RESUMO
ABSTRACT: Recent studies have proven benefit of SGLT2i drugs in patients with heart failure with reduced ejection fraction (HFrEF), but their safety when combined with angiotensin-neprilysin inhibitor (ARNI) has not been established. The Safety and Efficacy of the Combination of Sacubitril/Valsartan and SGLT2i in HFrEF Patients registry was conducted to address this issue. SECSI registry is a consecutive, observational, retrospective, multicentre study conducted in 3 Heart Failure Units in Spain. It included 144 HFrEF patients who were treated with ARNI and iSGLT2. Data were collected at baseline, month 2, and month 6. The primary endpoint was the estimated glomerular filtration rate (eGFR), after the initiation of ARNI and sodium-glucose cotransporter-2 inhibitors (SGLT2i). Secondary endpoints included potassium levels and functional class (New York Heart Association class). There were 3 prespecified subgroup analyses: Elderly patients (≥70 years), patients with chronic kidney disease (KDIGO classification G3), and the sequence of drug initiation. Mean age was 69.9 ± 10.1 years, and 110 (76.4%) were men. Left ventricular ejection fraction was 32 ± 7.8%, and most patients were symptomatic [123 (87.2%) New York Heart Association II/III/IV]. eGFR decreased at month 2 and this trend was maintained at month 6 [eGFR baseline 68.5 ± 17.3, month 2 62 ± 19.7 and month 6 64.7 ± 8.6 mL/min/1.73 m2 (P < 0.01 for both)]. In prespecified analysis, elder patients and those who simultaneously initiate both treatments showed the steeper decrease in eGFR. To conclude, co-administration of SGLT2i and ARNI in routine care in HFrEF patients produced a slight decrease in eGFR at 6 months of follow-up. This decrease was especially significant in elder patients and those who initiate both drugs simultaneously.

In the presence of the left ventricle hypertrophy (LVH), the differential diagnosis with hypertrophic cardiomyopathy (HCM) or some phenocopy must be always considered, which can be easily suspected when the hypertrophy is markedly asymmetric. However, when the hypertrophy is homogeneous, especially if the patient has concomitant hypertension, it may be a challenge to distinguish between hypertensive and HCM, although some clinical features may help us to suspect it. In addition, patients with HCM may present with exertional angina due to microcirculation involvement in the setting of the hypertrophy itself or dynamic obstruction in the left ventricular outflow tract, but in some cases, the presence of concomitant coronary artery disease must be suspected as the cause of angina, especially if the patient has an intermediate or high-risk probability of having ischemic heart disease. We present the case of a 46-year-old Afro-American man with poorly controlled hypertension who was found to have severe LVH, and who presented with symptoms of exertional angina during follow-up. We will review the clinical features that can help us in the differential diagnosis in this context.
Ante la presencia de hipertrofia del ventrículo izquierdo (HVI), siempre se debe considerar el diagnóstico diferencial con la miocardiopatía hipertrófica (MCH) o alguna fenocopia, que puede sospecharse fácilmente cuando la hipertrofia es marcadamente asimétrica. Además, los pacientes con MCH pueden presentar angina de esfuerzo debido a la afectación de la microcirculación en el contexto de la propia hipertrofia o si ésta condiciona obstrucción dinámica al tracto de salida del ventrículo izquierdo, pero en algunos casos debe sospecharse la presencia de enfermedad coronaria concomitante como causa de la angina, especialmente si el paciente tiene una probabilidad de riesgo intermedio o alto de padecer cardiopatía isquémica. Presentamos el caso de un varón de 46 años de afroamericana con hipertensión arterial mal controlada a quien se le detectó una HVI severa, y que durante el seguimiento presentó síntomas de angina de esfuerzo. Revisaremos las características clínicas que nos pueden ayudar en el diagnóstico diferencial en este contexto.
