Gravity sedimentation reveals functionally and morphologically different platelets in human blood. Platelets 2024; 35:2298341. [PMID: 38186228 DOI: 10.1080/09537104.2023.2298341] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Accepted: 12/16/2023] [Indexed: 01/09/2024]
Abstract
In contrast to red blood cells, platelets float rather than sediment when a column of blood is placed in the gravitational field. By the analogy of erythrocyte sedimentation (ESR), it can be expressed with the platelet antisedimentation rate (PAR), which quantitates the difference in platelet count between the upper and lower halves of the blood column after 1 h of 1 g sedimentation. Venous blood samples from 21 healthy subjects were analyzed for PAR. After a 1-h sedimentation, the upper and lower fractions of blood samples were analyzed for platelet count, mean platelet volume (MPV), immature platelet fraction (IPF), and high-fluorescence IPF (H-IPF). The mechanisms behind platelet flotation were explored by further partitioning of the blood column, time-dependent measurements of platelet count and comparison with ESR. The structure and function of the platelets were assessed by electron microscopy (EM) and atomic force microscopy (AFM), and platelet aggregometry, respectively. Platelet antisedimentation is driven by density differences and facilitated by a size-exclusion mechanism caused by progressive erythrocyte sedimentation. The area under the curve (AUC) of the whole blood adenosine diphosphate (ADP) aggregation curves showed significant differences between the upper and lower samples (p < .005). AUC in the upper samples of 38% of healthy subjects exceeded the top of the normal range (53-122) suggesting that ascending platelets show an intensified ADP-induced aggregability ex vivo. H-IPF was significantly higher in the upper samples (p < .05). EM and AFM revealed that platelets in the upper samples were larger in volume and contained 1.6 times more alpha granules compared to platelets in the lower samples. Our results indicate that antisedimentation is able to differentiate platelet populations based on their structural and functional properties. Therefore, PAR may be a suitable laboratory parameter in various thromboinflammatory disorders.

Hutchinson-Gilford progeria syndrome mice display accelerated arterial thrombus formation and increased platelet reactivity. Thromb Res 2024; 241:109100. [PMID: 39032390 DOI: 10.1016/j.thromres.2024.109100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 07/12/2024] [Accepted: 07/17/2024] [Indexed: 07/23/2024]
Abstract
INTRODUCTION Hutchinson-Gilford Progeria Syndrome (HGPS) is an ultra-rare premature aging genetic disorder caused by a point mutation in the lamin A gene, LMNA. Children with HGPS display short lifespans and typically die due to myocardial infarction or ischemic stroke, both acute cardiovascular events that are tightly linked to arterial thrombosis. Despite this fact, the effect of the classic HGPS LMNA gene mutation on arterial thrombosis remains unknown. METHODS Heterozygous LmnaG609G knock-in (LmnaG609G/+) mice, yielding an equivalent classic mutation observed in HGPS patients (c.1824C>T; pG608G mutation in the human LMNA gene) and corresponding wild-type (WT) control littermates underwent photochemically laser-induced carotid injury to trigger thrombosis. Coagulation and fibrinolytic factors were measured. Furthermore, platelet activation and reactivity were investigated. RESULTS LmnaG609G/+ mice displayed accelerated arterial thrombus formation, as underlined by shortened time to occlusion compared to WT littermates. Levels of factors involved in the coagulation and fibrinolytic system were comparable between groups, while LmnaG609G/+ animals showed higher plasma levels of thrombin-antithrombin complex and lower levels of antithrombin. Bone marrow analysis showed larger megakaryocytes in progeric mice. Lastly, enhanced platelet activation upon adenosine diphosphate, collagen-related peptide, and thrombin stimulation was observed in LmnaG609G/+ animals compared to the WT group, indicating a higher platelet reactivity in progeric animals. CONCLUSIONS LMNA mutation in HGPS mice accelerates arterial thrombus formation, which is mediated, at least in part, by enhanced platelet reactivity, which consequently augments thrombin generation. Given the wide spectrum of antiplatelet agents available clinically, further investigation is warranted to consider the most suitable antiplatelet regimen for children with HGPS to mitigate disease mortality and morbidity.

Abstract
Although immunotherapy is expanding treatment options for cancer patients, the prognosis of advanced cancer remains poor, and these patients must contend with both cancers and cancer-related thrombotic events. In particular, immune checkpoint inhibitors are associated with an increased risk of atherosclerotic thrombotic events. Given the fundamental role of platelets in atherothrombosis, co-administration of antiplatelet agents is always indicated. Platelets are also involved in all steps of cancer progression. Classical antithrombotic drugs can cause inevitable hemorrhagic side effects due to blocking integrin β3 bidirectional signaling, which regulates simultaneously thrombosis and hemostasis. Meanwhile, many promising new targets are emerging with minimal bleeding risk and desirable anti-tumor effects. This review will focus on the issue of thrombosis during immune checkpoint inhibitor treatment and the role of platelet activation in cancer progression as well as explore the mechanisms by which novel antiplatelet therapies may exert both antithrombotic and antitumor effects without excessive bleeding risk.

Abstract
BACKGROUND Metabolic clusters can stratify subgroups of individuals at risk for type 2 diabetes mellitus and related complications. Since obesity and insulin resistance are closely linked to alterations in hemostasis, we investigated the association between plasmatic coagulation and metabolic clusters including the impact on survival. METHODS Utilizing data from the Ludwigshafen Risk and Cardiovascular Health (LURIC) study, we assigned 917 participants without diabetes to prediabetes clusters, using oGTT-derived glucose and insulin, high-density lipoprotein cholesterol, triglycerides, and anthropometric data. We performed a comprehensive analysis of plasmatic coagulation parameters and analyzed their associations with mortality using proportional hazards models. Mediation analysis was performed to assess the effect of coagulation factors on all-cause mortality in prediabetes clusters. RESULTS Prediabetes clusters were assigned using published tools, and grouped into low-risk (clusters 1,2,4; n = 643) and high-risk (clusters 3,5,6; n = 274) clusters. Individuals in the high-risk clusters had a significantly increased risk of death (HR = 1.30; CI: 1.01 to 1.67) and showed significantly elevated levels of procoagulant factors (fibrinogen, FVII/VIII/IX), D-dimers, von-Willebrand factor, and PAI-1, compared to individuals in the low-risk clusters. In proportional hazards models adjusted for relevant confounders, elevated levels of fibrinogen, D-dimers, FVIII, and vWF were found to be associated with an increased risk of death. Multiple mediation analysis indicated that vWF significantly mediates the cluster-specific risk of death. CONCLUSIONS High-risk prediabetes clusters are associated with prothrombotic changes in the coagulation system that likely contribute to the increased mortality in those individuals at cardiometabolic risk. The hypercoagulable state observed in the high-risk clusters indicates an increased risk for cardiovascular and thrombotic diseases that should be considered in future risk stratification and therapeutic strategies.

