Defining Strategies of Modulation of Antiplatelet Therapy in Patients With Coronary Artery Disease: A Consensus Document from the Academic Research Consortium.

Antiplatelet therapy is the mainstay of pharmacologic treatment to prevent thrombotic or ischemic events in patients with coronary artery disease treated with percutaneous coronary intervention and those treated medically for an acute coronary syndrome. The use of antiplatelet therapy comes at the expense of an increased risk of bleeding complications. Defining the optimal intensity of platelet inhibition according to the clinical presentation of atherosclerotic cardiovascular disease and individual patient factors is a clinical challenge. Modulation of antiplatelet therapy is a medical action that is frequently performed to balance the risk of thrombotic or ischemic events and the risk of bleeding. This aim may be achieved by reducing (ie, de-escalation) or increasing (ie, escalation) the intensity of platelet inhibition by changing the type, dose, or number of antiplatelet drugs. Because de-escalation or escalation can be achieved in different ways, with a number of emerging approaches, confusion arises with terminologies that are often used interchangeably. To address this issue, this Academic Research Consortium collaboration provides an overview and definitions of different strategies of antiplatelet therapy modulation for patients with coronary artery disease, including but not limited to those undergoing percutaneous coronary intervention, and consensus statements on standardized definitions.

A Personalized Approach for Patients with Myocardial Infarction with Non-Obstructive Coronary Arteries.

Myocardial infarction with non-obstructive coronary arteries (MINOCA) includes coronary embolism, dissection, spasm and microvascular dysfunction, as well as plaque rupture or erosion (causing < 50% stenosis). In the most recent studies, events that can be classified as MINOCA account for approximately 6-8% of all diagnoses of acute myocardial infarction (AMI). Clinical suspect may suggest the need for additional diagnostic procedures beyond the usual coronary angiography, such as cardiac imaging or provocative tests. Cardiac magnetic resonance (CMR) is essential for both validating the diagnosis and ruling out other conditions with a comparable clinical presentation. The prognosis is not as good as previously believed; rather, it is marked by morbidity and mortality rates comparable to those of other types of AMI. Identification of the underlying causes of MINOCA is recommended by current guidelines and consensus documents in order to optimize treatment, enhance prognosis, and encourage prevention of recurrent myocardial infarction. In this narrative review, we have outlined the various causes of MINOCA and their specific therapies in an attempt to identify a personalized approach to its treatment.

ANMCO/SIMEU consensus document on the use of reversal agents for antithrombotic therapies in patients with ongoing bleeding or at high risk of haemorrhagic events.

In recent decades, an incredible evolution in antithrombotic therapies used for treating patients with atherosclerosis, atrial fibrillation, and venous thromboembolism has been observed, leading to the availability of increasingly safe drugs. Nonetheless, bleeding complications remain a significant concern, with considerable health, social, and economic implications. To improve the acute management of patients experiencing or at risk for major bleeding events, specific reversal agents for antithrombotic drugs have been recently developed. While these agents demonstrate effectiveness in small-scale pharmacodynamic studies and clinical trials, it is imperative to balance the benefits of reversing antiplatelet or anticoagulant therapy against the risk of prothrombotic effects. These risks include the potential loss of antithrombotic protection and the prothrombotic tendencies associated with bleeding, major surgery, or trauma. This joint document of the Italian Association of Hospital Cardiologists (Associazione Nazionale Medici Cardiologi Ospedalieri) and the Italian Society of Emergency Medicine (Società Italiana di Medicina d'Emergenza-Urgenza) delineates the key features and efficacy of available reversal agents. It also provides practical flowcharts to guide their use in patients with active bleeding or those at elevated risk of major bleeding events.

Italian Association of Hospital Cardiologists position paper-obesity in adults: a clinical primer.

