Nutritional Support Reduces Circulating Cytokines in Patients with Heart Failure.

Increased inflammation is associated with the pathogenesis of heart failure (HF). Increased circulating levels of cytokines have been previously reported and generally associated with worse clinical outcomes. In this context, the modulation of inflammation-related parameters seems to be a reasonable therapeutic option for improving the clinical course of the disease. Based on this, we aimed to compare changes in circulating cytokines when Mediterranean diet alone or in combination with hypercaloric, hyperproteic oral nutritional supplements (ONS), enriched with omega-3 (n-3) polyunsaturated fatty acids were administered to patients with HF. Briefly, patients were randomly assigned to receive Mediterranean Diet (control group) vs. Mediterranean Diet plus ONS (intervention group). We observed increased circulating levels of IL-6, IL-8, MCP-1 and IP-10. MCP-1 and IL-6 were associated with overweight and obesity (p = 0.01-0.01-0.04, respectively); IL-6 and IL-8 were positively correlated with fat mass and CRP serum levels (p = 0.02-0.04, respectively). Circulating levels of IL-8 significantly decreased in all patients treated with the Mediterranean diet, while IL-6 and IP-10 only significantly decreased in patients that received plus ONS. In the univariate analysis, MCP-1 and its combination with IL-6 were associated with increased mortality (p = 0.02), while the multivariate analysis confirmed that MCP-1 was an independent factor for mortality (OR 1.01, 95%ci 1.01-1.02). In conclusion, nutritional support using hypercaloric, hyperproteic, n-3 enriched ONS in combination with Mediterranean Diet was associated with decreased circulating levels of some cytokines and could represent an interesting step for improving heart functionality of patients with HF.

Differences in the Evaluation of Malnutrition and Body Composition Using Bioelectrical Impedance Analysis, Nutritional Ultrasound, and Dual-Energy X-ray Absorptiometry in Patients with Heart Failure.

BACKGROUND: Although malnutrition is frequently observed in patients with heart failure (HF), this diagnosis should be performed carefully since HF itself is associated with increased inflammatory activity, which affects body weight, functionality, and some nutritional parameters; thus, its isolated interpretation can erroneously identify surrogate markers of severity as markers of malnutrition. In this context, we aimed to evaluate the prevalence of malnutrition using different classification systems and perform a comprehensive nutritional evaluation to determine the reliability of different diagnostic techniques. PATIENTS AND METHODS: Eighty-three patients with a recent hospital admission due to HF were evaluated. GLIM diagnosis criteria and subjective global assessment (SGA) were performed; a comprehensive anthropometric, functional, and biochemical nutritional evaluation was performed, in which bioelectrical impedance analysis (BIA), nutritional ultrasound, and dual-energy X-ray absorptiometry (DXA) were performed. Additionally, mortality and additional admissions due to HF were determined after a mean follow up of 18 months. RESULTS: Malnutrition according to the GLIM criteria (54%) accurately distinguished patients with impaired functionality, lower lean mass, skeletal mass index, and appendicular muscle mass (BIA), as well as lower trunk fat mass, trunk lean mass, fat-free mass (DXA), and decreased albumin and increased C-reactive protein serum levels. According to SGA, there were significant changes in body composition parameters determined by BIA, muscle ultrasound, and functional tests between well-nourished patients and patients with risk of malnutrition (53.7%) or who had malnutrition (7.1%), but not when the last two groups were compared. BIA and DXA showed strong correlations when evaluating muscle and fat mass in HF patients, but correlations with nutritional ultrasound were limited, as well as functional tests. A multivariate analysis showed that no significant association was observed between body composition and mortality, but preperitoneal fat was associated with an increased risk of new hospital admissions (OR: 0.73). CONCLUSIONS: GLIM criteria identified a lower percentage of patients with HF and malnutrition compared with SGA; thus, SGA could have a role in preventing malnutrition in HF patients. Nutritional evaluation with BIA and DXA in patients with HF showed reliable results of body composition parameters in HF, and both help with the diagnosis of malnutrition according to the GLIM or SGA criteria and could provide complementary information in some specific cases.