Abstract
Efficient tumor-targeted drug delivery is still a challenging and currently unbreakable bottleneck in chemotherapy for tumors. Nanomedicines based on passive or active targeting strategy have not yet achieved convincing chemotherapeutic benefits in the clinic due to the tumor heterogeneity. Inspired by the efficient inflammatory-cell recruitment to acute clots, we constructed a two-component nanosystem, which is composed of an RGD-modified pyropheophorbide-a (Ppa) micelle (PPRM) that mediates the tumor vascular-targeted photodynamic reaction to activate local coagulation and subsequently transmits the coagulation signals to the circulating clot-targeted CREKA peptide-modified camptothecin (CPT)-loaded nanodiscs (CCNDs) for amplifying tumor targeting. PPRM could effectively bind with the tumor vasculature and induce sufficient local thrombus by a photodynamic reaction. Local photodynamic reaction-induced tumor target amplification greatly increased the tumor accumulation of CCND by 4.2 times, thus significantly enhancing the chemotherapeutic efficacy in the 4T1 breast tumor model. In other words, this study provides a powerful platform to amplify tumor-specific drug delivery by taking advantage of the efficient crosstalk between the PPRM-activated coagulation cascade and clot-targeted CCND.

Abstract
Direct oral anticoagulants (DOACs) have largely replaced vitamin K antagonists, mostly warfarin, for the main indications for oral anticoagulation, prevention and treatment of venous thromboembolism, and prevention of embolic stroke in atrial fibrillation. While DOACs offer practical, fixed-dose anticoagulation in many patients, specific restrictions or contraindications may apply. DOACs are not sufficiently effective in high-thrombotic risk conditions such as antiphospholipid syndrome and mechanical heart valves. Patients with cancer-associated thrombosis may benefit from DOACs, but the bleeding risk, particularly in those with gastrointestinal or urogenital tumors, must be carefully weighed. In patients with frailty, excess body weight, and/or moderate-to-severe chronic kidney disease, DOACs must be cautiously administered and may require laboratory monitoring. Reversal agents have been developed and approved for life-threatening bleeding. In addition, the clinical testing of potentially safer anticoagulants such as factor XI(a) inhibitors is important to further optimize anticoagulant therapy in an increasingly elderly and frail population worldwide.

Abstract
The prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) continues to rise, making it one of the most prevalent chronic liver disorders. MASLD encompasses a range of liver pathologies, from simple steatosis to metabolic dysfunction-associated steatohepatitis (MASH) with inflammation, hepatocyte damage, and fibrosis. Interestingly, the liver exhibits close intercommunication with fatty tissue. In fact, adipose tissue could contribute to the etiology and advancement of MASLD, acting as an endocrine organ that releases several hormones and cytokines, with the adipokines assuming a pivotal role. The levels of adipokines in the blood are altered in people with MASLD, and recent research has shed light on the crucial role played by adipokines in regulating energy expenditure, inflammation, and fibrosis in MASLD. However, MASLD disease is a multifaceted condition that affects various aspects of health beyond liver function, including its impact on hemostasis. The alterations in coagulation mechanisms and endothelial and platelet functions may play a role in the increased vulnerability and severity of MASLD. Therefore, more attention is being given to imbalanced adipokines as causative agents in causing disturbances in hemostasis in MASLD. Metabolic inflammation and hepatic injury are fundamental components of MASLD, and the interrelation between these biological components and the hemostasis pathway is delineated by reciprocal influences, as well as the induction of alterations. Adipokines have the potential to serve as the shared elements within this complex interrelationship. The objective of this review is to thoroughly examine the existing scientific knowledge on the impairment of hemostasis in MASLD and its connection with adipokines, with the aim of enhancing our comprehension of the disease.

Abstract
BACKGROUND Establishing the appropriate rivaroxaban dose in older patients with non-valvular atrial fibrillation (NVAF) is important because of the high risk of adverse events. In this EXPAND study subanalysis, we examined the safety and efficacy of standard-dose (15 mg/day) and non-recommended reduced-dose (10 mg/day) rivaroxaban in patients aged ≥65 years with NVAF and preserved renal function. METHODS The entire analysis population (ALL cohort [n = 3982]; ≥65 years) was divided into early elderly (ELD) (65-74 years [n = 1444]) and late ELD (≥75 years [n = 2386]) sub-cohorts. Each sub-cohort was divided into reduced-dose and standard-dose groups. Kaplan-Meier survival curves with adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) were used to assess efficacy (thromboembolic events) and safety (hemorrhagic events) outcomes. RESULTS The aHR for major bleeding did not differ between the dosages in any of the cohorts (aHRs: 0.86-0.93). There were no significant differences in the occurrence of stroke + systemic embolism (SE) or stroke + SE + myocardial infarction (MI) + cardiovascular (CV) death among the cohorts. The aHR for MI/unstable angina + interventional/CV surgery + CV death was higher with 10-mg/day rivaroxaban than 15-mg/day rivaroxaban in the ALL cohort (aHR: 1.56 [95% CI 1.02-2.37], p = 0.039) and the late ELD sub-cohort (aHR: 1.86 [95% CI 1.01-3.42], p = 0.045). CONCLUSIONS Reduced-dose rivaroxaban may increase the risk of coronary artery events. The use of rivaroxaban 15 mg/day in patients with NVAF aged ≥75 years with preserved renal function was supported.

Abstract
Significance: Several aging-related pathophysiological mechanisms have been described to contribute to increased thrombotic risk in the elderly, including oxidative stress, endothelial dysfunction, and platelet and coagulation cascade activation. Antithrombotic treatment in the elderly should be individualized. Recent Advances: Recent studies have clarified some pathophysiological mechanisms of enhanced oxidative stress and thrombotic alterations in older adults. In the last decade, randomized trials have evaluated different antithrombotic strategies to reduce the risk of cardiovascular events in these patients. Critical Issues: The proportion of elderly patients included in clinical trials is generally low, thus not reflecting the daily clinical practice. There is no consensus on the most appropriate antithrombotic treatment in the elderly, also considering that bleeding risk management may be challenging in this high-risk subgroup of patients. Routine antiplatelet treatment is not a valid strategy for the primary prevention of cardiovascular events given the associated high risk of bleeding. In elderly patients with acute coronary syndrome, low-dose prasugrel or clopidogrel, shorter dual antiplatelet therapy, and no pretreatment before stent placement should be considered. Advanced age should not be the only reason for the underuse of oral anticoagulation in patients with atrial fibrillation, with direct oral anticoagulants preferred over warfarin for stroke prevention. Instead, a case-by-case clinical evaluation is warranted based on patient's bleeding risk also. Future Directions: There is a need for a structured tailored approach to manage thrombotic risk in elderly patients. The choice of the most appropriate antithrombotic treatment should balance efficacy and safety to reduce the risk of bleeding.

