Prevalence and prognostic impact of hsCRP elevation are age-dependent in women but not in men undergoing percutaneous coronary intervention.

BACKGROUND: High-sensitivity C-reactive protein (hsCRP) predicts outcomes after percutaneous coronary intervention (PCI). OBJECTIVE: We studied the prevalence and prognostic impact of hsCRP elevation according to age in men and women undergoing PCI. METHODS: We included patients undergoing PCI at our center from 2010 until 2017, excluding those with myocardial infarction (MI) on presentation, neoplastic disease and hsCRP >10 mg/L at baseline. Elevated hsCRP was defined as >3 mg/L. The outcome of interest was major adverse cardiac events (MACE) consisting of all-cause death, MI and target vessel revascularization. The association between hsCRP elevation and outcomes was assessed using adjusted Cox models. RESULTS: 10,432 men and 4,345 women were included. Elevation of hsCRP was present in 25.7% of men and 37.0% of women (p < .01). In men, prevalence of hsCRP elevation was stable across age strata (ptrend  = .42). In women, hsCRP elevation was most prevalent in patients <50 years (44.6%) and decreased stepwise with increasing age (ptrend < .001). After stratifying the population into age quartiles (Q1: <59 years, Q2: 59-66 years, Q3: 67-74 years, Q4: ≥75 years), hsCRP elevation was associated with increased risk of MACE across all age groups in men (HR [95% CI] Q1: 1.49 [1.12-1.98]; Q2: 1.51 [1.21-2.06]; Q3: 1.76 [1.27-2.51]; Q4: 1.43[1.03-1.97]). In women, hsCRP elevation was associated with increased risk of MACE only among older patients (HR [95% CI] Q1: 1.08 [0.64-0.82]; Q2: 1.52 [0.93-2.46]; Q3: 1.65 [1.08-2.50]; Q4: 1.52 [1.02-1.28]). CONCLUSION: Among patients undergoing PCI, prevalence and prognostic value of hsCRP elevation were age-dependent exclusively in women.

Comparative influence of bleeding and ischemic risk factors on diabetic patients undergoing percutaneous coronary intervention with everolimus-eluting stents.

OBJECTIVE: To investigate the impact of ischemic and bleeding risk factors on long-term clinical outcomes of patients with diabetes mellitus (DM) undergoing percutaneous coronary intervention (PCI) with everolimus-eluting stents. BACKGROUND: Second-generation drug-eluting stents have substantially improved outcomes after PCI in the general population; however, DM patients continue to experience high rates of ischemic and bleeding complications. METHODS: DM patients from the pooled XIENCE V registry were divided into high or low bleeding and ischemic risk groups (HBR, LBR, HIR, and LIR) based on established bleeding (age ≥ 75 years; chronic kidney disease; anemia; prior stroke; oral anticoagulation; thrombocytopenia; prior major bleeding) and ischemic (acute coronary syndrome; prior myocardial infarction [MI]; ≥3 stents implanted; ≥3 vessels treated; ≥3 lesions treated; stent length > 60 mm; bifurcation treated with ≥2 stents; chronic total occlusion) risk factors. The primary outcomes were major adverse cardiac events (MACE; cardiac death, MI, or stent thrombosis) and major bleeding at 4-year follow-up. RESULTS: A total of 3,704 DM patients were divided into four groups (21.5% LBR/LIR; 39.0% LBR/HIR; 15.6% HBR/LIR; 23.9% HBR/HIR). Compared with LBR/LIR patients, those at HBR/HIR and HBR/LIR had a significantly higher risk of MACE (HR (95% CI) 2.7 (1.9-3.9) and 2.2 (1.5-3.2), respectively) and major bleeding (2.7 (1.6-4.8) and 2.6 (1.4-4.7), respectively), while LBR/HIR patients did not. CONCLUSIONS: Among DM patients undergoing PCI, presence of bleeding risk factors was associated with a higher risk of both ischemic and bleeding events, whereas commonly used features of ischemic risk did not impact long-term clinical outcomes.

