纽约心脏协会（NYHA）心力衰竭功能分级
NYHA分级	定义	限制	举例
I	日常体力活动不会导致过度疲劳、呼吸困难或心悸	无	能完成任何需要≥7 MET的活动：携带超过11公斤（24磅）物品上楼承载重量为23公斤（50磅）铲雪锄地滑雪打壁球，手球，或篮球以≥6.9公里/小时（≥4.3英里/小时）的速度慢跑或快走
II	休息时尚可；日常体力活动会引起疲劳、呼吸困难、心悸或心绞痛	轻度	能够完成需要≥ 5但≤ 7个代谢当量的活动：剧烈的性活动可完成花园工作滑旱冰在平地上以最高7公里/小时（4.4英里/小时）的速度进行快走携带11公斤（24磅）的负荷上楼梯
III	休息时尚可；轻微的体力活动可引起乏力，呼吸困难，心悸或心绞痛 IIIa级：无近期心力衰竭加重或近期静息时呼吸困难 IIIb级：伴有近期心力衰竭加重或近期静息时呼吸困难	中度	能够完成需要≥ 2且≤5个代谢当量的活动：站立淋浴或穿衣中度的家务清洁（例如擦窗、扫地、吸尘、厨房活动）打高尔夫球在平地上以最高5.4公里/小时（3.4英里/小时）的速度行走缓慢爬楼梯
IV	静息状态下即出现症状；任何体力活动均会加重不适感。	重度	所有活动均伴随症状无法完成任何需要 ≥ 2个代谢当量的活动（包括上述所有活动）
HF = 心力衰竭，MET = 代谢当量，用于衡量与静息状态相比所消耗能量的单位；mph = 英里/小时。
