Direct oral anticoagulants in patients with nonvalvular atrial fibrillation and extreme body weight.

BACKGROUND: Limited clinical data exist describing the use of direct oral anticoagulants (DOACs) in patient with extreme body weight. Thus, the International Society of Thrombosis and Haemostasis (ISTH) recommends avoiding DOACs in patients with weight >120 Kg, and on the contrary, no restrictions exist for underweight patients. OBJECTIVE: To evaluate the effects of extreme body weight on DOAC activity and to compare the clinical outcomes of patients with an extreme body weight versus patients with a normal weight (61-119 Kg) treated with DOACs. METHODS: Single tertiary care Italian centre multidisciplinary registry including nonvalvular atrial fibrillation (NVAF) patients treated with DOACs. Based on weight, three subcohorts were defined: (i) underweight patients (≤60 Kg); (ii) patients with a normal weight (61-119 Kg, as control group); and (iii) overweight patients (≥120 Kg). Primary efficacy endpoint was 2-year rate of thromboembolic events. Primary safety endpoint was 2-year rate of major bleeding. Event-free survival curves among groups were compared using Cox-Mantel test. RESULTS: 812 NVAF patients were included, 108 patients weighed ≤60 Kg (13%, underweight), 688 weighed between 61 and 119 Kg (85%, normal weight), and 16 weighed ≥120 Kg (2%, overweight). In particular, among underweight patients, dabigatran was prescribed in 26% patients, apixaban in 27%, rivaroxaban in 28% and edoxaban in 22% ones. Instead, among overweight patients, 44% were treated with dabigatran, 25% with apixaban, 25% with rivaroxaban and 4% with edoxaban. Underweight patients were older, more frequently women, with lower creatinine clearance and a history of previous strokes, resulting in higher CHA2DS2-VASc score than in both remaining groups. Up to 2 years, no statistically significant difference was observed between the three groups of weight for thromboembolic events (P = .765) and for overall bleeding (P = .125), but a trend towards decreased overall bleeding rates was noticed as weight increased (24.1% vs 16.7% vs 12.5%, respectively). CONCLUSION: In this tertiary care centre registry, 15% of patients treated with DOACs presented an extreme weight. Compared to patients with a normal weight, no significant rates of thromboembolic events were observed for underweight or overweight patients. A trend towards decreased overall bleeding frequency as weight increased was highlighted up to 2 years. The present results should be considered as preliminary and hypothesis generating.

Myocardial injury in patients with SARS-CoV-2 pneumonia: Pivotal role of inflammation in COVID-19.

AIMS: Infection by SARS-CoV-2 may result in a systemic disease and a proportion of patients ranging 15%-44% experienced cardiac injury (CI) diagnosed by abnormal troponin levels. The aim of the present study was to analyse the clinical characteristics of a large series of hospitalized patients for COVID-19 in order to identify predisposing and/or protective factors of CI and the outcome. METHODS AND RESULTS: This is an observational, retrospective study on patients hospitalized in two Italian centres (San Raffaele Hospital and Cremona Hospital) for COVID-19 and at least one high-sensitivity cardiac troponin (hs-cTnt) measurement during hospitalization. CI was defined if at least one hs-cTnt value was above the 99th percentile. The primary end-point was the occurrence of CI during hospitalization. We included 750 patients (median age 67, IQR 56-77 years; 69% males), of whom 46.9% had history of hypertension, 14.7% of chronic coronary disease and 22.3% of chronic kidney disease (CKD). Abnormal troponin levels (median troponin 74, IQR 34-147 ng/l) were detected in 390 patients (52%) during the hospitalization. At multivariable analysis age, CKD, cancer, C-reactive protein (CRP) levels were independently associated with CI. Independent predictors of very high troponin levels were chronic kidney disease and CRP levels. Patients with CI showed higher rate of all-cause mortality (40.0% vs. 9.1%, p = 0.001) compared to those without CI. CONCLUSION: This large, multicentre Italian study confirmed the high prevalence of CI and its prognostic role in hospitalized patients with COVID-19, highlighting the leading role of systemic inflammation for the occurrence of CI.

Bedside intra-aortic balloon pump insertion in cardiac intensive care unit: A single-center experience.

