Background: Sacubitril/valsartan decreased the risk of sudden cardiac death (SCD) in patients suffering from heart failure with reduced ejection fraction (HFrEF). However, long-term data are sparse. Objective: The aim of the present study was to compare the incidence of life-threatening arrhythmias consisting of ventricular tachycardia and/or ventricular fibrillation before and after initiation of sacubitril/valsartan treatment. Methods: Out of 12,000 patients with HFrEF from 2016–2018, 148 patients were newly prescribed sacubitril/valsartan, but the long-term data of only 127 patients were available and included in this study. Results: Patients with an average age of 66.8 ± 12.1 had a median left ventricular ejection fraction (LVEF) of 25% (interquartile range (IQR) 5.00–45.00) and 30% (IQR 10.00–55.00, p < 0.0005) before and after sacubitril/valsartan treatment, respectively. Systolic blood pressure decreased from 127.93 ± 22.01 to 118.36 ± 20.55 mmHg (p = 0.0035) at 6 months of follow-up. However, in 59 patients with a long-term outcome of 12 months, ventricular arrhythmias persistently increased (ventricular fibrillation from 27.6 to 29.3%, ventricular tachycardia (VT) from 12% to 13.8%, and nonsustained VT from 26.6 to 33.3%). Conclusions: Sacubitril/valsartan does not reduce the risk of ventricular tachyarrhythmias in chronic HFrEF patients over 12 months of follow-up.

Malignant Arrhythmias

Left-ventricular non-compaction (LVNC) is a rare form of cardiomyopathy. Its clinical presentation is highly variable and during pregnancy is frequently associated with heart failure, embolic events, and arrhythmias. Herein we report a case of a woman with left ventricular non-compaction who had an automated defibrillator implantation for recurrent ventricular arrhythmias during pregnancy. During pregnancy and at long-term follow-up no interventions of the device were documented. In conclusion, the management of malignant arrhythmias during pregnancy is one of the concerns for patients with LVNC and requires a careful approach in third-level centers.

Abstract Background According to guidelines, implantable cardioverter defibrillator (ICD) is recommended in prevention of sudden cardiac death (SCD) in heart failure (HF) patients (pts). Guidelines have several limitations because ICD indication is based mainly on left ventricular ejection fraction (LVEF). Recently, 123-iodine metaiodobenzylguanidine imaging (123-I MIBG) seems to identify, independently from LVEF, pts at high risk of SCD: heart/mediastinum (H/M) ratio<1.6 and summed score (SS)>26. Purpose The aim is to assess the role of 123-I MIBG to predict malignant ventricular arrhythmias (VA) in HF pts Methods We enrolled 208 pts, admitted to our hospital with diagnosis of HF and LVEF≤35%, NYHA class II and III, who underwent 123-I MIBG imaging. H/M ratio of 1.6 was used as a cut-off to identify high risk (G1) versus low risk pts (G2). All pts underwent ICD implantation. Follow-up was performed at 24 months. Results 138 patients were included in G1 and 70 patients in G2. All baseline characteristics were similar in the two groups (table 1). At 24 months follow-up VA events were recorded greater in G1 compared to G2 (21% vs 10%, p=0.04). Table 1 G1 G2 P value H/M ≤1.6 (N=138) H/M >1.6 (N=70) Age (years) 65±12 63±14 0.28 Male, N (%) 108 (78) 64 (91) 0.02 Diabetes mellitus type II, N (%) 54 (39) 14 (20) 0.01 Dyslipidemia, N (%) 58 (42) 30 (42) 0.64 LVEF (%) 30±5 31±4 0.14 Ischaemic CM, N (%) 85 (62) 30 (42) 0.012 Malignant VA, N (%) 30 (21) 7 (10) 0.04 SS 38±9 16±7 0.0001 H/M: heart mediastinum ratio; LVEF: left ventricular ejection fraction; CM: cardiomyopathy; VA: ventricular arrhythmias; SS: summed score. Conclusion Our results seem to confirm that 123-I MIBG uptake is associated with the occurrence of life-threatening VA in HF pts independently from LVEF. The use of 123-I MIBG could be a useful tool in the future to increase the specificity of the pts selection for ICD therapy.

