Abstract
BACKGROUND Interleukin-1 blockade with anakinra reduces high-sensitivity C-reactive protein (hsCRP) levels and prevents heart failure (HF) events after ST-segment myocardial infarction (STEMI). Sex-based differences in STEMI patients have been reported, but no data are available regarding response to anakinra. METHODS We analyzed the systemic inflammation and composite end-point of new-onset HF or death in women and men with STEMI treated with anakinra from three different Virginia Commonwealth University Anakinra Response Trial (VCUART) randomized clinical trials. RESULTS We analyzed 139 patients, 29 (21%) were women while 110 (79%) were men. Baseline hsCRP was higher in women compared to men (8.9 [5.2-13.5] vs. 4.2 [2.1-7.7] mg/L, P<0.001). Eighty-four patients were treated with anakinra (22 [75%] women and 62 [56%] men). The area under the curve of hsCRP (hsCRP-AUC) after 14 days was numerically lower in patients receiving anakinra versus placebo both in men (86 [37-130] vs. 223 [119-374] mg day/L) and in women (73 [46-313] vs. 242 [102-988] mg day/L) (P<0.001 for multiple groups, P for interaction 0.22). The incidence of the composite endpoint was also numerically lower in the anakinra group compared to placebo, both in men (4 [6.4%] vs. 14 [29.1%]) and in women (3 [13.6%] vs. 2 [28.5%]) (P=0.019 for multiple groups, P for interaction 0.44). There were no statistically significant differences between women and men in hsCRP-AUC and death or HF events when comparing separately the anakinra and placebo groups (all P>0.05). CONCLUSIONS Women were underrepresented in the VCUART trials, they appeared to have higher hsCRP levels at time of presentation, yet to benefit similar to men by treatment with anakinra in STEMI.

Abstract
BACKGROUND Atrial fibrillation is the most common arrhythmia worldwide and is associated with significant morbidity and mortality. Despite the effectiveness of catheter-based ablation, periprocedural complication and recurrences remain a concern. In this context, we aim to appraise the potential impact of brain-derived neurotrophic factor (BDNF) on reducing episodes of paroxysmal atrial fibrillation (PAF). METHODS 22 patients with an established diagnosis of PAF and without structural heart disease were considered. Every patient received 20 drops of GUNA-BDNF administered in the morning. During the 24 months of follow-up, the arrhythmic burden was measured by the average monthly duration of PAF episodes. RESULTS At the end of the follow-up period (24 months), data from 22 patients, of whom 17 men and five women, were analyzed. The arrhythmic burden, measured in terms of average monthly duration of PAF episodes, was found significantly reduced after the administration of low dose BDNF (9.5 vs. 65.3 minutes per month, P<0.001). A total of 17 out of 22 patients saw their arrhythmic burden eliminated or consistently reduced, furthermore two patients underwent a drastic reduction of the average monthly duration of AF (more than 200 minutes compared to the baseline). Only four patients, despite the administration of BDNF, still experienced an arrhythmic burden of 20 minutes or more. Considering the age groups, the major reduction was observed in people aged 70 or more, who were also the most represented in the sample. These results are coherent with the poor literature currently available. CONCLUSIONS BDNF low dose therapy has shown to have an impacting role in reducing the arrhythmic burden and recurrences of AF, with a particular effectiveness in patients over 70 and without structural heart disease. We should welcome this work, despite it limitations. Further clinical and molecular studies are needed before-considering BDNF low dose as a tool against PAF.

Abstract
Iatrogenic coronary artery dissections (ICAD) are rare but potentially devastating complications during coronary angiography and percutaneous coronary interventions (PCI). Intima media complex separation may be produced either by the catheter tip or during PCI. Patient characteristics and procedure related risk factors are intimately linked to catheter induced ICAD over diagnostic angiography. Moreover, the increasing complexity of patients undergoing PCI, which frequently involves treatment of heavily calcified or occluded vessels, has increased the likelihood of dissections during PCI. A prompt recognition, along with a prompt management (either percutaneous, surgical or even careful watching), are key in preventing catastrophic consequences of ICAD, such as left ventricular dysfunction, cardiogenic shock, periprocedural myocardial infarction (MI) or cardiac death. This review aims to summarize the main updates concerning the pathophysiology, highlight key risk factors and suggest recommendations in management and treatment of ICAD.

