Empagliflozin: primum inter pares among sodium-glucose cotransporter-2 inhibitors?

Sodium/glucose cotransporter 2 (SGLT2) inhibitors are a novel class of anti-diabetic medications which have proved capable of providing breakthrough cardiovascular benefits in a variety of clinical scenarios, including patients with heart failure or obesity, irrespective of diabetic status. Several SGLT2 inhibitors are available, but the most prominent ones are canagliflozin, dapagliflozin, and empagliflozin. Several studies have focused on empagliflozin, and its effects on the risk of heart failure incidence and recurrences. Most recently, empagliflozin has been recently tested in patients with recent myocardial infarction in the EMPAgliflozin on Hospitalization for Heart Failure and Mortality in Patients With aCuTe Myocardial Infarction (EMPACT-MI) randomized trial, with apparently ambiguous findings. The present viewpoint succinctly illustrates the main features of SGLT2 inhibitors as a pharmacologic class, their ever expanding role as a cardiovascular medication, and the comparative effectiveness of different individual SGLT2 inhibitors, explicitly commenting on the recent data on empagliflozin in patients with acute myocardial infarction. The reader will find in this article a poignant perspective on this novel avenue for cardiovascular prevention and treatment, which greatly expands the management armamentarium of cardiovascular practitioners. Indeed, we make the case that SGLT2 inhibitors have a clearly favorable class effect, with differences between individual agents mainly suitable for personalization of care and minimization of side effects.

Exposure to serum from exclusive heated tobacco product smokers induces mTOR activation and fibrotic features in human cardiac stromal cells.

Chronic smokers have increased risk of fibrosis-related atrial fibrillation. The use of heated-tobacco products (HTPs) is increasing exponentially, and their health impact is still uncertain. We aim to investigate the effects of circulating molecules in exclusive HTP chronic smokers on the fibrotic behavior of human atrial cardiac stromal cells (CSCs). CSCs were isolated from atrial tissue of elective cardiac surgery patients, and exposed to serum lots from young healthy subjects, stratified in exclusive HTP smokers, tobacco combustion cigarette (TCC) smokers, or nonsmokers (NS). CSCs treated with TCC serum displayed impaired migration and increased expression of pro-inflammatory cytokines. Cells cultured with HTP serum showed increased levels of pro-fibrotic markers, and reduced expression of connexin-43. Both TCC and HTP sera increased collagen release and reduced secretion of angiogenic protective factors from CSCs, compared to NS serum. Paracrine support to tube-formation by endothelial cells and to viability of cardiomyocytes was significantly impaired. Treatment with sera of both smokers groups impaired H2O2/NO release balance by CSCs and reduced early phosphorylation of several pathways compared to NS serum, leading to mTOR activation. Cotreatment with rapamycin was able to reduce mTOR phosphorylation and differentiation into aSMA-positive myofibroblasts in CSCs exposed to TCC and HTP sera. In conclusion, the circulating molecules in the serum of chronic exclusive HTP smokers induce fibrotic behavior in CSCs through activation of the mTOR pathway, and reduce their beneficial paracrine effects on endothelial cells and cardiomyocytes. These results point to a potential risk for cardiac fibrosis in chronic HTP users.

Interplay between gender and pollution on the prognosis of resuscitated out-of-hospital cardiac arrest.

BACKGROUND: Differences between men and women in prognosis after sudden pre-hospital out-of-hospital cardiac arrest (OHCA) have been described in many studies, but the interplay between gender and pollution have not been characterized in detail. We aimed at appraising the interplay between gender and pollution on the prognosis of OHCA. METHODS: Details on patients with OHCA in whom return of spontaneous circulation was obtained and transferred to a large teaching hospital were obtained from the medical charts of the ambulance service and the Polish National Health Fund. Matching pollutant concentrations (PM 2.5, PM10, As, Ni, Cd, Pb) were obtained from the Polish National Environmental Protection Inspectorate. RESULTS: Details on 948 resuscitated OHCA, 325 (34.3%) of them in women, and occurring between 2018 and 2021, were retrieved. Notably, OHCA in women was associated with significantly higher daily concentrations of PM10 (23.37 [17.09, 37.04] vs. 21.92 [16.32, 29.98] µg/m3, P=0.023) and PM2.5 (16.83 [11.87, 28.24] vs. 15.27 [11.64, 22.72] µg/m3, P=0.026), as well as heightened concentrations of Cd, daily (0.32 [0.19, 0.44] vs. 0.27 [0.17, 0.40] ng/m3, P=0.027) and over 30 days (0.34 [0.20, 0.44] vs. 0.29 [0.18, 0.43] ng/m3, P=0.027). Concurrently, OHCA in females was associated with lower daily temperatures on the day of the incident (8.40 [0.20, 15.40] vs. 9.90 [1.40, 15.90] °C, P=0.042). Despite these differences, survival at 30 days and 12 months was similar in women and men (both P>0.05). CONCLUSIONS: OHCA events with successful resuscitation in women occurred in concomitance with higher daily contaminant levels, yet short-term and long-term prognosis was similar in men and women. The interplay between gender and air pollution on OHCA outcomes requires further population-based studies.

