Clinical outcomes of patients with heart failure and atrial fibrillation: Experience from an outpatient heart failure clinic in Colombia.

Background: Heart failure (HF) can coexist with atrial fibrillation in up to 60 % of cases, increasing rates of hospitalizations and death. This study analyzed the clinical characteristics, treatment, hospitalization, and mortality of patients with HF and atrial fibrillation based on left ventricular ejection fraction (LVEF).

Methods: A retrospective cohort study included patients from an outpatient HF clinic at Medellín (Colombia) between 2020-2022.

Cytomegalovirus Disease, Short-Term Cardiovascular Events and Graft Survival in a Cohort of Kidney Transplant Recipients With High CMV IgG Seroprevalence.

Introduction: Both cytomegalovirus (CMV) infection and CMV disease have been linked with several long-term indirect effects in kidney transplant recipients. Research questions: We conducted a retrospective study to assess the association between cytomegalovirus disease and risks of death, shortterm cardiovascular events and graft loss in a cohort of renal transplant recipients.

Design: The associations between CMV disease and death and cardiovascular events were determined using Cox regression models, while the association between viral disease and graft loss risk was analyzed through a competing risks regression according to the Fine and Gray method.