Abstract
INTRODUCTION Arterial thrombosis is the main underlying mechanism of acute atherothrombosis. Combined antiplatelet and anticoagulant regimens prevent thrombosis but increase bleeding rates. Mast cell-derived heparin proteoglycans have local antithrombotic properties, and their semisynthetic dual AntiPlatelet and AntiCoagulant (APAC) mimetic may provide a new efficacious and safe tool for arterial thrombosis. We investigated the in vivo impact of intravenous APAC (0.3-0.5 mg/kg; doses chosen according to pharmacokinetic studies) in two mouse models of arterial thrombosis and the in vitro actions in mouse platelets and plasma. MATERIALS AND METHODS Platelet function and coagulation were studied with light transmission aggregometry and clotting times. Carotid arterial thrombosis was induced either by photochemical injury or surgically exposing vascular collagen after infusion of APAC, UFH or vehicle. Time to occlusion, targeting of APAC to the vascular injury site and platelet deposition on these sites were assessed by intra-vital imaging. Tissue factor activity (TF) of the carotid artery and in plasma was captured. RESULTS APAC inhibited platelet responsiveness to agonist stimulation (collagen and ADP) and prolonged APTT and thrombin time. After photochemical carotid injury, APAC-treatment prolonged times to occlusion in comparison with UFH or vehicle, and decreased TF both in carotid lysates and plasma. Upon binding from circulation to vascular collagen-exposing injury sites, APAC reduced the in situ platelet deposition. CONCLUSIONS Intravenous APAC targets arterial injury sites to exert local dual antiplatelet and anticoagulant actions and attenuates thrombosis upon carotid injuries in mice. Systemic APAC provides local efficacy, highlighting APAC as a novel antithrombotic to reduce cardiovascular complications.

Abstract
The vascular extracellular matrix (ECM) produced by endothelial and smooth muscle cells is composed of collagens and glycoproteins and plays an integral role in regulating the structure and function of the vascular wall. Alteration in the expression of these proteins is associated with endothelial dysfunction and has been implicated in the development and progression of atherosclerosis. The ECM composition of atherosclerotic plaques varies depending on plaque phenotype and vulnerability, with distinct differences observed between ruptured and erodes plaques. Moreover, the thrombi on the exposed ECM are diverse in structure and composition, suggesting that the best antithrombotic approach may differ depending on plaque phenotype. This review provides a comprehensive overview of the role of proteoglycans in atherogenesis and thrombosis. It discusses the differential expression of the proteoglycans in different plaque phenotypes and the potential impact on platelet function and thrombosis. Finally, the review highlights the importance of this concept in developing a targeted approach to antithrombotic treatments to improve clinical outcomes in cardiovascular disease.

Abstract
Chronic inflammation contributes to the pathogenesis of many diseases, including apparently unrelated conditions such as metabolic disorders, cardiovascular diseases, neurodegenerative diseases, osteoporosis, and tumors, but the use of conventional anti-inflammatory drugs to treat these diseases is generally not very effective given their adverse effects. In addition, some alternative anti-inflammatory medications, such as many natural compounds, have scarce solubility and stability, which are associated with low bioavailability. Therefore, encapsulation within nanoparticles (NPs) may represent an effective strategy to enhance the pharmacological properties of these bioactive molecules, and poly lactic-co-glycolic acid (PLGA) NPs have been widely used because of their high biocompatibility and biodegradability and possibility to finely tune erosion time, hydrophilic/hydrophobic nature, and mechanical properties by acting on the polymer's composition and preparation technique. Many studies have been focused on the use of PLGA-NPs to deliver immunosuppressive treatments for autoimmune and allergic diseases or to elicit protective immune responses, such as in vaccination and cancer immunotherapy. By contrast, this review is focused on the use of PLGA NPs in preclinical in vivo models of other diseases in which a key role is played by chronic inflammation or unbalance between the protective and reparative phases of inflammation, with a particular focus on intestinal bowel disease; cardiovascular, neurodegenerative, osteoarticular, and ocular diseases; and wound healing.

Abstract
The article is devoted to an urgent problem - primary and secondary prevention of atherosclerotic cardiovascular diseases. Modern approaches to management tactics depending on age and the appointment of antiplatelet therapy with acetylsalicylic acid in low doses from 75 to 150 mg/day are presented. At the same time, the relatively high effectiveness of the use of ASA for primary prevention in men 40-69 years old without an increased risk of bleeding from the gastrointestinal tract is shown. Low doses of ASA provide little benefit in reducing the risk of CVD in people 40 years and older, when there is no history of CVD, but at the same time they are at increased risk of CVD.

Abstract
Peripheral artery disease (PAD) is a clinical manifestation of atherosclerotic disease with a large-scale impact on the economy and global health. Despite the role played by platelets in the process of atherogenesis being well recognized, evidence has been increasing on the contribution of the coagulation system to the atherosclerosis formation and PAD development, with important repercussions for the therapeutic approach. Histopathological analysis and some clinical studies conducted on atherosclerotic plaques testify to the existence of different types of plaques. Likely, the role of coagulation in each specific type of plaque can be an important determinant in the histopathological composition of atherosclerosis and in its future stability. In this review, we analyze the molecular contribution of inflammation and the coagulation system on PAD pathogenesis, focusing on molecular similarities and differences between atherogenesis in PAD and coronary artery disease (CAD) and discussing the possible implications for current therapeutic strategies and future perspectives accounting for molecular inflammatory and coagulation targets. Understanding the role of cross-talking between coagulation and inflammation in atherosclerosis genesis and progression could help in choosing the right patients for future dual pathway inhibition strategies, where an antiplatelet agent is combined with an anticoagulant, whose role, despite pathophysiological premises and trials' results, is still under debate.

Abstract
Obesity, a burgeoning worldwide health system challenge, is associated with several comorbidities, including non-alcoholic fatty liver disease (NAFLD), diabetes, atherosclerosis, and osteoarthritis, leading to serious problems to people's health. Adenosine is a critical extracellular signaling molecule that has essential functions in regulating most organ systems by binding to four G-protein-coupled adenosine receptors, denoted A1 , A2A , A2B , and A3 . Among the receptors, a growing body evidence highlights the key roles of the adenosine 2A receptor (A2A R) in obesity and related diseases. In the current review, we summarize the effects of A2A R in obesity and obesity-associated non-alcoholic fatty liver disease, diabetes, atherosclerosis, and osteoarthritis, to clarify the complicated impacts of A2A R on obesity and related diseases.

