Heart failure with preserved ejection fraction (HFpEF) or diastolic heart failure (DHF) makes up more than half of all congestive heart failure presentations (CHF). With an ageing population, the case load and the financial burden is projected to increase, even to epidemic proportions. CHF hospitalizations add too much of the financial and infrastructure strain. Unlike systolic heart failure (SHF), much is still either uncertain or unknown. Specifically, in epidemiology, the disease burden is established; however, risk factors and pathophysiological associations are less clear; diagnostic tools are based on rigid parameters without the ability to accurately monitor treatments effects and disease progression; finally, therapeutics are similar to SHF but without prognostic data for efficacy.
The last several years have seen guidelines changing to account for greater epidemiological observations. Most of these remain general observation of shortness of breath symptom matched to static echocardiographic parameters. The introduction of exercise diastolic stress test has been welcome and warrants greater focus. HFpEF is likely to see new thinking in the coming decades. This review provides some of perspective on this topic.
射血分数保留的心力衰竭(HFpEF)或舒张性心力衰竭(DHF)占充血性心力衰竭(CHF)所有表现的一半以上(HFpEF)。随着人口老龄化,预计病例数和经济负担将会增加,甚至会达到流行的程度。CHF 住院治疗给医疗财务和基础设施带来了巨大压力。与收缩性心力衰竭(SHF)不同,HFpEF 的很多方面仍然不确定或未知。具体来说,在流行病学中,已经确定了疾病负担;然而,风险因素和病理生理关联尚不清楚;诊断工具基于严格的参数,无法准确监测治疗效果和疾病进展;最后,治疗方法与 SHF 相似,但缺乏疗效的预后数据。
在过去的几年中,指南已经发生了变化,以考虑到更多的流行病学观察结果。其中大多数仍然是对呼吸困难症状的一般观察,与静态超声心动图参数相匹配。运动舒张应激试验的引入受到了欢迎,并值得进一步关注。在未来几十年,HFpEF 可能会有新的思路。这篇综述提供了一些关于这个主题的观点。
