RESUMO

Background: The identification of acutely ill patients at high risk for venous thromboembolism (VTE) may be determined clinically or by use of integer-based scoring systems. These scores demonstrated modest performance in external data sets. Objectives: To evaluate the performance of machine learning models compared to the IMPROVE score. Methods: The APEX trial randomized 7513 acutely medically ill patients to extended duration betrixaban vs. enoxaparin. Including 68 variables, a super learner model (ML) was built to predict VTE by combining estimates from 5 families of candidate models. A "reduced" model (rML) was also developed using 16 variables that were thought, a priori, to be associated with VTE. The IMPROVE score was calculated for each patient. Model performance was assessed by discrimination and calibration to predict a composite VTE end point. The frequency of predicted risks of VTE were plotted and divided into tertiles. VTE risks were compared across tertiles. Results: The ML and rML algorithms outperformed the IMPROVE score in predicting VTE (c-statistic: 0.69, 0.68 and 0.59, respectively). The Hosmer-Lemeshow goodness-of-fit P-value was 0.06 for ML, 0.44 for rML, and <0.001 for the IMPROVE score. The observed event rate in the lowest tertile was 2.5%, 4.8% in tertile 2, and 11.4% in the highest tertile. Patients in the highest tertile of VTE risk had a 5-fold increase in odds of VTE compared to the lowest tertile. Conclusion: The super learner algorithms improved discrimination and calibration compared to the IMPROVE score for predicting VTE in acute medically ill patients.

RESUMO

Traditional statistical models allow population based inferences and comparisons. Machine learning (ML) explores datasets to develop algorithms that do not assume linear relationships between variables and outcomes and that may account for higher order interactions to make individualized outcome predictions. To evaluate the performance of machine learning models compared to traditional risk stratification methods for the prediction of major adverse cardiovascular events (MACE) and bleeding in patients with acute coronary syndrome (ACS) that are treated with antithrombotic therapy. Data on 24,178 ACS patients were pooled from four randomized controlled trials. The super learner ensemble algorithm selected weights for 23 machine learning models and was compared to traditional models. The efficacy endpoint was a composite of cardiovascular death, myocardial infarction, or stroke. The safety endpoint was a composite of TIMI major and minor bleeding or bleeding requiring medical attention. For the MACE outcome, the super learner model produced a higher c-statistic (0.734) than logistic regression (0.714), the TIMI risk score (0.489), and a new cardiovascular risk score developed in the dataset (0.644). For the bleeding outcome, the super learner demonstrated a similar c-statistic as the logistic regression model (0.670 vs. 0.671). The machine learning risk estimates were highly calibrated with observed efficacy and bleeding outcomes (Hosmer-Lemeshow p value = 0.692 and 0.970, respectively). The super learner algorithm was highly calibrated on both efficacy and safety outcomes and produced the highest c-statistic for prediction of MACE compared to traditional risk stratification methods. This analysis demonstrates a contemporary application of machine learning to guide patient-level antithrombotic therapy treatment decisions.Clinical Trial Registration ATLAS ACS-2 TIMI 46: https://clinicaltrials.gov/ct2/show/NCT00402597.