Right Ventricular Function in Long-Term Survivors of Childhood Acute Lymphoblastic Leukemia: From the CTOXALL Study.

There are limited data regarding right ventricle (RV) impairment in long-term survivors of childhood acute lymphoblastic leukemia (CLS). The aim of this study was to assess RV function in these patients using echocardiographic conventional measurements and automated RV strain. Echocardiographic recordings of 90 CLS and 58 healthy siblings from the CTOXALL cohort were analyzed. For group comparisons, inverse probability weighting was used to reduce confounding. The CLS group (24.6 ± 9.7 years, 37.8% women) underwent an echocardiographic evaluation 18 (11-26) years after the diagnosis. RV systolic dysfunction was found in 16.7% of CLS individuals using RV free-wall strain (RVFWS) compared to 2.2 to 4.4% with conventional measurements. RV systolic function measurements were lower in the CLS than in the control group: TAPSE (23.3 ± 4.0 vs. 25.2 ± 3.4, p = 0.004) and RVFWS (24.9 ± 4.6 vs. 26.8 ± 4.7, p = 0.032). Modifiable cardiovascular risk factors such as obesity (p = 0.022) and smoking (p = 0.028) were independently associated with reduced RVFWS. In conclusion, RV systolic function impairment was frequent in long-term survivors of childhood leukemia, underscoring the importance of RV assessment, including RVFWS, in the cardiac surveillance of these patients.

The Worsening of Heart Failure with Reduced Ejection Fraction: The Impact of the Number of Hospital Admissions in a Cohort of Patients.

BACKGROUND: Worsening heart failure (WFH) includes heart failure (HF) hospitalisation, representing a strong predictor of mortality in patients with heart failure with reduced ejection fraction (HFrEF). However, there is little evidence analysing the impact of the number of previous HF admissions. Our main objective was to analyse the clinical profile according to the number of previous admissions for HF and its prognostic impact in the medium and long term. METHODS: A retrospective study of a cohort of patients with HFrEF, classified according to previous admissions: cohort-1 (0-1 previous admission) and cohort-2 (≥2 previous admissions). Clinical, echocardiographic and therapeutic variables were analysed, and the medium- and long-term impacts in terms of hospital readmissions and cardiovascular mortality were assessed. A total of 406 patients were analysed. RESULTS: The mean age was 67.3 ± 12.6 years, with male predominance (73.9%). Some 88.9% (361 patients) were included in cohort-1, and 45 patients (11.1%) were included in cohort-2. Cohort-2 had a higher proportion of atrial fibrillation (49.9% vs. 73.3%; p = 0.003), chronic kidney disease (36.3% vs. 82.2%; p < 0.001), and anaemia (28.8% vs. 53.3%; p = 0.001). Despite having similar baseline ventricular structural parameters, cohort-1 showed better reverse remodelling. With a median follow-up of 60 months, cohort-1 had longer survival free of hospital readmissions for HF (37.5% vs. 92%; p < 0.001) and cardiovascular mortality (26.2% vs. 71.9%; p < 0.001), with differences from the first month. CONCLUSIONS: Patients with HFrEF and ≥2 previous admissions for HF have a higher proportion of comorbidities. These patients are associated with worse reverse remodelling and worse medium- and long-term prognoses from the early stages, wherein early identification is essential for close follow-up and optimal intensive treatment.

Mediterranean Diet, Vitamin D, and Hypercaloric, Hyperproteic Oral Supplements for Treating Sarcopenia in Patients with Heart Failure-A Randomized Clinical Trial.

