RESUMO

Interest in the use of mechanical circulatory support for patients presenting with cardiogenic shock is growing rapidly. The Impella (Abiomed Inc), a microaxial, continuous-flow, short-term, ventricular assist device (VAD), requires meticulous postimplantation management. Because systemic anticoagulation is needed to prevent pump thrombosis, patients are exposed to increased bleeding risk, further aggravated by sepsis, thrombocytopenia, and high shear stress-induced acquired von Willebrand syndrome. The precarious balance between bleeding and thrombosis in percutaneous VAD-supported cardiogenic shock patients is often the main reason that patient outcomes are jeopardized, and there is a lack of data addressing optimal anticoagulation management strategies during percutaneous VAD support. Here, we present a parallel anti-Factor Xa/activated partial thromboplastin time-guided anticoagulation algorithm and discuss pitfalls of heparin monitoring in critically ill patients. This review will guide physicians toward a more standardized (anti)coagulation approach to tackle device-related morbidity and mortality in this critically ill patient group.

RESUMO

Since optical coherence tomography (OCT) was first performed in humans two decades ago, this imaging modality has been widely adopted in research on coronary atherosclerosis and adopted clinically for the optimization of percutaneous coronary intervention. In the past 10 years, substantial advances have been made in the understanding of in vivo vascular biology using OCT. Identification by OCT of culprit plaque pathology could potentially lead to a major shift in the management of patients with acute coronary syndromes. Detection by OCT of healed coronary plaque has been important in our understanding of the mechanisms involved in plaque destabilization and healing with the rapid progression of atherosclerosis. Accurate detection by OCT of sequelae from percutaneous coronary interventions that might be missed by angiography could improve clinical outcomes. In addition, OCT has become an essential diagnostic modality for myocardial infarction with non-obstructive coronary arteries. Insight into neoatherosclerosis from OCT could improve our understanding of the mechanisms of very late stent thrombosis. The appropriate use of OCT depends on accurate interpretation and understanding of the clinical significance of OCT findings. In this Review, we summarize the state of the art in cardiac OCT and facilitate the uniform use of this modality in coronary atherosclerosis. Contributions have been made by clinicians and investigators worldwide with extensive experience in OCT, with the aim that this document will serve as a standard reference for future research and clinical application.

RESUMO

OBJECTIVES: The purpose of this study was to assess the extent to which the association between premature dual antiplatelet therapy (DAPT) discontinuation and excess risk of thrombotic events varies according to the reason and timing of DAPT discontinuation and whether high on-treatment platelet reactivity (HPR) influences the risk of thrombotic events after premature DAPT discontinuation. BACKGROUND: DAPT after percutaneous coronary intervention (PCI) suppresses platelet reactivity, and HPR on clopidogrel after PCI is associated with an increased risk of thrombotic events. METHODS: ADAPT-DES (Assessment of Dual Antiplatelet Therapy With Drug-Eluting Stents) was a prospective, multicenter registry of 8,582 patients successfully treated with coronary drug-eluting stents that assessed HPR on clopidogrel. For patients who discontinued aspirin or clopidogrel at any time during the study, the reasons for discontinuation were systematically categorized. RESULTS: Planned DAPT discontinuation occurred within 2 years in 3,203 (37.3%) patients. One thousand four hundred eighteen (16.5%) patients discontinued DAPT for unplanned reasons, including surgery or trauma (n = 768 [8.9%]), patient nonadherence (n = 321 [3.7%]), bleeding complications (n = 264 [3.1%]), and drug allergy or hypersensitivity (n = 113 [1.3%]). Unplanned but not planned DAPT discontinuation was associated with an increased risk of a major adverse cardiac event (MACE, defined as the composite of cardiac death, myocardial infarction, or stent thrombosis); with highest risk within 3 months after PCI (adjusted HR: 7.65, 95% CI: 2.77-21.10 vs adjusted HR: 2.47, 95% CI: 1.70-3.58 for unplanned DAPT discontinuation ≥3 weeks after PCI). MACE risk after DAPT discontinuation was not moderated by HPR (Pinteraction = 0.91). CONCLUSIONS: In this large-scale all-comers registry, premature DAPT discontinuation for unplanned reasons occurred in approximately 1 of 6 patients after DES implantation and was associated with a markedly increased risk of MACEs.