One-year clinical outcomes in patients with chronic kidney disease treated with COMBO stents: From the COMBO collaboration.

BACKGROUND: Chronic kidney disease (CKD) patients undergoing percutaneous coronary intervention (PCI) experience greater ischemic events including clinically driven target lesion revascularization (CD-TLR). Whether the COMBO biodegradable-polymer sirolimus-eluting stent promotes better outcomes in these patients by virtue of endothelial progenitor cell capture technology is unknown. OBJECTIVE: We examined one-year outcomes by CKD status from the COMBO collaboration. METHODS: The COMBO collaboration was a patient-level pooled dataset from the REMEDEE and MASCOT registries (3,614 patients) of all-comers undergoing attempted COMBO stent PCI. The primary endpoint was one-year target lesion failure (TLF), composite of cardiac death, target-vessel myocardial infarction (TV-MI) or CD-TLR. Secondary endpoints included stent thrombosis (ST). RESULTS: The study included 6.4% (n = 231) CKD and 93.6% (n = 3,361) non-CKD patients. CKD patients were older and included more women with greater prevalence of several comorbidities but similar rate of acute coronary syndrome (50.6% vs. 54.5%, p = .26). CKD patients underwent radial PCI less often (56.1% vs. 70.3%, p < .001) and received clopidogrel (78.6% vs. 68.3%) more often (p = .004). One-year TLF occurred in 7.9% CKD vs. 3.7% non-CKD patients, p = .001. CKD patients also demonstrated greater incidence of cardiac death (6.2% vs. 1.2%, p < .0001), TV-MI (2.7% vs. 1.1%, p = .04) but similar CD-TLR (2.7% vs 2.2%, p = .61) and definite/probable ST (1.4% vs. 0.8%, p = .42), compared to non-CKD patients. CONCLUSIONS: CKD patients treated with COMBO stents had significantly greater incidence of one-year TLF compared to non-CKD patients driven by cardiac death and to a lesser extent TV-MI but not CD-TLR. They had similar rates of definite/probable ST.

Association of Functional Status and Symptom Severity Among Patients Who Received Palliative Care Consultations.

Background: The relationship between functional status and the severity of different symptoms in patients with serious illnesses has not been explored in detail. Methods: We retrospectively evaluated registry data of hospitalized patients who received inpatient palliative care consults at the Mount Sinai Health System between January 01, 2020, and December 31, 2022. The registry was approved by the local institutional review board. During the initial consult, palliative care clinicians administered the Australia-modified Karnofsky Performance Status (KPS) and the Edmonton Symptom Assessment System (ESAS). We extracted these measures and other variables of interest from electronic health records and billing data, and assessed the association of functional status and symptom severity for different symptoms using ordinal logistic regression models. Results: The study included 9800 patients who received a palliative care consult. When modeling the association of functional status and the severity of different symptoms, two distinct groups of symptoms emerged: Nausea, physical discomfort, anxiety, depression, and constipation were more prevalent and severe among patients with higher functional status. Conversely, drowsiness, inactivity, dyspnea, anorexia, and agitation were more prevalent and severe among patients with lower functional status. These findings remained statistically significant after adjusting for possible confounders. Conclusion: Among patients who received inpatient palliative care consults, lower functional status was associated with a higher symptom burden. Furthermore, symptom profiles differed between patients with reduced functional status and those with preserved functional status.

Palliative Care Across the Spectrum of Heart Failure.

Persons with heart failure (HF) often suffer from poor symptom control, decreased quality of life, and poor communication with their health care providers. These needs are particularly acute in advanced HF, a leading cause of death in the United States. Palliative care, when offered alongside HF disease management, offers improved symptom control, quality of life, communication, and caregiver satisfaction as well as reduced caregiver anxiety. The dynamic nature of the clinical trajectory of HF presents distinct symptom patterns, changing functional status, and uncertainty, which requires an adaptive, dynamic model of palliative care delivery. Due to a limited specialty-trained palliative care workforce, patients and their caregivers often cannot access these benefits, especially in the community. To meet these needs, new models are required that are better informed by high-quality data, engage a range of health care providers in primary palliative care principles, and have clear triggers for specialty palliative care engagement, with specific palliative interventions tailored to patient's illness trajectory and changing needs.