Obesity is a chronic and relapsing disease characterized by the interaction between individual predispositions and an obesogenic environment. Recent advances in understanding the mechanisms of energetic homoeostasis paved the way to more effective therapeutic approaches compared with traditional treatments. Since obesity is a complex disease, it necessitates a multi-disciplinary approach whose implementation remains challenging. Nonetheless, emerging pharmacological interventions appear promising. Currently, therapeutic success is discreet in the short term but often fails to maintain long-term weight loss due to a high likelihood of weight regain. Cardiologists play a key role in managing patients with obesity, yet often lack familiarity with its comprehensive management. The aim of this document is to summarize knowledge to consolidate essential knowledge for clinicians to effectively treat patients living with obesity. The paper emphasizes the pivotal role of a strong patient-clinician relationship in navigating successful treatment. We analyse the criteria commonly used to diagnose obesity and point out the strengths and limitations of different criteria. Furthermore, we discuss the role of obesiologists and the contributions of cardiologists. In addition, we detail key components of effective therapeutic strategies, including educational aspects and pharmacological options.

Associazione Nazionale Medici Cardiologi Ospedalieri (ANMCO) scientific statement on the simplification of the drug regimen for secondary cardiovascular prevention.

The issue of suboptimal drug regimen adherence in secondary cardiovascular prevention presents a significant barrier to improving patient outcomes. To address this, the utilization of drug combinations, specifically single pill combinations (SPCs) and polypills, was proposed as a strategy to simplify treatment regimens. This approach aims to enhance treatment accessibility, affordability, and adherence, thereby reducing healthcare costs and improving patient health. The document is an Associazione Nazionale Medici Cardiologi Ospedalieri (ANMCO) scientific statement on simplifying drug regimens for secondary cardiovascular prevention. It discusses the underuse of treatments despite available, effective, and accessible options, highlighting a significant gap in secondary prevention across different socio-economic statuses and countries. The statement explores barriers to implementing evidence-based treatments, including patient, healthcare provider, and system-related challenges. The paper also reviews international guidelines, the role of SPCs and polypills in clinical practice, and their economic impact, advocating for their use in secondary prevention to improve patient outcomes and adherence.

Cardio-oncology rehabilitation: are we ready?

Cardio-oncology rehabilitation (CORE) is not only an essential component of cancer rehabilitation but also a pillar of preventive cardio-oncology. Cardio-oncology rehabilitation is a comprehensive model based on a multitargeted approach and its efficacy has been widely documented; when compared with an 'exercise only' programme, comprehensive CORE demonstrates a better outcome. It involves nutritional counselling, psychological support, and cardiovascular (CV) risk assessment, and it is directed to a very demanding population with a heavy burden of CV diseases driven by physical inactivity, cancer therapy-induced metabolic derangements, and cancer therapy-related CV toxicities. Despite its usefulness, CORE is still underused in cancer patients and we are still at the dawning of remote models of rehabilitation (tele-rehabilitation). Not all CORE is created equally: a careful screening procedure to identify patients who will benefit the most from CORE and a multidisciplinary customized approach are mandatory to achieve a better outcome for cancer survivors throughout their cancer journey. The aim of this paper is to provide an updated review of CORE not only for cardiologists dealing with this peculiar population of patients but also for oncologists, primary care providers, patients, and caregivers. This multidisciplinary team should help cancer patients to maintain a healthy and active life before, during, and after cancer treatment, in order to improve quality of life and to fight health inequities.

Impact of diabetes on long-term outcomes of bifurcation percutaneous coronary intervention. An analysis from the BIFURCAT registry.