RESUMO

Background In participants with concomitant chronic coronary disease and advanced chronic kidney disease (CKD), the effect of treatment strategies on the timing of dialysis initiation is not well characterized. Methods and Results In ISCHEMIA-CKD (International Study of Comparative Health Effectiveness With Medical and Invasive Approaches-Chronic Kidney Disease), 777 participants with advanced CKD and moderate or severe ischemia were randomized to either an initial invasive or conservative management strategy. Herein, we compare the proportion of randomized participants with non-dialysis-requiring CKD at baseline (n=362) who initiated dialysis and compare the time to dialysis initiation between invasive versus conservative management arms. Using multivariable Cox regression analysis, we also sought to identify the effect of invasive versus conservative chronic coronary disease management strategies on dialysis initiation. At a median follow-up of 23 months (25th-75th interquartile range, 14-32 months), dialysis was initiated in 18.9% of participants (36/190) in the invasive strategy and 16.9% of participants (29/172) in the conservative strategy (P=0.22). The median time to dialysis initiation was 6.0 months (interquartile range, 3.0-16.0 months) in the invasive group and 18.2 months (interquartile range, 12.2-25.0 months) in the conservative group (P=0.004), with no difference in procedural acute kidney injury rates between the groups (7.8% versus 5.4%; P=0.26). Baseline clinical factors associated with earlier dialysis initiation were lower baseline estimated glomerular filtration rate (hazard ratio [HR] associated with 5-unit decrease, 2.08 [95% CI, 1.72-2.56]; P<0.001), diabetes (HR, 2.30 [95% CI, 1.28-4.13]; P=0.005), hypertension (HR, 7.97 [95% CI, 1.09-58.21]; P=0.041), and Hispanic ethnicity (HR, 2.34 [95% CI, 1.22-4.47]; P=0.010). Conclusions In participants with non-dialysis-requiring CKD in ISCHEMIA-CKD, randomization to an invasive chronic coronary disease management strategy (relative to a conservative chronic coronary disease management strategy) is associated with an accelerated time to initiation of maintenance dialysis for kidney failure.

RESUMO

BACKGROUND: ISCHEMIA (International Study of Comparative Health Effectiveness with Medical and Invasive Approaches) compared an initial invasive treatment strategy (INV) with an initial conservative strategy in 5179 participants with chronic coronary disease and moderate or severe ischemia. The ISCHEMIA research program included a comprehensive quality-of-life (QOL) substudy. METHODS: In 1819 participants (907 INV, 912 conservative strategy), we collected a battery of disease-specific and generic QOL instruments by structured interviews at baseline; at 3, 12, 24, and 36 months postrandomization; and at study closeout. Assessments included angina-related QOL (19-item Seattle Angina Questionnaire), generic health status (EQ-5D), depressive symptoms (Patient Health Questionnaire-8), and, for North American patients, cardiac functional status (Duke Activity Status Index). RESULTS: Median age was 67 years, 19.2% were female, and 15.9% were non-White. The estimated mean difference for the 19-item Seattle Angina Questionnaire Summary score favored INV (1.4 points [95% CI, 0.2-2.5] over all follow-up). No differences were observed in patients with rare/absent baseline angina (SAQ Angina Frequency score >80). Among patients with more frequent angina at baseline (SAQ Angina Frequency score <80, 744 patients, 41%), those randomly assigned to INV had a mean 3.7-point higher 19-item Seattle Angina Questionnaire Summary score than conservative strategy (95% CI, 1.6-5.8) with consistent effects across SAQ subscales: Physical Limitations 3.2 points (95% CI, 0.2-6.1), Angina Frequency 3.2 points (95% CI, 1.2-5.1), Quality of Life/Health Perceptions 5.3 points (95% CI, 2.8-7.8). For the Duke Activity Status Index, no difference was estimated overall by treatment, but in patients with baseline SAQ Angina Frequency scores <80, Duke Activity Status Index scores were higher for INV (3.2 points [95% CI, 0.6-5.7]), whereas patients with rare/absent baseline angina showed no treatment-related differences. Moderate to severe depression was infrequent at randomization (11.5%-12.8%) and was unaffected by treatment assignment. CONCLUSIONS: In the ISCHEMIA comprehensive QOL substudy, patients with more frequent baseline angina reported greater improvements in the symptom, physical functioning, and psychological well-being dimensions of QOL when treated with an invasive strategy, whereas patients who had rare/absent angina at baseline reported no consistent treatment-related QOL differences.

