In 7213 patients with an acute coronary syndrome, the rate of major adverse cardiovascular events was not significantly lower with bivalirudin than with heparin. Post-PCI bivalirudin infusion did not reduce the risk of stent thrombosis. The most effective antithrombotic regimen for preventing ischemic complications while limiting bleeding risk in patients with an acute coronary syndrome who are undergoing invasive treatment remains unknown. 1 – 3 Two of the most commonly used antithrombotic regimens worldwide 4 , 5 are unfractionated heparin, an indirect thrombin inhibitor, with or without the concomitant use of a glycoprotein IIb/IIIa inhibitor, and bivalirudin, a direct thrombin inhibitor, with a glycoprotein IIb/IIIa inhibitor added only for periprocedural ischemic complications. Previous studies that have compared these two options among patients who were undergoing invasive treatment for an acute coronary syndrome have provided conflicting results with respect to . . .

BackgroundUnmasking the residual cardiovascular risk is a major research challenge in the attempt to reduce cardiovascular disease (CVD) morbidity and mortality. Mounting evidence suggests that a high circulating level of trimethylamine N-oxide is a new potential CVD risk factor. We performed a systematic review of the published studies to clarify the association between circulating high levels of TMAO and cardiovascular events.MethodsStudies evaluating the association between TMAO and CVD events were searched by electronic databases up to December 2018. Pooled results were expressed as risk ratio (RR) with 95% pertinent confidence interval (CI).ResultsThree studies for a total of 923 patients at high/very high CVD risk were included in our analysis. Overall, a high TMAO level was associated with both major adverse cardiovascular events (RR = 2.05; 95% CI 1.61–2.61) and all-cause mortality (RR = 3.42; 95% CI 2.27–5.15).ConclusionsOur findings support a role of high TMAO levels in predicting CVD events. High levels of TMAO may be a new CVD risk factor, potentially useful to better plan personalized CVD prevention strategies.

Transthyretin (TTR) amyloid cardiomyopathy (ATTR-CM) is a progressive disease that has emerged as a significant cause of heart failure. Advances in the understanding of ATTR-CM pathophysiology have revolutionised its therapeutic landscape over the past decade, with the development of targeted therapies that are able to improve survival and quality of life. TTR stabilizers, such as tafamidis and acoramidis, can reduce TTR instability and subsequent amyloid fibril formation. Clinical trials have demonstrated their efficacy both in improving survival and quality of life in patients with ATTR-CM. Gene-silencing therapies using small interfering RNAs (siRNAs), such as patisiran and vutrisiran, or antisense oligonucleotide inhibitors (ASOs), such as inotersen and eplontersen, serve as powerful therapeutic options by decreasing TTR production; trials on patients with ATTR-CM have been recently published or are ongoing. Novel, emerging therapies aim to enhance fibril clearance using monoclonal antibodies, such as NI006, that target amyloid deposits in the myocardium, promoting their depletion, plausibly with regression of the structural and functional impairments caused by the disease. Concurrently, advancements in diagnostic modalities have facilitated earlier detection of this disease, allowing the timely initiation of treatment with a more significant impact on patients’ survival and quality of life. Despite these strides, challenges remain, including the high cost of disease-modifying therapy and the need for response criteria to monitor treatment’s efficacy. Future directions will involve improving patients’ screening to achieve earlier diagnoses, optimising patients’ selection for disease-modifying therapy and identifying criteria for the treatment’s response or lack thereof to possibly consider therapy switch or associations. In this review, we will explore the more recent therapeutic advancements in ATTR-CM, starting from traditional heart failure therapies and moving to disease-modifying therapies with a detailed evaluation of the registration trials to explore the strengths and shortcomings of each treatment.

The study aims at investigating the impact of polymedication and aging in the prevalence of multiple drug-drug interactions (DDIs) on HCV patients treated with sofosbuvir/velpatasvir (SOF/VEL) or glecaprevir/pibrentasvir (GLE/PIB). This is a retrospective analysis based on administrative data covering around 6.9 million individuals. Patients treated with SOF/VEL or GLE/PIB over November 2017-March 2020 were included. Index date corresponded to SOF/VEL or GLE/PIB first prescription during such period; patients were followed up for treatment duration. Analyses were then focused on patients with ≥2 comedications at risk of multiple DDIs. The severity and the effect of multiple DDI were identified using the Liverpool University tool. A total of 2057 patients with SOF/VEL and 2128 with GLE/PIB were selected. Mean age of SOF/VEL patients was 58.5 years, higher than GLE/PIB ones (52.5 years) (p < 0.001), and patients >50 years were more present in SOF/VEL vs GLE/PIB cohorts: 72% vs 58%, (p < 0.001). Most prescribed co-medications were cardiovascular, alimentary and nervous system drugs. Proportion of patients with ≥2 comedications was higher in SOF/VEL compared to GLE/PIB cohort (56.5% vs 32.3%, p < 0.001). Those at high-risk of multiple DDIs accounted for 11.6% (N = 135) of SOF/VEL and 19.6% (N = 135) of GLE/PIB (p < 0.001) patients with ≥2 comedications. Among them, the potential effect of DDI was a decrease of DAA serum levels (11% of SOF/VEL and GLE/PIB patients) and an increased concentration of comedication serum levels (14% of SOF/VEL and 42% of GLE/PIB patients). This real-world analysis provided a thorough characterization on the burden of polymedication regimens in HCV patients treated with SOF/VEL or GLE/PIB that expose such patients to an increased risk of DDIs. In our sample population, SOF/VEL regimen was more frequently detected on elderly patients and on those with ≥2 comedications at risk of multi-DDI, ie, among patients characterized by higher rates of comorbidities and polypharmacy.

