Resultados intrahospitalarios tras tratamiento percutáneo frente a quirúrgico en pacientes con estenosis aórtica y enfermedad arterial coronaria concomitante / In-hospital outcomes following percutaneous versus surgical intervention in the treatment of aortic stenosis and concomitant coronary artery disease

Introducción y objetivos: La enfermedad coronaria (EC) es frecuente en pacientes con estenosis aórtica; sin embargo, la estrategia terapéutica óptima sigue siendo objeto de debate. Investigamos los resultados periprocedimiento en pacientes sometidos a implante percutáneo de válvula aórtica con intervención coronaria percutánea (TAVI/ICP) frente al recambio valvular aórtico con injerto de derivación de arteria coronaria (RVAo/CABG) en pacientes con estenosis aórtica con EC.Métodos: Con los datos de alta del Sistema Nacional de Salud Español, se identificaron 6.194 pacientes (5.217 RVAo/CABG y 977 TAVI/ICP) entre 2016 y 2019. Se realizó un análisis emparejado por puntuación de propensión ajustado por características basales. El objetivo primario fue la mortalidad hospitalaria, Los objetivos secundarios fueron las complicaciones hospitalarias y rehospitalización cardiovascular a 30 días.Resultados: Tras el emparejamiento, se seleccionaron 774 parejas de pacientes. La mortalidad total hospitalaria fue más frecuente en el grupo quirúrgico (3,4 frente a 9,4%, p <0,001), al igual que el ictus periprocedimiento (0,9 frente a 2,2%, p=0,004), fallo renal agudo (4,3 frente a 16,0%, p <0,002), transfusión (9,6 frente a 21,1%, p <0,001) y neumonía intrahospitalaria (0,1 frente a 1,7%, p=0,001). La implantación de marcapasos permanente fue más frecuente en el tratamiento percutáneo (12,0 frente a 5,7%, p <0,001). Los centros de menor volumen (< 130 procedimientos por año) tuvieron mayor mortalidad hospitalaria para ambos procedimientos: TAVI/ICP (3,6 frente a 2,9%, p <0,001) y RVAo/CABG (9,3 frente a 6,8%, p <0,001). La rehospitalización cardiovascular a 30 días no difirió entre los grupos.(AU)

Introduction and objectives: Concomitant coronary artery disease (CAD) is prevalent among aortic stenosis patients; however the optimal therapeutic strategy remains debated. We investigated periprocedural outcomes among patients undergoing transcatheter aortic valve implantation with percutaneous coronary intervention (TAVI/PCI) vs surgical aortic valve replacement with coronary artery bypass grafting (SAVR/CABG) for aortic stenosis with CAD.Methods: Using discharge data from the Spanish National Health System, we identified 6194 patients (5217 SAVR/CABG and 977 TAVI/PCI) between 2016 and 2019. Propensity score matching was adjusted for baseline characteristics. The primary outcome was in-hospital all-cause mortality. Secondary outcomes were in-hospital complications and 30-day cardiovascular readmission.Results: Matching resulted in 774 pairs. In-hospital all-cause mortality was more common in the SAVR/CABG group (3.4% vs 9.4%, P <.001) as was periprocedural stroke (0.9% vs 2.2%; P=.004), acute kidney injury (4.3% vs 16.0%, P <.001), blood transfusion (9.6% vs 21.1%, P <.001), and hospital-acquired pneumonia (0.1% vs 1.7%, P=.001). Permanent pacemaker implantation was higher for matched TAVI/PCI (12.0% vs 5.7%, P <.001). Lower volume centers (< 130 procedures/y) had higher in-hospital all-cause mortality for both procedures: TAVI/PCI (3.6% vs 2.9%, P <.001) and SAVR/CABG (8.3 vs 6.8%, P <.001). Thirty-day cardiovascular readmission did not differ between groups.Conclusions: In this large contemporary nationwide study, percutaneous management of aortic stenosis and CAD with TAVI/PCI had lower in-hospital mortality and morbidity than surgical intervention. Higher volume centers had less in-hospital mortality in both groups. Dedicated national high-volume heart centers warrant further investigation.(AU)

Characteristics and in-hospital mortality of elderly patients with heart failure in Spanish hospitals.

