Food consumption patterns related to excess weight and obesity in Spanish preschoolers.

PURPOSE: The aims of this study were (1) to identify the different food consumption patterns among Spanish preschoolers and (2) to examine the association between having a different food consumption pattern and the odds of having excess weight (i.e., overweight or obesity) or obesity among this population. METHODS: This was a nationwide cross-sectional study with data from the Spanish National Health Survey-2017. All preschoolers (aged 3-5 years) with complete information on all the variables analyzed were selected. The frequency of consumption of the fourteen food groups was evaluated by a food frequency questionnaire. Excess weight/obesity were computed following the World Health Organization criteria. A hierarchical cluster analysis using Ward's method (i.e., based on squared Euclidean distances) and k-means were performed including all food group consumption. A total sample of 663 was included in the cluster analysis. RESULTS: Three different clusters were established. Compared to the healthiest food consumption pattern (Cluster 1), higher odds of excess weight (OR = 1.51; CI: 95%, 1.02-2.25) and obesity (OR = 1.59; CI: 95%, 1.01-2.51) were found for participants with the unhealthiest food consumption pattern (Cluster 3). CONCLUSION: Having a food consumption pattern considered unhealthy (i.e., low intake of vegetables/fruits, high consumption of confectionery products, sugar-sweetened beverages, fast-food, and snacks) was associated with presenting excess weight/obesity among Spanish preschoolers. IMPACT: No studies have examined the specific food consumption patterns associated with excess weight or obesity among Spanish preschoolers. The unhealthiest food consumption pattern was characterized by a food consumption pattern that included a lower intake of vegetables and fruits and a higher consumption of confectionery products, sugar-sweetened beverages, fast-food, and snacks. Having a food consumption pattern considered unhealthy was associated with a higher prevalence of excess weight and obesity in comparison with other healthier food consumption patterns.

Safety and feasibility of transradial access for percutaneous coronary intervention in chronic total occlusions.

INTRODUCTION AND OBJECTIVES: Transfemoral access is the most frequently used vascular approach in chronic total occlusion percutaneous coronary interventions (CTO-PCI). The aim of this study was to evaluate the safety and feasibility of a transradial access CTO-PCI program and its impact on angiographic and clinical results and length of hospital stay. METHODS: Retrospective multicenter cohort study including 2550 consecutive CTO-PCI procedures included in a multicenter registry with accurate information on vascular access. A total of 896 procedures were performed as radial-only access while 1654 were performed through at least 1 femoral puncture. Clinical and angiographic data were collected. RESULTS: The mean age was 66.3± 11.4 years. The mean Japan-chronic total occlusion score (2.7±0.3) was similar in the 2 groups. Successful revascularization was achieved in 2009 (79.6%) cases, 78.2% and 82.1% in the femoral and radial access cohorts, respectively (P=.002). Periprocedural in-hospital complications were observed in 5.1% and 2.3% (P=.02), with fewer access site-dependant vascular complications in the transradial cohort (2.3% vs 0.2%; P=.009). The mean length of hospital stay was significantly shorter in the transradial access group (0.89±1.4 vs 2.2±3.2 days, P<.001). CONCLUSIONS: A transradial program for CTO-PCI is safe and effective in most CTO lesions. The transradial strategy has fewer vascular complications and shorter length of hospital stay without compromising the success rate.

Plaque modification in calcified chronic total occlusions: the PLACCTON study.