RESUMO
INTRODUCTION AND OBJECTIVES: Patients with combined heart failure (HF) and chronic kidney disease (CKD) have been underrepresented in clinical trials. The prevalence of CKD in these patients and their clinical profile require constant evaluation. This study aimed to analyze the prevalence of CKD, its clinical profile, and patterns of use of evidence-based medical therapies in HF across CKD stages in a contemporary cohort of ambulatory patients with HF. METHODS: From October 2021 to February 2022, the CARDIOREN registry included 1107 ambulatory HF patients from 13 HF clinics in Spain. RESULTS: The median age was 75 years, 63% were male, and 48% had heart failure with reduced left ventricular ejection fraction (HFrEF). A total of 654 (59.1%) had an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2, and 122 (11%) patients with eGFR ≥ 60 mL/min/1.73 m2 had a urine albumin-creatinin ratio ≥ 30 mg/g. The most important variables associated with lower eGFR were age (R2=61%) and furosemide dose (R2=21%). The proportion of patients receiving an angiotensin-converting enzyme inhibitor (ACEI)/ angiotensin II receptor blockers (ARB), an angiotensin receptor-neprilysin inhibitor (ARNi), a sodium-glucose cotransporter 2 inhibitor (SGLT2i), or a mineralocorticoid receptor antagonist (MRA) progressively decreased with lower eGFR categories. Notably, 32% of the patients with HFrEF and an eGFR <30 mL/min/1.73 m2 received the combination of ACEI/ARB/ARNi+beta-blockers+MRA+SGLT2i. CONCLUSIONS: In this contemporary HF registry, 70% of patients had kidney disease. Although this population is less likely to receive evidence-based therapies, structured and specialized follow-up approaches within HF clinics may facilitate the adoption of these life-saving drugs.

BACKGROUND: Genetic disease has recently emerged as a cause of cardiac conduction disorders (CCDs), but the diagnostic yield of genetic testing and the contribution of the different genes to CCD is still unsettled. OBJECTIVES: This study sought to determine the diagnostic yield of genetic testing in young adults with CCD of unknown etiology requiring pacemaker implantation. We also studied the prevalence of rare protein-altering variants across individual genes and functional gene groups. METHODS: We performed whole exome sequencing in 150 patients with CCD of unknown etiology who had permanent pacemaker implanted at age ≤60 years at 14 Spanish hospitals. Prevalence of rare protein-altering variants in patients with CCD was compared with a reference population of 115,522 individuals from gnomAD database (control subjects). RESULTS: Among 39 prioritized genes, patients with CCD had more rare protein-altering variants than control subjects (OR: 2.39; 95% CI: 1.75-3.33). Significant enrichment of rare variants in patients with CCD was observed in all functional gene groups except in the desmosomal genes group. Rare variants in the nuclear envelope genes group exhibited the strongest association with CCD (OR: 6.77; 95% CI: 3.71-13.87). Of note, rare variants in sarcomeric genes were also enriched (OR: 1.73; 95% CI: 1.05-3.10). An actionable genetic variant was detected in 21 patients (14%), with LMNA being the most frequently involved gene (4.6%). CONCLUSIONS: Unrecognized rare genetic variants increase the risk of CCD in young adults with CCD of unknown etiology. Genetic testing should be performed in patients age ≤60 years with CCD of unknown etiology. The role of genetic variants in sarcomeric genes as a cause of CCD should be further investigated.
RESUMO
Background: Albuminuria could potentially emerge as a novel marker of congestion in acute heart failure. However, the current evidence linking albuminuria and congestion in patients with congestive heart failure (CHF) remains somewhat scarce. This study aimed to evaluate the prevalence of albuminuria in a cohort of patients with CHF, identify the independent factors associated with albuminuria and analyse the correlation with different congestion parameters. Methods: This is a subanalysis of the Spanish Cardiorenal Registry, in which we enrolled 864 outpatients with heart failure and a value of urinary albumin:creatinine ratio (UACR) at the first visit. Results: The median age was 74 years, 549 (63.5%) were male and 438 (50.7%) had a reduced left ventricular ejection fraction. A total of 350 patients (40.5%) had albuminuria. Among these patients, 386 (33.1%) had a UACR of 30-300 mg/g and 64 (7.4%) had a UACR >300 mg/g. In order of importance, the independent variables associated with higher UACR were estimated glomerular filtration rate determined by the Chronic Kidney Disease Epidemiology Collaboration equation (R2 = 57.6%), systolic blood pressure (R2 = 21.1%), previous furosemide equivalent dose (FED; R2 = 7.5%), antigen carbohydrate 125 (CA125; R2 = 6.1%), diabetes mellitus (R2 = 5.6%) and oedema (R2 = 1.9%). The combined influence of oedema, elevated CA125 levels and the FED accounted for 15.5% of the model's variability. Conclusions: In patients with chronic stable heart failure, the prevalence of albuminuria is high. The risk factors of albuminuria in this population are chronic kidney disease and hypertension. Congestion parameters are also associated with increased albuminuria.
