidney injury (AKI) detected after admission to coronary care unit (CCU) is associated with very poor outcomes. We prospectively investigated the prognostic value of a combination of AKI and high plasma D-dimer levels for 1-year mortality in patients hospitalized to CCUs. Methods: D-dimer, N-terminal pro-B-type natriuretic peptide (NT-proBNP), and high-sensitive C-reactive protein (hsCRP) levels were measured in 1228 patients on admission to CCUs, of whom 56% had decompensated heart failure and 38% had acute coronary syndrome. AKI was defined as an increase of >25% in creatinine from baseline or an absolute increase of ≥0.5 mg/dL within 48 h after admission. Left ventricular ejection fraction (LVEF) and E/e’ ratio were estimated using echocardiography with tissue Doppler imaging. Results: AKI was detected in 163 (13%) patients. During 1-year follow-up period, there were 149 (12%) deaths. The patients who died were older (median: 77 vs. 73 years; p < 0.0001) and exhibited higher D-dimer (2.7 vs. 1.3 μg/mL; p < 0.0001), NT-proBNP (5495 vs. 1525 pg/mL; p < 0.0001), and hsCRP levels (0.92 vs, 0.26 mg/L; p < 0.0001) and E/e’ ratio (15.0 vs. 13.2; p = 0.006). They also had a higher incidence of AKI (26% vs. 12%; p < 0.0001) and lower LVEF (39% vs. 49%; p < 0.0001) and estimated glomerular filtration rate (45 vs. 62 mL/min/1.73 m 2 ; p < 0.0001) than patients who survived. Multivariate Cox regression analysis, including 12 clinical, biochemical, and echocardiographic variables, identified AKI (relative risk: 1.79; p = 0.008) and increased D-dimer level (relative risk: 1.83 per 10-fold increment; p = 0.002) as independent predictors of 1-yeart mortality. The combined assessment of AKI and D-dimer quartiles was significantly associated with 1-year mortality rates (Figure). Conclusions: The combined assessment of AKI and high D-dimer levels may be useful for evaluating the risk of 1-year mortality in patients admitted to CCUs.

The treatment with sacubitril/valsartan in patients suffering from chronic heart failure with reduced ejection fraction increases left ventricular ejection fraction and decreases the risk of sudden cardiac death. We conducted a retrospective analysis regarding the impact of age differences on the treatment outcome of sacubitril/valsartan in patients with chronic heart failure with reduced ejection fraction. Patients were defined as adults if ≤65 years (n = 51) and older if >65 years of age (n = 76). The incidence of ventricular arrhythmias at 1-year follow-up was comparable in both groups (30.8 vs 26.5%; p = 0.71). The mortality rate in adult patients is significantly lower as compared with older patients (2 vs 14.5%; log-rank = 0.04). Older patients may suffer remarkably more side effects than adult patients (21.1 vs 11.8%; p = 0.03).

Abstract Background and purpose Post-angiography renal replacement therapy (RRT) has shown protective effects from Ci-AKI (contrast induced acute kidney injury) in patients with pre-existing advanced renal disfunction. We analysed a series of 1095 continuative patients who undergone coronary or peripheral angiography in our center. In non-haemodialyzed patients with eGFR &lt;20ml/min/1.73m2 or with poor renal reserve we performed an “early” RRT, starting during angiography procedure and applied for at least 6 h after procedure, thus diverging from previous literature data based only on post-procedure hours delayed RRT application. The RRT modality chosen was CVVHDF (continous veno-venous hemodiafiltration). Methods We considered following subjects variability: age, sex, weight, presence of hypertension, dyslipidaemia, diabetes, smoking habitude, left ventricular ejection fraction, amount of contrast media given and shock or infection occurrence during hospital stay. We evaluate statistic significative of serum creatine (SCr) variation in patients receiving RRT from pre-procedure time (T0), at 24h (T1), 48h (T2), 72h (T3) after procedure and at 3–8 weeks follow-up (T4). Quantitative data were compared with Student T test, qualitative data with Chi Square test, considering statistically significant p value &lt;0.05 with two tails. Ci-AKI was defined as serum creatinine rise ≥0.3 mg/dL at 48h from contrast media administration, following KDIGO (kidney disease improving global outcomes) guidelines definition. Results 26 patients received RRT. Medium SCr at T0 was 3.37 mg/dl and showed a significative reduction (see figure) at T1 (−0.88mg/dl = −20.6%, p=0.003) and T2 (−0.96mg/dl = −18.33%, p=0.029) and a trend towards reduction at T3 (−0.78mg/dl, p=0.174) and at T4 (−0.28mg/dl, p=0.568). Between 26 pts, 6 pts (23%) developed Ci-AKI. Only contrast media amount significatively diverge between two groups (183 ml in the group with Ci-AKI vs 162 ml in pts with no Ci-AKI, p=0.03), showing also a trend towards significance for infection occurrence (83.3% pts Ci-AKI vs 40% pts no Ci-AKI, p=0.06) and shock onset (33.3%pts Ci-AKI vs 5% pts no Ci-AKI, p=0.06). Average SCr diverge at T2 (3.18mg/dl Ci-AKI vs 2.04mg/dl no Ci-AKI, p=0.01) and at T3 (3.33mg/dl CI-AKI vs 2.31mg/dl no CI-AKI, p=0.06); we also found a trend towards progressive increase of SCr for Ci-AKI pts (T0-T1: +0.17mg/dl, p=ns; T0-T2: +0.41mg/dl, p=ns; T0-T3: +0.57mg/dl, p=ns; T0-T4: +1.35mg/dl, p=ns) and a significative reduction in SCr for no Ci-AKI pts (T0-T1: −1.23mg/dl = −29.32% p=0.001; T0-T2: −1.46mg/dl = −30.78%, p=0.01; T0-T4: −0.41mg/dl = −15.5%, p=0.05). Conclusions Early RRT with CVVHDF modality results effective in 77% of patients in avoiding Ci-AKI, with a significative SCr reduction at 24 and 48h. An increased amount of contrast media is significatively related to Ci-AKI incidence. Ci-AKI development could also possibly be related to shock and infection occurrence.
