RESUMEN
INTRODUCTION: Safety and early clinical benefit make sodium-glucose cotransporter-2 inhibitor (SGLT2-i) therapy suitable for in-hospital initiation in patients with heart failure and reduced ejection fraction (HFrEF). Despite randomized controlled trials and guideline recommendations, they are underused, and clinical inertia may play a role. OBJECTIVES PRIMARY: To assess the impact of initiating SGLT-2i at discharge on 90-day prescription rates in patients with HFrEF during hospitalization for acute heart failure (AHF). Secondary: To evaluate the presence of independent factors associated with prescription, and to explore clinical outcomes at 90 days. METHODS: Retrospective analysis of a consecutive prospective single-center cohort. Adult patients hospitalized between January 2021 and September 2022 with a primary diagnosis of AHF and left ventricular ejection fraction (LVEF) <40% were included. The primary outcome was SGLT2-i prescription rate at 90 days, and the exploratory secondary endpoints was the composite of hospitalization or urgent visit for AHF or all-cause mortality at 90 days. RESULTS: 237 patients were included. Mean age was 76±11 years, and mean LVEF was 29±7%. In patients without contraindications, SGLT2 inhibitors (SGLT2-i) were prescribed during hospitalization in 52.3%. At 90 days, the SGLT2-i prescription rate was 94.2% in those with in-hospital initiation and 14.4% in those without. (p<0.001). Independent factor associated with inpatient prescription was lower LVEF, 0.83 (95% CI: 0.77-0.89) for each point. Patients with in-hospital SGLT2-i initiation showed a lower rate of the combined endpoint of all-cause death, HF rehospitalization, or unplanned HF visit at 90 days (44.4% versus 23.9%, p=0.005). CONCLUSIONS: In-hospital initiation of SGLT-2-i was associated with significantly higher prescription rates and lower prevalence in the secondary combined endpoint at 90 days. This study reflects the presence of medical inertia, particularly in patients with higher LVEF, and highlights the hospitalization period as an optimal time to start SGLT2-i.
RESUMEN
BACKGROUND: Effective treatment of non-ST-segment elevation acute coronary syndromes (NSTEACS) requires careful assessment of both ischaemic and bleeding risks. We aimed to analyse risk distribution and evaluate antiplatelet prescription behaviours in real-life settings. METHODS: Data from 1100 NSTEACS patients in Buenos Aires, Argentina, from the Buenos Aires I Registry, with a 15-month follow-up, were analysed. In-hospital and 6-month GRACE scores, CRUSADE, and Precise DAPT scores were calculated. RESULTS: The mean age was 65.4 ± 11.5 years with a majority being male (77.2%). In-hospital mortality was 2.7%, primarily due to cardiovascular causes (1.8%). Bleeding events occurred in 20.9% of patients, with 4.9% classified as ≥ BARC 3. Predominance of low bleeding (71.3%) and ischaemic (55.8%) risks on admission was observed. At 6 months, the low-risk Precise category (70.9%) and GRACE (44.1%) categories prevailed. Linear correlation analysis showed a moderately positive correlation (r = 0.61, p < .05) between ischaemic-haemorrhagic risks. Regarding the prescription of antiplatelet agents, in the low ischaemic-haemorrhagic risk group, there was a predominance of aspirin + clopidogrel (41.2%) over other high-potency antiplatelet regimens (aspirin + ticagrelor or prasugrel). In the low ischaemic and high haemorrhagic risk group, aspirin and clopidogrel were also predominant (58%). CONCLUSIONS: Our analysis underscores the significant relationship between ischaemic and haemorrhagic risks during NSTEACS hospitalisation. Despite the majority of patients falling into the low-intermediate risk category, the prescription of P2Y12 inhibitors in real-life settings does not consistently align with these risks.