BACKGROUND: Malnutrition and sarcopenia frequently affect patients with heart failure (HF), in which clinical outcomes and survival is decreased. Thus, appropriate nutritional screening and early nutrition support are highly recommended. Currently, nutritional support is not a standard of care in patients with HF, and the use of commercially available oral supplements (OSs) could provide an additional benefit to medical treatment in these patients. AIM: To compare the effect of the Mediterranean diet in combination with hypercaloric, hyperproteic OS in patients with HF. PATIENTS AND METHODS: An open label, controlled clinical study in which patients were randomly assigned to receive a Mediterranean diet (control group) vs. hypercaloric, hyperproteic OS (intervention group) for twenty-four weeks. Thirty-eight patients were included; epidemiological, clinical, anthropometric, ultrasound (muscle echography of the rectus femoris muscle of the quadriceps and abdominal adipose tissue), and biochemical evaluations were performed. All patients received additional supplementation with vitamin D. RESULTS: Baseline malnutrition according to the GLIM criteria was observed in 30% of patients, while 65.8% presented with sarcopenia. Body cell mass, lean mass, and body mass increased in the intervention group (absolute increase of 0.5, p = 0.03, 1.2 kg, p = 0.03, and 0.1 kg, p = 0.03 respectively). In contrast, fat mass increased in the control group (4.5 kg, p = 0.05). According to the RF ultrasound, adipose tissue, muscle area, and circumference tended to decrease in the intervention group; it is probable that 24 weeks was too short a period of time for evaluating changes in muscle area or circumference, as previously observed in another group of patients. In contrast, functionality, determined by the up-and-go test, significantly improved in all patients (difference 12.6 s, p < 0.001), including the control (10 s improvement, p < 0.001) and the intervention group (improvement of 8.9 s, p < 0.001). Self-reported QoL significantly increased in all groups, from 68.7 ± 22.2 at baseline to 77.7 ± 18.7 (p = 0.01). When heart functionality was evaluated, LVEF increased in the whole cohort (38.7 ± 16.6 vs. 42.2 ± 8.9, p < 0.01); this increase was higher in the intervention group (34.2 ± 16.1 at baseline vs. 45.0% ± 17.0 after 24 weeks, p < 0.05). Serum values of NT-proBNP also significantly decreased in the whole cohort (p < 0.01), especially in the intervention group (p = 0.02). After adjusting by age and sex, nutritional support, baseline LVEF, NT-proBNP, and body composition parameters of functionality tests were not associated with mortality or new hospital admissions in this cohort. CONCLUSION: Nutritional support with hypercaloric, hyperproteic OS, Mediterranean diet, and vitamin D supplementation were associated with decreased NT-proBNP and improvements in LVEF, functionality, and quality of life in patients with HF, despite a significant decrease in hospital admissions.

Congenital complete absence of pericardium in a young woman with non-specific symptoms.

Congenital absence of the pericardium is a very rare entity that is usually asymptomatic and hence difficult to diagnose. However, cases of sudden death have been reported in patients with partial pericardial defects (even asymptomatic ones), and such patients require surgical treatment. We report the case of a 17-year-old patient with complete pericardial agenesis (diagnosed by chance during a cardiological consultation) and briefly review the radiological findings of this entity.

Etiologic spectrum and clinical features of mitral regurgitation in a Spanish population.

BACKGROUND AND AIM OF THE STUDY: The study aim was to investigate the etiologic spectrum of at least moderate mitral regurgitation (MR) in patients at a tertiary care center in a Spanish region. METHODS: All patients referred for echocardiography with moderate or severe MR, assessed according to the guidelines of the American Society of Echocardiography, were included prospectively in the study. RESULTS: Between October 2006 and February 2008, a total of 276 patients (157 females, 119 males; mean age 61 +/- 20 years) were enrolled into the study. At the time of evaluation, 67% of the patients were outpatients and the remainder were hospitalized. The NYHA functional class was III-IV in 31% of patients. The main echocardiographic data were: color flow jet area 11 +/- 5 cm2, vena contracta 6.7 +/- 1.9 mm, effective regurgitant orifice area 0.46 +/- 0.28 cm2, left ventricular diastolic and systolic diameters 58 +/- 10 mm and 39 +/- 12 mm, respectively, left ventricular ejection fraction 0.55 +/- 0.19, and pulmonary artery systolic pressure 39 +/- 16 mmHg. The MR was degenerative in 42% of patients, rheumatic in 22%, functional due to idiopathic dilated cardiomyopathy in 18%, functional due to ischemic cardiomyopathy in 7%, congenital in 7%, and had other causes in 4%. CONCLUSION: Among this Spanish population, the majority of the moderate or severe MR encountered was organic, with degenerative mitral disease as the most common etiology. Functional regurgitation was present in a significant proportion of patients, with idiopathic dilated cardiomyopathy being the most frequent cause.