BACKGROUND: In contemporary Cardiac Intensive Care Unit (CICU), bedside intra-aortic balloon pump (IABP) insertion under echocardiographic guidance may be an attractive option for selected patients with cardiogenic shock (CS). Currently available data on this approach are limited. AIM: This study aimed to assess the feasibility and safety of bedside IABP insertion, as compared to fluoroscopic-guided insertion in the Catheterization Laboratory (CathLab), and to describe the clinical features of patients receiving bedside IABP insertion using a standardized technique in real-world CICU practice. METHODS: We prospectively evaluated all patients admitted the CICU who received transfemoral IABP between June 2020 and October 2021. The overall study cohort was divided according to implant strategy in bedside and CathLab groups. The primary outcome was correct radiographic IABP positioning at the first bedside chest X-ray obtained after insertion. Secondary outcomes included IABP-related complications. RESULTS: Among 115 patients, bedside IABP insertion was performed in 35 (30.4%) cases, mainly presenting with CS-related to acute decompensated heart failure (ADHF) (68.6 vs 33.8%; p < 0.001), with lower LVEF, higher proportion of right ventricular involvement and higher need of inotropes/vasopressors, compared to those receiving CathLab insertion. Bedside IABP insertion resulted feasible and safe, with similar rates of correct IABP positioning (82.9 vs. 82.5%; p = 0.963) and IABP-related major vascular complications (5.7 vs. 5.0%; p = 0.874), as compared to CathLab positioning. CONCLUSION: This study suggests the feasibility and safety of bedside IABP insertion, which could be of relevant interest in patients with ADHF-related CS who may not need coronary angiography or other urgent CathLab procedures.

Use of extracorporeal membrane oxygenation in high-risk acute pulmonary embolism: A systematic review and meta-analysis.

Extracorporeal membrane oxygenation (ECMO) represents a therapeutic option for cardiopulmonary support in patients with high-risk pulmonary embolism (PE); however, no definite consensus exists on ECMO use in high-risk PE. Hence, we aim to provide insights into its real-world use pooling together all available published experiences. We performed a systematic review and pooled analysis of all published studies (up to April 17, 2020) investigating ECMO support in high-risk PE. All studies including at least four patients were collectively analyzed. Study outcomes were early all-cause death (primary endpoint) and relevant in-hospital adverse events. A total of 21 studies were included in the pooled analysis (n = 635 patients). In this population (mean age 47.8 ± 17.3 years, 44.5% females), ECMO was indicated for cardiac arrest in 62.3% and immediate ECMO support was pursued in 61.9% of patients. Adjunctive reperfusion therapies were implemented in 57.0% of patients. Pooled estimate rate of early all-cause mortality was 41.1% (95% CI 27.7%-54.5%). The most common in-hospital adverse event was major bleeding, with an estimated rate of 28.6% (95%CI 21.0%-36.3%). At meta-regression analyses, no significant impact of multiple covariates on the primary endpoint was found. In this systematic review of patients who received ECMO for high-risk PE, pooled all-cause mortality was 41.1%. Principal indication for ECMO was cardiac arrest, cannulation was chiefly performed at presentation, and major bleeding was the most common complication.

One-year clinical outcome of biodegradable polymer sirolimus-eluting stent in diabetic patients: Insight from the ULISSE registry (ULtimaster Italian multicenter all comerS Stent rEgistry).

