[Usefulness of e-consultation in cardiology]. / Utilidad de la teleconsulta en cardiología.

INTRODUCTION AND OBJECTIVES: The development of IT tools and interlevel relationships in the management of the most prevalent processes has led to a semi-presential assessment approach. In cardiology, this form of assessment is possible through a close collaboration with primary care. The aim of this study is to analyze the results of our e-consultation program and to establish the effectiveness of this new form of assistance. METHODS: Single-center study that included e-consultations referred from 15 September 2021 to 30 September 2022. Subsequently, we analyzed the events in which patients were discharged directly during the e-consultation with no need for an on-site visit. RESULTS: We included 3,155 e-consultations. The mean age of the patients was 57±17.6 years. Of the consultations, 75% were answered within 48h (62% within 24h). A total of 1,988 patients completed one year of follow-up in e-consultation. Out of these, 1,278 patients (64.2%) were discharged from the e-consultation with no need for an on-site visit: 685 patients (53.5%) during the first consultation, and 593 (46.5%) upon request of a complementary test. After one year of follow-up, 13 patients (0.006%) were admitted due to cardiological pathology, and 16 patients (0.008%) died, only one due to cardiovascular causes. The mean age of the deceased was 80.5 years. CONCLUSIONS: E-consultation as a single referral system from primary care to cardiology improves patient accessibility, speeds up patient assessment and is effective for patients discharged without the need for an on-site consultation.

[Serum potassium levels and long-term mortality in the elderly with hypertension]. / Niveles de potasio sérico y mortalidad a largo plazo en ancianos con hipertensión arterial.

There is increasing evidence that small variations within the normal range (3.5-5mEq/L) of potassium are associated with mortality. OBJECTIVE: To determine whether there is an association between serum potassium level (sK) and mortality in a cohort of elderly hypertensive patients. PATIENTS AND METHODS: A retrospective, observational study was conducted on patients who had sK levels available in a period of clinical stability during their recruitment between January and April 2006 and followed-up for 10 years. The study obtained a total of 62 stable patients, with a mean age of 82.19±6 years (range 69-97), with 74.2% women, 33.9% diabetics, 20.3% with a history of heart failure, Ischaemic heart disease was observed in 19.4% and 44.3% received Angiotensin Converting Enzyme (ACE) inhibitors. An analysis was performed on the mortality rate during the 10 year period. The statistics were performed using the SPSS15.0 package. RESULTS: There were 49 deaths. The sK had a normal distribution. Baseline mean sK levels and median were 4.45±0.5mEq/L (range 3.1-5.5 mEq/L). Baseline sK levels were significantly higher in diabetic patients and patients on ACE inhibitors. The patients that died had higher sK levels (4.53±0.49mEq/L versus 4.14±0.40mEq/L, P=.011). Survival estimated using Kaplan Meier showed that patients with sK levels higher than the median and P75 had higher mortality. CONCLUSIONS: In our study, sK levels greater than 4.45mEq/L were associated with mortality. When selecting antihypertensive treatment in hypertensive elderly patients,, the use of ACE inhibitors should be assessed individually, with close monitoring at sK levels and try to keep them in the lower limit of the normal range (<4.45 mEq/L).

[Elevated serum aldosterone levels in dialysis patients: Are we underusing renin-angiotensin-aldosterone system blockers?] / Niveles elevados de aldosterona sérica en pacientes en diálisis: ¿estamos infrautilizando los bloqueantes del sistema renina angiotensina aldosterona en diálisis?

Serum aldosteronelevels (SA) are a marker of cardiovascular (CV) risk in the general population. OBJECTIVE: To analyze SA levels in dialysis patients and its relationship with characteristics of dialysis; comorbidity; blood pressure and the use of blocking renin-angiotensin-aldosterone system agents (BSRAA). METHODS: We determined SA in 102 patients: 81 on hemodialysis (HD) and 21 on peritoneal dialysis. Mean age 71.4±12 years; 54.9% male; 29.4% diabetics. Mean time on dialysis 59.3±67 months. In 44 HD patients plasma renin activity (PRA) was measured. RESULTS: Mean SA was 72.6±114.9ng/dl (normal range 1.17-23.6ng/dl). A total of 57.8% of patients had above normal levels which were not related to dialysis characteristics or comorbidity. Only 21% of patients with heart failure and 19.2% with ischemic heart disease used BSRAA. A number of 25 patients treated with BSRAA had significantly lower levels of SA. There was an inverse correlation between AS and systolic blood pressure (SBP), and direct with PRA. The logistic regression analysis conducted to find SA levels above the median associated factors showed that SBP was the only independent risk variable in the overall population (OR 0.97; P=.022); in the 44 patients in whom PRA was determined this was the only independent risk factor (OR 2.24; P=.012). CONCLUSIONS: A high percentage of dialysis patients have elevated levels of SA that are associated to diminished SBP and activated PRA and not to dialysis characteristics. In patients with a history of heart disease we underuse BSRAA.