RESUMO

The clinical implications of hypertension in addition to a high prevalence of both uncontrolled blood pressure and medication nonadherence promote interest in developing device-based approaches to hypertension treatment. The expansion of device-based therapies and ongoing clinical trials underscores the need for consistency in trial design, conduct, and definitions of clinical study elements to permit trial comparability and data poolability. Standardizing methods of blood pressure assessment, effectiveness measures beyond blood pressure alone, and safety outcomes are paramount. The Hypertension Academic Research Consortium (HARC) document represents an integration of evolving evidence and consensus opinion among leading experts in cardiovascular medicine and hypertension research with regulatory perspectives on clinical trial design and methodology. The HARC document integrates the collective information among device-based therapies for hypertension to better address existing challenges and identify unmet needs for technologies proposed to treat the world's leading cause of death and disability. Consistent with the Academic Research Consortium charter, this document proposes pragmatic consensus clinical design principles and outcomes definitions for studies aimed at evaluating device-based hypertension therapies.

RESUMO

OBJECTIVES: This study sought to determine correlates and consequences of contrast-associated acute kidney injury (CA-AKI) on clinical outcomes in patients with or without pre-existing chronic kidney disease (CKD). BACKGROUND: The incidence and impact of CA-AKI on clinical outcomes during contemporary percutaneous coronary intervention (PCI) are not fully defined. METHODS: The ADAPT-DES (Assessment of Dual AntiPlatelet Therapy With Drug Eluting Stents) study was a prospective, multicenter registry of 8,582 patients treated with ≥1 drug-eluting stent(s). CA-AKI was defined as a post-PCI increase in serum creatinine of >0.5 mg/dL or a relative increase of ≥25% compared with pre-PCI. CKD was defined as estimated glomerular filtration rate <60 mL/min/1.73 m2. The primary endpoint was the 2-year rate of net adverse clinical events (NACE): All-cause mortality, myocardial infarction (MI), definite or probable stent thrombosis, or major bleeding. RESULTS: Of 7287 (85%) patients with evaluable data, 476 (6.5%) developed CA-AKI. In a multivariable model, older age, female sex, Caucasian race, congestive heart failure, diabetes, hypertension, CKD, presentation with ST-segment elevation MI, Killip class II to IV, radial access, intra-aortic balloon pump use, hypotension, and number of stents were independent predictors of CA-AKI. The 2-year NACE rate was higher in patients with CA-AKI (adjusted HR: 1.88; 95% CI: 1.42-2.49), as was each component of NACE (all-cause mortality, HR: 1.77; 95% CI: 1.22-2.55; MI, HR: 1.67; 95% CI: 1.18-2.36; definite/probable stent thrombosis, HR: 1.71; 95% CI: 1.10-2.65; and major bleeding, HR: 1.38; 95% CI: 1.06-1.80). Compared with the CA-AKI-/CKD- group, the CA-AKI+/CKD- (HR: 1.83; 95% CI: 1.33-2.52), CA-AKI-/CKD+ (HR: 1.56; 95% CI: 1.15-2.13), CA-AKI+/CKD+ (HR: 3.29; 95% CI: 1.92-5.67), and maintenance dialysis (HR: 2.67; 95% CI: 1.65-4.31) groups were at higher risk of NACE. CONCLUSIONS: CA-AKI was relatively common after contemporary PCI and was associated with increased 2-year rates of NACE. Patients with pre-existing CKD were at particularly high risk for NACE after CA-AKI.

RESUMO

BACKGROUND: Severe coronary artery calcification has been associated with stent underexpansion, procedural complications, and increased rates of early and late adverse clinical events in patients undergoing percutaneous coronary intervention. To date, no lesion preparation strategy has been shown to definitively improve outcomes of percutaneous coronary intervention for calcified coronary artery lesions. STUDY DESIGN AND OBJECTIVES: ECLIPSE (NCT03108456) is a prospective, randomized, multicenter trial designed to evaluate two different vessel preparation strategies in severely calcified coronary artery lesions. The routine use of the Diamondback 360 Coronary Orbital Atherectomy System is compared with conventional balloon angioplasty prior to drug-eluting stent implantation. The trial aims to enroll approximately 2000 subjects with a primary clinical endpoint of target vessel failure, defined as the composite of cardiac death, target vessel-related myocardial infarction, or ischemia-driven target vessel revascularization assessed at 1 year. The co-primary endpoint is the acute post-procedural in-stent minimal cross-sectional area as assessed by optical coherence tomography in a 500-subject cohort. Enrollment is anticipated to complete in 2022 with total clinical follow-up planned for 2 years. CONCLUSIONS: ECLIPSE is a large-scale, prospective randomized trial powered to demonstrate whether a vessel preparation strategy of routine orbital atherectomy system is superior to conventional balloon angioplasty prior to implantation of drug-eluting stents in severely calcified coronary artery lesions.