BACKGROUND: The ULISSE registry evaluated the real-world performance of the Ultimaster® biodegradable polymer sirolimus-eluting stent (BP-SES) in a multicenter-independent cohort of patients undergoing percutaneous coronary intervention, including a large proportion of diabetes mellitus (DM) patients. METHODS: In this subgroup analysis, 1,660 consecutive patients, 2,422 lesions, treated with BP-SES enrolled in the ULISSE registry were divided in two groups: DM (485 patients, 728 lesions) and non-DM (1,175 patients, 1,694 lesions). Primary endpoint was target lesion failure (TLF), a composite endpoint of cardiac-death, target-vessel myocardial infarction (TV-MI), and clinically driven target lesion revascularization (TLR) at 1-year. Secondary endpoint was TLR at 1-year. RESULTS: At 1-year follow-up TLF occurred in 5% overall patients and was significantly higher in DM patients (8 vs. 3.7%; p = .001), due to more cardiac deaths (3.4 vs. 1.1%; p = .002). TLR occurred in 3.2% overall patients, and it was not significantly higher in DM compared to non-DM patients (4.4 vs. 2.8%; p = .114). The incidence of stent thrombosis was low and similar between groups (0.4 vs. 0.9%; p = .526). Insulin-treated DM (ITDM) patients showed higher rate of TLF as compared to non-ITDM patients (13 vs. 6.5%; p = .041), but similar rate of TLR (6 vs. 4%; p = .405). After adjustment for relevant comorbidities, DM was not significantly associated with TLF or cardiac death in patients undergoing BP-SES implantation. CONCLUSIONS: This study is the first all-comers evaluation of BP-SES in DM patients. Our findings show that DM patients, mostly those with ITDM, still represent a vulnerable population and experience significantly higher rate of TLF. Overall BP-SES efficacy is considerable, although not statistically significant higher rate of TLR is still present in DM compared to non-DM patients.

One-year clinical outcome of biodegradable polymer sirolimus-eluting stent in patients presenting with acute myocardial infarction: Insight from the ULISSE registry.

BACKGROUND: The ULISSE registry has demonstrated the real-world performance of the Ultimaster biodegradable polymer sirolimus-eluting stent (BP-SES) in a large cohort of patients undergoing percutaneous coronary intervention, including a large proportion of patients presenting with acute myocardial infarction (AMI). METHODS: We performed a subgroup analysis of the ULISSE registry in AMI patients and compared the outcomes of this vulnerable cohort with that of patients presenting without AMI (non-AMI). The primary end point was the incidence of 1-year target lesion failure (TLF), a composite of cardiac death, target vessel myocardial infarction (TV-MI), and clinically indicated target lesion revascularization (TLR). RESULTS: Of 1,660 patients included in the ULISSE registry, 381(23%) presented with AMI, 207(54.3%) non-ST elevation myocardial infarction, and 174(45.7%) ST-elevation myocardial infarction. Compared with non-AMI patients, those with AMI were more frequently female and smokers, with lower left ventricular ejection fraction (LVEF) and chronic kidney disease requiring dialysis. At 1 year, TLF rate was significantly higher in AMI than non-AMI patients (7.9 vs. 4.1%; HR 1.98, CI 95% 1.22-3.23; p = .005) driven by higher rate of cardiac death (4.0 vs. 1.1%; HR 3.59, CI 95% 1.64-7.88; p = .01) and TV-MI (2.8 vs 0.9%; HR 2.99,CI 95% 1.22-7.37; p = .01), without differences in TLR rate (4.3 vs. 2.9%,HR 0.66, CI95% 0.35-1.25; p = .2). At multivariate Cox regression analysis, eGFR <40 mL/min (HR: 2.868) and LVEF <40% (HR: 2.394) were the only independent predictors of TLF. CONCLUSIONS: In AMI patients, Ultimaster BP-SES implantation was associated with higher rate of TLF and definite stent thrombosis compared with non-AMI patients. The high incidence of adverse events was mainly driven by the unfavorable baseline risk profile.

PFO closure with only fluoroscopic guidance: 7 years real-world single centre experience.

