Impact of valvular surgery according to frailty risk in patients with infective endocarditis.

BACKGROUND: Observational studies suggest that valvular surgery can reduce mortality in selected patients with infective endocarditis (IE). However, the benefit of this intervention according to frailty levels remains unclear. Our study aims to assess the effect of valvular surgery according to frailty status in this population. METHODS: We performed a retrospective study using the 2016-2019 National Inpatient Sample database. Adult patients with a primary diagnosis of IE were included. Frailty was assessed using the Hospital Frailty Risk Score. Inverse probability of treatment weighting (IPTW) was used to balance baseline differences between groups. RESULTS: A total of 53,275 patients with IE were included, with 18.3% underwent valvular surgery. The median age was 52 (34-68) years, with 41% females. Overall, 42.7% had low risk of frailty, 53.1% intermediate risk, and 4.2% high risk. After IPTW adjustment, in-hospital mortality was similar both for the entire cohort between valvular and non-valvular surgery groups (3.7% vs. 4.1%, p = .483), and low (1% vs. 0.9%, p = .952) or moderate (5.4% vs. 6%, p = .548) risk of frailty. However, patients at high risk of frailty had significantly lower in-hospital mortality in the valvular surgery group (4.6% vs. 13.9%, p = .016). Renal replacement therapy was similar between groups across frailty status. In contrast, surgery was associated with increased use of mechanical circulatory support and pacemaker implantation. CONCLUSIONS: Our findings suggest that there was no difference in survival between valve surgery and medical management in patients at low/intermediate frailty risk, but not for high-risk individuals.

EFFECT OF PULMONARY ARTERY CATHETERIZATION IN PATIENTS WITH NONISCHEMIC CARDIOGENIC SHOCK: A NATIONWIDE ANALYSIS.

ABSTRACT: Background: Pulmonary artery catheterization (PAC) has been widely used in critically ill patients, yielding mixed results. Prior studies on cardiogenic shock (CS) predominantly included patients with acute myocardial infarction. This study aims to examine the effect of PAC use in patients with nonischemic CS. Methods: This retrospective cohort study employed data from the National Inpatient Sample database, including weighted hospitalizations of adult patients with nonischemic CS during 2017 to 2019. In-hospital outcomes were compared between groups using inverse probability of treatment weighting. Results: A total of 303,970 patients with nonischemic CS were included, of whom 17.5% received a PAC during their hospitalization. The median age was 67 years (interquartile range: 57-77) and 61% were male. After inverse probability of treatment weighting, patients in the PAC group had significantly lower in-hospital mortality (24.8% vs. 35.3%, P < 0.001), renal replacement therapy (10.7% vs. 12.4%, P = 0.002), in-hospital cardiac arrest (7.1% vs. 9.6%, P < 0.001), and mechanical ventilation (44.6% vs. 50.4%, P < 0.001) compared to non-PAC group. In contrast, the PAC group had higher use of intra-aortic balloon pump (15.4% vs. 3.4%, P < 0.001), percutaneous ventricular assist devices (12.6% vs. 2.6%, P < 0.001), extracorporeal membrane oxygenation (3.9% vs. 2.5%, P < 0.001), and heart transplantation (2.1% vs. 0.4%, P < 0.001). Conclusion: In the real-world setting, invasive hemodynamic monitoring with PAC in patients with nonischemic CS is associated with survival benefits and a reduction in adverse events, including reduced need for renal replacement therapy, mechanical ventilation and risk of in-hospital cardiac arrest.

Pregnancy, Reproductive Factors, and Female Heart Failure Risk and Outcomes.

PURPOSE OF REVIEW: The purpose of this review is to provide an overview of recent evidence on female-specific risk factors related to reproductive status or pregnancy. RECENT FINDINGS: Pregnancy-related factors, including hypertensive disorders and gestational diabetes, increase the risk of heart failure in women, while breastfeeding and hormone therapy may offer protection. Hypertensive disorders of pregnancy, gestational diabetes, polycystic ovarian syndrome, placental abruption, younger maternal age at first live birth, younger maternal age at last live birth, number of stillbirths, number of pregnancies, onset of menstruation before 12 years of age, shorter reproductive age, ovariectomy, and prolonged absence of ovarian hormones may increase the risk of heart failure in women. Conversely, breastfeeding status and hormone therapy (for menopause or contraception) may serve as protective factors, while fertility treatments have no discernible effect on the risk of heart failure.

Sex differences in population versus in-hospital use of aortic valve replacement procedures in Spain.