RESUMO

BACKGROUND: Diabetes mellitus (DM) is an important predictor of neointimal hyperplasia (NIH) and adverse clinical outcomes after percutaneous coronary intervention (PCI). LABR-312, a novel intravenous formulation of liposomal alendronate, has been shown in animal models to decrease NIH at vascular injury sites and around stent struts. The aim of the Biorest Liposomal Alendronate Administration for Diabetic Patients Undergoing Drug-Eluting Stent Percutaneous Coronary Intervention trial was to assess the safety, effectiveness, and dose response of LABR-312 administered intravenously at the time of PCI withDES in reducing NIH as measured by optical coherence tomography postprocedure in patients with DM. METHODS: Patients with DM were randomized to a bolus infusion of LABR-312 vs placebo at the time of PCI. Dose escalation of LABR-312 in the study arm was given: 0.01 mg, 0.03 mg, and 0.08 mg. The primary endpoint was the in-stent %NIH volume at 9 months as measured by optical coherence tomography. RESULTS: From September 2016 to December 2017, 271 patients with DM undergoing PCI were enrolled; 136 patients were randomized to LABR-312 infusion and 135 patients were randomized to placebo. At 9-month follow-up, no difference was seen in the primary endpoint of %NIH between LABR-312 and placebo (13.3% ± 9.2 vs 14.6% ± 8.5, P = .35). No differences were present with the varying LABR-312 doses. Clinical outcomes at 9 months were similar between groups. CONCLUSIONS: Among patients with DM undergoing PCI with drug-eluting stents, a bolus of LABR-312 injected systematically at the time of intervention did not result in a lower rate in-stent %NIH volume at 9-month follow-up.

RESUMO

BACKGROUND: We investigated outcomes of CABG with endoscopic (EVH) versus open vein harvest (OVH) within the Evaluation of XIENCE versus CABG (EXCEL) Trial. METHODS: All patients in EXCEL randomized to CABG were included in this study. For this analysis, the primary endpoints were ischemia-driven revascularization, and graft stenosis or occlusion at 5 years. Additional endpoints were: a composite of death from any cause, stroke, or MI; bleeding; blood product transfusion; major arrhythmia; and infection requiring antibiotics. Event rates were based on Kaplan-Meier estimates in time-to-first-event analyses. RESULTS: Of the 957 patients randomized to CABG, 686 (71.7%) received at least one venous graft with 257 (37.5%) patients in the EVH group and 429 (62.5%) patients in the OVH group. At 5 years, ischemia-driven revascularization was higher (11.5% vs. 6.7%, P=.047) in the EVH group. At 5 years, rates of graft stenosis or occlusion (9.7% vs. 5.4%, P=.054), and the primary endpoint (17.4% vs. 20.9%, P=.27) were similar. In-hospital bleeding (11.3% vs. 13.8%, P=.35), in-hospital blood product transfusion (12.8% vs. 13.1%, P=.94), and infection requiring antibiotics within 1 month (13.6% vs. 16.8%, P=.27) were similar between EVH and OVH patients. Major arrhythmia in-hospital (19.8% vs. 13.5%, P=.03) and within 1 month (21.8% vs. 15.4%, P=.03) were higher in EVH patients. CONCLUSIONS: Ischemia-driven revascularization at 5 years was higher in the EVH group. EVH and OVH patients had similar rates of graft stenosis or occlusion, and composite of death, stroke, or MI at 5 years.