Abstract
Pre-clinical and clinical studies suggest a role for inflammation in the pathophysiology of cardiovascular (CV) diseases. The NLRP3 (NACHT, leucine-rich repeat, and pyrin domain-containing protein 3) inflammasome is activated during tissue injury and releases interleukin-1β (IL-1β). We describe three paradigms in which the NLRP3 inflammasome and IL-1β contribute to CV diseases. During acute myocardial infarction (AMI), necrotic cell debris, including IL-1α, induce NLRP3 inflammasome activation and further damage the myocardium contributing to heart failure (HF) (acute injury paradigm). In chronic HF, IL-1β is induced by persistent myocardial overload and injury, neurohumoral activation and systemic comorbidities favoring infiltration and activation of immune cells into the myocardium, microvascular inflammation, and a pro-fibrotic response (chronic inflammation paradigm). In recurrent pericarditis, an autoinflammatory response triggered by cell injury and maintained by the NLRP3 inflammasome/IL-1β axis is present (autoinflammatory disease paradigm). Anakinra, recombinant IL-1 receptor antagonist, inhibits the acute inflammatory response in patients with ST elevation myocardial infarction (STEMI) and acute HF. Canakinumab, IL-1β antibody, blunts systemic inflammation and prevents complications of atherosclerosis in stable patients with prior AMI. In chronic HF, anakinra reduces systemic inflammation and improves cardiorespiratory fitness. In recurrent pericarditis, anakinra and rilonacept, a soluble IL-1 receptor chimeric fusion protein blocking IL-1α and IL-1β, treat and prevent acute flares. In conclusion, the NLRP3 inflammasome and IL-1 contribute to the pathophysiology of CV diseases, and IL-1 blockade is beneficial with different roles in the acute injury, chronic inflammation and autoinflammatory disease paradigms. Further research is needed to guide the optimal use of IL-1 blockers in clinical practice.

Abstract
BACKGROUND Previous studies have shown that patients with heart failure with reduced ejection fraction (HFrEF) and anemia have reduced peak oxygen consumption (VO2). Black or African American (B-AA) patients have a higher prevalence of anemia and are underrepresented in clinical studies of HFrEF. The aim of this study was to determine the contribution of hemoglobin to peak VO2 in B-AA patients recently hospitalized for acute decompensated HFrEF. METHODS We analyzed cardiopulmonary exercise testing (CPX) data measured within two weeks of discharge for acute decompensated HF in B-AA patients with HFrEF (left ventricular ejection fraction [LVEF] ≤40%) without severe anemia (Hb<8 g/dL). Blood samples were collected prior to CPX. Data are reported as median [interquartile range] and compared between groups with the Mann-Whitney, Chi-Square, and Spearman's rank tests. RESULTS We included 81 patients; 27 (33%) women, 57 [27-79] years of age, Body Mass Index of 33 [15-55] kg/m2 and LVEF of 30 [23-36] %. Hemoglobin ranged between 9.1 to 18.1 g/dL (median= 13.3 [11.9-14.5] g/dL); 26 (32%) were considered to have anemia based on a Hb concentration of males <13 g/dL and females <12 g/dL. Peak VO2 was lower in patients with anemia (11.8 [10.0-14.2] vs. 14.1 [10.6-17.0] mL·kg-1·min-1; P=0.010) with a significant correlation between peak VO2 and hemoglobin concentration (R=+0.455; P<0.001). CONCLUSIONS Anemia is prevalent among B-AA patients with recently decompensated HFrEF and appears to be a significant contributor to reductions in peak VO2.