BACKGROUND AND AIMS: It is not well known if sex differences in the use and results of aortic valve replacement (AVR) are changing. The aim of the study is to assess the time trends in the differences by sex in the utilisation of AVR procedures in hospitals and in the community. METHODS: Retrospective observational analysis using data from the Spanish National Hospitalizations Administrative Database. All hospitalisations between 2016 and 2021 with a main diagnosis of aortic stenosis (ICD-10 codes: I35.0 and I35.2) were included. Time trends in hospitalisation, AVRs and hospital outcomes were analysed. Crude utilisation and population-standardised rates were calculated. RESULTS: During the study period, 64 384 hospitalisations in 55 983 patients (55.5% men) with 36 915 (65,9%) AVR were recorded. Of these, 15 563 (42.2%) were transcatheter and 21 432 (58.0%) surgical. At hospital level, transcatheter procedures were more frequently performed in women (32.3% vs 24.2%, p < 0.001) and surgical in men (42.9% vs. 32.5%, p < 0.001) but at the population level, surgical and transcatheter aortic valve replacements were used more frequently in men (12.6 surgical and 8.0 transcatheter per 100 000 population) vs women (6.4 and 5.8, respectively; p < 0.001 for both comparisons). Transcatheter procedures shifted from 17.3% in 2016 to 38.0% in 2021, overtaking surgical procedures in 2018 for women and 2021 for men. CONCLUSIONS: TAVR has displaced SAVR as the most frequent AVR procedure in Spain by 2020. This occurred earlier in women, who despite the greater weight of their age group in the older population, receive fewer AVRs, both SAVR and TAVR.

Impacto de la fracción de eyección del ventrículo izquierdo en el consumo de recursos, los costes y el pronóstico en pacientes con insuficiencia cardiaca / Differences in clinical outcomes, health care resource utilization and costs in heart failure patients according to left ventricular ejection fraction

Introducción y objetivos: No se conoce bien el impacto de la fracción de eyección del ventrículo izquierdo (FEVI) en el coste y la utilización de recursos sanitarios (URS) en la insuficiencia cardiaca (IC). El objetivo de nuestro trabajo es comparar el consumo de costes, la URS y el pronóstico según grupos de FEVI. Métodos: Estudio observacional retrospectivo que incluyó a todos los pacientes con diagnóstico principal de IC en urgencias o en una hospitalización en un centro terciario español durante 2018. Se excluyó la IC de nuevo diagnóstico. Se compararon los resultados clínicos, los costes y la URS según la FEVI (reducida [IC-FEr], ligeramente reducida [IC-FElr] y conservada [IC-FEc]) a 1 año. Resultados: De 1.287 pacientes con diagnóstico de IC en urgencias, 365 (28,4%) fueron dados de alta (grupo de urgencias [GU]) y 919 (71,4%), hospitalizados (GH). En total, 190 pacientes (14,7%) tenían IC-FEr; 146 (11,4%), IC-FElr y 951 (73,9%), IC-FEc. La media de edad fue 80,1±10,7 años, y el 57,1% eran mujeres. La mediana [intervalo intercuartílico] del coste por paciente-año fue de 1.889 [259-6.269] euros en el GU y 5.008 [2.747-9.589] euros en el GH (p <0,001). Los pacientes con IC-FEr del GU sufrieron más hospitalizaciones. El coste de la IC-FEr por paciente-año fue superior en ambos grupos: en el GU, 4.763 [2.076-17.155] euros con IC-FEr frente a 3.900 [590-8.013] euros con IC-FElr frente a 3.812 [259-5.486] euros con IC-FEc; en el GH, 6.321 [3.335-796] frente a 6.170 [3.189-10.484] frente a 4.636 [2.609-8.977] euros respectivamente; todos, p <0,001). Esta diferencia se debió a que los pacientes con IC-FEr ingresaron con mayor frecuencia en unidades de cuidados críticos y recibieron más pruebas diagnóstico-terapéuticas. Conclusiones: La FEVI influye significativamente en los costes y URS en la IC. Los pacientes con IC-FEr, especialmente los hospitalizados, concentran un mayor coste que aquellos con IC-FEc.(AU)