RESUMO

BACKGROUND: Among stented patients with atrial fibrillation, double therapy with a novel oral anticoagulant plus single antiplatelet therapy (SAPT) reduces bleeding or cardiovascular rehospitalizations compared with a vitamin K antagonist (VKA) based triple therapy regimen. A recent study demonstrated that apixaban based double therapy reduced bleeding compared with VKA based double therapy. However, it remains unknown whether rivaroxaban based double therapy is superior to a VKA based double therapy. METHODS: Patient with stented atrial fibrillation (n=2124) were randomized to 3 groups: rivaroxaban 15 mg od plus a P2Y12 inhibitor (Group 1, n=709); rivaroxaban 2.5 mg bid plus dual antiplatelet therapy (DAPT; Group 2, n=709); and warfarin plus DAPT (Group 3, n=706). Before randomization, subjects were stratified according to a prespecified duration of DAPT (1, 6, or 12 months). After the prespecified DAPT duration, subjects in Group 2 were switched to rivaroxaban 15 mg plus low dose aspirin, and those in Group 3 were switched to VKA plus low dose aspirin. The Wei, Lin, and Weissfeld time to multiple events method was used to compare the occurrence of all bleeding and cardiovascular rehospitalizations among subjects on a novel oral anticoagulant versus VKA based double therapy. RESULTS: A total of 906 subjects were prespecified to a 1 or 6 months DAPT duration and received at least one dose of study drug. Twenty subjects (3.3%) assigned to novel oral anticoagulant+SAPT, and 15 (5.1%) subjects assigned to VKA+SAPT experienced multiple rehospitalizations. In total, 124 (20.3%) events occurred among subjects on novel oral anticoagulant+SAPT compared with 87 (29.6%) among subjects on VKA+SAPT (hazard ratio=0.65 [95% CI, 0.45-0.93], P=0.008). CONCLUSIONS: Among stented patients with atrial fibrillation, rivaroxaban plus SAPT was superior to warfarin plus SAPT in lowering total bleeding and cardiovascular rehospitalization.

RESUMO

OBJECTIVES: The authors sought to assess the association between admission time with patient's care, procedure characteristics, and clinical outcomes within a contemporary ST-segment elevation myocardial infarction (STEMI) network of patients referred for primary percutaneous coronary intervention (PCI). BACKGROUND: The effect of admission time on STEMI patient's outcomes remains controversial when primary PCI is the preferred reperfusion strategy. METHODS: Characteristics and clinical outcomes of 2,167 consecutive STEMI patients admitted in a tertiary PCI-capable center were collected. On-hours were defined as admission from Monday through Friday between 8 am and 6 pm and off-hours as admission during night shift, weekend, and nonworking holidays. In-hospital and 1-year all-cause mortality were assessed as well as key time delays. RESULTS: A total of 1,048 patients (48.3%) were admitted during on-hours, and 1,119 patients (51.7%) during off-hours. Characteristics were well-balanced between the 2 groups, including rates of cardiac arrest (7.9% vs. 8.8%; p = 0.55) and cardiogenic shock (12.3% vs. 14.7%; p = 0.16). Median symptom-to-first medical contact time and median first medical contact-to-sheath insertion time did not differ according to on- versus off-hours admission (120 min vs. 126 min; p = 0.25 and 90 min vs. 93 min; p = 0.58, respectively), as well as the rate of radial access for catheterization (85.6% vs. 87.5%; p = 0.27). There was no association between on- versus off-hours groups and in-hospital (8.1% vs. 7.0%; p = 0.49) or 1-year mortality (11.0% vs. 11.1%; p = 0.89), respectively. CONCLUSIONS: In a contemporary organized STEMI network, patients admitted in a high-volume tertiary primary PCI center during on-hours or off-hours had similar management and 1-year outcomes.

RESUMO

AIMS: The European Society of cardiology (ESC) EURObservational Research Programme (EORP) Chronic Ischemic Cardiovascular Disease registry Long Term (CICD) aims to study the clinical profile, treatment modalities and outcomes of patients diagnosed with CICD in a contemporary environment in order to assess whether these patients at high cardiovascular risk are treated according to ESC guidelines on prevention or on stable coronary disease and to determine mid and long term outcomes and their determinants in this population. METHODS AND RESULTS: 9174 patients over 18 years with documented CICD defined by an history acute coronary syndrome with/without ST elevation, previous coronary revascularization or stable coronary artery disease were enrolled between May 1st 2015 and July 31st 2018.Individual patient data on clinical profile, biology and treatment modalities were collected across 154 centers from 20 ESC countries.A two years follow up is scheduled in order to determine the following clinical outcomes: all cause and cardio-vascular (CV) death, all cause and cardio-vascular hospitalizations, changes in medications and quality of life using the EuroQol5D-5L score. CONCLUSION: The CICD Long Term is an international registry of care and outcomes of patients hospitalised with Chronic Ischemic Cardiovascular Disease which will provide insights into the contemporary profile and management of patients with this common disease.