AIMS: To evaluate the safety and the efficacy of fluoroscopy-guided only (Fluo-G) and of echocardiography-guided (Echo-G; trans-esophageal echocardiography-TEE-or intracardiac echocardiography-ICE) percutaneous closure of patent foramen ovale (PFO). METHODS AND RESULTS: Single center retrospective registry enrolling 368 consecutive patients (mean age 50.5 years) who underwent PFO closure between June 2004 and December 2011. Most patients had prior cryptogenic stroke (n = 126; 34.2%), TIA (n = 218; 51.1%); some of these had recurrent neurological events [multiple strokes n = 28 (7.8%); multiple TIAs n = 72 (18.6%)]. All the patients underwent a preprocedure TEE. PFO closure was performed with Echo-G in 187 patients (50.8%) (TEE n = 69, 36.8% and ICE n = 124, 66.3%). In Fluo-G cases, PFO with atrial septal aneurysm (ASA) was significantly less present (P < 0.005) and smaller devices (<25 mm) were implanted more frequently (P < 0.001). Both fluoroscopy and total procedural time were lower in the Fluo-G group (P < 0.0001). No differences were found in terms of successful device deployment (98.3% Fluo-G vs. 98.3% Echo-G) and RtL-shunt at follow-up (11.7% Fluo-G vs. 7.6% Echo-G). The rate of conversion from Fluoro-G to Echo-G procedure was 4.4% (n = 8). At a median follow-up of 4 years, freedom from recurrent embolic events rate was similar between the two groups (Echo-G 94.5 vs. Fluo-G 95.7%). CONCLUSIONS: In our experience Fluoro-G PFO closure was performed mainly in cases of simple anatomy, with similar results in terms of safety and efficacy compared to Echo-G cases. Both fluoroscopy and total procedural times were lower in the Fluo-G cases.

PlaCor PRT measurement of shear-activated platelet aggregate formation in stable patients treated with single and dual antiplatelet therapy.

Shear forces play a key role in thrombus formation and shear-based tests may better reflect physiological conditions in vivo compared with agonist-based tests. We evaluated the PlaCor PRT®, a novel platelet reactivity test based on shear-induced platelet aggregation, in patients with stable coronary artery disease (CAD) treated with single (SAPT) and dual antiplatelet therapy (DAPT). We examined 100 patients with multiple risk factors for CAD and/or documented stable CAD: 38 treated with SAPT, aspirin 100 mg qd, 62 treated with DAPT, aspirin 100 mg + clopidogrel 75 mg qd, compared with age- and sex-matched healthy volunteers without antiplatelet therapy (HV, n = 35). Measures of shear-induced platelet aggregation were performed with the PlaCor PRT®. In 25 patients in SAPT, the PlaCor test was also performed before and after a 12-hour-loading dose of clopidogrel 600 mg. The mean ± SD PRT time (seconds) in HV was 78 ± 13 and was significantly lower compared with SAPT (118 ± 16, p = 0.030) and to DAPT patients (242 ± 11, p < 0.0001). A statistically significant difference was also reported between SAPT and DAPT patients (p < 0.0001). After a loading dose of clopidogrel, the PRT time of SAPT patients increased significantly from 112 ± 20 to 254 ± 17, p < 0.0001. 2.7 and 26% of patients were considered as "poor responders" to single and dual antiplatelet therapy, respectively. This study shows that in patients with multiple risk factors for CAD and/or documented stable CAD, SAPT and DAPT play an important role in reducing platelet aggregation mediated by shear forces as evaluated with the novel PlaCor PRT®. Further studies will be required to confirm and assess the extent of these findings in patients with acute coronary syndromes.

Clinical burden and predictors of non-cardiovascular mortality and morbidity in advanced heart failure.

BACKGROUND: The changing demographic of heart failure (HF) increases the exposure to non-cardiovascular (non-CV) events. We investigated the distribution of non-CV mortality/morbidity and the characteristics associated with higher risk of non-CV events in patients with advanced HF. METHODS: Patients from the HELP-HF registry were stratified according to the number of 2018 HFA-ESC criteria for advanced HF. Endpoints were non-CV mortality and non-CV hospitalization. Competing risk analyses were performed assessing the association between HFA-ESC criteria and study outcomes and the additional predictors of non-CV endpoints. RESULTS: One thousand one hundred and forty-nine patients were included (median age 77 years-IQR 69-83). At 6, 12, 18 and 22 months, cumulative incidence of CV vs non-CV mortality was 13% vs 5%, 17% vs 8%, 20% vs 12%, 23% vs 12%, and of CV vs non-CV hospitalization was 26% vs 11%, 38% vs 17%, 45% vs 20%, 50% vs 21%. HFA-ESC criteria were associated with increasing adjusted risk of CV death, whereas no association was observed for CV hospitalization, non-CV death and non-CV hospitalization. Predictors of non-CV death were age, chronic obstructive pulmonary disease, dementia, preserved ejection fraction, >1 HF hospitalization and hemoglobin. CONCLUSIONS: Patients with advanced HF are exposed to high, even though not predominant, burden of non-CV outcomes. HFA-ESC criteria aid to stratify the risk of CV death, but are not associated with lower competing risk of non-CV outcomes. Alternative factors can be useful to define the patients with advanced HF at risk of non-CV events in order to better select patients for treatments specifically reducing CV risk.

