INTRODUCTION AND OBJECTIVES: Left atrial appendage closure can be an attractive option for patients with nonvalvular atrial fibrillation and a contraindication to oral anticoagulants, provided that satisfactory results can be achieved during implantation and follow-up. METHODS: Thirty-five consecutive patients, not eligible for randomized trials with oral anticoagulants, had an Amplatzer occlusion device implanted under general anesthesia. After the first 5 patients, 3-dimensional imaging was incorporated. The results of the implantation and the follow-up were analyzed over a 1-year period. RESULTS: The mean age was 74.65 (7.61) years, with a CHADS(2) score of 2.41 (1.53) and a CHA(2)DS(2)-VASc score of 3.17 (1.60). Implantation failed in 1 patient and 5 needed a change in the selected plug size. There were no cardiac complications during the implantation or hospital stay. There was 1 vascular complication (arteriovenous fistula). Transesophageal echocardiography monitoring was performed at 24h, 1, 3, 6 and 12 months and we found 5 thrombi which were resolved with heparin. In the follow-up period of 21.14 (10.09) months, 3 patients aged>80 years died, none of them due to heart problems, and one transient ischemic stroke without further consequences. CONCLUSIONS: Left atrial appendage closure by an experienced operator can be a treatment option with few complications and with efficient results at>1 year in reducing thromboembolic and hemorrhagic complications, even in very high-risk groups.

INTRODUCTION AND OBJECTIVES: Obesity is a major cardiovascular risk factor. In Spain, few studies have physically measured height and weight to estimate the magnitude of the problem. The aim of this study was to determine the prevalence of child and adolescent obesity in Spain in 2012. METHODS: We performed a cross-sectional probability sample of 1018 children, representative of the Spanish population aged between 8 and 17 years old, with objectively measured height and weight, along with other sociodemographic variables. We calculated the prevalence of overweight and obesity according to the criteria of the World Health Organization, the International Obesity Task Force, and the enKid study. RESULTS: In the group aged 8 to 17 years old, the prevalence of overweight and obesity was 26% and 12.6%, respectively; 4 in 10 young people were overweight or obese. Excess weight was found in 45% of the group aged 8 to 13 years and in 25.5% of that aged 14 to 17 years. This cardiovascular risk factor was associated with lower social class and lower educational level. CONCLUSIONS: The prevalence of overweight and obesity in children and adolescents in Spain remains high (close to 40%), but has not increased in the last 12 years.

Patients with type 2 diabetes and revascularized coronary disease are a group with very high cardiovascular risk that has been rarely studied. This ICP-Bypass substudy analyzes the clinical characteristics and risk factor control of these patients.

Up to 4% of patients with acute chest pain, normal electrocardiogram, and negative troponins present major adverse cardiac events as a result of undiagnosed acute coronary syndrome. Our aim was to compare the diagnostic performance of multidetector computed tomography and exercise echocardiography in patients with a low-to-intermediate probability of coronary artery disease.

A multitude of studies have been published on the relationship between cardiovascular disease risk and a variety of nutrients, foods, and dietary patterns. Despite the well-accepted notion that diet has a significant influence on the development and prevention of cardiovascular disease, the foods considered healthy and harmful have varied over the years. This review aims to summarize the current scientific evidence on the cardioprotective effect of those foods and nutrients that have been considered healthy as well as those that have been deemed unhealthy at any given time in history. For this purpose, we reviewed the most recent literature using as keywords foods and nutrients (ie, meat, omega-3) and cardiovascular disease-related terms (ie, cardiovascular diseases, stroke). Emphasis has been placed on meta-analyses and Cochrane reviews. In general, there is a paucity of intervention studies with a high level of evidence supporting the benefits of healthy foods (ie, fruits and vegetables), whereas the evidence supporting the case against those foods considered less healthy (ie, saturated fat) seems to be weakened by most recent evidence. In summary, most of the evidence supporting the benefits and harms of specific foods and nutrients is based on observational epidemiological studies. The outcome of randomized clinical trials reveals a more confusing picture with most studies providing very small effects in one direction or another; the strongest evidence comes from dietary patterns. The current status of the relationship between diet and cardiovascular disease risk calls for more tailored recommendations based on genomic technologies.

Previous studies have reported that coronary intervention for complex lesions is independently correlated with major bleeding. The SYNTAX score is an angiographic tool used to grade the complexity of coronary artery diseases. The aim of this study was to assess the ability of the SYNTAX score to predict major bleeding following drug-eluting stent implantation.

In Spain, data based on large population-based cohorts adequate to provide an accurate prediction of cardiovascular risk have been scarce. Thus, calibration of the EuroSCORE and Framingham scores has been proposed and done for our population. The aim was to develop a native risk prediction score to accurately estimate the individual cardiovascular risk in the Spanish population.

The impact of atrial fibrillation on the prognosis of myocardial infarction is still the subject of debate. We analyzed the influence of previous and new-onset atrial fibrillation on in-hospital and long-term prognosis in patients with acute myocardial infarction.

Morbidity and mortality after admission for acute heart failure remain prohibitively high. In that setting, plasma levels of antigen carbohydrate 125 have shown to correlate with the severity of fluid overload and the risk of mortality and readmission. Preliminary data suggests a potential role of antigen carbohydrate 125 to guide therapy. The objective of this study is to evaluate the prognostic effect of an antigen carbohydrate 125-guided management strategy vs standard therapy in patients recently discharged for acute heart failure.