Abstract
Atrial fibrillation (AF) is responsible for up to one-third of ischemic strokes, with stroke potentially being the first manifestation of a previously undetected AF. Given the efficacy of oral anticoagulants in preventing AF-related ischemic events, searching for unknown AF after stroke requires a comprehensive diagnostic workup. Prospective data have demonstrated the benefits of long-term cardiac monitoring to identify AF in association with cryptogenic stroke, as most strokes are presumed to result from AF. However, strategies of empirical anticoagulation using oral anticoagulants following cryptogenic stroke failed to improve outcomes. We herein summarize contemporary evidence and knowledge gaps on searching for AF after a stroke and the potential secondary prevention strategies to prevent further recurrences.

Abstract
Diabetes mellitus (DM) is frequent among heart failure (HF) patients with a further projected increase in prevalence in next years. DM promotes the development of both HF with reduced (HFrEF) and preserved ejection fraction (HFpEF) through different mechanisms. As the general prevalence of both DM and HF is growing worldwide, it is important to define the pathophysiologic mechanisms driving the development of HF in DM patients. These include changes in the cardiac metabolism, mitochondrial dysfunction, impairment in insulin signaling, maladaptive inflammation, coronary microvascular dysfunction, endoplasmic reticulum stress, autophagy suppression, and structural changes, among the main ones. In recent years, novel glucose-lowering treatments, especially sodium-glucose cotransporter 2 inhibitors (SGLT-2is), have shown a strikingly positive impact on the natural history of HF. This has led to a progressive change in choosing SGLT-2is in DM patients at high risk for CV disease, supported by recent guidelines. The knowledge about novel pathophysiological mechanisms linking DM and HF may open the way to the development of new targeted therapies in the future. In this review, we will summarize general aspects dealing with incidence, prevalence, and pathophysiology of DM in HF patients. As well, we discuss the therapeutic targets to reduce the disease burden and the current evidence of glucose-lowering drugs in patients with DM and HF.

Abstract
BACKGROUND Takotsubo syndrome (TS) is an acute, reversible form of heart failure, often mimicking an acute coronary syndrome (ACS). Data regarding racial differences in TS are inconsistent. The aim is to assess clinical features associated with unfavorable in-hospital outcomes between African American (AA) and Caucasian (CAU) patients. METHODS A retrospective electronic health record query identified 44 AA patients and 110 CAU patients with a diagnosis of TS. Our primary outcome was a composite of death, stroke, and cardiogenic shock during hospitalization. Variables associated with an increased risk of the primary composite outcomes were included in a logistic regression model. RESULTS Compared to CAU patients, AA patients were a more comorbid population, and presented a higher prevalence of history of illicit drug use (27.3% vs. 13.6% P=0.044). There were no significant differences regarding in-hospital complication rates between AA and CAU patients. In the logistic regression model, infection was associated with greater risk of developing the primary outcome in AA patients (OR=7.26 [95% CI 1.22-43.17], P=0.029), whereas angina was a protective factor (OR=0.11 [95% CI 0.02-0.65], P=0.015). In CAU patients, severely depressed ejection fraction and worse peak creatinine during hospitalization increased risk of developing the primary outcome (OR=5.88 95% CI [2.01-17.17], P<0.001 and OR=1.64 [95% CI 1.15-2.58], P=0.031, respectively). Meanwhile, emotional stressors were protective (OR=0.16 [95% CI 0.03-0.88], P=0.004). CONCLUSIONS Despite experiencing the same rate of in-hospital complications, the clinical profiles of AA patients are distinct from CAU patients admitted for TS, and clinical variables correlated with worse in-hospital outcomes also differ by race.

Abstract
Over the last decades, inflammation proved to play a pivotal role in atherosclerotic plaque formation, progression and destabilization. Several studies showed that the patients presenting with acute coronary syndrome are at increased risk of adverse cardiovascular events at both short- and long-term follow-up. Results from different clinical trials highlighted that a residual inflammatory risk exist and targeting inflammation is a successful strategy in selected cases associated to an increased inflammatory burden. Recently, the optimization of intracoronary and multimodality imaging allowed to also assess the entity of local inflammation, thus encouraging the individuation of plaque characteristics that portend a higher risk of future cardiovascular events. In this short review, we aim to highlight the role of systemic and local inflammation in acute coronary syndromes, to provide a summarized overview of the possible medical strategies applicable in selected cases and to underline the diagnostic and prognostic potential of multimodality imaging.