Abstract
Objective The current study was undertaken to prospectively explore whether having low levels of von Willebrand factor (vWF) antigen and vWF activity reduce the risk for cardiovascular disease and death. Methods VWF antigen and vWF activity were measured by enzyme-linked immunosorbent assay and an immunological-based assay, respectively, in a subsample of 4857 individuals aged between 35 and 74 years old, enrolled between April 2007 and October 2008 in the population-based Gutenberg Health Study. VWF antigen and activity below the 20th percentile was set as a measure of "low vWF." Adjusted robust Poisson regression models were used to analyze the relation between low vWF and the incidence of cardiovascular disease (CVD). Consequent adjusted cox regression models as well as cumulative incidence plots were calculated to explore the relation between all-cause and cardiovascular mortality and low vWF. Results VWF activity levels <20th percentile (i.e., <76.2%) were associated with a decreased relative risk for CVD (RR: 0.59, 95% CI: 0.37-0.95), despite adjusting for age and sex. After adjusting for levels of F-VIII, the association persisted (RR: 0.60, 95% CI: 0.36-0.99). The cumulative incidence plots demonstrated that vWF antigen <20th percentile significantly correlated with decreased cardiovascular mortality. VWF antigen<20th percentile (i.e., <83%) was significantly associated with lower risk of all-cause mortality, despite adjusting for clinical factors (RR: 61, 95% CI: 0.41-0.91). Conclusion The study demonstrated that having low vWF activity levels were associated with a lower risk for CVD. Additionally, it revealed a decreased risk of cardiovascular and all-cause mortality in individuals with low levels of vWF antigen, shining new light on vWF as a potential target for novel therapies.

Abstract
Cardiovascular diseases represent the leading cause of mortality worldwide, with recent epidemiological studies revealing an increasing trend of prevalence and incidence globally. Among cardiovascular disorders, both arterial and venous thrombosis and particularly their acute life-threating complications such as ischemic stroke, acute myocardial infarction, deep venous thrombosis and pulmonary embolism are responsible for more than 25% of all deaths worldwide. The modern approach following progresses in anticoagulant, thrombolytic and antiaggregant therapies has significantly improved the prognoses of these conditions in the last past decades. However, several challenges still remain such as achieving the optimal drug concentration at the injured site, reducing the shortcomings of drug resistance and the incidence of life-threatening hemorrhages. Nanomedicine is a well-known field of medicine in which atomic and molecular structures ranging between 0.1–100 nm are used in various domains due to their specific mechanical, electrical, thermal and magnetic properties. Recent experimental and clinical evidence have shown that nanotechnology could be a safe, effective and an appealing approach for various non-cardiovascular and cardiovascular diseases such as thromboembolic conditions. In this review, we have described the most promising nanotechnology-based approaches not only for the diagnosis, but also for the treatment of vascular thrombotic diseases.

Abstract
Background Among patients with atrial fibrillation and stable coronary artery disease, those with histories of atherothrombotic disease are at high-risk for future ischemic events. This study investigated the efficacy and safety of rivaroxaban monotherapy in patients with atrial fibrillation, coronary artery disease, and histories of atherothrombotic disease. Methods and Results This was a post hoc subanalysis of the AFIRE (Atrial Fibrillation and Ischemic Events With Rivaroxaban in Patients With Stable Coronary Artery Disease) trial. Patients with non-valvular atrial fibrillation and coronary artery disease were recruited and randomized to receive the rivaroxaban monotherapy or combination therapy with rivaroxaban plus antiplatelet drug. For the purpose of this sub-study, participants were divided into 2 subgroups, including the atherothrombosis group (those with histories of myocardial infarction, stroke, and/or peripheral artery disease; n=1052, 47.5%) and non-atherothrombosis group (n=1163, 52.5%). The efficacy end point included cardiovascular events or all-cause death, while the safety end point was major bleeding. Net adverse events consisted of all-cause death, myocardial infarction, stroke, or major bleeding. In the atherothrombosis group, rivaroxaban monotherapy was significantly associated with a lower risk of net adverse events when compared with combination therapy (hazard ratio [HR], 0.50; 95% CI, 0.34-0.74; P<0.001), with a decrease in both efficacy (HR, 0.68; 95% CI, 0.47-0.99; P=0.044) and safety (HR, 0.37; 95% CI, 0.19-0.71; P=0.003) end points. By contrast, there were no differences between treatment outcomes for the non-atherothrombosis group. Conclusions Rivaroxaban monotherapy significantly reduced net adverse events as compared with combination therapy for patients with atrial fibrillation, coronary artery disease, and prior atherothrombotic disease.

Current Therapeutic Approach to Acute Myocardial Infarction in Patients with Congenital Hemophilia. Life (Basel) 2021; 11:1072. [PMID: 34685443 PMCID: PMC8537181 DOI: 10.3390/life11101072] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Revised: 10/07/2021] [Accepted: 10/09/2021] [Indexed: 12/22/2022] Open
Abstract
Advances in the treatment of hemophilia have made the life expectancy of hemophiliacs similar to that of the general population. Physicians have begun to face age-related diseases not previously encountered in individuals with hemophilia. Treatment of acute myocardial infarction (AMI) is particularly challenging because the therapeutic strategies influence both the patient's thrombotic and hemorrhagic risk. As progress has been made in the treatment of AMI over the last decade, we performed an in-depth analysis of the available literature, highlighting the latest advances in the therapy of AMI in hemophiliacs. It is generally accepted that after the optimal substitution therapy has been provided, patients with hemophilia should be treated in the same way as those in the general population. New-generation stents that allow short dual antiplatelet therapy and potent P2Y12 receptor inhibitors have begun to be successfully used. At a time when specific recommendations and relevant data are scarce, our study provides up-to-date information to physicians involved in the treatment of AMI in hemophiliacs.

Abstract
Background
3F7 is a monoclonal antibody targeting the enzymatic pocket of activated factor XII (FXIIa), thereby inhibiting its catalytic activity. Given the emerging role of FXIIa in promoting thromboinflammation, along with its apparent redundancy for hemostasis, the selective inhibition of FXIIa represents a novel and highly attractive approach targeting pathogenic processes that cause thromboinflammation-driven cardiovascular diseases.
Methods
The effects of FXIIa inhibition were investigated using three distinct mouse models of cardiovascular disease—angiotensin II-induced abdominal aortic aneurysm (AAA), an ApoE
−/−
model of atherosclerosis, and a tandem stenosis model of atherosclerotic plaque instability. 3F7 or its isotype control, BM4, was administered to mice (10 mg/kg) on alternate days for 4 to 8 weeks, depending on the experimental model. Mice were examined for the development and size of AAAs, or the burden and instability of atherosclerosis and associated markers of inflammation.
Results
Inhibition of FXIIa resulted in a reduced incidence of larger AAAs, with less acute aortic ruptures and an associated fibro-protective phenotype. FXIIa inhibition also decreased stable atherosclerotic plaque burden and achieved plaque stabilization associated with increased deposition of fibrous structures, a >2-fold thicker fibrous cap, increased cap-to-core ratio, and reduction in localized and systemic inflammatory markers.
Conclusion
Inhibition of FXIIa attenuates disease severity across three mouse models of thromboinflammation-driven cardiovascular diseases. Specifically, the FXIIa-inhibiting monoclonal antibody 3F7 reduces AAA severity, inhibits the development of atherosclerosis, and stabilizes vulnerable plaques. Ultimately, clinical trials in patients with cardiovascular diseases such as AAA and atherosclerosis are warranted to demonstrate the therapeutic potential of FXIIa inhibition.