Exploring the landscape of academic retractions in medicine: a comprehensive umbrella review.

INTRODUCTION: The escalating trend of academic article retractions over the last decades raises concerns about scientific integrity, but heterogeneity in retractions and reasons for them pose a major challenge. We aimed to comprehensively overview systematic reviews focusing on retractions in the biomedical literature. EVIDENCE ACQUISITION: We abstracted salient features and bibliometric details from shortlisted articles. The Joanna Briggs Institute (JBI) Checklist for Systematic Reviews and Research Syntheses was used for validity appraisal. EVIDENCE SYNTHESIS: A total of 11 reviews were included, published between 2016 and 2023, and reporting on a total of 1851 retracted studies. Several major reasons for retractions were identified, spanning both misconduct (e.g., falsification, duplication, plagiarism) and non-misconduct issues (e.g., unreliable data, publishing problems). Correlates include author-related factors (number of authors, nationality) and journal-related factors (impact factor), with repeat offenders contributing significantly. Impacts of retractions is profound, affecting scholarly credibility, public trust, and resource utilization. CONCLUSIONS: In order to prevent retractions and amend their adverse effects, rigorous and transparent reporting standards, enhanced training in research ethics, strengthened peer review processes, and the establishment of collaborative and integrated research integrity offices are proposed.

Acute normovolemic hemodilution in cardiac surgery: rationale and design of a multicenter randomized trial

BACKGROUND: Minimizing the use of blood component can reduce known and unknown blood transfusion risks, preserve blood bank resources, and decrease healthcare costs. Red Blood Cell (RBC) transfusion is common after cardiac surgery and associated with adverse perioperative outcomes, including mortality. Acute normovolemic hemodilution (ANH) may reduce bleeding and the need for blood product transfusion after cardiac surgery. However, its blood-saving effect and impact on major outcomes remain uncertain. METHODS: This is a single-blinded, multinational, pragmatic, randomized controlled trial with a 1:1 allocation ratio conducted in Tertiary and University hospitals. The study is designed to enroll patients scheduled for elective cardiac surgery with planned cardiopulmonary bypass (CPB). Patients are randomized to receive ANH before CPB or the best available treatment without ANH. We identified an ANH volume of at least 650 mL as the critical threshold for clinically relevant benefits. Larger ANH volumes, however, are allowed and tailored to the patient's characteristics and clinical conditions. RESULTS: The primary outcome is the percentage of patients receiving RBCs transfusion from randomization until hospital discharge, which we hypothesize will be reduced from 35% to 28% with ANH. Secondary outcomes are all-cause 30-day mortality, acute kidney injury, bleeding complications, and ischemic complications. CONCLUSION: The trial is designed to determine whether ANH can safely reduce RBC transfusion after elective cardiac surgery with CPB. STUDY Registration: This trial was registered on ClinicalTrials.gov in April 2019 with the trial identification number NCT03913481.

Towards the Fifth Pillar for the Treatment of Heart Failure with Reduced Ejection Fraction: Vericiguat in Older and Complex Patients.

Heart failure with reduced ejection fraction (HFrEF) represents an emerging epidemic, particularly affecting frail, older, and multimorbid patients. Current therapy for the management of HFrEF includes four different classes of disease-modifying drugs, commonly referred to as 'four pillars', which target the neurohormonal system that is overactivated in HF and contributes to its progression. These classes of drugs include ß-blockers, inhibitors of the renin-angiotensin-aldosterone system, mineralocorticoid receptor antagonists, and sodium-glucose co-transporter-2 (SGLT2) inhibitors. Unfortunately, these agents cannot be administered as frequently as needed to older patients because of poor tolerability and comorbidities. In addition, although these drugs have dramatically increased the survival expectations of patients with HF, their residual risk of rehospitalization and death at 5 years remains considerable. Vericiguat, a soluble guanylate cyclase (sGC) stimulator, was reported to exert beneficial effects in patients with worsening HF, including older subjects, reducing the rate of both hospitalizations and deaths, with limited adverse effects and drug interaction. In this narrative review, we present the current state of art on vericiguat, with a particular focus on elderly and frail patients.

