概括

较大的心脏病发作大小增加了二次出血转化在急性缺血性中风的风险,无论rt-PA治疗. 管理风险因素可以防止中风和转变.

科学领域:

神经学神经学
放射学放射学是一门学科.
内部医学内部医学

背景情况:

确定二次出血转变的预测因素对于急性缺血性中风管理至关重要.
二次出血转变 (HI和PH) 是中风后的一个重要并发症,特别是在血栓消毒疗法中.

研究的目的:

确定自发性二次出血变化的临床,实验室和放射学预测因素.
在rt-PA治疗和未治疗的急性缺血性中风患者中调查这些预测因素.

主要方法:

追溯分析909名急性缺血性中风患者 (161人接受rt-PA治疗,748人未接受治疗) 的MRI.
用ANOVA和回归分析分析了临床,实验室和放射学数据.
评估了中风后5天内发生的出血性心脏病发作 (HI) 和腹膜性出血 (PH).

主要成果:

接受rt-PA治疗的患者的临床状况更严重,心脏病发作量更大,HI和PH的发病率更高.
在未接受治疗的患者中,临床状态在HI/PH患者和没有HI/PH患者之间没有差异.
心房动,糖尿病和心脏病发作量被确定为HI和PH的显著预测因素.

结论:

更大的心脏病发作大小与急性缺血性中风中二次出血转变的风险增加有关,有或没有rt-PA.
降低风险因素可以防止缺血性中风及其二次出血转变.
心脏病发作体积的放射性评估是出血转变的相关预后因素.

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...