Using Functional Status at the Time of Palliative Care Consult to Identify Opportunities for Earlier Referral.

Background: In order to improve early access to palliative care, strategies for monitoring referral practices in real-time are needed. Objective: To evaluate how Australia-Modified Karnofsky Performance Status (AKPS) at the time of initial palliative care consult differs between serious illnesses and could be used to identify opportunities for earlier referral. Methods: We retrospectively evaluated data from an inpatient palliative care consult registry. Serious illnesses were classified using ICD-10 codes. AKPS was assessed by palliative care clinicians during consult. Results: The AKPS distribution varied substantially between the different serious illnesses (p < 0.001). While patients with cancer and heart disease often had preserved functional status, the majority of patients with dementia, neurological, lung, liver, and renal disease were already completely bedbound at the time of initial palliative care consult. Conclusion: Measuring functional status at the time of palliative care referral could be helpful for monitoring referral practices and identifying opportunities for earlier referral.

Palliative care in heart failure guidelines: A comparison of the 2021 ESC and the 2022 AHA/ACC/HFSA guidelines on heart failure.

The role of palliative care for patients with heart failure (HF) is discussed in both most recent HF guidelines, the 2021 ESC guideline and the 2022 AHA/ACC/HFSA guideline. This review compares the definitions, concepts and specific recommendations regarding palliative care for patients with HF in these two guidelines. Both HF guidelines define palliative care as a multidisciplinary approach aimed at alleviating physical, psychological and spiritual distress of patients and caregivers. Both agree emphatically on the importance of palliative care across all stages of HF with integration early in the illness trajectory. Also, the guidelines concur that palliative care should include symptom management, communication about prognosis and life-sustaining therapies, as well as advance care planning. Despite this consensus, only the AHA/ACC/HFSA guideline gives official recommendations on the provision of palliative care. Moreover, the AHA/ACC/HFSA guideline advocates for a needs-based approach to palliative care allocation while the ESC guideline ties palliative care closely to advanced HF and end-of-life care. The ESC guideline highlights the need for regular symptom assessment and provides detailed guidance on symptom management. The AHA/ACC/HFSA guideline elaborates further on shared decision-making, caregiver and bereavement support, as well as hospice care, and distinguishes between primary palliative care (provided by all clinicians) and secondary (specialty-level) palliative care. Although there is strong agreement on the importance and components of palliative care for patients with HF, there are nuanced differences between the two HF guidelines. Most notably, only the AHA/ACC/HFSA guideline issues recommendations for the provision of palliative care.

Using Latent Class Analysis to Identify Different Clinical Profiles Among Patients With Advanced Heart Failure.

Context: Although palliative care is guideline-indicated for patients with advanced heart failure (HF), the scarcity of a specialty-trained palliative care workforce demands better identification of patients who are most burdened by the disease. Objectives: We sought to identify latent subgroups with variations regarding symptom burden, functional status, and multimorbidity in an advanced HF population. Methods: We performed a latent class analysis (LCA) of baseline data from a trial enrolling advanced HF patients. As LCA input variables, we chose indicators of HF severity, physical and psychological symptom burden, functional status, and the number of comorbidities. Results: Among 563 patients, two subgroups emerged from LCA, Class A (352 [62.5%]) and Class B (211 [37.5%]). Patients in Class A were less often classified as NYHA class III or IV (88.0% vs. 97.5%, P < 0.001), as compared to Class B patients. Class A patients had fewer symptoms, fewer comorbidities, only 25.9% had impairments in activities of daily living (ADL), and virtually none suffered from clinically significant anxiety (0.4%) or depression (0.9%). In Class B, every patient reported more than three symptoms, almost all patients (92.6%) had some impairment in ADL, and nearly a third had anxiety (30.2%) or depression (28.3%). All-cause mortality after 12 months was higher in Class B, as compared to Class A (18.5% vs. 12.5%, P = 0.047). Conclusion: Among advanced HF patients, we identified a distinct subgroup characterized by a conjunction of high symptom burden, anxiety, depression, multimorbidity, and functional status impairment, which might profit particularly from palliative care interventions.