RESUMO

BACKGROUND: The long-term evolution of premature coronary artery disease (CAD) is unknown. OBJECTIVES: The objective of this study was to describe the evolution of coronary atherosclerosis in young patients and identify the risk factors of poor outcomes. METHODS: Participants age ≤45 years with acute or stable obstructive CAD were prospectively enrolled and followed. The primary endpoint was all-cause death, myocardial infarction (MI), refractory angina requiring coronary revascularization, and ischemic stroke. RESULTS: Eight hundred-eighty patients with premature CAD were included. They were age 40.1 ± 5.7 years, mainly men, smokers, with a family history of CAD or hypercholesterolemia. At baseline presentation, 91.2% underwent coronary revascularization, predominantly for acute MI (78.8%). Over a follow-up of 20 years, one-third (n = 264) of patients presented with a total of 399 ischemic events, and 36% had at least a second recurrent event. MI was the most frequent first recurrent event (n = 131 of 264), mostly related to new coronary lesions (17.3% vs. 7.8%; p = 0.01; hazard ratio [HR]:1.45; 95% confidence interval [CI]: 1.09 to 1.93 for new vs. initial culprit lesion). All-cause death (n = 55; 6.3%) occurred at 8.4 years (median time). Ethnic origin (sub-Saharan African vs. Caucasian, adjusted hazard ratio [adjHR]: 1.95; 95% CI: 1.13 to 3.35; p = 0.02), inflammatory disease (adjHR: 1.58; 95% CI: 1.05 to 2.36; p = 0.03), and persistent smoking (adjHR: 2.32; 95% CI: 1.63 to 3.28; p < 0.01) were the strongest correlates of a first recurrent event. When considering all recurrent events, the same factors and Asian ethnicity predicted poor outcome, but persistent smoking had the greatest impact on prognosis. CONCLUSIONS: Premature CAD is an aggressive disease despite the currently recommended prevention measures, with high rates of recurrent events and mortality. Ethnicity and concomitant inflammatory disease are associated with poor prognoses, along with insufficient control of risk factors.

RESUMO

PURPOSE OF REVIEW: Epidemiologic studies consistently demonstrated that patients with coronary artery disease (CAD) and low HDL cholesterol (HDL-C) are more likely to develop major adverse cardiovascular events as compared with those with normal or high HDL. However, several large randomized trials failed to demonstrate that a substantial, pharmacological-based, increase of HDL-C concentrations results in a clinically significant reduction of ischemic outcomes. This has been largely attributed to the fact that, although these drugs are able to raise the HDL-C concentration, they have no effect on HDL-C atheroprotective function. Subsequently, the 'HDL hypothesis' evolved, and the focus shifted from raising the concentration of HDL-C to raising the reverse cholesterol transport (RCT) function by increasing patients cholesterol efflux capacity (CEC) instead. Indeed, new data suggest that HDL-C metabolism and the ability of the HDL molecule to transport cholesterol from the atherosclerotic plaque to the liver, measured by the CEC, is more important than steady-state HDL-C levels. Modulation of the CEC has become, therefore, a promising therapeutic target in CAD patients. This article reviews the current data on the 'cholesterol efflux hypothesis' and discuss its ability to be modulated has a potential therapeutic target. RECENT FINDINGS: Recent data have demonstrated that impaired serum CEC was associated with increased mortality after a myocardial infarction (MI). Thus, therapeutic intervention aiming to improve CEC and RCT may reduce the risk of recurrent events. Early phase clinical studies targeting CEC showed promising results and a megatrial is ongoing testing the hypothesis that an improved RCT trough a modulation of the CEC can modify patient's prognosis after an acute MI. SUMMARY: The 'cholesterol efflux hypothesis' is now supported by several clinical studies and is being tested with a therapeutic candidate in a megatrial enrolling high-risk patient with MI.

