Efficacy and safety of CDR132L in patients with reduced left ventricular ejection fraction after myocardial infarction: Rationale and design of the HF-REVERT trial.

AIM: Inhibition of microRNA (miR)-132 effectively prevents and reverses adverse cardiac remodelling, making it an attractive heart failure (HF) target. CDR132L, a synthetic antisense oligonucleotide selectively blocking pathologically elevated miR-132, demonstrated beneficial effects on left ventricular (LV) structure and function in relevant preclinical models, and was safe and well tolerated in a Phase 1b study in stable chronic HF patients. Patients with acute myocardial infarction (MI) and subsequent LV dysfunction and remodelling have limited therapeutic options, and may profit from early CDR132L treatment. METHODS: The HF-REVERT (Phase 2, multicenter, randomized, parallel, 3-arm, placebo-controlled Study to Assess Efficacy and Safety of CDR132L in Patients with Reduced Left Ventricular Ejection Fraction after Myocardial Infarction) evaluates the efficacy and safety of CDR132L in HF patients post-acute MI (n = 280), comparing the effect of 5 and 10 mg/kg CDR132L, administered as three single intravenous doses 28 days apart, in addition to standard of care. Key inclusion criteria are the diagnosis of acute MI, the development of systolic dysfunction (LV ejection fraction ≤45%) and elevated N-terminal pro-B-type natriuretic peptide. The study consists of a 6-month double-blinded treatment period with the primary endpoint LV end-systolic volume index and relevant secondary endpoints, followed by a 6-month open-label observation period. CONCLUSION: The HF-REVERT trial may underpin the concept of miR-132 inhibition to prevent or reverse cardiac remodelling in post-MI HF. The results will inform the design of subsequent outcome trials to test CDR132L in HF.

Changes in circulating ApoJ-Glyc levels in patients with suspected acute coronary syndrome: The EDICA trial.

BACKGROUND: Myocardial ischemia induces intracellular accumulation of non-glycosylated apolipoprotein J that results in a reduction of circulating glycosylated ApoJ (ApoJ-Glyc). The latter has been suggested to be a marker of transient myocardial ischemia. OBJECTIVE: This proof-of-concept clinical study aimed to assess whether changes in circulating ApoJ-Glyc could detect myocardial ischemia in patients attending the emergency department (ED) with chest pain suggestive of acute coronary syndrome (ACS). METHODS: In suspected ACS patients, EDICA (Early Detection of Myocardial Ischemia in Suspected Acute Coronary Syndromes by ApoJ-Glyc a Novel Pathologically based Ischemia Biomarker), a multicentre, international, cohort study assessed changes in 2 glycosylated variants of ApoJ-Glyc, (ApoJ-GlycA2 and ApoJ-GlycA6), in serum samples obtained at ED admission (0 h), and 1 h and 3 h thereafter, blinded to the clinical diagnosis (i.e. STEMI, NSTEMI, unstable angina, non-ischemic). RESULTS: 404 patients were recruited; 291 were given a clinical diagnosis of "non-ischemic" chest pain and 113 were considered to have had an ischemic event. ApoJ-GlycA6 was lower on admission in ischemic compared with "non-ischemic" patients (66 [46-90] vs. 73 [56-95] µg/ml; P = 0.04). 74% of unstable angina patients (all with undetectable hs-Tn), had ischemic changes in ApoJ-Glyc at 0 h and 89% at 1 h. Initially low ApoJ-Glyc levels in 62 patients requiring coronary revascularization increased significantly after successful percutaneous intervention. CONCLUSIONS: Circulating ApoJ-Glyc concentrations decrease early in ED patients with myocardial ischemia compared with "non-ischemic" patients, even in the absence of troponin elevations. ApoJ-Glyc may be a useful marker of myocardial ischemia in the ED setting.

Aspergillus endocarditis in the recent years, report of cases of a multicentric national cohort and literature review.