RESUMO

OBJECTIVES: To assess coronary orbital atherectomy (OA) use in Hispanic or Latino (HL) patients compared to non-HL patients. BACKGROUND: HL patients are at greater risk of cardiovascular disease mortality compared with Whites with similar coronary artery calcium (CAC) scores. The safety and efficacy of coronary atherectomy in the HL patient population is unknown due to the under-representation of minorities in clinical trial research. METHODS: A retrospective analysis of consecutive patients undergoing coronary OA treatment of severely calcified lesions at the Mount Sinai Medical Center, Miami Beach, Florida (MSMCMB) was completed. From January 2014 to September 2020, a total of 609 patients from MSMCMB who underwent percutaneous coronary intervention with OA were identified in the electronic health records. RESULTS: Of those identified, 350 (57.5%) had an ethnicity classification of HL. The overall mean age was 74 years and there was a high prevalence of diabetes in the HL group compared to the non-HL group (49.7% vs. 34.7%; p = 0.0003). Severe angiographic complications were uncommon and in-hospital freedom from major adverse cardiac events (MACE), a composite of cardiac death, MI, and stroke (ischemic or hemorrhagic cerebrovascular accidents), was 98.5% overall, with no significant difference between the HL and non-HL groups, despite the higher prevalence of diabetes in the HL group. CONCLUSIONS: This study represents the largest real-world experience of OA use in HL versus non-HL patients. The main finding in this retrospective analysis is that OA can be performed safely and effectively in a high-risk population of HL patients.

RESUMO

Clinical, laboratory, and autopsy findings support an association between coronavirus disease-2019 (COVID-19) and thromboembolic disease. Acute COVID-19 infection is characterized by mononuclear cell reactivity and pan-endothelialitis, contributing to a high incidence of thrombosis in large and small blood vessels, both arterial and venous. Observational studies and randomized trials have investigated whether full-dose anticoagulation may improve outcomes compared with prophylactic dose heparin. Although no benefit for therapeutic heparin has been found in patients who are critically ill hospitalized with COVID-19, some studies support a possible role for therapeutic anticoagulation in patients not yet requiring intensive care unit support. We summarize the pathology, rationale, and current evidence for use of anticoagulation in patients with COVID-19 and describe the main design elements of the ongoing FREEDOM COVID-19 Anticoagulation trial, in which 3,600 hospitalized patients with COVID-19 not requiring intensive care unit level of care are being randomized to prophylactic-dose enoxaparin vs therapeutic-dose enoxaparin vs therapeutic-dose apixaban. (FREEDOM COVID-19 Anticoagulation Strategy [FREEDOM COVID]; NCT04512079).

RESUMO

BACKGROUND: In randomized trials, cangrelor reduced periprocedural ischemic events related to percutaneous coronary intervention without increasing GUSTO severe bleeding. However, some antiplatelet agents have shown a differential treatment effect by body mass index (BMI). METHODS: Patients from the 3 CHAMPION trials (Cangrelor Versus Standard Therapy to Achieve Optimal Management of Platelet Inhibition) who were randomized to cangrelor versus clopidogrel during percutaneous coronary intervention were stratified by BMI. The primary efficacy end point was a composite of death, myocardial infarction, ischemia-driven revascularization, or stent thrombosis within 48 hours. The principal safety outcome was GUSTO moderate or severe bleeding at 48 hours, although more sensitive bleeding measures such as Thrombolysis in Myocardial Infarction major bleeding were also assessed. We examined obese patients (defined as BMI≥30) versus nonobese patients. RESULTS: There were 24 893 patients, with 8979 (36.1%) having BMI of ≥30. There was no significant difference in the primary efficacy end point among obese versus nonobese patients (4.3% versus 4.2%; rate ratio, 1.01 [95% CI, 0.89-1.15]; P=0.82). There was a consistent benefit in the primary efficacy end point in patients who received cangrelor versus placebo who were obese (3.9% versus 4.7%, rate ratio, 0.83 [95% CI, 0.68-1.02]; P=0.07) and not obese (3.8% versus 4.7%; rate ratio, 0.81 [95% CI, 0.69-0.94]; P=0.0053); interaction P=0.77. There was no difference in GUSTO moderate or severe bleeding among patients who received cangrelor versus placebo who were obese (0.6% versus 0.6%; rate ratio, 0.99 [95% CI, 0.58-1.67]; P=0.96). CONCLUSIONS: Cangrelor at the time of percutaneous coronary intervention is effective and safe in obese and nonobese patients. There was no difference in short-term efficacy between obese and nonobese patients. Periprocedural cangrelor is an effective and safe antiplatelet agent, irrespective of BMI.