RESUMEN
Objectives: To identify predictors of coronary artery bypass graft surgery (CABG) requirement as a revascularization method in in real-world non-ST-segment elevation acute coronary syndrome (NSTE-ACS) patients. Materials and methods: . An individual pre-specified analysis of patients with NSTE-ACS was performed from two prospective Argentine registries between 2017 and 2022. We analyzed the difference in baseline characteristics between patients who required CABG and those who did not require this intervention. Then, a logistic regression analysis was performed to determine independent predictors in patients who received CABG as a method of revascularization. Results: A total of 1848 patients with a median age of 54.8 (interquartile range [IQR]: 53.7-56) years and an ejection fraction of 42.1% (IQR: 41.2-43.1) were included. A total of 233 patients required CABG (12.6%). Baseline characteristics between the two groups were similar, except in patients requiring CABG, who were younger (51.5 vs. 55.7 years; p=0.010), more frequently diabetic (38.2% vs. 25.7%; p=0.001) and male (90.1% vs. 73.7%; p=0.001). In addition, they had, to a lesser extent, previous cardiac surgery (2.1% vs. 11.2%; p=0.011). After multivariable analysis, the following were independently associated with CABG: age (Odds Ratio [OR]: 0.99, 95% confidence interval [CI]: 0.98-0.99; p=0.008), male sex (OR: 3.08, 95% CI: 1.87-5.1; p=0.001), history of previous CABG (OR: 0.14, 95% CI: 0.05-0.30; p=0.001) and diabetes (OR: 1.84, 95% CI: 1.31- 2.57; p=0.001). Conclusions: In this analysis of two NSTEACS registries, younger age, male sex, a diagnosis of diabetes and the absence of previous surgery were independent predictors of the requirement for inpatient CABG.
RESUMEN
BACKGROUND: Hypertrophic cardiomyopathy is a condition associated with an increased risk of sudden death compared to the general population. Extended septal myectomy surgery has been suggested to impact the reduction of sudden death events according to various publications. The aim of this study was to assess changes in the prevalence of sudden death predictors in a population of patients undergoing extended septal myectomy surgery. METHODS: Ninety-four consecutive patients underwent extended septal myectomy surgery due to symptomatic hypertrophic cardiomyopathy. Risk factors for sudden death, as defined by the American Heart Association and the European Society of Cardiology, were evaluated before and three months after surgery. RESULTS: The mean age of the population was 57 ± 13 years. A significant reduction was observed in the maximum septal thickness from 21.3 to 14 mm (p<0.001), along with a decrease in the anteroposterior diameter of the left atrium from 51 to 47 mm (p=0.021). Resting intraventricular gradients decreased from 49.2 to 6.4 mmHg (p<0.001), and Valsalva-induced gradients decreased from 93.9 to 8.7 mmHg (p<0.001). Non-sustained ventricular tachycardia decreased from 6% to 2% (p<0.001), and atrial fibrillation decreased from 30% to 15% (p<0.001). Ischemic behavior during exercise stress echo decreased from 6% to 0%, and the European Society of Cardiology sudden death risk score reduced from 3.32 to 1.44 (p<0.001). CONCLUSIONS: In this cohort of hypertrophic cardiomyopathy patients, extended septal myectomy surgery was associated with a reduction in the number and magnitude of sudden death predictors, potentially explaining the reduced mortality reported in the literature.

BACKGROUND: Nowadays, percutaneous procedures are expanding in use, and this comes with complications associated with the procedure itself. Cardiac tamponade is rare but may be life threatening since it can involve hemodynamic instability. It is known that after pleural effusion during a percutaneous procedure, pericardiocentesis should be used as drainage of the cavity. However, that does not achieve hemostasis in some cases, and in those patients who are hemodynamically unstable, a sealing agent to promote hemostasis might be useful, like thrombin. CASE PRESENTATION: We present a case report of 89-year-old patient with history of melanoma undergoing treatment with pembrolizumab, who attended the emergency department referring chest pain (intensity 5/10) and palpitations that have lasted hours. He had TnTUs 554/566 ng/L and an echocardiogram that showed dilated right chambers, hypertrophy and global hypokinesia of the left ventricle, increased filling pressures of the left ventricle and pulmonary hypertension. Myocarditis associated with pembrolizumab was suspected, so high dose steroids were initiated and endomyocardial biopsy was conducted, resulting in iatrogenic cardiac tamponade. To determine the etiology of the suspected myocarditis, an endomyocardial biopsy was performed. Unfortunately, an intraprocedural complication arose: pleural effusion resulting in iatrogenic cardiac tamponade, leading to hemodynamic instability. It required immediate pericardial drainage via subxiphoid puncture, obtaining a 550 mL hematic debit. Clinical manifestations raised suspicion of tamponade, prompting a bedside echocardiogram for a definitive diagnosis. Despite these efforts, the patient remained hemodynamically unstable, and due to the elevated surgical risk, intrapericardial thrombin was employed to achieve successful hemostasis. CONCLUSIONS: Cardiac tamponade is a life-threatening condition that can sometimes be induced iatrogenically, resulting from percutaneous interventions. Despite limited evidence regarding this therapeutic strategy, in patients experiencing iatrogenic cardiac tamponade with hemodynamic instability and high surgical risk, the administration of intra-pericardial thrombin could be contemplated.
