The long-term prognosis of patients with heart failure with preserved left ventricular ejection fraction (HFPEF) and coexistent chronic obstructive pulmonary disease (COPD) has not been previously investigated. The primary aim of this study was to determine whether the long-term prognosis of HFPEF patients with COPD differs from that of heart failure patients with reduced left ventricular ejection fraction (HFREF) and COPD. The secondary aim was to identify independent predictors of event-free survival in patients with HF and COPD.
We investigated 184 patients with coexistent HF and COPD. Heart failure with preserved left ventricular ejection fraction was present in 98 cases (53%) and HFREF in the remaining 86 cases (47%). Mean follow-up time was 731±369 days. Cardiovascular/pulmonary hospitalization or mortality occurred in 71 patients (39%). No significant difference was observed between the two study groups in terms of event-free survival (P=0.457), but event-free survival was found to be independently associated with New York Heart Association (NYHA) class [III vs. I, hazard ratio (HR) 2.92, 95% confidence interval (CI) 1.09-7.82], Global initiative for chronic Obstructive Lung Disease (GOLD) stage (III vs. I, HR 3.20, 95% CI 1.33-7.68), systemic hypertension (SHT; HR 2.99, 95% CI 1.41-6.33), and pulmonary hypertension (PH; HR 4.35, 95% CI 1.95-9.68).
In HF patients with coexisting COPD, cardiovascular and pulmonary event-free survival of HFPEF was found to be similar to that of HFREF over 3 years follow-up. Furthermore, severe NYHA class, severe GOLD stage, SHT, and PH were found to be independent predictors of event-free survival.
患有射血分数保留的心力衰竭(HFPEF)合并慢性阻塞性肺疾病(COPD)患者的长期预后尚未得到研究。本研究的主要目的是确定 COPD 合并 HFPEF 患者的长期预后是否与射血分数降低的心力衰竭(HFREF)和 COPD 患者不同。次要目的是确定 HF 和 COPD 患者无事件生存的独立预测因素。
我们研究了 184 例合并 HF 和 COPD 的患者。HFPEF 患者 98 例(53%),HFREF 患者 86 例(47%)。平均随访时间为 731±369 天。心血管/肺部住院或死亡发生在 71 例患者(39%)中。两组在无事件生存方面无显著差异(P=0.457),但无事件生存与纽约心脏协会(NYHA)分级[III 级与 I 级,风险比(HR)2.92,95%置信区间(CI)1.09-7.82]、全球慢性阻塞性肺疾病倡议(GOLD)分期(III 级与 I 级,HR 3.20,95%CI 1.33-7.68)、系统性高血压(SHT;HR 2.99,95%CI 1.41-6.33)和肺动脉高压(PH;HR 4.35,95%CI 1.95-9.68)独立相关。
在合并 COPD 的 HF 患者中,HFPEF 患者在 3 年的随访中,心血管和肺部无事件生存与 HFREF 相似。此外,严重的 NYHA 分级、严重的 GOLD 分期、SHT 和 PH 是无事件生存的独立预测因素。