Prediction of 30-day mortality after surgery for infective endocarditis using risk scores: Insights from a European multicenter comparative validation study.

BACKGROUND: It remains unclear today whether risk scores created specifically to predict early mortality after cardiac operations for infective endocarditis (IE) outperform or not the European System for Cardiac Operative Risk Evaluation II (EuroSCORE II). METHODS: Perioperative data and outcomes from a European multicenter series of patients undergoing surgery for definite IE were retrospectively reviewed. Only the cases with known pathogen and without missing values for all considered variables were retained for analyses. A comparative validation of EuroSCORE II and 5 specific risk scores for early mortality after surgery for IE-(1) STS-IE (Society of Thoracic Surgeons for IE); (2) PALSUSE (Prosthetic valve, Age ≥70, Large intracardiac destruction, Staphylococcus spp, Urgent surgery, Sex (female), EuroSCORE ≥10); (3) ANCLA (Anemia, New York Heart Association class IV, Critical state, Large intracardiac destruction, surgery on thoracic Aorta); (4) AEPEI II (Association pour l'Étude et la Prévention de l'Endocardite Infectieuse II); (5) APORTEI (Análisis de los factores PROnósticos en el Tratamiento quirúrgico de la Endocarditis Infecciosa)-was carried out using calibration plot and receiver-operating characteristic curve analysis. Areas under the curve (AUCs) were compared 1:1 according to the Hanley-McNeil's method. The agreement between APORTEI score and EuroSCORE II of the 30-day mortality prediction after surgery was also appraised. RESULTS: A total of 1,012 patients from 5 European university-affiliated centers underwent 1,036 cardiac operations, with a 30-day mortality after surgery of 9.7%. All IE-specific risk scores considered achieved better results than EuroSCORE II in terms of calibration; AEPEI II and APORTEI score showed the best performances. Despite poor calibration, EuroSCORE II overcame in discrimination every specific risk score (AUC, 0.751 vs 0.693 or less, P = .01 or less). For a higher/lesser than 20% expected mortality, the agreement of prediction between APORTEI score and EuroSCORE II was 86%. CONCLUSION: EuroSCORE II discrimination for 30-day mortality after surgery for IE was higher than 5 established IE-specific risk scores. AEPEI II and APORTEI score showed the best results in terms of calibration.

Management of Cardiovascular Complications in Antiphospholipid Syndrome: A Narrative Review with a Focus on Older Adults.

Antiphospholipid syndrome (APS), also known as Hughes syndrome, is an acquired autoimmune and procoagulant condition that predisposes individuals to recurrent thrombotic events and obstetric complications. Central is the role of three types of antiphospholipid antibodies that target phospholipid-binding proteins: lupus anticoagulant (LAC), anti-ß2-glycoprotein I (ß2-GPI-Ab), and anti-cardiolipin (aCL). Together with clinical data, these antibodies are the diagnostic standard. However, the diagnosis of APS in older adults may be challenging and, in the diagnostic workup of thromboembolic complications, it is an underestimated etiology. The therapeutic management of APS requires distinguishing two groups with differential risks of thromboembolic complications. The standard therapy is based on low-dose aspirin in the low-risk group and vitamin K antagonists in the high-risk group. The value of direct oral anticoagulants is currently controversial. The potential role of monoclonal antibodies is investigated. For example, rituximab is currently recommended in catastrophic antiphospholipid antibody syndrome. Research is ongoing on other monoclonal antibodies, such as daratumumab and obinutuzumab. This narrative review illustrates the pathophysiological mechanisms of APS, with a particular emphasis on cardiovascular complications and their impact in older adults. This article also highlights advancements in the diagnosis, risk stratification, and management of APS.

A 25-year-long journey into interventional cardiology: looking back, and rushing forward.

Cardiovascular disease remains decade after decade a leading cause of mortality, morbidity and resource use globally as well as locally. We have had the opportunity of being involved in several iterative breakthroughs in invasive cardiovascular procedures, ranging from the advent of coronary stents to transcatheter mitral valve repair. Building up such extensive clinical and research experience, we hereby present 25 years of cardiovascular interventions at Pineta Grande Hospital and Casa di Salute S. Lucia, respectively in Castel Volturno, and S. Giuseppe Vesuviano, both in the Italian Campania region, where the same team of interventional cardiologists has managed to adopt and master several cardiovascular innovations for the benefit of thousands of patients. Our experience showcases the evolution of invasive cardiology, especially in diagnostic and therapeutic practices. Key highlights include advancements in coronary procedures, with the introduction of bare-metal stents, drug-eluting stents and drug-coated balloons, despite the setback of bioresorbable vascular scaffolds, as well as transcatheter aortic valve implantation and innovative approaches to mitral regurgitation. Furthermore, this overview scrutinizes procedural challenges, patient outcomes, and quality of life improvements, providing a rich tapestry of clinical experiences and research insights. It serves as a testament to the dynamic nature of interventional cardiology, offering a forward-looking perspective on future trends and technologies. We hope that this overview will prove an informative and insightful read for those seeking to understand the intricate journey of invasive cardiovascular care over the past decades and its trajectory into the future.