BACKGROUND: It is still unclear the impact of diabetes mellitus (DM) in complex coronary lesions treated with percutaneous coronary intervention (PCI) which themselves are at increased incidence of adverse events. METHODS: BIFURCAT registry encompassed patients treated with PCI for coronary bifurcation lesion from the COBIS III and the RAIN registry. The primary endpoint was the occurrence of major cardiovascular adverse event (MACE), a composite and mutual exclusive of all-cause death or myocardial infarction (MI) or target-lesion revascularization (TLR). A total of 5537 patients were included in the analysis and 1834 (33%) suffered from DM. RESULTS: After a median follow-up of 21 months, diabetic patients had a higher incidence of MACE (17% vs. 9%, p < 0.001), all-cause mortality (9% vs. 4%, p < 0.001), TLR (5% vs. 3%, p = 0.001), MI (4% vs. 2%, p < 0.001), and stent thrombosis (ST) (2% vs. 1%, p = 0.007). After multivariate analysis, diabetes remained significantly associated with MACE (hazard ratio [HR]: 1.37; confidence interval [CI]: 1.13-1.65; p = 0.001), all-cause death (HR: 1.65; 95% CI: 1.24-2.19, p = 0.001), TLR (HR: 1.45; CI: 1.03-2.04; p = 0.031) and ST (HR: 1.73, CI: 1.04-2.88; p = 0.036), but not with MI (HR: 1.34; CI: 0.93-1.92; p = 0.11). Among diabetics, chronic kidney disease (HR: 2.99; CI: 2.21-4.04), baseline left ventricular ejection fraction (HR: 0.98; CI: 0.97-0.99), femoral access (HR: 1.62; CI: 1.23-2.15), left main coronary artery (HR: 1.44; CI: 1.06-1.94), main branch diameter (HR: 0.79; CI: 0.66-0.94) and final kissing balloon (HR: 0.70; CI: 0.52-0.93) were independent predictors of MACE at follow-up. CONCLUSIONS: Patients with DM treated with PCI for coronary bifurcations have a worse prognosis due to higher incidence of MACE, all-cause mortality, TLR and ST compared to the non-diabetics.

Prevalence and predictive role of hypertriglyceridemia in statin-treated patients at very high risk: Insights from the START study.

BACKGROUND AND AIM: Elevated triglyceride (TG) levels seem to identify subjects at increased cardiovascular risk, independent of LDL-C levels. We sought to evaluate the predictive role of hypertriglyceridemia, defined as TG levels ≥150 mg/dl, in very high risk (VHR) patients with chronic coronary syndromes (CCS) treated with statins. METHODS AND RESULTS: Using the data from the STable Coronary Artery Diseases RegisTry (START) study, an Italian nationwide registry, we assessed the association between the TG levels and baseline clinical characteristics, pharmacological treatment and major adverse cardio-cerebrovascular events (MACCE) at 1 year in a large cohort of statin-treated patients at VHR. Of the 4751 consecutive patients with CCS enrolled in the registry and classified as VHR, 2652 (55.8%) had TG values available (mean 120.6 ± 54.9) and were treated with at least a statin at baseline: 2019 (76.1%) with TG < 150 and 633 (23.9%) with TG ≥ 150 mg/dl. At 1 year from enrolment, MACCE occurred in 168 (6.3%) patients, without differences between the two groups of TG (5.9 vs 7.6%; p = 0.14). At multivariable analysis, hypertriglyceridemia did not result as independent predictor of the MACCE (hazard ratio: 1.16; 95% confidence intervals: 0.82-1.64; p = 0.42). CONCLUSIONS: In the present large, nationwide cohort of consecutive CCS patients at VHR with statin-controlled LDL-C levels, hypertriglyceridemia was present in around 24% of cases and did not result as predictor of MACCE at 1 year. Further studies with a longer follow-up and larger sample size are needed to better define the prognostic role of TG levels when intensive LDL lowering therapies are used.

Low-dose rivaroxaban: can cardiovascular events be reduced?