Introduction and objectives: The impact of left ventricular ejection fraction (LVEF) on health care resource utilization (HCRU) and cost in heart failure (HF) patients is not well known. We aimed to compare outcomes, HCRUs and costs according to LVEF groups. Methods: Retrospective, observational study of all patients with an emergency department (ED) visit or admission to a tertiary hospital in Spain 2018 with a primary HF diagnosis. We excluded patients with newly diagnosed heart failure. One-year clinical outcomes, costs and HCRUs were compared according to LVEF (reduced [HFrEF], mildly reduced [HFmrEF], and preserved [HFpEF]). Results: Among 1287 patients with a primary diagnosis of HF in the ED, 365 (28.4%) were discharged to home (ED group), and 919 (71.4%) were hospitalized (hospital group [HG]). In total, 190 patients (14.7%) had HFrEF, 146 (11.4%) HFmrEF, and 951 (73.9%) HFpEF. The mean age was 80.1±10.7 years; 57.1% were female. The median [interquartile range] of costs per patient/y was €1889 [259-6269] in the ED group and €5008 [2747-9589] in the HG (P <.001). Hospitalization rates were higher in patients with HFrEF in the ED group. The median costs of HFrEF per patient/y were higher in patients in both groups: €4763 [2076-17 155] vs €3900 [590-8013] for HFmrEF vs €3812 [259-5486] for HFpEF in the ED group, and €6321 [3335-796] vs €6170 [3189-10484] vs €4636 [2609-8977], respectively, in the hospital group (all P <.001). This difference was driven by the more frequent admission to intensive care units, and greater use of diagnostic and therapeutic tests among HFrEF patients. Conclusions: In HF, LVEF significantly impacts costs and HCRU. Costs were higher in patients with HFrEF, especially those requiring hospitalization, than in those with HFpEF.(AU)

Echocardiographic Criteria to Differentiate Constrictive Pericarditis From Restrictive Cardiomyopathy: A Meta-analysis.

Background: To assess the diagnostic accuracy of the Mayo Clinic echocardiographic criteria for differentiating between constrictive pericarditis and restrictive cardiomyopathy. Methods: We searched electronic databases for the date range from their inception to July 1, 2022. The index tests were the Mayo Clinic echocardiographic criteria. We performed a bivariate random-effects model to estimate the pooled sensitivity and specificity, each with 95% confidence interval (CI). The area under the curve of the summary receiver operator characteristic curves, with 95% CI, was also calculated. Results: We included 17 case-control studies involving 889 patients. The pooled sensitivity and specificity (95% CI), respectively, were as follows: ventricular septal shift, 82% (60%-94%) and 78% (65%-87%); respiratory variation in mitral inflow ≥ 14.6%, 71% (51%-85%) and 82% (66%-91%); septal e' velocity ≥ 8 cm/s, 83% (80%-87%) and 90% (83%-95%); septal e' velocity/lateral e' velocity ≥ 0.88, 74% (64%-82%) and 81% (70%-88%); and hepatic vein ratio in expiration ≥ 0.79, 73% (65%-81%) and 71% (19%-96%). The area under the curve of the summary receiver operator characteristic curves varied from 0.75 to 0.85, with overlapping CIs across index tests. Conclusions: Our meta-analysis suggests that all echocardiographic parameters from the Mayo Clinic criteria have good diagnostic accuracy for differentiating between constrictive pericarditis and restrictive cardiomyopathy.

Contexte: Évaluation de l'exactitude diagnostique des critères échocardiographiques de la clinique Mayo visant à faire la distinction entre une péricardite constrictive et une cardiomyopathie restrictive. Méthodologie: Nous avons effectué une recherche dans des bases de données électroniques pour la période s'étendant de leur date de création au 1er juillet 2022. Les tests de concordance portaient sur les critères échocardiographiques de la clinique Mayo. Nous avons réalisé un modèle à effets aléatoires et à deux variables afin d'estimer la sensibilité et la spécificité en fonction des données regroupées, chacune avec un intervalle de confiance (IC) à 95 %. L'aire sous la courbe des courbes caractéristiques sommaires de la performance du test, avec un IC à 95 %, a également été calculée. Résultats: Nous avons inclus 17 études cas-témoins comptant 889 patients. Selon les données groupées, la sensibilité et la spécificité (IC à 95 %), respectivement, étaient les suivantes : déplacement du septum interventriculaire, 82 % (60 à 94 %) et 78 % (65 à 87 %); variation respiratoire lors du remplissage mitral ≥ 14,6 %, 71 % (51 à 85 %) et 82 % (66 à 91 %); vitesse eʹ mesurée en septal ≥ 8 cm/s, 83 % (80 à 87 %) et 90 % (83 à 95 %); rapport vitesse eʹ mesurée en septal/vitesse eʹ mesurée en latéral ≥ 0,88, 74 % (64 à 82 %) et 81 % (70 à 88 %); et rapport veineux hépatique lors de l'expiration ≥ 0,79, 73 % (65 à 81 %) et 71 % (19 à 96 %). L'aire sous la courbe des courbes caractéristiques sommaires de la performance du test variait de 0,75 à 0,85, avec des IC se chevauchant dans les tests de concordance. Conclusions: Notre méta-analyse laisse entendre que tous les paramètres échocardiographiques de la clinique Mayo ont une bonne exactitude diagnostique pour faire la distinction entre la péricardite constrictive et la cardiomyopathie restrictive.