Experience with angiotensin-receptor neprilysin inhibitors (ARNI) in oncologic patients with heart failure (HF) is limited. We report a case of ARNI started as first-choice therapy in a patient with relapsing hairy cell leukaemia (HCL) and HF with depressed left ventricular ejection fraction (LVEF). A middle-aged male, previously treated with rituximab for HCL, was scheduled for cardiologic screening before starting a new antineoplastic therapy for cancer relapse. The patient had symptomatic HF with reduced LVEF and high NT-proBNP levels. In this patient, early ARNI treatment was well tolerated and produced a rapid and durable improvement of symptoms, LVEF and NT-proBNP levels. Consequently, the oncologic team could start an experimental treatment with obinutuzumab, with complete HCL remission. In conclusion, in this patient with HCL and HF, ARNI therapy was safe and effective, contributing to undelayed cancer treatment.

Purpose: The study aimed to analyze, in hypercholesterolemic patients under statin medication, patient characteristics and their lipid profile at baseline, the therapeutic pathway, and the pharmaco-utilization, using real-world data in Italy. Patients and Methods: A retrospective study was conducted using administrative databases of a sample of entities covering 6.5 million health-assisted individuals. Between January 2010 and June 2019, patients with non-familial hypercholesterolemia (nFH) were identified by 1) [greater than or equal to]1 low-density lipoprotein cholesterol (LDL-C) measurement (LDL-C assessment date was the index-date) and 2) statin prescription during 6 months before the index-date (pharmaco-utilization period). FH patients were defined by LDL-C evaluation, statin treatment during the pharmaco-utilization period, and a score [greater than or equal to]6 according to the Dutch Lipid Clinic Network criteria. nFH patients were divided into four exclusive cohorts based on CV-risk class: 1) with previous CV disease (CVD); 2) with diabetes mellitus; 3) with mixed-dyslipidemia diagnosis; 4) in primary-prevention. Based on LDL-C index values, patient was defined with LDL-C \"controlled\" if its levels were [less than or equal to]70mg/dl (CVD), [less than or equal to]100mg/dl (diabetes, FH), [less than or equal to]130mg/dl (mixed-dyslipidemia, primary-prevention). Results: Overall 164,161 nFH patients were included (mean age 72 years, 51% male); of these, 46,782 (28.5%) were CVD (mean age 74 years, 66% male), 34,803 (21.2%) were diabetic (mean age 72 years, 51% male), 1617 (1%) were with mixed-dyslipidemia (mean age 71 years, 48% male) and 80,959 (49.3%) were in primary-prevention (mean age 71 years, 42% male). The proportion of nFH patients with controlled LDL-C was 41.2% for CVD, 73.6% for diabetic, 80.7% for mixed-dyslipidemia, and 79.5% for primary-prevention patients; 49% of nFH patients were adherent to therapy. Overall, 1287 FH patients (mean age 64 years, 42% male) were included; in 39.2% of the patients, LDL-C was controlled, and 44% of the patients were adherent to therapy. Conclusion: The results of this study highlighted non-optimal therapeutic management of hypercholesterolemic patients in Italian clinical practice, with a notable quote of patients non-adherent to therapy.

This real-world study investigates the direct healthcare costs from the perspective of the Italian Healthcare National Service of experienced statin users according to their level of adherence to therapy and to their cardiovascular (CV) profile in Italian settings of outpatients clinical practice. A retrospective observational analysis was performed based on administrative databases covering approximately 6 million health-assisted individuals. Adult patients with statins prescription between January 2014 and December 2016 were screened, and first prescription within this period was the index date. Follow-up lasted 1 year after index date. Only patients receiving statins prior index date (experienced statin users) were included and distributed in clusters based on their CV profile. Adherence was calculated during follow-up as proportion of days covered (PDC) and classified in low adherence (PDC<40%), partial adherence (PDC=40-79%) and adherence (PDC≥80%). Mean direct healthcare costs of drugs, hospitalizations, and outpatient services were evaluated during follow-up. A total of 436,623 experienced statin users were included and distributed as follows: 5.5% in the previous CV events, 22.6% in diabetes, 55.7% in CV treatments and 16.2% in the no comorbidity cluster. Total mean annual cost/patient decreased from low adherent to adherent patients from €4826 to €3497 in previous CV events, from €2815 to €2360 in diabetes cluster, from €2077 to €1863 for patients with CV treatments. Same trend was reported for the cost item related to hospitalizations, which was the major determinant of the total costs. In previous CV event cluster, adherence was associated to a saving of €879 on total costs. The study highlighted a decrease in overall mean costs as adherence levels increase, particularly for patients with previous CV events, showing how improving adherence could be associated to cost savings and suggesting suited strategy based on CV profile should be undertaken for adherence optimization.