Reduced functional capacity is associated with the proportion of impaired myocardial deformation assessed in heart failure patients by CMR.

Aims: Heart failure (HF) does not only reduce the life expectancy in patients, but their life is also often limited by HF symptoms leading to a reduced quality of life (QoL) and a diminished exercise capacity. Novel parameters in cardiac imaging, including both global and regional myocardial strain imaging, promise to contribute to better patient characterization and ultimately to better patient management. However, many of these methods are not part of clinical routine yet, their associations with clinical parameters have been poorly studied. An imaging parameters that also indicate the clinical symptom burden of HF patients would make cardiac imaging more robust toward incomplete clinical information and support the clinical decision process. Methods and results: This prospective study conducted at two centers in Germany between 2017 and 2018 enrolled stable outpatient subjects with HF [n = 56, including HF with reduced ejection fraction (HFrEF), HF with mid-range ejection fraction (HFmrEF), and HF with preserved ejection fraction (HFpEF)] and a control cohort (n = 19). Parameters assessed included measures for external myocardial function, for example, cardiac index and myocardial deformation measurements by cardiovascular magnetic resonance imaging, left ventricular global longitudinal strain (GLS), the global circumferential strain (GCS), and the regional distribution of segment deformation within the LV myocardium, as well as basic phenotypical characteristics including the Minnesota Living with Heart Failure Questionnaire (MLHFQ) and the 6-minute walk test (6MWT). If less than 80% of the LV segments are preserved in their deformation capacity the functional capacity by 6MWT (6 minutes walking distance: MyoHealth ≥ 80%: 579.8 ± 177.6 m; MyoHealth 60-<80%: 401.3 ± 121.7 m; MyoHealth 40-<60%: 456.4 ± 68.9 m; MyoHealth < 40%: 397.6 ± 125.9 m, overall p-value: 0.03) as well as the symptom burden are significantly impaired (NYHA class: MyoHealth ≥ 80%: 0.6 ± 1.1 m; MyoHealth 60-<80%: 1.7 ± 1.2 m; MyoHealth 40-<60%: 1.8 ± 0.7 m; MyoHealth < 40%: 2.4 ± 0.5 m; overall p-value < 0.01). Differences were also observed in the perceived exertion assessed by on the Borg scale (MyoHealth ≥ 80%: 8.2 ± 2.3 m; MyoHealth 60-<80%: 10.4 ± 3.2 m; MyoHealth 40-<60%: 9.8 ± 2.1 m; MyoHealth < 40%: 11.0 ± 2.9 m; overall p-value: 0.20) as well as quality of life measures (MLHFQ; MyoHealth ≥ 80%: 7.5 ± 12.4 m; MyoHealth 60-<80%: 23.4 ± 23.4 m; MyoHealth 40-<60%: 20.5 ± 21.2 m; MyoHealth < 40%: 27.4 ± 24.4 m; overall p-value: 0.15)-while these differences were not significant. Conclusion: The share of LV segments with preserved myocardial contraction promises to discriminate between symptomatic and asymptomatic subjects based on the imaging findings, even when the LV ejection fraction is preserved. This finding is promising to make imaging studies more robust toward incomplete clinical information.

Building a Cardiac Palliative Care Program: A Qualitative Study of the Experiences of Ten Program Leaders From Across the United States.