Despite available effective guideline-based preventive therapies, patients with vascular diseases remain at high-risk of recurrent ischaemic events. Novel therapeutic strategies are therefore needed in order to further reduce the residual risk that is present in these high-risk patients. The Cardiovascular Outcomes for People using Anticoagulation Strategies trial demonstrated that, in patients with chronic coronary artery disease (CAD) and peripheral artery disease (PAD), a combination of rivaroxaban 2.5 mg/bid (vascular dose) and acetylsalicylic acid (ASA) 100 mg once daily, the so-called dual pathway inhibition (DPI), reduced cardiovascular death, stroke, or myocardial infarction by 24% and mortality by 18%, as compared with ASA-alone. The rationale that can explain the improvement of cardiovascular outcome is that platelet aggregation and fibrin formation are involved in arterial thrombosis and rivaroxaban is able to target both ways and has a synergic effect with ASA. The aim of this review is to discuss the potential mechanisms and added benefits of DPI, in patients with PAD and CAD.

The PACMAN-AMI trial: a revolution in the treatment of acute coronary syndromes.

After an acute coronary syndrome (ACS), the risk of major adverse cardiovascular events (MACE) persists despite the reperfusion of the culprit lesion. The addition of proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) to standard lipid-lowering therapies has been demonstrated to effectively reduce the levels of low-density lipoprotein cholesterol (LDL-C), with a consistent decrease of MACE in large, randomized clinical trials enrolling patients at high risk of cardiovascular events. There is a strong rationale for an immediate and aggressive LDL-C lowering with the use of PCSK9i in ACS patients. The PACMAN-AMI trial tested this hypothesis demonstrating that in ACS patients, the addition of subcutaneous biweekly alirocumab, compared with placebo, to high-intensity statin therapy resulted in significantly greater coronary plaque regression in non-infarct-related arteries after 52 weeks, as assessed by novel intra-coronary imaging modalities. These findings might provide the mechanistic rationale in favour of early initiation of very intensive LDL-C-lowering therapy in the acute setting of ACS, potentially modifying the actual common pattern of treatment.

ANMCO-SIMEU consensus document: appropriate management of atrial fibrillation in the emergency department.

Atrial fibrillation (AF) accounts for 2% of the total presentations to the emergency department (ED) and represents the most frequent arrhythmic cause for hospitalization. It steadily increases the risk of thromboembolic events and is often associated with several comorbidities that negatively affect patient's quality of life and prognosis. AF has a considerable impact on healthcare resources, making the promotion of an adequate and coordinated management of this arrhythmia necessary in order to avoid clinical complications and to implement the adoption of appropriate technological and pharmacological treatment options. AF management varies across regions and hospitals and there is also heterogeneity in the use of anticoagulation and electric cardioversion, with limited use of direct oral anticoagulants. The ED represents the first access point for early management of patients with AF. The appropriate management of this arrhythmia in the acute setting has a great impact on improving patient's quality of life and outcomes as well as on rationalization of the financial resources related to the clinical course of AF. Therefore, physicians should provide a well-structured clinical and diagnostic pathway for patients with AF who are admitted to the ED. This should be based on a tight and propositional collaboration among several specialists, i.e. the ED physician, cardiologist, internal medicine physician, anesthesiologist. The aim of this ANMCO-SIMEU consensus document is to provide shared recommendations for promoting an integrated, accurate, and up-to-date management of patients with AF admitted to the ED or Cardiology Department, in order to make it homogeneous across the national territory.

ANMCO position paper on vericiguat use in heart failure: from evidence to place in therapy.

In the growing therapeutic armamentarium for heart failure (HF) management, vericiguat represents an innovative therapeutic option. The biological target of this drug is different from that of other drugs for HF. Indeed, vericiguat does not inhibit neuro-hormonal systems overactivated in HF or sodium-glucose co-transporter 2 but stimulates the biological pathway of nitric oxide and cyclic guanosine monophosphate, which is impaired in patients with HF. Vericiguat has recently been approved by international and national regulatory authorities for the treatment of patients with HF and reduced ejection fraction who are symptomatic despite optimal medical therapy and have worsening HF. This ANMCO position paper summarises key aspects of vericiguat mechanism of action and provides a review of available clinical evidence. Furthermore, this document reports use indications based on international guideline recommendations and local regulatory authority approval at the time of writing.