INTRODUCTION AND OBJECTIVES: Severe calcification is present in> 50% of coronary chronic total occlusions (CTOs) undergoing percutaneous intervention. We aimed to describe the contemporary use and outcomes of plaque modification devices (PMDs) in this context. METHODS: Patients were included in the prospective, consecutive Iberian CTO registry (32 centers in Spain and Portugal), from 2015 to 2020. Comparison was performed according to the use of PMDs. RESULTS: Among 2235 patients, wire crossing was achieved in 1900 patients and PMDs were used in 134 patients (7%), requiring more than 1 PMD in 24 patients (1%). The selected PMDs were rotational atherectomy (35.1%), lithotripsy (5.2%), laser (11.2%), cutting/scoring balloons (27.6%), OPN balloons (2.9%), or a combination of PMDs (18%). PMDs were used in older patients, with greater cardiovascular burden, and higher Syntax and J-CTO scores. This greater complexity was associated with longer procedural time but similar total stent length (52 vs 57mm; P=.105). If the wire crossed, the procedural success rate was 87.2% but increased to 96.3% when PMDs were used (P=.001). Conversely, PMDs were not associated with a higher rate of procedural complications (3.7 vs 3.2%; P=.615). Despite the worse baseline profile, at 2 years of follow-up there were no differences in the survival rate (PMDs: 94.3% vs no-PMDs: 94.3%, respectively; P=.967). CONCLUSIONS: Following successful wire crossing in CTOs, PMDs were used in 7% of the lesions with an increased success rate. Mid-term outcomes were comparable despite their worse baseline profile, suggesting that broader use of PMDs in this setting might have potential technical and prognostic benefits.

Percutaneous Intervention in Diffuse Coronary Disease: Overlapping Versus Single Very Long Stent Technique. Results From the OVERLONG Registry.

BACKGROUND: Both stent length and stent overlap are associated with worse outcomes in the percutaneous treatment of diffuse coronary artery disease (dCAD). However, evidence comparing these issues is scarce. We aimed to compare the results between the use of single very long stent (VLS) and ≥2 overlapping stents (OS) in the treatment of dCAD. METHODS: Seven hundred twenty-four consecutive lesions were included: 275 treated with a single VLS (≥40 mm) and 449 with ≥2 OS. Procedural characteristics were assessed, and survival analysis was performed to compare the incidence of major adverse cardiovascular events (MACE; composite of cardiovascular death, nonfatal myocardial infarction, target lesion revascularization [TLR], or stent thrombosis) during a median follow-up of 31 months. RESULTS: Procedures with VLS required less contrast volume (268 ± 122 vs 302 ± 113 cm3; P < .01), fluoroscopy time (16 ± 8 vs 21 ± 16 minutes; P < .01), and procedure duration (37 ± 18 vs 47 ± 27 minutes; P < .01) than the OS procedures. The VLS group showed lower incidence of MACE (4.4% vs 10.7%; P < .01), driven mainly by lower TLR rate (1.1% vs 4.7%; P < .01). The use of OS was an independent predictor of MACE. CONCLUSIONS: In this study, the use of VLS for the treatment of dCAD was associated with better outcomes compared to OS.

Long-Term Follow-Up of Percutaneous Coronary Intervention With Paclitaxel-Eluting Balloon Catheter.

Drug-eluting balloons currently constitute a therapeutic tool used in percutaneous coronary interventions (PCI). Long-term results remain unknown. We evaluated the prognosis of PCI using a second generation paclitaxel-eluting balloon (PEB) in real-world patients. We included all PCI with PEB in de novo or in-stent restenosis coronary lesions performed in our unit from March 2009 to March 2019. We assessed the composite of major adverse cardiovascular events (MACE) rate after a median follow-up of 42 months. Consecutive patients (n = 320) with 386 lesions were included; 46.9% presented with stable angina and 53.1% acute coronary syndromes; 52.6% of the lesions were in-stent restenosis and 47.3% de novo lesions with a mean diameter of 2.4 ± 0.5 mm. A bare metal stent was implanted in 6.7% and a drug-eluting stent in 8.5% of patients. The MACE rate was 8%: 10 (2.6%) cardiovascular deaths, 13 (3.4%) myocardial infarctions, and 16 (4.1%) target lesion revascularization. The all-cause death rate was 5.2%. No cases of thrombosis were recorded. In conclusion, PEB was a safe and effective tool to treat in-stent restenosis and de novo coronary lesions, especially small vessel disease, during long-term follow-up.