OBJECTIVES: (1) To describe the incidence, clinical characteristics, treatment and outcome of Aspergillus Endocarditis (AE) in a nationwide multicentric cohort (GAMES). (2) To compare the AE cases of the GAMES cohort, with the AE cases reported in the literature since 2010. (3) To identify variables related to mortality. METHODS: We recruited 10 AE cases included in the GAMES cohort (January 2008-December 2018) and 51 cases from the literature published from January 2010 to July 2019. RESULTS: 4528 patients with infectious endocarditis (IE) were included in the GAMES cohort, of them 10 (0.2%) were AE. After comparing our 10 cases with the 51 of the literature, no differences were found. Analysing the 61 AE cases together, 55.7% were male, median age 45 years. Their main underlying conditions were as follows: prosthetic valve surgery (34.4%) and solid organ transplant (SOT) (19.7%). Mainly affecting mitral (36.1%) and aortic valve (29.5%). Main isolated species were as follows: Aspergillus fumigatus (47.5%) and Aspergillus flavus (24.6%). Embolisms occurred in 54%. Patients were treated with antifungals (90.2%), heart surgery (85.2%) or both (78.7%). Overall, 52.5% died. A greater mortality was observed in immunosuppressed patients (59.4% vs. 24.1%, OR = 4.09, 95%CI = 1.26-13.19, p = .02), and lower mortality was associated with undergoing cardiac surgery plus azole therapy (28.1% vs. 65.5%, OR = 0.22, 95%CI = 0.07-0.72, p = .01). CONCLUSIONS: AE accounts for 0.2% of all IE episodes of a national multicentric cohort, mainly affecting patients with previous valvular surgery or SOT recipients. Mortality remains high especially in immunosuppressed hosts and azole-based treatment combined with surgical resection are related to a better outcome.

Use of edoxaban in clinical practice: Comparison of data from the Spanish population in the ETNA-AF-Europe registry.

Aim: To ascertain the clinical profile and management of edoxaban in clinical practice. Materials & methods: Prospective, noninterventional postauthorization study of nonselected patients with atrial fibrillation treated with edoxaban from 12 European countries. Patients' baseline characteristics are presented. Results: A total of 13,638 patients (73.6 ± 9.5 years; 76.6/23.4% edoxaban 60/30 mg; CHA2DS2-VASc 3.1; 838 [6.1%] from Spain) were included. In Spain, the percentage of very elderly and fragile patients was greater and the risk of thromboembolism (CHA2DS2-VASc ≥2, 98.0 vs 87.3%; p < 0.001) and bleeding (HAS-BLED, 3.2 vs 2.7; p < 0.001) was greater in patients treated with edoxaban 30 mg. The proportion of patients taking edoxaban 30 mg was similar than in ENGAGE AF-TIMI 48. Conclusion: In Spain, patients treated with edoxaban were older and fragile.

Long term clinical outcomes in survivors after out-of-hospital cardiac arrest.

INTRODUCTION AND OBJECTIVES: Information regarding long-term outcomes in patients surviving out-of-hospital cardiac arrest (OHCA) is scarce. Our aim was to study the long-term clinical outcomes of a large cohort of OHCA patients surviving until hospital discharge and to identify predictors of mortality and cardiovascular events. METHODS: Consecutive OHCA patients admitted in the Acute Cardiac Care Unit who survived at least until hospital discharge between 2007 and 2019 were included. All received therapeutic hypothermia according to the local protocol. Pre- and intra-hospital clinical and analytical variables were analyzed, as well as the clinically relevant events during follow-up. RESULTS: A total of 201 patients were included, with a mean age of 57.6 ± 14.2 years, 168 (83.6%) were male. Thirty-six (17.9%) died during a median follow-up of 40.3 months (18.9-69.1), the most frequent causes of death being cardiovascular and neurological, followed by cancer. We calculated a predictive model for mortality during follow-up using Cox regression that included the following variables: poor neurological outcome [HR 3.503 (1.578-7.777)], non-shockable rhythm [HR 2.926 (1.390-6.163)], time to onset of CPR [HR 1.063 (0.997-1.134)], older age [1.036 (1.008-1.064)) and worse ejection fraction at discharge [1.033 (1.009-1.058)]. CONCLUSIONS: Even though few patients experience recurrent cardiac arrest events, survivors after OHCA face high morbidity and mortality during long-term follow-up. Therefore, they may benefit from multidisciplinary teams providing an integral management and ensuring continuity of care.