CONTEXT: Palliative care is guideline-recommended for patients with advanced heart failure (HF). However, studies on how cardiac palliative care is provided in the United States are lacking. OBJECTIVES: To study how cardiac palliative care programs provide services, and to identify challenges and facilitators they encountered in program development. METHODS: In this qualitative descriptive study, we used purposive and snowball sampling approaches to identify cardiac palliative care program leaders across the United States, administered a survey and conducted semi-structured interviews. Interview transcripts were coded and evaluated using thematic analysis. RESULTS: While cardiac palliative care programs vary in their organizational setup, they all provide comprehensive interdisciplinary palliative care services, ideally across the care continuum. They predominantly serve HF patients who are evaluated for advanced therapies or have complex needs. The challenges which cardiac palliative care programs face include reaching those cardiac patients who need palliative care the most and collaborating with cardiologists who do not see value added from palliative care for their patients. Facilitators of cardiac palliative care program development include building personal relationships with cardiology providers, proactively assessing local institution needs, and tailoring palliative care services to meet patient and provider needs. CONCLUSION: Cardiac palliative care programs vary in their organizational setup but provide similar services and face similar challenges. The challenges and facilitators we identified can inform the development of future cardiac palliative care programs.

Noninvasive evaluation of pulmonary artery stiffness in heart failure patients via cardiovascular magnetic resonance.

Heart failure (HF) presents manifestations in both cardiac and vascular abnormalities. Pulmonary hypertension (PH) is prevalent in up 50% of HF patients. While pulmonary arterial hypertension (PAH) is closely associated with pulmonary artery (PA) stiffness, the association of HF caused, post-capillary PH and PA stiffness is unknown. We aimed to assess and compare PA stiffness and blood flow hemodynamics noninvasively across HF entities and control subjects without HF using CMR. We analyzed data of a prospectively conducted study with 74 adults, including 55 patients with HF across the spectrum (20 HF with preserved ejection fraction [HFpEF], 18 HF with mildly-reduced ejection fraction [HFmrEF] and 17 HF with reduced ejection fraction [HFrEF]) as well as 19 control subjects without HF. PA stiffness was defined as reduced vascular compliance, indicated primarily by the relative area change (RAC), altered flow hemodynamics were detected by increased flow velocities, mainly by pulse wave velocity (PWV). Correlations between the variables were explored using correlation and linear regression analysis. PA stiffness was significantly increased in HF patients compared to controls (RAC 30.92 ± 8.47 vs. 50.08 ± 9.08%, p < 0.001). PA blood flow parameters were significantly altered in HF patients (PWV 3.03 ± 0.53 vs. 2.11 ± 0.48, p < 0.001). These results were consistent in all three HF groups (HFrEF, HFmrEF and HFpEF) compared to the control group. Furthermore, PA stiffness was associated with higher NT-proBNP levels and a reduced functional status. PA stiffness can be assessed non-invasively by CMR. PA stiffness is increased in HFrEF, HFmrEF and HFpEF patients when compared to control subjects.Trial registration The study was registered at the German Clinical Trials Register (DRKS, registration number: DRKS00015615).

Enhancing Palliative Care for Patients With Advanced Heart Failure Through Simple Prognostication Tools: A Comparison of the Surprise Question, the Number of Previous Heart Failure Hospitalizations, and the Seattle Heart Failure Model for Predicting 1-Year Survival.

Background: Score-based survival prediction in patients with advanced heart failure (HF) is complicated. Easy-to-use prognostication tools could inform clinical decision-making and palliative care delivery. Objective: To compare the prognostic utility of the Seattle HF model (SHFM), the surprise question (SQ), and the number of HF hospitalizations (NoH) within the last 12 months for predicting 1-year survival in patients with advanced HF. Methods: We retrospectively analyzed data from a cluster-randomized controlled trial of advanced HF patients, predominantly with reduced ejection fraction. Primary outcome was the prognostic discrimination of SHFM, SQ ("Would you be surprised if this patient were to die within 1 year?") answered by HF cardiologists, and NoH, assessed by receiver operating characteristic (ROC) curve analysis. Optimal cut-offs were calculated using Youden's index (SHFM: <86% predicted 1-year survival; NoH ≥ 2). Results: Of 535 subjects, 82 (15.3%) had died after 1-year of follow-up. SHFM, SQ, and NoH yielded a similar area under the ROC curve [SHFM: 0.65 (0.60-0.71 95% CI); SQ: 0.58 (0.54-0.63 95% CI); NoH: 0.56 (0.50-0.62 95% CI)] and similar sensitivity [SHFM: 0.76 (0.65-0.84 95% CI); SQ: 0.84 (0.74-0.91 95% CI); NoH: 0.56 (0.45-0.67 95% CI)]. As compared to SHFM, SQ had lower specificity [SQ: 0.33 (0.28-0.37 95% CI) vs. SHFM: 0.55 (0.50-0.60 95% CI)] while NoH had similar specificity [0.56 (0.51-0.61 95% CI)]. SQ combined with NoH showed significantly higher specificity [0.68 (0.64-0.73 95% CI)]. Conclusion: SQ and NoH yielded comparable utility to SHFM for 1-year survival prediction among advanced HF patients, are easy-to-use and could inform bedside decision-making.

