Real world heart failure epidemiology and outcome: A population-based analysis of 88,195 patients

BackgroundHeart failure (HF) is frequent and its prevalence is increasing. We aimed to evaluate the epidemiologic features of HF patients, the 1-year follow-up outcomes and the independent predictors of those outcomes at a population level.Methods and resultsPopulation-based longitudinal study including all prevalent HF cases in Catalonia (Spain) on December 31st, 2012. Patients were divided in 3 groups: patients without a previous HF hospitalization, patients with a remote (>1 year) HF hospitalization and patients with a recent (ConclusionsOutcomes are different depending on the HF population studied. Some comorbidity, an all-cause hospitalization or emergency department visit the previous year were associated with a worse outcome.

【背景】心力衰竭（Heart Failure, HF）为临床高发疾病，且其患病率呈持续上升趋势。本研究旨在从人群层面评估心力衰竭患者的流行病学特征、1年随访结局以及该类结局的独立预测因素。
【方法与结果】本研究为基于人群的纵向研究，纳入了2012年12月31日西班牙加泰罗尼亚地区的所有现症心力衰竭病例。将受试患者分为3组：既往无心力衰竭住院史的患者、既往心力衰竭住院时间距今超过1年的患者，以及近期心力衰竭住院的患者。
【结论】不同研究队列的心力衰竭患者结局存在差异。部分合并症、前一年发生的全因住院或急诊就诊事件，均与不良结局显著相关。
