概括
左心室喷射分数 (LVEF) 和LV终端-透析直径 (LVEDd) 预测了在动脉置换 (AVR) 后感染性内心炎 (IE) 患者的结果. 在女性患者中特别注意到较差的结果,突出了性别特异性风险概况.
科学领域:
- 心脏病学 心脏病学
- 心脏外科手术 心脏外科手术
- 心声回声扫描 (Echocardiography) 是一种心声回声扫描.
背景情况:
- 左心室喷射分数 (LVEF) 和LV末腹径 (LVEDd) 是已确定的心血管事件预测指标.
- 它们与感染性内心炎 (IE) 患者的存活率的相关性在接受主动脉置换 (AVR) 的患者中仍未得到充分研究.
- 性对修改这些关联的潜力需要调查.
研究的目的:
- 为了研究LVEF,LVEDd和IE患者治疗AVR的存活率之间的关联.
- 为了确定性别是否改变了这些心声回声学参数和患者结果之间的关系.
主要方法:
- 从三家斯堪的纳维亚心脏手术中心对170名IE患者进行AVR治疗的回顾性分析.
- 采集和分析了手术前和手术后心声学数据.
- 基线特征,并发症和心声回声数据在1年和5年随访后的幸存者和非幸存者之间的比较.
主要成果:
- 术后LVEF降低 (<50%) 在非幸存者中更为频繁 (46.2%与26.2%,p=0.040),特别是在女性中 (71.4%与25.9%,p=0.025).
- 与幸存者相比,已死亡的女性患者的术前LVEF减少率 (<50%) 较高 (30.0%对4.2%,p=0.033).
- 女性非幸存者在短期 (5.7比4.9厘米,p=0.043) 和长期随访 (5.5比4.8厘米,p=0.046) 期间的LVEDd明显高于幸存者.
结论:
- 术前和术后的LVEF和术前的LVEDd与接受AVR的IE患者的治疗结果较差有关.
- 这些关联在女性患者中尤为明显,表明性别特定的风险概况.
- 考虑到性别特异性风险的量身定制的临床管理策略至关重要;需要进一步的研究来验证发现和开发干预措施.

Endocarditis I: Introduction
376
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

Aortic Regurgitation III: Medical Management
383
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Endocarditis IV: Nursing Management
308
Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Aortic Regurgitation I: Introduction
444
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Endocarditis II: Clinical Features of Infective Endocarditis
394
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