RESUMO

Background Among medically ill patients treated with thromboprophylaxis, betrixaban was not associated with an increase in major bleeding compared with enoxaparin, but an increase in clinically relevant non-major (CRNM) bleeding was observed. The aim of this analysis is to describe the severity and clinical consequences of major and CRNM bleeding in the APEX trial. Methods The APEX trial randomized 7,513 hospitalized acutely ill medical patients to receive either enoxaparin for 6 to 14 days or betrixaban for 35 to 42 days. Subjects receiving a concomitant strong p-glycoprotein inhibitor or with creatinine clearance <30 mL/min were administered a reduced dose of study drug. Results A total of 25 (0.7%) and 21 (0.6%) major bleeds occurred in the betrixaban and enoxaparin arms, respectively ( p = NS) and a total of 91 (2.5%) and 38 (1.0%) CRNM bleeds occurred in the betrixaban and enoxaparin arm ( p < 0.001), respectively. Most major bleeds were considered moderate or severe and most CRNM bleeds were considered mild and moderate ( p = NS). One fatal major bleed occurred in each treatment arm. Rates of major or CRNM bleeds resulting in new or prolonged hospitalization (major: 44.0 vs. 28.6%; CRNM: 12.1 vs. 21.1%) or study treatment interruption or cessation (major: 72.0 vs. 71.4%; CRNM: 71.3 vs. 68.4%) were similar between treatment arms ( p = NS). Conclusions In the APEX trial, CRNM bleeds were mild or moderate in nature and had less of a clinical impact than major bleeds. The severity and clinical sequela of bleeds in the betrixaban arm were comparable to those in the enoxaparin arm.

RESUMO

ST-segment elevation myocardial infarction (STEMI) is the most acute manifestation of coronary artery disease and is associated with great morbidity and mortality. A complete thrombotic occlusion developing from an atherosclerotic plaque in an epicardial coronary vessel is the cause of STEMI in the majority of cases. Early diagnosis and immediate reperfusion are the most effective ways to limit myocardial ischaemia and infarct size and thereby reduce the risk of post-STEMI complications and heart failure. Primary percutaneous coronary intervention (PCI) has become the preferred reperfusion strategy in patients with STEMI; if PCI cannot be performed within 120 minutes of STEMI diagnosis, fibrinolysis therapy should be administered to dissolve the occluding thrombus. The initiation of networks to provide around-the-clock cardiac catheterization availability and the generation of standard operating procedures within hospital systems have helped to reduce the time to reperfusion therapy. Together with new advances in antithrombotic therapy and preventive measures, these developments have resulted in a decrease in mortality from STEMI. However, a substantial amount of patients still experience recurrent cardiovascular events after STEMI. New insights have been gained regarding the pathophysiology of STEMI and feed into the development of new treatment strategies.

RESUMO

Large registries and epidemiologic studies have demonstrated that elderly patients (≥ 75 years old) represent a growing proportion of the acute coronary syndrome (ACS) population and are exposed to a high risk of both bleeding and ischemic events. In this setting, most of the randomized trials excluded elderly patients while evaluating therapeutic strategies in ACS and only few trials specifically dedicated their design to the elderly population, leading to a paucity of data. Elderly patients are less likely to be treated with an invasive strategy or potent antithrombotic drugs compared with younger patients, while they are exposed to a greater risk of mortality. Nevertheless, the benefit of an invasive approach in ST-segment elevation myocardial infarction (STEMI) has been consistently demonstrated in non-dedicated large percutaneous coronary intervention randomized trials, regardless of the patient's age. European clinical practice guidelines recommend that STEMI in elderly patients should not be treated differently than in younger patients. However, the therapeutic decision should be based on a combined evaluation of both (1) the patient's frailty, including functional or cognitive impairment, and (2) the balance between bleeding and ischemic risks. This review outlines the evidence on the optimal reperfusion and antithrombotic strategies among STEMI elderly patients, suggesting a patient-centered approach to apprehend the balanced therapeutic decision in the very old patient.