RESUMO
BACKGROUND: Available information about prognostic implications of potassium levels alteration in the setting of acute heart failure (AHF) is scarce. OBJECTIVES: We aim to describe the prevalence of dyskalemia (hypo or hyperkalemia), its dynamic changes during AHF-hospitalization, and its long-term clinical impact after hospitalization. METHODS: We analyzed 1779 patients hospitalized with AHF who were included in the REDINSCOR II registry. Patients were classified in three groups, according to potassium levels both on admission and discharge: hypokalemia (potassium < 3.5 mEq/L), normokalemia (potassium = 3.5-5.0 mEq/L and, hyperkalemia (potassium > 5 mEq/L). RESULTS: The prevalence of hypokalemia and hyperkalemia on admission was 8.2 and 4.6%, respectively, and 6.4 and 2.7% at discharge. Hyperkalemia on admission was associated with higher in-hospital mortality (OR = 2.32 [95% CI: 1.04-5.21] p = 0.045). Among patients with hypokalemia on admission, 79% had normalized potassium levels at discharge. In the case of patients with hyperkalemia on admission, 89% normalized kalemia before discharge. In multivariate Cox regression, dyskalemia was associated with higher 12-month mortality, (HR = 1.48 [95% CI, 1.12-1.96], p = 0.005). Among all patterns of dyskalemia persistent hypokalemia (HR = 3.17 [95% CI: 1.71-5.88]; p < 0.001), and transient hyperkalemia (HR = 1.75 [95% CI: 1.07-2.86]; p = 0.023) were related to reduced 12-month survival. CONCLUSIONS: Potassium levels alterations are frequent and show a dynamic behavior during AHF admission. Hyperkalemia on admission is an independent predictor of higher in-hospital mortality. Furthermore, persistent hypokalemia and transient hyperkalemia on admission are independent predictors of 12-month mortality.

RESUMO
Introducción y objetivos: La eficacia de la administración conjunta de suero salino isotónico y N-acetilcisteína presenta resultados dispares en la prevención de la nefropatía por contraste yodado. Nuestro objetivo fue valorar la posible eficacia de esta estrategia combinada en pacientes con alto riesgo de desarrollar nefropatía inducida por contraste, ingresados y sometidos a intervencionismo coronario percutáneo por síndrome coronario agudo sin elevación del segmento ST en nuestro centro. Método: Se aplicó esta estrategia en los pacientes referidos, con al menos un factor de alto riesgo para desarrollar la nefropatía inducida por contraste: mayores de 80 años, diabetes mellitus, creatinina basal mayor de 1,5 mg/dl o alto volumen de contraste (mayor de 400 ml). El protocolo se aplicó durante 12 meses (pacientes que recibieron el protocolo de prevención) y se comparó con similares pacientes en los 12 meses previos que no recibieron profilaxis. Resultados: Un total de 30 pacientes (24 por ciento) desarrollaron nefropatía inducida por contraste. El porcentaje fue significativamente mayor en el grupo que no recibió profilaxis: 35,9 por ciento vs. 11,5 por ciento (p = 0.003). Conclusiones: La combinación de N-acetilcisteína por vía oral e hidratación parenteral en pacientes de alto riesgo, con síndrome coronario agudo sin elevación de ST, podría ser beneficiosa para evitar la aparición de la nefropatía inducida por contraste(AU)