Our objective was to describe the long-term effects of endoscopic mitral valve (MV) repair on outcome in patients with heart failure with preserved ejection fraction (HFpEF) and atrial functional mitral regurgitation (AFMR). In patients with HFpEF, even mild AFMR has been associated with poor outcome. The study population consisted of consecutive patients with HFpEF (left ventricular ejection fraction (LVEF) ≥ 50%, H2FPEF score ≥ 5) and AFMR, who underwent isolated, minimally invasive endoscopic MV repair (MVRepair group) (n = 131) or remained on standard of care (StanCare group) (n = 139). Patients with coronary artery disease or organic mitral regurgitation (MR) were excluded. Patients were matched using inverse probability of treatment weighting. Endpoints were all-cause mortality and a composite of all-cause mortality and HFpEF readmissions. The median follow-up was 5.03 years (interquartile range (IQR) 2.6–7.9 years). In the MVRepair group, the perioperative, 30-day, 1-year, and 5-year mortality were 0, 1%, 1%, and 12%, respectively. Additionally, 13 (10%) patients were readmitted for worsening HFpEF, while 2 (1%) individuals underwent redo MV surgery for recurrent MR. MVRepair compared with StanCare showed 21–29% (Standard Error (SE) 6–8%) and 19–26% (SE 6–8%) absolute risk reduction of all-cause mortality and HFpEF readmissions, respectively (all p < 0.05). MVRepair emerged as the strongest independent predictor of all-cause mortality (Hazard Ratio (HR) 0.16, 95% (Confidence Interval (CI) 0.07–0.34, p < 0.001) and HFpEF readmissions (HR 0.21, 95% CI 0.09–0.51, p < 0.001). At 5-year follow-up, in the MVRepair group, a total of 88% were alive and 80% were alive without readmission for HFpEF. We can conclude that endoscopic MV repair is associated with low perioperative mortality as well as high long-term efficacy, and appears to improve clinical outcome in patients with AFMR and HFpEF.

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: &lt;120mmHg, ≥120mmHg and &lt;130mmHg, ≥130mmHg and &lt;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 &lt;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 &lt;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 Despite optimal medical and surgical treatment, mortality in infective endocarditis (IE) remains high. Aim of this study was to identify predictors of long term mortality for any cause, adverse event rate, relapse rate and valvular dysfunction at follow-up, in a high-volume surgical center. Methods We retrospectively analyzed 358 consecutive patients (127 women) admitted to our department with definite diagnosis of IE not device-related. IE occurred on native valves in 224 patients (63%); the infection involved the aortic valve in 192 (54%), mitral valve in 139 (39%) and tricuspid valve in 26 (7%). Overall 285 (80%) patients underwent surgery and 73 (20%) were treated conservatively, 38 due to absence of surgical indication and 35 due to refusal or prohibitive surgical risk. Long-term follow-up was obtained by structured telephone interviews. Primary endpoints were all-cause mortality, freedom from recurrent endocarditis, postoperative incidence of major adverse events (hospitalization for any cause, pace-maker implantation, new onset of atrial fibrillation, sternal dehiscence), worsening of left ventricular ejection fraction (LVEF) and valvular dysfunction. Results Mean age was 65 years (SD 15.2). Mean vegetation length was 8.9 mm (SD 7.6). Endocarditis was left-sided in 332 (93%). Average follow-up was 6 months. At univariable analysis, mortality was associated with female gender (p=0.031), age (p&lt;0.001), higher EuroSCORE 2 (p&lt;0.001), chronic renal failure (p&lt;0.001), diabetes (p=0.002), brain embolism on presentation (p=0.05), double valve infection (p=0.008), low ejection fraction (p&lt;0.001), paravalvular extension (p=0.031), prosthetic infection (p=0.018), exclusion from surgery if indicated (p&lt;0.001), high procalcitonin levels (p=0.035); factors associated with a significantly lower mortality were streptococcal infection (p=0.04; OR 0.34) and early surgery (p=0.009, OR 0.55). At multivariable analysis independent predictors of all-cause mortality were lower EF, EuroSCORE2, procalcitonin levels and diabetes. Non-fatal adverse events were associated with renal failure (p 0.035, OR 2.8). Relapse rate was associated with S aureus infection (p=0.005, OR 3.8), right-sided endocarditis (p&lt;0.001, OR 6.7) and drug abuse (p&lt;0.001, OR 9.4). Conclusions The present study shows that low EF, EuroSCORE2, procalcitonin levels and diabetes are independent predictors of death in patients with IE. Non-fatal adverse events are more frequent in patients with renal failure. Relapse rate is higher in drug abusers. These informations may help personalize follow-up strategies after acute admission for IE. Funding Acknowledgement Type of funding source: None

