概括

第一个阶段的左心室喷射分数 (LVEF-1) 有效地表明冠状动脉狭窄的严重程度. 这种敏感标志物在干预治疗后得到改善,有助于监测治疗疗效.

科学领域:

心脏病学心脏病学
医疗成像医学成像
干预心脏病学干预心脏病学

背景情况:

心肌缺血损害了收缩能力,通常会被标准心声回声学遗漏.
第一阶段左心室喷射分数 (LVEF-1) 是心肌收缩性的敏感标志物.

研究的目的:

评估LVEF-1和冠状动脉缺血严重程度之间的相关性.
为了确定LVEF-1是否在干预治疗后得到改善.

主要方法:

207名患者根据冠状动脉狭窄的严重程度 (轻度,中度,严重) 分类.
使用逻辑和线性回归分析LVEF-1,Gensini分数和临床数据的分析.
评估干预后的LVEF-1变化.

主要成果:

LVEF-1与根西尼得分 (r=-0.694,P<0.001) 和BNP (r=-0.244,P<0.001) 呈现出显著的反相关性.
LVEF-1独立地与冠状动脉狭窄相关 (≥50%或≥70%).
干预后LVEF-1得到改善 (24.70%至28.10%),而支架直径预测了改善.

结论:

LVEF-1与冠状动脉狭窄的严重程度有负相关性.
LVEF-1 作为评估狭窄和监测干预治疗疗效的新型指标.

关键词:

根西尼的得分得到了胜利.冠心病是一种冠心病.超声心电图 (Echocardiography) 是一种心声回声仪.第一个阶段的喷射分数.通过皮肤进行冠状动脉干预.

Pathophysiology of Heart Failure

Pathophysiology of Heart Failure

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...