Abstract
The article is devoted to an urgent medical and social problem - secondary prevention of atherothrombotic stroke and contains current evidence on the use of combined antiplatelet and anticoagulant therapy. In the COMPASS study, the dual-pathway thrombosis inhibition scheme using rivaroxaban in combination with acetylsalicylic acid (ASA) compared with ASA monotherapy demonstrated in patients with established atherosclerotic diseases of the circulatory system, a decrease in the total risk of stroke, death from cardiovascular causes and myocardial infarction by 24%; reduced risk of recurrent stroke by 67%. The incidence of repeated ischemic stroke (IS) in the combination therapy group was 1.1% per year, in the ASA group - 3.4% per year. The total incidence of adverse outcomes included in the combined indicator «net clinical benefit» in the rivaroxaban group in combination with ASA was 20% lower than in the ASA group and confirms the advantages of combination therapy in the prevention of recurrent noncardioembolic IS.

Abstract
Несмотря на широкое внедрение в клиническую практику современной антитромботической стратегии (моно- или двойной антитромбоцитарной терапии), резидуальный риск неблагоприятных сердечно-сосудистых событий у пациентов с ишемической болезнью сердца (ИБС) и заболеваниями периферических артерий (ЗПА) по-прежнему остается высоким. До настоящего времени двойная антитромбоцитарная терапия является «золотым стандартом» вторичной профилактики при остром коронарном синдроме (ОКС), а монотерапия рекомендована пациентам с симптоматическим течением ЗПА, стабильной ИБС и цереброваскулярной болезнью. Вместе с тем разрыв атеросклеротической бляшки приводит не только к активации тромбоцитов, но также, вследствие экспозиции тканевого фактора, потенцирует образование тромбина. Поэтому терапевтическая стратегия, направленная на одновременное подавление генерации тромбина и активации тромбоцитов и называемая «двойной путь ингибирования», представляется более эффективной, чем известные варианты лечения, связанные с торможением только одного из двух путей. Как показали результаты исследования COMPASS, комбинация 2,5 мг ривароксабана дважды в сутки со 100 мг/сутки аспирина оказалась более эффективной по сравнению с монотерапией 100 мг/сутки аспирина в части снижения риска серьезных сердечно-сосудистых событий, незапланированных госпитализаций и летальности без увеличения количества фатальных и интракраниальных геморрагических осложнений. Преимущества режима двойного ингибирования, апробированного в исследовании COMPASS, были продемонстрированы в популяции пациентов с недавним ОКС, стабильной ИБС и ЗПА, а также после реваскуляризации нижних конечностей. На сегодняшний день ривароксабан является единственным антикоагулянтом, подтвердившим безусловные преимущества в сочетании с антитромбоцитарной терапией в указанных группах пациентов. Комбинированная терапия низкими дозами ривароксабана (2,5 мг/дважды/сутки) и аспирином (100 мг/сутки) уже включена в последние международные рекомендации как вариант вторичной профилактики у пациентов с патологией коронарных и периферических артерий.
Patients with cardiovascular (CV) disease are at high residual risk of CV events (including peripheral ischemic events), even when they receive the current antithrombotic strategies (single/dual antiplatelet therapy). Until now, dual antiplatelet therapy is the standard of care for the secondary prevention in patients with acute coronary syndrome (ACS), whereas the single antiplatelet therapy, generally with aspirin, is the standard of care for the secondary prevention in stable patients with coronary artery disease (CAD), peripheral artery disease (PAD), or cerebrovascular disease. Meanwhile, atherosclerotic plaque disruption not only induces the platelet activation, but also results in thrombin generation because of tissue factor exposure. Therefore, interrupting both pathways by combining antiplatelet therapy with an anticoagulant (dual pathway inhibition [DPI]), has the potential to be more effective than inhibiting either pathway alone. The COMPASS trial showed that in comparison with aspirin 100 mg, rivaroxaban 2.5 mg twice a day plus aspirin 100 mg reduced the risk of major cardiac events, CV hospitalization, and mortality, without the increase of intracranial or fatal bleedings. The benefit of DPI using the COMPASS regimen was demonstrated in patients with the recent ACS, in chronic CAD and PAD patients, and after the lower extremity revascularization. So far, rivaroxaban is the only anticoagulant, which is effective in combination with antiplatelet therapies in the mentioned groups. The combination of low-dose rivaroxaban (2.5 mg twice daily) and aspirin (100 mg once daily) has been included recently into the latest international recommendations for the secondary prevention in patients with coronary or peripheral artery disease.

Exogenous Integrin αIIbβ3 Inhibitors Revisited: Past, Present and Future Applications. Int J Mol Sci 2021; 22:ijms22073366.

Abstract
The integrin αIIbβ3 is the most abundant integrin on platelets. Upon platelet activation, the integrin changes its conformation (inside-out signalling) and outside-in signalling takes place leading to platelet spreading, platelet aggregation and thrombus formation. Bloodsucking parasites such as mosquitoes, leeches and ticks express anticoagulant and antiplatelet proteins, which represent major sources of lead compounds for the development of useful therapeutic agents for the treatment of haemostatic disorders or cardiovascular diseases. In addition to hematophagous parasites, snakes also possess anticoagulant and antiplatelet proteins in their salivary glands. Two snake venom proteins have been developed into two antiplatelet drugs that are currently used in the clinic. The group of proteins discussed in this review are disintegrins, low molecular weight integrin-binding cysteine-rich proteins, found in snakes, ticks, leeches, worms and horseflies. Finally, we highlight various oral antagonists, which have been tested in clinical trials but were discontinued due to an increase in mortality. No new αIIbβ3 inhibitors are developed since the approval of current platelet antagonists, and structure-function analysis of exogenous disintegrins could help find platelet antagonists with fewer adverse side effects.