Systematic review with meta-analysis: non-alcoholic steatohepatitis - a case for personalised treatment based on pathogenic targets.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is an umbrella term, which encompasses simple steatosis and non-alcoholic steatohepatitis (NASH). The entire spectrum of NAFLD has been associated with metabolic syndrome. NASH is associated with increased mortality compared with that of the general population. Many therapeutic options for NASH have been studied. However, there is very little evidence supporting the efficacy of most regimens for the treatment of NASH. AIM: To provide a review focusing on the current therapeutic options available for patients with NASH as well as to briefly introduce possible future interventions. METHODS: A MEDLINE, Pubmed and Cochrane Review database search using a combination of keywords, which included non-alcoholic fatty liver disease, non-alcoholic hepatic steatosis, NAFLD, NASH, treatment, therapeutics, vitamin E, orlistat and bariatric surgery. An overall summary of the articles was developed for each section of discussion in this review. RESULTS: NASH associated with metabolic syndrome can progress advanced fibrosis and cirrhosis. Weight loss and lifestyle modification have been shown to improve NASH. Other medications used for weight loss and metabolic syndrome have been evaluated, such as orlistat, metformin and thiazolidinediones. Alternative regimens using ursodeoxycholic acid, statins and probiotics as well as bariatric surgery have been evaluated, but have not been recommended as first-line treatment for NASH. Vitamin E for NASH patients without diabetes seems to be promising. The lack of effective treatment for NASH suggests the heterogeneity of patients presenting with the NASH phenotype. The best treatment strategy for these patients may be to identify their pathogenic target and develop personalised treatment protocols. CONCLUSIONS: Currently, there are few options available for the management of NASH. Future targeted treatment strategies based on the pathogenic pathways may be needed to develop effective treatment for patients with NASH.

Relationship between leptin and all–cause and cardiovascular mortality in chronic hemodialysis patients

Background: We aimed to evaluate the relationship between serum leptin and the leptin/body mass index (BMI) ratio with prevalent cardiovascular disease (CVD), and their influence on all–cause and CVD–related mortality in patients on hemodialysis (HD). Methods: 118 stable HD patients (50 women, median [interquartile range] age, 65.1 [54.7–72.2] years) were studied. All patients had baseline measurement of serum leptin concentrations. Relationships between leptin and all–cause and CVD mortality were studied by means of survival analysis and Cox regression analysis. Results: The leptin/BMI ratio was similar in patients with and without CVD at baseline (0.65 [0.29–2.23] vs. 0.68 [0.29–1.49] ng·m2/ml·kg, respectively, NS). Multiple logistic regression analysis showed that there was not an independent association between leptin/BMI ratio and prevalent CVD. During the follow–up time, 52 (44.1%) patients died. CVD was the cause of death in 27 out of 52 (51.9%) deceased patients. Survival analysis and Cox proportional multivariate regression analysis showed that there were no significant relationships between leptin levels or the leptin/BMI ratio and all–cause and CVD–related mortality. Conclusion: These results do not support that, in stable HD patients, serum leptin concentrations and the leptin/BMI ratio are related with prevalent CVD. Leptin/BMI ratio seems not to be a risk factor for mortality in these patients (AU)

Introducción: El objetivo del presente estudio ha sido evaluar la relación entre la leptina sérica y el cociente leptina/índice de masa corporal (IMC) con la enfermedad cardiovascular (ECV) prevalente y su influencia en la mortalidad global y en la mortalidad por ECV en pacientes en hemodiálisis (HD). Métodos: Se estudiaron 118 pacientes estables en HD (50 mujeres, edad mediana [recorrido intercuartílico], 65,1 [54,7–72,2] años). En todos los pacientes se cuantificó la concentración basal de leptina. La relación entre leptina y la mortalidad se evaluó mediante análisis de supervivencia y análisis de regresión de Cox. Resultados: El cociente leptina/IMC fue similar en pacientes con y sin ECV prevalente (0,65 [0,29–2,23] frente a 0,68 [0,29–1,49] ng·m2/ml·kg, respectivamente, NS). El análisis de regresión logística mostró que no existía una asociación independiente entre el cociente leptina/IMC y la enfermedad cardiovascular prevalente. Durante el seguimiento 52 pacientes fallecieron (44,1%). La ECV fue causa de muerte en 27 de 52 pacientes fallecidos (51,9%). El análisis de supervivencia y el análisis multivariante de Cox mostraron que no hubo relación significativa entre los niveles de leptina o el cociente leptina/IMC y la mortalidad global o por causa de ECV. Conclusión: Estos resultados no apoyan la hipótesis de que, en pacientes estables en HD, las concentraciones de leptina y el cociente leptina/IMC estén relacionados con la ECV prevalente. Más aún, el cociente leptina/IMC no parece ser un factor de riesgo de mortalidad en estos pacientes (AU)