Sex differences in patterns of referral and resource utilization in the cardiology clinic: an outpatient analysis.

Aims: Women may have different management patterns than men in specialised care. Our aim was to assess potential sex differences in referral, management and outcomes of patients attending outpatient cardiac consultations. Methods and results: Retrospective observational analysis of patients ≥18 years referred for the first time from primary care to a tertiary hospital cardiology clinic in 2017-2018, comparing reasons for referral, decisions and post-visit outcomes by sex.A total of 5,974 patients, 2,452 (41.0%) men aged 59.2 ± 18.6 years and 3,522 (59.0%) women aged 64.5 ± 17.9 years (P < 0.001) were referred for a first cardiology consultation. The age-related referral rates were higher in women. The most common reasons for consultation were palpitations in women (n = 676; 19.2%) and ECG abnormalities in men (n = 570; 23.2%). Delays to cardiology visits and additional tests were similar. During 24 months of follow-up, women had fewer cardiology hospitalisations (204; 5.8% vs. 229; 9.3%; P = 0.003) and lower mortality (65; 1.8% vs. 66; 2.7%; P = 0.028), but those aged <65 years had more emergency department visits (756; 48.5% vs. 560; 39.9%, P < 0.001) than men. Conclusion: There are substantial sex differences in primary care cardiology referral patterns, including causes, rates, decisions and outcomes, which are only partially explained by age differences. Further research is needed to understand the reasons for these differences.

Prognostic Implications of High-Degree Atrio-Ventricular Block in Patients with Acute Myocardial Infarction in the Contemporary Era.

BACKGROUND: High-degree atrioventricular block (HAVB) is a known complication of ST-segment elevation myocardial infarction (STEMI). We aimed to determine the prevalence and prognostic impact of HAVB in a contemporary cohort of STEMI. METHODS: Data were collected from the DIAMANTE registry that included STEMI patients admitted to our cardiac intensive care unit treated with urgent reperfusion. We studied the clinical characteristics and evolution in patients with and without HAVB at admission. RESULTS: From 1109 consecutive patients, HAVB was documented in 95 (8.6%). The right coronary artery was the culprit vessel in 84 patients with HAVB (88.4%). The independent predictors of HAVB were: male sex (OR 1.9, 95% CI 1.2-2.9), age (OR 1.03, 95% CI 1.01-1.05), involvement of right coronary artery (OR 12.4, 95% CI 7.6-20.2), and creatinine value (OR 1.5, 95% CI 1.1-2.0). A transient percutaneous pacemaker was used in 37 patients with HAVB (38.9%). Patients with HAVB had higher mortality that patients without HAVB (15.8% vs. 4.1%, p < 0.001); however, in multivariate analysis, HAVB was not an independent predictor of in-hospital mortality. CONCLUSIONS: HAVB was seen in 9% of STEMI patients and was particularly frequent in elderly males with renal failure. Patients with HAVB had a poor prognosis during hospitalization, but HAVB was not an independent predictor of in-hospital mortality.

The added value of hypertonic saline solution to furosemide monotherapy in patients with acute decompensated heart failure: A meta-analysis and trial sequential analysis.