Biomarcadores inflamatorios y extensión de aterosclerosis coronaria en pacientes con síndrome coronario agudo: Estudio observacional prospectivo en un hospital general universitario / Circulating markers of inflammation and severity of coronary atherosclerosis in acute coronary syndrome: Prospective observational study in a general university hospital

Resumen Objetivo: Encontrar una relación entre los niveles de proteína C reactiva (PCR) y fibrinógeno, y la extensión de la aterosclerosis en el síndrome coronario agudo. Métodos: Estudio observacional prospectivo, en el que se incluyeron 873 pacientes con síndrome coronario atendidos en un hospital entre 2016 y 2018. Se analizaron niveles de PCR y fibrinógeno, marcadores metabólicos y extensión de la aterosclerosis coronaria. Resultados: No se halló correlación positiva entre los niveles de PCR y fibrinógeno y los marcadores metabólicos, así como tampoco con enfermedad de uno, dos y tres vasos (p 0,829; p 0,810). Conclusiones: Los niveles sanguíneos de PCR y fibrinógeno se relacionan con la tasa de eventos cardiovasculares, pero no se ha podido demostrar que exista relación entre estos y la severidad de la aterosclerosis coronaria.

Abstract Objective: To determine whether there is a relationship between C - reactive protein and fibrinogen levels and the extent of atherosclerosis in acute coronary syndrome. Methods: A prospective observational study was conducted that include 873 patients with coronary syndrome treated in a hospital between the years 2016 and 2018. An analysis was made that included C - reactive protein and fibrinogen levels, metabolic markers, extent of coronary atherosclerosis. Results: No positive correlation was found between the C - reactive protein and fibrinogen levels and the metabolic markers, nor with one, two, or three vessel disease (P=.829; P=.810). Conclusions: Although blood C-Reactive Protein and fibrinogen levels are associated with the rate of cardiovascular events, this study was unable to demonstrate whether there is a relationship between these and the severity of the coronary atherosclerosis.

Integral Velocidade-Tempo da Insuficiência Aórtica: Um Novo Marcador Ecocardiográfico na Avaliação da Gravidade da Insuficiência Aórtica / Velocity-Time Integral of Aortic Regurgitation: A Novel Echocardiographic Marker in the Evaluation of Aortic Regurgitation Severity

Resumo Fundamento A ecocardiografia é essencial para o diagnóstico e a quantificação da insuficiência aórtica (IA). A integral velocidade-tempo (IVT) do fluxo da IA pode estar relacionada à gravidade da IA. Objetivo Este estudo tem por objetivo avaliar se a IVT é um marcador ecocardiográfico de gravidade da IA. Métodos Foram incluídos todos os pacientes com IA nativa moderada ou grave e ritmo sinusal que visitaram o nosso laboratório de imagem entre janeiro e outubro de 2016. Todos os indivíduos foram submetidos a um ecocardiograma completo com medição da IVT da IA. A associação entre a IVT e a gravidade da IA foi analisada por regressão logística e modelos de regressão multivariada. Valores p<0,05 foram considerados estatisticamente significativos. Resultados Entre os 62 pacientes incluídos (68,5±14,9 anos; 64,5%: IA moderada; 35,5%: IA grave), a IVT foi maior em indivíduos com IA moderada em comparação àqueles com IA grave (2,2±0,5 m versus 1,9±0,5 m, p=0,01). Pacientes com IA grave apresentaram valores maiores de diâmetro diastólico final do ventrículo esquerdo (DDFVE) (56,1±7,1 mm versus 47,3±9,6 mm, p=0,001), volume diastólico final do ventrículo esquerdo (VDFVE) (171±36,5 mL versus 106±46,6 mL, p<0,001), orifício regurgitante efetivo (0,44±0,1 cm2 versus 0,18±0,1 cm2, p=0,002) e volume regurgitante (71,3±25,7 mL versus 42,5±10,9 mL, p=0,05), assim como menor fração de ejeção do ventrículo esquerdo (FEVE) (54,1±11,2% versus 63,2±13,3%, p=0,012). A IVT mostrou ser um marcador de gravidade da IA, independentemente do DDFVE, VDFVE e FEVE ( odds ratio 0,160, p=0,032) e da frequência cardíaca e pressão arterial diastólica (PAD) ( odds ratio 0,232, p=0,044). Conclusões A IVT do fluxo da IA apresentou associação inversa com a gravidade da IA, independentemente do diâmetro e volume do ventrículo esquerdo, frequência cardíaca, PAD e FEVE. A IVT pode ser um marcador de gravidade da IA em pacientes com IA nativa e ritmo sinusal. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0)