CMR detects decreased myocardial deformation in asymptomatic patients at risk for heart failure.

Aims: The main management strategy of heart failure with preserved ejection fraction (HFpEF) is prevention since HFpEF is associated with many cardiovascular (CV) risk factors, especially since HFpEF is linked to a high risk for both mortality and recurrent heart failure (HF) hospitalizations. Therefore, there is a need for new tools to identify patients with a high risk profile early. Regional strain assessment by CMR seems to be superior in describing deformation impairment in HF. The MyoHealth score is a promising tool to identify cardiac changes early. Methods and results: Heart failure patients irrespective of LVEF and asymptomatic controls were recruited, and CMR based measures were obtained. For this analysis the asymptomatic control group (n = 19) was divided into asymptomatic subjects without CV co-morbidities or evidence of cardiac abnormalities and (n = 12) and asymptomatic subjects with CV co-morbidities or evidence of cardiac abnormalities (n = 7) as well as patients with HFpEF (n = 19). We performed CMR scans at rest and during a stress test using isometric handgrip exercise (HG). Assessing the MyoHealth score at rest revealed preserved regional strain in 85 ± 9% of LV segments in controls, 73 ± 11% in at Risk subjects and 73 ± 8% in HFpEF patients. During stress the MyoHealth score was 84 ± 7% in controls, 83 ± 7 in at risk subjects and 74 ± 11 in HFpEF patients. Conclusion: In summary, we show for the first time that asymptomatic subjects with increased CV risk present with HFpEF like impaired myocardial deformation at rest, while they show results like controls under HG stress. The potential of preventive treatment in this group of patients merits further investigation in future.

Myocardial deformation assessed among heart failure entities by cardiovascular magnetic resonance imaging.

