概括

修改的右心室中风工作指数 (mRVSWI) 能够有效预测右心室外流通道重建 (RVOTR) 后患者的预后. 较高的mRVSWI值与RVOTR患者的重新手术率增加和较差的结果相关.

科学领域:

心脏病学心脏病学
心脏外科手术心脏外科手术
血液动力学血液动力学

背景情况:

评估右心室工作负荷后右心室外流通道重建 (RVOTR) 是由于结合的狭窄性和反性病变而具有挑战性.
标准右心室中风作业指数 (RVSWI) 可能无法完全捕捉这些患者的复杂血液动力学负载.

研究的目的:

修改RVSWI (mRVSWI) 以更好地评估RVOTR后的右心室工作负载.
评估mRVSWI与患者预后之间的关系,包括重新手术率和生存率.

主要方法:

招募了69名接受RVOTR的患者和13名年龄匹配的对照.
在RVOTR后一年,通过导管测量了mRVSWI.
将RVOTR亚组 (早期重新手术与随访) 和对照组之间的mRVSWI进行比较,并评估其对避免重新手术和生存的影响.

主要成果:

RVOTR患者的mRVSWI显著高于对照组 (17.7比11.0g·m/m2).
需要早期重新手术的患者的mRVSWI比随访小组的患者高得多 (32.5vs15.8g·m/m2).
在随访组中,较高的mRVSWI (>16.4 g·m/m2) 预测了更多的重新手术需要 (p=0.0013).

结论:

该mRVSWI有效地整合了右心室的压力和体积负荷.
这种修改后的指数证明了在预测RVOTR后患者预后的有用性.

Cardiac Output II: Effect of Stroke Volume on Cardiac Output

Cardiac Output II: Effect of Stroke Volume on Cardiac Output

Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...