ANMCO position paper on the management of hypercholesterolaemia in patients with acute coronary syndrome.

Patients suffering from acute coronary syndrome (ACS) present a high risk of recurrence and new adverse cardiovascular events after hospital discharge. Elevated plasma LDL-cholesterol (LDL-C) levels have been shown to be a causal factor for the development of coronary heart disease, and robust clinical evidence has documented that LDL-C levels decrease linearly correlates with a reduction in cardiovascular events. Recent studies have also demonstrated the safety and efficacy of an early and significant reduction in LDL-C levels in patients with ACS. In this position paper, Italian Association of Hospital Cardiologists proposes a decision algorithm on early adoption of lipid-lowering strategies at hospital discharge and short-term follow-up of patients with ACS, in the light of the multiple evidence generated in recent years on the treatment of hypercholesterolaemia and the available therapeutic options, considering current reimbursement criteria.

Management of acute coronary syndromes in older adults.

Older patients are underrepresented in prospective studies and randomized clinical trials of acute coronary syndromes (ACS). Over the last decade, a few specific trials have been conducted in this population, allowing more evidence-based management. Older adults are a heterogeneous, complex, and high-risk group whose management requires a multidimensional clinical approach beyond coronary anatomic variables. This review focuses on available data informing evidence-based interventional and pharmacological approaches for older adults with ACS, including guideline-directed management. Overall, an invasive approach appears to demonstrate a better benefit-risk ratio compared to a conservative one across the ACS spectrum, even considering patients' clinical complexity and multiple comorbidities. Conversely, more powerful strategies of antithrombotic therapy for secondary prevention have been associated with increased bleeding events and no benefit in terms of mortality reduction. An interdisciplinary evaluation with geriatric assessment should always be considered to achieve a holistic approach and optimize any treatment on the basis of the underlying biological vulnerability.

Acute coronary syndrome and renal impairment: a systematic review.

BACKGROUND: Coronary artery disease (CAD) and chronic kidney disease (CKD) may reciprocally influence each other. Patients with CAD and CKD have an increased risk of both ischemic and hemorrhagic events. METHODS: In the present review, we summarize the existing literature focusing on the relationship between kidney dysfunction and acute coronary syndromes (ACS) in terms of risk factors, complications, and prognosis. We discuss also about the best evidence-based strategies to prevent deterioration of renal function in patients with CAD. RESULTS: Patients with CKD less frequently receive an invasive management (percutaneous or surgical revascularization) and potent antithrombotic drugs. Nevertheless, recent evidence suggests they would benefit from a selective invasive management, especially in case of ACS. CONCLUSION: Patients with CKD and CAD represent a challenging population, more randomized controlled trials and meta-analyses are needed to better define the best therapeutic strategy during an ACS episode.

Prevalence and clinical impact of high platelet reactivity in patients with chronic kidney disease treated with percutaneous coronary intervention: An updated systematic review and meta-analysis.