BACKGROUND: The prevalence of heart failure (HF) increases with age, and it is one of the leading causes of hospitalization and death in older patients. However, there are little data on in-hospital mortality in patients with HF ≥ 75 years in Spain. METHODS: A retrospective analysis of the Spanish Minimum Basic Data Set was performed, including all HF episodes discharged from public hospitals in Spain between 2016 and 2019. Coding was performed using the International Classification of Diseases, 10th Revision. Patients ≥ 75 years with HF as the principal diagnosis were selected. We calculated: (1) the crude in-hospital mortality rate and its distribution according to age and sex; (2) the risk-standardized in-hospital mortality ratio; and (3) the association between in-hospital mortality and the availability of an intensive cardiac care unit (ICCU) in the hospital. RESULTS: We included 354,792 HF episodes of patients over 75 years. The mean age was 85.2 ± 5.5 years, and 59.2% of patients were women. The most frequent comorbidities were renal failure (46.1%), diabetes mellitus (35.5%), valvular disease (33.9%), cardiorespiratory failure (29.8%), and hypertension (26.9%). In-hospital mortality was 12.7%, and increased with age [odds ratio (OR) = 1.07, 95% CI: 1.07-1.07, P < 0.001] and was lower in women (OR = 0.96, 95% CI: 0.92-0.97, P < 0.001). The main predictors of mortality were the presence of cardiogenic shock (OR = 19.5, 95% CI: 16.8-22.7, P < 0.001), stroke (OR = 3.5, 95% CI: 3.0-4.0, P < 0.001) and advanced cancer (OR = 2.6, 95% CI: 2.5-2.8, P < 0.001). In hospitals with ICCU, the in-hospital risk-adjusted mortality tended to be lower (OR = 0.85, 95% CI: 0.72-1.00, P = 0.053). CONCLUSIONS: In-hospital mortality in patients with HF ≥ 75 years between 2016 and 2019 was 12.7%, higher in males and elderly patients. The main predictors of mortality were cardiogenic shock, stroke, and advanced cancer. There was a trend toward lower mortality in centers with an ICCU.

Impact of shock aetiology and hospital characteristics on the clinical profile, management and prognosis of patients with non ACS-related cardiogenic shock.

BACKGROUND: A significant proportion of cases of cardiogenic shock (CS) are due aetiologies other than acute coronary syndromes (non ACS-CS). We assessed differences regarding clinical profile, management, and prognosis according to the cause of CS among nonselected patients with CS from a large nationwide database. METHODS: We performed an observational study including patients admitted from the hospitals of the Spanish National Health System (SNHS) with a principal or secondary diagnosis code of CS (2016-2019). Data were obtained from the Minimum Basic Data Set (MBDS). Hospitals were classified according to the availability of cardiology related resources, as well as the availability of Intensive Cardiac Care Unit (ICCU). RESULTS: A total of 10,826 episodes of CS were included, of whom 5,495 (50.8%) were non-ACS related. Non ACS-CS patients were younger (71.5 vs. 72.4 years) and had a lower burden of arteriosclerosis-related comorbidities. Non ACS-CS cases underwent less often invasive procedures and presented lower in-hospital mortality (57.1% vs. 61%,p < 0.001). The most common main diagnosis among non ACS-CS was acute decompensation of chronic heart failure (ADCHF) (35.4%). A lower risk-adjusted in-hospital mortality rate was observed in high volume hospitals (52.6% vs. 56.7%; p < 0.001), as well as in centers with ICCU (OR: 0.71; CI 95%: 0.58-0.87; p < 0.001). CONCLUSIONS: More than a half of cases of CS were due to non-ACS causes. Non ACS-CS cases are a very heterogeneous group, with different clinical profile and management. Management at high-volume hospitals and availability of ICCU were associated with lower risk adjusted mortality among non ACS-CS patients.

Walnut Allergy Across Europe: Distribution of Allergen Sensitization Patterns and Prediction of Severity.