Several studies have already demonstrated that the incomplete polymerization of resin-based dental materials causes the release of monomers which might affect cell metabolism. The aim of this study was to investigate the effects of triethylene glycol dimethacrylate, 1,4-butanediol dimethacrylate, urethane dimethacrylate, and 2-hydroxyethyl methacrylate on (1) cellular energy metabolism, evaluating oxygen consumption rate, glucose consumption, glucose 6-phosphate dehydrogenase activity, and lactate production, and (2) cellular redox status, through the evaluation of glutathione concentration and of the activities of enzymes regulating glutathione metabolism. Methods. Human pulp cells were used and oxygen consumption was measured by means of a Clark electrode. Moreover, reactive oxygen species production was quantified. Enzymatic activity and glucose and lactate concentrations were determined through a specific kit. Results. Triethylene glycol dimethacrylate, 1,4-butanediol dimethacrylate, and 2-hydroxyethyl methacrylate induced a decrease in oxygen consumption rate, an enhancement of glucose consumption, and lactate production, whilst glucose 6-phosphate dehydrogenase and glutathione reductase activity were not significantly modified. Moreover, the monomers induced an increase of reactive oxygen species production with a consequent increase of superoxide dismutase and catalase enzymatic activities. A depletion of both reduced and total glutathione was also observed. Conclusion. The obtained results indicate that dental monomers might alter energy metabolism and glutathione redox balance in human pulp cells.

The Laser Interferometer Space Antenna (LISA) will be a transformative experiment for gravitational wave astronomy, and, as such, it will offer unique opportunities to address many key astrophysical questions in a completely novel way. The synergy with ground-based and space-born instruments in the electromagnetic domain, by enabling multi-messenger observations, will add further to the discovery potential of LISA. The next decade is crucial to prepare the astrophysical community for LISA’s first observations. This review outlines the extensive landscape of astrophysical theory, numerical simulations, and astronomical observations that are instrumental for modeling and interpreting the upcoming LISA datastream. To this aim, the current knowledge in three main source classes for LISA is reviewed; ultra-compact stellar-mass binaries, massive black hole binaries, and extreme or interme-diate mass ratio inspirals. The relevant astrophysical processes and the established modeling techniques are summarized. Likewise, open issues and gaps in our understanding of these sources are highlighted, along with an indication of how LISA could help making progress in the different areas. New research avenues that LISA itself, or its joint exploitation with upcoming studies in the electromagnetic domain, will enable, are also illustrated. Improvements in modeling and analysis approaches, such as the combination of numerical simulations and modern data science techniques, are discussed. This review is intended to be a starting point for using LISA as a new discovery tool for understanding our Universe.

Blockade of the renin-angiotensin-aldosterone system is a cornerstone in cardiovascular disease prevention and hypertension treatment. The relevance of ambulatory blood pressure monitoring (ABPM) has been widely confirmed for both increasing the accuracy of blood pressure (BP) measurements, particularly in pharmacological trials, and focusing on 24 h BP prognostic parameters. The aim of this study was to assess the effects of canrenone addition on ambulatory BP in uncontrolled hypertensive patients already treated with the highest tolerated dose of angiotensin-converting enzyme (ACE) inhibitors or angiotensin II type 1 receptor (AT1R) antagonists plus hydrochlorothiazide (HCT). ABPM was performed at baseline and after 3 months of combination therapy in 158 outpatients with stage 1 or 2 hypertension who were randomized to add canrenone (50 or 100 mg) to the pre-existing therapy with ACE inhibitors or AT1R antagonists plus HCT. Twenty-four-hour systolic and diastolic BPs were considered normalized when the values were <130 and <80 mmHg, respectively. The addition of canrenone was associated with a reduction in systolic and diastolic BPs (24 h and daytime and nighttime; <0.001), mean arterial pressures ( <0.001), and pulse pressures ( <0.01). The Δ 24 h systolic/diastolic BPs were -13.5±11.2/-8±8 mmHg and -16.1±13.5/-11.2±8.3 mmHg (50 and 100 mg/day, respectively). In the 50 mg arm, the 24 h systolic and diastolic BPs were normalized in 67.5% and 74% of the patients, respectively, and in 61.6% and 68.5% of the patients in the 100 mg arm, respectively ( <0.05; = not significant for 50 vs 100 mg). The percentage of patients whose nocturnal decrease was >10% with respect to diurnal values did not change during combination therapy. Canrenone addition to ACE inhibitors or AT1R antagonists plus HCT was associated with a significant reduction of 24 h BP and to an increased number of patients meeting 24 h ABPM targets in a clinical setting of uncontrolled stage 1 or 2 hypertension.