We assessed the effects of hypertonic saline solution (HSS) plus furosemide versus furosemide alone in patients with acute decompensated heart failure (ADHF). We searched four electronic databases for randomized controlled trials (RCTs) until June 30, 2022. The quality of evidence (QoE) was assessed using the GRADE approach. All meta-analyses were performed using a random-effects model. A trial sequential analysis (TSA) was also conducted for intermediate and biomarker outcomes. Ten RCTs involving 3013 patients were included. HSS plus furosemide significantly reduced the length of hospital stay (mean difference [MD]: -3.60 days; 95% confidence interval [CI]: -4.56 to -2.64; QoE: moderate), weight (MD: -2.34 kg; 95% CI: -3.15 to -1.53; QoE: moderate), serum creatinine (MD: -0.41 mg/dL; 95% CI: -0.49 to -0.33; QoE: low), and type-B natriuretic peptide (MD: -124.26 pg/mL; 95% CI: -207.97 to -40.54; QoE: low) compared to furosemide alone. HSS plus furosemide significantly increased urine output (MD: 528.57 mL/24 h; 95% CI: 431.90 to 625.23; QoE: moderate), serum Na+ (MD: 6.80 mmol/L; 95% CI: 4.92 to 8.69; QoE: low), and urine Na+ (MD: 54.85 mmol/24 h; 95% CI: 46.31 to 63.38; QoE: moderate) compared to furosemide alone. TSA confirmed the benefit of HSS plus furosemide. Due to the heterogeneity in mortality and heart failure readmission, meta-analysis was not performed. Our study shows that HSS plus furosemide, compared to furosemide alone, improved surrogated outcomes in ADHF patients with low or intermediate QoE. Adequately powered RCTs are still needed to assess the benefit on heart failure readmission and mortality.

Differences in clinical outcomes, health care resource utilization and costs in heart failure patients according to left ventricular ejection fraction.

INTRODUCTION AND OBJECTIVES: The impact of left ventricular ejection fraction (LVEF) on health care resource utilization (HCRU) and cost in heart failure (HF) patients is not well known. We aimed to compare outcomes, HCRUs and costs according to LVEF groups. METHODS: Retrospective, observational study of all patients with an emergency department (ED) visit or admission to a tertiary hospital in Spain 2018 with a primary HF diagnosis. We excluded patients with newly diagnosed heart failure. One-year clinical outcomes, costs and HCRUs were compared according to LVEF (reduced [HFrEF], mildly reduced [HFmrEF], and preserved [HFpEF]). RESULTS: Among 1287 patients with a primary diagnosis of HF in the ED, 365 (28.4%) were discharged to home (ED group), and 919 (71.4%) were hospitalized (hospital group [HG]). In total, 190 patients (14.7%) had HFrEF, 146 (11.4%) HFmrEF, and 951 (73.9%) HFpEF. The mean age was 80.1±10.7 years; 57.1% were female. The median [interquartile range] of costs per patient/y was €1889 [259-6269] in the ED group and €5008 [2747-9589] in the HG (P <.001). Hospitalization rates were higher in patients with HFrEF in the ED group. The median costs of HFrEF per patient/y were higher in patients in both groups: €4763 [2076-17 155] vs €3900 [590-8013] for HFmrEF vs €3812 [259-5486] for HFpEF in the ED group, and €6321 [3335-796] vs €6170 [3189-10484] vs €4636 [2609-8977], respectively, in the hospital group (all P <.001). This difference was driven by the more frequent admission to intensive care units, and greater use of diagnostic and therapeutic tests among HFrEF patients. CONCLUSIONS: In HF, LVEF significantly impacts costs and HCRU. Costs were higher in patients with HFrEF, especially those requiring hospitalization, than in those with HFpEF.

Coronary Artery Disease and Prognosis of Heart Failure with Reduced Ejection Fraction.

Our aim was to determine the prognostic impact of coronary artery disease (CAD) on heart failure with reduced ejection fraction (HFrEF) mortality and readmissions. From a prospective multicenter registry that included 1831 patients hospitalized due to heart failure, 583 had a left ventricular ejection fraction of <40%. In total, 266 patients (45.6%) had coronary artery disease as main etiology and 137 (23.5%) had idiopathic dilated cardiomyopathy (DCM), and they are the focus of this study. Significant differences were found in Charlson index (CAD 4.4 ± 2.8, idiopathic DCM 2.9 ± 2.4, p < 0.001), and in the number of previous hospitalizations (1.1 ± 1, 0.8 ± 1.2, respectively, p = 0.015). One-year mortality was similar in the two groups: idiopathic DCM (hazard ratio [HR] = 1), CAD (HR 1.50; 95% CI 0.83-2.70, p = 0.182). Mortality/readmissions were also comparable: CAD (HR 0.96; 95% CI 0.64-1.41, p = 0.81). Patients with idiopathic DCM had a higher probability of receiving a heart transplant than those with CAD (HR 4.6; 95% CI 1.4-13.4, p = 0.012). The prognosis of HFrEF is similar in patients with CAD etiology and in those with idiopathic DCM. Patients with idiopathic DCM were more prone to receive heart transplant.