Abstract
Major cardiovascular (CV) events often complicate the natural history of apparently stable atherothrombotic cardiovascular disease (CVD) despite appropriate guideline-based preventive treatment. This finding has been termed residual risk and it has been the focus of recent investigation. New and revisited targets to tackle this so-called residual risk have been proposed, including antithrombotic treatment intensification, further lowering targets of low-density lipoprotein (LDL) cholesterol, novel oral antidiabetic agents with a CV benefit, and drugs to reduce systemic inflammation. In this narrative review, we discuss the evidence, mechanisms and gaps in knowledge concerning the vascular protection derived from low-dose (2.5 mg twice daily) rivaroxaban. On this topic, the main trials (ATLAS ACS 2-TIMI 51, COMPASS and VOYAGER PAD), will be summarized in a comprehensive manner. Indeed, these have shown that a drug developed to prevent thrombus formation (selective Factor Xa inhibition) reduced events that were traditionally platelet-related in concept. Moreover, we propose a simple evidence-based clinically oriented algorithm to thoroughly identify patients at increased risk and who may benefit from this strategy in different clinical scenarios. Low-dose rivaroxaban portrays a novel promising era in atherothrombotic CVD prevention, providing a mechanistic protection beyond traditional strategies in patients overwhelmed by recurrent dismal events.

Abstract
Essentials Striated muscle myosins can promote prothrombin activation by FXa or FVa inactivation by APC. Cardiac myosin and skeletal muscle myosin are pro-hemostatic in murine tail cut bleeding models. Infused cardiac myosin exacerbates myocardial injury caused by myocardial ischemia reperfusion. Skeletal muscle myosin isoforms that circulate in human plasma can be grouped into 3 phenotypes. ABSTRACT: Two striated muscle myosins, namely skeletal muscle myosin (SkM) and cardiac myosin (CM), may potentially contribute to physiologic mechanisms for regulation of thrombosis and hemostasis. Thrombin is generated from activation of prothrombin by the prothrombinase (IIase) complex comprising factor Xa, factor Va, and Ca++ ions located on surfaces where these factors are assembled. We discovered that SkM and CM, which are abundant motor proteins in skeletal and cardiac muscles, can provide a surface for thrombin generation by the prothrombinase complex without any apparent requirement for phosphatidylserine or lipids. These myosins can also provide a surface that supports the inactivation of factor Va by activated protein C/protein S, resulting in negative feedback downregulation of thrombin generation. Although the physiologic significance of these reactions remains to be established for humans, substantive insights may be gleaned from murine studies. In mice, exogenously infused SkM and CM can promote hemostasis as they are capable of reducing tail cut bleeding. In a murine myocardial ischemia-reperfusion injury model, exogenously infused CM exacerbates myocardial infarction damage. Studies of human plasmas show that SkM antigen isoforms of different MWs circulate in human plasma, and they can be used to identify three plasma SkM phenotypes. A pilot clinical study showed that one SkM isoform pattern appeared to be linked to isolated pulmonary embolism. These discoveries enable multiple preclinical and clinical studies of SkM and CM, which should provide novel mechanistic insights with potential translational relevance for the roles of CM and SkM in the pathobiology of hemostasis and thrombosis.

Abstract
Rivaroxaban (RVX) was suggested to possess anti-inflammatory and vascular tone modulatory effects. The goal of this study was to investigate whether RVX impacts lipopolysaccharide (LPS)-induced acute vascular inflammatory response. Male rats were treated with 5 mg/kg RVX (oral gavage) followed by 10 mg/kg LPS i.p injection. Circulating levels of IL-6, MCP-1, VCAM-1, and ICAM-1 were measured in plasma 6 and 24 hours after LPS injection, while isolated aorta was used for gene expression analysis, immunohistochemistry, and vascular tone evaluation. RVX pre-treatment significantly reduced LPS mediated increase after 6h and 24h for IL-6 (4.4±2.2 and 2.8±1.7 fold), MCP-1 (1.4±1.5 and 1.3±1.4 fold) VCAM-1 (1.8±2.0 and 1.7±2.1 fold). A similar trend was observed in the aorta for iNOS (5.5±3.3 and 3.3±1.9 folds reduction, P<0.01 and P<0.001, respectively), VCAM-1 (1.3±1.2 and 1.4±1.3 fold reduction, P<0.05), and MCP-1 (3.9±2.2 and 1.9±1.6 fold reduction, P<0.01). Moreover, RVX pre-treatment, improved LPS-induced PE contractile dysfunction in aortic rings (Control vs LPS, Emax reduction = 35.4 and 31.19%, P<0.001; Control vs LPS+RVX, Emax reduction = 10.83 and 11.48%, P>0.05, respectively), resulting in 24.5% and 19.7% change in maximal constriction in LPS and LPS+RVX respectively. These data indicate that RVX pre-treatment attenuates LPS-induced acute vascular inflammation and contractile dysfunction.

Evaluation of Anti-Inflammatory, Anti-Platelet and Anti-Oxidant Activity of Wine Extracts Prepared from Ten Different Grape Varieties. Molecules 2020; 25:E5054.

Abstract
Inflammation, thrombosis and oxidative stress are rarely studied together when wine's biological activity is concerned; hence the existing literature lacks a holistic point of view in the biological outcome. The scope of the present study is to parallel evaluate the effect of wine extracts on those mechanisms. Ten wine varieties and two different extraction methods were used leading to five extracts for each wine: total lipids (TL) and fractions with different phenolic compound classes (FI, FII, FIII and FIV). Their effect on oxidative stress, platelet aggregation and the secretion of cytokines from mononuclear cells was measured and a biological score was calculated. FII of white wines is the most potent extract and the extracts FIII and TL are following. Specifically, FII had higher anti-oxidant and anti-inflammatory score while all three fractions had a similar anti-platelet score. Furthermore, FII and FIII extracts were the most potent red wine extracts and revealed the highest anti-oxidant and anti-inflammatory scores. White wine FII extracts were more potent than the red wine ones while FI and FIV extracts of red wine were more potent than the white wine ones. In conclusion, the protective effect of a wine is independent of its color but is strongly associated with its microconstituents profile. FII extract revealed the highest biological score and further examination is needed in order to identify the compounds that are responsible for the aforementioned actions.