Abstract Background Echocardiography is essential for the diagnosis and quantification of aortic regurgitation (AR). Velocity-time integral (VTI) of AR flow could be related to AR severity. Objective This study aims to assess whether VTI is an echocardiographic marker of AR severity. Methods We included all patients with moderate or severe native AR and sinus rhythm who visited our imaging laboratory from January to October 2016. All individuals underwent a complete echocardiogram with AR VTI measurement. The association between VTI and AR severity was analyzed by logistic regression and multivariate regression models. A p-value<0,05 was considered statistically significant. Results Among the 62 patients included (68.5±14.9 years old; 64.5%: moderate AR; 35.5%: severe AR), VTI was higher in individuals with moderate AR compared to those with severe AR (2.2±0.5 m vs. 1.9±0.5 m, p=0.01). Patients with severe AR presented greater values of left ventricular end-diastolic diameter (LVEDD) (56.1±7.1 mm vs. 47.3±9.6 mm, p=0.001), left ventricular end-diastolic volume (LVEDV) (171±36.5 mL vs. 106±46.6 mL, p<0.001), effective regurgitant orifice (0.44±0.1 cm2vs. 0.18±0.1 cm2, p=0.002), and regurgitant volume (71.3±25.7 mL vs. 42.5±10.9 mL, p=0.05), as well as lower left ventricular ejection fraction (LVEF) (54.1±11.2% vs. 63.2±13.3%, p=0.012). The VTI proved to be a marker of AR severity, irrespective of LVEDD, LVEDV, and LVEF (odds ratio 0.160, p=0.032) and of heart rate and diastolic blood pressure (DBP) (odds ratio 0.232, p=0.044). Conclusions The VTI of AR flow was inversely associated with AR severity regardless of left ventricular diameter and volume, heart rate, DBP, and LVEF. VTI could be a marker of AR severity in patients with native AR and sinus rhythm. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0)

Clinical Prognosis Associated With the Use of Overlapping Stents With Homogenous Versus Heterogeneous Pharmacological Characteristics for the Treatment of Diffuse Coronary Artery Disease.

BACKGROUND: The clinical impact of percutaneous coronary intervention (PCI) and implantation of overlapping stents (OS) using platforms with the same versus different pharmacological characteristics is unknown. Our objective was to compare the outcomes of PCI with OS according to their pharmacological characteristics. METHODS: In this observational single-center registry, we included all PCI performed from April 2014 to December 2018 in which overlapping drug-eluting stents were implanted. Two groups were created according to whether the stents release the same drug [homogeneous: (HO)] or different [heterogeneous: (HE)]. The primary endpoint was the need for target lesion revascularization (TLR). Clinical assessment was performed after the procedure, bianually and at the end of follow-up (June 2019). RESULTS: 381 lesions with OS (HO: 209; HE: 172) were included (75.1% male, 66.7 ±â€¯11.6 years). Clinical presentation was stable coronary artery disease in 49.9%. Syntax score was 23.7 ±â€¯13.3. The number of OS implanted was 2.2 ±â€¯0.5 and the total stent length was 59.5 ±â€¯20.1 mm (HE: 61.5 ±â€¯21.6 vs. HO: 57.8 ±â€¯18.8 mm; p < 0.01). After a median follow-up of 21 months, the HE group showed a lower TLR rate than the HO group (HE:2.3% vs HO:7.2%; p = 0.03). The rates of cardiac death (p = 0.44), myocardial infarction (p = 0.36) and stent thrombosis (p = 0.85) were similar between groups. In the multivariate analysis, the OS with homogeneous-drug devices was an independent predictor of a higher rate of TLR. CONCLUSIONS: PCI using OS with homogeneous pharmacological characteristics was associated with a higher rate of TLR in comparison with the implantation of OS with heterogeneous pharmacological characteristics.