RESUMO

PURPOSE OF REVIEW: The last 40 years of clinical research in interventional cardiology were extraordinarily innovative. This article will review the most promising up and coming interventional cardiovascular therapies, with a primary focus on the treatment of coronary artery disease. RECENT FINDINGS: From the first stent, to the first transcatheter aortic valve implantation (TAVI), and the left appendage closure technique, percutaneous interventions revolutionized the treatment of multiple diseases and dramatically improved the prognosis of many patients. While these advances have decreased the risk of mortality in some patients (such as ST-elevation myocardial infarction), 15% of acute coronary syndrome (ACS) patients still experience recurrent ischemic events within the first year, challenging us to develop new pharmaceutical targets and new devices. The continued emergence of data supporting inflammation as a risk factor and pharmacologic target as well as data supporting the importance of cholesterol efflux have identified novel therapeutic targets that may play a major role in the improvement of prognosis of patients with coronary artery disease. In addition, novel medical devices are being developed to allow even earlier detection of acute cardiac events and to support high-risk percutaneous coronary interventions. Advances in computing and the ability to analyze large datasets will allow us to use artificial intelligence to augment the clinician patient experience, both in and out of the catheterization laboratory, with live procedural guidance as well as pre- and post-operative prognostication tools.

RESUMO

The lifelong use of ß-adrenoceptor antagonists (ß-blockers) after a myocardial infarction (MI) has been the standard of care based on trials performed before the era of revascularization, when heart failure was common. Large randomized trials in the mid-1980s demonstrated that ß-blockers played a major role in improving the in-hospital and long-term survival of patients admitted for MI. However, the implementation of rapid myocardial reperfusion led to a substantial survival benefit and a reduction of heart failure because of reduced infarct size. Modern large longitudinal registries did not provide sufficient evidence to support long-term ß-blocker therapy in patients with uncomplicated acute MI. The long-term prescription of this therapy has become a matter of debate given the lack of contemporary evidence, frequent side effects, and treatment adherence issues. Furthermore, this shift into the reperfusion era led to a downgraded recommendation for the use of ß-blockers in post-MI patients (class IIa B recommendation) in the 2017 European Society of Cardiology (ESC) recommendations for the treatment of ST-segment elevation MI (STEMI). Three large ongoing multicenter randomized trials (AßYSS, REDUCE-SWEDEHEART, and REBOOT-CNIC) are evaluating early discontinuation of ß-blockers after an uncomplicated acute MI. The tested hypothesis is that ß-blocker withdrawal is safe versus major adverse cardiovascular events and improves quality of life by reducing side effects. Thus, the present review summarizes the exhaustive evidence-based data for long-term ß-blocker use after uncomplicated MI and the ongoing trials.

RESUMO

BACKGROUND: Among atrial fibrillation patients undergoing percutaneous coronary intervention enrolled in PIONEER AF-PCI (An Open-Label, Randomized, Controlled, Multicenter Study Exploring Two Treatment Strategies of Rivaroxaban and a Dose-Adjusted Oral Vitamin K Antagonist Treatment Strategy in Subjects With Atrial Fibrillation Who Undergo Percutaneous Coronary Intervention), it is unclear if the observed reduction in bleeding events with rivaroxaban regimens is consistent across a range of the international normalized ratio (INR) among subjects administrated Vitamin K antagonist (VKA)-triple therapy. This analysis compares the occurrence of clinically significant bleeding between rivaroxaban and VKA strategies, according to INR stability of subjects administrated VKA. METHODS AND RESULTS: A total of 2124 atrial fibrillation patients undergoing percutaneous coronary intervention were randomized to 3 groups: rivaroxaban 15 mg od plus a P2Y12 inhibitor (group 1, n=709); rivaroxaban 2.5 mg bid plus dual antiplatelet therapy (group 2, n=709); and warfarin plus dual antiplatelet therapy (group 3, n=706). Subjects assigned to the VKA group were stratified according to time in therapeutic range and time spent with an INR >3. Kaplan-Meier estimates were calculated for clinically significant bleeding through 1 year and hazard ratios were derived using Cox Proportional Hazards models. Among group 3, 93.4% of the participants had a time in therapeutic range available (mean time in therapeutic range=65.0±24.8%). Both groups 1 and 2 were associated with a reduction in clinically significant bleeding compared with subjects in group 3, regardless of the time in therapeutic range (hazard ratio ranges=0.53-0.71 and 0.57-0.76; respectively, P<0.05 for all). Rivaroxaban strategies were associated with a reduction in clinically significant bleeding compared with VKA regardless of the proportion of time spent with an INR >3 (hazard ratio ranges=0.59-0.67 and 0.42-0.69; P<0.05 for all). CONCLUSIONS: Among atrial fibrillation patients undergoing percutaneous coronary intervention, rivaroxaban-based therapy was superior to warfarin plus dual antiplatelet therapy in lowering bleeding outcomes regardless of the INR stability.