Sex differences in temporal trends in main and secondary pulmonary embolism diagnosis and case fatality rates: 2003-2019.

AIMS: There is controversy regarding the incidence and outcomes of pulmonary embolism (PE) according to sex. Our aim was to address sex differences in temporal trends in main and secondary hospital PE diagnoses, management and case fatality rates (CFR). METHODS AND RESULTS: Retrospective analysis of Spain´s National Healthcare System hospital database, years 2003-2019, for patients ≥18 years with main or secondary PE diagnosis. Trends by sex in hospital diagnosis, use of procedures, and CFRs were analysed by joinpoint and Poisson regression models. Of 339 469 PE diagnoses, 52% were in women. Sixty-five percent were main diagnosis, 35.2% secondary. Total annual diagnoses and frequentation rates increased similarly in men and women: average annual percent change (AAPC): 2.0% (95% CI, 1.3-2.6; P < 0.005). Secondary PEs were more common in men (37.8% vs. 32.9%, P < 0.001). Men showed greater comorbidity than women (Charlson index 2.22 ± 0.01 vs. 1.74 ± 0.01, P < 0.001), particularly cancer in the secondary diagnosis group (40.9% vs. 31.6%, P < 0.001). CFRs for PE as main diagnosis were comparable and decreased in parallel in men (from 13.8% in 2003 to 7.3% in 2019) and women (from 13.1% in 2003 to 6.9% in 2019). However, for PE as secondary diagnosis, CFRs remained higher (P < 0.001) in men (from 42.5% in 2003 to 26.2% in 2019) than women (from 34.4% in 2003 to 22.8% in 2019). CONCLUSION: PE hospital diagnosis increased significantly between 2003 and 2019 in men and women for both main and secondary diagnosis. Although in-hospital CFR decreased one third still remains very high, especially in men with secondary PE diagnosis.

Epidemiología de las enfermedades valvulares aórticas no reumáticas en España, 2003-2018 / Time trends in the epidemiology of nonrheumatic aortic valve disease in Spain, 2003-2018

Introducción y objetivos: El impacto de las mejoras terapéuticas en las enfermedades valvulares aórticas no reumáticas (EVANR) se ha evaluado a nivel individual, pero no en la población hospitalizada. El objetivo del estudio es evaluar la evolución de las tasas de ingreso, tratamiento y letalidad en pacientes hospitalizados con EVANR como diagnóstico principal o secundario. Métodos: Análisis retrospectivo de los pacientes hospitalizados con EVANR entre 2003 y 2018 en España a partir del Conjunto Mínimo Básico de Datos. Se evaluó la evolución de las tasas estandarizadas por edad y sexo de hospitalización y utilización de procedimientos, características basales y letalidad por tipo de diagnóstico mediante regresión de Poisson y análisis de Joinpoint. Resultados:b Las hospitalizaciones por EVANR aumentaron de 69.213 en 2003 a 136.185 en 2018. La letalidad cruda aumentó del 6,7% al 8,7% (IRR, 1,015; IC95%, 1,012-1,018; p <0,001). La letalidad estandarizada disminuyó en los pacientes con diagnóstico principal (5,5 a 3,5%; IRR, 0,953; IC95%, 0,942-0,964), pero aumentó en aquellos con diagnóstico secundario (8,0 a 8,8%; IRR, 1,005; IC95%, 1,002-1,009). Las sustituciones valvulares aórticas aumentaron de 10,5 a 17,1 procedimientos por 100.000 habitantes (IRR, 1,033; IC95%, 1,030-1,037), principalmente los procedimientos transcatéter (IRR, 1,345; IC95%, 1,302-1,389). Conclusiones: Las hospitalizaciones de pacientes con EVANR están aumentando, sobre todo como diagnóstico secundario. El uso de la sustitución de válvula aórtica está aumentando en paralelo con una disminución de la letalidad posprocedimiento, pero únicamente en los pacientes con diagnóstico principal de EVANR.(AU)