Role of ejection fraction in patients at risk for advanced heart failure: insights from the HELP-HF registry.

AIMS: Patients with heart failure (HF) with reduced ejection fraction (EF) (HFrEF), mildly reduced EF (HFmrEF), and preserved EF (HFpEF) may all progress to advanced HF, but the impact of EF in the advanced setting is not well established. Our aim was to assess the prognostic impact of EF in patients with at least one 'I NEED HELP' marker for advanced HF. METHODS AND RESULTS: Patients with HF and at least one high-risk 'I NEED HELP' criterion from four centres were included in this analysis. Outcomes were assessed in patients with HFrEF (EF ≤ 40%), HFmrEF (EF 41-49%), and HFpEF (EF ≥ 50%) and with EF analysed as a continuous variable. The prognostic impact of medical therapy for HF in patients with EF < 50% and EF > 50% was also evaluated. All-cause death was the primary endpoint, and cardiovascular death was a secondary endpoint. Among 1149 patients enrolled [mean age 75.1 ± 11.5 years, 67.3% males, 67.6% hospitalized, median follow-up 260 days (inter-quartile range 105-390 days)], HFrEF, HFmrEF, and HFpEF were observed in 699 (60.8%), 122 (10.6%), and 328 (28.6%) patients, and 1 year mortality was 28.3%, 26.2%, and 20.1, respectively (log-rank P = 0.036). As compared with HFrEF patients, HFpEF patients had a lower risk of all-cause death [adjusted hazard ratio (HRadj ) 0.67, 95% confidence interval (CI) 0.48-0.94, P = 0.022], whereas no difference was noted for HFmrEF patients. After multivariable adjustment, a lower risk of all-cause death (HRadj for 5% increase 0.94, 95% CI 0.89-0.99, P = 0.017) and cardiovascular death (HRadj for 5% increase 0.94, 95% CI 0.88-1.00, P = 0.049) was observed at higher EF values. Beta-blockers and renin-angiotensin system inhibitors or sacubitril/valsartan were associated with lower mortality in both EF < 50% and EF ≥ 50% groups. CONCLUSIONS: Among patients with HF and at least one 'I NEED HELP' marker for advanced HF, left ventricular EF is still of prognostic value.

Characteristics and outcomes of patients with tricuspid regurgitation and advanced heart failure.

AIMS: To evaluate the role of tricuspid regurgitation in advanced heart failure. METHODS: The multicenter observational HELP-HF registry enrolled consecutive patients with heart failure and at least one 'I NEED HELP' criterion evaluated at four Italian centers between January 2020 and November 2021. Patients with no data on tricuspid regurgitation and/or receiving tricuspid valve intervention during follow-up were excluded. The population was stratified by no/mild tricuspid regurgitation vs. moderate tricuspid regurgitation vs. severe tricuspid regurgitation. Variables independently associated with tricuspid regurgitation, as well as the association between tricuspid regurgitation and clinical outcomes were investigated. The primary outcome was all-cause mortality. RESULTS: Among the 1085 patients included in this study, 508 (46.8%) had no/mild tricuspid regurgitation, 373 (34.4%) had moderate tricuspid regurgitation and 204 (18.8%) had severe tricuspid regurgitation. History of atrial fibrillation, any prior valve surgery, high dose of furosemide, preserved left ventricular ejection fraction, moderate/severe mitral regurgitation and pulmonary hypertension were found to be independently associated with an increased likelihood of severe tricuspid regurgitation. Estimated rates of 1-year all-cause death were of 21.4, 24.5 and 37.1% in no/mild tricuspid regurgitation, moderate tricuspid regurgitation and severe tricuspid regurgitation, respectively (log-rank P  < 0.001). As compared with nonsevere tricuspid regurgitation, severe tricuspid regurgitation was independently associated with a higher risk of all-cause mortality (adjusted hazard ratio 1.38, 95% confidence interval 1.01-1.88, P  = 0.042), whereas moderate tricuspid regurgitation did not. CONCLUSION: In a contemporary, real-world cohort of patients with advanced heart failure, several clinical and echocardiographic characteristics are associated with an increased likelihood of severe tricuspid regurgitation. Patients with severe tricuspid regurgitation have an increased risk of mortality.

