概括

穿皮冠状动脉干预 (PCI) 后左心室末端透气压 (LVEDP) 升高显著增加1年死亡风险. 这种风险在左心室喷射分数减少的患者中进一步放大.

科学领域:

心脏病学心脏病学
干预心脏病学干预心脏病学
这是心脏衰竭.

背景情况:

左心室末端透气压 (LVEDP) 是一个关键的血液动力学参数.
升高的LVEDP与穿皮冠状动脉干预 (PCI) 后不良结果有关,特别是在急性冠状动脉综合征 (ACS) 中.
需要进一步阐明LVEDP对慢性冠状动脉综合征 (CCS) 或接受PCI的ACS患者结局的影响.

研究的目的:

评估接受PCI的患者中LVEDP水平与1年全因死亡率之间的关联.
研究LVEDP对患有慢性冠状动脉综合征或ACS的患者结局的影响.
检查高LVEDP和降低左心室喷射率 (LVEF) 对死亡率的综合影响.

主要方法:

2014年至2021年间连续接受PCI的患者的回顾性分析.
根据LVEDP,患者被分为三个分层:≤14mmHg,15-20mmHg和>20mmHg.
主要结局是1年全因死亡率;补充分析评估了最高LVEDP组的LVEF影响.

主要成果:

患有LVEDP>20毫米平的患者表现出更高的并发症患病率和冠状动脉疾病复杂性.
与≤14mmHg的LVEDP相比,高的LVEDP与1年全因死亡率显著增加有关 (aHR为15-20mmHg1.47;aHR为>20mmHg3.00).
在LVEDP>20mm Hg,LVEF<40%的患者中,与更高的一年死亡风险 (aHR2.71) 有关.

结论:

在CCS或ACS患者中,升高的LVEDP是PCI后1年死亡率增加的显著预测因素.
较高的LVEDP水平与较差的临床结果相关.
系统性功能障碍,以降低的LVEF表示,加剧了严重升高LVEDP (>20毫米升) 的患者的死亡风险.

Mitral Stenosis I: Introduction

Mitral Stenosis I: Introduction

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Cardiac Catheterization II: Right Heart Catheterization

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