Comparative effects of different antiplatelet strategies in carriers of CYP2C19 loss-of-function alleles: a network meta-analysis.

BACKGROUND: Carriers of cytochrome 2C19 (CYP2C19) loss of function (LoF) alleles treated with clopidogrel have impaired drug metabolism resulting in reduced active metabolite levels, high platelet reactivity (HPR), and an increased risk of thrombotic events. Several alternative antiplatelet therapies have been proposed to overcome HPR in these patients, but their comparative effects remain poorly explored. METHODS: Randomized controlled trials (RCTs) comparing different oral antiplatelet therapies in carriers of CYP2C19 LoF alleles undergoing percutaneous coronary interventions (PCI) were included. A frequentist network meta-analysis was conducted to estimate mean difference (MD) or odds ratios (OR) and 95% confidence intervals (CI). The primary outcome was platelet reactivity assessed by VerifyNow and reported as P2Y12 reaction unit (PRU). The secondary outcome was the rate of HPR. Standard-dose of clopidogrel (75 mg daily) was used as reference treatment. RESULTS: A total of 12 RCTs testing 6 alternative strategies (i.e., clopidogrel 150 mg, prasugrel 3.75 mg, 5 mg, and 10 mg, ticagrelor 90 mg bid, and adjunctive cilostazol 100 mg bid) were included in the network. Compared with standard-dose clopidogrel, the greatest reduction in PRU was observed with prasugrel 10 mg (MD -127.91; 95% CI -141.04; -114.78) and ticagrelor 90 mg bid (MD -124.91; 95% CI -161.78; -88.04), followed by prasugrel 5 mg (MD -76.33; 95% CI -98.01; -54.65) and prasugrel 3.75 mg (MD -73.00; 95% CI -100.28; -45.72). Among other strategies, adjunctive cilostazol (MD-42.64; 95% CI -64.72; -20.57) and high-dose clopidogrel (MD -32.11; 95% CI -51.33; -12.90) were associated with a modest reduction in PRU compared with standard-dose clopidogrel. CONCLUSION: Among carriers of CYP2C19 LoF alleles undergoing PCI, standard-dose prasugrel or ticagrelor are most effective in reducing platelet reactivity, while double-dose clopidogrel and additional cilostazol showed modest effects. Reduced-dose of prasugrel may represent a balanced strategy to overcome HPR without a significant increase in bleeding. The clinical implications of these pharmacodynamic findings warrant further investigation.

Transcatheter Mitral Valve Repair With the MitraClip Device for Prior Mitral Valve Repair Failure: Insights From the GIOTTO-FAILS Study.

BACKGROUND: Minimally invasive mitral valve repair has a favorable risk-benefit profile in patients with significant de novo mitral regurgitation. Its role in patients with prior mitral valve repair is uncertain. We aimed to appraise the outcome of patients undergoing transcatheter edge-to-edge repair (TEER) with prior transcatheter or surgical mitral valve repair (SMVR). METHODS AND RESULTS: We queried the Italian multicenter registry on TEER with MitraClip, distinguishing naïve patients from those with prior TEER or (SMVR). Inhospital and long-term clinical/echocardiographic outcomes were appraised. The primary outcome was the occurrence of death or rehospitalization for heart failure. A total of 2238 patients were included, with 2169 (96.9%) who were naïve to any mitral intervention, 29 (1.3%) with prior TEER, and 40 (1.8%) with prior SMVR. Several significant differences were found in baseline clinical and imaging features. Respectively, device success was obtained in 2120 (97.7%), 28 (96.6%), and 38 (95.0%, P=0.261) patients; procedural success in 2080 (95.9%), 25 (86.2%), and 38 (95.0%; P=0.047); and inhospital death in 61 (2.8%), 1 (3.5%), and no (P=0.558) patients. Clinical follow-up after a mean of 14 months showed similar rates of death, cardiac death, rehospitalization, rehospitalization for heart failure, and their composite (all P>0.05). Propensity score-adjusted analysis confirmed unadjusted analysis, with lower procedural success for the prior TEER group (odds ratio, 0.28 [95% CI, 0.09-0.81]; P=0.019) but similar odds ratios and hazard ratios for all other outcomes in the naïve, TEER, and SMVR groups (all P>0.05). CONCLUSIONS: In carefully selected patients, TEER can be performed using the MitraClip device even after prior TEER or SMVR.