Abstract
Coronary artery disease (CAD) is a major and common disease that poses a threat to human health. Recent studies suggested that epicardial fat may have an important role in the pathogenesis of CAD. Therefore, the association between epicardial fat volume (EFV) and left ventricular function with CAD was investigated in the present study. A total of 61 patients with suspected CAD who underwent CT scanning were enrolled. Baseline data, parameters of left heart function and EFV of the subjects were collected and analyzed. The degree of coronary artery lesions was assessed using the Gensini score. Pearson's correlation analysis and a logistic regression model were applied to assess the association between EFV and risk factors for CAD, the Gensini score and left ventricular function index. A total of 29 female and 32 male subjects with a median age of 63 years were enrolled. The median body mass index (BMI) of the subjects was 23.37 kg/m2 and the median EFV was 86.41 cm3. It was revealed that risk factors of CAD, specially hypertension, diabetes mellitus, dyslipidemia, history of myocardial infarction and smoking, had no significant association with the EFV (P>0.05); however, the EFV was significantly positively correlated with the BMI (r=0.479, P<0.0001), interventricular septal thickness (r=0.436, P=0.004), left ventricular posterior wall thickness (r=0.350, P=0.0058), left ventricular end diastolic diameter (r=0.265, P=0.0388), left ventricular mass (r=0.445, P=0.0003) and left ventricular mass index (r=0.371, P=0.0035). However, no correlation was identified between the EFV and the Gensini score (r=0.131, P=0.3137). In conclusion, the EFV measured by cardiac CT scanning was positively correlated with the BMI and left ventricular function, but was not associated with the presence of CAD according to the Gensini scores.

Abstract
AbstractDespite advances in secondary prevention strategies in patients with cardiovascular disease, the residual risk of recurrent atherothrombotic events remains high. Dual-antiplatelet therapy is the standard of care for secondary prevention in patients with acute coronary syndrome (ACS), whereas single antiplatelet therapy, generally with aspirin, is the standard of care for secondary prevention in stable patients with coronary artery disease (CAD), peripheral artery disease (PAD), or cerebrovascular disease. However, atherosclerotic plaque disruption not only triggers platelet activation but also results in thrombin generation because of tissue factor exposure. Therefore, blocking both pathways by combining antiplatelet therapy with an anticoagulant, or dual pathway inhibition (DPI), has the potential to be more effective than inhibiting either pathway alone. The benefit of DPI has been demonstrated in the ATLAS ACS 2-TIMI 51, COMPASS, and VOYAGER PAD trials, where the combination of rivaroxaban vascular dose (2.5 mg twice daily) plus aspirin significantly reduced the risk of atherothrombotic events compared with aspirin across a broad range of patients, including those with recent ACS, those with chronic CAD and/or PAD, and patients with PAD who have undergone peripheral revascularization. This article provides the rationale for this regimen in more detail, including why the DPI regimen with the rivaroxaban vascular dose was developed for vascular protection in a broad spectrum of patients with atherosclerotic disease.

Abstract
BACKGROUND Elevated mean platelet volume (MPV) and immature platelet fraction (IPF) are predictive for vascular risk. Both can be associated with residual platelet reactivity. We aimed to explore associations among platelet characteristics and responder status in stroke patients on clopidogrel. METHODS Blood samples from 46 patients and 15 healthy subjects were analyzed for platelet count, MPV, IPF, large cell ratio (LCR) and high-fluorsecent immature platelet fraction (H-IPF). As a novelty, not only whole blood, but upper and lower half blood samples after 1-hour gravity sedimentation were analyzed. Platelet aggregometry was used for the whole blood and separated samples to explore area under the curve (AUC) in patients and controls. RESULTS The AUC of the whole blood showed significant differences compared to the upper and lower samples separated after 1-hour sedimentation in patients and controls (p < 0.001 and p = 0.005 respectively). Remarkably, AUC measured in the upper samples in 59% of patients on clopidogrel were exceeding the therapeutic range suggesting that ascending platelets exert aggregation in the presence of ADP. This observation was associated with increased MPV and LCR in the upper samples (both p = 0.04). Patients on clopidogrel were characterized as responders and non-responders and the percentage of H-IPF was significantly higher among non-responders compared to controls in the upper samples (p = 0.04). CONCLUSIONS The modified platelet function test may help to stratify patients with high residual platelet reactivity.

Abstract
Arterial thrombosis is a result of complex interaction between blood cells, soluble coagulation factors in plasma and vessel wall. Antiplatelet drugs do not always provide the necessary antithrombotic effect of sufficient strength, because their influence does not extend to all three factors involved in this process. Low doses of direct oral inhibitors of thrombin are able to potentiate antithrombotic effect of antiplatelet therapy. The combination of rivaroxaban in a dose of 2.5 mg and standard double antiplatelet therapy turned out to be the most promising for clinical use, since studies with dabigatran and apixaban at the II and III stages of the trials were found to be unsuccessful due to the unacceptably high frequency of bleeding. Studies of the combination of rivaroxaban at a dose of 2.5 mg and standard antiplatelet therapy conducted in previous years among patients with acute myocardial infarction showed a decrease in the frequency of complications of atherothrombosis associated with their ischemic nature, while at the same time there was a slight increase in hemorrhagic complications. In the COMPASS study the combination of rivaroxaban (2.5 mg) plus aspirin reduced the risk of the primary endpoint (myocardial infarction, ischemic stroke, cardiovascular death) more significantly than aspirin alone in patients with stable ischemic heart disease and ischemic brain disease. The pathophysiological rationales for the use of low doses of rivaroxaban when added to dual antiplatelet therapy are considered, and the significance of recent studies in patients with acute coronary syndrome, stable ischemic heart disease and in the prevention of ischemic stroke is discussed.

Abstract
The article discusses modern approaches to the conceptualization of pathogenetic heterogeneity in various branches of medical science. The concepts of endophenotype, endotype, and residual cardiovascular risk and the scope of their application in internal medicine and cardiology are considered. Based on the latest results of studies of the genetic architecture of atherosclerosis, five endotypes of atherosclerosis have been proposed. Each of the presented endotypes represents one or another pathophysiological mechanism of atherogenesis, having an established genetic substrate, a characteristic panel of biomarkers, and a number of clinical features. Clinical implications and perspectives for the study of endotypes of atherosclerosis are briefly reviewed.

Abstract
Objectives Coagulation mechanisms and fibrinolytic assembly are important components role players of acute myocardial infarction (AMI) progression. Our study objective was to see the serial variations in the levels of Von Willebrand factor (VWF) and A Disintegrin and Metalloprotease with ThromboSpondin motif (ADAMTS13) over the course of AMI and to determine their relationship with the cardiovascular risk markers and the patient's clinical characteristics. Methods This project was done at the departments of Emergency Medicine, Physiology and Cardiac sciences of King Saud University Medical City. We studied ADAMTS13, VWF, fibrinogen, and CRP levels in 80 patients with AMI when patients were admitted; post AMI by 3-4 days and at follow-up of 3 months. We compared them with a control group consisting of 36 subjects. Results AMI had significantly lower levels of ADAMTS13 at AMI and after 3-4 days; at follow-up the difference in levels was nonsignificant, when compared with controls. Similarly, VWF levels were significantly higher in AMI and remained high even at follow-up compared to control subjects. VWF/ADAMTS13 ratio was also significantly higher at AMI and 3-4 days while at follow-up difference was nonsignificant compared to control subjects. Regression analysis between hsCRP and ADAMTS13 showed an inverse relationship (r = 0.376, p < 0.01), while correlation with VWF was significantly positive (r = 0.376, p < 0.01), while correlation with VWF was significantly positive (. Conclusions Increased levels of VWF and reduced levels of ADAMTS13 activity may contribute to the pathogenesis of acute myocardial infarction and might prove to be important mediators of AMI progression.