Guideline-directed medical therapy in severe heart failure with reduced ejection fraction: An analysis from the HELP-HF registry.

AIM: Persistent symptoms despite guideline-directed medical therapy (GDMT) and poor tolerance of GDMT are hallmarks of patients with advanced heart failure (HF) with reduced ejection fraction (HFrEF). However, real-world data on GDMT use, dose, and prognostic implications are lacking. METHODS AND RESULTS: We included 699 consecutive patients with HFrEF and at least one 'I NEED HELP' marker for advanced HF enrolled in a multicentre registry. Beta-blockers (BB) were administered to 574 (82%) patients, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers or angiotensin receptor-neprilysin inhibitors (ACEi/ARB/ARNI) were administered to 381 (55%) patients and 416 (60%) received mineralocorticoid receptor antagonists (MRA). Overall, ≥50% of target doses were reached in 41%, 22%, and 56% of the patients on BB, ACEi/ARB/ARNI and MRA, respectively. Hypotension, bradycardia, kidney dysfunction and hyperkalaemia were the main causes of underprescription and/or underdosing, but up to a half of the patients did not receive target doses for unknown causes (51%, 41%, and 55% for BB, ACEi/ARB/ARNI and MRA, respectively). The proportions of patients receiving BB and ACEi/ARB/ARNI were lower among those fulfilling the 2018 HFA-ESC criteria for advanced HF. Treatment with BB and ACEi/ARB/ARNI were associated with a lower risk of death or HF hospitalizations (adjusted hazard ratio [HR] 0.63, 95% confidence interval [CI] 0.48-0.84, and HR 0.74, 95% CI 0.58-0.95, respectively). CONCLUSIONS: In a large, real-world, contemporary cohort of patients with severe HFrEF, with at least one marker for advanced HF, prescription and uptitration of GDMT remained limited. A significant proportion of patients were undertreated due to unknown reasons suggesting a potential role of clinical inertia either by the prescribing healthcare professional or by the patient. Treatment with BB and ACEi/ARB/ARNI was associated with lower mortality/morbidity.

Frailty according to the 2019 HFA-ESC definition in patients at risk for advanced heart failure: Insights from the HELP-HF registry.

AIMS: Frailty is highly prevalent in patients with heart failure (HF), but a concordant definition of this condition is lacking. The Heart Failure Association of the European Society of Cardiology (HFA-ESC) proposed in 2019 a new multi-domain definition of frailty, but it has never been validated. METHODS AND RESULTS: Patients from the HELP-HF registry were stratified according to the number of HFA-ESC frailty domains fulfilled and to the cumulative deficits frailty index (FI) quintiles. Prevalence of frailty and of each domain was reported, as well as the rate of the composite of all-cause death and HF hospitalization, its single components, and cardiovascular death in each group and quintile. Among 854 included patients, 37 (4.3%), 206 (24.1%), 365 (42.8%), 217 (25.4%), and 29 (3.4%) patients fulfilled zero, one, two, three, or four domains, respectively, while 179 patients had a FI < 0.21 and were considered not frail. The 1-year risk of adverse events increased proportionally to the number of domains fulfilled (for each criterion increase, all-cause death or HF hospitalization: hazard ratio [HR] 1.43, 95% confidence interval [CI] 1.27-1.62; all-cause death: HR 1.72, 95% CI 1.46-2.02, HF hospitalizations: subHR 1.21, 95% CI 1.04-1.31; cardiovascular death: HR 1.77, 95% CI 1.45-2.15). Consistent results were found stratifying the cohort for FI quintiles. The FI as a continuous variable demonstrated higher discriminative ability than the number of domains fulfilled (area under the curve = 0.68 vs. 0.64, p = 0.004). CONCLUSION: Frailty in patients at risk for advanced HF, assessed via a multi-domain approach and the FI, is highly prevalent and identifies those at increased risk of adverse events. The FI was found to be slightly more effective in identifying patients at increased risk of mortality.