RESUMEN
BACKGROUND: In patients presenting with acute coronary syndrome (ACS) current clinical practice guidelines recommend coronary angiography for its study. This study aims to describe the role of coronary tomography (CT) in non-ST-segment elevation acute coronary syndromes (NSTE-ACS). RESULTS: Patients over 18 years with a diagnosis of NSTE-ACS who did not meet high-risk criteria and consulted the emergency department of our institution were included. A total of 410 patients were included, in 7% of them, the study was not continued due to an elevated calcium score (>400 AU). 27% had no coronary lesions, 38% had non-obstructive coronary disease (plaques <50%), 27% had plaques over 50%, and 8% were not assessable. Of the total patients, 39% underwent coronary angiography, and 22% required percutaneous angioplasty. CONCLUSIONS: Performing CT in low and moderate-risk NSTE-ACS patients was feasible, avoiding invasive studies in a significant number of patients and providing extensive anatomical information.

INTRODUCTION: Transthyretin amyloid cardiomyopathy (ATTR-CM) is an underdiagnosed cause of AHF that benefits from a specific approach. The aim was to determine the prevalence of ATTR-CM among patients hospitalized for AHF. METHODS: A prospective study was conducted on consecutive patients aged 60 or older admitted for acute AHF without cardiogenic shock. RESULTS: The study included 103 patients, a total of 16 patients (15.5 %) were compatible with ATTR-CM. The ATTR-CM group showed a higher septal wall thickness (18.1 mm vs. 11.8 mm; P = 0.001), lower systolic excursion of the tricuspid annular plane (15 mm vs. 18.3 mm, P = 0.014), and S wave of the right ventricle (8 cm/s vs. 9.2 cm/s P=0.032). CONCLUSION: ATTR-CM is an underdiagnosed condition, there are some variables associated with its diagnosis. The coexistence with other comorbidities causing AHF, highlights the importance of considering screening for this cardiomyopathy in adults hospitalized for AHF.

RESUMEN La decisión sobre la mejor estrategia de revascularización para los pacientes con enfermedad de múltiples vasos se ha tornado una tarea compleja a medida que la angioplastia coronaria ha mejorado sus resultados. En la siguiente revisión nos propusimos evaluar las variables que en nuestra experiencia definen el beneficio de una técnica sobre la otra, entendiendo que de esta manera la decisión del médico tratante se hace más sencilla y objetiva. Por otro lado, y festejando el saludable protagonismo que se le da al paciente, creemos que esta evaluación permite ofrecer argumentos sólidos para ayudarlo en la toma de la decisión.
ABSTRACT The decision on the best revascularization strategy for patients with multivessel disease has become a complex task as coronary angioplasty has improved its results. In the following review, we set out to evaluate the variables that, in our experience, define the benefit of one technique over the other, understanding that in this way the treating physician's decision will become simpler and more objective. On the other hand, and celebrating the healthy prominence given to patients, we believe that this evaluation allows solid arguments to help them in decision making.