An Unusual Entity: Woven Coronary Artery Anomaly.

The recognition of woven coronary artery anomaly is difficult because of its rare nature. Optical coherence tomography imaging is challenging due to the tortuosity of the channels; however, it is crucial not only for the differential diagnosis but also to guide the treatment approach.

Magmaris Resorbable Magnesium Scaffold Implantation Assisted by Optical Coherence Tomography to Treat an Acute Coronary Dissection After a Blunt Chest Trauma.

Coronary Artery Tenting After Bypass Grafting: A Key Issue During Percutaneous Coronary Intervention of a Chronic Total Occlusion.

This image series shows how bypass grafts may tent the vessel to which they are anastomosed, potentially changing the expected course of the native coronary vessel. This fact must be taken into account during CTO-PCI, and this case emphasizes the importance of careful analysis of coronary anatomy with several angiographic projections.

Comparison of Clinical Outcomes Between Very Long Stents and Overlapping Stents for the Treatment of Diffuse Coronary Disease in Real Clinical Practice.

BACKGROUND: The stent length as well as the stent overlap for the percutaneous treatment of diffuse coronary disease have been considered predictors of adverse events. However, there are no comparative data on the use of very long stents or overlapping stents in this scenario. OBJECTIVE: To compare the clinical results of very long stents (≥40 mm) or overlapping stents in real clinical practice. METHODS: We included 643 lesions in 628 consecutive patients treated with a single very long stent (≥40 mm) (251 lesions) or ≥2 overlapped stents (392 lesions). We analyzed the procedural characteristics and the presentation of the combined endpoint [cardiovascular death, non-fatal myocardial infarction, need for target lesion revascularization or stent thrombosis] after a follow-up of 20 months. RESULTS: Total stent length was 54 ±â€¯18 mm and minimum diameter was 2.9 ±â€¯1.2 mm. At the end of follow-up, the rate of adverse events was 8.3% (cardiac death: 4.9%, myocardial infarction: 1.7%, target lesion revascularization: 3.1%, stent thrombosis: 0.7%). There were no significant differences between both groups in the presentation of the combined endpoint. Procedures with overlapping stents had more contrast volume (309 ±â€¯115 vs 273 ±â€¯127 ml; p = 0.002), longer duration (47 ±â€¯22 vs 39 ±â€¯18 min; p < 0.0001), higher fluoroscopy time (20 ±â€¯13 vs 16 ±â€¯9 min; p < 0.0001) and higher number of stents to treat the index lesion (2.2 ±â€¯0.5 vs 1; p < 0.0001). CONCLUSIONS: New designs of very long stents allow not only treating increasingly complex lesions, but also simplifying the procedure and decreasing the number of stents with very favorable results similar to those obtained with stent overlap.

Efficacy and Safety of Loading Doses With P2Y12-Receptor Antagonists in Patients Without Dual Antiplatelet Therapy Undergoing Elective Coronary Intervention.

BACKGROUND: European Guidelines on Myocardial Revascularization recommend clopidogrel loading dose added to acetylsalicylic acid in elective percutaneous coronary interventions (PCIs). However, there is few evidence supporting this recommendation and other P2Y12 inhibitors have not been tested in these patients. PURPOSE: To evaluate the effectiveness and safety of different loading doses of clopidogrel and ticagrelor in patients without double antiplatelet therapy and stable coronary artery disease (SCAD) undergoing elective PCI. METHODS: Retrospective study of 147 consecutive patients with SCAD undergoing elective PCI. Loading P2Y12 inhibitor doses evaluated were: clopidogrel 600 mg, clopidogrel 300 mg, clopidogrel 150 mg, and ticagrelor 180 mg. We analyzed the occurrence of major adverse cardiovascular events and periprocedural myocardial infarction. RESULTS: One hundred twenty-five patients were treated with clopidogrel (16 with clopidogrel 150 mg, 7 with clopidogrel 300 mg, and 93 with clopidogrel 600 mg) and 21 with ticagrelor 180 mg at the catheterization laboratory. The ticagrelor group had a significantly lower postprocedural peak of troponin-I (0.7 ± 3.4 vs. 0.3 ± 0.7 ng/mL; P = 0.02). There were no differences between groups in terms of major bleeding and hemoglobin drop after PCI (0.6 ± 0.8 vs. 4 ± 0.6; P = 0.8). The median of follow-up was 17 months (interquartile range 9-32.7). At the end of follow-up, major adverse cardiovascular event rate was not different between groups. CONCLUSIONS: In patients without dual antiplatelet therapy undergoing elective PCI, the use of ticagrelor showed lower postprocedural myocardial injury without more bleeding complications.