Etiología de la insuficiencia renal en pacientes con endocarditis infecciosa. Papel de los antibióticos / Aetiology of renal failure in patients with infective endocarditis. The role of antibiotics

Fundamento y objetivos: La toxicidad renal de ciertos antibióticos (AB) es conocida. El objetivo de nuestro trabajo es conocer el posible efecto de los tratamientos AB en el desarrollo de insuficiencia renal (IR) en pacientes con endocarditis infecciosa (EI). Material y método: Recogida en un registro nacional multicéntrico de los datos referentes a la función renal, tanto previa como su deterioro si existiese, durante el tratamiento de las EI y relacionarlo con los posibles factores causantes, entre ellos los AB. Resultados: Entre 2008 y 2012 se han analizado 1.853 episodios de EI remitidos desde 26 centros españoles. De ellos, un 21,6% presentaban una alteración previa de la función renal. Desarrollaron IR de novo o un empeoramiento de la función renal previa un 38,7% de los casos. En aquellos pacientes que presentaban IR previa, el deterioro fue más frecuente (64 frente a 31,7%; p<0,001). Globalmente los pacientes con IR tenían más edad (70,6 frente a 67 años; p<0,01) y comorbilidades (índice de Charlson 5 frente a 4; p<0,01), y la EI era por Staphylococcus aureus (32,1 frente a 16,5%; p<0,01). El uso de AB potencialmente nefrotóxicos solo se asoció a IR en el grupo de pacientes sin IR previa (aminoglucósidos: OR=1,47 [IC 95% 1,096-1,988], p=0,010; aminoglucósidos-vancomicina: OR=1,49 [IC 95% 1,069-2,09], p=0,019]). Conclusiones: En pacientes sin IR previa, los AB nefrotóxicos se asocian a un deterioro de la función renal. En pacientes con IR previa al episodio de EI, el deterioro de renal fue más frecuente, pero parece estar más relacionado con la gravedad de la infección (AU)

Background and objectives: The possible renal toxicity of certain antibiotics (AB) is well known. The objective of our work is to know the possible effect of AB treatments in the development of renal failure (RF) in patients with infective endocarditis (IE). Material and method: Collection from a national multi-centre registry of collection on renal function, both prior and its impairment, if any, during the treatment of IE and in relation to possible causative factors, including the use of AB. Results: Between 2008 and 2012, 1,853 episodes of IE reported from 26 Spanish centres were analysed. Of these, 21.6% had prior RF. They developed new RF or impairment of renal function in 38.7% of the cases. In patients with prior RF, impairment was more frequent (64 vs. 31.7%, P<.001). Overall, patients with RF were older (70.6 vs. 67 years, P<.01), had more comorbidities (Charlson index 5 vs. 4, P<.01), and IE by Staphylococcus aureus (32.1 vs. 16.5%, P<.01). Potentially nephrotoxic AB use was only associated with RF in patients without prior RF (aminoglycosides: OR=1.47 [95% CI 1.096-1.988], P=.010; aminoglycosides with vancomycin: OR=1.49 [95% CI 1.069-2.09], P=.019). Conclusions: In patients without prior RF, the use of nephrotoxic AB is associated with impairment of renal function. In patients with RF prior to the IE episode, impairment of renal function was more frequent but appears to be more related to the severity of infection (AU)