BACKGROUND: High platelet reactivity (HPR) on clopidogrel and chronic kidney disease (CKD) are recognized as potent risk factors for adverse outcomes in patients suffering coronary artery disease (CAD) and undergoing percutaneous coronary intervention (PCI). However, conclusive evidence regarding their reciprocal interaction and the consequent impact on clinical events is still lacking. OBJECTIVES: We performed a metaanalysis with the aim to evaluate the prevalence of HPR in patients with and without CKD and the incidence of major adverse cardiovascular events (MACE) according to the renal and platelet function status in current literature (co-primary endpoints). Secondary endpoints were myocardial infarction (MI), all-cause death, and definite/probable stent thrombosis (ST). METHODS: We searched on PubMed, EMBASE, and Cochrane Library studies investigating CKD and HPR on clopidogrel in patients suffering CAD who underwent PCI and their related outcomes. Overall, 13 studies including 22.464 patients were selected. Odds ratios (ORs) and 95% confidence intervals (CI) were calculated using a random-effects model with the Mantel-Haenszel method. RESULTS: Patients with CKD presented significantly higher odds of HPR compared with those without CKD (OR 1.51 [95% CI: 1.29, 1.76]). In patients without CKD, HPR was associated with increased odds of MACE (OR 1.31 [95% CI: 1.01, 1.72]), MI (OR 1.48 [95% CI: 1.17, 1.86]) and definite/probable ST (OR 2.45 [95% CI: 1.08, 5.60]). In patients with CKD, HPR was associated with higher odds of both MACE (OR 1.61 [95% CI: 1.14, 2.27]) and MI (OR 1.69 [95% CI: 1.11, 2.59]), compared to those without HPR. CONCLUSIONS: Our analysis shows that HPR on clopidogrel is more frequent in patients with CKD treated with PCI. Patients with HPR are exposed to a high risk of MACE after PCI, regardless of the renal function status.

Determinants and long-term outcomes of largely uncovered struts in thin-struts drug-eluting stents assessed by optical coherence tomography.

BACKGROUND: Uncovered struts are a determinant of stent failure. The impact of plaque composition and procedural factors on the occurrence, evolution, and outcomes of uncovered struts in a high-risk setting has not been investigated. OBJECTIVE: To investigate the determinants and long-term clinical impact of largely uncovered struts (LUS) in thin-struts drug-eluting stents (DES) implanted in complex lesions by intracoronary optical coherence tomography (OCT). METHODS: Ninety patients with multivessel disease undergoing staged complete revascularization were randomly assigned to bioabsorbable or durable polymer DES. OCT were serially performed during the index procedure, at 3- and 18-month follow-up, and analyzed by an independent core lab. Struts were defined uncovered by OCT if no tissue was visible above the struts. LUS were defined as ≥30% of uncovered struts at 3-month follow-up. Clinical outcomes were the occurrence of target vessel failure (TVF) and major adverse cardiac and cerebrovascular events (MACCE) at 5-year follow-up. RESULTS: LUS occurred in 31 patients (34.4%) regardless of stent platform. At 5 years, no differences were observed in the rate of TVF (12.7% vs. 13.4%; p = 0.91) and MACCE (23.9% vs. 24.9%; p = 0.88) between the two groups. At multivariate logistic regression, plaque rupture, mean lumen diameter, proximal reference vessel area, and maximum stent deployment pressure were independent predictors of LUS. CONCLUSIONS: LUS are a frequent finding in complex coronary lesions treated with thin-struts DES, especially in the presence of plaque rupture. However, in this study, no significant safety signal related to LUS emerged in long-term follow-up.

Incidence, Characteristics, and Management of Patients with Recurrent Myocardial Infarctions: Insights from the EYESHOT POST-MI.

Background: It is unknown whether patients who survived two or multiple episodes of myocardial infarction (MI) present different clinical characteristics and management than patients at their first MI. Methods: The EYESHOT post-MI was a prospective, observational, nationwide study aimed to evaluate the management of patients presenting to cardiologists 1 to 3 years from the last MI event. In 3 months of enrolment, 165 Italian cardiology centers included 1633 consecutive post-MI patients. In the present analysis, we stratified the study cohort according to the number of prior MI episodes (i.e., 1, 2 or ≥3). Results: Among the 1618 patients enrolled with complete data on MI history, 1335 (82.5%) were at their first MI episode, 209 (12.9%) had a history of 2 MIs, and the remaining 74 (4.6%) had ≥ 3 prior MIs. Patients with a history of multiple MIs were increasingly older and presented a significantly higher rate of risk factors compared to those at their first MI. During the year prior to enrolment, patients with 2 or ≥3 MI episodes more frequently underwent coronary angiography compared to the other group (p < 0.0001). In addition, several lifesaving and antianginal drugs were more frequently prescribed in patients presenting with a history of multiple MIs compared to those at their first MI. Conclusions: Our data suggest that patients with multiple MIs managed by cardiologists in routine clinical practice present an incremental clinical risk, more frequently undergo coronary angiography, and are more intensively managed with pharmacological therapies compared to patients at their first MI episode.