Comparative diagnostic accuracy of transcranial Doppler and contrast-enhanced transthoracic echocardiography for the diagnosis of patent foramen ovale and atrial septal defect.

BACKGROUND: Recognition of right-to-left shunt is crucial in the work-up of patients with suspected patent foramen ovale (PFO) or atrial septal defect (ASD). While transesophageal echocardiography (TEE) remains the gold standard diagnostic tool for the anatomic assessment of PFO/ASD, transcranial Doppler (TCD) and contrast-enhanced transthoracic echocardiogram (CE-TTE) hold the promise of providing minimally invasive yet accurate clinical details. Their comparative accuracy remains however debated. METHODS: We conducted a retrospective observational study leveraging our extensive institutional experience with systematic TCD and CE-TTE in patients with suspected PFO/ASD. Several measures of diagnostic test accuracy were computed, with point estimates and 95% confidence intervals, when applicable. RESULTS: A total of 1358 patients were included, with age 48±14 years and 772 (58%) women. Tests were performed for diagnostic purposes in 797 (58.6%) and during follow-up in 740 (54.5%). A PFO was eventually diagnosed in 1038 (77.9%) patients, and an ASD in 60 (4.5%). Agreement between TCD and CE-TTE occurred in 1309 (85.2%) cases, with TCD yielding worse findings than CE-TTE in 91 (5.9%) patients, and vice versa in 137 (8.9%), yielding a Cohen kappa of 78.6% (95% CI: 76.3-81.1%) and a highly significant P value at McNemar test (P<0.001). After dichotomization, and using TCD as benchmark, CE-TTE yielded sensitivity 96.9%, specificity 95.1%, area under the curve 92.1%, and P=0.249. Similar findings were obtained when focusing only on diagnostic tests or follow-up ones (Cohen kappa respectively 74.0% [70.2-77.1%], P<0.001 and 80.3% [76.4-84.3%], P<0.001). Notably, Valsalva was necessary to disclose the presence of shunt during TCD in 487 (31.7%) patients and during CE-TTE in 482 (31.4%) cases. Finally, performance of TCD and CE-TTE in a subset of patients eventually undergoing TTE was quite similar. CONCLUSIONS: The diagnostic accuracy of CE-TTE appears favorable, and this imaging test may identify patients who may be missed if only TCD is used to screen patients with suspected PFO/ASD. Accordingly, CE-TTE is recommended as an adjunct diagnostic modality for all patients with a high pre-test probability of PFO/ASD and right-to-left shunt.

Intraprocedural continuous saline infusion lines significantly reduce the incidence of acute kidney injury during endovascular procedures for stroke and myocardial infarction: evidence from a systematic review and meta-regression.

BACKGROUND: Contrast media used in mechanical therapies for stroke and myocardial infarction represent a significant cause of acute kidney injury (AKI) in acute medical scenarios. Although the continuous saline infusion line (CSIL) is a standard procedure to prevent thrombus formation within the catheter during neurovascular interventions of mechanical thrombectomy (MT), it is not utilized in percutaneous coronary interventions (PCI). METHODS: A systematic review of the incidence of AKI after MT for stroke treatment was performed. These data were compared with those reported in the literature regarding the incidence of AKI after PCI for acute myocardial infarction. A random-effect model meta-regression was performed to explore the effects of CSIL on AKI incidence, using clinical details as covariates. RESULTS: A total of 18 and 33 studies on MT and PCI were included, respectively, with 69,464 patients (30,138 [43.4%] for MT and 39,326 [56.6%] for PCI). The mean age was 63.6 years±5.8 with male 66.6%±12.8. Chronic kidney disease ranged 2.0-50.3%. Diabetes prevalence spanned 11.1% to 53.0%. Smoking status had a prevalence of 7.5-72.0%. Incidence of AKI proved highly variable (I2=98%, Cochrane's Q 2985), and appeared significantly lower in the MT subgroup than in the PCI subgroups (respectively 8.3% [95% confidence interval: 4.7-11.9%] vs. 14.7 [12.6-16.8%], P<0.05). Meta-regression showed that CSIL was significantly associated with a decreased incidence of AKI (OR=0.93 [1.001-1.16]; P=0.03). CONCLUSIONS: Implementation of CSIL during endovascular procedures in acute settings was associated with a significant decrease in the risk of AKI, and its safety should be routinely considered in such interventions.
