“If an old man’s heart relaxes slowly, his capacity for physical exertion is thus limited, even though the systolic contractions were still like those of youth.”(老人の心臓がゆっくりと拡張するなら,たとえ収縮能が若い人と同じであっても運動能力は制限されるであろう.)1923 年の Physiological Review に載っている Henderson の言葉である.90 年以上前に高齢化社会における拡張不全の出現を予言していたのである.(拡張不全とはどのような心不全のことをいうのでしょうか? 拡張不全の疫学)

This included those with peak exercise pulmonary vascular resistance <1.74 Woods units.41,42 The RESPONDER-HF studying this particular subgroup is ongoing (NCT05425459).