Impact of malnutrition in patients with severe heart failure.

AIM: The role of malnutrition among patients with severe heart failure (HF) is not well established. We evaluated the incidence, predictors, and prognostic impact of malnutrition in patients with severe HF. METHODS AND RESULTS: Nutritional status was measured using the geriatric nutritional risk index (GNRI), based on body weight, height and serum albumin concentration, with malnutrition defined as GNRI ≤98. It was assessed in consecutive patients with severe HF, defined by at least one high-risk 'I NEED HELP' marker, enrolled at four Italian centres between January 2020 and November 2021. The primary endpoint was all-cause mortality. A total of 510 patients with data regarding nutritional status were included in the study (mean age 74 ± 12 years, 66.5% male). Among them, 179 (35.1%) had GNRI ≤98 (malnutrition). At multivariable logistic regression, lower body mass index (BMI) and higher levels of natriuretic peptides (B-type natriuretic peptide [BNP] > median value [685 pg/ml] or N-terminal proBNP > median value [5775 pg/ml]) were independently associated with a higher likelihood of malnutrition. Estimated rates of all-cause death at 1 year were 22.4% and 41.1% in patients without and with malnutrition, respectively (log-rank p < 0.001). The impact of malnutrition on all-cause mortality was confirmed after multivariable adjustment for relevant covariates (adjusted hazard ratio 2.03, 95% confidence interval 1.43-2.89, p < 0.001). CONCLUSION: In a contemporary, real-world, multicentre cohort of patients with severe HF, malnutrition (defined as GNRI ≤98) was common and independently associated with an increased risk of mortality. Lower BMI and higher natriuretic peptides were identified as predictors of malnutrition in these patients.

Clinical and prognostic implications of heart failure hospitalization in patients with advanced heart failure.

BACKGROUND: Hospitalization is associated with poor outcomes in patients with heart failure, but its prognostic role in advanced heart failure is still unsettled. We evaluated the prognostic role of heart failure hospitalization in patients with advanced heart failure. METHODS: The multicenter HELP-HF registry enrolled consecutive patients with heart failure and at least one high-risk 'I NEED HELP' marker. Characteristics and outcomes were compared between patients who were hospitalized for decompensated heart failure (inpatients) or not (outpatients) at the time of enrolment. The primary endpoint was the composite of all-cause mortality or first heart failure hospitalization. RESULTS: Among the 1149 patients included [mean age 75.1 ±â€Š11.5 years, 67.3% men, median left ventricular ejection fraction (LVEF) 35% (IQR 25-50%)], 777 (67.6%) were inpatients at the time of enrolment. As compared with outpatients, inpatients had lower LVEF, higher natriuretic peptides and a worse clinical profile. The 1-year rate of the primary endpoint was 50.9% in inpatients versus 36.8% in outpatients [crude hazard ratio 1.70, 95% confidence interval (CI) 1.39-2.07, P < 0.001]. At multivariable analysis, inpatient status was independently associated with a higher risk of the primary endpoint (adjusted hazard ratio 1.54, 95% CI 1.23-1.93, P < 0.001). Among inpatients, the independent predictors of the primary endpoint were older age, lower SBP, heart failure association criteria for advanced heart failure and glomerular filtration rate 30 ml/min/1.73 m2 or less. CONCLUSION: Hospitalization for heart failure in patients with at least one high-risk 'I NEED HELP' marker is associated with an extremely poor prognosis supporting the need for specific interventions, such as mechanical circulatory support or heart transplantation.

Effects of Intra-Aortic Balloon Pump delayed deflation timing on carotid blood flow and cardiac mechanics: An ultrasound and haemodynamic study.