RESUMO

BACKGROUND: Two biomarkers of early acute kidney injury-plasmatic neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C-are not used in routine clinical practice in patients with ST-segment elevation myocardial infarction (STEMI) treated by percutaneous coronary intervention (PCI) because of a lack of supporting data. AIMS: To evaluate the predictive value of NGAL and cystatin C regarding the incidence of contrast-induced acute kidney injury (CI-AKI) and clinical outcomes after STEMI in patients treated by primary PCI. METHODS: Plasmatic NGAL and cystatin C were measured on admission, before any contrast exposure, in 701 unselected patients with STEMI. Associations between biomarker concentrations and incidence of CI-AKI (assessed at 48h), haemodialysis requirement at 1 year and all-cause mortality at 1 year were assessed by logistic regression analyses and receiver operating characteristic area under the curve analysis (c-statistic). Discrimination performance comparison was performed using the DeLong test. RESULTS: NGAL and cystatin C had mild discrimination regarding CI-AKI, with c-statistics of 0.60 (P=0.001) and 0.60 (P=0.002), respectively. Combining NGAL and cystatin C did not improve their discrimination (c-statistic 0.61; P=0.001). There was no significant difference in discrimination between NGAL, cystatin C and baseline creatinine (P=0.57). Regression analyses showed no independent association between NGAL and CI-AKI, haemodialysis or 1-year mortality. Similarly, cystatin C was not associated with these clinical outcomes. CONCLUSIONS: In this cohort of patients with STEMI treated by primary PCI, plasmatic NGAL and cystatin C did not provide additional value regarding CI-AKI prediction compared with known risk factors such as baseline creatinine.

RESUMO

BACKGROUND: Copeptin - the C-terminal section of vasopressin precursor - is a novel biomarker, that has been shown to be a useful prognostic factor in heart failure, ischemic stroke and in acute myocardial infarction (MI) but with restricted population and follow-up in ST-segment elevation MI (STEMI) setting. We evaluated in this study the hypothesis that copeptin measured on admission is an independent predictor of one-year all-cause mortality after a STEMI. METHODS: Copeptin was measured immediately on arrival in the catheterization laboratory in a cohort of unselected STEMI patients and was compared to the peak of cardiac troponin I as a prognosis marker. One-year follow-up was performed. RESULTS: We included 401 STEMI patients (77% of men, mean age 64 ±â€¯14 years) treated by primary percutaneous coronary intervention. Copeptin on admission was significantly higher in patients who died during the one-year follow-up than in survivors (154.8 pmol/L; IQR [63.9-304.8] vs 30.3 pmol/L; IQR [10.8-93.5]); p < 0.0001). There was an increase in mortality at one year from the lowest to the highest quartile of copeptin. After Cox regression analysis, copeptin was an independent predictor of death at one year (adjHR 3.1, 95% CI [1.5-6.2], p = 0.001). When compared to the peak value of cardiac troponin I, copeptin measured on admission had a better prognostic value to predict one-year mortality (AUC of 0.74 vs 0.60, p = 0.022). CONCLUSION: Copeptin measured on admission is a reliable and independent prognostic biomarker of one-year mortality in acute myocardial infarction patients.