BACKGROUND AND OBJECTIVE: Olfactory and taste dysfunction (OD, TD) have been considered symptoms of SARS-CoV-2 infection. However, its presence in certain populations, especially those with mild clinical symptoms, has not been clarified. The objective was to estimate the frequency of OD and TD, and its predictive validity in patients detected in Primary Care. PATIENTS AND METHODS: A cross-sectional study was carried out in the Spanish National Health System. An epidemiological survey was administered to patients who were requested the PCR test for SARS-CoV-2. Odds ratio (OR) were estimated to measure the magnitude of the association between OD and TD and the existence of SARS-CoV-2 infection. The sensitivity, specificity, and positive and negative predictive values (PPV, NPV) of these symptoms in SARS-CoV-2 infection were calculated. RESULTS: Of 1038 patients screened, 20.1% had SARS-CoV-2 infection. OD and DG were present in 64.4% (95% CI 56.0-72.1) and 56.2% (95% CI 47.9-64.2) of the subjects with infection, respectively. The OR for OD was 12.2 (95% CI 8.26-18.06) and for TD was 7.95 (95% CI 5.48-11.53). TD presented a sensitivity of 41.1% (95% CI 34.4-46.1), a specificity of 91.9% (95% CI 89.8-93.7), a PPV of 56.2% (95% CI48.0-64.2) and a NPV of 86.1% (95% CI 83.6-88.3), while the OD showed a sensitivity of 45.0% (95% CI 37.6-51.5), a specificity of 93.7% (95% CI 91.8-95.0), a PPV of 64.4% (95% CI 56.0-72.1) and a NPV of 87.1% (95% CI 84.7-89.2). CONCLUSIONS: More than half of the subjects with SARS-CoV-2 infection have OD or TD. The presence of OD or TD could be of diagnostic utility due to its ability to predict infection in more than half of the cases.
ANTECEDENTES Y OBJETIVO: La disfunción olfatoria (DO) y gustativa (DG) han demostrado ser síntomas de la infección por SARS-CoV-2. Sin embargo, su presencia en determinadas poblaciones, sobre todo en aquellas con cuadros clínicos leves, aún debe aclararse. El objetivo fue estimar la frecuencia de DO y DG, y su validez predictiva en pacientes detectados en Atención Primaria. PACIENTES Y MÉTODOS: Se realizó un estudio transversal en el Sistema Nacional de Salud español. Se administró una encuesta epidemiológica dirigida a pacientes a los que se les solicitó la prueba PCR para SARS-CoV-2. Se estimaron las odds ratio (OR) para medir la magnitud de la asociación entre la DO y DG y la existencia de infección por SARS-CoV-2. Se calculó la sensibilidad, la especificidad y los valores predictivos positivos (VPP) y negativos (VPN) de estos síntomas en la infección por SARS-CoV-2. RESULTADOS: Se captaron 1.038 pacientes, de los cuales el 20,1% presentaban infección por SARS-CoV-2. Las DO y DG estuvieron presentes en el 64,4% (IC 95% 56,072,1) y el 56,2% (IC 95% 47,964,2) de los sujetos con infección, respectivamente. La OR para la DO fue de 12,2 (IC 95% 8,26−18,06) y para la DG de 7,95 (IC 95% 5,48−11.53). La DG presentó una sensibilidad del 41,1% (IC 95% 34,446,1), una especificidad del 91,9% (IC 95% 89,893,7), un VPP del 56,2% (IC 95% 48,064,2) y un VPN de 86,1% (IC 95% 83,688,3), mientras que la DO mostró una sensibilidad del 45,0% (IC 95% 37,651,5), una especificidad del 93,7% (IC 95% 91,895,0), un VPP del 64,4% (IC 95% 56,072,1) y un VPN del 87,1% (IC 95% 84,789,2). CONCLUSIONES: Más de la mitad de los sujetos con infección por SARS-CoV-2 presentan DO o DG. La presencia de DO o de DG podría ser de utilidad diagnostica por su capacidad para predecir la infección en más de la mitad de las ocasiones.

There is limited information on the characteristics, prognostic factors, and outcomes of patients with multiple myeloma (MM) hospitalized with COVID-19. This retrospective case series investigated 167 patients reported from 73 hospitals within the Spanish Myeloma Collaborative Group network in March and April, 2020. Outcomes were compared with 167 randomly selected, contemporary, age-/sex-matched noncancer patients with COVID-19 admitted at six participating hospitals. Among MM and noncancer patients, median age was 71 years, and 57% of patients were male; 75 and 77% of patients, respectively, had at least one comorbidity. COVID-19 clinical severity was moderate-severe in 77 and 89% of patients and critical in 8 and 4%, respectively. Supplemental oxygen was required by 47 and 55% of MM and noncancer patients, respectively, and 21%/9% vs 8%/6% required noninvasive/invasive ventilation. Inpatient mortality was 34 and 23% in MM and noncancer patients, respectively. Among MM patients, inpatient mortality was 41% in males, 42% in patients aged >65 years, 49% in patients with active/progressive MM at hospitalization, and 59% in patients with comorbid renal disease at hospitalization, which were independent prognostic factors on adjusted multivariate analysis. This case series demonstrates the increased risk and identifies predictors of inpatient mortality among MM patients hospitalized with COVID-19.

