- OBJECTIVES: Levosimendan is a novel inotropic agent claimed to improve myocardial contractility by a calcium-sensitizing effect. Our aim was to evaluate dose-dependent effects of levosimendan on left ventricular (LV) contractility and energetic properties in an acute, ischaemic heart failure porcine

「心筋酸素消費量」
- 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)。
- (PHD.146)
- (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。
- (3)心収縮力
- β刺激薬、強心薬
指標
- 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