Introduction and objectives: The impact of therapeutic improvements in nonrheumatic aortic valve disease (NRAVD) has been assessed at the patient level but not in the whole population with the disease. Our objective was to assess temporal trends in hospitalization rates, treatment and fatality rates in patients with a main or secondary NRAVD diagnosis. Methods: Retrospective analysis of administrative claims from patients hospitalized with a main or secondary NRAVD diagnosis between 2003 and 2018 in Spain. Time trends in age- and sex-standardized hospitalization and procedure rates, baseline characteristics and case fatality rates by diagnosis type were assessed by Poisson regression and joinpoint analysis. Results: Hospital admissions in patients with NRAVD increased from 69 213 in 2003 to 136 185 in 2018. The crude in-hospital fatality rate increased from 6.7% to 8.7% (IRR, 1.015; 95%CI, 1.012-1.018; P <.001) without changes after adjustment. Adjusted fatality rates decreased in patients with a main NRAVD diagnosis (5.5% to 3.5%; IRR, 0.953; 95%CI, 0.942-0.964) but increased in those with a secondary diagnosis (8.0% to 8.8%; IRR, 1.005; 95%CI, 1.002-1.009). Aortic valve replacements increased from 10.5 to 17.1 procedures per 100 000 population (IRR, 1.033; 95%CI, 1.030-1.037), mainly driven by transcatheter procedures (IRR, 1.345; 95%CI, 1.302-1.389). Conclusions: Hospitalizations in patients with NRAVD are increasing, with most being secondary diagnoses. The use of aortic valve replacement is increasing with a reduction in fatality rates but only in patients with a main diagnosis.(AU)

Pediatric Infective Endocarditis: A Literature Review.

Infective endocarditis in children is a rare entity that poses multiple challenges. A history of congenital heart disease is the most common risk factor, although in recent years, other emerging predisposing conditions have gained relevance, such as central venous catheters carriers or children with chronic debilitating conditions; cases in previously healthy children with no medical history are also seen. Diagnosis is complex, although it has improved with the use of multimodal imaging techniques. Antibiotic treatment should be started early, according to causative microorganism and risk factors. Complications are frequent and continue to cause significant morbidity. Most studies have been conducted in adults and have been generalized to the pediatric population, with subsequent limitations. Our manuscript presents a comprehensive review of pediatric infective endocarditis, including recent advances in diagnosis and management.

Time trends in the epidemiology of nonrheumatic aortic valve disease in Spain, 2003-2018.

INTRODUCTION AND OBJECTIVES: The impact of therapeutic improvements in nonrheumatic aortic valve disease (NRAVD) has been assessed at the patient level but not in the whole population with the disease. Our objective was to assess temporal trends in hospitalization rates, treatment and fatality rates in patients with a main or secondary NRAVD diagnosis. METHODS: Retrospective analysis of administrative claims from patients hospitalized with a main or secondary NRAVD diagnosis between 2003 and 2018 in Spain. Time trends in age- and sex-standardized hospitalization and procedure rates, baseline characteristics and case fatality rates by diagnosis type were assessed by Poisson regression and joinpoint analysis. RESULTS: Hospital admissions in patients with NRAVD increased from 69 213 in 2003 to 136 185 in 2018. The crude in-hospital fatality rate increased from 6.7% to 8.7% (IRR, 1.015; 95%CI, 1.012-1.018; P <.001) without changes after adjustment. Adjusted fatality rates decreased in patients with a main NRAVD diagnosis (5.5% to 3.5%; IRR, 0.953; 95%CI, 0.942-0.964) but increased in those with a secondary diagnosis (8.0% to 8.8%; IRR, 1.005; 95%CI, 1.002-1.009). Aortic valve replacements increased from 10.5 to 17.1 procedures per 100 000 population (IRR, 1.033; 95%CI, 1.030-1.037), mainly driven by transcatheter procedures (IRR, 1.345; 95%CI, 1.302-1.389). CONCLUSIONS: Hospitalizations in patients with NRAVD are increasing, with most being secondary diagnoses. The use of aortic valve replacement is increasing with a reduction in fatality rates but only in patients with a main diagnosis.

Early vs. Delayed Initiation of Treatment With P2Y12 Inhibitors in Patients With Non-ST-Segment Elevation Acute Coronary Syndrome: A Systematic Review and Network Meta-Analysis of Randomized Controlled Trials.