Background and Objectives: During the coronavirus disease 2019 (COVID-19) pandemic, virtual visits (VVs) were recommended as an innovative and necessary alternative for patients with heart failure (HF). To assess the feasibility and acceptability of VVs in patients with HF, pulmonary hypertension (PH), and heart transplant (HT). Methods: We designed a single-centre cohort study. Consecutive VVs performed in our HF unit were analysed. The period comprehended between January 1st and March 19th (before COVID-19) and March 20th and June 30th (during COVID-19) was compared. We assessed acceptability, feasibility and the need for diagnostic studies, in-person medical evaluation, and hospitalization at 30 days. Results: HF unit medical doctors conducted 22 VVs in the pre-COVID period and 416 VVs during the COVID period. The VV was able to be performed in all patients scheduled for it and 44% answered the survey. Ninety percent of the patients who answered the survey strongly agreed that VVs were easy to be carried out. All the patients "strongly agreed" or "agreed" that their health problem could be resolved. Most patients (95%) rated the global experience as very good or excellent, with an overall average rate of 9.76±0.5 out of 10. We found no differences regarding the requirement of diagnostic studies, in-person medical evaluation and hospitalization during the first month after VVs between the 2 periods. Conclusions: VVs were feasible, presented high acceptability, and the overall experience was positive in patients with HF, PH, and HT, being this modality a valuable tool that complements in-person care.
RESUMEN
INTRODUCTION: The past few years have given rise to extensive research on an interatrial block and its clinical relevance, mainly its association with supraventricular arrhythmias. In 2015, the authors of this article reviewed the Bayes syndrome for the first time and after three years there has been so much evidence accumulated that it seems reasonable to rewrite an update, based fundamentally on the new findings. Focused on its relationship with cardioembolic strokes, today efforts are being targeted at understanding its pathophysiology, its diagnosis, and its prognostic implications, in order to learn if it should be treated. Areas covered: A non-systematic review of the literature was developed using the Pubmed and Cochrane databases, focusing on randomized clinical trials and large observational studies that evaluated new physiopathological and epidemiological aspects, new clinical scenarios in which it has been assessed and its association with dementia. Finally, those studies that proposed new possible treatments were reviewed. Expert commentary: Interatrial block is not only a predictor of supraventricular arrhythmias, is a subclinical disease that might be considered as a marker of risk for adverse outcomes. Although there is some evidence to suggest that early treatment may be beneficial, potential therapies have yet to be investigated.

INTRODUCTION: Until recently, vitamin K antagonists (VKA) were the only drugs available for long-term anticoagulation. The use of these drugs is laborious due to their variable pharmacokinetics and pharmacodynamics. The advent of direct oral anticoagulants has produced a paradigm shift due to their low incidence of drug interactions, their stable plasma levels, and their lack of monitoring. Rivaroxaban, a factor Xa inhibitor, has been tested in different clinical scenarios and has proved to be effective and safe, even increasing the scope of the old VKA. Areas covered: A non-systematic review of the literature was conducted using the PubMed and Cochrane databases, focusing on randomized clinical trials and real-world observational studies that evaluated rivaroxaban in patients with atrial fibrillation, venous thromboembolism, and atherosclerotic coronary and peripheral vascular disease. Expert commentary: The role of rivaroxaban keeps expanding into areas that were unimaginable few years ago, in the light of solid evidence that has eliminated old strict paradigms. Nonetheless, it will be necessary to adjust costs and better understand the perceived barriers to its widespread implementation, to get fully acceptation of rivaroxaban for the different clinical conditions that have been suggested.

