This study aimed to examine the diagnostic pathways and outcomes of patients with heart failure (HF), stratified by left ventricular ejection fraction (EF), and to highlight deficiencies in real-world HF diagnosis and management.
We conducted a retrospective cohort study in Salford, United Kingdom, utilizing linked primary and secondary care data for HF patients diagnosed between January 2010 and November 2019. We evaluated characteristics, diagnostic patterns, healthcare resource utilization, and outcomes. Patients were categorized according to baseline (the latest measure prior to or within 90 days post-diagnosis) as having HF with reduced EF (HFrEF), mildly reduced EF (HFmrEF), or preserved EF (HFpEF). The data encompassed a 2 year period before diagnosis and up to 5 years post-diagnosis. A total of 3227 patients were diagnosed with HF between January 2010 and November 2019. The mean follow-up time was 2.6 [±1.9 standard deviation (SD)] years. The mean age at diagnosis was 74.8 (±12.7 SD) years, and 1469 (45.5%) were female. HFpEF was the largest cohort (46.6%, n = 1505), HFmrEF constituted 16.1% (n = 520), and HFrEF 18.5% (n = 596) of the population, while 18.8% (n = 606) of patients remained unassigned due to insufficient evidence to support categorization. At baseline, measurement of natriuretic peptide (NP; brain NP and N-terminal pro-B-type NP) and echocardiographic report data were available for 592 (18.3%) and 2621 (81.2%) patients, respectively. A total of 2099 (65.0%) of the HF cohort had access to a cardiology-led outpatient clinic prior to the HF diagnosis, and 602 (18.7%) attended cardiac rehabilitation post-diagnosis. The 5 year crude survival rate was 37.8% [95% confidence interval (CI) (35.2-40.7%)], 42.3% [95% CI (38.0-47.2%)], and 45.5% [95% CI (41.0-50.4%)] for HFpEF, HFrEF, and HFmrEF, respectively.
Low survival rates were observed across all HF groups, along with suboptimal rates of NP testing and specialist assessments. These findings suggest missed opportunities for timely and accurate HF diagnosis, a pivotal first step in improving outcomes for HF patients. Addressing these gaps in diagnosis and management is urgently needed.
本研究旨在通过左心室射血分数(EF)分层,研究心力衰竭(HF)患者的诊断途径和结局,并强调HF 诊断和管理方面的实际不足。
我们在英国索尔福德进行了一项回顾性队列研究,利用 2010 年 1 月至 2019 年 11 月间 HF 患者的初级和二级医疗数据进行分析。我们评估了特征、诊断模式、医疗资源利用情况和结局。患者根据基线(诊断前或诊断后 90 天内的最新测量值)分为射血分数降低型心力衰竭(HFrEF)、射血分数轻度降低型心力衰竭(HFmrEF)或射血分数保留型心力衰竭(HFpEF)。数据包括诊断前 2 年和诊断后 5 年的资料。2010 年 1 月至 2019 年 11 月期间,共诊断出 3227 例 HF 患者。平均随访时间为 2.6 [±1.9 标准差(SD)]年。诊断时的平均年龄为 74.8 [±12.7 SD]岁,其中 1469 例(45.5%)为女性。HFpEF 是最大的队列(46.6%,n=1505),HFmrEF 占 16.1%(n=520),HFrEF 占 18.5%(n=596),18.8%(n=606)的患者由于缺乏支持分类的证据而无法分类。在基线时,592 例(18.3%)患者的脑钠肽(NP)和 N 末端 pro-B 型 NP 检测数据和 2621 例(81.2%)患者的超声心动图报告数据可用。HF 队列中有 2099 例(65.0%)在 HF 诊断前可获得心脏科主导的门诊治疗,602 例(18.7%)在诊断后接受了心脏康复治疗。HFpEF、HFrEF 和 HFmrEF 的 5 年粗生存率分别为 37.8%[95%置信区间(CI)(35.2-40.7%)]、42.3%[95% CI(38.0-47.2%)]和 45.5%[95% CI(41.0-50.4%)]。
所有 HF 组的生存率均较低,NP 检测和专科评估的比例也不理想。这些发现表明,HF 及时准确诊断的机会被错失,这是改善 HF 患者结局的关键第一步。迫切需要解决这些诊断和管理方面的差距。