Abstract
INTRODUCTION Long-term efficacy and safety of either surgical or percutaneous treatment left main coronary artery disease treatment is lacking. EVIDENCE ACQUISITION We conducted a systematic review and meta-analysis of the most updated randomized clinical trials that compared the efficacy of coronary artery bypass surgery (CABG) or percutaneous coronary intervention (PCI) for the Left Main Coronary Artery (LMCA) disease. It was also conducted a systematic search of PubMed, Google Scholar, reference lists of relevant articles, and Medline. The search utilized the following terms: "left main PCI versus CABG," "drug-eluting stents," "bypass surgery" and "left main stenting." The search of articles compatible with our inclusion and exclusion criteria was performed from inception through April 2020 and returned a combined total of 304 articles. EVIDENCE SYNTHESIS We identified 6 studies, providing data on 5812 patients. The mean follow-up was 6.7 years. PCI was associated with an increased risk of major vascular events (MACE) (IRR 1.24, 95% CI [1.03-1.67], P<0.01), and coronary revascularization (IRR 1.69, 95% CI [1.42-2.03], P<0.01) compared to CABG. Furthermore, all-cause death, MI and stroke events were not statistically different between the two therapeutic revascularization methodologies (IRR 1.06, 95% CI [0.90-1.24], P=0.47, IRR 1.35, 95% CI [0.84-2.16], P=0.03 and IRR 0.66, 95% CI [0.43-1.01], P=0.05, respectively). CONCLUSIONS LMCA PCI has an overall same survival compared to CABG in the long term follow-up. Nevertheless, MACE and revascularization events were more frequent in PCI compared to CABG.

Abstract
BACKGROUND Previous studies suggested that N-terminal pro-brain natriuretic peptide (NT-proBNP) level is a powerful independent predictor of death or heart failure (HF) when measured at admission in patients with chest pain or acute coronary syndrome. Little is known about the role of NT-proBNP level measured during a hospitalization for ST segment elevation myocardial infarction (STEMI) in predicting clinical outcomes. We evaluated the optimal NT-proBNP timing (admission, 72 hours, or delta [Δ] NT-proBNP [72 hours minus admission]) to predict 1-year new-onset HF in STEMI patients. METHODS We measured NT-proBNP levels at admission and 72 hours in 72 patients with STEMI. HF events were adjudicated and defined as hospitalization for HF or need for new initiation of a loop diuretic at 1-year follow-up. Values are presented as medians and interquartile range or frequencies (%) as appropriate. Cox regression analysis was used to determine predictors of adverse events. A receiver-operative-curve was constructed to identify the discriminative value and optimal cut-off points for NT-proBNP. RESULTS Patients (age 56 [49-64] years, males 59 [82%]) were followed for a median duration of 365 [180-365] days. HF events were recorded in 9 (12.5%) patients. NT-proBNP values at admission, 72 hours, and ΔNT-proBNP were 89 (26-268) pg/mL, 452 (223-1064) pg/mL, and 283 (68-686) pg/mL, respectively. NT-proBNP at 72 hours and ΔNT-proBNP, but not admission NT-proBNP predicted new-onset HF events at follow-up (P=0.03, P=0.002 and P=0.89, respectively). The optimal area under the curve of 0.771 (95%, CI [0.630-0.912], P= 0.009) and cut-off value of 830 pg/mL (sensitivity 79%; specificity 76%) were found for NT-proBNP at 72 hours. The Kaplan-Meier survival curves for NT-proBNP at 72 hours dichotomized above and below this cut-off value, confirmed NT-proBNP at 72 hours >830 pg/mL as predictive of HF events (log-rank statistic = 8.688, P=0.003). CONCLUSIONS NT-proBNP level at 72 hours and ΔNT-proBNP (72 hours minus admission), but not at time of admission, predicted HF events in patients following STEMI.