Valoración del tratamiento anticoagulante en pacientes diagnosticados de fibrilación auricular no valvular en una zona básica de salud / Assessment of anticoagulation treatments in non-valvular atrial fibrillation patients diagnosed in a basic health area

Introducción: La fibrilación auricular (FA) es la arritmia cardiaca más frecuente. En su manejo, es clave valorar la necesidad de anticoagulación. Nuestro objetivo fue valorar en pacientes diagnosticados de FA no valvular si la indicación de anticoagulación es adecuada en función de la escala CHA2DS2-VASc y la adecuación del rango del International Normalizad Ratio (INR) en los pacientes en tratamiento con antivitamina K. Métodos: Estudio observacional, analítico transversal. Se seleccionaron 232 pacientes con diagnóstico de FA no valvular. Se han analizado variables demográficas, variables de la escala CHA2DS2-VASc, tratamiento prescrito y valores de INR durante 6 meses consecutivos. La comparación de variables se realizó con ji cuadrado y la tendencia lineal entre grupos por Mantel Haenzel, siendo calculadas las odds ratios. Resultados: La prevalencia total de FA no valvular en el área fue 1,05%. El 88,4% presentó un CHA2DS2-VASc ≥ 2. Un 71,1% de pacientes con fibrilación auricular estaban anticoagulados, de los que el 58,2% tomaban fármacos antivitamina K. El 46,7% de los pacientes en tratamiento con acenocumarol presentó un INR con un tiempo en rango terapéutico directo insuficiente. La prescripción de antivitamina K en los pacientes con FA permanente fue superior que en pacientes con FA paroxística (62,8 vs. 37,2%, p<0,001). El consumo de fármacos que aumentan el sangrado se asoció a un peor control de INR (tras ajuste por las principales variables de relevancia clínica (odds ratio 2,17 [1,02-4,59], p=0,043). Conclusiones: El control de la anticoagulación oral con antivitamina K fue subóptimo pese a la adecuada adherencia de los pacientes. Los pacientes con FA paroxística recibieron menos antivitamina-K que los de FA persistente/permanente (AU)

Introduction: Atrial fibrillation (AF) is the most common cardiac arrhythmia. To assess the need for anticoagulation is essential for its management. Our objective was to investigate whether the indication of anticoagulation was adequate in patients diagnosed with non-valvular AF, given the CHA2-DS2-VASc scale, measuring the International Normalizad Ratio range (INR) in patients treated with anti-vitamin K drugs. Methods: This is an observational and cross sectional study. 232 patients with atrial fibrillation were included. We analyzed demographic, the CHA2-DS2-VASc and HAS-BLED variables, the treatment and INR values for 6 consequentive months. The confrontation of variables was performed using chi-square and Mantel-Haenzel test. Results: The prevalence of AF was 1.05%. The 88.4% had CHA2-DS2-VASc ≥ 2. The 71.1% were taking anticoagulants, of which 58.2% were under antivitamin k. The 46.7% of patients taking antivitamin K, presented inadequate range of INR. There was a greater prescription of antivitamin k in patients with persistent or permanent AF compared to the paroxysmal form (62.8 vs. 37.2% p<.001). The use of drugs that increase bleeding was associated with a worse control of INR after adjustment for the main variables of clinical relevance (odds ratio 2.17 [1.02-4.59], p=.043). Conclusions: The level of anticoagulation with antivitamin K was inadequate in our sample, despite a proper follow up and adherence to treatment. Patients with paroxysmal AF received less antivitamin K than those with persistent/permanent AF (AU)