Introducción: Los errores de prescripción son un problema frecuente que amenaza la seguridad de los pacientes internados, especialmente en áreas de cuidados críticos. Objetivo: Evaluar la efectividad de un proyecto de mejora de la calidad para reducir errores de prescripción en pacientes internados por patologías de origen cardiovascular. Material y métodos: Se implementó un proyecto de mejora de la calidad destinado a reducir errores de prescripción intrahos-pitalaria. Los tres componentes principales del proyecto fueron: supervisión obligatoria de las indicaciones, utilización de un software que ordena las indicaciones por sistemas biológicos e implementación de una norma de formato universal de prescripción de medicamentos, que incluyó un diccionario de abreviaturas y de diluciones normalizadas. Con anterioridad a la implementación de estos cambios se midió la cantidad de errores de prescripción semanales, estratificados por área de internación. Se analizó el impacto del proyecto dividiendo las muestras en cuatro períodos consecutivos de 9 semanas cada uno (un período preintervención y tres posintervención) y se comparó luego la cantidad de errores detectados en cada uno de ellos. En cada período se evaluaron de manera aleatoria las indicaciones de 180 pacientes. Resultados: Se analizaron en total 720 prescripciones. La implementación del proyecto de mejora logró reducir la cantidad de errores de manera rápida y sostenida en el tiempo (mediana preintervención de 85, RIC 70-95 y mediana final de 26, RIC 21-37; p = 0,0004). Conclusión: El proyecto de mejora de la calidad implementado permitió reducir significativamente la cantidad de errores de prescripción en pacientes internados por patologías cardiovasculares.
RESUMEN
BACKGROUND: The cholesteryl ester transfer protein inhibitor evacetrapib substantially raises the high-density lipoprotein (HDL) cholesterol level, reduces the low-density lipoprotein (LDL) cholesterol level, and enhances cellular cholesterol efflux capacity. We sought to determine the effect of evacetrapib on major adverse cardiovascular outcomes in patients with high-risk vascular disease. METHODS: In a multicenter, randomized, double-blind, placebo-controlled phase 3 trial, we enrolled 12,092 patients who had at least one of the following conditions: an acute coronary syndrome within the previous 30 to 365 days, cerebrovascular atherosclerotic disease, peripheral vascular arterial disease, or diabetes mellitus with coronary artery disease. Patients were randomly assigned to receive either evacetrapib at a dose of 130 mg or matching placebo, administered daily, in addition to standard medical therapy. The primary efficacy end point was the first occurrence of any component of the composite of death from cardiovascular causes, myocardial infarction, stroke, coronary revascularization, or hospitalization for unstable angina. RESULTS: At 3 months, a 31.1% decrease in the mean LDL cholesterol level was observed with evacetrapib versus a 6.0% increase with placebo, and a 133.2% increase in the mean HDL cholesterol level was seen with evacetrapib versus a 1.6% increase with placebo. After 1363 of the planned 1670 primary end-point events had occurred, the data and safety monitoring board recommended that the trial be terminated early because of a lack of efficacy. After a median of 26 months of evacetrapib or placebo, a primary end-point event occurred in 12.9% of the patients in the evacetrapib group and in 12.8% of those in the placebo group (hazard ratio, 1.01; 95% confidence interval, 0.91 to 1.11; P=0.91). CONCLUSIONS: Although the cholesteryl ester transfer protein inhibitor evacetrapib had favorable effects on established lipid biomarkers, treatment with evacetrapib did not result in a lower rate of cardiovascular events than placebo among patients with high-risk vascular disease.