Neprilysin Inhibitor

The angiotensin receptor–neprilysin inhibitor (ARNI) sacubitril/valsartan and sodium-glucose cotransporter-2 (SGLT-2) inhibitor dapagliflozin have been shown to reduce rehospitalization and cardiac mortality in patients with heart failure (HF) with reduced ejection fraction (HFrEF). We aimed to compare the long-term cardiac and all-cause mortality of ARNI and dapagliflozin combination therapy against ARNI monotherapy in patients with HFrEF. This retrospective study involved 244 patients with HF with New York Heart Association (NYHA) class II–IV symptoms and ejection fraction ≤40%. The patients were divided into 2 groups: ARNI monotherapy and ARNI+dapagliflozin. Median follow-up was 2.5 (.16–3.72) years. One hundred and seventy-five (71.7%) patients were male, and the mean age was 65.9 (SD, 10.2) years. Long-term cardiac mortality rates were significantly lower in the ARNI+dapagliflozin group (7.4%) than in the ARNI monotherapy group (19.5%) ( P = .01). Dapagliflozin [Hazard Ratio (HR) [95% Confidence Interval (CI)] = .29 [.10–.77]; P = .014] and left ventricular ejection fraction (LVEF) [HR (95% CI) = .89 (.85–.93); P < .001] were found to be independent predictors of cardiac mortality. Our study showed a significant reduction in cardiac mortality with ARNI and dapagliflozin combination therapy compared with ARNI monotherapy.

Ventricular Fibrosis

Introduction: Sudden death due to ventricular arrhythmias (VA) is one of the main causes of mortality in patients with heart failure and preserved ejection fraction (HFpEF). Ventricular fibrosis in HFpEF has been suspected as a substrate of VA, but the degree of fibrosis has not been well characterized. Hypothesis: HFpEF patients with increased degree of fibrosis will manifest more VA. Methods: Cedars-Sinai medical records were probed using Deep 6 artificial intelligence data extraction software to identify patients with HFpEF who underwent cardiac magnetic resonance imaging (MRI). MRI of identified patients were reviewed to measure extra-cellular volume (ECV) and degree of fibrosis. Ambulatory ECG monitoring (Ziopatch) of those patients were also reviewed to study the prevalence of arrhythmias. Results: A total of 12 HFpEF patients who underwent cardiac MRI were identified. Patients were elderly (mean age 70.3 ± 7.1), predominantly female (83%), and overweight (mean BMI 32 ± 9). Comorbidities included hypertension (83%), dyslipidemia (75%), and coronary artery disease (67%). Mean left ventricular ejection fraction by echocardiogram was 63 ± 8.7%. QTc as measured on ECG was not significantly prolonged (432 ± 15 ms). ECV was normal in those patients for whom it was available (24.2 ± 3.1, n = 9) with 3/12 patients (25%) demonstrating ventricular fibrosis by MRI (average burden of 9.6 ± 5.9%). Ziopatch was obtained in 8/12 patients (including all 3 patients with fibrosis) and non-sustained ventricular tachycardia (NSVT) was identified in 5/8 (62.5%). One patient with NSVT and without fibrosis on MRI also had a sustained VA recorded. In those patients who had Ziopatch monitoring, there was no association between presence of fibrosis and NSVT (X2 = 0.035, p = 0.85). Conclusions: Ventricular fibrosis was present in 25% of HFpEF patients in this study and NSVT was observed in 62.5% of those patients with HFpEF who had Ziopatch monitoring. The presence of fibrosis by Cardiac MRI was not associated with NSVT in this study; however, the size of the cohort precludes broadly generalizable conclusions about this association. Further investigation is required to better understand the relationship between ventricular fibrosis by MRI and VA in patients with HFpEF.
