BACKGROUND HFmrEF has been recently proposed as a distinct HF phenotype. How HFmrEF differs from HFrEF and HFpEF according to age remains poorly defined. We aimed to investigate age-dependent differences in heart failure with mid-range (HFmrEF) vs. preserved (HFpEF) and reduced (HFrEF) ejection fraction. METHODS AND RESULTS 42,987 patients, 23% with HFpEF, 22% with HFmrEF and 55% with HFrEF, enrolled in the Swedish heart failure registry were studied. HFpEF prevalence strongly increased, whereas that of HFrEF strongly decreased with higher age. All cardiac comorbidities and most non-cardiac comorbidities increased with aging, regardless of the HF phenotype. Notably, HFmrEF resembled HFrEF for ischemic heart disease prevalence in all age groups, whereas regarding hypertension it was more similar to HFpEF in age ≥ 80 years, to HFrEF in age < 65 years and intermediate in age 65-80 years. All-cause mortality risk was higher in HFrEF vs. HFmrEF for all age categories, whereas HFmrEF vs. HFpEF reported similar risk in ≥ 80 years old patients and lower risk in < 65 and 65-80 years old patients. Predictors of mortality were more likely cardiac comorbidities in HFrEF but more likely non-cardiac comorbidities in HFpEF and HFmrEF with < 65 years. Differences among HF phenotypes for comorbidities were less pronounced in the other age categories. CONCLUSION HFmrEF appeared as an intermediate phenotype between HFpEF and HFrEF, but for some characteristics such as ischemic heart disease more similar to HFrEF. With aging, HFmrEF resembled more HFpEF. Prognosis was similar in HFmrEF vs. HFpEF and better than in HFrEF.

与射血分数降低或保持的心力衰竭相比,中程射血的心力衰竭的临床表型和预后的年龄依赖性差异。

背景技术最近已经提出HFmrEF作为独特的HF表型。根据年龄,HFmrEF与HFrEF和HFpEF的区别仍然不清楚。我们的目的是调查中程(HFmrEF)与保留(HFpEF)和射血分数(HFrEF)降低之间的年龄依赖性心力衰竭差异。方法和结果研究了瑞典心力衰竭登记处的42987例患者,其中HFpEF占23%,HFmrEF占22%,HFrEF占55%。随着年龄的增长,HFpEF的患病率急剧上升,而HFrEF的患病率急剧下降。所有心脏合并症和大多数非心脏合并症都随着年龄的增长而增加,而与HF表型无关。值得注意的是,HFmrEF在所有年龄段的缺血性心脏病患病率中均与HFrEF相似,而对于高血压,它与≥80岁的HFpEF和< 65岁,年龄在65-80岁之间。在所有年龄段中,HFrEF与HFmrEF的全因死亡率风险均较高,而HFmrEF与HFpEF的报告风险在≥80岁患者中相似,而在<65和65-80岁患者中较低。<65岁时,HFrEF患者的心脏合并症死亡率较高,而HFpEF和HFmrEF患者的非心脏合并症死亡率较高。在其他年龄组中,合并症的HF表型之间的差异不太明显。结论HFmrEF表现为HFpEF和HFrEF之间的中间表型,但对于某些特征,例如缺血性心脏病,与HFrEF更相似。随着年龄的增长,HFmrEF更像是HFpEF。HFmrEF与HFpEF的预后相似,且优于HFrEF。在所有年龄段中,HFrEF与HFmrEF的全因死亡率风险均较高,而HFmrEF与HFpEF的报告风险在≥80岁患者中相似,而在<65和65-80岁患者中较低。<65岁时,HFrEF患者的心脏合并症死亡率较高,而HFpEF和HFmrEF患者的非心脏合并症死亡率较高。在其他年龄组中,合并症的HF表型之间的差异不太明显。结论HFmrEF表现为HFpEF和HFrEF之间的中间表型,但对于某些特征,例如缺血性心脏病,与HFrEF更相似。随着年龄的增长,HFmrEF更像是HFpEF。HFmrEF与HFpEF的预后相似,且优于HFrEF。在所有年龄段中,HFrEF与HFmrEF的全因死亡率风险均较高,而HFmrEF与HFpEF的报告风险在≥80岁患者中相似,而在<65和65-80岁患者中较低。<65岁时,HFrEF患者的心脏合并症死亡率较高,而HFpEF和HFmrEF患者的非心脏合并症死亡率较高。在其他年龄组中,合并症的HF表型之间的差异不太明显。结论HFmrEF表现为HFpEF和HFrEF之间的中间表型,但对于某些特征,例如缺血性心脏病,与HFrEF更相似。随着年龄的增长,HFmrEF更像是HFpEF。HFmrEF与HFpEF的预后相似,且优于HFrEF。HFpEF在≥80岁的患者中报告了相似的风险,在<65和65-80岁的患者中报告了较低的风险。<65岁时,HFrEF患者的心脏合并症死亡率较高,而HFpEF和HFmrEF患者的非心脏合并症死亡率较高。在其他年龄组中,合并症的HF表型之间的差异不太明显。结论HFmrEF表现为HFpEF和HFrEF之间的中间表型,但对于某些特征,例如缺血性心脏病,与HFrEF更相似。随着年龄的增长,HFmrEF更像是HFpEF。HFmrEF与HFpEF的预后相似,且优于HFrEF。HFpEF在≥80岁的患者中报告了相似的风险,在<65和65-80岁的患者中报告了较低的风险。<65岁时,HFrEF患者的心脏合并症死亡率较高,而HFpEF和HFmrEF患者的非心脏合并症死亡率较高。在其他年龄组中,合并症的HF表型之间的差异不太明显。结论HFmrEF表现为HFpEF和HFrEF之间的中间表型,但对于某些特征,例如缺血性心脏病,与HFrEF更相似。随着年龄的增长,HFmrEF更像是HFpEF。HFmrEF与HFpEF的预后相似,且优于HFrEF。在其他年龄组中,合并症的HF表型之间的差异不太明显。结论HFmrEF表现为HFpEF和HFrEF之间的中间表型,但对于某些特征,例如缺血性心脏病,与HFrEF更相似。随着年龄的增长,HFmrEF更像是HFpEF。HFmrEF与HFpEF的预后相似,且优于HFrEF。在其他年龄组中,合并症的HF表型之间的差异不太明显。结论HFmrEF表现为HFpEF和HFrEF之间的中间表型,但对于某些特征,例如缺血性心脏病,与HFrEF更相似。随着年龄的增长,HFmrEF更像是HFpEF。HFmrEF与HFpEF的预后相似,且优于HFrEF。