Abstract
BACKGROUND Endothelial cells regulate the formation of blood clots; thus, genes selectively expressed in these cells could primarily determine thrombus formation. Apold1 (apolipoprotein L domain containing 1) is a gene expressed by endothelial cells; whether Apold1 directly contributes to arterial thrombosis has not yet been investigated. Here, we assessed the effect of Apold1 deletion on arterial thrombus formation using an in vivo model of carotid thrombosis induced by photochemical injury. MATERIAL AND METHODS Apold1 knockout (Apold1-/- ) mice and wild-type (WT) littermates underwent carotid thrombosis induced by photochemical injury, and time to occlusion was recorded. Tissue factor (TF) activity and activation of mitogen-activated protein kinases (MAPKs) and phosphatidyl-inositol-3 kinase (PI3K)/Akt pathways were analysed by colorimetric assay and Western blotting in both Apold1-/- and WT mice. Finally, platelet reactivity was assessed using light transmission aggregometry. RESULTS After photochemical injury, Apold1-/- mice exhibited shorter time to occlusion as compared to WT mice. Moreover, TF activity was increased in carotid arteries of Apold1-/- when compared to WT mice. Underlying mechanistic markers such as TF mRNA and MAPKs activation were unaffected in Apold1-/- mice. In contrast, phosphorylation of Akt was reduced in Apold1-/- as compared to WT mice. Additionally, Apold1-/- mice displayed increased platelet reactivity to stimulation with collagen compared with WT animals. CONCLUSIONS Deficiency of Apold1 results in a prothrombotic phenotype, accompanied by increased vascular TF activity, decreased PI3K/Akt activation and increased platelet reactivity. These findings suggest Apold1 as an interesting new therapeutic target in the context of arterial thrombosis.

Abstract
Platelets - blood cells continuously produced from megakaryocytes mainly in the bone marrow - are implicated not only in haemostasis and arterial thrombosis, but also in other physiological and pathophysiological processes. This Review describes current evidence for the heterogeneity in platelet structure, age, and activation properties, with consequences for a diversity of platelet functions. Signalling processes of platelet populations involved in thrombus formation with ongoing coagulation are well understood. Genetic approaches have provided information on multiple genes related to normal haemostasis, such as those encoding receptors and signalling or secretory proteins, that determine platelet count and/or responsiveness. As highly responsive and secretory cells, platelets can alter the environment through the release of growth factors, chemokines, coagulant factors, RNA species, and extracellular vesicles. Conversely, platelets will also adapt to their environment. In disease states, platelets can be positively primed to reach a pre-activated condition. At the inflamed vessel wall, platelets interact with leukocytes and the coagulation system, interactions mediating thromboinflammation. With current antiplatelet therapies invariably causing bleeding as an undesired adverse effect, novel therapies can be more beneficial if directed against specific platelet responses, populations, interactions, or priming conditions. On the basis of these novel concepts and processes, we discuss several initiatives to target platelets therapeutically.

Abstract
Atherosclerosis is a multifactorial vascular disease that develops in the course of a lifetime. Numerous risk factors for atherosclerosis have been identified, mostly inflicting pro-inflammatory effects. Vessel injury, such as occurring during erosion or rupture of atherosclerotic lesions triggers blood coagulation, in attempt to maintain hemostasis (protect against bleeding). However, thrombo-inflammatory mechanisms may drive blood coagulation such that thrombosis develops, the key process underlying myocardial infarction and ischemic stroke (not due to embolization from the heart). In the blood coagulation system, platelets and coagulation proteins are both essential elements. Hyperreactivity of blood coagulation aggravates atherosclerosis in preclinical models. Pharmacologic inhibition of blood coagulation, either with platelet inhibitors, or better documented with anticoagulants, or both, limits the risk of thrombosis and may potentially reverse atherosclerosis burden, although the latter evidence is still based on animal experimentation.Patients at risk of atherothrombotic complications should receive a single antiplatelet agent (acetylsalicylic acid, ASA, or clopidogrel); those who survived an atherothrombotic event will be prescribed temporary dual antiplatelet therapy (ASA plus a P2Y12 inhibitor) in case of myocardial infarction (6-12 months), or stroke (<6 weeks), followed by a single antiplatelet agent indefinitely. High risk for thrombosis patients (such as those with peripheral artery disease) benefit from a combination of an anticoagulant and ASA. The price of gained efficacy is always increased risk of (major) bleeding; while tailoring therapy to individual needs may limit the risks to some extent, new generations of agents that target less critical elements of hemostasis and coagulation mechanisms are needed to maintain efficacy while reducing bleeding risks.

Abstract
Adenosine is an endogenous nucleoside with a short half-life that regulates many physiological functions involving the heart and cardiovascular system. Among the cardioprotective properties of adenosine are its ability to improve cholesterol homeostasis, impact platelet aggregation and inhibit the inflammatory response. Through modulation of forward and reverse cholesterol transport pathways, adenosine can improve cholesterol balance and thereby protect macrophages from lipid overload and foam cell transformation. The function of adenosine is controlled through four G-protein coupled receptors: A1, A2A, A2B and A3. Of these four, it is the A2A receptor that is in a large part responsible for the anti-inflammatory effects of adenosine as well as defense against excess cholesterol accumulation. A2A receptor agonists are the focus of efforts by the pharmaceutical industry to develop new cardiovascular therapies, and pharmacological actions of the atheroprotective and anti-inflammatory drug methotrexate are mediated via release of adenosine and activation of the A2A receptor. Also relevant are anti-platelet agents that decrease platelet activation and adhesion and reduce thrombotic occlusion of atherosclerotic arteries by antagonizing adenosine diphosphate-mediated effects on the P2Y12 receptor. The purpose of this review is to discuss the effects of adenosine on cell types found in the arterial wall that are involved in atherosclerosis, to describe use of adenosine and its receptor ligands to limit excess cholesterol accumulation and to explore clinically applied anti-platelet effects. Its impact on electrophysiology and use as a clinical treatment for myocardial preservation during infarct will also be covered. Results of cell culture studies, animal experiments and human clinical trials are presented. Finally, we highlight future directions of research in the application of adenosine as an approach to improving outcomes in persons with cardiovascular disease.