Intra-Aortic Balloon Pump (IABP) efficacy is critically affected by the inflation/deflation timing. Balloon deflation may cause a sucking effect, and a steal phenomenon on carotid flow. Delaying IABP deflation reduces the degree of this flow reversal, but at the same time exposes patients to the risk of increased proto-systolic afterload with detrimental effects on the LV. The purpose of this study was to investigate the effects of a delayed IABP deflation timing on cerebral blood flow and LV hemodynamics, by means of simultaneous carotid artery ultrasonography, trans-thoracic echocardiography and central aortic pressure analysis. Delaying IABP deflation trigger to the beginning of QRS effectively increased the cerebral blood flow by 20%, mostly by reducing the reverse component flow caused by the diastolic balloon deflation. Extending the deflation to the early systole was safe and favourably impacted on cardiac mechanics, increasing CO by 15% without prolonging LV isovolumetric contraction and ejection phases.

Safety and efficacy of direct oral anticoagulants (DOACs) in very elderly patients (≥85 years old) with non-valvular atrial fibrillation.

BACKGROUND: Limited real-world data are available regarding the comparison about safety and efficacy of DOACs prescription in very elderly patients (≥85 years) with non-valvular atrial fibrillation (NVAF). Concern about the risk of bleeding with anticoagulation in very older patients still represents an important challenge for clinicians. The aim of this study was to evaluate the different prevalence of major bleeding and thromboembolic events between very elderly NVAF patients (≥85 years) compared to those non very elderly (<85 years). METHODS: Single center multidisciplinary registry including NVAF patients treated with DOACs. Primary safety endpoint was 2-year rate of major bleeding. Primary efficacy endpoint was 2-year rate of thromboembolic events. Event-free survival curves among groups were compared using Cox-Mantel Test. RESULTS: 908 NVAF consecutive patients were included, of these, 805 patients were <85 years (89%) and 103 patients were very elderly patients with ≥85 years (11%). Compared to patients <85 years, those very elderly have higher CHA2DS2-VASc Score (P=0.001), higher rate of hypertension (P=0.001), diabetes mellitus (P=0.030), previous bleeding events (P<0.001), previous stroke/TIA/SE (P≤0.001), heart failure (P≤0.001), and lower creatinine clearance (P<0.001). In terms of safety endpoints (overall ISTH-major bleeding) no significative difference between two groups (P=0.952) were observed up to 2-year follow-up. Systemic thromboembolic event (primary efficacy endpoint) was significantly higher in patients with ≥85 years (P=0.027). The incidence of all-cause death was significantly higher in very elderly patients (P<0.001). CONCLUSIONS: This single center registry, showed that the use of DOACs in very elderly NVAF was safe and is a therapeutic option to be pursued for stroke prevention especially for those who are at high risk of ischemic events.

Ischemic Etiology in Advanced Heart Failure: Insight from the HELP-HF Registry.

In patients with advanced heart failure (HF), defined according to the presence of at least one I-NEED-HELP criterium, the updated 2018 Heart Failure Association of the European Society of Cardiology (HFA-ESC) criteria for advanced HF identify a subgroup of patients with HF with worse prognosis, but whether ischemic etiology has a relevant prognostic impact in this very high-risk cohort is unknown. Patients from the HELP-HF registry were stratified according to ischemic etiology and presence of advanced HF based on 2018 HFA-ESC criteria. The primary end point was a composite of all-cause death and HF hospitalization at 1 year. Secondary end points were all-cause death, HF hospitalization, and cardiovascular death at 1 year. Ischemic etiology was a leading cause of HF, in both patients with advanced and nonadvanced HF (46.1% and 42.4%, respectively, p = 0.337). The risk of the primary end point (hazard ratio [HR] 1.31, 95% confidence interval [CI] 1.09 to 1.58) and all-cause mortality (HR 1.37, 95% CI 1.06 to 1.76) was increased in ischemic as compared with nonischemic patients. The risk of the primary end point was consistently higher in ischemic patients in both patients with advanced and nonadvanced HF (advanced HF, HR 1.50 95% CI 1.04 to 2.16; nonadvanced HF, HR 1.25 95% CI 1.01 to 1.56, pinteraction = 0.333), driven by an increased risk of mortality, mainly because of cardiovascular causes. In conclusion, ischemic etiology is the most common cause of HF in patients with at least one I-NEED-HELP marker and with or without advanced HF as defined by the 2018 HFA-ESC definition. In both patients with advanced and not-advanced HF, ischemic etiology carried an increased risk of worse prognosis.