Influencia de la desnutrición en la mortalidad a largo plazo de pacientes hospitalizados por insuficiencia cardiaca / Impact of malnutrition on long-term mortality in hospitalized patients with heart failure

Introducción y objetivos. Actualmente se desconoce la prevalencia de desnutrición entre los pacientes con insuficiencia cardiaca y el papel que este estado pudiera tener en su pronóstico. El objetivo de este estudio es analizar la prevalencia y riesgo de desnutrición y su posible influencia en la mortalidad a largo plazo de los pacientes con insuficiencia cardiaca. Métodos. Se analizó prospectivamente a 208 pacientes dados de alta consecutivamente desde nuestro centro entre enero de 2007 y marzo de 2008 tras un ingreso por insuficiencia cardiaca. Antes del alta, se realizó una completa valoración nutricional y se realizó el diagnóstico de desnutrición y riesgo de desnutrición mediante la encuesta Mini Nutritional Assessment. Su posible asociación independiente con la mortalidad se valoró mediante un análisis multivariable de Cox. Resultados. La media de edad fue 73±10 años, el 46% eran mujeres y la etiología más frecuente de la insuficiencia cardiaca fue la isquémica (41%). El 13% de los pacientes fueron clasificados como desnutridos; el 59,5%, en riesgo de desnutrición y el 27,5%, bien nutridos. A los 25 meses (mediana de seguimiento), la mortalidad en los tres grupos fue del 76, el 35,9 y el 18,9% respectivamente (log-rank test, p<0,001). En el análisis multivariable de Cox, el estado de desnutrición resultó ser un predictor independiente de mortalidad (hazard ratio=3,75; intervalo de confianza del 95%, 1,75-8,02; p=0,001). Conclusiones. La desnutrición y el de riesgo de desnutrición alcanzan una prevalencia elevada en pacientes hospitalizados por insuficiencia cardiaca. Además, hemos encontrado que el estado de desnutrición definido mediante el Mini Nutritional Assessment es un predictor independiente de mortalidad en estos pacientes (AU)

A prospective analysis was conducted on 208 patients discharged consecutively from our centre between January 2007 and March 2008 after being hospitalised with heart failure. Before discharge, a complete nutritional assessment was performed and diagnosis of malnutrition and risk of malnutrition was done with the Mini Nutritional Assessment. Its possible independent association with mortality was assessed by a Cox multivariate analysis. Results. The mean age of the patients was 73±10 years, with 46% women; the most common aetiology of heart failure was ischaemia (41%). In addition, 13% were classified as malnourished, 59.5% at risk of malnutrition and 27.5% were well-nourished. At a median follow-up of 25 months, mortality in the three groups was 76%, 35.9% and 18.9%, respectively (log-rank, P<.001). In the Cox multivariate analysis, the malnutrition state was an independent predictor of mortality (hazard ratio 3.75, 95% confidence interval, 1.75-8.02, P=.001). Conclusions. Malnutrition and the risk of malnutrition are highly prevalent in patients hospitalised for heart failure. Furthermore, we found that the state of malnutrition as defined by the Mini Nutritional Assessment survey is an independent predictor of mortality in these patients (AU)

Measurement of aortic valve annulus using different cardiac imaging techniques in transcatheter aortic valve implantation: agreement with finally implanted prosthesis size.