AIMS: Although heart failure (HF) is a leading cause for hospitalization and mortality, normalized and comparable non-invasive assessment of haemodynamics and myocardial action remains limited. Moreover, myocardial deformation has not been compared between the guideline-defined HF entities. The distribution of affected and impaired segments within the contracting left ventricular (LV) myocardium have also not been compared. Therefore, we assessed myocardial function impairment by strain in patients with HF and control subjects by magnetic resonance imaging after clinically phenotyping these patients. METHODS AND RESULTS: This prospective study conducted at two centres in Germany between 2017 and 2018 enrolled stable outpatient subjects with HF [n = 56, including HF with reduced ejection fraction (HFrEF), HF with mid-range ejection fraction (HFmrEF), and HF with preserved ejection fraction (HFpEF)] and a control cohort (n = 12). Parameters assessed included measures for external myocardial function, for example, cardiac index and myocardial deformation measurements by cardiovascular magnetic resonance imaging, left ventricular global longitudinal strain (GLS), the global circumferential strain (GCS) and the regional distribution of segment deformation within the LV myocardium, as well as basic phenotypical characteristics. Comparison of the cardiac indices at rest showed no differences neither between the HF groups nor between the control group and HF patients (one-way ANOVA P = 0.70). The analysis of the strain data revealed differences between all groups in both LV GLS (One-way ANOVA: P < 0.01. Controls vs. HFpEF: -20.48 ± 1.62 vs. -19.27 ± 1.25. HFpEF vs. HFmrEF: -19.27 ± 1.25 vs. -15.72 ± 2.76. HFmrEF vs. HFrEF: -15.72 ± 2.76 vs. -11.51 ± 3.97.) and LV GCS (One-way ANOVA: P < 0.01. Controls vs. HFpEF: -19.74 ± 2.18 vs. -17.47 ± 2.10. HFpEF vs. HFmrEF: -17.47 ± 2.10 vs. -12.78 ± 3.47. HFrEF: -11.41 ± 3.27). Comparing the segment deformation distribution patterns highlighted the discriminating effect between the groups was much more prominent between the groups (one-way ANOVA P < 0.01) when compared by a score combining regional effects and a global view on the LV. Further analyses of the patterns among the segments affected showed that while the LVEF is preserved in HFpEF, the segments impaired in their contractility are located in the ventricular septum. The worse the LVEF is, the more segments are affected, but the septum remains an outstanding location with the most severe contractility impairment throughout the HF entities. CONCLUSIONS: While cardiac index at rest did not differ significantly between controls and stable HF patients suffering from HFrEF, HFmrEF, or HFpEF, the groups did differ significantly in LV GLS and LV GCS values. Regional strain analysis revealed that the LV septum is the location affected most, with reduced values already visible in HFpEF and further reductions in HFmrEF and HFrEF.

Device profile of the Resolute Onyx Zotarolimus eluting coronary stent system for the treatment of coronary artery disease: overview of its safety and efficacy.

Introduction: The increasing complexity of patients undergoing percutaneous coronary intervention (PCI) regarding both coronary anatomy and comorbidities requires dedicated devices. The Resolute Onyx (R-Onyx, Medtronic, CA, USA) stent is a novel durable polymer zotarolimus-eluting stent (ZES) promising better deliverability, increased radiopacity and lower thrombogenicity.Areas covered: In this review, we discuss device features, preclinical evidence, and clinical studies including patients treated with R-Onyx. The BIONYX and Onyx ONE studies were two major landmark trials demonstrating non-inferiority of R-Onyx as compared to other latest generation devices. We also elaborate on alternative innovations in drug-eluting stent (DES) technology and how R-Onyx fits into this field.Expert opinion: R-Onyx is designed to address the challenges of contemporary PCI, but evidence on its clinical performance is largely derived from studies on older generation devices from the ZES family. Nonetheless, all clinical studies on R-Onyx consistently show excellent outcomes, with particularly low rates of stent thrombosis, making it a promising candidate for short dual antiplatelet regimens. In addition, R-Onyx is available with a wide range of stent diameters allowing accurate sizing for both very small and very large coronary vessels.

Multilayer myocardial strain improves the diagnosis of heart failure with preserved ejection fraction.