BACKGROUND: Walnut allergy is common across the globe, but data on the involvement of individual walnut components are scarce. OBJECTIVES: To identify geographical differences in walnut component sensitization across Europe, explore cosensitization and cross-reactivity, and assess associations of clinical and serological determinants with severity of walnut allergy. METHODS: As part of the EuroPrevall outpatient surveys in 12 European cities, standardized clinical evaluation was conducted in 531 individuals reporting symptoms to walnut, with sensitization to all known walnut components assessed in 202 subjects. Multivariable Lasso regression was applied to investigate predictors for walnut allergy severity. RESULTS: Birch-pollen-related walnut sensitization (Jug r 5) dominated in Northern and Central Europe and lipid transfer protein sensitization (Jug r 3) in Southern Europe. Profilin sensitization (Jug r 7) was prominent throughout Europe. Sensitization to storage proteins (Jug r 1, 2, 4, and 6) was detected in up to 10% of subjects. The walnut components that showed strong correlations with pollen and other foods differed between centers. The combination of determinants best predicting walnut allergy severity were symptoms upon skin contact with walnut, atopic dermatitis (ever), family history of atopic disease, mugwort pollen allergy, sensitization to cat or dog, positive skin prick test result to walnut, and IgE to Jug r 1, 5, 7, or carbohydrate determinants (area under the curve = 0.81; 95% CI, 0.73-0.89). CONCLUSIONS: Walnut-allergic subjects across Europe show clear geographical differences in walnut component sensitization and cosensitization patterns. A predictive model combining results from component-based serology testing with results from extract-based testing and information on clinical background allows for good discrimination between mild to moderate and severe walnut allergy.

Valor pronóstico de la primera glucemia en ayunas en comparación con la glucemia al ingreso en pacientes con síndrome coronario agudo / Prognostic Value of First Fasting Glucose Measurement Compared With Admission Glucose Level in Patients With Acute Coronary Syndrome

Introducción y objetivos. La glucemia al ingreso (GI) es un factor pronóstico conocido en el síndrome coronario agudo (SCA), pero hay poca información acerca del valor de la primera glucemia en ayunas (PGA). Este estudio analiza el valor pronóstico de la PGA en pacientes con SCA comparado con el de la GI. Métodos. Se analizó a los 547 pacientes que ingresaron consecutivamente en nuestro centro con el diagnóstico de SCA en el año 2006. Las cifras de GI y PGA fueron estratificadas en tres niveles (< 126, 126-200 y > 200 mg/dl). El objetivo primario del estudio fue el evento combinado de muerte y/o reinfarto durante la hospitalización. Resultados. El desenlace principal ocurrió en 46 pacientes (25 muertes). Los pacientes de este grupo eran de mayor edad, más frecuentemente diabéticos, fumadores, con infarto de miocardio previo, con superior clase Killip durante el ingreso, con afección de más de un vaso en la coronariografía, con menor fracción de eyección y mayores creatinina al ingreso, GI y PGA. En el análisis multivariable ajustado por las variables anteriores, la PGA se mostró como predictor independiente de muerte y/o reinfarto (126-200 mg/dl, odds ratio [OR] = 5,26; intervalo de confianza [IC] del 95%, 1,09-25,45; > 200 mg/dl, OR = 6,66; IC del 95%, 2,05-21,63), no así la GI (126-200 mg/dl, OR = 0,84; IC del 95%, 0,63-1,05; > 200 mg/dl, OR = 1,14; IC del 95%, 0,29-4,51). Conclusiones. La PGA se mostró mejor predictor de eventos adversos (muerte y/o reinfarto) que la GI en pacientes con SCA durante la hospitalización (AU)

Introduction and objectives. The admission plasma glucose (APG) level is a recognized prognostic factor in patients with acute coronary syndrome (ACS). However, little is known about the prognostic value of the first fasting plasma glucose (FPG) measurement. The aim of this study was to determine the prognostic value of the first FPG measurement relative to that of the APG level in patients with ACS. Methods. The study involved 547 consecutive patients who were admitted to our center with a diagnosis of ACS in 2006. Patients were divided into three groups according to their first FPG or APG level (i.e., <126 mg/dL, 126­200 mg/dL, or >200 mg/dL). The primary endpoint was the combined outcome of death or reinfarction during hospitalization. Results. The primary endpoint was observed in 46 patients, 25 of whom died. Patients in this group were older, were more often diabetics or smokers, more often had had a prior myocardial infarction, were in a higher admission Killip class, showed more than one vessel disease on catheterization, had a lower left ventricular ejection fraction, and had higher admission creatinine, APG, and first FPG levels. Multivariate analysis, adjusted for previously identified factors, revealed that the first FPG level was an independent risk factor for death or reinfarction (126­200 mg/dL, odds ratio [OR]=5.26; 95% confidence interval [CI], 1.09­25.45; >200 mg/dL, OR=6.66; 95% CI, 2.05­21.63), but that the APG level was not (126­200 mg/dL, OR=0.84; 95% CI, 0.63­1.05; >200 mg/dL, OR=1.14; 95% CI, 0.29­4.51). Conclusions. The first FPG level was found to be a better predictor of an adverse outcome (i.e., death or reinfarction) during hospitalization in ACS patients than the APG level (AU)