Polyunsaturated fatty acids (PUFA) contained in fish oil (FO) are ligands for peroxisome proliferator-activated receptors (PPAR) that may induce changes in cardiometabolic markers. Variation in PPAR genes may influence the beneficial responses linked to FO supplementation in young adults. The study aimed to analyze the effect of FO supplementation on glucose metabolism, circulating lipids and inflammation according to PPARα L162V and PPARγ2 P12A genotypes in young Mexican adults. 191 young, non-smoking subjects between 18 and 40 years were included in a one-arm study. Participants were supplemented with 2.7 g/day of EPA+DHA, during six weeks. Dietary analysis, body composition measurements and indicators for glucose metabolism, circulating lipids, and markers for inflammation were analyzed before and after intervention. An overall decrease in triglycerides (TG) and an increase in HS-ω3 index were observed in all subjects [-4.1 mg/dL, (SD:±51.7), P=.02 and 2.6%, (SD:±1.2), P<.001 respectively]. Mean fasting insulin and glycated hemoglobin (HbA1c%) were significantly decreased in all subjects [-0.547mlU/L, (SD:±10.29), P=.034 and-0.07%, (SD:±0.3), P<.001 respectively], whereas there was no change in body composition, fasting glucose, adiponectin and inflammatory markers. Subjects carrying the minor alleles of PPARα L162V and PPARγ2 P12A had higher responses in reduction of TG and fasting insulin respectively. Interestingly, doses below 2.7 g/day (1.8 g/day) were sufficient to induce a significant reduction in fasting insulin and HbA1c% from baseline (P=.019 and P<.001). The observed responses in triglycerides and fasting insulin in the Mexican population give further evidence of the importance of FO supplementation in young people as an early step towards the prevention of cardiometabolic disease.

The prevalence of left ventricular noncompacted myocardium (LVNC) is not clearly defined yet. The goal of this study was to prospectively assess the prevalence of LVNC in a population of patients assessed for cardiovascular disease and to analyze the coincidence between observers using the echocardiographic criteria for diagnosis of LVNC. We included patients prospectively during a 1-year period. To analyze the concordance between different observers, we performed a blind analysis of 50 patients between 7 operators to calculate Kappa index for each criteria. The analysis of concordance for final diagnosis of LVNC was free-marginal kappa: 0.94. A total of 10,857 patients underwent echocardiography; 2,931 (27%) were normal. LVNC was found in 26 patients (prevalence = 0.24%), 16 patients were women, mean age of 52.6 years. Patients were divided into 2 groups; group A: ejection fraction (EF) <50% (n = 20) and group B: normal systolic function (n = 6). Among abnormal studies, 294 (2.7%) were dilated cardiomyopathies (DCs) Patients with LVNC and EF <50% comprised 6.8% of DC (20 of 294) and 24% (20 of 75) of patients with idiopathic DC (p <0.0001). Group A patients were older and with less presence of women (both p <0.05). In conclusion, the prevalence of LVNC in a population assessed for cardiovascular diseases is low. In contrast, it is very high in the subgroup of patients with idiopathic DC. The group of patients with LVNC and normal LVEF is younger and with a higher presence of women than those with LVNC and depressed LVEF. Coincidence between operators is very good for the identification of echocardiographic criteria.

BACKGROUND: The aim of the study was to evaluate the value of high-sensitivity cardiac troponin (hs-cTn) for identifying high-risk patients. METHODS AND RESULTS: One hundred and eighty-seven patients admitted with acute heart failure (HF) (without myocardial infarction) were consecutively included; hs-cTn was measured at admission; the relation between elevated hs-cTn and the clinical outcome during hospitalization and at 90 days was analyzed; 93% (n = 174) had hs-cTn above the maximal normal value (14 ng/L); median hs-cTn was 42 ng/L (IQR 24-81). Patients with ejection fraction (EF) ≤ 45% had higher hs-cTn values (p = 0.0004). Patients with low cardiac output syndrome (LCOS) or shock had higher troponin levels compared with those with less severe clinical presentations (p = 0.004). Patients who required inotropic presented higher troponin values (p = 0.002), troponin values were also higher in those requiring complex therapies (intra-aortic balloon pump, mechanical ventilation or hemodialysis, p = 0.002). At 90-day follow-up, 28 (15.5%) patients died and 27 rehospitalizations occurred (55 events). The risk of events was greater in patients with hs-cTn > 42 ng/L (0.021), low blood pressure at admission (p = 0.002), LCOS or shock (p < 0.0001), EF ≤ 45% (p = 0.005) and inotropic use (p < 0.0001). In multivariate analysis, only inotropic agents requirements was associated independently with a high risk of death or rehospitalizations at 90 days (p = 0.007). CONCLUSIONS: Elevation of hs-cTn is a finding almost constant in patients with decompensated HF. In subjects with higher troponin levels ventricular dysfunction is frequent. The use of hs-cTn for risk stratification at admission helps to identify populations with poor outcome during hospitalization and increased risk of death or rehospitalizations during follow-up who will require rapid implementation of aggressive treatment.