Could the PARIS Risk Scores Be Useful for the Choice of Triple versus Dual Antithrombotic Therapy in Patients with Atrial Fibrillation Undergoing Percutaneous Coronary Intervention?

INTRODUCTION: Current guidelines recommend dual antithrombotic therapy (DAT) for the majority of patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) and suggest a short course of triple antithrombotic therapy (TAT) for those at very high thrombotic risk (TR) but low bleeding risk (BR). METHODS: We analyze if the PARIS ischemic-hemorrhagic scale could be useful for the choice of antithrombotic strategy in patients with acute coronary syndromes and AF treated with coronary stenting enrolled in the prospective, observational, nationwide MATADOR-PCI study. RESULTS: Among the 588 patients discharged alive, a TAT was prescribed in 381 (64.8%) and DAT in 52 (8.8%) patients. According to the PARIS scoring system, 142 (24.2%) were classified as low, 244 (41.5%) as intermediate, and 292 (34.3%) as high TR. In parallel, 87 (14.8%) were categorized in the low, 260 (44.2%) in the intermediate, and 241 (41.0%) in the high-risk stratum for major bleedings. Crossing the various strata of the two PARIS risk scores, the largest group of patients consisted of those at high TR and BR (n = 130, 22%), followed by those at intermediate risk according to both scores (n = 122, 21%). At discharge, TAT was mainly used in patients at intermediate to high BR, while DAT in those at intermediate to high TR but low BR, according to the PARIS score. CONCLUSION: Our data suggest that some variables associated with increased TR or BR are poorly considered in the daily practice, while the use of PARIS scales could help in the implementation of guidelines' recommendations.

Impact of serum uric acid levels on cardiovascular events and quality of life in patients with chronic coronary syndromes: Insights from a contemporary, prospective, nationwide registry.

BACKGROUND AND AIMS: Hyperuricemia is a metabolic disorder that has been associated with adverse cardiovascular (CV) events. Using the data from a nationwide, prospective registry on patients with chronic coronary syndromes (CCS), we assessed the impact of serum uric acid (SUA) levels on quality of life (QoL) and major adverse CV events (MACE), a composite of CV death and hospitalization for myocardial infarction, heart failure (HF), angina or revascularization at 1-year. METHODS AND RESULTS: Among the 5070 consecutive CCS patients enrolled in the registry, levels of SUA were available for 2394 (47.2%). Patients with SUA levels available at baseline were grouped as low tertile (n = 860; 4.3 [3.7-4.7] mg/dL), middle tertile (n = 739; 5.6 [5.3-5.9] mg/dL) and high tertile (n = 795; 7.1 [6.7-7.9] mg/dL). At 1 year, the incidence of MACE was 3.7%, 4.1% and 6.8% for low, middle and high tertiles, respectively (p = 0.005 for low vs high tertile). Patients in the high tertile of SUA had a significantly higher rate of CV mortality (1.4% vs 0.4%; p = 0.05) and hospital admission for HF (2.8% vs 1.6%; p = 0.03) compared to the low tertile. However, hyperuricemia did not result as an independent predictor of MACE at multivariable analysis [hazard ratio: 1.27; 95% confidence intervals: 0.81-2.00; p = 0.3]. CONCLUSIONS: In this contemporary, large cohort of CCS, those in the high tertile of SUA had a greater burden of CV disease and worse QoL. However, SUA did not significantly influence the higher rate of CV mortality, hospitalization for HF and MACE observed in these patients during 1-year follow-up.