Abstract
Background Enhanced inflammation may lead to exercise intolerance in heart failure with preserved ejection fraction. The aim of the current study was to determine whether IL (interleukin)-1 blockade with anakinra improved cardiorespiratory fitness in heart failure with preserved ejection fraction. Methods and Results Thirty-one patients with heart failure with preserved ejection fraction and CRP (C-reactive protein) >2 mg/L were randomized to anakinra (100 mg subcutaneously daily, N=21) or placebo (N=10) for 12 weeks. We measured peak oxygen consumption (Vo2), ventilatory efficiency (VE/Vco2 slope), and high-sensitivity CRP and NT-proBNP (N-terminal pro-B-type natriuretic peptide) at 4, 12, and 24 weeks. Twenty-eight patients completed ≥2 visits, 18 women (64%), 27 (96%) obese. There were no differences in peak Vo2 or VE/Vco2 slope between groups at baseline. Peak Vo2 was not changed after 12 weeks of anakinra (from 13.6 [11.8-18.0] to 14.2 [11.2-18.5] mL·kg-1·min-1, P=0.89), or placebo (14.9 [11.7-17.2] to 15.0 [13.8-16.9] mL·kg-1·min-1, P=0.40), without significant between-group differences in changes at 12 weeks (-0.4 [95% CI, -2.2 to +1.4], P=0.64). VE/Vco2 slope was also unchanged with anakinra (from 28.3 [27.2-33.0] to 30.5 [26.3-32.8], P=0.97) or placebo (from 31.6 [27.3-36.9] to 31.2 [27.8-33.4], P=0.78), without significant between-group differences in changes at 12 weeks (+1.2 [95% CI, -1.8 to +4.3], P=0.97). Within the anakinra-treated patients, high-sensitivity CRP and NT-proBNP levels were lower at 4 weeks compared with baseline ( P=0.026 and P=0.022 versus placebo [between-group analysis], respectively). Conclusions Treatment with anakinra for 12 weeks failed to improve peak Vo2 and VE/Vco2 slope in a group of obese heart failure with preserved ejection fraction patients. The favorable trends in high-sensitivity CRP and NT-proBNP with anakinra deserve exploration in future studies. Clinical Trial Registration URL: https://www.clinicaltrials.gov .

Abstract
BACKGROUND Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous syndrome that presents clinicians with a diagnostic challenge. The use of natriuretic peptides to exclude a diagnosis of HFpEF has been proposed. We sought to compare HFpEF patients with N-terminal pro-brain natriuretic peptide (NT-proBNP) level above and below the proposed cut-off. METHODS Stable patients (n = 30) with left ventricular (LV) ejection fraction ≥ 50% were eligible if they had a diagnosis of HF according to the European Society of Cardiology diagnostic criteria. Characteristics of patients with NT-proBNP below (≤125 pg/mL) and above (>125 pg/mL) the diagnostic criterion were compared. RESULTS There were 19 (66%) women with median age 54 years. Half were African American (16, 53%), and most were obese. There were no significant differences in clinical characteristics or medication use between groups. LV end-diastolic volume index was greater in high NT-proBNP patients (P = 0.03). Left atrial volume index, E/e' ratio, and E/e' ratio at peak exercise were not significantly different between NT-proBNP groups. Peak oxygen consumption (VO2 ), VO2 at ventilatory threshold, and ventilatory efficiency measures were impaired in all patients and were not significantly different between high and low NT-proBNP patients. CONCLUSIONS NT-proBNP was below the proposed diagnostic cut-off point of 125 pg/mL in half of this obese study cohort. Cardiac diastolic dysfunction and cardiorespiratory fitness were not significantly different between high and low NT-proBNP patients. These data indicate that excluding the diagnosis of HFpEF based solely on NT-proBNP levels should be discouraged.
