Caracterización de la fibrilación auricular y riesgo tromboembólico en pacientes del Hospital León Cuervo Rubio

Introduction: among cardiac pathologies, atrial fibrillation is related to a high incidence of thromboembolic diseases. Objective: to clinically and epidemiologically characterize atrial fibrillation and thromboembolic risk in patients attended at the León Cuervo Rubio Hospital in Pinar del Río between 2017 and 2019. Methods: an observational, descriptive, cross-sectional, descriptive study was conducted on patients with atrial fibrillation attended at the León Cuervo Rubio Hospital in Pinar del Río from 2017 to 2019. The study universe consisted of 198 patients diagnosed with atrial arrhythmias in that hospital, the sample was constituted by 68 patients who met the inclusion and exclusion criteria. Results: female sex predominated (58.8%). The most representative age group was 75 to 85 years old (45.5 %). Some type of heart disease associated with atrial fibrillation was present in 69.1% of patients. Persistent atrial fibrillation predominated (35.2%). Palpitations predominated as symptoms of atrial fibrillation (91.1%). Most patients with atrial fibrillation were in the moderate thromboembolic risk category (66.1%). Conclusions: the predominant sex was female, the most affected age group was over 85 years, ischemic heart disease was the most prevalent history, persistent atrial fibrillation was the most frequent, palpitations were the main symptom, and according to the thromboembolic risk category, most patients were at moderate risk.Introducción: dentro de las patologías cardiacas, la fibrilación auricular se relaciona con una alta incidencia de enfermedades tromboembólicas. Objetivo: caracterizar clínica y epidemiológicamente la fibrilación auricular y el riesgo tromboembólico en pacientes atendidos en el Hospital León Cuervo Rubio de Pinar del Río entre 2017 y 2019. Método: se realizó un estudio observacional, descriptivo, de corte transversal a pacientes con fibrilación auricular atendidos en el Hospital León Cuervo Rubio de Pinar del Río de 2017 a 2019. El universo de estudio estuvo conformado por 198 pacientes con diagnóstico de arritmias auriculares en dicho hospital, la muestra quedó constituida por 68 pacientes que cumplieron con los criterios de inclusión y exclusión. Resultados: predominó el sexo femenino (58,8 %). El grupo etario más representativo fue el de 75 a 85 años (45,5 %). El 69,1 % presentaban algún tipo de cardiopatía asociada a la fibrilación auricular. Predominó la fibrilación auricular de tipo persistente (35,2 %). Predominaron las palpitaciones como síntomas de la fibrilación auricular (91,1 %). La mayoría de los pacientes con fibrilación auricular estaban en la categoría de riesgo tromboembólico moderado (66,1 %). Conclusiones: el sexo que predominó fue el femenino, el grupo etáreo más afectado fue el de más de 85 años, la cardiopatía isquémica fue el antecedente de mayor prevalencia, la fibrilación auricular de tipo persistente fue la más frecuente, las palpitaciones constituyeron el síntoma principal y según la categoría de riesgo tromboembólico la mayoría de los pacientes presentaban riesgo moderado

Patient-centered interventions to improve medication management and adherence: A qualitative review of research findings

Patient-centered approaches to improving medication adherence hold promise, but evidence of their effectiveness is unclear. This review reports the current state of scientific research around interventions to improve medication management through four patient-centered domains: shared decision-making, methods to enhance effective prescribing, systems for eliciting and acting on patient feedback about medication use and treatment goals, and medication-taking behavior

Outcomes of Cardiac Resynchronization Therapy with Image-Guided Left Ventricular Lead Placement at the Site of Latest Mechanical Activation: A Systematic Review and Meta-Analysis

Aim. To assess evidence for an image-guided approach for cardiac resynchronization therapy (CRT) that targets left ventricular (LV) lead placement at the segment of latest mechanical activation. Methods. A systematic review of EMBASE and PubMed was performed for randomized controlled trials (RCTs) and prospective observational studies from October 2008 through October 2020 that compared an image-guided CRT approach with a non-image-guided approach for LV lead placement. Meta-analyses were performed to assess the association between the image-guided approach and NYHA class improvement or changes in end-systolic volume (LVESV), end-diastolic volume (LVEDV), and ejection fraction (LVEF). Results. From 5897 citations, 5 RCTs including 818 patients (426 image-guided and 392 non-image-guided) were identified. The mean age ranged from 66 to 71 years, 76% were male, and 53% had ischemic cardiomyopathy. Speckle tracking echocardiography was the primary image-guided method in all studies. LV lead placement within the segment of the latest mechanical activation (concordant) was achieved in the image-guided arm in 45% of the evaluable patients. There was a statistically significant improvement in the NYHA class at 6 months (odds ratio 1.66; 95% confidence interval (CI) [1.02, 2.69]) with the image-guided approach, but no statistically significant change in LVESV (MD −7.1%; 95% CI [−16.0, 1.8]), LVEDV (MD −5.2%; 95% CI [−15.8, 5.4]), or LVEF (MD 0.68; 95% CI [−4.36, 5.73]) versus the non-image-guided approach. Conclusion. The image-guided CRT approach was associated with improvement in the NYHA class but not echocardiographic measures, possibly due to the small sample size and a low rate of concordant LV lead placement despite using the image-guided approach. Therefore, our meta-analysis was not able to identify consistent improvement in CRT outcomes with an image-guided approach