AIMS: To compare the measurements of the aortic annulus obtained with various imaging techniques in patients with severe aortic stenosis scheduled for transcatheter aortic valve implantation, and to determine the grade of agreement between the predicted size of the prosthesis for each technique, and the size of the finally implanted valve. METHODS AND RESULTS: The aortic annulus was measured in 40 patients treated by transcatheter aortic valve implantation (CoreValve aortic valve) with transthoracic (TTE) and transesophageal echocardiography (TEE), 64-slice tomography, and angiography. A large valve was implanted when annulus was >23 mm and a small one if it was ≤23 mm. If the size of the prosthesis predicted by several techniques was not the same in one case, we selected the size in which more techniques presented agreement. Forty aortic valves, 26 small and 14 large, were implanted percutaneously. The best correlation was obtained with TTE and TEE (r = 0.93, P < 0.001). The correlation of TTE and TEE with angiography also was good (r = 0.58, P < 0.001 and r = 0.53, P < 0.001, respectively). Correlations between these techniques and computed tomography were poor (P = NS for all comparisons). The best agreement between estimated aortic annulus and implanted valve size was obtained with transtoracic and TEE (κ= 0.88 and 0.76). CONCLUSIONS: The aortic annulus measurements obtained by TTE, TEE, and angiography correlated well, while tomography correlated poorly with other techniques. The imaging techniques that showed the best agreement between estimated aortic annulus size and implanted aortic valve size were TTE and TEE.

Use of the venture wire-control catheter for accessing side branches during provisional stenting: an option for bifurcations with an unfavorable anatomy.

We report our experience with the Venture wire-control catheter in 20 patients with bifurcation lesions in which it was impossible to access the side branch using conventional techniques. This device was always used as a last resort and was employed during different stages in the treatment of the bifurcation lesions (i.e. initially, after stenting of the main vessel or both). In 17 patients (85%), use of the Venture catheter resulted in the success of the procedure. Only one complication associated with a monorail catheter was recorded. It was resolved successfully. One patient died from heart failure 10 days after the procedure and two patients, in whom it was impossible to access the side branch, had non-Q-wave myocardial infarctions. In conclusion, the Venture catheter was effective and safe, and enabled the side branches of complex bifurcation lesions to be accessed.

Utilidad del catéter Venture para acceder al ramo lateral en la técnica de stent provisional: una alternativa para bifurcaciones con anatomías desfavorables / Use of the venture wire-control catheter for accessing side branches during provisional stenting: an option for bifurcations with an unfavorable anatomyd

Describimos nuestra experiencia con el catéter Venture en 20 pacientes con lesiones en bifurcación en los que fue imposible cruzar al ramo lateral con la tecnología habitual.

Prevalence of patent foramen ovale determined by transesophageal echocardiography in patients with cryptogenic stroke aged 55 years or older. Same as younger patients?

INTRODUCTION AND OBJECTIVES: To investigate the relationship between patent foramen ovale and cryptogenic stroke in patients aged > or =55 years. METHODS: This prospective study determined the presence of patent foramen ovale and atrial septal aneurysm using transesophageal echocardiography in 262 consecutive patients with a diagnosis of probable cryptogenic stroke. Data from 44 patients aged > or =55 years with cryptogenic stroke (Group A) were compared with those from two other groups: 194 patients aged <55 years with cryptogenic stroke (Group B) and 24 control patients aged > or =55 years with stroke of known origin, namely grade III-V aortic atheromatosis (Group C). RESULTS: The frequency of patent foramen ovale in Group A was similar to that in Group B (38% vs. 36%; P=.85) but significantly higher than that in Group C (38% vs. 8%; P=.029). The frequency of patent foramen ovale with concomitant atrial septal aneurysm was significantly higher in the study group (Group A) than in the control Group C (18% vs. 0; P=.039) and non-significantly higher than in Group B (18% vs. 11%; P=.11). CONCLUSIONS: The frequency of patent foramen ovale alone or in association with atrial septal aneurysm in patients with cryptogenic stroke aged > or =55 years was similar to that in those aged <55 years, but higher than that in patients aged > or =55 years with stroke of atherosclerotic origin. These data suggest that paradoxical embolism could be a cause of stroke in both age groups.