Aims: Whether early or delayed dual antiplatelet therapy initiation is better in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) is unclear. We assessed the evidence for comparing the efficacy and safety of early vs. delayed P2Y12 inhibitor initiation in NSTE-ACS. Methods: The randomized controlled trials with available comparisons between early and delayed initiation of P2Y12 inhibitors (clopidogrel, prasugrel, and ticagrelor) in patients with NSTE-ACS until January 2021 were reviewed. The primary outcomes were trial-defined major adverse cardiovascular events (MACEs) and bleeding. Secondary outcomes were all-cause mortality, cardiovascular mortality, myocardial infarction, stent thrombosis, urgent coronary revascularization, and stroke. Frequentist random-effects network meta-analyses were conducted, ranking best treatments per outcome with p-scores. Results: A total of nine trials with intervention arms including early and delayed initiation of clopidogrel (n = 5), prasugrel (n = 8), or ticagrelor (n = 6) involving 40,096 patients were included. Early prasugrel (hazard ratio [HR], 0.59; 95% confidence interval [95%CI], 0.40-0.87), delayed prasugrel (HR, 0.60; 95%CI 0.43-0.84), and early ticagrelor (HR, 0.84; 95%CI, 0.74-0.96) significantly reduced MACE compared with early clopidogrel, but increased bleeding risk. Delayed prasugrel ranked as the best treatment to reduce MACE (p-score=0.80), early prasugrel to reduce all-cause mortality, cardiovascular mortality, stent thrombosis, and stroke, and delayed clopidogrel to reduce bleeding (p-score = 0.84). The risk of bias was low for all trials. Conclusion: In patients with NSTE-ACS, delayed prasugrel initiation was the most effective strategy to reduce MACE. Although early prasugrel was the best option to reduce most secondary cardiovascular outcomes, it was associated with the highest bleeding risk. The opposite was found for delayed clopidogrel.

Primary vs. Secondary Heart Failure Diagnosis: Differences in Clinical Outcomes, Healthcare Resource Utilization and Cost.

Background: There is scarce information on patients with secondary heart failure diagnosis (sHF). We aimed to compare the characteristics, burden, and outcomes of sHF with those with primary HF diagnosis (pHF). Methods: Retrospective, observational study on patients ≥18 years with emergency department (ED) visits during 2018 with pHF and sHF in ED or hospital (ICD-10-CM) diagnostic codes. Baseline characteristics, 30-day and 1-year mortality, readmission and re-ED visit rates, and costs were compared between sHF and pHF. Results: Out of the 797 patients discharged home from the ED, 45.5% had sHF, and these presented lower 1-year hospitalization, re-ED visit rates, and costs. In contrast, out of the 2,286 hospitalized patients, 55% had sHF and 45% pHF. Hospitalized sHF patients had significantly (p < 0.01) greater comorbidity, lower use of recommended HF therapies, longer length of stay (10.8 ± 10.1 vs. 9.7 ± 7.9 days), and higher in-hospital and 1-year mortality (32 vs. 25.8%) with no significant differences in readmission rates and lower 1-year re-ED visit rate. Hospitalized sHF patients had higher total costs (€12,262,422 vs. €9,144,952, p < 0.001), mean cost per patient-year (€9,755 ± 13,395 vs. €8,887 ± 12,059), and average daily cost per patient. Conclusion: Hospitalized sHF patients have a worse initial prognosis, greater use of healthcare resources, and higher costs.

Influenza vaccine improves cardiovascular outcomes in patients with coronary artery disease: A systematic review and meta-analysis.

BACKGROUND: There are inconsistent data on the clinical benefit of the influenza vaccine on cardiovascular outcomes in patients with coronary artery disease (CAD). Therefore, the aim of our study was to evaluate the effect of the influenza vaccine on cardiovascular outcomes in CAD patients. METHODS: We searched four electronic databases from inception to September 21, 2021. Randomized controlled trials (RCTs) assessing the efficacy of influenza vaccine in CAD patients were included. The primary outcome was major adverse cardiovascular events (MACE) and secondary outcomes were all-cause mortality, cardiovascular mortality, and myocardial infarction. The risk of bias was assessed using the Cochrane Risk of Bias 2.0 tool. Effect sizes were expressed as risk ratio (RR) with its 95% confidence interval (CI). All meta-analyses were performed using a random-effects model. RESULTS: Five RCTs involving 4211 patients were included. The mean age ranged from 54.5 to 67 years and 75% of patients were men. Influenza vaccine significantly reduced the risk of MACE (RR, 0.63; 95% CI, 0.51-0.77), all-cause mortality (RR, 058; 95% CI, 0.4-0.84) and cardiovascular mortality (RR, 0.53; 95% CI, 0.38-0.74) compared to control group. The risk of myocardial infarction was similar between both groups (RR, 0.69; 95% CI, 0.47-1.02). The certainty of the evidence was low for MACE, all-cause mortality, and cardiovascular mortality and was very low for myocardial infarction. CONCLUSIONS: Our review shows that the influenza vaccine may reduce cardiovascular events in CAD patients. Therefore, we suggest that it be actively applied as part of secondary prevention in this population.