AIMS: The diagnostic and treatment of patients with heart failure with preserved ejection fraction (HFpEF) are both hampered by an incomplete understanding of the pathophysiology of the disease. Novel imaging tools to adequately identify these patients from individuals with a normal cardiac function and respectively patients with HF with reduced EF are warranted. Computing multilayer myocardial strain with feature tracking is a fast and accurate method to assess cardiac deformation. Our purpose was to assess the HFpEF diagnostic ability of multilayer strain parameters and compare their sensitivity and specificity with other established parameters. METHODS AND RESULTS: We included 20 patients with a diagnosis of HFpEF and, respectively, 20 matched controls. We assessed using feature-tracking cardiac magnetic resonance longitudinal and circumferential myocardial strain at three distinct layers of the myocardium: subendocardial (Endo-), mid-myocardial (Myo-), and subepicardial (Epi-). Comparatively, we additionally assessed various others clinical, imaging, and biochemical parameters with a putative role in HFpEF diagnostic: left ventricular end-diastolic volume (LVEDV), left ventricular mass (LVM), interventricular septum (IVS) wall thickness and free wall thickness, left atrial volume and strain, septal and lateral mitral annular early diastolic velocity (e`), E/e´ ratio, and plasma levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP). Global longitudinal strain (GLS) is significantly impaired at Endo (-20.8 ± 4.0 vs. -23.2 ± 3.4, P = 0.046), Myo- (-18.0 ± 3.0 vs. -21.0 ± 2.5, P = 0.002), and Epi- (-12.2 ± 2.0 vs. -16.2 ± 2.5, P < 0.001) levels. Compared with any other imaging parameter, an Epi-GLS lower than 13% shows the highest ability to detect patients with HFpEF [area under the curve (AUC) = 0.90 (0.81-1), P < 0.001] and in tandem with NT-proBNP can diagnose with maximal sensibility (93%) and specificity (100%), patients with HFpEF from normal, composed variable [AUC = 0.98 (0.95-1), P < 0.001]. In a logistic regression model, a composite predictive variable taking into account both GLS Epi and NT-proBNP values in each individual subject reached a sensitivity of 89% and a specificity of 100% with an AUC of 0.98 (0.95-1), P < 0.001, to detect HFpEF. CONCLUSIONS: Epi-GLS is a promising new imaging parameter to be considered in the clinical assessment of HFpEF patients. Given its excellent specificity, in tandem with a highly sensitive parameter such as NT-proBNP, Epi-GLS holds the potential to greatly improve the current diagnostic algorithms.

Syncopes and clinical outcome in heart failure: results from prospective clinical study data in Germany.

AIMS: Whereas syncopal episodes are a frequent complication of cardiovascular disorders, including heart failure (HF), little is known whether syncopes impact the prognosis of patients with HF. We aimed to assess the impact of a history of syncope (HoS) on overall and hospitalization-free survival of these patients. METHODS AND RESULTS: We pooled the data of prospective, nationwide, multicentre studies conducted within the framework of the German Competence Network for Heart Failure including 11 335 subjects. Excluding studies with follow-up periods <10 years, we assessed 5318 subjects. We excluded a study focusing on cardiac changes in patients with an HIV infection because of possible confounding factors and 849 patients due to either missing key parameters or missing follow-up data, resulting in 3594 eligible subjects, including 2130 patients with HF [1564 patients with heart failure with reduced ejection fraction (HFrEF), 314 patients with heart failure with mid-range ejection fraction, and 252 patients with heart failure with preserved ejection fraction (HFpEF)] and 1464 subjects without HF considered as controls. HoS was more frequent in the overall cohort of patients with HF compared with controls (P < 0.001)-mainly driven by the HFpEF subgroup (HFpEF vs. controls: 25.0% vs. 12.8%, P < 0.001). Of all the subjects, 14.6% reported a HoS. Patients with HFrEF in our pooled cohort showed more often syncopes than subjects without HF (15.0% vs. 12.8%, P = 0.082). Subjects with HoS showed worse overall survival [42.4% vs. 37.9%, hazard ratio (HR) = 1.21, 99% confidence interval (0.99, 1.46), P = 0.04] and less days alive out of hospital [HR = 1.39, 99% confidence interval (1.18, 1.64), P < 0.001] compared with all subjects without HoS. Patients with HFrEF with HoS died earlier [30.3% vs. 41.6%, HR = 1.40, 99% confidence interval (1.12, 1.74), P < 0.001] and lived fewer days out of hospital than those without HoS. We could not find these changes in mortality and hospital-free survival in the heart failure with mid-range ejection fraction and HFpEF cohorts. HoS represented a clinically high-risk profile within the HFrEF group-combining different risk factors. Further analyses showed that among patients with HFrEF with HoS, known cardiovascular risk factors (e.g. age, male sex, diabetes mellitus, and anaemia) were more prevalent. These constellations of the risk factors explained the effect of HoS in a multivariable Cox regression models. CONCLUSIONS: In a large cohort of patients with HF, HoS was found to be a clinically and easily accessible predictor of both overall and hospitalization-free survival in patients with HFrEF and should thus routinely be assessed.
