- Para-aortic counterpulsation device (PACD) is a promising therapy for severe heart failure (HF). However, the lack of knowledge about mechanisms has limited its clinical application. The aim of this study was to investigate the optimal timing algorithms. At the following four triggering algorithms,

- 心筋酸素需要 myocardial oxygen demand
- MVO2≒平均収縮期血圧 x 収縮期時間 x 心拍数 (tension-time index: See SAN.176)
- ≒収縮期血圧 x 心拍数 (double product)
- double productは非侵襲的で左室MVO2の目安となる。12,000以上は心筋虚血の危険性がある。
- 心筋酸素消費量 は 心拍数 , 収縮期血圧 , 左室容量 , 心収縮性 に規定される(QB2009.C-336)。

- (1)心室壁ストレス、(2)心拍数、(3)心収縮力
- (1)心室壁ストレス:壁ストレスは心室壁の接線方向の力で、これにあらがうためにO2が必要となる。
- 壁ストレス(σ)=心室内圧力(P)x心室径(r)/(2x壁厚(h))
- Pは収縮期血圧 ← ASや高血圧で↑
- rは心室径 ← AR, MRで↑、硝酸薬で↓
- hは壁厚 ← 壁が厚ければ力が分散するため。ASとか高血圧で壁が肥厚するから、O2の需要は減少する。最も、収縮期血圧が高くなるので、ちょうどO2の需要の増加と相殺されますが。

- pressure rate product PRP = double product = 心拍数 x 収縮期血圧
- systolic pressure time index SPTI = 収縮期血圧 x 収縮期時間
